Filed: 1981-11-12
Abstract: PURPOSE:To easily automate a changeover switch, by inserting a male optical connector, which has a light reflecting part at the tip, between faces butting to each other of a female connector, where tips of two optical fibers are butted to each other, through a spring. CONSTITUTION:A male connector is so constituted that a part or the whole of the light incident to a light reflecting part 1 is reflected and is led to a light incidence end face 2 and is emitted to an optical fiber 3. The male connector is inserted between faces butting to each other of a female connector, where optical fibers 3' and 3'' are butted to each other at a point 7, against springs 6'. Though the whole of the light propagated in the optical fiber 3' is led to the optical fiber 3'' before insertion of the male connector, the light propagated in the optical fiber 3' is reflected by the light reflecting part 1 and is propagated to the optical fiber 3 after insertion of the male connector. Thus, a changeover switch is automated easily.

Title: Friction engaging device of automatic transmission
Inventor: DOI JUNICHI
IPC: F16H63/30
Filed: 1990-07-09
Abstract: PURPOSE:To reduce a shock at the time of engagement by forming such a constitution that an effective pressure receiving area of a piston member is decreased in a speed change shift of small necessary engaging capacity while making pressing force switchable of the piston member to a plurality of steps by making the effective pressure receiving area variable of the piston member. CONSTITUTION:In a pressure receiving area of an operating chamber 50, a clutch K2 is set so as to obtain pressing force of a piston 30 having necessary engaging force in a speed change shift (that is, reverse shift) requiring engaging capacity most in the speed change shift, where the clutch K2 is engaged, when a line pressure is supplied to the operating chamber 50. A difference of the pressure receiving area between the operating chamber 50 and a reaction force chamber 60 is set so as to obtain pressing force of the piston 30 having necessary pressing force in the case of 4-speed (4th) when the line pressure is applied to this area (differential area). In this way, when the line pressure is supplied only to the operating chamber 50, necessary engaging capacity at reverse shift engaging time is obtained, and when the line pressure is simultaneously supplied to the reaction force chamber 60, too, a sufficiently necessary engaging capacity at 4-speed shift engaging time is obtained smaller than at reverse shift engaging time.
