Title: Film thickness measuring device
Inventor: KITAMORI TAKEHIKO
IPC: G01B21/08
Filed: 1983-04-08
Abstract: PURPOSE:To make it possible to measure the thicknesses of an opaque film and a film resembling a substrate highly accurately, by directly contacting a piezoelectric converter, which detects an opto-acoustic signal to a sample, and analyzing the phase and the strength of the detected opto-acoustic signal. CONSTITUTION:A film 10 is formed on a substrate 9. A piezoelectric element 11, which detects an opto-acoustic signal, is directly contacted on the opposite side. When emitted laser light 12, whose strength is modulated periodically like pulses, is applied to the element 11, an opto-acoustic signal is generated. The strength and the phase of the signal are functions of the thickness of the film 10. In an actual device, the opto-acoustic signal 18 is sent to a lock-in amplifier 20, and the data of the strength and the phase are analyzed. Based on the results, the film thickness is measured by a microcomputer 21. Since the strength and the phase of the opto-acoustic signal are analyzed, the thickness of the opaque film and the thickness of the film, whose difference in physical constants with the substrate is small, can be measured accurately.

Title: Printed circuit board defect inspecting device
Inventor: TAKIZAWA HIDEO
IPC: G01N21/88
Filed: 1986-03-20
Abstract: PURPOSE:To achieve a higher inspection accuracy of a pattern defect, by forming an image of parallel beam fluxes as obtained from two or more collimators on a printed circuit board to detect fluorescence generated therefrom with the image formation. CONSTITUTION:Parallel beam fluxes R1 and R2 as obtained from collimator lens systems 13 and 14 and respectively reflected with flat mirrors 15 and 16 are reflected by respective flat mirrors 17 and 18. Thereafter, the beam fluxes are made incident into a primary mirror 19a of a Cassegrain mirror 19 and reflected by the primary mirror 19a and a secondary mirror 19b to form an image at the same point on the printed circuit board 6. Fluorescence generated from the circuit board 6 with the image formation forms an image on a CCD9 via a dichroic mirror 7 and a condenser lens 8. A signal generated from the CCD9 is applied to an inspection processing circuit through an pre-amplifier 10. Thus, a higher inspection accuracy is achieved with a greater illuminance of an exciting light.

Title: Input and output control system for electronic computer
Inventor: KANDA AKIRA
IPC: G06F13/10
Filed: 1985-03-27
Abstract: PURPOSE:To attain production of an input/output control program by using a communication window mapping control part which controls mapping with reference to a priviledged level table. CONSTITUTION:Input/output communication window pages 61 and 62 are allocated to input/output controllers 4a and 4b on a memory address space 6 respectively. Then the priviledged levels are given to the pages 61 and 62 in response to the degrees of importance of the corresponding input/output devices, e.g., 5a and 5b. These priviledged levels are stored in a priviledged table 8 within a communication window mapping control part 7 for each input/output device and controlled. The priviledged control of the input/output actions is possible independently for each input/output controller. Therefore, it is not needed to incorporate an input/output control program corresponding to the relevant input/output device as a part of a system program even in case an input/output device is added. this facilitates an easy check of an added input/output control program.

Title: Thyristor driving circuit
Inventor: NAKANO AKIHISA
IPC: H02M1/08
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To miniaturize a power circuit and to save power by making gate much current flow for the prescribed time of an initial stage in the driving of thyristor, executing a discontinuous operation, reducing gate current and operating the thyristor after the temperature of a thyristor element rises. SOLUTION: A gate circuit for turning of a triac 7 turns on a transistor 12 and therefore large gate current is supplied. Since gate current flows to the triac 7 during a disconnection operation when the kneading of a material is started, the triac can be turned on even in the severe environment of not more than -10 deg.C. Gate current which actually flows becomes that of 1/10 when it is turned on for 0.05 seconds and is turned off for 0,05 seconds as an average value. Even if a room temperature is not more than -10 deg.C, current flows in the triac 7 itself and therefore the temperature rises. The temperature of the triac 7 becomes not less than 30 deg.C after about one minute, for example. Thus, a transistor 13 is turned off and only the transistor 12 is turned on. Even if the supply of gate current is reduced, the triac 7 can sufficiently be turned on.
