Title: Amplifier circuit
Inventor: TSUCHIYA KENICHI
IPC: H03F3/45
Filed: 1985-06-07
Abstract: PURPOSE:To obtain an output signal in response to the leading of an input signal from OV by constituting an amplifier to which an input signal is applied by PNP transistor (TR). CONSTITUTION:The PNP TRs Q1, Q2 constitute an amplifier. TRs Q3, Q4 reduce an offset voltage of TRs Q1, Q2. Further, a reference voltage Vref, TRs Q5, Q6 and resistors R4, R5 constitute a constant current circuit. A voltage V1 is an input signal to the amplifier and when the voltage level of the voltage V1 rises from OV, the voltage VA rises in response to the level change. Then the voltage VB also rises, a TR Q7 is turned on to feed back negatively a current in response to the level change of the voltage V1 to a base of the TR Q2 via a diode D1. An output signal V0 is obtained by the voltage drop of a resistor R6 and stabilized by a capacitor C1.

Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To improve the throughput of an aligner by securing overlay accuracy without correcting the magnification of projection onto a wafer for every wafer by measuring the temperature of the wafer in exposing the wafer and correcting the projection magnification based on the measured temperature. SOLUTION: After the pattern of a mask 7 is aligned with a work 3 in accordance with an exposure sequence, the magnification of the work 3 is measured and exposure is performed while the magnification of the work 3 is corrected, based on the measurement results. The measured magnification is registered in an aligner as a reference magnification. Then the next work 3 is carried onto an exposure stage 2 by means of an interface arm and, at the same time, the temperature of the work 3 is measured by means of a sensor 6a and stored.  When the measured temperature falls within a tolerance, exposure is performed while the magnification of the work 3 is corrected, based on the stored reference magnification and the difference between the measured temperature and the registered reference temperature, without measuring the magnification of the work 3 after aligning the pattern of the mask 7 with the work 3.

Abstract: PURPOSE: To effectively prevent the occurrence of an acceleration spin by a method wherein braking is effected by an initial control brake power having a value increased in a decided ratio from a schedule of a given ratio and when a given wheel state representing an initial wheel spin restoration state is sensed, the braking is completed. CONSTITUTION: A traction controller 36 is provided to limit the acceleration spins of front wheels (driven wheels) 10 and 12 due to excessive engine output torque. When the occurrence of the spin is decided from outputs from speed sensors 39-42, the spin is prevented from occurring by operating the brakes 18 and 20 of the front wheels 10 and 12 and throttling the opening of an auxiliary throttle valve 38. In this case, braking is effected by an initial control brake force having a value increased in a decided ratio from a schedule in a given ratio as a function of the value of an engine torque related parameter. When a given wheel state representing an initial wheel spin restoration state is sensed, the braking is completed.

Title: Decorating method with fine ice
Inventor: IOKA MASAYOSHI
IPC: B44C5/06
Filed: 1989-05-17
Abstract: PURPOSE:To make atomized ices with fine ices by a method wherein atomized fine water having a specified particle diameter is injected against an ice supporting column and at the same time the supporting column is placed under a cold air flow of a specified temperature. CONSTITUTION:Injected water drips 9 are injected or atomized under a distribution of dried ice fine particles through a mixing with the atomized water or under a by mixing the cold gas such as cooling air or the like with the atomized or injected water and by placing the supporting column 3 in the cold air stream of -10 to -50 deg.C. After the atomized water drips 9 are adhered to the supporting column 3, it is necessary for the water drips to reach the supporting column 3 under an over-cooled state. Due to this fact, in case that the particle diameter of the water droplets is more than 100mum, only the water droplets of fine particle diameter are partially iced under a relative high temperature such as -10 deg.C. Accordingly, even in case of a relative high temperature, the atomized water droplets 9 are atomized as 10 to 100mum in order to provide an efficient production of atomized ices 11. In case of a size less than 10mum, the efficiency is reduced due to a low adhering rate against the supporting column 3.

Inventor: YAMAZAKI HARUYUKI
IPC: F01K25/00
Filed: 1983-07-08
Abstract: PURPOSE:To aim at a reduction in plant power without necessitating any power for hydraulic fluid circulation, by combining a plural-step bubble booster pump, which installs a hydraulic fluid suction pipe in a lower drum at the first step and an exhaust pipe in a condensing chamber at the final step, respectively, with an evaporator, a turbine and a condenser. CONSTITUTION:A hydraulic fluid being liquefied in a condenser 5 is led into a bubble booster pump 7 at the first step and heat-exchanged with a heat source fluid system 102. Then, air-liquid separation takes place at a condensing chamber 11, while vapor is liquefied and fed to a lower drum 15 at the next step. After similar operations are repeated at each step in regular sequence, the hydraulic fluid in the condensing chamber 11 at the final step is led into an evaporator 2 and, after a turbine 3 is rotated by the steam, it is liquefied again at the condenser 5. Thus, since a circulating pump can be made into useless, it can dispense with pumping power any longer.

Title: Doubling controller
Inventor: INABA KOUICHI
IPC: G05B7/02
Filed: 1982-07-13
Abstract: PURPOSE:To ensure a bumpless switch between primary and secondary systems, by performing the digital control for both a controller for the primary system which generates a control pulse for an object to be controlled and a controller for the secondary system which generates the control pulse in place of the controller for the primary system when it has a fault. CONSTITUTION:An arithmetic part 7 calculates a deviation between the control target value A and a feedback value B while a primary system controller 1 is operated in an automatic mode. A control part 10 generates control pulses D to increase/decrease the displacement of a control terminal 5 until the above-mentioned deviation is set at 0. A pulse/air converter 4a controls the terminal 5 in response to the pulse D, and the displacement of the terminal 5 is fed again to the part 7 as the value B. When the controller 1 has a fault, the controller 1 is immediately switched to a secondary system controller 2 to maintain the same control as the controller 1. In case the controller 2 also has a fault, the operation is changed to a manual mode to operate another secondary controller 3. Then the value B displayed at a potentiometer 6 is monitored, and a switch 11 is controlled so as to set the deviation to the value A at 0. Thus a pulse generator 12 generates a pulse D. In this case, the converter 4a maintains the terminal 5 as it is until the pulse D is reset.
