Title: Lithography device for wafer
Inventor: SAGAWA KOICHI
IPC: H01L21/677
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To prevent the change in exposure condition as time passes by determining the exposure condition for wafer when the test result of registration accuracy of wafer pattern is within an allowable range, by removing a resist of a wafer when it is out thereof, and by repeating steps from resist coating to pattern registration accuracy testing. SOLUTION: A controller 18 controls the transfer of wafer by means of a robot arm 16 and applies a resist to a wafer in a resist coating unit 4. The wafer coated with a resist is exposed and developed one by one by an exposure unit 6 and a developing unit 8 respectively, and the registration accuracy is tested by a registration measuring unit 10. When the test result is within an allowable range, the exposure condition for wafer is determined, and when it is out thereof, a resist is removed from the wafer by a resist removing unit 12, and then steps from resist coating to pattern registration accuracy testing are repeated.

Title: Transmitting circuit
Inventor: HARAO ATSUSHI
IPC: H04B1/16
Filed: 1981-06-30
Abstract: PURPOSE:To reduce the power consumption of a transmitting circuit, by breaking a power supply to an amplifier with a demodulated burst signal. CONSTITUTION:The carrier wave sent from a terminal 1 is amplified by an amplifier 2 and then applied to a modulator 3. A burstlike modulated signal is applied to the amplifier 3 through a terminal 4, and as a result, a desired modulated wave is obtained at a terminal 5. While a switching circuit 10 is provided between a power supply part 6 and the amplifier 2. The circuit 10 is turned on only when the burstlike modulated pulse signal applied from the terminal 4 exists, and turned off in other modes. Thus no power is supplied to the amplifier 2 when the circuit 10 is turned off. This contributes to a reduction of the power consumption of a transmitting circuit.

Title: Metal composite oscillation-damping steel plate with high welding properties and its manufacture
Inventor: ISHII YOSHIO
IPC: B32B15/01
Filed: 1990-04-20
Abstract: PURPOSE:To improve ease of welding by providing zinc particles coagulated from a semi-molten state between steel plates or plated steel plates as an intermediate layer, and dispersing stainless steel particles in said intermediate layer at a specific volume rate. CONSTITUTION:A metal composite oscillation damping stainless steel consists of zinc particles 4 coagulated from a semi-molten state provided between plated stainless steels 1, 2 as an intermediate layer 3. The intermediate layer 3 contains electroconductive stainless steel particles 5. Electroconductivity between the plated stainless steels 1, 2 is enhanced by allowing the presence of the particles 5. Subsequently, a large amount of electric current is required and a proper current range is widened. Thus metal vapor generation is also eliminated, resulting in ease of welding. In addition, voids are formed between the stainless steel particles 5 and therefore, oscillation can be damped significantly. In this case, the volume rate of stainless steel content is 10% or higher and 70% or lower.

Title: Optical modulation device for subcarrier transmission system
Inventor: KAWAMURA HIROSHI
IPC: H04B10/588
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To provide the optical modulation device for the subcarrier transmission system which can transmit a light signal with higher efficiency than before. SOLUTION: Of the optical modulation device for the subcarrier transmission system, an optical phase modulator 7 imposes optical phase modulation on an inputted light signal with a specific phase modulation index according to an inputted electric signal and outputs the modulated signal.

     CONSTITUTION: A lower end of a sub-frame 6 for a front loader 1 is located at higher position than heights of front wheels 11 when the front loader is detached from a tractor 9, because a stand 16 is deflected backwardly. Consequently, a chassis 10 may be forwarded easily between a pair of lift arms 2 and an engaging member 23 deflects the stand 16 forwardly. By this action, the rear end 2b of the lift arm 2 is lowered, therefore, engaging holes 13, 14 for the sub-frame 6 and a main frame 12 respectively may be coincided and engaged with pins. When the front loader is desired to be removed, the pins are removed and a finger of the engaging member 23 is engaged with the stand by adjusting with a wheel attached, thereafter, the chassis is moved backwardly, thereby, the stand is deflected backwardly.

IPC: H04L1/00
Filed: 1992-04-23
Abstract: PURPOSE:To perform the appropriate demodulation of signals at a demodulator by flattening out spectrums of signals outputted after bit interleaving processing at a modulator. CONSTITUTION:A modulator 51 outputs modulated signals after inserting auxiliary signals S supplied from the outside to the overhead parts of plural data frames inputted in parallel from the outside, performing the bit interleaving processing, and further by performing the modulation with a prescribed frequency carrier. The modulated signal is demodulated at a demodulator, and the plural numbers of data inputted to the modulator 51 is obtained. When the auxiliary signals S are supplied, the auxiliary signals S are outputted to the modulator 51. When the auxiliary signals S are interrupted, the detection of the interruption is performed, and an auxiliary signal generating means 41 to output the arbitrarily varying signals to the modulator 51 at the time of this interruption detection is connected to the modulator 51. Thus, even when the auxiliary signals S are interrupted, the substituted signals are inserted to the overhead parts, so that the spectrums of the modulated signals outputted from the modulator 51 are flattened.

Filed: 1987-04-27
Abstract: PURPOSE:To prevent an impurity from being diffused to the outside during a heat-treatment process or an oxidation process by a method wherein, prior to a process to remove an oxide film, polycrystalline silicon is applied to both faces of a P/P<+> type silicon substrate and the oxide film is wet-etched. CONSTITUTION:An N-type well 3 is formed by using a P/P<+> type silicon substrate; polycrystalline silicon 5a, 5b with 1000-3000 Angstrom  are applied to insulating films on both faces of the substrate by a low-pressure CVD method. Then, the polycrystalline silicon 5a is removed by using a parallel-plate type dry etcher. During this process, the P/P<+> type silicon substrate is placed on a target with only its surface exposed to a plasma. An etchant cannot creep to the rear. Accordingly, the polycrystalline silicon 5b on the rear is not removed and only the surface is etched. Then, only an oxide film 4a on the surface is removed by using a mixed solution of hydrofluoric acid and ammonium fluoride. Because an oxide film 4b on the rear is covered with the polycrystalline silicon 5b, it is not removed.

CONSTITUTION:When water 2 is introduced into a container 1, and water heating operation is started, a boiling lamp 10 is turned ON, and a boiling heater 25 is turned ON, and the water 2 in the container 1 is heated, and temperature rises. The water in the container 1 is boiled, and the hot water having a proper state is formed and the temperature is kept. In this state, a boiling flag is turned OFF, and since a hot water temperature sensor 3 detects the proper temperature state of the hot water, an electric motor device 4 is operated when a hot water supply switch 9 is operated, and the hot water having a proper temperature is supplied. When the quantity of the hot water 2 in the container 1 reduces through use, and the supplement of water is required, the how water temperature lowers. When the hot water temperature lowers outside a proper temperature range, the operation of the motor- driven device 4 is prohibited, even if the hot water supply switch 9 is operated, since the hot water temperature sensor 3 detects the state, and the supply of the hot water in the container is prevented.
