Title: Semiconductor device
Inventor: TOMINAGA TAMOTSU
IPC: H01L23/52
Filed: 1988-05-24
Abstract: PURPOSE:To obtain a highly reliable fuse function, by forming a cavity at least at the upper part or the lower part of a narrow region which is provided at a part of a wiring layer. CONSTITUTION:A wiring layer 13 has a narrow region 13A where the width is made narrow. A passivation film 15 comprises a PSG film which covers the wiring layer so as to form a cavity 14 on the narrow region 13A. Therefore, when a fusing current is made to flow through a wiring pattern 13 where the cavity 14 is formed, a wiring metal is fused at the neck-in region 13A which is formed in such a way that the wiring width becomes narrow. The metal expands in the cavity owing to surface tension so as to form a round shape. Thus, the wire is readily broken. In this way, wire breakdown readily occurs without damaging an insulating film at the upper part and a sealing resin 18. Thus the device effectively acts as a fuse.

Title: Fixed flow rate throttle valve unit
Inventor: YOKOTA HIDEKUNI
IPC: G05D7/01
Filed: 1979-09-27
Abstract: PURPOSE: To make it possible to prevent an intensive outflow accompanied by vibration, by providing a throttling passage having the inclined surface against movement of a throttle valve.  
     CONSTITUTION: A throttle valve 11 moves in accordance with pressure of a fluid, and keeps the flow rate constant by reducing the width of the throttling passage 17. The throttle valve seat 13 confronting with the throttle valve 11 is formed so that it has the inclined surface. The throttling passage is shifted from the opened state 17 to the closed state 18 as the throttle valve 11 moves. When the throttle valve 11 has passed through a perpendicular line of the inclined surface of the throttle valve seat 13, the subsequent amount of variation of an area of the throttling passage becomes the amount of variation of the throttle valve 11×Sinθ (provided that θ is an angle of the inclined surface). Namely, the amount of variation of the throttling passage against displacement of the throttle valve 11 is reduced, and even if the throttle valve becomes a state that displacement is caused by vibration, it is prevented that the flow rate is varied remarkably by vibration.

IPC: H02P7/29
Filed: 1986-06-02
Abstract: PURPOSE:To eliminate the need for a resistor for detection by limiting currents by using the ON-OFF duty of a switching element. CONSTITUTION:A DC motor M is controlled at constant speed by turning a switching element Q ON-OFF and changing the duty of the switching element. The duty is obtained by comparing and amplifying DC voltage Vf acquired by F/V converting an encoder signal transmitted over the DC motor and command voltage Vi and comparing them with triangular-wave oscillation voltage. ON signal of the switching element Q is integrated by an integration circuit, and converted into voltage Vc. When voltage Vc reaches reference voltage Vr or more, an output from a comparator IC1 reaches L, and an output from IC2 reaches H and the switching element Q is turned OFF. When voltage Vc drops, the output from the IC 1 reaches H, the output from the IC2 reaches L after a fixed time by the time constants of R5 and C2 passes, and the switching element Q is turned ON.
