Title: Metal c ring gasket
Inventor: SHIBATA HIDESHI
IPC: F16J15/08
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To secure sufficient sealing performance even used at a low fastening pressure by forming a metal C ring gasket frequently used for an ultra-high vacuum appliance into an approximately crescent cross section and specifying the ratio of the wall thickness of a part in contact with a mated surface by fastening to the wall thickness of the central part. SOLUTION: The cross section of a metal C ring gasket G1 is formed into a crescent shape gradually and stepwisely thickening the thickness from a B portion and D portion toward a C portion. It is so formed that the ratio of the wall thickness t1 of a part in contact with a counter-part by fastening to the wall thickness t2 of the central part is 1.2 or more. The material of the metal C ring gasket G1 is preferably austenitic stainless steel not to react with gas and the machining method for forming it into C shape is that it is pressed in multi-stages possibly so as not to cause work hardening and normalized under the anoxia atmosphere to the surface hardness less than 300 Hv, thereby providing a superior sealing performance. This constitution can hold the superior sealing performance for a long period.

IPC: G11B11/10
Filed: 1989-05-19
Abstract: PURPOSE:To attain the direct overwrite with a high transfer rate by separating the optical system of an optical head to set an LD at a fixed part and controlling the modulation of the LD with a simple driving circuit. CONSTITUTION:A semiconductor laser LD 3 is fixed to a chassis base 2 and driven by a closed loop control part which contains a temperature control part and defines the quantity of exit light as a controlled variable. A fixed optical system 1 consists of an optical system which shapes the exit beam into the parallel beams, an optical system which detects a magneto-optical signal, a servo signal, etc., out of the laser beam reflected from a magneto- optical disk 11, and an optical system which monitors the quantity of light outgoing from the LD 3. Then a mobile optical system like an objective lens 10, etc., is mounted on an access means which moves from the inner circumference through the outer circumference of the disk 11 and condenses the laser beam radiated from the system 1 onto the recoding film of the disk 11. In such a constitution, the desired and accurate oscillation is facilitated for an erasing pulse and the direct overwrite is attained with a high transfer rate.

IPC: C04B35/64
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To easily produce ceramic sintered bodies of a desired shape without using a carbide tool by cutting a green sheet or block for sintering to a prescribed shape, putting a releasing agent on each cut cross section, carrying out recombination to the original sheet or block shape and pressure sintering and separating the resultant sintered bodies along the each cut cross section.

A releasing agent sheet 4 (hexagonal boron nitride or graphite) is put on each cut cross section of the chips 3 and the chips 3 are recombined to the original sheet shape. Plural green sheets 1, 1', 1'' including releasing agent sheets 4 are piled up while interposing releasing agent sheets 5 to form a green sheet unit 6 and this unit 6 is packed into a hot press and pressure-sintered. Since re-bonding is prevented by the releasing agent sheets 4, 5, the objective ceramic sintered bodies of the desired shape are easily obtd.

Abstract: PURPOSE:To measure the concentration of a specific component in gas by utilizing light with specific wavelength, by fixing a diaphragm which has a window to a coupler projecting from one end part of a piezoelectric vibrator and intermitting light from a projector to a photodetector through the vibration of this diaphragm. CONSTITUTION:An AC voltage (e) is applied to the piezoelectric vibrator 1, which is vibrated. Then the diaphragm 4 which has the window fixed through the coupler 2 is vibrated to intermit the light from the projector 5 to the photodetector 6 by the vibration of the diaphragm 4 and the light is therefore converted into a light pulse train, which is photodetected by the photodetector 6 and converted into an electric pulse train. The vibration frequency, i.e. the number of repetition of pulses can be varied by varying the length and weight of the coupler 2 and the diaphragm 4. Further, a filter is fitted in the window 3 and then the light with specific wavelength is used to measure the concentration of the specific component in the gas.

Abstract: PURPOSE: To provice rust descaling method not generating public nuisance problems in a wide area treatment suited to general uses as well as being applicable to local rust descaling by blowing a fine particle of dry ice to along with high pressure air a surface of a member from which rust must be removed.  
     CONSTITUTION: CO 2  supplied into a freezing machine 2 through a CO 2  sealing valve 1 is cooled by said freezing machine 2 to form dry ice and, thereafter, said dry ice is finely crushed by a crusher 3. Next, a fine particle thereof is combined with high pressure air A in a rotary valve 5 through a hopper like reservoir 4 and, thereafter, blown onto a surface of a member from which rust must be removed from a flexible hose 6 through a nozzle 7. Thereby, rust and a coating on the surface of the member from which rust must be removed are released and removed. Then, after the rust and the coating are removed, the fine particle of dry ice is directly sublimed into the air and, because the surface of the member from which rust must be removed is not wetted, a painting work of the surface from which rust is removed can be immediately carried out.

Title: Convergence correcting device
Inventor: HARADA MITSUNORI
IPC: H04N9/28
Filed: 1992-05-20
Abstract: PURPOSE:To apply a proper misconvergence correcting variable also to a large CRT with wide angle deflection by connecting two diodes which are connected in parallel so as to be mutually reversed at their polarity to both the ends of a vertical auxiliary coil in parallel. CONSTITUTION:Two diodes 31, 32 which are connected in parallel so as to be mutually reversed at their polarity are connected to the vertical auxiliary coil 23 in parallel. When a vertical deflecting current is increased and a current flowing between both the ends of the coil 23 reaches the forward voltage of the diode 31 or 32, the diode 31 or 32 is turned on and a part of the vertical deflecting current is by-passed to the diode 31 or 32, so that the current flowing through the coil 23 is not increased. Since the current of the coil 23 is not increased even when the vertical deflecting current is increased, a misconvergence correcting variable due to the unbalance of a horizontal deflecting current does not exceed a certain value.
