Title: Substrate inspecting instrument
Inventor: NAGARA YASUSHI
IPC: H01L21/66
Filed: 1986-02-19
Abstract: PURPOSE:To easily manufacture an inspection system for substrates and to shorten the inspection time by storing all signals outputted from specific output terminals of a substrate to be inspected, and deciding whether they are normals or not in order. CONSTITUTION:The substrate 12 to be inspected is provided with an input means for inputting a specific signal (a) for operating the substrate. Further, an analog signal storage circuit 35 and a digital signal storage circuit 30 are provided to store signals from respective output terminals which are detected by a detecting means connected to the output terminal of the board 12. Then, the signals (b) and (c) stored in the circuits 35 and 30 are compared with reference values predetermined according to the respective input terminals and a CPU 16 is provided to discriminate whether the output signals are normal or not. Consequently, when the CPU 16 operates the substrate 12 by inputting a prescribed signal (a) to the substrate 12, respective signals outputted from prescribed terminals of the substrate 12 are detected by a detecting means and all stored 35 and 30 regardless of the timing of the input signal and the CPU 16 discriminates whether or not the respective output signals are normal or not.

Title: Interface circuit
Inventor: MURAYAMA AKIHIRO
IPC: H03K19/018
Filed: 1991-02-28
Abstract: PURPOSE:To eliminate leakage of pulse to an analog circuit and to shorten pulse delay time by forming the configuration of a circuit in a differential output type, and using an interface transistor as a base-grounded one. CONSTITUTION:The output gates G3, G4 of logic are inputted to the emitters of transistors Q4, Q5 via resistors R6, R7. The bases of the transistors Q4, Q5 are connected to a reference voltage Vref in common, and the collecters to a power source Vcc via resistors R8, R9. Input voltages Vin4, Vin5 are set as the ones with negative phases mutually. Thereby, since neither the transistor Q4 nor the transistor Q5 are saturated, nor leakage of an input pulse signal to another peripheral circuit occurs, and since a base electric charge is not accumulated, no delay occurs in the response of the transistor.

IPC: G01M10/00
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To generate an accurate waveform by adding an input-compensating device consisting of a compensation function generator and a subtractor to a wave command signal generator and allowing the subtractor to subtract the signal of the compensation function generator from that of the wave command signal generator. SOLUTION: An input-compensating device 300 consisting of a compensation function generator 301 and a subtractor 302 is added to a wave command signal generator 110. The wave command signal generator 110 outputs a signal f(t) for enabling x1 at the connection point coordinates (x1 , y1 ) between a wave- making plate and a connection rod to make a movement expressed by x1 =f(t) to the subtractor 302. Also, the compensation function generator 301 outputs a signal g(t) for enabling x2 of the connection point coordinates (x2 , y2 ) between a linear way and the connection rod to make a movement expressed by a compensation term expression I (L: continuous rod, r: length of each wave-making plates) to the subtractor 302. The subtractor 302 outputs a signal expression II that is obtained by subtracting the signal g(t) from the signal f(t) to a motor 101 for drive.  More specifically, by adding the input compensation device 300 to the wave command signal generator 110, an accurate wave can be generated.

Title: Liquid chemical injector
Inventor: YAMADA KEIICHI
IPC: A61M5/152
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent tension from being generated in an elastic bag member as long as fluid is not injected to a fluid injection chamber by forming the fluid injection chamber in the inside by a tension imparting member and forming a liquid chemical filling chamber between the of the tension imparting member and the elastic bag member formed around the tension imparting member. SOLUTION: Inside an outer side balloon 3 for filling liquid chemicals, a different balloon 2 is disposed and air or water is injected to the inner side balloon 2 immediately before use. When the inner side balloon 2 is expanded by the air or the water, prescribed tension is generated to the outer side balloon 3 at the time of the most construction. Thus, since the outer side balloon 3 generates the tension immediately before the use, even when a keeping period becomes long, elasticity does not decline.

Title: Mf signal detecting circuit
Inventor: TADA TAKATOMO
IPC: H04M1/50
Filed: 1987-02-20
Abstract: PURPOSE:To eliminate need for an expensive microprocessor by using an envelope period detection means so as to detect a period of an envelope of an inputted MF signal, outputting it to a number detection means and using the number detection means to retrieve and read the number corresponding to the inputted period from the storage means.

Thus, the number of the PB signal is detected (that is, the input MF signal) corresponding to the period from the envelope period of the input MF signal. Thus, the circuit is simplified with less number of components and only one input port of the microprocessor 37 is enough. Thus, any expensive microprocessor is not required and the circuit cost is reduced.
