Title: Automatic deburring method for hole inside and device therefor
Inventor: SEGAMI KIYOKATSU
IPC: B23D79/00
Filed: 1991-05-10
Abstract: PURPOSE:To remove burs occurring in such a form as internally crossing at the hole edge of a workpiece by inserting and rotating a deburring cutter such as a reamer and a drill in the hole, and further causing the vibration of a cutter. CONSTITUTION:While a workpiece 12 is being held, a deburring cutter such as a reamer 41 having an outer diameter slightly less than the bore of the workpiece 12 is inserted and rotated in the hole thereof. After the cutter or reamer 41 is inserted, a vibrator 48 is actuated and the reamer 41 is caused to vertically vibrate, or the workpiece 12 is caused to vibrate. The reamer 41 vibrates while rotating, and shape down a bur in the hole. According to this construction, the side of the reamer 41 comes in contact with a bur and scrapes down the bur. Deburring, therefore, can be automatically undertaken without any need of a manual work, and a machining frequency required for deburring can be remarkably reduced.

Title: Mos semiconductor device
Inventor: OOI EIJI
IPC: H01L21/78
Filed: 1977-11-09
Abstract: PURPOSE:To avoid exposure of oxide film due to scribe deviation and enhance the reliability by expanding the scribe region by retreating the oxide film usually extending up to the inactive region back to the vicinity of active region. CONSTITUTION:First and second C-MOSIC elements A, B are adjacently formed on an N type semiconductor substrate 1, and an oxide film 2 is deposited on one element A. At the time, the terminal end of the film 2 is disposed in the vicinity of a pad for electrode bonding 7 which is positioned in the boundary between the active region and the inactive region. That is, by removing the oxide film which is usually extended up to the inactive region, similarly, the element B is also drawn back from the end part of the scribe region 3 and is disposed in the vicinity of the active region. By so arranging, the scribe region 3 is expanded as 3', so that the exposure of the oxide film due to crack and notch at the time of scribing may be prevented. Then, in correspondence with the expanded region 3', N<+> type region 6 is formed by diffusing, in which PSG protective films 4, 5 are deposited while extending them.

IPC: F16C33/60
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To protect the taper roller group of a unit bearing from penetration of water or dust to ensure the performance of the bearing by arranging an annular sealant between both butted end surfaces of a pair of inner races. SOLUTION: An O-ring consisting of an annular sealant 13 is fitted to a pair of annular grooves 12, 12. Accordingly, the annular sealant 13 is arranged between both butted end surfaces 7C, 7C of a pair of inner races. There is the fear that a clearance S2 is formed between the circumferential surface 4A of a bearing shaft part 4 and each inside surface 7A of the inner races 7, 7. In this case, water or dust possibly gets into the clearance S2 from the circumferential part of a unit bearing 6, and then penetrates into the unit bearing 6 from the both butted end surfaces 7C, 7C of the inner races 7, 7. According to this structure, the inter part of the unit bearing 6 is interrupted to the clearance 2 by the annular sealant 13.

Abstract: PURPOSE:To save a space much more as well as to be less costly by providing pressurizing function by means of a spring for the inner surface of a flat plate which is an access for the inspection of the inside of an oil header, in an oiling device which is to secure the amount of oiling in a rotating machine if the power should fail instantly. CONSTITUTION:In a device which supplies oil discharged out of an oiling pump 4, to respective bearings through an oil cooler 3, and an oil strainer 5, an oil header 17 containing the oil strainer 5 is provided with a flat plate furnished with a spring 10 producing proper load, a piston 12, a cylindrical pipe 11 functioning as a cylinder, furthermore, the piston 12 and the like, and a drain pipe 9 is interposed between the flat plate 2 and an oil tank 8. When hydraulic pressure is lowered because the oil pump is instantly suspended if the power should fail instantly, the piston 12 is pushed out because of repulsion by the spring 10, so that oil filled in the oil header is pressed with pressure. By this constitution, hydraulic pressure can thereby be kept to the level to a some extent even though it is short time, so that the amount of oiling to the bearings can thereby be secured.

Filed: 1979-10-17
Abstract: PURPOSE:To obtain the vibrators having different characteristics plus the excellent dampproof property and weather resistance each, by forming the vibrator with the unwoven fabric of the polypropylene fiber and without using the polyester film. CONSTITUTION:The unwoven fabric of the polypropylene fiber is cut to obtain the diaphram component 1 having a sufficient area to produce e.g. a dome-shaped diaphragm. And this component 1 is pressure molded with a pair of upper and lower molding tools 2. In this case, the pressing condition is changed for the diaphragm according to the purpose of applications. For example, in the case of an application for a low-pitched sound, some extent of stiffness is given to the diaphragm while keeping the degree of internal loss the diaphragm 1 has originally. For this purpose, the temperature is increased for the molding tool during the press molding. Thus the characteristics of the diaphragm can be varied with the control given to the pressing and heating conditions during the forming, at the same time securing the excellent dampproof property and weather resistance.

Abstract: PURPOSE:To attain the selection and the use of a cordless telephone system having the call charge less expensive than a radio telephone service network in a radio telephone system that can perform the radio communication with use of the radio telephone service network and also can serve as a cordless telephone system. CONSTITUTION:When a user switches on an operating part 4 in order to secure the function of a cordless telephone set, the radio waves are outputted to a cordless master device from a control part 11 via a cordless radio part 8. Thus the master device transmits repetitively the radio waves including the specific codes used for decision of the radio state. A radio telephone system receives the radio waves through the part 8 and sends them to a code reproducing part 13. The part 13 reproduces the original codes from the received signals and sends them to an error rate detecting pert 14. As these codes are repetitively sent to the part 14, the part 14 can detect the bit error rate by the majority processing based on the contents of the codes detected in plural times. The detected error rate is processed at the part 11 and informed to the user through a display part 10.
