Title: Automatic adjusting device of clutch
Inventor: NAKAO AKIHIRO
IPC: F16D23/12
Filed: 1987-11-07
Abstract: PURPOSE:To keep a satisfactory working condition of a clutch continually by providing such constitution as making automatic position adjustment of a clutch release lever according to abrasion of a clutch disc and automatically compensating the elongation of a clutch cable. CONSTITUTION:Even if any abrasion is caused in a clutch disc 4, a diaphragm spring 9 can be elastically deformed automatically in the direction of spring force action according to the abrasion. Thus, a sufficient pressing force from the diaphragm spring 9 always acts on the clutch disc 4 to prevent slipping in the clutch 1. On the other hand, if an elongation is caused in a cable 16 for connecting the first shaft 17 to a clutch pedal 10 as a motion transmitting mechanism 11, the sag of the cable 16 is absorbed by the sliding motion toward the energizing direction of the first shaft 17, so that the tension in the cable 16 is always maintained constant by automatically adjusting the length of the cable 16. Consequently, the working condition of the clutch 1 can be always maintained satisfactorily.

Filed: 1993-11-11
Abstract: PURPOSE:To obtain the subject cleaning member which can meet the quality requirements such as appropriate hardness, low permanent strain, low it resilience and further, durability to high temp. and high humidity, etc., by using a specific urethane elastomer as the material of the member. CONSTITUTION:A urethane elastomer obtained by allowing a polyester polyol produced by subjecting epsilon-caprolactone to ringopening polymerization using 2,2-dimethylpropanediol as the polymerization initiator and has an average molecular weight of 500 to 5000, to react with a polyisocyanate and curing the resulting prepolymer is used as the material of the cleaning member. At this time, when the average molecular weight of such polyester polyol is <500, the reaction product is hardened before completing the molding due to the too high reaction rate at the time of performing the curing (crosslinking) reaction by adding a polyisocyanate and a curing agent. On the other hand, when the average molecular weight of the polyester polyol is >5000, the effect of using neopentyl glycol (2,2-dimethylpropanediol) as the polymerization initiator is diluted.

Abstract: PURPOSE:To provide the molding technique with which both slipping of bonding wire by resin and the vibration of a work in vertical direction can be prevented. CONSTITUTION:A gate 38 is formed in the direction toward the radial center of a wire in a cavity 40, and a press-pin 5 is provided on the opposite side of the gate 38 pinching a work 24 in such a manner that the work 24 is supported.

The work 24 is going to be vibrated by the collision against the work 24 of the resin 47, but as the work 24 is pressed by the press-pin 45, the vibration can be prevented. Also, the air of the cavity 40 is expelled completely through an air vent 46.
