Title: Camera
Inventor: MAENO HITOSHI
IPC: G03B15/05
Filed: 1995-05-15
Abstract: PURPOSE: To detect artificial light by serving also as a remote control receiving circuit in order to suppress cost-up and to prevent a mounting space from being increased. CONSTITUTION: The light of a remote control signal for controlling the action of a camera 2 from the outside is received by a remote control signal receiving circuit 4 incorporating a band-pass filter 3 from a remote control transmitter 1. Besides, the camera 2 is set to the receiving mode of the light of the remote control signal by a remote control receiving mode set part 6. According to the waveform of the signal outputted from the receiving circuit 4, the existence of the remote control signal is decided by a remote control signal decision part 7 and the existence of the artifical light whose frequency is different from the remote control signal is decided by an artifical light decision part 8. Then, the filter 3 is controlled by a control part 5 based on the outputs of the set part 6 and the decision part 7.

Title: Method and device for manufacturing optical master disk
Inventor: MORIMOTO AKIO
IPC: G11B7/0045
Filed: 1988-05-12
Abstract: PURPOSE:To form a resist pattern in which an exposed pattern with almost the same width can be generated and to improve the equality of a pre-format signal by setting the power of a laser beam to expose a sector mark bit less than the power to expose another bit. CONSTITUTION:A pre-format signal generation circuit 7 generates the pre-format signal (a), and outputs it to a sector mark signal separation circuit 8 and a pulse synthesis circuit 11. The circuit 8 separates a sector mark signal (b) from the signal (a), and modulates the signal (b) by a pulse signal (c) with a prescribed frequency from a pulse generation circuit 9 via a pulse synthesis circuit 10, then, sets it as a pulse signal (d). Next, the signals (a) and (d) are synthesized at the circuit 11, and an optical modulation element 12 is driven. Since the relative light quantity of the element 12 is reduced corresponding to a driving frequency, the exposure power light 1 of a sector mark bit part is reduced compared with another exposure power light 2. Therefore, the pattern width of the sector mark part can be prevented from being widened, and the quality of the pre-format signal can be improved.

Title: Liquid-phase epitaxially-growing apparatus for oxide single crystal thin film
Inventor: HIBIYA TAKETOSHI
IPC: H01B3/02
Filed: 1979-09-11
Abstract: PURPOSE: To make film thickness uniform and enable mass production of thin films by holding substrates at fixed positions in a melt with a position detector detecting communication between a substrate supporting jig and the melt and a means determining the crucible-substrate position on the basis of detected positions.  
     CONSTITUTION: When substrate supporting platinum jig 2 is lowered with raising or lowering motor 8 until the jig tip contacts with melt 7 for epitaxially growing single crystal thin films, a position detector acts to detect the set position and transfers it to timing relay 10. Relay 10 stops motor 8 on the basis of the signal. Thus, substrates 11, 12 are automatically held at optimum positions in melt 7. After the passage of a preset fixed time the substrates are pulled up from melt 7 with motor 8.

IPC: H01L29/74
Filed: 1992-05-11
Abstract: PURPOSE:To obtain a power switching element high in breakdown strength and low in ON-state voltage by a method wherein an opening is provided to the drain region of a MOSFET, and a gate electrode connected to the gate electrode of the MOSFET is installed on the opening concerned. CONSTITUTION:An opening 12 is provided at the center of an N<+> drain region 6 to enable the surface of an N base layer to be exposed. A gate electrode 13 is provided onto the surface of the N base layer exposed at the opening 12 through the intermediary of a gate insulating film. The gate electrode 13 is connected to a gate terminal G together with the gate electrode 8 of a MOSFET. When a positive voltage is applied to a collector terminal C, a potential difference is produced between the collector terminal C and the gate electrode 13, so that depletion layer is made to spread from the N base layer of the opening 12 just under the gate electrode 13 and joined together with a depletion layer which spreads from a PN junction between the N base layer 3 and the P base region 4 to form a depletion layer 11 which spreads uniformly. Therefore the drain region 6 is restrained from increasing in potential, so that a semiconductor device of this design can be enhance in breakdown strength without increasing the P base region 4 in depth.

Title: Buffer circuit
Inventor: HONMA NORIYUKI
IPC: H03K19/08
Filed: 1982-07-07
Abstract: PURPOSE:To obtain a circuit of high speed and low power consumption by combining bipolar and CMOS transistors(TRs) to constitute a noninverting type composite buffer circuit. CONSTITUTION:N-channel MOSTRs QM1, QM2, P-channel MOSTRs QM2, QM3 and NPN bipolar TRs QB1, QB2 are provided. When both inputs and outputs are at high potential, the TR sQM2, QM3 are turned off and the TRs QM1, QM2 are turned on. Thus, the TRQB2 turns off and a load of an output OUT is capacitive, then the TRQM1 turns off. When the output OUT goes to a low potential, since no base current is applied from the output OUT to the TRQB2, the TRQB2 turns off and no current flows to the TRQB1. As far as the input/ output remains at high or low potentials, only the leakage current flows and the power consumption is almost zero.

Abstract: PURPOSE:To improve the correcting accuracy of focusing characteristic corresponding to miniaturization of a pattern and an increase in an exposure region by providing illuminance distribution measuring means, focusing characteristic calculating means and focusing characteristic correcting means. CONSTITUTION:An image face on a wafer W of reticle R is divided to obtain illuminance distribution of each part (10A).

A controller 10 obtains information of an illuminance sensor 11, a shutter control unit 2B, a blind 6A, a pressure regulator 12 based on the results to correct the focusing characteristic. Variation in the focusing characteristic when a projecting optical system with intensity distribution of the illuminated light does not uniformly absorb the light is calculated as the distribution of temperature rise in a lens face to predict the variation. The lens face is divided corresponding to the divided image face, the light absorption and the exchange of the heat are calculated, and the temperature rise of the part is obtained. When parameters are regulated to match the actual focusing characteristic change, the distribution of the focusing characteristic change in the image face can be predicted to improve the focusing characteristic.
