Title: Manufacture of high-melting-point metal gate electrode and inverted t-shaped high-melting-point metal gate
Inventor: FUERUNANDO DOORIINZU
IPC: H01L21/225
Filed: 1993-06-01
Abstract: PURPOSE: To provide a method of manufacturing an MOS transistor, having an inverted T-shaped high-m.p. metal gate. CONSTITUTION: This gate comprises a main CVD W layer 14A and lower sputtered W layer 16A, extending from the bottom of a CVD part to the outside, so that the gate section becomes like an inverted T-shape.

Filed: 1988-05-27
Abstract: PURPOSE:To keep a set feeding pitch even at the time of sewing thick machining cloth or one having difference in level and enable a pattern selecting operation at all times by restraining an engaging member with a restraining member when feeding teeth are transferring the machining cloth, while oscillating a pressing link against spring force accompanying the separation of a cam follower from a feed cam at the time of selecting the feed cam by means of a pattern selecting mechanism. CONSTITUTION:When feeding teeth 4 are feeding machining cloth 3, since an oscillating board 69 and a pressing link 63 are revolvingly energized downward centering around a pin 65 due to the spring force of a spring member 71, the engaging portion 56a of an engaging member 56 is pressedly energized by means of the elastic body 67 of a restraining portion 63c to restrain the revolution of the engaging member 56, i.e., a feed adjusting device body 53. At the time of executing the selection of patterns, the oscillating board 69 and pressing link 63 are oscillated upward against the spring force of the spring member 71 due to the upward oscillation of an operating board 38 via a linking rod 72, without pressingly energizing the engaging portion 56a of the engaging member 56 by means of the elastic body 67 of the restraining portion 63c, to release the restraint of revolution of the engaging member 56, i.e., the feed adjusting device body 53.

Title: Method for measuring vibration and noise of gear in gear-vibration-noise testing machine
Inventor: MURANAGA KOJI
IPC: G01H17/00
Filed: 1990-05-23
Abstract: PURPOSE:To shorten the measuring time to a large extent by setting the sequence of the vibration-noise measuring method of gears which are intermeshed, driven and rotated with a gear-vibration-noise testing machine at the specified sequence. CONSTITUTION:At first, a driving motor 3 is rotated. The rotation of a gear 1 on the driving side is kept at the constant rotating speed in a low-speed rotation region (b). The signal corresponding to the intermeshed rotation of the gear surface on the driving side is separated from the signal which is detected with a vibration detector 10, and good or bad is displayed. The acceleration is applied so that the number of rotations of the gear 1 reaches about 3,000r.p.m. after about 18 seconds. The noise vibration generated in the range of a high-speed rotation region (a) at this time is measured with the detector 10. The signal caused by the intermeshed rotation of the gear surface on the driving side is separated from the signal in a measurement setting part 12. The signal is compared with a preset determining level, and good or bad is displayed. Then, a gear 5 on the driven side is rotated in the reverse sequence, i.e. at a high speed (c) at first, then at a low speed (d), and good or bad is determined. The time can be saved to a large extent by the change in sequence.

Title: Phase demodulator circuit for ultrasonic detection system vortex flowmeter
Inventor: WADA SHIYUNICHI
IPC: G01F1/32
Filed: 1978-10-24
Abstract: PURPOSE:To realize a wide-angle phase modulation by dividing both the ultrasonic oscillation frequency signal and the ultrasonic reception signal by the divider and then supplying these signals to the phase comparator. CONSTITUTION:The oscillation signal of ultrasonic oscillation circuit 6 is 1/N-divided by divider 13 to be supplied to voltage control phase deviation circuit 7. Thus the phase deviation angle of circuit 7 is lowered down to 1/N. At the same time, the phase synchronous loop is formed with phase comparator 9, circuits 6 and 7 plus loop filter 10, and the synchronization is secured for the output of circuit 7 with the ultrasonic reception signal to deliver the phase modulation output through output 1. On the other hand, the ultrasonic wave sent from ultrasonic oscillator 4 receives the phase modulation via the Karman vortex 3 and is then received at ultrasonic receiver 5 to be supplied to phase comparator 9 after 1/N dividion via divider 12. The phase difference between the 1/N division waves equals to N times as much as the phase difference of the basic frequency. As a result, the phase range to be phase- demodulated in a high linearity can be expanded to N-fold to secure the output through output 2 and via LPF11.

Title: Printing roller
Inventor: SHIGA SHIYOUJI
IPC: B41F13/11
Filed: 1979-10-12
Abstract: PURPOSE:To provide an electroformed roller which has excellent workability and a long printing life by electrodepositing copper from a copper pyrophosphate bath onto a cylindrical substrate, in the printing roller used for gravure printing or the like. CONSTITUTION:A layer of copper having a thickness of about 100-500mu is electrolytically deposited from the copper pyrophosphate bath onto the surface of the substrate such as a cylinder of cast iron. In this case, the electrodeposition reaction can be promoted and a harder copper layer can be electrodeposited by adding organic salt, such as potassium oxalate, potassium nitrate, mercaptopyridine thiazole, 4-phenyl-3-thiosemicarbazide as additive to the bath. Since the copper deposited from the copper pyrophosphate bath has fine crystalline structure and does not soften easily, it is excellent in workability and durability.
