Title: Detecting method for mark position in electron beam exposure
Inventor: TAKEMURA HITOSHI
IPC: H01L21/30
Filed: 1981-05-09
Abstract: PURPOSE:To shorten a mark detecting time by emitting an electron beam twice while crossing two line segments when providing two line segments crossing with a semiconductor wafer each other, emitting the electron beam to the wafer to detect the mark position coordinates, thereby obtaining four crossing point coordinates by the twice emissions. CONSTITUTION:Marks M1, M2 of two line segments crossing with each other are formed at the peripheral edge of a semiconductor wafer 1, an electron beam is emitted to either mark, thereby detecting the mark position coordinates. At this time, the electron beam is ordinarily emitted in parallel with the line segments a, b. However, this is improved to cross the electron beam across the segments a, b as designated by an arrow 2 when the first emission is performed, thereby simultaneously obtaining crossing points A, B. When second emission is then performed, the emitting direction is displaced to a direction as designated by an arrow 3, and the crossing points C, D of the segments a, b are obtained at other positions. Thus, the four times scanning can be reduced to twice, and the mark position detecting time for drawing the electron beam can be shortened.

Abstract: PURPOSE:To alternate optical fibers with a low loss in a short time by providing a concave mirror, variable in inclination through driving mechanisms, in the optical  path of one optical fiber, and by arranging optical fibers to which light reflected by  the concave mirror is made incident. CONSTITUTION:A luminous flux 8 emitted from an optical fiber 8 is reflected by a concave mirror 9 and focused on one of six optica fibers 11a-11f arranged around the optical fiber 8. For example, one driving part 10a among three driving parts 10a-10c arranged behind the concave mirror 9 pushes the concave mirror 9, so that the reflected light is made incident to the fiber 11a. When solenoids 10b and 10c are driven simultaneously, the reflected light is made incident to the optical fiber 11d. Similarly, optical fibers 8 and 11 are also alternated with a low loss in a short time.

Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of the reflected wave in a discharge container and enable the high density and uniform plasma to be generated efficiently. SOLUTION: At the end section of a discharge tube 10 having a cavity section 10A, a wave guide tube 2 giving a micro wave and a micro wave cavity wall 5 and the like are provided, in a emission device connecting a surface wave by a micro wave from a surface wave connecting section 7 to the discharge tube 10, a lead wire 12 is arranged along the longitudinal direction of the discharge tube 10 in the said discharge cavity section 10A, a magnetic field perpendicular to the electrical field of the surface wave is given by feeding the prescribed current to this lead wire 12 from the direct power source.

Inventor: NIKAIDO AKIRA
IPC: H02P8/14
Filed: 1985-04-02
Abstract: PURPOSE:To effectively suppress a heat generation by controlling a pulse train for driving a stepping motor to an H level at starting time and to an L level at start initiating time. CONSTITUTION:A 12V pulse is used as the starting pulse 100-1 and the stopping pulse 100-9 of a motor, and a 6V pulse is used as the operating pulses 100-2, 100-3...100-8 after the motor is started and initiated.

Abstract: PROBLEM TO BE SOLVED: To control a gear ratio as per a driver's intention by forcibly shifting up a gear ratio without any manual operation, when a condition for the occurrence of overspeed is discriminated with an over speed judgment means. SOLUTION: A gearshift lever 8 is kept at a neutral position at all times in the gate 10 of a manual shift mode, and the motion of the gearshift lever 8 by a driver's operation is detected as an instruction. A map saves a travel speed and an accelerator opening condition for shifting up a gear ratio from the first gear to the second gear, the from the second gear to the third gear, and sets a condition for shifting up a gear ratio at a higher speed in the low accelerator opening. When a condition for the accelerator opening in the first gear state is found at a high speed above a gear ratio change line for the first to the second gears, the necessity of a forcible gear ratio change to the second gear is discriminated, and a forcible shift-up process is implemented without resorting to a driver's operation. Thus, a shift characteristic as per the driver's intention can be provided.

Title: Movable vane pump
Inventor: YAMADA MASAYUKI
IPC: F04D29/18
Filed: 1981-05-13
Abstract: PURPOSE:To simplify the structure and to facilitate the assembling and the disassembling, by mounting a lubrication-free bearing member at the sliding section of the impeller bearing while applying the gas pressure in the impeller thereby preventing the intrusion of the water into the impeller seal section. CONSTITUTION:The lubrication-free liners 30, 31, 32 such as the synthetic resin liners are mounted on a stem shaft 2. The pressurized air is fed from an air pipe 39 and encapsulated in a gas pressure chamber 40, thereby the oil leaked into the gas pressure chamber 40 is returned again into the pressurized oil chamber 21 by means of the pressurized air in the gas pressure chamber 40. Since the gas pressure will continuously prevent the intrusion of the water from the outside, and functioning onto the shaft sealing device 38 and the impeller seal 4, the water will not intrude. In such a pump where the pneumatic pressure is functioned onto the impeller seal 4 and the shaft sealing device 38, the small amount of air leak can be allowed thereby the structure can be simplified. Consequently the impeller hab can be made thin while the interior of the impeller boss can be widened resulting in the facilitation of the assembling/disassembling and the reduction of the size.

In this way, an induction voltage at switching operation can be reduced.

Title: Antiskid control device
IPC: B60T8/58
Filed: 1992-03-27
Abstract: PURPOSE:To shorten a brake distance and to improve cornering control performance during brake by performing antiskid control according to distribution of a load classified by a wheel. CONSTITUTION:A control device 1 performs antiskid control of a brake device 5 through an oil pressure control device 4 by means of signals from a wheel speed sensor 2 and a stroke sensor 3. Antiskid control is effected such that, based on a wheel speed signal from the wheel speed sensor 2, a force by which a brake pad 6 holds a brake disc 7 is regulated so that each wheel is prevented from locking. In a state that a wheel is in a levitating state, a wheel speed is decreased even in a state that a holding force is low. When it is decided by means of a signal from the stroke sensor 3 that the wheel is levitated, it is decided that the wheel is not in a locked state, lowering of a brake oil pressure is stopped and an enough brake force is generated.

Abstract: PURPOSE: To obtain a digital IC inspecting device which reduces the frequency of inspection to one by deciding on multiple-valued levels at once by using comparators.  
     CONSTITUTION: In general, 2N-2 criterion voltages and comparators are required for N-valued output level inspection, encoder outputs are minimum M signals where 2N-1≤2M, and M-1 expected value pattern signals are necessary.

Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling an electronic blackboard device, capable of printing with multicolor and improving the usability of the device. SOLUTION: In a relationship between the pulse width of strobe signal to be applied to a thermal head for forming an image on a multicolor thermosensitive recording paper and coloring on the multicolor thermosensitive recording paper, within the range that the pulse width is from (a) to (b), the multicolor thermosensitive recording paper colors into black, and within the range that the pulse width is >=(c), the multicolor thermosensitive recording paper colors into red. Note that, within the range that the pulse width is from (b) to (c), the red coloring layer of the multicolor thermosensitive recording paper does not operate until it is recognized as red, and a color intermediate between black and red, i.e., brown is colored. Thus, by first recording the resulting data of the OR of the black image and the red image and then recording the red image data, the images of the three colors, white, black and red, are recorded, and the pulse width of 2nd strode signal, at the time of recording the red image, is reduced.
