Title: Keyboard for musical instrument
Inventor: KIHARA TSUTOMU
IPC: G10C3/12
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To improve the sliding property and wear resistance of a busing cloth so as to improve its durability by coating the bushing cloth, made of wool and bonded to the inner side face of a pin hole of a keyboard body, with fluororesin. SOLUTION: A balance pin hole 3 is formed from a keyboard body 2 to an intermediate seat plate 6 in such a way as to vertically pierce them. Bushing cloth 4 is bent in L-shape along the upper face of the intermediate seat plate 6 from each inner side face of a guide oblong hole part 3b of the pin hole 3 and bonded with a thermoplastic resin adhesive. The bushing cloth 4 is formed of rectangular wool cloth coated with fluororesin. The busing cloth 4 is manufactured by impregnating raw cloth knitted with wool fiber, with a fluororesin aqueous solution, for instance. Thus fluororesin is a perfluoroacrylic alkylate copolymer, for instance.

Abstract: PURPOSE:To form different thickness gate oxide films without causing field oxide film thickness to be decreased by successively removing a non-oxidizing from that on a transistor formation region where a gate oxide film is formed thicker and subjecting the same to thermal oxidization every such removal, and forming a plurality of the transistor formation regions of reduced film thickness. CONSTITUTION:A field oxide film 5 for defining a plurality of transistor formation regions is formed on a semiconductor substrate 1, and non-oxidizing films 4A, 4B1, 4B2 are successively removed from those on the transistor formation region 8 where a gate oxide film is formed thicker and subjected to thermal oxidation every such removal. Hereby, a plurality of the transistor formation regions each having gate oxide films 9 of reduced thickness are formed successively. Accordingly, there is eliminated an oxide film etching process of removing part of the gate oxide film upon forming the different thickness gate oxide films 8, 9 on a plurality of the device formation regions on a semiconductor substrate 1. Thus, the field oxide film 5 for inter-device separation is not made thinner by such an etching process, so that any inter-device leakage current is prevented from being generated to make the inter-device complete.

Abstract: PURPOSE: To perform a route search in which traffic restriction information from a starting place to a destination is taken into consideration by determining the existence of traffic restriction in the vicinity of a vehicle position on the basis of traffic restriction information stored in a memory and setting a position in which traffic is not restricted as the starting point of a route search. CONSTITUTION: A control circuit 2 selects a route searchable road close to 1a vehicle position detected by a current-place detection device 1 and reads node information on the road from a map storing memory 7 to select node information located in the travelling direction. When traffic is not restricted in both directions in the vicinity of a node on a selected road, the selected node is set to the starting point of a route search. However, when a vehicle is not on a route searchable road, the starting point of a route search is set on the route searchable road in the periphery of a vehicle position. When traffic is restricted in both directions, the starting point of a route search is set on a road in which traffic is not restricted in the vicinity of a vehicle position.

IPC: B23D33/08
Filed: 1982-06-03
Abstract: PURPOSE:To simplify construction of a device, by integrally forming a cutter and a material supplier of the long scale bar material cutting device used for a preceding process of hot forging. CONSTITUTION:If a bar material 1 is fed to a prescribed place via a guide roll 12, bottom feed roll 11 and a retaining roller 2, a cylinder 4 operates to lift the roller 2.

Abstract: PURPOSE:To prevent a cylinder from its thermal deformation and scuffing, by forming piston rings by resin of tetrafluoroethylene, polyamideimide, etc. and adjusting the surface pressure to a level of 10kg/cm<2> or less, with the internal surface of the cylinder to roughness of 4muRz or less. CONSTITUTION:A top ring 2, second ring 3 and an oil ring 4 are assembled into ring grooves of a piston 1, and expanders 5 are mounted to a back face of each ring, adjusting its surface pressure respectively to, for instance, 10kg/cm<2>, 0.9kg/ cm<2> and 4.2kg/cm<2>. A cylinder is made of cast iron, and its internal surface is formed to about 2-3muRz roughness. The piston ring is made of heat resistant and wearing resistant material such as polyimide resin, polyamideimide resin and tetrafluoroethlene. In this way, emission of blow by gas and scuffing can be prevented by enabling the piston ring to sufficiently follow the cylinder even if it is thermally deformed.

Title: Crank press
Inventor: KAMIIDE TAKUO
IPC: B30B1/26
Filed: 1985-05-01
Abstract: PURPOSE:To permit the easy loading and taking of a material into and out of dies without increasing the torque of a rotating system by using a pair of upper and lower links to constitute a connecting rod which connects a crank shaft and slider and putting the upper and lower links into a straight state at the point of the pressurizing time. CONSTITUTION:An oil pressure is generated on the cylinder root end side of a cylinder device 15 to push out a piston 10 and a piston rod 9. The upper and lower links 3, 6 are thereby fully extended to approximately the straight state and the slider 8 at the bottom end of the lower link is lowered at a large distance. The slider 8 executes a pressurization operation at a stroke 2e when the crank shaft 1 is rotated in this state. Since the links 3, 6 are held in the straight state, large reaction is not exerted to the piston rod 9. The oil pressure is generated on the opposite side of the device 15 at the point of the time when the crank part 2 passes the bottom death point and pressurization operation ends. The rod 9 is then contracted, by which the links 3, 6 are bent to a chevron shape and the slider 8 is raised to return to the upper limit home position.

Title: Carrier controller for recording disk signal detecting means
Inventor: SENOO TOSHIO
IPC: G11B9/06
Filed: 1987-04-18
Abstract: PURPOSE:To ensure the stable control for carrier of a signal detecting means even in such a case where a signal detecting part is unable to detect accurately a tracking signal out of a disk, by interrupting the application of the tracking signal to carrier control of the signal detecting means when a rubbing pressure exceeds a prescribed level. CONSTITUTION:The foreign matters, e.g., dust, etc., stick to a disk 10 or a signal detecting part 13A and therefore the part 13A can obtain only the signals lower than a prescribed level out of the disk 10 and is unable to detect an accurate signal. Under such conditions, rubbing pressure control signals 37 are increased so that the rubbing pressure of the part 13A against the disk 10 is increased. Thus the foreign matters stuck to the surface of the disk 10 or the part 13A are quickly removed. Then the part 13A can stably detect the signals of the disk 10. Furthermore, the addition of a tracking control signal 101 is inhibited to a signal detecting means carrier control part 21 so that a signal detecting part transport part 13B can work stably when the signal 37 exceeds a prescribed level, i.e., when the part 13A is unable to accurately detect signals out of the disk 10.
