摘要： PROBLEM TO BE SOLVED: To provide a door catching detecting device for a vehicle precisely deciding that a hand, a foot, or a bag of a person is caught in a door in closing. SOLUTION: After one end of a first pressure passage 22 and one end of a second pressure passage 27 are connected to a pressure unit 35, the other end of the first pressure passage 22 and the other end of the second pressure passage 27 are press-fitted in a reference pressure chamber 7 inside and a pressure chamber 15 inside. In this state, the reference pressure chamber 7 inside and the pressure chamber 15 inside are opened to the outside via a first pressure relief hole 20 and a second pressure relief hole 25 so that, if the first pressure relief hole 20 and the second pressure relief hole 25 are closed by a seal material 33, the reference pressure chamber 7 inside and the pressure chamber 15 inside become the atmospheric pressure of the same level. The differential pressure between the internal pressure of the reference pressure chamber 7 and the internal pressure of the pressure chamber 15 surely exceeds the decision level based on the generation of the door catching so that the presence/absence of the door catching is precisely decided.

摘要： PROBLEM TO BE SOLVED: To provide a device for detecting catching in car doors that can accurately detect whether or not anything is caught in a car door regardless of fluctuations in the ambient temperature, and can reliably assure the safety of the passengers. SOLUTION: A hollow part 33d that can be elastically distorted by external pressure if formed at a door contact 33 of the rubber trim 32 fitted to the edge of a car door, and a hollow part 34a that cannot be elastically distorted is fitted to a fitting 34. This device is configured such that whether or not there is anything caught in the car door based on the differential pressure between the air pressure in the hollow part 33d in the door contact 33 and the air pressure in the hollow part 34a in the fitting 34. Even in the event of fluctuations in the ambient temperature, the air pressure in the hollow part 33d inside the door contact 33 and the air pressure in the hollow part 34a inside the fitting 34 change in the same way. Therefore the fluctuations in the ambient temperature have no effect and the device can accurately detect whether or not anything is trapped in a car door.

摘要： PROBLEM TO BE SOLVED: To provide a device for detecting catching in car doors with increased reliability, to reliably assure the safety of passengers. SOLUTION: This device is configured such that when power is supplied detection signals that indicate whether or not anything is caught in a door are sent and received through an electro-magnetic induction coupling established between a terminal 7 on the vehicle body side and a unit 8 on the car door side. This eliminates the necessary for a cable connecting the vehicle body and car door, and accordingly no risk of disconnection. Also, this means that the catching in a door can be detected reliably, assuring the safety of the passengers and improving reliability.

摘要： PROBLEM TO BE SOLVED: To provide a device to detect trapping of objects in car doors that can reliably assure safety of passengers when getting into and alighting from a vehicle, and can be installed without impairing working efficiency. SOLUTION: This device is configured such that power is supplied and detection signals to indicate whether or not anything is caught in a door are sent and received through an electro-magnetic induction coupling which is established between a terminal 7 on the vehicle body side and a unit 8 on the car door side. Portions in the terminal 7 and the unit 8 are constituted of materials that have a higher magnetic permeability than that of the material making up the vehicle body or car door to which the terminal 7 or the unit 8 is fitted. This eliminates the necessity for a cable between the vehicle body and the car door, and ensures the detection of catching in a door and the safety of passengers can be reliably assured. In addition, when the device is fitted, the electrical characteristics of the coil are not changed under the influence of the material constituting the vehicle body or car door, and therefore all that needs to be done is to adjust the electrical characteristics before fitting the device: working efficiency is not impaired.

摘要： PROBLEM TO BE SOLVED: To provide a device for detecting catching in car doors that can, over the long term, accurately detect whether or not anything is trapped in a car door, even when the rubber trim around the door has lost elasticity and hardened. SOLUTION: When the CPU receives a 'teaching start signal,' it records the differential pressures between the air pressure in the hollow part of the door contact and the air pressure inside the fitting during motion between the closed and open positions of the doors as reference values P0 (S24, 25). When the 'measurement start signal' is received, the differential pressure between the air pressure inside the hollow part of the door contact when the car door is closed and the air pressure inside the hollow part of the fitting is detected as a detected value p (S27). Based on the difference between the detected value P and the reference values P0, it is judged whether or not there is anything caught in the door (S28, S29). Even if the rubber trim around the edge of the door loses elasticity and hardens, no influence is made on the difference between the reference values P0 or the detected value P, enabling accurate detection of, over the long term, whether or not anything is caught in a car door is enabled.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cutting process and an optical fiber cutting tool which can cut an optical fiber so as to have a good cutting plane without requiring a complicated operation. SOLUTION: A fiber holder 15 is disposed in a near center in the groove 14 of a blade holder 13, and is inserted into a fiber holding hole H located between double edges 11 and 12 to be held. Then, the fiber holder 15 is advanced to the first blade 11 side by the rotation operation of a knob part 17, and an optical fiber F is cut off with the first blade 11. At this moment, when an unwanted portion FA is long to some extent, an optical fiber F may cause a rupture phenomenon because there is no recess margin in an axial direction. However, when the knob part 17 is turned in the opposite direction to advance the fiber holder 15 to the second blade 12 side after this, a left optical fiber F is also advanced to the second blade 12 side, and the edge of a blade of the second blade 12 is advanced to the cutting end of the optical fiber F. Because the thin piece part FB is thin in this stage, the second blade 12 is advanced while deforming a thin piece part FB so as to be bent backward. Thereby the thin piece part FB is chipped off without causing a rupture phenomenon to the last, and the cutting plane is smoothed.

摘要： PROBLEM TO BE SOLVED: To provide a visitor/leaver number managing device for counting the number of visitors/leavers with high precision even when any temporary communication error is generated between a detecting unit which detects visitors/leavers and a managing unit which manages the number of visitors/leavers. SOLUTION: A detecting unit 10 counts the cumulative number of visitors/ leavers since start, and periodically outputs the number of visitors/leavers as detection data Xm and Ym by radio. A managing unit 11 receives the detection data Xm and Ym by radio, and updates and stores the data as new management data Xn and Yn. Therefore, the detecting unit 10 itself counts the cumulative number of visitors/leavers Xm and Ym, and transmits the data to the managing unit 11 so that even when errors are generated in radio communication several times in the management period, the correct cumulative number of visitors/ leavers Xm and Ym can be transmitted from the managing unit 11 to the detecting unit 10, and the number of visitors/leavers can be counted with high precision.

摘要： PURPOSE:To prevent the adverse effect due to regularly reflected light from an object to be detected and to enhance detection capacity, by projecting light from a light projecting element through a polarizing filter and receiving detected light by a light receiving element through the polarizing filter. CONSTITUTION:Pulse modulated light 4 is projected from the light projecting element 2 in a case 1 through a vertical polarizing filter 3 and the detected light 4' reflected by a regression mirror 6 is received by a light receiving element 5 through a transverse polarizing filter 7. Because the regrassion mirror 6 has such a characteristic that incident light is reflected therein three times, reflected light comes to one polarized by 90 deg.. When an object 16 to be detected is present in a detection region, the object 16 to be detected has a regularly reflective surface and, therefore, the reflected light thereof has the same phase as the modulated light 4 and is blocked by the polarizing filter 7 and no light is made incident to the light receiving element 5. By this method, erroneous detection due to regularly reflected light can be prevented and detection capacity can be enhanced.
