Title: Low noise tyre
Inventor: KAGAMI KIICHIRO
IPC: B60C11/11
Filed: 1984-09-03
Abstract: PURPOSE:To provide effective interference with noise of a specific frequency range that are attributed to lateral grooves so as to attain suppression of noise by arranging slots having specific length in the specified positions with respect to the lateral grooves. CONSTITUTION:Four longitudinal grooves G1, G2, G3 and G4 extending in the circumferential direction of a tyre are arranged on the tread thereof. Each of the longitudinal grooves has slots 2 each open at one end thereof to related groove, internal lateral grooves 3 each connecting adjacent longitudinal grooves to each other, and side lateral grooves 4 communicating the side longitudinal grooves G1 and G4 each with the end part of the tread. A distance Ps from the center line of each of the slots to that of each of the lateral grooves is determined within a range of (n+1/2)XV/900-V/(4X900)<Ps<=(n+1/2)X1/900+ V/(4X900). (V stands for car speed expressed in Km/h and n is an integer selected among 0, 1 and 2.) As a result, the wavelength of frequency created from the slots will then be differed from that of frequency created from the lateral grooves so that the effect of cancelling pressure waves of noise each other by the interference therebetween can be expected.

Title: Bus conflict circuit
Inventor: KOBAYASHI HIROKI
IPC: G06F13/362
Filed: 1990-07-16
Abstract: PURPOSE:To always ensure the accesses of other conflict participant devices after a prescribed guard time even though they are beaten in the conflict by outputting a guard signal through a specific device that is treated with preference among plural participant devices when the conflict of accesses is controlled with use of an answer signal showing the bus conflict control result. CONSTITUTION:A preferential device 51 and an ordinary device 52 are stored in a bus 3 as the conflict participant devices and can have accesses to a common memory 6 via the bus 3 with the mutual conflict. The device 52 has the lower priority than the device 51. Thus the device 51 always has the high priority than the device 52 and is never beaten by the device 52 in the accesses to the memory 6. Furthermore the device 51 outputs a guard signal GAD to a bus conflict control circuit 4 through the output 10 at an access to the memory 6. Thus the device 51 can acquire the access preference right after a prescribed time.

Title: Perpendicular magnetic recording device
Inventor: HIKIJI SHUICHI
IPC: G11B5/127
Filed: 1986-08-07
Abstract: PURPOSE:To always obtain a stable reproduced output signal even in case of wear in the front end side of a main magnetic pole, by moving the main magnetic pole toward a recording medium in accordance with the reproduced output signal value due to a perpendicular magnetic recording head so that this reproduced output signal value is a certain value. CONSTITUTION:The reproduced output signal is reduced according as spacing between a main magnetic pole 13 an a recording medium 17 is increased because of wear of the front end part of the main magnetic pole 13 in the reproducing operation. This reduction is detected as the difference between the reproduced output signal and a reference signal by a differential amplifier 21. If this difference occurs, a head driving device 18 is operated by a head driving circuit 19, and only parts of a soft magnetic material 15, the main magnetic pole 13, and a main magnetic pole supporting material 14 in a vertical magnetic recording head are pushed in toward the recording medium 17 by a proper extent. They are pushed in until the reproduced output signal from a coil 10 coincides with the reference signal, and spacing between the main magnetic pole 13 and the recording medium 17 is reduced. Thus, the level of the reproduced output signal is always kept at an optimum certain value even in case of wear of the main magnetic pole 13.

Title: Winding device for cover film of taping electronic part
Inventor: ASAI KOUICHI
IPC: B65H41/00
Filed: 1992-06-19
Abstract: PURPOSE:To provide a cover film winding device which can release the function of a one-way clutch to check the reverse rotation of a winding reel for winding a cover film for taping electronic parts. CONSTITUTION:When a winding reel 104 is rotated in its winding direction, the inclination of a roller 130 makes an outer ring 132 move in a direction where a gap for sandwichedly holding a roller 130 between the outer ring 132 and a supporting shaft 108 becomes wider to make the rotation of the winding reel 104 allowable. When the winding reel 104 is reversely rotated, the outer ring 132 intends to move in a direction where the gap for sandwichedly holding the roller 130 becomes narrower, but can not move in such a way, and the rotation of the winding reel 104 is therefore checked. When the projecting part 150 of an outer ring guide collar 144 is pushed to move the outer ring 132 in a direction where the gap for sandwichedly holding the roller 130 becomes wider, the winding reel 104 can be rotated even in a reverse direction. When a plate-shaped member is engaged in an engaging groove 166 to push the projecting part 150, a reverse rotation checking function can be kept in its released state.

Therefore, thickness of the blade 3 can be thined and lightened either. Likewise, during damper closing, these support plates 41a and 41b arranged inside the blade support frame 2 act as straightening vanes with a gas running past the duct 40.
