Title: Buffer memory control system
Inventor: TONE HIROSADA
IPC: G06F9/38
Filed: 1978-12-22
Abstract: PURPOSE: To enhance the data process performance for the buffer memory device of the data processor of pipe line system by securing the independent separation between the instruction fetch buffer and the operand buffer and also securing execution of the operand store for both buffers.  
     CONSTITUTION: Operand buffer 3 and instruction fetch buffer 4 are separate from each other, and given the access by address registers 1 and 2 independently. While at the operand store time, the operand address is applied to registers 1 and 2, and the operand data set to store data register 5 is stored in buffer 3. At the same time, the operand data is stored in buffer 4 only in case the store address block exists within buffer 4. And in case the subsequent order is rewritten by the store instruction, the simultaneous buffer access is possible to both the instruction fetch and the operand fetch with prevention of the fact that the unnecessary data remains with  no renewal.

Title: Method of discharging inflation pressure of tire
Inventor: OSHIMA MASAKAZU
IPC: B60C23/00
Filed: 1991-06-29
Abstract: PURPOSE:To always control the air pressure of a tire so as to stably exhibit a high cornering force or the like by opening an air-sealing means overcoming a spring in a valve so as to discharge the inflation pressure of the tire when the internal pressure of the tire fitted on a wheel increases due to heat generation of the tire during running. CONSTITUTION:When the internal pressure charged in a tire fitted on a wheel is a predetermined value (or not greater than the predetermined value), a valve 1 maintains its air-tightness since the force of a spring 4 overcomes the internal pressure of an air seal chamber I. However, when the internal pressure of the seal chamber I increases excessively, a piston 5 is pressed upward so that a gap between a packing 3 and the annular surface 10 of the body 2 is opened so that the inflation pressure is discharged into the atmosphere through a passage 14. When excessive inflation pressure is discharged, the gap between the packing 3 and the annular surface 10 of the body 2 is closed under the action of the spring 4, the air tightness is held. Thus, the internal pressure of the tire fitted on the wheel is held at a predetermined value.

Title: Geared motor
Inventor: GOMI SUSUMU
IPC: H02K7/10
Filed: 1991-06-03
Abstract: PURPOSE:To transmit the rotation of a motor efficiently by a method wherein, when the motor rotates, a coil spring wound up by the rotation of a master moving member is wound tightly around a subsidiary moving member and connected with it to transmit the rotation of the master moving member to the subsidiary moving member. CONSTITUTION:When a switch 2 is closed, the pinion 1 and the gear 7a of a motor A is turned in a direction of an arrow and a master moving member 8, a coil spring 11, a resistance member 26 and sliding members 29 are also turned in the same direction. The sliding members 29 are expanded radially by a centrifugal force against the actuation force of an arm 30 and are brought into contact with a braking member 27 to produce a resistance. The contact resistance is applied to the other end 11b of the coil spring 11 and the one end 11a of the coil spring 11 is wound up by the master moving member 8. The diameter of the coil spring 11 is reduced and the coil spring 11 contacts with a subsidiary moving member 10 to transmit the rotary force of the master moving member 8 to the subsidiary moving member 10 completely. Thus a linking member 6 linked with a load (not shown) is driven through a transmission mechanism C and an output member B. If the motor A is stopped, the coil spring 11 is loosened and the master moving member 8 and the subsidiary moving member 10 are released. With this constitution, the rotary force can be transmitted and relieved with high efficiency.

Title: Inertia sliding starter
Inventor: EBIHARA KOUHEI
IPC: F02N15/06
Filed: 1981-10-09
Abstract: PURPOSE:To perform the early disengagement of a pinion and to prevent the over rotation of a motor, by providing an attraction holding board and an electromagnet on a unilateral clutch of an inertia starter then connecting in parallel with a DC motor and releasing the attracting force when the motor will be under noload after the starting. CONSTITUTION:Upon closing of a start switch 52, a unilateral clutch 25 will move axially together with a pinion 29 to contact against a stopper ring 40. During this period an engine will start to move the holding board 31 which is attracted to a magnetic circuit 43 and the unilateral clutch 25 is held together with the pinion 29 at the position geared with a ring gear 30. Upon starting of the engine, the load on a DC motor 21 will decrease abruptly thus to reduce the current. Consequently the current flowing through a coil 44 will also decrease to decrease the attracting force of an electromagnet 32. Since the holding board 31 is disengaged from the magnetic circuit 43 by the spring force of a pinion returning spring 34, the clutch 25 is returned to the original position to disengage the pinion 29 from the ring gear 30 and the motor 21 will continue the rotation under the noload state and will be stopped by the turning-off of the  switch 52.
