Title: Rear wheel steering device for motorcycle
Inventor: MATSUMURA KAZUNORI
IPC: B62K11/10
Filed: 1989-06-14
Abstract: PURPOSE:To prevent rolling of a rear wheel during linear running and to effect stable linear running by a method wherein the intermediate parts of link members on both sides are intercoupled through a second link member allowing only lateral rotation, and a relative width between two coupling points and relative movement in a direction extending perpendicularly to the direction of width are regulated. CONSTITUTION:By constraining the intermediate parts of a pair of link members 3 and 3 on both sides to each other by means of a second link member 6, the coupling ends, coupled to the rear wheel support member 2 side, of the link members 3 and 3 are held so that they are always kept at a laterally uniform ground clearance when a vehicle runs linearly. Thus, a rear wheel 5 is prevented from rolling during linear running, and stable running is always ensured. Since the second link member 6 laterally rotatably coupled to the link members 3 and 3 with a slight clearance therebetween, a proper roll angle is produced during cornering, and no influence is exercised on steering of the rear wheel.

Title: Tape tension control mechanism of magnetic recording and reproducing device
Inventor: TAKEDA HIDEKAZU
IPC: G11B15/43
Filed: 1984-07-20
Abstract: PURPOSE:To stabilize tape tension control by providing an attaching/detaching member winding a tension addition strip to a reel turntable of a magnetic tape reel and moving the strip against an energizing force to detach the said adding member from the reel turntable. CONSTITUTION:The tension addition band 15 is wound nearly over the entire peripheral of the reel turntable 14, one end of the band 15 is supported turnably to one end of a tension addition band winding arm 18 and the other end is supported turnably to a tension detecting arm 9 by a band support pin 17. On the other hand, if the tape tension of a magnetic tape 1 is lowered due to external disturbance, the tape tension detection arm 9 is turned by the energizing force of an energizing spring 12 and the tension addition band 15 is moved in the same direction. Thus, the tightening amount of the reel turntable 14 by the band 15 is increased and the tape tension of the magnetic tape 1 is kept constant. Thus, the control of tape tension is stabilized.

Title: Electric dust precipitator
Inventor: AIKAWA ISAMU
IPC: B03C3/66
Filed: 1979-11-19
Abstract: PURPOSE: To improve dust collection efficiency and eliminate the protection cover for preventing danger owing to multiple power sources and high voltage by dividing an electrode element group consisting of plural discharge electrode elements to a plurality of subsegments and applying different voltages to every subsegments.  
     CONSTITUTION: A discharge electrode element group 10 is so divided that there is one electrode element 11 per each of six subsegments. The subsegment positioned nearest the gas inlet side is connected directly to a voltage supply part 13 (support fitting 15) and the other subsegment are connected to said part 13 via resistance elements 12, respectively. In addition, the elements 12 having subsequently higher resistance values from the gas inlet side toward the outlet side are used. Hence, voltage is applied to the respective subsegments, that is, discharge electrode elements, in such a manner that they are successively lower stepwise from the gas inlet side to the outlet side. As a result, the applied voltage of each group apparently rises according to dust densities and dust collection efficiency η increases considerably.

Abstract: PURPOSE:To make control of a mixing head easy and a molding device inexpensive. CONSTITUTION:A first chamber 16 and second chamber 17 are connected with each other and a mixing chamber bent into an L-shaped state is formed. Injectors 31, 31 are fitted to the first chamber 16 by facing on the first chamber 16.

When the valve stems 33 are each moved to a discharge position, the raw materials are each discharged to the mixing chamber 15 through the raw material discharge port 38 and mixed up with each other by colliding with each other. When only the valve stem 33 of the one injector 31 is moved to the discharge position, one raw material alone is discharged to the mixing chamber 15. Hereby, one side liquid discharge wherein the raw material is discharged through the one injector 31 becomes possible.

Title: Method and device for locking column nut for molding machine
Inventor: UENO TOYOAKI
IPC: B29C45/17
Filed: 1982-08-31
Abstract: PURPOSE:To prevent loosening of column nuts during operation and hindrance in molding operation, by moving the moving member of cylinder, in the final stage for adjusting die clamping force, up to the moving limit and holding the member there. CONSTITUTION:The times required for moving a rod 16 by a pitch driving device is calculated and a push button for driving the pitch driving device is pushed by the required times in case of controlling die clamping force manually by using the pitch driving. A slight error may arise in some cases between the die clamping force developed by the times when the button is pushed and desired die clamping force, but if the error is within a permissible range, the power source of an electromagnetic clutch is held turned off while a ram part 18 is positioned at one moving limit, that is, while column nuts are positioned at the moving limit on the side where they are not loosened, thereby holding the effect of the magnetic clutch intact. The button is further pushed if the error is not within the permissible range.

Title: Optical fiber frequency modulator
Inventor: MASUDA SHIGEFUMI
IPC: G02B6/287
Filed: 1985-07-09
Abstract: PURPOSE:To make a device small-sized and light-weight and prevent break of fibers by attaching an ultrasonic vibrator to the surface in the vertical, horizontal, or lengthwise direction of a block. CONSTITUTION:A black point in the center of each fiber is the core, and a fiber 11 consists of a part 11a buried completely in a block 17 and a part 11a' cut partially on a plane 12 by shaving off and grinding the block, and a fiber 13 consists of parts 13b and 13b' similarly. Frequency modulation is performed between parts 11a' and 13b' of fibers. Since forces are applied in the horizontal direction of parts 11a' and 13b' of fibers when fibers 11 and 13 are bent, fibers are easy to break if these parts are cut in the horizontal direction; but the contacting plate and planes of bending directions including fibers are approximately parallel with each other and force does not act in the breaking directions of fibers because the block is shaven off and ground in the horizontal direction.

Abstract: PURPOSE:To improve corrosion resistance and running property by subjecting a roll coiling a magnetic recording medium of a substrate formed with a ferromagnetic metallic layer to a heat treatment in an atmosphere where oxygen and moisture exist and specifying the surface roughness and coiling tension at the time of coiling. CONSTITUTION:Slight spaces 13 are formed to respective stages of the magnetic recording media of the coiled roll 10 by adjusting the tension onto a base film 1 at the time of coiling and the tape-like magnetic recording media are held in multiple stages of proximity positions via such spaces 13. The roll is disposed in the atmosphere where the oxygen and moisture exist, by which the roll is heat-treated. The oxygen and moisture are uniformly infiltrated and diffused between the surfaces of the ferromagnetic metallic layers 12 of the magnetic recording media and the base films 1 in proximity to the front faces of the ferromagnetic metallic layers. The average surface roughness (Ra) of the substrate surface is, therefore, desired to be in a 0.001mum<=Ra<=0.05mum and the coiling tension T thereof to be in the following range: 1kg/mm<2>. The corrosion resistance and running property of the magnetic recording medium are thus improved.
