Title: Method of forming molybdenum resistor in superconductive integrated circuit
Inventor: JIYON KUSABIA PURIZUIBIZU
IPC: H01L27/18
Filed: 1990-05-24
Abstract: PURPOSE: To increase the yield by etching a molybdenum film on a titanium film to form a resistor utilizing that the intermetallic interface between titanium and molybdenum provides an effective etch-stop. CONSTITUTION: A titanium film 16 is formed on a superconductive film 12 and an exposed support 20, and a molybdenum film 10 is formed on the film 12 to form an etch-stop interface 22. Then, a patterned resist film is deposited on the molybdenum film 10 to expose a part of the molybdenum 10, and then etching is carried out to define a molybdenum resistor and at the same time to expose a part of the etch-stop interface 22, and it is oxidized to form the molybdenum resistor. The etch-stop interface 22 protects the superconductive film 12 and any layer under it to provide a large processing margin when the etching is carried out. Further, zirconium and/or hafnium can be used instead of titanium. Thus, both of the yield and the microwave characteristic can be improved.

Abstract: PURPOSE:To allow a pilot to adjust a speed over confirmation and operate an equipment at an invariably excellent fuel rate, and to save fuel by providing a speed sensor, fuel flow rate sensor, fuel rate arithmetic circuit and its storage circuit, and display device for displaying the fuel rate. CONSTITUTION:The speed of the transportation equipment is detected by the speed sensor 10 and the fuel flow rate is detected momentarily by the fuel flow rate sensor 16; and their outputs are inputted to an arithmetic circuit 14 to calculate the fuel rate of the speed and fuel flow rate. Then, stored fuel rates corresponding to respective speeds are displayed on the liquid-crystal display device 20 in the form a correlation curve A. When the environments are the same, the correlation curve A does not vary, so the momentary fuel rate displayed at a point A' is compared with the curve A. Consequently, the pilot judges whether current control is efficient or not at a look and performs the control at a good fuel rate to save the fuel.

Title: Diagnostic device for control system
Inventor: EZOE MITSUHIKO
IPC: G05B23/02
Filed: 1979-10-22
Abstract: PURPOSE:To exercise a supervision over whether a control system is abnormal or not with simple constitution, by detecting a corrected controlled variable and then by judging whether this detected contrlled variable or its change rate is within preset range or not. CONSTITUTION:For knocking control over a car engine, air sucked in engine 6 is measured by air flowmeter 2 and mixed in suction manifold 4 with fuel from fuel injection valve 5 before being distributed to respective combustion chambers of engine 6. The best ignition point of engine 6 is detected by knocking sensor 19, whose output is applied to microcomputer 1, which performs operations on the basis of an ignition point pattern at the point to find the best ignition point. Whether the value or change rate of the best ignition point is within the range preset in memory device 18 respectively is judged; when it is within the range, the control is carried on by considering the judgement and correction to be possible and when not, an alarm is generated by alarm device 25 to stop the operation of the control system, thereby changing the control over to fixed control for a constant amount.

Title: Recording and reproducing device
Inventor: HASHIMOTO NAOKI
IPC: H04N5/225
Filed: 1987-05-29
Abstract: PURPOSE:To eliminate unnecessary vibration and noise by extracting a natural vibration spectrum of a recording and reproducing device, generating a new frequency spectrum to cancel this vibration spectrum and recording a bit of sound information via a filter of that frequency spectrum. CONSTITUTION:The vibration being generated from the device of its own is mixed with the sound information from the external and then recorded in the form of the frequency spectrum into a RAM 14. Only the spectrum components generated inherently from the device are extracted from these signals by an arithmetic circuit 15 with, e.g., a soft ware having algorithm to find the average, and the frequency spectrum for cancellation of these components is computed to be sent out to a digital constitutive filter 16. Thus, by means of the digital constitutive filter having the spectrum for cancelling the natural spectrum generating from the device of its own, the unnecessary vibration and noise are eliminated without deteriorating the sound information to be taken in quality and quantity.

Abstract: PROBLEM TO BE SOLVED: To provide the wafer treatment unit by which a wafer is extracted from a cassette and the wafer is carried to a wafer treatment section without elevating/lowering the cassette. SOLUTION: The treatment unit is provided with a base plate 11 on which cassettes C in a standstill state are placed. A wafer W is extracted from a cassette C by elevating/lowering an indexer carrier unit 30 movable along the base plate 11. The wafer W is carried up to a substrate delivery position P while being placed on a support pin of the unit 30. After a wafer alignment mechanism mounted on the unit 30 aligns the wafer, the support pin is elevated to lift up the wafer W to a height at which the wafer W is delivered to a process carrying unit 21. The process carrying unit 21 receives the wafer W on the support pin and carries the wafer W to each of treatment units 231 , 232 , 241 -24 . Since the cassette C is not elevated/lowered in the extract and carrying process of the wafer W, dust production resulting from vibration of the cassette C is prevented.

Abstract: PURPOSE:To assuredly prevent occurrence of an accident due to sticking to a servomotor, a sterm valve, and so on, by providing same with a monitoring device which mechanically monitors occurrence of a sticking to the servomotor and so on in order to provide an annunciation signal. CONSTITUTION:When a piston 4 of a servomotor follows accurately the operation of a pilot valve 1, no limit switch operates at an intermediate position of the piston 4 so that electric current does not flow through an annunciator 14. If a steam valve 7 stickes to fail to follow the pilot valve 1 when it is controlled to further open from an intermediate open position thereof, only the pilot valve 1 moves a predetermined stroke in the opening direction from its intermediate position in which it closes an oil hole 16. Accordingly, only a limit switch 10a on the full open side of the pilot valve 1 operates to close its contact A and open its contact B. When this condition continues for a predetermined period of time, a timer 13 operares so that electric current flows through the annunciator 14 which thus issues an annunciation.
