Title: Oscillator
Inventor: KOUNO KOUUN
IPC: H03B5/00
Filed: 1990-10-12
Abstract: PURPOSE:To improve performance in both the modes of a fixed oscillation mode and a variable oscillation mode by providing a variable gain amplifier, a fixed gain amplifier, an adder, and a switching means. CONSTITUTION:Now, on the assumption that a system is in the variable oscillation mode, the output of a fixed gain inverting amplifier 24 and the output of the variable gain amplifier 23 are summed by the adder 25, and summed output is fed back to the feedback input terminal of a resonance circuit 21 through a resistor R1. Accordingly, at the time of the variable oscillation mode, since the resistor R1 intervenes, the Q factor of the resonance circuit 21 is lowered, and a frequency variable range can be secured so as to be wide. Next, if the system is turned into the fixed oscillation mode, since switches SW1, SW2 are switched, an oscillation loop is formed of the resonance circuit, a phase shifter 22, the fixed gain inverting amplifier 24, and the adder 25, and the resistor R1 comes not to intervene, and since the Q factor of the resonance circuit 21 is raised, fixed oscillation frequency becomes free from dispersion, and becomes stable. Thus, the performance in both the modes can be improved.

IPC: H02J3/00
Filed: 1990-10-16
Abstract: PURPOSE:To use power load facilities to their full capacity by maintaining the power consumption of the facilities within the limit of a contract demand by reducing the power supply to prescribed power load facilities by an exceeding quantity of electric energy when the total load electric energy exceeds the set value of a maximum load electric energy. CONSTITUTION:A maximum electric power setter 17 sets the maximum value of electric power to be managed by subtracting the power consumption of power load facilities 251..., 25n, the power consumption of which is fixed, from the maximum contract demand. A subtractor 16 calculates the voltage difference between the setter 17 and an adder 15. A subtractor 18 inputs a voltage set by an inverter power setter 19 in addition to the output of the subtractor 16 and calculates a command value for operating an inverter 7. An inverter control output circuit 20 converts the calculated results of the subtractor 18 into signals for controlling the inverter 7 and controls the inverter 7 by outputting the signals. Therefore, when the subtractor 16 outputs, the operation of a high frequency induction furnace 8 which is driven by means of the output of the inverter 7 is reduced.

Title: Manufacture of semiconductor device
Inventor: KAMIYAMA SHINYA
IPC: G03F7/00
Filed: 1990-10-15
Abstract: PURPOSE:To evade the transfer of defects of original plates by performing multiple exposure by using >=2 original plates for the formation of one image. CONSTITUTION:A 1st original plate (having a defect or Cr absence) is used to perform exposure by nearly a half as much as the exposure quantity required for image formation on photoresist 4 on a semiconductor substrate 6 coated with the photoresist 4 and another original plate is used to perform exposure by nearly a half as much as the exposure quantity required for the image formation. Consequently, the transfer of white absence such as Cr absence is prevented. Then the semiconductor device 6 which is exposed by using the latter original plate is further exposed. Therefore, the transfer of a black defect due to dirt and dust can be precluded. Consequently, even when an original plate on which whether or not there is a defect can not be found is used, a resist image which is originally required can be formed.

Filed: 1986-11-19
Abstract: PURPOSE:To supply the same amount of toner as consumed toner in a developer to a containing part from a hopper and to keep the toner density in the developer roughly constant by previously containing the developer and toner in an unused developing device. CONSTITUTION:When 1st-3rd sheets 28, 30 and 38 are removed from the developing device, the toner 32 enters through an auxiliary opening hole to prepare a auxiliary developer with a content ratio higher than a main developer 24. A space occurs in a main containing part 44 because the toner in the main developer 24 is consumed, and the auxiliary developer goes into the main containing part 44 through a main opening hole 42 on a partition 40. Agitating actions 54 and 56 agitate and mix the fed auxiliary developer with the main developer 24 to raise the toner density, and the initial state of the main developer 24 is restored. Since the auxiliary developer is a mixture of the main developer and toner and has magnetism, it is attracted by the magnetic field generation means of a sleeve 12, whereby a quick toner supply and the restoration of the density of the toner in the developer are attainable.

Abstract: PURPOSE:To foresee the degree of under- and over-exposure at each section of an object at the time of automatic exposure control, by displaying the difference between an exposure value for control obtained with a prescribed argorithm from plural photometric values and an exposure value obtained from the plural photometric values. CONSTITUTION:A controlling exposure value is determined by performing prescribed argorithm calculation on the photometric value of each section obtained by performing partial photometrical measurement to plural sections of an object by means of partical photometrical means 1-3. An operation means 8 calculates differences between exposure values corresponding to each partical photometric value obtained by means of the means 1-3 and the controlling exposure value. An indicator 21 displays display marks indicating the difference calculated by the means 8. Therefore, the degree of under- and over-exposure at each section of the object, to which spot photometrical measurement is performed, can be foreseen even at the time of automatic exposure control.
