Title: Cylinder lubrication evaluator for piston engine
Inventor: TAKAISHI TATSUO
IPC: G01M15/04
Filed: 1986-12-25
Abstract: PURPOSE:To enable evaluation of sliding condition between a cylinder liner and a piston cylinder during actual operation, by building up a part of the cylinder liner serving as a desired ultrasonic wave path out of a material with a better ultrasonic transmissivity. CONSTITUTION:A material 31 with a better untrasonic transmissivity such as steel is inserted securely into a cylinderliner 3 made of cast iron to be molded and wrought as one-piece cylinder liner. Then, ultrasonic wave transmitting and receiving elements 71 and 81 are mounted on the portion of the material 31, an ultrasonic wave is beamed through the inner surface of the cylinder toward a sliding surface from the transmitting element 71 and the ultrasonic wave reflected from the sliding surface is received with the receiving element 81. Unlike the cylinder made of the cast ion only, the better ultrasonic transmissivity thereof achieves a higher ultrasonic detection accuracy, thereby facilitating the evaluation of lubricating condition of the sliding surface. It also should be noted that tapering in the shape of the material as illustrated can reduce effect of delayed echoes reflected back from the circumferential surface thereof, thereby allowing further improvement in the accuracy.

Title: Insulated gate field effect transistor
Inventor: TERAJIMA TAKAMI
IPC: H01L29/06
Filed: 1988-12-06
Abstract: PURPOSE:To heighten the endurable voltage and besides lessen the ON-resistance comparatively by making the plane shape of cell regions almost a square or an almost a hexagon, and arranging them like islands so that their corner sections may face each other. CONSTITUTION:The plane shape of cell regions 9 is almost a square or almost a hexagon, and the cell regions 9 are arranged like islands so that the corner sections of the cell regions 9 may face each other. Accordingly, when reverse voltage is applied to a pn-junction constituted with a cell region 9 and a drain region 1, the drain region 1 between the corner sections of the cell region 9 and those of other cell regions 9 neighboring with the cell region 9 is filled with a depletion layer effective for easing electric field concentration prior to other parts of the drain region 1. This increases the breakdown voltage at the corner sections of the cell region 9 where the electric field concentration is easy to happen. Consequently, the breakdown voltage of the field effect transistor rises. In addition, as the drain region 1 adjoining the peripheral part of the cell region 9 has a comparatively large area, this works effectively as a drain current path and the increase of the ON-resistance can be prevented.

Filed: 1989-11-28
Abstract: PURPOSE:To prevent sprious malfunction by providing a circuit to sufficiently attenuate the 1/2 component of a video intermediate frequency without attenuating a frequency near the video intermediate frequency between a tuner and a preamplifier. CONSTITUTION:Between a tuner 2 and an SAW(surface acoustic wave) filter preamplifier 4, a circuit 10 is provided to sufficiently attenuate the 1/2 IF component.

IPC: H02N2/00
Filed: 1988-12-06
Abstract: PURPOSE:To reduce the outside diameter of an ultrasonic motor by obliquely projecting a plurality of supporters at a regular interval in the direction of motion of a moving body to a support member and holding the moving body or a stator by the supporters. CONSTITUTION:The supporters 3a of a stator support member 3 are projected obliquely at a certain inclination in the direction of motion of a rotor 2. Supporters 20a are projected integrally at a certain inclination in the direction of motion of the rotor to a rotor base material 2a. When the AC voltage of specified frequency is applied to the piezoelectric body 1b of a stator 1, the piezoelectric body 1b is excited, and progressive waves are generated in the driving surface 1c of an elastic body 1a. Since the rotor 2 is pressured and brought into contact with the driving surface 1c by a pressure member 6, it is friction-driven by progressive waves generated in the elastic body 1a and turned. Accordingly, the stator support member 3 and the outside diameter of a rotor support member 20 can be made smaller than conventional devices only by the inclination sections of each supporter 3a, 20a of the members 3 and 20.
