Filed: 1988-06-23
Abstract: PURPOSE:To prevent occurrence of an abnormality in carrying by arranging 1st and 2nd read means respectively at both sides of the carry path through which the original is carried so as to read both sides of the original carried through the carrying path. CONSTITUTION:With an original O' an original O' having read information described on both front and rear faces placed to a paper feed tray 11, when double side read is commanded, an optical system 5 is moved from the initial position S in a direction of arrow (b) till a position P opposite to a platen roller 15. When the original O' comes to the position P of the platen roller 15, its rear side is read by an optical system 21 and then the front face of the original O' is read by the optical system 5 when the original O' comes to the position of the platen roller 17. Thus, the mechanism reading both sides of the original is simplified and the occurrence of an abnormality of carrying is prevented.

Title: Semiconductor manufacturing device
Inventor: MITSUI SHINJI
IPC: H01L21/30
Filed: 1989-06-16
Abstract: PURPOSE:To facilitate removal of scums and residue at pattern edges by providing an aspirating nozzle with an ultrasonic vibrator. CONSTITUTION:An aspirating nozzle 3 which produces an atomized developer 6 is equipped with an ultrasonic vibrator 7. When pressurized nitrogen, inactive gas, and the developer are mixed and formed into atomized particle shapes, the developer 6 receives kinetic energy which is obtained by converting vibration energy from the ultrasonic vibrator 7 into kinetic energy in addition to having kinetic energy as a result of pressurizing nitrogen and inactive gas. Eventually, the atomized developer 6 which has kinetic energy exceeding conventional kinetic energy beats the surface of a resist 4 heavily and its beating accelerates the rate of development. This blows off scums and residua easily at pattern edges in terms of physico-chemical treatment.

Abstract: PURPOSE: To prevent sticking of tar to a vaporizing section of a liquid fuel combusting apparatus, by dripping liquid fuel to a position located at one end of an annular vaporizing chamber, causing film boiling of the liquid fuel by heating the temperature on the internal surface of the vaporizing chamber, and ejecting mixture gas in an annular form from the vaporizing chamber.  
     CONSTITUTION: When the surface of a vaporizing section 24 is heated to the film boiling temperature region (about 220°CW350°C) by a sheathed heated connected to an electric power source, fuel supply from a fuel supply pipe 21 is started and a motor 4 is set into operation. Fuel dripped downward from the fuel supply pipe 21 is splashed and vaporized, and then carried toward an opening 20 along with primary-air flow from an opening 18, so that the vaporized fuel is mixed with primary-air. The mixture of fuel and primary air is carried from one side of a partition wall 17 extended across the vaporizing section 24 toward opening 20 on the other side of the partition wall 17. Then, the air-fuel mixture is introduced into a mixing chamber 15, in which its pressure is equalized by a pressure equalizing plate 26, and issued to the outside from a flame forming plate 27. When the mixture is ignited, it is combusted together with secondary air supplied from secondary- air supply passages 12, 12'.

Abstract: PURPOSE: To smoothly raise and lower a pane for car by bearing a slider sent up and down with rotation of a vertical linear feed screw on a glass bracket bearing the curved pane in a movable manner in the direction of the arrangement of the feed screw and pane. CONSTITUTION: A guided pin 18 projected from both right and left sides of a slider 11 is interlocked with a longitudinally long guide hole 10 formed in a glass bracket 7, and the slider 11 is slidable and turnable against the bracket 7. Then, even if an interval between the screw 2 and a pane 19 is varied, because an interval between a site interlocking the slider 11 with a thread groove of the screw 2 and the pane 19 varies, it can correspond with the interval between the screw 2 and plane 19. Then, since the slider 11 is turned against the bracket 7, it can correspond with variations in an angle of the pane 19 against the screw 2. By this constitution, the pane can be smoothly raised and lowered, the screw can be used without taking its strength into consideration because of using the linear screw, and large curvature can be provided thereto.
