Abstract: PURPOSE:To prevent an edge cleaning member from being partially worn by cleaning an edge while abutting the outer peripheral edge of a disk at a position deviated from a rotational center on the tip surface of the edge cleaning member by a prescribed amount. CONSTITUTION:In the state of abutting an edge E of a disk D to an edge cleaning member 10 in the range of width B, while rotationally driving an edge cleaning part 10 by a rotary shaft 11, the outer peripheral edge E of the disk D is cleaned by a brush by supplying cleaning liquid. At the time of cleaning, force F in a tangential direction is operated to the disk D by the rotation of the edge cleaning member 10. The vector of this force F is equipped with components such as a component F1 in a Y axis direction and a component F2 in an X axis direction. This component in the Y direction is operated in the same direction over the whole abutted part of the disk D to the edge cleaning member 10. Therefore, by the force of the vector component F1 to the disk D, the disk D is rotationally driven and automatically rotated during cleaning even without rotationally driving the disk D by a special means. Then, the outer peripheral edge E can be cleaned as a whole.

Title: Pneumatic tire
Inventor: KATAYAMA MASAHIRO
IPC: B60C11/12
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To improve traveling performance and irregular abrasion resistance on the ice road. SOLUTION: A plurality of sipe 20 provided with a main body section 20A straightly extending from a tread 19 to a sipe bottom section in the direction orthogonal to the tread 19 and in the cross direction of the tire and two branch sections 20B separated from each other from a middle section in the depth direction toward the sipe bottom section are formed in a block 18. When abrasion progresses, the branch sections 20B appear, fractionating the tread 19, which restrains block rigidity from increasing, as a result, the block 18 falls down suitably. Therefore, the edge of a siping 20 works at its maximum. In addition, when the edge length becomes long as a result of the appearance of the branch sections 20B, edge effect is further improved. The deterioration of performance on the ice road due to abrasion is thus restrained.

Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To control the delivery of a packaged body from a bagging and packaging machine onto a carry-out conveyor in a manner corresponding to the rotational angle of the conveyor in one direction. SOLUTION: When a conveyor 14 is turned in the direction A, the quantity of the rotational motion is stored in a controller 23 through a rotational angle detection element 20 engaged with a supporting point shaft 21. A clamp plate 29 at tips of parallel links 27, 28 supported by one frame base 26 carries a packaged body 13 between partitions 17 of a carry-out conveyor by the rotation of the links 27, 28. The controller 23 regulates the feed flow rate to a controlled actuator 37 fixed to the link 28, and controls the folding angle of an indirect part 36 of the other link 27, and thus, the packaged body 13 is transferred constantly parallel to the partition 17 irrespective of the torsional angle of the carry-out conveyor 14.

Title: Superluminescent diode element and its manufacture
Inventor: HOSOBANE HIROYUKI
IPC: H01L33/08
Filed: 1993-12-20
Abstract: PURPOSE:To provide a superluminescent diode element which can emit a large- level super luminescent light and a method for manufacturing it reliably. CONSTITUTION:A step structure with an inclination surface in the waveguide direction of light is provided on the surface of a substrate 1 and an active layer 5 at a region corresponding to an area on the inclination surface is formed thinly. Light cannot be guided easily on the active layer 5 and an effective reflection factor can be fully reduced, thus suppressing laser oscillation. Since a current non-injection part B does not absorb light for application light, a large-level superluminescent light can be obtained. A thin lamination structure can be obtained with a single MBE growth, a window structure with a larger prohibition band width than that of the active layer 5 can be easily manufactured, thus obtaining an improved re-growth interface without any need for re-growth process onto GaAlAs layer with a large Al composition.

Abstract: PURPOSE: To perform control with improved responsiveness without lowering the reliability of data by providing a second transmission activation means for writing prescribed transmission data at an optional point of time before starting the reception of the data after ending the transmission of the data corresponding to a command from an outside and commanding the activation of a data transmission means. CONSTITUTION: In a first microcomputer 4, when a CPU 4c executes 'DMA reception activation,' the output of a permission signal output terminal RTS indicates input permission and data input is made possible through a data input terminal SiN. A DMAC 4d writes the data received through the data input terminal SiN in the prescribed area of a RAM 4b, and when all the write is ended, DMA reception completion interruption signals are outputted to the CPU 4c and the output of the permission signal output terminal RTS indicates input inhibition. When the CPU 4c executes the 'DMA reception activation' again, the DMA 4d outputs the data through a data output terminal SOUT.
