Title: X-ray topography
Inventor: MATSUI JIYUNJI
IPC: G03B42/02
Filed: 1982-03-23
Abstract: PURPOSE:To record a crystal grain boundary, a lattice defect, a deposit and variation of a lattice constant etc. in a single crystal in high resolving power, by using a high polymer resist as a photosensitive agent for X-rays. CONSTITUTION:An X-ray flux 1 having 1mm. width is irradiated to a single crystal 2 to be inspected through a slit at a point 300mm. apart from an X-ray source of a CuK1 ray and a diffraction pattern is photographed by using a high polymer resist 7 sensible to X-rays. The photographed resist is treated with a developer after post-baking (110 deg.C, 30min) and the figure of a lattice defect is patterned. Hereafter, the resist 7 is masked and a part of a silicon oxidized film 6 is removed by buffer fluoric acid. Therefore, the figure of the lattice defect is formed on a silicon substrate 5 as the pattern consisting of the film 6 by removing the resist 7 used as the mask.

IPC: G11B5/70
Filed: 1992-01-31
Abstract: PURPOSE:To achieve a good electromagnetic conversion characteristic by a method wherein the title medium is provided with a magnetic recording layer having a specific thickness and the total thickness of a nonmagnetic support body and the magnetic recording layer is set to a specific thickness or higher. CONSTITUTION:In a magnetic recording medium, the thickness of a magnetic recording layer 2 is set at 2.5mum or higher and the total thickness of a nonmagnetic support body 1 and the layer 2 is set at 9mum or lower.

Title: Formation of sol-gel thin film
Inventor: AKAMATSU YOSHINORI
IPC: C03C17/25
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a film forming method which continuously form a uniform optical thin film of about>=2μm and more particularly about >=1μm on a large- area substrate using a sol-gel liguid by a spin coating method. SOLUTION: A coating liquid for forming a thin film is dropped onto the surface of a substrate which is set on a spin coater and is under rotation in the film forming method which forms the sol-gel thin film by the spin coating method on the substrate. After the film is formed on the surface under spin rotation from the coating liquid, the spin rotation of the substrate is once stopped before the coating liquid formed as the film loses the flow property due to beginning of drying. The filmed coating liquid is leveled off by its own flow and the substrate is rotated at a low speed in the leveled-off state, by which the uniform film is formed.

Title: Setting device for preset voltage of frequency synthesizer
Inventor: MURAKAMI YUKIO
IPC: H03L7/18
Filed: 1981-03-31
Abstract: PURPOSE:To produce a conversion table with high efficinecy, by connecting an automaticvoltage control circuit to a PLL circuit of a frequency synthesizer. CONSTITUTION:First a P-ROM7 and a D/A converter 8 are separated from each other by a switch 11. When digital values D1-Dn, i.e., the channel information are supplied to a programable counter 6, the control voltage VC of a VCO5 varies by the function of a PLL circuit. The voltage VC is applied to the minus (-) input of a comparator 10 via a time constant circuit 9. The comparator 10 applies the voltage corresponding to the error between the voltage VC and the reference voltage VR to a preset input 52 via a switch 11. The voltage of the input 52 differs by the values D1-Dn. Accordingly, the voltage of the input 52 receives an A/D conversion through an A/D converter 12 every time the values D1-Dn have some difference and then writtn into the P-ROM packaged to a P-ROM writer 13. In this case, the values D1-Dn function as the address signals.

Abstract: PURPOSE:To relieve the operating rate of a control signal line between a radio base station and a radio transmission reception station and the processing load of the radio base station when reception state measurement control of a radio channel of a radio exchange system is implemented. CONSTITUTION:A radio base station 500 sends an averaging procedure (unit of averaging, number of times of averaging, calculation method of averaging) in an averaging procedure information memory 51 to each of radio transmission reception stations 300-302. Each of the radio transmission reception stations 300-302 uses a calculation section 32 to average the reception state measurement result of an outgoing radio channel of its own station and adjacent stations and the reception state measurement result of an incoming radio channel 200 reported from a mobile terminal equipment 100 for processing period, stores the averaged measurement result to a measurement result collection memory 33 and reports the result to a radio base station 500. The radio base station 500 uses a measurement result analysis section 52 to analyze the result of averaging measurement thereby implementing the optimization of incoming and outgoing radio channels and output control of the mobile terminal equipment 100 and the radio transmission reception stations 300-302.

Title: Liquid tube convection type combustion heating furnace
Inventor: KUBOTA NORIKAZU
IPC: F23C99/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce NOx in a waste gas by forming liquid tubes positioned on the side of a planar flame type burner using diameter-varied tubes with the ends of the tubes slenderly reduced to prevent a gap corrosion caused by an absorption liquid. SOLUTION: Liquid tubes composing a group of upstream side liquid tubes 56A reduced slenderly at the ends thereof to eliminate an uneven surface weld metal 61 otherwise caused by overlapping thereof even when the liquid tubes approach mutually. Hence, gap corrosion by an absorption liquid is hard to occur. The liquid tubes composing the group of the upstream side liquid tubes 56A can be erected being kept in contact with a side part of an internal wall facing a vertical side communication part or approaching it up to 2mm or less without overlapping the weld metal 61.  As a result, the liquid tubes arranged in the heating chamber 52 are further increased in the erection density so that a flame formed by the planar flame type burner quickly radiates heat to a diluted liquid through walls of a number of liquid tubes comprising diameter-varied tubes to lower the temperature thereof thereby reducing NOx contained in a waste gas.

Filed: 1988-02-29
Abstract: PURPOSE:To eliminate noise in an excellent way even if the mode of an input video signal is changed by switching automatically the feedback constant in response to the mode of the input video signal. CONSTITUTION:A mode detection circuit 8 detects whether an input video signal SIN is a reproduced output of a video tape recorder or a tuner output or the like, a detection signal SD is outputted as a 3-bit digital signal and supplied for 3-bit share in a 9-bit address signal of a ROM 6. A signal being a product between a noise component SN and a feedback constant K in response to each mode of the input video signal SIN. Thus, noise reduction in response to the mode of the input video signal SIN is applied automatically. Thus, even if the mode of the input video signal SIN is varied, noise rejection is applied in a satisfactory manner.

Title: Reticule
Inventor: UDAGAWA SATORU
IPC: G03F1/42
Filed: 1992-03-04
Abstract: PURPOSE:To prevent the generation of an alignment defect by changing the positions of target patterns for an aligner and the positions of target patterns for reticules of conventional specifications. CONSTITUTION:Body chips 2 are formed within the reticule 1 and the circumference of the body chips 2 is left as a scribing regions 3 for dicing. The target patterns 4 of the aligner for alignment with the body chips 2 at the time of photolithography are formed within the scribing regions 3. The positions of the respective target patterns 4 within the scribing regions 3 vary with the respective reticules 1 of (a) to (c) at the time of producing an LSI by using the reticules of the different patterns in the same photolithography stage. The positions of the target patterns within the reticules, such as the reticules of a improved version of the patterns different from the patterns of the conventional specifications and the target patterns within the reticules of the conventional specifications are exchanged. The alignment by the aligner is not possible even if exposing is going to be made by the wrong reticule at the time of exposing and, therefore, an error is prevented.
