Title: Ac 2-line system contactless switch
Inventor: WATANABE YASUYUKI
IPC: H03K17/94
Filed: 1981-06-03
Abstract: PURPOSE:To protect an internal circuit from being damaged when excessive current flows by connecting a voltage detecting circuit to detect that a constant current circuit consisting of transistors and resistances operates. CONSTITUTION:At normal operation, a transistor TR9 maintains off status during the period a detecting signal (b) is ''L'' and current flows from an AC zero point into a load 3. When the load 3 is shorted, the voltage applied to both the ends of a resistance 15 is quickly increased and the base current of a TR8 starts to flow through a TR7, so that the base current of a TR6 is reduced. Since impedance between the collector and emitter of the TR6 is increased at that time, the voltage of a point (A) rises, current flows through a voltage regulating diode 12, the TR9 is turned on, and TRs 8, 6 are turned off. Thus, the TR6 can be protected from being damaged.

Title: Bearing member
Inventor: MATSUMOTO SHINICHI
IPC: F16C27/02
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a bearing member having reduced torque during turning, and reduced deflection to a load in a radial direction. SOLUTION: In a condition where a sliding member is mounted on a bearing member 1 being formed by integrally fitting a metallic reinforcing ring 2 into a rubber elastic body, and also forming plural ribs on a bearing slide surface, at least one of plural ribs formed on the bearing slide surface is slidly contacted with a sliding member, and at least one plural ribs is made non-contact condition with the sliding member. Consequently torque can be reduced because of the less contact surface between the bearing member and the sliding member, and moreover deflection can be reduced compared with a conventional sliding member to a load in a radial direction because of the staged changes of the sliding member from a contact rib to a non-contact rib.
