IPC: B65G15/42
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for easily producing a toothed belt having small-pitched teeth. SOLUTION: The toothed belt, composed of tooth parts 2 which are installed plurally in the longitudinal direction and the surfaces of which are covered with a tooth cloth 1, a tension cord 3 buried on the back side of the tooth parts 2, and a canvas 5 buried in a back rubber layer 4 on the more back side than the tension cord 3, is manufactured.

Abstract: PROBLEM TO BE SOLVED: To correct the inclination of joint surfaces without using moving means, such as stages, and sensors, such as monitors and to eliminate the laboriousness of adjustment work by providing the joint surfaces with holes for attracting parts, sucking the air of these holes and attracting the contact surfaces with the mating part with one part. SOLUTION: A suction jig 4 is mounted at the part 1a and the part 1b is clamped by a jig 3 and the joint surface 2 is brought near to the joint surface 2 of the part 1a (1). After the parts 1a, 1b are brought near to each other, the part 1b is released from the jig 3. The air is sucked to the hole 6 of the suction jig 4 from the hole 5 formed at the joint surface 2 and the part 1b is attracted by the suction jig 4, by which the joint surfaces 2, 2 are brought into nearly tight contact with each other (2). The jig 3 is mounted attain at the part 1b and the suction is ceased (3). The paralleling of the joint surfaces 2, 2 with each other is ended in this step and if there is a need for moving a place, the joint surfaces are moved, the work to obtain alignment and optical coupling may be started with this position as an original.

Title: Hydraulic controller of non-stage transmission for vehicle
Inventor: KATO NOBUYUKI
IPC: F16H9/00
Filed: 1989-08-09
Abstract: PURPOSE:To improve durability of a hydraulic controller of a non-stage transmission for a vehicle by removing a check valve from a bypass oil path for exclusively supplying operating oil in a first line oil path to a secondary hydraulic cylinder at the time of slow acceleration. CONSTITUTION:During slow acceleration when a first spool valve 280 is positioned at accelerating side and a second spool valve 288 is positioned at flow rate suppressing side, operating oil in a first line oil path is supplied from a second output port 278d of a transmission direction change valve 262 exclusively through a second connection oil path to a primary hydraulic actuator. Then, when the first spool valve 280 is positioned at decelerating side, the second output port 278d of the transmission direction change valve 262 is shut by the first spool valve 280, resulting in shut of the second connection oil path. Thus the second connection oil path functions as a bypass oil path while it is not equipped with a check valve, thereby eliminating deterioration in durability caused by the check valve.

Title: Enclosure structure of electronic apparatus
Inventor: IIKURA KENJI
IPC: H05K5/03
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide enclosure structure of an electronic apparatus to easily unlock a cover for opening. SOLUTION: When opening in an enclosure 1 is closed with a cover 2, a lock-piece 6 is fitted into a lock-groove 5 of a catch 4. The cover is locked, a contact piece 7 exerting the catch 4 to the unlock-side by elastic deformation of the contact piece 7 and holding the catch 4 by a rib 8. The catch 4 is, therefore, not unlocked and the cover 2 remains fixed to the enclosure 1. When the cover 2 is opened, the center catch 4 on the cover 2 is exerted from an outside plate, and the cover 2 is bent. Then, when the catch 4 is inserted by a predetermined length into the opening of the enclosure 1, the catch 4 is unlocked from the rib 8, passing through under the rib 8 by elastic deformation from the lock-piece 6 to the unlock side, which is caused by elastic deformation of the contact piece 7.

Title: Exhaust of gas treatment device
Inventor: KISHI TADAO
IPC: G21F9/02
Filed: 1990-08-06
Abstract: PURPOSE:To ameliorate a heat balance as well as to simplify a device structure and reduce a handling cost of exhaust gas by expanding hydrogen gas absorbed in a hydrogen absorbing vessel adiabatically in order, manufacturing a batch of cooling water, and cooling the exhaust gas at a stroke. CONSTITUTION:When a hydrogen storage metal 10aa in a hydrogen absorbing vessel 11aa of a hydrogen absorbing unit 12a comes to a state of being saturated of absorption, it is selected to another hydrogen absorbing unit 12b. Then, it shifts to a process that hydrogen gas in the vessel 11aa so far made into the absorption saturated state is discharged to other hydrogen absorbing vessels 11ab, 11ac. Thus, such a hydrogen flow circuit, repeating these hydrogen gas absorption and discharge, is constituted, and high pressure hydrogen is adiabatically expanded in this circuit, through which a cold hydrogen gas is secured. With this constitution, low temperature cooling water is produced in a cold water heat exchanger 15, feeding a condenser 5, and exhaust gas out of an extractor 2 is effectively cooled at a stroke by this condenser 5. Consequently, the extent of suction efficiency of the exhaust gas in an activated carbon hold-up tower goes up, thus a radioactive damping effect of the exhaust gas is improvable.

Title: Failsafe mechanism of belt type continuously variable transmission
Inventor: MATSUURA KOZO
IPC: F16H59/46
Filed: 1988-08-20
Abstract: PURPOSE:To accomplish failsafe by engaging a clutch in the event of belt severance or enlargement of slip to cause the speed change ratio of a belt type continuous transmission to lie outside a specified extent, and performing transmitting via a power transmitting member. CONSTITUTION:When severance of a belt MC or enlargement of its slip has caused the ratio of the revolving speed of an input shaft MA of a belt type continuous transmission MD to that of its output shaft MB, i.e. speed change ratio, to lie outside of the specified range, it is sensed by a speed change ratio sensing means MG, and according to signal therefrom a clutch engaging means MH engages a clutch MF. Accordingly transmitting of power between the input shaft MA and output shaft MB is made detouring the belt MC, i.e. via a power transmitting member ME with the clutch MF interposed. Thus the failsafe function of belt type continuous transmission is enhanced.
