IPC: G01G9/00
Filed: 1985-09-03
Abstract: PURPOSE:To constitute the whole of a device easily and in-expensively by supporting elastically an upper receiving base, which receives a load, on a lower base so that the distance between surfaces facing each other of them is changed in proportion to the load. CONSTITUTION:Outside end parts of a pair of elastic bodies 8 and 8 consisting of rubber are fixed to a substrate 1 in the diametral direction orthogonal to the lengthwise direction of a lower base 2. A disc-shaped upper receiving base 13 is fixed with the same center as the substrate on inside end parts of elastic bodies 8 and 8, and a lower face 15 of the receiving base 13 is allowed to face an upper face 16 of the base 2 a small gap apart from and in parallel with the face 16. Plural recessed and projecting stripes arranged in the lengthwise direction of the base 2 are formed at an equal pitch on the lower face 15 and the upper face 16, and centers of projecting stripes 18 and 19 of them are allowed to face centers of recessed stripes 20 and 21 of each other. When the load is applied onto the receiving base 13, elastic bodies 8 are bent, and an optical fiber 22 is constricted between projecting stripes 18 and 19 to cause minute behind deformation, and therefore, the light from one end 22a is reduced by the microbend loss and is emitted from the other end 22b. This emitted light is converted to an electric signal, and the magnitude of the load is detected by the change of the electric signal.

Title: Programmable controller
Inventor: TODA JITSUO
IPC: G05B19/02
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a programmable controller having a high response speed to the change of an input signal by catching the rise or fall of the signal change by a flip-flop FF. CONSTITUTION:The input signal of an input signal processing part 17 is set to the desired polarity by a polarity switching circuit 12. When an output signal showing an abnormal state is supplied to an FF14, the FF14 transmits this output signal to an interruption control circuit 16. A CPU 1 receives an interruption signal and discontinues temporarily the normal arithmetic processing action to specify the signal change of a controlled system that caused an interruption. Then the CPU 1 processes the abnormal state based on an interruption signal processing program set previously. An action inhibiting signal is outputted to the corresponding FF14 from an FF control circuit 15 with a controlled system that is not required to give a prompt response to the signal change. Thus the FF14 never works even with input of the output signal of an input circuit that is due to the signal change of the controlled system.

Abstract: PURPOSE:To conduct a horizontal output transistor (TR) completely by keeping k duty cycle of an output square wave of a horizontal oscillation stage to be proset value when a horizontal deflection circuit is operated at a horizontal scanning period longer than the shortest horizontal scanning period.
