Title: Output circuit
Inventor: YOKOBORI SHINGI
IPC: H03F3/30
Filed: 1979-12-28
Abstract: PURPOSE: To enable forwar-reverse two-way currents to be fed to a load by a single power source alone by using a 2-phase differential amplifier and a negative feedback circuit in an output circuit of a brushless DC motor of full-wave drive type.  
     CONSTITUTION: Hall element outputs are fed as inputs to the 2-phase differential amplifier 27 through resistors R 1 , R 3 . An armature winding 26 is connected between outputs 24, 25 of the 2-phase differential amplifier 27, and the outputs 24, 25 are fed back to inputs 22, 23 of the 2-phase differential amplifier 27 through resistors R 2  and R 4  respectively and fed back in the reverse polarity in the input/ output relation. If a gain of the 2-phase differential amplifier 27 is high enough, an output voltage V 2  is proportionate to an input voltage V 1  and the forward- reverse 2-way currents flow to the armature winding 26 according to the positive and negative natures of V 1 . The armature winding 26 is not provided with a common terminal such as a center-tap so that all of the power source voltage are effectively applied thereto.

IPC: B60T13/74
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for operating an electronic mechanical brake device to reliably apply brake on an automobile even when disturbance or a trouble occurs to a power system in a machine and stop the automobile. SOLUTION: This brake device comprises brake actuators 14a and 14b; a control unit 10; and two brake circuits 24 and 28 to receive the supply of a power from the power system in the inside of an automobile and be individually driven. When the voltage of the power system is higher than a given value, a brake device 2 is normally operated and driven, and when a voltage is below the given value, drive through emergency operation is carried out. In a case of normal drive operation, two brake circuits are driven and in a case of emergency drive operation, a brake circuit is driven until emergency power storage parts 22a and 22b attendant to one brake circuit are consumed.  The other brake circuit is driven for a long period until an energy remaining amount attains a value high enough to stop wheels 18b and 18a one time in a state that the emergency power storage part attendant to the other brake circuit stops an automobile.

Title: Discharge lamp
Inventor: WATANABE KEIJI
IPC: H01J61/54
Filed: 1979-12-28
Abstract: PURPOSE:To prevent a discharge lamp from fully lighting out by performing lighting with a hgih pressure discharge lamp as a rule and making discharge, using a discharge gap until the high pressure lamp is restarted. CONSTITUTION:A discharge lamp is connected to a power supply 25 through a ballast 24. When power voltage is applied, a high pressure discharge lamp 8 starts discharging and the current controlled by the ballast 24 is applied. After discharge is started, the high pressure discharge lamp 8 reaches the stable lighting state in approximately five minutes. Once the high pressure discharge lamp 8 has lit out due to the temporary breakdown of power supply voltage, discharge occurs between the main electrode 15 of a discharge gap 13 and its auxiliary electrode 22 and is transferred to the gap between the main electrodes 15 and 16. As a result, the discharge gap 13 reaches the stable discharge.

Filed: 1981-10-29
Abstract: PURPOSE:To improve the bitting characteristic of a rolling material and rolling efficiency by using a variable crown roll for at least one of the work rolls of rolling mills thereby increasing the rate of crown. CONSTITUTION:A detector 6 is provided on the inlet side of a rolling mill 10, and when the top of a rolling material S passes through the position where the detector 6 is set, said detector feeds a detection signal to a medium pressurizing unit 4 which operates a work roll 5 constituted as a variable crown roll (VC roll) by a prescribed time (the time until the top of the material S is bitten into the work rolls). The roll 5 bulges in a radial direction and after said roll contacts first with roughly the central part in the width direction of the material S, the roll contacts successively toward both edge directions of the material S. Thus the biting in the rolls 5 is accomplished smoothly and surely.

Title: Gap controlling method in substrate aligner
Inventor: YOSHITAKE HIROSHI
IPC: H01L21/30
Filed: 1989-07-05
Abstract: PURPOSE:To make it possible to set the upper side surface of a transparent substrate to be inspected which has irregularity in thickness, in an optimum state with respect to a mask, by obtaining a regression plate formula with respect to a curved surface formed of the upper side surface of a substrate, from the thickness data of the substrate at a plurality of suitable measuring points containing 3 points corresponding to the optical diameter on the substrate. CONSTITUTION:From thickness measured data of a plurality of measuring points P0-P4 on a substrate 2 to be exposed, a regression plane approximating most suitably a curved surface formed by the upper side surface 2b of the substrate 2 is calculated. The calculated value of the regression plane is offset on a tilt mechanism; the regression plane is made parallel with a mask plate 1; a mounting stand 4 is made to ascend by a z-moving mechanism; thus the regression plane is made to approach up to a proximity gap with respect to the mask plate 1, thereby setting the surface of the substrate 2 in the optimum state. This state is confirmed by focusing an optical system. Thereby the upper side surface 2b of the transparent substrate 2 to be inspected which has irregularity in thickness can be set in the optimum state with respect to the mask 1.

Abstract: PURPOSE:To provide a production method of a halftone phase shift mask having high accuracy for patterning in which variation of phase difference between the light transmitting through a half-shielding area and the light transmitting through a light-transmitting area is difficult to be caused. CONSTITUTION:The production of the halftone phase shift mask consists of the following processes.
