Title: Pyrolytic boron nitride container and its manufacture
Inventor: KIMURA NOBORU
IPC: C23C16/34
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively manufacture a container which can stably be used by forming the structure of the container so as to have a distribution of the treansmissivity with respect to light (IR(infrared light)) of specified wavelengths, such that the transmissivity changes in the direction of height of the container, in a pyrolytic boron nitride(PBN) container used as a molecular beam source container for molecular beam epitaxy. SOLUTION: In this manufacture, the structure of the PBN container is formed so as to have a distribution of the transmissivity with respect to light of 2,600 to 6,500cm<-1> wave number, such that the IR-transmissivity changes in the direction of height of the container, that is, the transmssivity is stepwise and gradually reduced or increased in the direction from the bottom side toward the opening of the container. At this time, as the method for providing the container with this transmissivity distribution, any one of the following three methods can be used, namely: (1) changing the density of PBN to change the light absorption coefficient; (2) changing roughness of the outer surface of the PBN container to change the amount of scattered light; and (3) doping PBN with an element so as to change the thickness, area and dopant concn. of the doped layer.

Title: Apparatus for inspecting positioning accuracy of semiconductor wafer
Inventor: MARUYAMA SHIGERU
IPC: G03F9/00
Filed: 1986-10-09
Abstract: PURPOSE:To obtain a positioning inspection apparatus excellent in detection accuracy and sensitivity, by providing an optical system for converging light so that the light emitted from a light emitting element is not allowed to irradiate the outside of a linear Fresnel zone plate. CONSTITUTION:This inspection apparatus consists of a mirror 2 composed of a combination of a plane mirror 21 reflecting the light L emitted from a light emitting element 1 and an oval plane mirror 22 reflecting the reflected light from said mirror 21, and a light receiving element 5 detecting the reflected light from the mirror 22 being generated when the reflected light of a semiconductor wafer 7 is incident to said mirror 22. Further, an optical system 6 for converging the light L is provided so that the light L is not allowed to irradiate the outside of a linear Fresnel zone plate 3. By this mechanism, the light L is reflected by the mirror 21 to be condensed to irradiate the semiconductor wafer 7 having a mask of a diffraction lattice on the surface thereof and the reflected light from the wafer 7 is condensed using the mirror 22 to be detected by a detector 5 and the positioning state of the wafer 7 is inspected. At this time, since the irradiation of the outside of the plate 3 with the light L is prevented by the optical system 6 and a region B1 of low luminous intensity is not present, an S/N ratio is excellent, and detection accuracy and sensitivity are enhanced.

Title: Spotting scope and its focusing signal transmitter
Inventor: ONO TSUKANE
IPC: G02B7/04
Filed: 1993-08-31
Abstract: PURPOSE:To obtain a bright and clear magnified image by simplifying the focusing operation of the spotting scope even in an environment, such as at the freezing point. CONSTITUTION:An FM signal receiver 110 receives an FM signal of 27 or 40MHz (count value transmitted from the focusing signal transmitter) by a switch operation of selection switches 66, 68. A relational arithmetic unit 120 calculates a difference between the count value from the FM signal receiver 110 and the count value outputted from a counter 130 for signal reception and outputs the result thereof to a motor controller 140. A counter control circuit 150 which monitors forward/backward revolution signals updates the count value of the counter 130 for signal reception when the motor controller 140 outputs these signals to a motor 54 according to the difference which is the result of the calculation. An origin switch 60 is connected to the reset terminal of the counter 130 for signal reception. The perfect coincidence of the mechanical origin of the motor 54 and the count value '0' is thus obtd.

Title: Method of driving recording head
Inventor: KUWABARA NOBUYUKI
IPC: B41J2/36
Filed: 1988-09-28
Abstract: PURPOSE:To prevent heat accumulation in a recording head even when black continues by controlling conduction energy to a heating element so that specific relationship holds in conduction energy to the heating element at a time when all picture signals within a specified range represent heat-generating signals and conduction energy at a time when one of picture signals at an adjacent position represents a non-heat- generating signal. CONSTITUTION:Conduction energy is set so that the relationship of 1.7XE0<=E1<=5.0XE0 holds when conduction energy at a time when all dots within the range of detection are black to dots to be conducted is represented by E0 and conduction energy at a time when one of adjacent dots in the main scanning direction or the sub-scanning direction is white is represented by E1. It is because there is no difference in the calorific values of an edge section and a solid black section when energy E1 is made lower than 1.7XE0 and the solid black section is overheated and ink excessively permeates to a recording medium when a calorific value where the edge section is exposed distinctly is generated. In it because the difference of the calorific values of the edge section and the solid black section is increased when conduction energy E1 is made larger than 5.0XE0 and sufficient transfer is not enabled owing to insufficient energy in the solid black section when the calorific value where the edge section is exposed clearly is generated.

IPC: F27D1/18
Filed: 1990-09-12
Abstract: PURPOSE:To close a ceiling part of an arc type electrical furnace, assure an air-tightness in the furnace and reduce a concentration of oxygen in atmosphere in the furnace by a method wherein a gas seal member is disposed at a contact part between an upper end of the furnace and a lid of the furnace. CONSTITUTION:An annular flange 16 is projected out of an upper end outer circumference of a furnace 12, and a top surface of the furnace is defined by a top surface 16a of the flange 16 and a top end of a furnace shell 6. The first annular ring 20 and the second ring 22 are fixed in a concentric manner with the furnace body to the top surface of the furnace. An annular groove is formed there. The annular groove is provided with a blanket 18 of kaowool and then a gas seal member is constructed. Thus, as the furnace lid 2 is mounted on the furnace body 12, an inner flange 14a of a furnace lid frame 14 pushes against the blanket 18 and then the inner flange 14a of the furnace lid frame 14 is closely contacted with the blanket 18. Due to this fact, an air- tightness between the surrounding air and the atmosphere in the furnace is kept, so that it is possible to reduce a concentration of oxygen in the furnace and an amount of occurrence of nitrogen oxide.

Title: Memory circuit
Inventor: YAMAGUCHI TAKASHI
IPC: G11C11/419
Filed: 1985-10-28
Abstract: PURPOSE:To reduce the power consumption of a sense amplifier by accelerating a potential's fall of a data bus line when a memory circuit executes a read action. CONSTITUTION:At the time of the read action, a bit line B and the data bus line D begin to fall from a power source level VCC with the aid of information on a memory cell 11, and a difference voltage between a pair of data lines D and their inversions D are generated. In response to the generation, the sense amplifier 2 amplifies a bit line signal to output it to a pair of output lines OUT and their inversions OUT, thereby completing the read action. When the data bus line D falls to a logical threshold, an inverter 3 begins to invert an output N1, and the data bus line D is quickly discharged through Q16Q18. As a result, the gate voltage of a Q11 falls, and a current flowing to a GND through a Q13 speedily decreases, whereby the power consumption of the amplifier 2 is minimized.
Patent JP-S61142818-A (JP)
Title: Input and output circuit
Inventor: IGARASHI HATSUHIDE
IPC: H03K17/687
Filed: 1985-10-28
Abstract: PURPOSE:To prevent the dielectric breakdown due to the high voltage noise, etc. by connecting an input protecting impedance element between a junction of an output FET and an input/output terminal and the input terminal of an input FET. CONSTITUTION:An FETM12 is turned on when the relation between the source voltage V(A) of the FETM12 and the threshold value -VT is equal to -VD-(-V(A))-VT. Then the FETM12 is turned off with -VD-(-V(A))=-VT. Thus the voltage V(A) does not rise up any more even though the voltage higher than the source level is applied to the drain. That is, the V(A) is not set at >=-4V if -VD=-5V and VT=-1V, for example, are satisfied. Thus just -4V is applied to the gate of an FETM11 even in case the high voltage is applied to the drain of the FETM12 connected to an input/output terminal. As a result, the FETM11 never receives the dielectric breakdown. In case an output FETM13 has high breakdown strength between the drain and the source, a diode D1 which has the adverse breakdown with the voltage lower than said breakdown strength is connected to the FETM13 for protection of the FETM13.

Abstract: PURPOSE:To make insufficiency of density in black pixels compensable in a black line which follows a white line by a method wherein the number of black pixels in printing of a previous line is counted and, at the same time, printing pulse durations are controlled, based on a time from the moment of printing on the previous line to the moment of printing on a current line. CONSTITUTION:A black pixel counter 2-1 counts the number of black pixels in one line of printing. A timer 1-1 counts the time from the moment of printing on a previous line to the moment of printing on a current line. A latch circuit 2-2 latches the values counted by the black pixel counter 2-1 into said circuit. A latch circuit 3-1 latches pixel information and time information stored in a previous step into said circuit. A ROM 3-2 outputs printing pulse duration data, based on the pixel information and the time information. A printing pulse producing circuit 4-1 outputs '1' to Q1 until it reaches the printing pulse data. When the output to Q1 is finished, the outputs to Q2 through Q4 follow for generation of printing pulses which correspond to the number of black pixels in the printing on the previous line and the time from the moment of printing on the previous line to the moment of printing on the current line.
