摘要： PURPOSE:To instantaneously detect urination by providing a urine detecting decision means which generates a urine detecting signal when an output signal level of a water leakage detecting element, provided in the lower in a cage, changes within a range corresponding to urine. CONSTITUTION:A water leakage detecting element 2, in a condition that it is pasted to a sloped surface of a supporting bed, is arranged in a recessed part in a cage inside wall of an elevator, and an output of the element 2 is measured by a measuring means 4 feeding its measured value to a urine detecting decision means 5 here comparing the measured value with a reference value input simultaneously. This reference value is left as previously calculated from a measuring data in the case of detecting urine and rainwater. The urine detecting means 5, when a level of the signal fed from the measuring means 4 is not more than the reference value, judges the urine to be detected, generating a urine detecting signal SN fed to an alarm generating means 6 provided in a supervisor's room or the like, and the alarm generating means 6 receives this signal generating an alarm and informing a supervisor of the signal.

摘要： PURPOSE:To discriminate the kind of liquid with high accuracy regardless of the concn. thereof by collating the electric resistance values before and after the injection of the liquid interposing between electrodes and the rate of the change in the concn. of the liquid by the injection to a table for the change in the electric resistance previously stored. CONSTITUTION:The electric resistance values of the stock solns. of respective samples and the liquids formed by diluting the stock solns. are previously measured and are stored as the table for the change in the electric resistance in a processor 4. The electric resistance of the liquid interposing between the electrodes 6a and 6b is measured and read by a resistance measuring instrument 3. The water injection of a prescribed volume is then executed to lower the concn. of the liquid and the electric resistance between the electrodes 6a and 6b after the water injection is measured. The electric resistance values before and after the water injection and the rate of the change in the concn. of the liquid are collated with the table for the change in the electric resistance, by which the kind of the liquid is discriminated. The kind of the liquid is then displayed on a display device 5. The kind of the liquid is discriminated with the high accuracy in this way regardless of the concn. of the liquid.

CONSTITUTION:A sensor 2 is constituted so that a holding member 2b is fixed to one end surface of a columnar molded part 2a and a pair of electrodes 6a, 6b are held to the leading end of said holding member 2b in a mutually spaced- apart state and the member 2 and the electrodes 6a, 6b are surrounded by the tube 2c fixed to the molded part 2a. The opening part on the side opposite to the fixing side of the molded part of the tube 2c is not sealed and a plurality of air holes 2d communicating with the inside and outside of the tube 2c are provided to the tube 2c in the vicinity of the molded part 2a by drilling. Therefore, when the sensor 2 is inserted in a liquid in such a state that the electrodes 6a, 6b are turned downwardly, the liquid flows in the tube 2c to be interposed between the electrodes 6a, 6b and the electric resistance of the liquid between said electrodes is measured by a resistance measuring device 3 and collimated with the stored kind and electric resistance value of a liquid and the kind of the liquid is judged by an operational processor.

摘要： PURPOSE:To enhance durability and moisture resistance for a joint whose mainframe is made of synthetic resin and has one end fitted into the other end of a fixing member made of metal by forming a plated layer on the outer face of the joint mainframe. CONSTITUTION:A pipe joint 1 comprises a joint mainframe 10 and a fixing member 20. The joint mainframe 10 made of synthetic resin has stage-built concentric holes 11, 12 at one end portion and a connecting mechanism for a pipe (T) inside the other end. The joint mainframe 10 has the outer face provided all over with a plated layer 13 by chemical plating and electric plating. The fixing member 20 made of metal has one end given a male screw portion 22 and the other end provided with fitted portions 23, 24 being different in dia. to be pressed into the joint mainframe 10. As a result, water and moisture resistances are enhances to be free from dislocation of the joint mainframe out of the fixing member when used in atmosphere of high temperature and moisture. It is also possible to prevent of the joint mainframe from being weakened.

摘要： PURPOSE:To make the size of a direction control valve compact by using no complicated solenoid, providing the first valve body between the first and the second ports, and the second valve body between the second and the third ports, and preparing springs to enforce the both valve bodies and electric deforming members to move the both valve bodies separately by applying the current. CONSTITUTION:Between the first port 1 and the second port 2, the first valve body 21 to close and open them is provided, while between the second port 2 and me third port 3, the second valve body 22 is provided in the same manner. The two valve bodies 21 and 22 are enforced by springs 5 and 6 respectively, and they close passages 11 and 12 respectively. Between the first valve body 21 and a valve main body 4, an electric deforming member 13 of a shape memory alloy which is contracted by the heat of the feeding current is extended, contacting an electric operating circuit 19, and when the current is fed to contract and deform the deforming member 13, the first valve body 21 is moved against the spring 5. As a result, the first passage 11 is opened through which a liquid flows. In the same manner, the second passage 12 is opened by feeding the current to an electric deforming member 16 to move the second valve body 22, and the liquid flows through the second passage 12. The two passages 11 and 12 can be opened and closed freely in such a way.

摘要： PURPOSE:To decrease the attenuation and to uniformize the characteristic impedance by arranging a couple of conductors to both faces of a thin and long dielectric string made of an extruded porous polytetrafuluoroethylene opposite to each other and interposing a reinforced layer made of a non-porous plastic between the dielectric and the conductor or in the inside of the dielectric substance. CONSTITUTION:A comparatively thin dielectric substance 2 made of an extruded porous polytetrafuloroethylene(PTFE) is provided in the center in the vertical direction and a thin reinforced layer plate 4 made of a non-porous plastic material is formed to the upper face of the dielectric substance 2. Moreover, a signal line conductor 6 is fixed to the upper face of the reinforced layer 4 in the center in the lengthwise direction, and on the other hand, a ground conductor 8 is fixed to the lower face of the dielectric 2. Furthermore, a coated layer made of a porous PTFE is coated to the upper face of the signal line conductor 6 and the reinforced layer 4 and to the lower face of the ground conductor 8. Thus, the attenuation is decreased and the characteristic impedance is uniformized.

摘要： PURPOSE:To miniaturize a valve, reduce the cost, and allow high-density piping by providing a solenoid driving a spool, a plunger slidably provided in the spool, and an excitation deformation member driving the plunger. CONSTITUTION:To communicate the first port (1) and a common port (3) from the all-port cutoff position, for example, an excitation deformation member 9 is excited, and a plunger 7 provided in a spool 2 is moved from the port cutoff position as a result of this deformation. To communicate the second port (2) and the common port (3), a solenoid 10 is turned on to move the spool 2, and a passage 4 to the second port (2) of the spool 2 is communicated to the common port (3). A directional control valve is obtained which can control three positions: all-port cutoff position, communicating position of the first port (1) and the common port (3), and communicating position of the second port (2) and the common port (3), with only one solenoid 10 by adding the action of the plunger 7.
