Title: Laminated electronic part and its production
Inventor: TSUJIKU KOICHIRO
IPC: C03C3/062
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To eliminate such troubles in conventional ion-exchanging process that a glass element should be covered with a specific heat resisting coat, and this causes troublesome works and makes the process expensive, and when plural points are ion-exchanged by one ion-exchanging, all the amounts of ion-exchanges at the ion- exchanged points become same to each other and a unit having different ion-exchanged amounts are not producible by one ion-exchanging. SOLUTION: A glass element obtained by partially integrating an ion-exchanging part consisting of glass having different ion-exchanging performance from a base glass onto the base glass is dipped into a molten salt so that ions in the base glass and/or in the ion-exchanging part are selectively ion-exchanged with ions in the molten salt. The ion-exchanging performance in the ion-exchanging part may be higher or lower than that in the base glass. Further, it is possible that plural ion-exchanging parts are formed, and the ion-exchanging performance in some ion-exchanging part is made different from that in another ion-exchanging part regarding an ion-exchange concentration or the kind of ion. When the ion-exchanging performances in ion- exchanging parts are made different regarding the kind of ion, it is necessary for the molten salt to contain plural kinds of exchanging ions.

Title: Driving force transmitting device
Inventor: TANIGAWA YUKIHIRO
IPC: F16D43/284
Filed: 1990-03-15
Abstract: PURPOSE:To surely transmit torque for the driven side to a normal torque transmitting section as well as to reduce torque to be transmitted when torque is transmitted reversely by forming on the side surfaces of a rotor with grooves which are obliquely extended from one side of its rotating direction to the other side of it while viscous fluid is being allowed to flow therein. CONSTITUTION:On the both side surfaces of a rotor 14 groove sections 14c are formed which are inclined at specified angles to the longer direction in such a way that a wide width section 14d1 is long in length at the pressing end surface 14d for normal rotation side with the opening 14c1 of the groove 14c shortened, and the entire section is however made to be the opening 14c2 of the groove 14 at the pressing end surface 14e for the reverse rotation side, and the rotating direction at the time of normal torque rotation where No. 1 propeller shaft 25 is thereby high in revolution, is set to the side of normal rotation, and the rotating direction at the time of reverse torque transmission is therefore set to the side of reverse rotation. When the rotor 14 is rotated to the normal direction, pressing force of viscous fluid to the direction of an arrow head a1 is greater, moreover, the amount of leakage to the direction of an arrow head a2 is less while high pressure is being built in a hold-up chamber R2. On the contrary, a reverse phenomenon happens at the time of reverse rotation, torque to be transmitted thereby becomes high at the time of normal torque transmission, bu becomes extremely low at the time of reverse torque transmission.
