Patent JP-H0255598-A (JP)
Title: Variable speed induction motor
Inventor: SATAKE TOSHIHIKO
IPC: H02P25/024
Filed: 1988-08-18
Abstract: PURPOSE:To protect rotation of a stator against trouble due to heating by rotating the rotary stator through sliding on the sliding face or the bearing face or through rolling balls. CONSTITUTION:A bearing 50 having a bearing face 57 is secured to the outer circumference of a rotary stator 12A. A bearing 51 has a centrifugal bearing face 58 arranged on the inner circumferential face of a machine frame facing with the rotary stator 12A. A ball bearing is placed between the centripetal bearing face 57 of the bearing 50 and the centrifugal bearing face 58 of the bearing 51. Consequently, the rotary stator 12A rotates concentrically with a rotor. Even if the face bearing expands due to heating or abnormal temperature rise, the gap between the faces 57, 58 enlarges and influence of expansion onto the face bearing can be neglected.

Title: Power system for lsi
Inventor: HORI CHIKAHIRO
IPC: H01L29/78
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a power system for an LSI which can easily supply a voltage lower than the power supply voltage of an LSI from the outside to the LSI without requiring an exclusively used circuit for converting and stabilizing the voltage and can easily propagate signals between a high potential side logic circuit and a low potential side logic circuit in a charge re-utilizing type circuit. SOLUTION: When the input and output of a logic circuit are stable, an electric current flows between a first power supply line 1 and a second power supply line 3 through at least one logic circuit constituted of high and low potential side functional circuits 5a and 5B to which voltages are supplied from the first and second power supply lines 1 and 3 and, at the same time, the voltage fluctuation of the lines 1 and 3 is corrected by changing the equivalent resistance value of the logic circuit in accordance with the voltage fluctuation of the lines 1 and 3.

Patent JP-S6184265-A (JP)
Title: Transfer mechanism for thermal transfer printer
Inventor: OGITA HIROMITSU
IPC: B41J2/325
Filed: 1984-10-01
Abstract: PURPOSE:To maintain a constantly fixed releasing and achieve normal transfer of an ink, by fitting a guide plate or a guide rod between a platen and the first guide roller. CONSTITUTION:The guide plate 8 or the guide rod 9 is fitted between the platen 2 and the first guide roller 3. Accordingly, since a laminate of a transfer paper and a transfer ribbon is guided at a constantly fixed angle in the range from the platen 2 to the first guide roller 3, the releasing angle is constantly fixed, and troubles such as nonuniformity of color and generation of void in transferred images can be prevented from occurring, so that normal transfer of the ink can be achieved.

Title: Click dome sheet
Inventor: YOSHIOKA TOSHIAKI
IPC: H01H13/48
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To impart a desired click feel even if there is no spacer by forming the recessed parts around the pressing part of a click dome sheet having one or more pressing parts protruding in dome shape. SOLUTION: In a click dome sheet 1, the pressing part 12, the recessed part 13 and the disconnecting part 14 are formed by heat press molding on a sheet composed of a synthetic resin such as polyethylene terephthalate(PET). The recessed part 13 is formed so as to project to the switch board 2 side on the opposite side in the protruding direction of the pressing 12. The recessed part 13 does not surround the whole periphery to a single pressing part 12, but is disconnected in at least one place. This disconnecting part 14 corresponds to air vent clearance when pushing the pressing part 12. Thus, since there is no need to use a separate spacer, the material cost, the manufacturing mold cost and the assembling cost of a spacer can be reduced.

Filed: 1986-09-02
Abstract: PURPOSE:To make it unnecessary to use a gas strong in toxicity and to facilitate film quality control, by forming a graphite target in which a specific amount of aluminium is buried. CONSTITUTION:A composite graphite target 4, in which aluminium nitride (AlN) is buried, and a substrate 10, on which a carbon thin film is to be formed, are installed in a vacuum chamber 1 and then pressure in the vacuum chamber 1 is reduced and a H2 gas is introduced. After chamber pressure is stabilized, high-frequency power is set and a sputtering process is performed. Resultantly, a semiconductive carbon thin film is formed. A suitable area ratio of AlN buried in a graphite target is 0.1-10%. The AlN amount of 0.1% or less does not cause a change in resistivity, and that of 10% or more is not suitable for formation of a wide gap semiconductor. Suitable chamber pressure is 1.33Pa-665Pa. A similar effect can be also obtained by the use of a sputter mixed gas consisting of H2 and inert gases such as Ar and He.

Inventor: AOKI IWANE
IPC: B29B17/04
Filed: 1990-08-02
Abstract: PURPOSE:To prevent a vol.-decreasing and solidifying apparatus from overloading by a method wherein electric current in a plastic vol.-decreasing and solidifying apparatus is detected and a variably cutting conveyer feeding plastic waste to the vol.- decreasing and solidifying apparatus is controlled according to the value. CONSTITUTION:Plastic waste fed in a vol.-decreasing and solidifying apparatus 39 is compressed by means of a screw in a casing 41 and is softened based on natural heat generation or heating and is changed in a solid product with a proper zone, which is fed in a hopper 32 from an outlet 42 and is loaded on a truck 40. In this instance, if electric current in a driving motor 67 for the vol.-decreasing and solidifying apparatus 39 is within a rating value, motors 47, 62 and 67 are continuously driven and as a switching damper 26 opens an outlet 30 and a control panel 53 is elevated, the plastic waste is sent out without restriction. However, if the vol.-decreasing and solidifying apparatus 39 becomes overloading due to a certain reason, the electric current energized in the motor 67 becomes too large and if the value exceeds a preset upper limit by means of a detecting device 65, the motor 47 is stopped by outputting a signal. The screw 45 is stopped thereby and feeding of the plastic waste is stopped.
