Title: Chamferring machine
Inventor: OMURA TAKUJI
IPC: B24B21/00
Filed: 1987-03-25
Abstract: PURPOSE:To enable smooth chamferring work efficiently by travelling a lapping tape with tension being applied thereon, then pushing one end of a work against a groove through the lapping tape under the condition where the work can move freely in single plane. CONSTITUTION:A motor 15 rotates a roll 14 so as to travel a lapping tape 12 in the direction of an arrow, and a powder brake 16 functions to apply predetermined tension onto the lapping tape 12. When pressure is applied by an air-cylinder 19 through a pressurizing jig 18 such that a plate glass 11 is pushed against the groove section in a base 17 through the travelling lapping tape 12, edge of the plate glass 11 is machined. Here, two edges of A and B are machined by the lapping tape having the width same with that of the plate glass 11, while two edges at C are machined through deformation of the lapping tape at wider portion than the width of the plate glass 11.

Title: Optical recording medium
Inventor: YOSHIBE SATOMI
IPC: G11B7/24076
Filed: 1995-03-29
Abstract: PURPOSE: To produce an optical disk which is small in the variation of a crosstalk quantity between the inner peripheral part and outer peripheral part and is low in the level by using a substrate which is changed in the depths of guide grooves according to variations in the film thickness and characteristics of a recording layer. CONSTITUTION: The substrate of a diameter of 305m formed with the guide grooves at a pitch of 1.6μm is prepd. The depths of the guide grooves are 75nm in the inner peripheral part, 80nm in the middle peripheral part and 85nm in the outer peripheral part. The widths of the lands and grooves are both 0.8μm and the magneto-optical disk is produced by forming the film of a magnetic recording layer by sputtering on this substrate. While this magneto-optical disk is kept rotated at l000rpm, marks of a length of about 2μm are recorded on the lands of the inner peripheral part, the middle peripheral part and the outer peripheral part and thereafter, the respective adjacent grooves are reproduced with the reproducing beam intensity of 1.5mW and the crosstalk quantity is measured.  As a result, the crosstalk quantity of the substrate formed by this process is verified to be smaller than by the conventional method and to be small in the variation.

Title: Fm demodulating system
Inventor: KIMURA KENJI
IPC: H04N5/923
Filed: 1981-05-14
Abstract: PURPOSE: To elevate the quality of a reproducing picture, by preventing lack of a carrier wave of a reproducing FM modulated wave in case when it has been recorded with a high FM modulation degree.  
     CONSTITUTION: Only a fundamental wave of a reproduced FM modulated wave  is detected and is converted to a square wave by the first limiting circuit. By  this square wave, a pulse whose constant pulse width is less than the highest frequency period of the reproduced FM modulated wave is generated. An FM  modulated wave obtained by superposing this pulse on the FM modulated wave  is converted to a square wave by the second limiting circuit, and after that, is  FM-demodulated, and a video signal is obtained. That is to say, the FM modulated wave reproduced by a magnetic head 5 is led to an equalizing circuit 7  through a recording and reproducing changeover switch 5 switched to the reproducing side, compensates its frequency characteristic, and after that, removes a  lower side band wave component by a high-pass filter 13, and fetches only an  FM carrier wave component.

IPC: G01B5/18
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To easily create a lock state in which a pin needle is prohibited to project and an unlock state in which the pin needle can be used by providing a projection body in the outer periphery of a bushing guide and forming a slide groove which make the projection body to appear and disappear. SOLUTION: When a turntable bushing guide body 8, while in use, is turned to match the projection body 8b formed in the outer periphery to the slide groove 10 formed in a cap 2, the bushing guide 8 can appear from the cap 2 without making the projection body 8b abut on a tip face 2d. When the bushing guide body 8, while not in use, is turned from a state, in which the bushing body 8 is used, the projection body 8b provided in the outer periphery of the bushing guide 8 leaves from the slide groove 10, becoming being capable of abutting on the tip face 2d of the cap 2. Accordingly, even the bushing guide body 8 is pressed, the bushing guide 8 becomes lock state, making the appearance of the projection body 8b impossible.

     CONSTITUTION: The treatment method for the gas based on fluorine which contains the hydrofluoric acid and can contain the uranium or other condensable gases is executed in the following manner: The gas described above is forcibly cooled in order to condense HF to a liquid form and the other condensable compds., by which the condensed liquid hydrofluoric acid contg. the gaseous fluorine, the noncondensable gases to be discarded and/or other condensed compds. in a dissolved and/or suspended state is obtd. The resulted suspension is then filtered to separate the solid condensate from the soln. based on the anhydrous liquid HF. The force cooling described above is executed at a cooling temp. of -78°C, more preferably -80°C. If the temp. is too low, there is a danger of clogging the device by condensing of the solid HF. If the temp. is too high, the insufficiency in the condensation yield of the HF is resulted.

Abstract: PURPOSE:To prevent occurrence of failures due to the storage of dust as well as to prevent the occurrence of unsanitary problems due to exhaust air by providing a main body with a storage section for storing dust arrested by a dust arresting section, outside of an air duct. CONSTITUTION:Dust 42 forwarded to a main body 2 is arrested into a dust collecting section 22 via an air duct 21 including a suction port 23. Exhaust air after dust has been collected, passes through a chamber where an electric blower 21 is arranged, while the minute components of dust being arrested by a filter 20, so that purified air after filtration is thereby exhausted out of an outlet port 25. After cleaning is over in a general way, let the main body 2 stand upright, a cleaning-over button, for example, is then depressed. The control section starts operating with the cleaning-over button depressed, a motor is rotated, and a movable wall 41 slides then. This thereby permits a partition between the dust collecting section 22 and a storage section 40 to be fully opened, so that heavy dust 42 stored at the bottom of the dust collecting section 22 falls down in the storage section 40.

Abstract: PURPOSE:To reduce the number of gear trains as compared with change gear stages by providing a sub-transmission in between a second lay-shaft and plural gear trains and selectively engaging said second lay-shaft with a gear train in series. CONSTITUTION:Power from an engine is transmitted to the driving wheels of an automobile via an input shaft 1, a second clutch 1B, a second lay-shaft 4, a sub-transmission, one gear train corresponding to the first gear, and an output shaft 2, to accelerate the automobile. Since the change gear ratio of the sub-transmission is such a gear ratio as to accelerate a speed between the second lay-shaft 4 and one gear train, the engagement of the sub- transmission with said gear train of the first gear results in a condition of the second speed. Accordingly, the power from the engine is transmitted to the driving wheels of the automobile via the input shaft 1, a first clutch 1A, a first lay-shaft 3, one gear train corresponding to the third gear, and the output shaft 2, thereby, enabling the number of gear trains to be reduced compared with change gear ratio.
