Title: Digital signal recording system
Inventor: KATOU MISAO
IPC: G11B20/18
Filed: 1980-06-11
Abstract: PURPOSE:To correct efficiently errors in both width and longitudinal directions of a track, by changing data words to a group in accordance with weighting of each bit, when forming a parity in the width and longitudinal directions of the track. CONSTITUTION:Digital words S1, S2... are distributed in order by each word to i-th, i+d-th, i+2d-th recording tracks, and a P parity word is formed by 3 words which are continued as time series. These digital word groups from a frame by adding a Q parity word together with a synchronizing code and an error detecting code. Also, data words of each frame constitute a group in accordance with weighting of each bit of data, respectively. And, a P parity is constituted by combining the groups of data words which have been time-delayed in the longitudinal direction of a track, varying track in order, which is made a parity word in the frame. Also, a Q parity is formed by combining the groups of data words and parity words, and is distributed and recorded to residual tracks.

Title: Tweezers
Inventor: MIKI KATSUHIKO
IPC: B24B9/02
Filed: 1989-03-29
Abstract: PURPOSE:To prevent lifetime from being shortened after heat treatment and to prevent a microshallow pit from being produced by light etching operation by a method wherein the surface as a picking-up part of tweezers is constituted of titanium. CONSTITUTION:Tweezers 11 are formed of titanium; their base part 11a is bent and formed to be V-shaped; on the other hand, picking-up parts 11b at their tip are bent and formed to be L-shaped with reference to the base part 11a, the picking-up parts 11b are constituted in such a way that they are situated in a position which is lowered by one step from the base part 11a. Thereby, a drop in lifetime of a semiconductor wafer after heat treatment is small as compared with a case where the wafer is treated with ordinary tweezers; a microshallow pit produced when the surface of the semiconductor water after the heat treatment is light-etched becomes small.

Title: Driving circuit for brushless motor
Inventor: ABE HIDEAKI
IPC: H02P6/24
Filed: 1991-04-15
Abstract: PURPOSE:To abruptly stop rotation of a brushless motor when supply of a power source is stopped. CONSTITUTION:A power supply stop sensor 22 for sensing the fact that supply of power source is stopped according to OFF of a main switch SW1, is provided. A controller 20 turns ON all transistors Q1-Q3 according to the output of the sensor 22, and turns OFF all transistors Q4-Q6. Thus, when a rotor 2 is rotated by an inertial force, it is braked by using a counterelectromotive force induced in a coil 9. The sensor 22 senses stop of the supply of power source from a step-down output. Thus, even if the power supply is stopped, it is braked in a state that the other circuit of a driving circuit is active due to a delay in the voltage drop of the driving power source.

Title: Scroll type compressor
Inventor: MATOBA YOSHIAKI
IPC: F04C27/00
Filed: 1984-04-20
Abstract: PURPOSE:To aim at stabilizing the supporting force of a revolving scroll, by making a high pressure from a large volume closed casing act upon a high pressure chamber to reduce pressure pulsation affecting the high pressure chamber. CONSTITUTION:The volume of the space in a closed casing 1 is relatively so large that the pressure in the casing 1 does not pulsate, substantially, irrespective of pulsation of compressed fluid discharged from a compressing element 4. Accordingly, the pressure in a high pressure chamber 14 communicated with the casing 1 through a passage 13 also stabilizes, and therefore, pressure pulsation becomes less. As a result, a high pressure having less pulsation acts upon the pressure receiving area 15 of a revolving scroll 3 in a high pressure chamber 14. The thrust force by this pressure may offer a stable supporting force for urging the revolving scroll 2 against a stationary scroll 2. With this arrangement the lowering of power due to the leakage of coolant between the thrust faces of both stationary and revolving scrolls 2, 3 and power loss due to an excessive slide resistance may be prevented.

Abstract: PURPOSE:To prevent the formation of a crown during the implementation of epitaxial growth by making the diameter of a bond wafer shorter than that of a base wafer, selecting a smaller bevel width for the bottom surface of a bond wafer, or adding bevels so that the sizes of the base wafer junction surface and the bond wafer junction surface are the same. CONSTITUTION:An SOI structure substrate is a junction wafer which consists of a base wafer 21a, a bond wafer 21b with a smaller diameter, and an oxide film 21 which joins these wafers and in which the bond wafer 21b is a thin film. Since the bevel width w5 and the bevel angle theta5 of the upper surface of the base wafer 21a disappear in practical terms because the bond wafer 21b is a thin film, values must be set to prevent the formation of a crown during the formation of an epitaxial layer. When the bevel width of a beveled area 32b on the bottom surface of the bond wafer 21b is W8 and the depth of the bevel is d8, W8 is kept to 50mum or less.
