Title: End mill
Inventor: HARADA ISOJI
IPC: B23C5/10
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To reduce work-hardening, frictional heat, chipping, and wear so as to finish a work surface accurately by forming only a first flank on a peripheral edge and increasing the number of edges in an end mill which is provided with spiral peripheral edges on its outer periphery and an end cutting edge at its end surface. SOLUTION: The main body 2 of a solid end mill 1 is a shaft body made of cemented carbide, a spiral peripheral edge 4 is formed at one end of the main body 2 on the top end side, and an end cutting edge 5 is formed continuously with the peripheral edge 4. Also the peripheral edge 4 is provided with a peripheral cutting edge 6 for cutting and formed by forming a flank 8 on a ridge when a chip pocket 7 is formed. Then the peripheral edge 4 forms only the flank 8 so as to increase the number of edges. Thus the amount of work material to be exhausted for each cutting edge is reduced, and work-hardening and heat generation due to assembly deformation of the work material are reduced. In addition, because a cutting resistance is reduced, chipping and wear can be suppressed, and because a cutting distance between cutting edges is reduced, the work surface is finished accurately.

IPC: H01L29/78
Filed: 1991-11-14
Abstract: PURPOSE:To reduce the occupation area of a transistor which requires a wide gate width by arranging source, drain, and gate regions breadthwise in a vertical direction of a substrate and by determining the width according to the thickness of an oxide film formed over the substrate. CONSTITUTION:A gate electrode 1, source-drain regions 2, a channel region 3, and a gate oxide film 41 are arranged equivalently to the cross section of a lateral MOS transistor, and its periphery is surrounded by a field oxide film 4. This layout is a planar substrate structure, where if the dimension of each square unit is 1X1mum<2>, the transistor occupation area is 6mum<2> with lateral 3 unit and vertical 2 unit by square unit occupation. Therefore, the gate length L is used as the dimension on a substrate plane, but because of being elongating in a vertical direction of the substrate, the gate width does not contribute to the plane dimension, the area of a transistor which requires particularly a wide gate width W can be reduced.

IPC: F04B39/02
Filed: 1994-11-09
Abstract: PURPOSE: To improve freezing capacity and a ratio between freezing capacity and a consumption power even when a gap between a rotary shaft and a bearing is decreased by forming a recess-form lubrication oil reservoir in a gap between a rotary shaft inserted in the central part of the rotor of an electric motor part and the bearing part of a frame body pivotally supporting the rotary shaft. CONSTITUTION: Lubricating oil stored at the bottom of a closed container is circulated to an electric motor part contained in the closed container and each lubrication part of a reciprocation compression part 4. In this case, in a bearing 10 mounted on a frame body 2 pivotally supporting the rotary shaft 11 of an electric motor part, a recess-form lubricating oil reservoir 21 is formed in the bearing 10 side in a gap between the rotary shaft 11 and the bearing. After lubricating oil sucked through a lubricating oil passage 20 formed in the rotary shaft 11 is stored in the recess-form lubrication oil reservoir 21 once, the lubricating oil is led out to respective lubrication parts for circulation. This constitution forms an excellent oil film even when an HFC refrigerant and ester lubricating oil are used and improves freezing capacity.

Title: Method and device for encoding/decoding moving image signal
Inventor: MACHIDA YUTAKA
IPC: H04N19/196
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for encoding/decoding digital moving image signal by which the establishment of synchronism by a false synchronizing word or out-of-synchronism caused by bit error in a synchronizing word can be suppressed even when the bit error is caused in a bit stream encoding a moving image signal. SOLUTION: The number of bits in a variable length code string for one picture is counted by a bit count means 103, and the error correction encoding of this length information into a block code is performed by an error correction encoding means 104. A frame constituting means 105 adds the block code to the head of the variable length code string for one picture, and a synchronizing word adding means 106 adds the synchronizing word before it. On the decoding side, the error correction decoding of the block code is performed and when there is any error, the establishment of synchronism due to the false synchronizing word is suppressed. When there is no error, in the case of identifying the synchronizing word, it is estimated as the synchronizing word although it is a little different from a synchronizing word bit pattern, and out-of-synchronism caused by bit error is suppressed.

IPC: G09F9/33
Filed: 1994-12-02
Abstract: PURPOSE: To provide a synchronizing circuit with a simple configuration in a display device in which picture is reproduced through the use of LEDs by synchronizing the picture data output from an LED printer head with the sensor signals executing the picture data output timing and provided on a reflection mirror and outputting the picture data. CONSTITUTION: The driving circuit of a reflection mirror 305 is allowed only to a constant motion independently of other circuits to eliminate the need of a timing control circuit. A photometric sensor 307 monitors the condition of the mirror 305 during its constant motion. When the sensor 307 discriminates that the mirror 305 passes through a prescribed position, the sensor 307 sends a pulse to the output processing section of picture data. The output processing section where the pulse is received transmits again the leading data of the picture data to be reproduced. Thus, the picture data outputted from an LED printer head is synchronized by the signals from the sensor 307 of the mirror 305.
