Title: Comparison differential relay
Inventor: MIYAKE YASUAKI
IPC: H02H7/045
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To isolate a transformer from a power system with a large earth capacity immediately after the occurrence of a fault, by ensuring that a trip signal is outputted from a comparison differential means when it is judged that the power system is not in inrush state or both primary current and secondary current are above respectively specified values. SOLUTION: When a trip signal is outputted from a comparison differential 3 and a non-lock signal is output from an OR circuit 24, an AND circuit 25 judges that an internal fault has occurred in a power system, and isolates a transformer 1 from the power system. If a trip signal is outputted from a comparison differential 13 when it is judged by an inrush judging device 16 that the power system is not in inrush state or it is judged by load judging devices 21, 22 that both primary current I1 and secondary current I2 are above respectively specified values, the transformer 1 is isolated from the power system. It is possible to isolate a transformer 1 even from a power system with a large earth capacity immediately after an internal fault occurs.

Title: Vibrator
Inventor: TADA KOZO
IPC: H03H9/09
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To provide higher shock resistance than that of a conventional vibrator by adopting a flexible structure with respect to impact in every direction for an inner lead of this vibrator. SOLUTION: A vibrator chip 7 is soldered to a pad 5 of an inner lead 8 and a thin plate spring is made up of a longitudinal spring 9 and a lateral spring 10. The lead is hermetic-sealed to a header 1 and consists of the inner lead 8 and an outer lead 2 to form airtight terminals. When impact in a direction of the arrow is exerted to the lead 8, the spring 9 is bent and the lead 8 is deformed as shown by broken lines. Even when impact in an opposite direction to the arrow is exerted to the lead 8, the lead is also deformed. Furthermore, when impact in a direction perpendicular to the arrow is exerted to the lead 8, the spring 10 is bent and the lead 8 is easily deformed. When impact in a direction perpendicular to this paper is exerted to the vibrator chip 7, the leads are deformed in a way that one lead is extended and the other lead is contracted.  Thus, the vibrator 7 sufficiently withstands a shock in directions that a conventional vibrator can't withstand.

Title: Pulley viscous damper
Inventor: NUMAJIRI SUSUMU
IPC: F16F15/16
Filed: 1993-03-12
Abstract: PURPOSE:To provide a pulley viscous damper which is compact and high in reliability by furnishing a pulley with a large ring groove formed from a front end surface and an inner shearing ehclosed with fluid free to relatively rotate in the ring groove of the pulley. CONSTITUTION:When an engine is started and a crankshaft 1 is rotated, a pulley viscous damper 16 is rotated with the crankshaft 1, and auxiliary machineries are driven through a belt suspended around each pulley groove 10a of the pulley 10. In the pulley viscous damper 16, when the crankshaft 1 has positive or negative acceleration during rotation, relative rotation is generated between the pulley 10 and an inside inner shearing 11 accordingly, and then shearing force works on silicon oil enclosed between both of them. Consequently, the pulley viscous damper 16 generates damping force and absorbs torsional vibration of the crankshaft 1. Additionally, as silicon oil is used as a viscous member, it is high in heat resistance and excellent in damping performance.

Title: Light axis control device for head light
Inventor: WATANABE HISAAKI
IPC: B60Q1/12
Filed: 1985-03-15
Abstract: PURPOSE:To reduce a gap between the light axis of a head light and a running direction of a car to improve safety, by composing the light axis of the head light variable in the horizontal direction, and manipulating the light axis of the head light responding to the steering angle and the car speed. CONSTITUTION:When a driver handles the steering, the steering angle is converted to a signal by a steering angle sensor 9 and the signal is delivered to a control 11. In the control 11, the running direction of the car is decided by that signal and a signal from the car speed sensor 10 at the time. At the same time, the variation amount of the light axis responding to the acquired running direction is computed and sent to a driving device 8 as a signal. Then the driving device 8 makes a head light supporting plate 13 rotate around an axis 12 depending on the signal. In such a way, the head light 6 is rotated horizontally to face its light axis in the running direction of the car. Therefore, the gap between the light axis of the head light and the car's running direction is reduced to a minimum, and safety is secured.
