Title: Less resonating optical disk
Inventor: KAMAKURA IKUTO
IPC: G11B7/24015
Filed: 1989-09-13
Abstract: PURPOSE:To suppress oscillation amplitude by specifying the outside diameter of an inner peripheral side spacer to >=45mm, the adhesive region between an optical disk substrate and the inner peripheral side spacer to >=45mm and below the outside diameter of the spacer and the length of an unadhered parts for air venting to <=10mm. CONSTITUTION:The outside diameter X of the inner peripheral side spacer 1 is specified to >=45mm and two sheets of the upper and lower optical disk substrates 2 are stuck to each other via the spacer 1 and the outer peripheral side spacer 3. The assurance of the adhesive region of the substrate 2 and the spacer 1 at >=45mm and the size approximately equal to the outside diameter X is more preferable for production. The length Y in the unadhered parts 4 for air venting is acceptably <=10mm and is generally more preferably about 3 to 5mm. Further, the unadhered parts 4 are so provided as to exist in the positions symmetrical with the A surface side and the B surface side. The resonance frequency decreases drastically when the length Y of the unadhered parts 4 exceeds 10mm. The oscillation amplitude of the disk is suppressed to a low level in this way.

Abstract: PURPOSE:To prevent leakage of water with the curtailment of the number of parts by a method wherein an output shaft of a small motor and a valve are linked with a flexible link member to provide a quickly closing operation mechanism on the side of the output shaft. CONSTITUTION:A small motor 19 is provided to open or close a valve made free to slide on a drain valve 11 and a spring 18 to press the valve 16 in the direction of closing it. The valve 16 is linked to an output shaft 19a of the small motor 19 with a mobile link member 17c of a valve shaft 17. A hook part 17d is formed on the link member 17c and a lever 24a of a base 24 is engaged therewith. In this manner, as the valve shaft 17 is provided with the mobile part 17c, a pull string can be eliminated and also, as the valve is closed at a speed depending on a return rate of a push spring 18, the draining of a lip part 16a and a valve seat is improved to upgrade a closing property. Moreover, the curtailment of parts and the simplification of the assembling enables the obtaining of an inexpensive drain valve 11.

Title: Neon glow discharge lamp and lighting system using it
Inventor: TAKAGI MASASANE
IPC: F21V7/00
Filed: 1994-09-30
Abstract: PURPOSE: To provide the neon glow discharge lamp, which can improve the starting ability and which can stabilize the positive column, and a lighting system using it by using an auxiliary electrode. CONSTITUTION: Neon gas at 30-120Torr is sealed in a bulb 1, in which main electrodes 2 are sealed, and an auxiliary electrode 5 is provided on the outer surface of the bulb 1 along the tube axial direction. Consequently, since the electrical potential is given to the auxiliary electrode 5, discharge is induced between the auxiliary electrode and the main electrodes, and the starting voltage is thereby lowered. At the time of lamp lighting, an electric field is generated near the auxiliary electrode, and this electric field positively attracts the positive column, and the positive column is thereby attracted to the auxiliary electrode side so as to prevent the generation of distortion and oscillation (snake phenomenon) of the positive column, and discharge is thereby stabilized.

Title: Fault detection and selection circuit
Inventor: OTAKI SABURO
IPC: G06F11/22
Filed: 1985-10-25
Abstract: PURPOSE:To detect a fault with attachment/detachment of a small number of minimum units and to improve the maintainability of a fault detection/ selection circuit, by selecting test data in the following machine cycle when a fault is detected and also holding the presence or absence of generation of a fault at that time point. CONSTITUTION:A selection means 6a of a minimum unit 3a selects a minimum unit 1 or 2 via a selection condition changing means 10 which works in response to a selection circuit 300. The output of the selected unit 1 or 2 is supplied to a fault detecting circuit 7 for detection of the generation of a fault. The result of this detection is held by the 1st holding means 8. Then the means 10 is controlled by the means 8 and the means 6a selects the output of a test data setting means when a fault is detected. In the same way, the result of detection given from the circuit 7 is held by the 2nd holding means 9. Thus the fault of the unit 1, 2 or 3 is decided by the contents of both means 8 and 9. This attains the detection of faults with attachment/detachment of a small number of minimum units and improves the maintainability of a fault detection/ selection circuit.

Title: Controller for engine with automatic transmission
Inventor: YOSHIMURA HIROSHI
IPC: B60W10/06
Filed: 1988-09-26
Abstract: PURPOSE:To prevent excessive decrease in engine output, and to obtain smooth shift-up by not executing the decrease of the engine output that is concomitant with the shift-up when the estimated engine speed after the shift-up is not more than a predetermined value. CONSTITUTION:At a control unit U1 for transmission, the decision whether the transmission is executed or not is performed based on a predetermined transmission characteristic, and a transmission command signal, that is, a shift-up signal or a shift-down signal is output. A delay angle request signal of ignition timing is output to a control unit U2 for controlling the ignition timing by the control unit U1 at a predetermined timing after the transmission command signal is output. Only when the shift-up is to be executed, prerequisites for the execution of the delay angle include that the estimated engine speed after the shift-up is greater than a predetermined value, for example an equivalent to the idling speed. For the decrease in the engine output during the shift-up, some methods are to be taken properly such as the execution of the delay angle of ignition timing, the change of the air-fuel ratio or making it lean, or by forcing a throttle valve altered to closing direction.

Title: Process for producing article containing heat resistant dielectric object
Inventor: FLEMING JR JAMES WILLIAM
IPC: C03B37/014
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To greatly improve the smoothness of heat resistant dielectric objects and more particularly silica sol-gel objects by a relatively simple treatment by treating these objects with plasma fire balls in such a manner that their roughness is lowered without largely removing the surfaces. SOLUTION: The dielectric objects, such as quartz over-cladding tubes and silica core rods, are heated by using the plasma fire balls, by which the smoothness of the objects is improved. The roughness of the over-cladding tubes measured by RA may be lowered by at least twice. Generally, the roughness is lowered down to RA below about 1 microinch of the silica objects. A gas supplying source 17 supplies the gas used for plasma discharge to a mantle 11 where the plasma fire balls 12 are excited by an RF coil 19 and an RF generator 14. The fire balls 12 are included in a torch 10 and the center 16 of the fire balls 12 exists at the center of the RF coil. When the heat resistant dielectric object 20 is a cylindrical optical fiber, this object is installed in a race 21 capable of rotating the same during the treatment.
