Title: Ohmic, electrode, semiconductor device and manufacturing method thereof
Inventor: YAKURA MOTOTSUGU
IPC: H01L29/205
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To stabilize the contact resistance low against a high temp. heat treatment of an Ohmic electrode, by providing a Pt or Pd layer on an n-type InGaAs layer and providing at least one metal layer thereon. SOLUTION: A Pt layer 13a is formed between an n-type Inx Ga1-x As layer 12 and metal layer 14 on a compd. semiconductor layer 11 such as GaAs layer, thereby preventing the constituent metal of the metal layer 14 from diffusing into the n-type Inx Ga1-x As layer 12 and vice versa, due to the heat applied during the manufacturing process. Thus, the contact resistance is kept low i.e., Ohmic contact is held even at elevated heat treating temps. after forming of the metal layer. This is the same if the Pt layer 13a is replaced with a Pd layer 13b. The metal of the metal layer may be Ti, Pd, Au, Mo, Ta, W, etc.

Title: Synchronous tapping device of numerically controlled machine tool
Inventor: KITAGAWA KATSUYOSHI
IPC: B23G1/16
Filed: 1989-12-07
Abstract: PURPOSE:To safely carry out tapping by comparing an overload monitoring torque level preset with a torque command value during processing when overload is caused by friction of a tapper and/or improper processing conditions etc., so as to detect the overloaded condition. CONSTITUTION:A main spindle motor torque command TQ is input from a main spindle controller A to the overload detecting portion 12 of a main spindle motor 8 and then the overload detecting portion 12 compares the command TQ with a overload monitoring torque level so as to carry out monitoring of overload. When overload is detected the overload detecting portion 12 outputs an overload signal OL and a position command portion 1 stops issuing position commands to the main spindle controller A and a z-shaft controller B in response to the signal OL. In this case, a time constant computing portion 13 sets a computed time constant at acceleration and deceleration processing portions 2a, 2b and uses the time constant to stop the main spindle motor 8 and A z-shaft motor 10 while maintaining their syncronicity. Tapping is thus carried out safely without damaging working jigs or machines.

Title: Tape cassette
Inventor: ISHIKAWA KO
IPC: G11B23/04
Filed: 1992-11-30
Abstract: PURPOSE:To provide the tape cassette having excellent vibration attenuation characteristic and high antistatic effect. CONSTITUTION:The part (support area) of a cassette housing 1 in contact with a tape driving device is formed as a carbon fiber packed part 6 (carbon fibers are packed at 20wt.% into an ABS resin). As a result, rigidity is enhanced by packing of the carbon fibers and, therefore, the vibrations transmitted from the outside are effectively attenuated and there is no adverse influence on a tape. Electric resistance is lowered by packing the carbon fibers and, therefore, electrification is hardly generated. Even if triboelectrification is generated at the time of using in low humidity environment, the electrified charges are rapidly escaped to the tape driving device side and, therefore, the pickup of the dust by the electrification and discharge noise, etc., are effectively prevented.
