Title: Vacuum chuck for wafer and method of manufacture thereof
Inventor: TAKEMURA FUMIHIRO
IPC: H01L21/68
Filed: 1991-04-23
Abstract: PURPOSE:To make the suction of a wafer desirable by forming a chuck itself with a conductive ceramic. CONSTITUTION:A vacuum chuck for a six-inch wafer is prepared by forming a suction surface with a complicated supporting pattern machined by electric discharge on one side of the body of a disc chuck having a diameter of 140mm made of TiB2, for example. Then, when this vacuum chuck is used in a stepper (aligner) for chucking a silicon wafer, the chuck body presents a high abrasion resistance compared to a vacuum chuck made of aluminum alloy. It also shows less changes in the elapsed time. Hence, an excellent abrasion resistance and the precision required for the suction surface can be maintained for a long time. The suction surface can be easily machined, at the same time making it possible to prevent the adhesion of dust particles to such a surface due to static electricity.

Title: Method and device for negative film and photosensitive member contacting for exposing machine
Inventor: SASAGE KAZUNORI
IPC: G03F7/20
Filed: 1988-05-18
Abstract: PURPOSE:To eliminate the need for hand operation and to automate the exposing machine fully by bringing a negative film into contact with a photosensitive member in a radiation direction in sequence when the negative plate film is curved in a center high state together with a transparent holding plate, pressing against the photosensitive member, and flattened. CONSTITUTION:While a packing 15 abuts on the top surface of a glass plate 4, the sealed space between the glass plate 4 and a suction plate 4 is evacuated and reduced in pressure through a suction casing 13 and a suction pipe 12 from remaining air suction holes 16, 16... which are not closed with a printed board P, so that the glass plate 4 curves and deforms together with the negative plate film F so that the center part swells. Simultaneously, a carrier head is lowered continuously and the reverse surface of the printed board P contacts the peak surface of the negative plate film F. When the carrier head is further lowered continuously, the glass plate 4 is pressed by the suction plate 14 across the printed board P together with the negative film F and restores itself to a flat shape while brought into contact with the reverse surface of the printed board P in the radiation direction in sequence from the curved peak surface, so that the reverse surface of the printed board P is brought into contact with the negative plate film F entirely and completely. Consequently, the complete contacting is performed without any operator.

Filed: 1985-05-31
Abstract: PURPOSE:To perform switching in accordance with the characteristic of an original picture by providing a density change detecting means which detects a picture element, which has a small spatial density change between the picture element itself and nearby picture elements, from picture elements belonging to a double read part of plural image pickup elements and using the detected picture element as a switching picture element. CONSTITUTION:Image pickup outputs of two CCD line sensors 11a and 11b which read the original picture divisionally are stored temporarily in memory blocks Ma and Mb and are joined in serial thereafter by a selector 23 with the picture element, which is detected by a density change detector 17 and has a minimum density change value, as the switching picture element to become a reproduced picture signal Sout, and this signal is outputted to a picture processor in the succeeding stage. A comparator 22 compares an address AR in a latch circuit 18 with an output A3 of a read address generator 19; and if the address AR is larger than the output A3, the selector 23 is allowed to select its A input and outputs it as the reproduced picture signal Sout. Thus, the switching position between image pickup elements is changed in accordance with the characteristic of the original picture, and disturbance of the reproduced picture is made difficult to recognize.

Title: Fuel cut-off method of electronic fuel-injection internal combustion engine
Inventor: TOMITA KAZUO
IPC: F02D41/12
Filed: 1981-08-03
Abstract: PURPOSE:To prevent abrupt change in power by estimating a decelerated condition and then maintaining an injection ratio represented by quantity or period for a certain interval from the cutting-off starting point of fuel supply to its completion that a misfire will not occur and the quantity of the injection may be made slightly more than that of the injector's irregular injection. CONSTITUTION:A computer 5 estimates the decelerated condition on the criteria that an idle switch 2 is on, an engine speed is decelerated and the engine speed is lower than a fixed value at which fuel is to be cut off. Fuel cut-off based on the estimation is performed in such a manner that injection is maintained at a present ratio taun represented by quantity or period for a certain interval Tc from the estimation point To, if the taun is lower than the minimum capacity taumin of an injector, injection is executed at a ratio taum which is provided as a function of the engine speed for an interval (Tc-Tm), and injection is executed at a  ratio taun and the fuel is then completely cut off. In another case of (taun=taumin)  fuel is injected at a rate taun during a certain interval Tm before fuel in cut-off.  Since an abrupt change in power and fluctuation in pulses will not occur, a  shock or a surge of the vehicle may be prevented.

Title: Pipe body inserting device
Inventor: IDEMOTO IWAO
IPC: B21D53/06
Filed: 1979-09-21
Abstract: PURPOSE: To insert long-sized pipes into the devie without damaging and improve working efficiency by grasping the pipes with revolving rollers and retaining rollers and changing the revolutions of the rollers accroding to the inserted load.  
     CONSTITUTION: When a hydraulic motor 12 is operated by turning a switch 13 ON, drive rollers 15 are revolved by way of gears 14. When the end of a pipe 8 reaches the drive roller 15a and retaining roller 16a, an arm 21 turns around a pin 19 and grasps the pipe 8. Further, when the pipe 8 reaches the succeeding drive roller 15b and retaining roller 16b, the roller 16b is forced upward. This causes the slide plate 17 supporting the arm 21 to move upward so that a uniform pressing force is given to the rollers 16a, 16b by a spring 18. Next, the rotating speed of the drive roller 15b is changed in correspondence to the inserted load resistance at the insertion of the pipe 8, whereby the exertion of a large load upon the pipe 8 is obviated.
