Title: Optical system driver
Inventor: KOBATA YOSHIHIRO
IPC: G02B26/10
Filed: 1986-04-17
Abstract: PURPOSE:To attain the proper tracking control without requiring large sized device by forming a support provided to be deformed in the tracking direction only by a one rubber elastic plate at the tracking control. CONSTITUTION:In moving an objective lens 12 in the tracking direction B-B' to apply tracking control, a lens holder 10 is moved in the tracking direction B-B' by the magnetic interaction between the magnetic field caused by applying a current to tracking coils 22a, 22b in either proper direction of the arrow C and the magnetic field caused by magnets 26b, 26d to attain the tracking control. Since one rubber elastic plate is used for the support 28, the same degree of deformation as a conventional driver is formed by using nearly a half external force in comparison with a conventional type driver.

Title: Control device for fuel injection of internal combustion engine
Inventor: SONODA YUKIHIRO
IPC: F02D41/10
Filed: 1988-04-08
Abstract: PURPOSE:To prevent the large fluctuation in an air-fuel ratio to an excessively dense side and a lean side by correcting an acceleration increase value and speed reducing value by reducing according to the rise and fall of a rotating speed. CONSTITUTION:The acceleration increase value calculated by a fluctuation calculating means M5 is corrected by its reduction according to the rise of the rotating speed detected by a running state detecting means M2. On the other hand, the correction means M7 connecting a speed reduction value by reducing according to the fall of the rotating speed is provided. The acceleration increase and speed reduction decrease at speed increasing and decreasing times can thus be corrected to the optimum value corresponding to the rotating speed, so the large fluctuation to the excessively dense side and lean side in an air-fuel ratio caused by the acceleration increase and deceleration decrease can be prevented.

IPC: F04D29/54
Filed: 1995-04-13
Abstract: PURPOSE: To make the promotion of low noise achievable while diffusing those of characteristic turbulent noises and discret-frequency noises inherent in an air blower to other frequency zone by installing plural pieces of blades in and around a hub part attached to a motor, and setting up these blades in an orifice whose inner circumferential part is oval. CONSTITUTION: A motor shaft is locked to a hub part 1 installed with blades 2, while these blades 2 are housed in an orifice 6 of which inner circumferential part 5 is formed into an oval, and they are rotated in the arrow direction, whereby a blast action is produced. Air flows in from each front edge part 7 of the blades 2 and then flows out of each rear edge part 8, performing an aerodynamic job. In this case, the inner circumferential part 5 of the orifice 6 is formed into an oval, and thereby an axial symmetric property in this blower is made to come off in consequence. Therefore, those of characteristic turbulent noises and discrete-frequency noises inherent in the blower are diffused wide, through which these noises can be held down to a low noise level.

Title: Manufacturing apparatus for semiconductor device
Inventor: FUJIE KOJI
IPC: H01L21/22
Filed: 1987-04-09
Abstract: PURPOSE:To prevent fine particles and the air outside a reaction tube from being dragged into the reaction tube by a method wherein the gas in a gap between the reaction tube and an external tube is sucked by a vacuum pump and a wall of air current is formed above the opening of both the tubes. CONSTITUTION:As a gap 5 is maintained at a negative pressure by a vacuum pump, the outside air near an opening 3 forms air current toward the gap 5 to form a wall 12 of air current which covers the opening 3 of a reaction tube 1. Further, flow 14B of reactive gas, for instance nitrogen gas, near the inner wall of the reaction tube 1 is dragged into the wall 12 of air current and makes itself a part of the wall 12. Therefore, the outside air and fine particles from the outside are all dragged into the wall of air current and exhausted out through the gap 5 so that dragging of the outside air and the fine particles from the outside into the reaction tube 1 can be avoided.

Filed: 1985-04-26
Abstract: PURPOSE:To make the floating quantity of an inner peripheral rail coincident with that of an outer peripheral rail by setting up the floating pressure generating ability of the outer peripheral rail smaller than that of the inner peripheral side. CONSTITUTION:It is supposed that the center rail 8 of a slider 2 is located on the center D of a disk and floats at the time of a rotating speed (n). When it is defined that a gap between the inner peripheral rail 6b and the outer peripheral rail 6a is W, the floating quantity of the rail 6b is gb, its disk speed is Vb, the floating quantity of the rail 6a is ga, and its disk speed is Va, equations (1), (2) are satisfied when the width of the rails and a peripheral speed are fixed respectively. In this case, the difference between the floating values based upon the peripheral speed shown by equation (1) is compensated by the difference between the effective width (B-alphaw)of the rails which is shown by equation (2) to make the floating values of the inner and outer peripheral rails 6b, 6a equal. Namely, the ratio of the effective width (B-alphaw) of the inner and outer peripheral rails 6b, 6a is selected within a range shown by equation (7) by using the diameter D of the disk and the gap W between the rails.
