SOLUTION: This strain detector is provided with a cylindrical resilient element 2 for generating a strain with a load, a resistance element arranged in the resilient element 2 to vary a resistance value in response to a distortion amount, and a signal processing circuit wire-connected to the resistance element. A screw part 4 is formed in upper and lower sides of the resilient element 2 to sandwich the resilient element. While the signal processing circuit is arranged in an inside of a cavity 1 of the resilient element 2, the resistance element is arranged on an outer circumferential face of the resilient element 2, and the resistance element is wire-connected to the signal processing circuit.

摘要： PURPOSE:To provide a load sensor which is excellent in resistance accuracy, cost, mass productivity, reliability and strength regarding the load sensor which is used as a pointing device. CONSTITUTION:In an elastic plate 1, its circumference is fixed at four places, and a glass enamel coating is formed. The elastic plate 1 is deformed by a force which is applied to an operating part 2 which is erected in the center of the elastic plate 1. Its deformation is detected on the basis of a change in resistance values of two pairs of resistance detection elements 5, 5', 6, 6' which have been formed directly on the enamel coating, and the difference in the change between individual pairs of resistance values is operated. Thereby, the direction and the magnitude of the force in the operating part are detected.

摘要： PURPOSE:To detect a load applied to a load cell body without being affected by an unbalanced load concerning a load detector which is adapted to convert a force corresponding to the load into an electrical signal. CONSTITUTION:A distortion resistance layer 5 and electrode layers 3 and 4 are so formed that a distortion resistance body is arranged in the entire circumferential area of the surface of a load cell body 1 formed in a shape of a pipe to build a load detector. In the load detector thus built, the distortion resistance layer 5 is formed in the entire area where a load is applied and hence, even when an unbalanced load works on the load cell body, local changes in the resistance value are turned to a variation value corresponding to all loads applied to the load cell body 1 as total changes in the resistance value though varying with the unbalanced load. This enables accurate detection of the all loads applied to the load cell body 1.

摘要： PURPOSE:To improve the quality and the durability of a load detector by directly forming a strain resistance element on a glass enamel coating which is provided on a metallic elastic body. CONSTITUTION:A load detecting apparatus is constituted of a metallic elastic body 31, a glass enamel coating 32 provided on the metallic elastic body 31 and a strain resistance element 33 which is directly formed on the glass enamel coating 32. A stopper 8 of a bumper rubber 9 and the load detecting apparatus 6 are held between the step-difference part between an intermediate-diameter part 11 of a shock absorber and a small-diameter part 12 of the absorber and a body 1. A suspension spring 7 is attached to a wheel together with the lower end part of a large-diameter part 10 of the absorber. The vehicle suspension formed in this way converts the change in load generated between the body and the wheel into the mechanical strain of the metallic elastic body 31. Then, the strain is converted into the change in strain with the strain resistance element on the glass enamel coating 32, and the electric signal can be detected. Thus, the quality and the durability of the load detector can be improved.

摘要： PURPOSE:To make unnecessary that a current is always impressed on an heating element for a fixed time by providing a function able to detect a printing rate and traverse rapidly for a printer. CONSTITUTION:The function to detect the presence or absence of printing data (printing rate) and traverse rapidly is provided. That is to say, the printing rate of picture information is calculated by a CPU 9 and when the printing of the data of a pre-line already stored in a buffer 10b is terminated, the data of a shift register 10a are moved to the buffer 10b by a latch signal 11. By repeating this action, the printing for one page is executed. Thus, the current is impressed when it is necessary for the printing and when the printing is unnecessary, that is, the printing rate is '0', it is unnecessary to impress the current and a current impressing time can be shortened.

摘要： PURPOSE: To enhance the accuracy and response of a weight sensor. CONSTITUTION: When no weight is applied, a CPU 7 delivers an offset regulation signal 5 corresponding to the offset output drift of a weight sensor. A D/A converter 9 converts the offset regulation signal 5 into an analog signal which is inputted, through reset function, to a DC differential amplifier 4 in order to correct the drift. When a weight is applied, the CPU 7 releases the reset function and offsets the output from a detection circuit 3 immediately before releasing the reset function and outputs the weight of an object 10 in the form of a weight output signal 8. Since the offset output drift it canceled constantly by performing the reset operation automatically, a highly accurate measurement is realized and high response is also realized because the waiting time accompanying conventional manual reset is not required.

摘要： PURPOSE:To make a contactless type displacement detector usable in a wide temperature range by driving a Hall element by a constant current, and constituting an input circuit to the Hall element of a potential dividing circuit formed of at least a thermosensitive resistor and a resistor. CONSTITUTION:A Hall element 3 is driven by a constant current and formed of a gallium arsenide base with an excellent temperature characteristic, and an input circuit is formed of a metal film resistor 1 and a thermosensitive resistor 10. The current to be applied to the element 3 is determined by the combined resistance value of the resistors 1, 10 and uninfluenced by the internal impedance of the element 3. The resistance of the resistor 10 changes according to the ambient temperature, and the effect V1 changes according to the ambient temperature. Even with the rise of ambient temperature, the sensitivity of the element 3 is lowered, and the resistor 10 works in such a way that the effect V1 becomes large before the output of the element 3 becomes low. A bias current to the element 3 therefore becomes large, and the output fluctuation of the element 3 is suppressed to a small quantity.

摘要： PURPOSE:To achieve a highly accurate detection of the number of circuits or the like by arranging a magnetic flux condensing means comprising a conductive material in the perimeter of a magnetic sensor which detects a magnetic field generated by a magnetic field generating means to obtain an electrical signal large in amplitude with a higher density of a magnetic flux so that turbulence is hard to affect. CONSTITUTION:When a magnet 6 for detecting rotation is turned, a magnetic flux changes according to time of the rotation. But as two magnetic condensing members 10 comprising a conductive material contact earth at both ends thereof, eddy currents flow respectively through the members 10. The eddy currents work to keep a magnetic flux generated with the magnet 6 for detecting rotation entering into the magnetic flux condensing members 10. As a result, the magnetic flux is condensed between the flux condensing means 10 and hence, a magnetic sensor 7 can detect a flux density larger as compared with that with the absence of the magnetic flux condensing members 10 thereby enabling highly accurate detection of rotation.
