Inventor: SHIRASAKI TAKAYUKI
IPC: H02N2/16
Filed: 1989-01-25
Abstract: PURPOSE:To obtain a large output oscillatory wave motor having good performance by securing a sliding member composed of composite resin, where filler is mixed with thermoplastic resin having transition point to glass higher than 100 deg.C, to a supporting member composed of elastic material having good thermal conductivity. CONSTITUTION:When frequency voltages having phases different by 90 deg. each other are applied onto electrodes 1a, 1b polarized alternately in the direction of thickness, vibration wave is produced in the circumferential direction on the sliding face of a vibration member 2, and a moving member 3 is rotary driven through frictional force on the sliding faces of the vibration member 2 and a sliding member 3b. When the vibration member 2 is composed of elastic material having low coefficient of thermal expansion and the counterpart sliding member is composed of reinforced composite resin, the sliding face is subjected to hardening processing. The sliding member 3b is composed of thermosetting resin or composite resin thereof having transition point to glass higher than 100 deg.C.

IPC: C03B20/00
Filed: 1986-01-29
Abstract: PURPOSE:To stably produce the titled preform for optical fiber having a high numerical aperture by forming a layer of quartz glass added with fluorine on the outer periphery of a pure quartz glass layer which is provided on the outer periphery of a rod to form the outermost periphery of a core rod. CONSTITUTION:A starting rod consists of quartz glass contg. GeO2 necessary to control the specific refractive index difference from pure quartz glass to >=1.5%, and is used as the core rod 1. A thin pure quartz glass layer having a thickness 1/60-1/125 times the outer diameter of the starting rod is provided on the outer periphery of the starting rod. The layer of quartz glass added with fluorine is further furnished on the outer periphery. The clad pipe 2 is formed with quartz glass whose refractive index difference is controlled to <=-0.3% by the addition of fluorine. Since the fluorine-added layer is provided on the outer periphery of the core rod 1, the vitrification temp. of quartz glass is decreased, the deformation of the core glass is controlled to the minimum in spite of direct vitrification for many hours, the thickness of the coated pure quartz glass layer can be sufficiently kept even in the succeeding high-temp. process such as drawing, and the degree of freedom in the processing can be expanded.

Title: Defective data memory
Inventor: MIYAZAKI NAOKI
IPC: G11C29/44
Filed: 1990-01-25
Abstract: PURPOSE:To enable analysis in a short time to determine whether an optional tester pin is defective or not by allowing a defective data for each pin of an IC to be tested to be stored in real time through an input terminal. CONSTITUTION:An acceptable or defective data to be judged during a test is supplied in real time to a defective data memory 1 from input terminals 11-13. An address buffer 2 sets an address through a data bus 10 to read out a defective data. Then, defective data of all pins read out with the device 1 are applied to one-hand inputs of AND gates 4A-4C. A register block 3 is built in the number corresponding to that of pins of an IC tester. Outputs 17-19 of the register block 3 are applied to the other inputs of the gates 4A-4C. All of the outputs of the gates 4A-4C enter an OR gate 5, an output of which gives '1' only when a specified pin or all the pins are defective. An output terminal 5A leads to a data bus 10 and by checking an address when the '1' is given, it can be learned what ordinal number of patterns is defective.

Title: Cam shaft bearing structure for internal-combustion engine
Inventor: MUKAI MASATO
IPC: F16C17/02
Filed: 1982-02-03
Abstract: PURPOSE:To ensure the axial flatness of the bearing face when fastening a cylinder head to a cylinder block, by inclining the opposite side to the cylinder block fastening side of a lower cam holder of a cam shaft to the cylinder head side. CONSTITUTION:Since it is fastened to a cylinder block through bolts 15, 151 provided in front and rear of the inside A near to space S of a lower cam holder 16, the inside A is pressed downward while the outside B will deform upward because it is not fastened directly to the cylinder block through bolts. Said upward deformation is absorbed because the downwardly inclined face c is formed at the outside of the lower cam holder 16, thereby the outside B will be a flat face where the inside A and the bottom are continuous in the axial direction.
