Title: Quick-disconnect procedure control of terminal on power distribution panel and device therefor
Inventor: AREN JIEE BAANAADEINI
IPC: H01R13/639
Filed: 1990-07-10
Abstract: PURPOSE: To connect a plurality of plugs with outlets in proper procedure by forming prescribed fixed notches on the surface of cam rings surrounding the outlets in the case plugs are connected with outlets by rotating the plugs in one direction. CONSTITUTION: A cam ring 11 which surrounds an earth outlet 21 can be rotated clockwise or counterclockwise since the cam surface 16 can freely rotate relative to a fixed notch 18 on a ring 12. On the other hand, the cam ring 12 can not rotate freely since a fixed notch 18 is adjacent to the fixed notch 18 on the ring 12. In the same way, the fixed notches 18 on rings 13-15 have neighboring relation with the cam surface 16 in the next left side. When the ring 11 is turned about 45 deg., the cam surface 16 of the ring 12 passes a gap notch 17 of the ring 11, so that ring 12 freely rotates and the rings 13-15 rotate in the same manner. Consequently, plugs in series which are to be rotated as to be connected with outlets in series can be connected with outlets 21-25 only by such procedure from the left to the right.

Inventor: ITO YOSHIKI
IPC: F02D9/02
Filed: 1993-07-22
Abstract: PURPOSE:To prevent the idling engine speed after speed reduction from excessively becoming high due to the malfunction of a dashpot, in a double valve type throttle body. CONSTITUTION:In an opening being lower than a prescribed low-opening, the opening reducing speed of a main valve 13 is restricted by a return speed restricting means 17 to a value not causing engine stalling, and a control unit 20 controls an auxiliary valve 14 via a servomotor 22 so that it has the same opening as the main valve. When it is judged by a first judging means 1 that the opening of the main valve is less than a predetermined low opening, a valve opening reducing speed detecting means 2 detects the main valve opening reducing speed. When it is judged by a second judging means 3 that this reducing speed is less than a normal reducing speed due to the return speed restricting means, an auxiliary valve closing means 4 reduces the opening of the auxiliary valve via the servomotor by a speed that has been previously determined inpendently of the opening of the main valve.

Filed: 1980-12-22
Abstract: PURPOSE:To improve the efficiency and simplify the mass production of optical circuits by covering the whole surface of a base material with a sensitive glass layer and executing masking, exposing and etching removal to form optical paths having a prescribed pattern. CONSTITUTION:A sensitive glass layer 2 with even thickness is formed on almost all the surface of a base material 1 such as a quarz glass plate by a well- known film forming procedure. The surface of the sensitive glass layer 2 is masked 3 with a nontransmittable material so as to cover only the parts remaining as optical paths. Ultraviolet rays 4 are vertically irradiated over the masking parts 3 for a fixed period with an optical system and then a prescribed heat treatment is carried out to deposit crystal on the exposed part 2A of the sensitive glass layer 2. Then the exposed part 2A is etched with dilute hydrofluoric acid solution to remove the exposed part 2A. Thus, optical paths which are composed of sensitive glass having a prescribed pattern and have high section forming accuracy are formed on the base material 1 efficiently.

Abstract: PURPOSE:To preheat combustion air, introduced into an air preheater, through a simple structure, by a method wherein the downstream position of the air preheater in an air duct and the upstream position of a forced draft fan in the same duct are connected through a circulating duct having a regulating damper. CONSTITUTION:An average temperature is obtained in an average value operator 11 by detecting temperatures obtained by thermometers 9, 10 and the average temperature is compared with a set temperature signal 12 in a comparator 13. When the average temperature is lower, a driving device 7 is operated by a controller 14 to increase the opening degree of a regulating damper 8.

Title: Handling of wafer and processing system
Inventor: ROBAATO SHII ABE
IPC: H01L21/68
Filed: 1995-06-07
Abstract: PURPOSE: To make feasible corrective measurement before the processing oversteps the control or regulation limit by a system which pairs with a data network capable of serveying trouble positions in a wafer processing as a whole, utilizing correlation between actual data information and wafer processing simulation. CONSTITUTION: This system provided with a vertical wafer processor 10 is in contact with only a wafer edge part. Therefore, when a wafer is handled vertically, air runs vertically passing through the wafer, thereby partially reducing the pollution by fine grains. Furthermore, the distortion of a semiconductor wafer probably due to the gravity thereon, when handled horizontally can be diminished by handling it vertically. In such a constitution, if the contact is limited to the edge part of the wafer, latent harmful effects due to contact such as pollution of damages can be counteracted favorably. Furthermore, if a wafer edge part is handled, both sides of the wafer can be included in the effective range of the measurement.

Title: Method and apparatus for screen printing
Inventor: SATO SHOJI
IPC: B41F15/40
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent a decrease in printing accuracy caused by following movement of a screen mask to a matter to be printed when the matter is to be separated from the mask. SOLUTION: A squeegee 8a is slid on a screen mask 1, cream solder is charged in a printing pattern opening formed at the mask 1, then a base plate 2 is separated from the mask 1 by driving a base plate holding bearer 3, and the solder charged in the opening is transferred onto the plate 2. The mask 1 is held at a predetermined position by a holding member 4 so that the mask 1 does not follow to movement of the plate 2 at the time of separating the plate 2. Thus, since no deformation or positional deviation occurs at the solder transferred to the plate 3, highly accurate screen printing can be executed.

Abstract: PURPOSE:To achieve a long life of a device by coating a tube internal surface, except a slit-shaped location along the tube axis of a mercury lamp, with a selective optical film for reflecting light in an ultraviolet region and further for permeating light in an infrared region, so that light of the mercury lamp is efficiently used to reduce a lamp current. CONSTITUTION:In a mercury lamp 11 stored in a lamp house 2 of a lamp light source 12, a slit-shaped location (m) along a tube axis corresponding to an opening slit 9 orthogonal to the tube axis is provided in the central part of a luminous part 13. A tube internal surface of the mercury lamp 11 except this location (m) is coated with a selective optical film 14 for reflecting light in an ultraviolet region and further for permeating light in an infrared region. Accordingly, light La from the luminous center 0 of the luminous part 13, with light Lb in the ultraviolet region reflected by the film 14, arrives at a photosensitive film in the internal surface of a face panel 4 through the slit 9 and a correcting lens 5. Thus by effectively using light in the ultraviolet region necessary for exposure, a lamp current is reduced, and extending a life of the mercury lamp 11 can be attained.

Title: Optical scanning device
Inventor: SHIMIZU TAKUMI
IPC: H04N1/113
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To speedily reduce vibrations of an optical system accompanied with the scanning of a light beam without requiring a complicated circuit or signal processing. SOLUTION: Vibrations generated by a laser scanning unit 52 which contains a polygon mirror and a motor for driving it are mechanically amplified by a vibration detecting mechanism 53 and detected by, for example, a pressure sensor. Its detection result is inputted to an excitation control circuit 54, which applies a driving signal 55 for excitation that is in phase with respective mirror surfaces to an exciter in a laser scanning unit 52 to generate vibrations canceling the vibrations. The phase where the vibrations are reduced most is roughly found from the output of the pressure sensor and then the phase is finely adjusted. Thus, the fine-rough adjustments are made, so the phase for setting the vibrations of the optical system to the minimum is speedily set.
