Title: Method and apparatus for inspecting wiring pattern
Inventor: HASHIGUCHI YUJI
IPC: G01R31/10
Filed: 1987-04-13
Abstract: PURPOSE:To enhance working efficiency, by applying voltage between wiring patterns to detect a short-circuit area on the basis of the current flowing between the wiring patterns and applying a predetermined current to the short- circuit area to blow said area by fusing. CONSTITUTION:The voltage of a constant voltage source 16 is applied between adjacent wiring patterns 12 from connection terminals 14-1, 14-2 and the presence of a short-circuit area is detected on the basis of the presence of the continuity of a current by a microcomputer system 15. When the short-circuit area is detected, the voltage V of the power source 16 is applied between the terminals 13-1, 13-2 holding the patterns 12 therebetween to allow a current I1 to flow between the patterns 12. Herein, the current I1 has the relation composed of I1=V/(R1+R0+R4) (wherein R1 is the resistance of one of the patterns 12, R0 is the resistance of the short-circuit area and R4 is the resistance of the other pattern) and becomes the value almost equal to a rated current I. When the current I1 flows to the short-circuit area, since the hair like cross-sectional area thereof is minute, the short-circuit area becomes a spark state by a generated high heat to be blown by fusing.

Filed: 1982-05-31
Abstract: PURPOSE:To prevent copying from being disabled by continuing a copying operation by a control means instead of a means generating a fault at the generation of defective diagnosis. CONSTITUTION:Signal plates 62-64 are arranged on proper positions of a mirror board 61 in consideration of the moving speed of the board 61. Photointerrupters 65, 66 are prepared for an optical position detecting signal and an optical home position signal, respectively. When the photointerruptor 65 or 66 is failed, the failure is detected. If the photointerrupter 65 is failed, for example, the current position of the mirror board 61 is detected by the counted number of drum clock pulses generated from a photosensitive drum on the basis of respective distances between signal plates 62 and 63 and between 63 and 64 and the distance between both the ends of the signal plate 64 to control the flow of the copying paper. Consequently, the copying operation is prevented from being disabled.

Title: Magnetic recording and reproduction system
Inventor: YOSHINO KAZUO
IPC: G11B5/588
Filed: 1983-05-24
Abstract: PURPOSE:To detect a tracking error and to perform excellent tracking control by utilizing two pilot signals which differ in frequency, and the azimuth angle of a recording and reproducing head. CONSTITUTION:An analog signal is inputted as a recording signal to an input terminal 1 and converted into a digital signal by an A/D converter 3. A drum pulse, on the other hand, is inputted to an input terminal 2. The output of a recording amplifier 8 is connected to a head HA or HB constituting the recording and reproducing head HR through a switch 9 to perform recording. In this case, the signal is recorded on every two tracks at a different carrier frequency while the azimuth angle is different between adjacent tracks, and FM signals different in carrier wave frequency are reproduced from tracks on both sides of a track being reproduced and separated to detect a tracking error from their relative level difference. Namely, the FM signals themselves are utilized as pilot signals in this case, so optimum tracking control is performed easily without any control track onto a tape.

Abstract: PURPOSE:To simplify the device and to accurately adjust the width of a coating liquid by constituting the device in such a manner that the width of a slit is adjusted by changing the distance between the step parts of two liquid feed heads. CONSTITUTION:A slit 14 is formed between liquid feed heads 1 and 2 below cavity 6 while the two heads 1, 2 are held coupled by a clamp 5. A coating liquid 15 supplied in the cavity 6 flows downward by passing the slit 14 and is applied on a band-shaped body 16, such as paper or film. One edge part in the transverse direction of the slit 14 is formed by a step part 8 and the other edge in the transverse direction is formed by a step part 9 and, therefore, the width of the slit 14 is changed to adjust the width of the coating liquid 15 flowing down from the slit 14 if the head 2 is slid and displaced by releasing the clamp 5 and elongating or contracting a piston rod 13. The clamp 5 is tightened when the width of the coating liquid 15 attains an adequate value. The width of the coating liquid 15 is thus accurately and freely adjusted.
