A clutch for a transmission is provided in which a transmission case includes a first wall portion and a second wall portion that define a clutch housing chamber for housing a clutch outer, a clutch inner, a friction member, and an extension portion of a first gear shaft that extends from a shaft end portion of a second gear shaft, the clutch outer is supported on the first wall portion via a first bearing, and the clutch inner is supported on the through hole of the second wall portion, through which the first gear shaft extends, via a second bearing, and therefore, it is possible to enhance the coaxiality of the clutch outer and the clutch inner by supporting them on the transmission case independently from the first and second gear shafts, prevent the torque transmission capacity of the clutch from decreasing, and avoid the occurrence of judder.

Clutch for transmission

A rotation angle sensor providing excellent output characteristics is provided. The rotation angle sensor has a structure in which a ring-shaped permanent magnet provided so as to be rotatable integrally with a rotor connected to a member to be detected; magnetic flux gathering yokes surrounding the outer circumferential surface of the ring-shaped permanent magnet with a certain clearance being formed between the outer circumferential surface and the magnetic flux gathering yokes; and Hall ICsarranged in gaps between the magnetic flux gathering yokes, are arranged inside a casing formed by a casing body and a cover. In the casing body, a guide tube surrounding the outer circumferential surface of the ring-shaped permanent magnet is formed with a certain clearance being formed between the outer circumferential surface and the guide tube. The guide tube is made of a material having a linear expansion coefficient smaller than that of the casing, and the magnetic flux gathering yokes are fixed to the outer circumferential surface of the guide tube.

Rotation angle sensor

A movable contact point board provided with contact points is urged in a direction of being away from stationary contact points by return springs each having the same size and the same characteristic, and is arranged as opposed to the stationary contact points. Return springs have the respective ends for supporting locations in the movable contact point board which are away from each other as having the contact points in the movable contact point board therebetween and support heights of the return springs at the stationary side differ with each other by D. When a plunger equipped with a holding portion having a flat surface as a bottom surface presses the movable contact point board, the contact point in the movable contact point board gets in contact with the stationary contact point at an inclined posture. Thereafter, while the movable contact point board becomes perpendicular to the axial direction, a contacting point between the contact point in the movable contact point board and the stationary contact point varies to perform the wiping function.

Push switch

The present invention aims at achieving the object of keeping a contact housing portion liquid tight sealed and to improve the durability of a switch apparatus. A switch apparatus according to the present embodiment includes: a switch caseincluding a contact housing portiontherein and a shaft hole; a rodwhose outer flange portionis capable of axially abutting on and engaging with a periphery portionof a detecting plate; a first return springbiasing the rodin the direction opposite to protruding direction; a fixed contactin the switch caseand a movable contactwhich can reciprocally move between a position touching the fixed contactand a non-touching position; a diaphragmseparating the shaft holefrom the contact housing portionand being formed of rubber; a movable basesupporting the movable contactand abutting on the diaphragm; a second return springbringing the movable contactinto contact with the fixed contact; and a retention memberinterposed between the diaphragmand the rod, including an abutting portionfor abutting on the rod, and axially movably, but not rotatably supported with respect to the switch case

Switch apparatus

A conductive composition capable of producing a conductive coating with excellent flexibility and a high conductivity comparable to that of metallic silver, without using high temperatures as film forming conditions. The conductive composition includes a particulate silver compound and a binder, and optionally a reducing agent and a binder. Silver oxide, silver carbonate and silver acetate and the like are used as the particulate silver compound. Ethylene glycol, diethylene glycol, and ethylene glycol diacetate and the like are used as the reducing agent, and a fine powder of a thermosetting resin such as a polyvalent phenol compound, phenol resin, alkyd resin or polyester resin, or a thermoplastic resin such as a styrene resin or polyethylene terephthalate, with an average particle diameter from 20 nm to 5 &#x3bc;m is used as the binder. Furthermore, the average particle diameter of the particulate silver compound may be from 0.01 to 10 &#x3bc;m.

Conductive composition

A parallel axes type transmission including a first idle drive route and a second idle drive route for transmitting the relation of an input shaft to an intermediate shaft. The first idle drive route includes a one-way clutch capable of transmitting the rotation of the input shaft to the intermediate shaft only. The second idle drive route includes wet multiplate clutches for connecting gears rotatably mounted on the intermediate shaft to the intermediate shaft when engaged. Thus, the intermediate shaft is rotated at a first rotational speed through the first idle drive route and at a second rotational speed faster than the first rotational speed through the second idle drive route when the clutch is engaged.

Parallel axes type transmission having a plurality of idle drive routes

An object of the present invention is to provide a silver compound paste which can be easily applied without containing resin, and which produces a conductive film having a low electric resistivity by heating under conditions substantially equivalent to those in a conductive film containing a polymer type conductive paste. The present invention provides a silver compound paste containing silver oxide particles and a tertiary fatty acid silver salt.
