The obtd. normal pressure type boron nitride is heated in a nonoxidizing atmosphere and high purification treatment is performed. Then, it is directly converted into a cubic boron nitride at 6 to 7 Pa at 1,550 to 2,00 deg.C in the absence of a catalyst and sintered to obtain a cubic boron nitride sintered body. The obtd. sintered body contains >=99.5 vol.% the cubic boron nitride in which the cubic boron nitride particles are bonded to each other without containing a binder and the body shows no decrease in the strength in 800 to 1,400 deg.C temp. range contains 0.01 to 0.5 vol.% compressed type hexagonal boron nitride and has <=1 μm particle size.  Thereby, a cubic boron nitride sintered body having a dense structure and high strength with fine particles can be obtd.

Title: Belt transmission having automatic tension regulating mechanism
Inventor: KAWAHARA HIDEAKI
IPC: F16H7/16
Filed: 1989-03-15
Abstract: PURPOSE:To prevent the occurrence of damage to a toothed belt, etc. and make the captioned transmission light weight and compact by dividing a driving pulley into a sprocket on a shaft side and an eccentric wheel on the outside thereof and power transmittably linking both with a chain. CONSTITUTION:As a crank shaft 1 starts rotating, a crank sprocket 6 which is one with same is also rotated to wind up a chain 15. However, an eccentric wheel 10 is not rotated but pulled by the chain 15, approaching the axis O1 direction of the sprocket 6 to reduce the eccentric quantity thereof and giving tensile force to a toothed belt B. Finally, the eccentric movement of the eccentric wheel 10 is restrained by the belt B and stopped. Due to this restraint, the eccentric wheel 10 is rotated on its own axis O2 in that position and, due to this rotation, the belt B travels to transmit power to a driven pulley 16. Since the number of waves of the sprocket portion 9 of the crank sprocket 6 and the sprocket portion of the eccentric shaft 10 is equal, the speed ratio between the crank shaft 1 and the eccentric wheel 10 is 1:1, without reducing the rotating speed.

Title: Heating cooker
Inventor: UEHASHI HIROYUKI
IPC: F24C7/02
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To enable quick initialization for an infrared sensor by a method wherein an infrared detection part is provided with a chopper to cyclically interrupt infrared rays radiated from a food and when the closing of a power source and the opening of a door are detected, a chopper motor is driven or controlled for a specified time length. SOLUTION: In the operation of a microwave oven 100, when a power source is closed, it is judged whether a door is opened or not based on the results of detection with a door opening sensor 509 and when the opening of the door is detected, a chopper motor 9 is driven to rotate a chopper for a specified time length (for example, 2 min.). If an infrared sensor 1 is in an initialization mode, an operator is prompted to execute an initialization. In this manner, when the power source is closed before the start of the initialization work for the infrared sensor 1 at a factory or the like while the door is opened, the chopper motor 9 is automatically driven to rotate the chopper. This enables quickly stabilizing of the detection of temperature with the infrared sensor 1 during the initialization work thereby curtailing time loss at the initialization.

Title: Method for grinding edge of circular thin plate
Inventor: NISHI KENICHIRO
IPC: B24B9/00
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for grinding an edge of a circular thin plate capable of shortening the grinding time. SOLUTION: By combining the vertical movement in the Z-direction of a wafer 25 and the movement in the Y-direction of a grinding wheel 72 for rough grinding, the grinding wheels are arranged at prescribed places (H1 to H5, five places) in the vicinity of the outer peripheral edge part of the wafer 25. By giving rotation and relative movement to the grinding wheels 72 and the wafers 25 from this state, the outer peripheral edge parts of the wafer 25 are roughly ground to a convex surface. At the completion of the rough grinding, a grinding wheel 73 for finishing grinding and the wafer 25 are rotated respectively, while the grinding wheel for finishing grinding is put in reciprocating movement in the radial direction and along the outer peripheral edge part of the wafer 25. By moving the wafer 25 up and down, the outer peripheral edge part of the wafer 25 is ground to finish smooth.

Title: Digital video recording and reproducing method for high- quality television signal
Inventor: YOKOYAMA KATSUYA
IPC: H04N5/91
Filed: 1984-04-03
Abstract: PURPOSE:To attain the video record and reproduction with a standard digital video recording/reproducing device by converting high-quality TV signals equivalent to two lines into signals equivalent to one line of said recording/producing device for video record and reproduction and at the same time deleting the signals equivalent to prescribed plural lines at the upper and lower ends of a picture to perform the video record and reproduction. CONSTITUTION:For high-quality TV signals, 720 samples out of 936 samples equivalent to two lines including 94 samples of color signals and 374 samples of luminance signals are converted into video signals contained in the picture signals for cideo record and reproduction. Therefore the high-quality TV signals are compressed properly in accordance with the record capacity of a standard VTR for video record and reproduction. The video signals equivalent to 8 lines at upper and lower end parts of the picture plane of an odd field are disused together with those equivalent to 7 lines at upper and lower end parts of the picture plane of an even field. Thus the upper and lower end parts of a picture plane are reduced just by 1.54% and 1.34% at odd and even fields respectively. Such small reduction of the picture plane produces practically no problem at all.

Title: Device for containment of plate member
Inventor: KUBONAI KOUICHI
IPC: H01L21/50
Filed: 1982-04-21
Abstract: PURPOSE:To enable to perform containment smoothly by stopping and containing securely at a fixed position even in case of inclination by a method wherein the inside of a containment jig is so constituted that a holder movable up and down is enabled to move up and down at every time of the containment of a plate member, and a detector is constituted so as to output the signal which stops the movement of the holder. CONSTITUTION:When a lead frame mounted on the holder 11 turns in the state of inclination for some reason, the posture of the lead frame 12 is corrected to an approximately horizontal state by moving the holder 11 down sufficiently to a lower position. When the holder 11 moves up again after such a correction, and the up movement of the holder 11 is stopped at the point of shutting off the detector 20, the lead frame is mounted normally, and the lead frame can be contained just in the same manner as the case of being moved down. Therefore, even when the lead frame turns in the state of inclination at the time of the containment of the lead frame, the former lead frame can be set up at a normal position at the time of the containment of the next lead frame, and thereby the fixed number of lead frames can be contained smoothly and accurately.

Abstract: PURPOSE:To reduce the occurrence of flickering in the part of stroke display as compared with the part of interlace display and to prevent eyestrain even in the case of viewing the display for a long time by performing not the ordinary interlace display of a vector in a graphic display area, but the stroke display of it. CONSTITUTION:At a counter which is disposed in a read-out display means 52, an address is counted up and fetched so that it may go ahead on the line of the vector based on the start-address, the end-address and the sweeping width of the vector. Thus, horizontal and vertical signals for sweeping on the line of the vector are outputted, meanwhile, a brightness signal is kept at H level, and the stroke display of the vector is performed by the horizontal and vertical signals. Thus, the number of screens capable of displaying for one second in the case of the stroke display is increased more than that in the case of the interlace display, so that the occurrence of flickering can be prevented, and the eyestain can be prevented even in the case of viewing the display for a long time.
