Filed: 1991-11-27
Abstract: PURPOSE:To record and reproduce a recording signal such as a video signal with the same magnetic head at all times even when plural magnetic headswith the same azimuth angles are provided in the device. CONSTITUTION:A switching section 5 controlling the changeover of a magnetic head, a frame pulse generating section 6 generating a frame pulse, and a cycle number adjustment section 4 setting a recording cycle number of a burst signal differently are used to add a burst signal whose cycle number is different to a signal recorded by magnetic heads L1 and L2 (R1 and R2) of the same azimuth angle. At the reproduction, a burst signal section 10 and a cycle number detection section 11 detect the cycle number of the burst signal, and a 1st delay circuit 13, a 2nd delay circuit 14 and a drum motor control section 12 control a relative phase between a rotary drum D and a tape T (running system) based on the result of detection. Thus, a video signal or the like is recorded/ reproduced at all times by the same magnetic head.

Abstract: PURPOSE: To continuously record a series of information including voice for a long time by changing over a mode AV of simultaneously recording a video signal and a voice signal and a mode A of recording only the voice signal by a control signal and making them coexist with each other timewise. CONSTITUTION: A camcorder changes over the AV mode and the A mode respectively recording the video and the voice from a video camera 2 and a microphone 3 simultaneously and only the voice in a tape 4 by the control signal. A system controller(SC) 10 outputs the control signal adequately in accordance with the operation of an operation button and a recording part 5 makes the AV mode and the A mode coexist timewise according to the control signal. Moreover, the SC10 makes a video and voice AV and a voice V output by controlling a drum servo 8 and a capstan servo 9 and by controlling a reproducing part 7 at the time of a reproducing. Thus, this recorder can execute the recording for 10 to 20 hours when the mode is only the A mode and can effectively record a lecture, etc., for a long time when both modes coexist by using a tape for one hour when it is used in the AV mode.

Title: Method to make nitrogen oxide containing exhaust gas harmless
Inventor: UCHIDA SATOSHI
IPC: B01D53/56
Filed: 1992-12-21
Abstract: PURPOSE:To remove NOx from NOx containing exhaust gas highly efficiently with a small electric power by oxiding NOx-containing exhaust gas by plasma and adsorbing and removing the oxidized NOx with an adsorbent. CONSTITUTION:NOx-containing exhaust gas of a combustion furnace 1 is led to a plasma reaction container 5 through a dust removing apparatus 3. When voltage is applied between electrodes 110, 111 from an electric power source 6, plasma of the exhaust gas is generated between the electrodes 110, 111. The plasma excites and dissociates gas molecules of NOx to make them chemically active and thus the following chemical reactions; NO+O3 NO2 +Q2 and 2NO2+O3 N2O5+O2; are caused. The reaction formula shows that NO in the exhaust gas of the combustion furnace 1 which is led to the plasma reaction container 5 is oxidized and the oxidized NO2 and N2O5 are removed in an adsorbing tower 8. In this way, the method wherein NOx is once oxidized and the oxidized NOx is removed with an adsorbing agent can suppress the necessary electric power to about 1/10 as compared with a conventional NOx reducing method.

Title: Waver dicing method, radiation irradiation apparatus used for this method and adhesive sheet for wafer pasting
Inventor: KOGURE MASAO
IPC: C09J175/04
Filed: 1992-12-22
Abstract: PURPOSE:To easily obtain a desired chip interval in an expanding process by a method wherein the part of an adhesive layer on which a wafer has been pasted is irradiated with a radiation in a pattern shape and the part of the adhesive layer on which the wafer is not pasted is irradiated wholly with the radiation. CONSTITUTION:Since a part on which a wafer A is not pasted is irradiated wholly with a radiation, an adhesive layer 3 situated in the part progress in its hardening sufficiently. As a result, an expansion rate in an expanding process is lowered, and an excess expanding operation is made inessential. On the other hand, the adhesive layer 3 progresses in its hardening partially in a pattern shape in a part on which the wafer A is not pasted, but the adhesive layer 3 does not progress in its hardening sufficiently, and the expansion rate in the expanding process is not lowered so much. Consequently, when an adhesive sheet 1 for wafer pasting is expanded, the part on which the wafer has been pasted is expanded preferentially, and a sufficient chip interval can be obtained.

Title: Solar battery power generation module and device for diagnosing number of connected modules
Inventor: ISSHIKI MASAO
IPC: H02J7/35
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To enable legally unqualified workers to safely install a solar battery power generation panel. SOLUTION: A control circuit 51 diagnoses whether or not the output of an in-module power conversion circuit 50 is connected to a system interconnection inverter (8), and when the output is not connected to the inverter (8), suppresses the output voltage of the circuit 50 to a level for safety operator or lower. When the output is connected to the inverter (8), the circuit 51 sets the output voltage of the circuit 5 to a normal operating voltage. Consequently, the safety of workers can be secured, because no high voltage is impressed upon the output terminal of a solar battery module, until the module is actually fixed to a roof or another prescribed position and connected to the inverter (8) via a current collecting bus line 6. After the module is connected to the bus line 6, in addition, the module can automatically start its normal high- voltage outputting operations.

Title: Blood pressure monitor device
Inventor: REON
IPC: A61B5/022
Filed: 1991-11-29
Abstract: PURPOSE:To exactly judge a shock state by providing a means for detecting the blood flow start pressure at the point of the time when a pressure pulse wave is generated in the process for dropping the compressing pressure, a means for calculating the difference between the max. blood pressure value of a 1st blood pressure value and the blood flow start pressure and a correcting means for applying a pressure difference when a 2nd blood pressure value is smaller than a prescribed value. CONSTITUTION:The pressure is increased up to a target cuff pressure Pm when a start switch is turned on. The max. and min. blood pressure values (1st blood pressure values) are measured in the process of slowly dropping the pressure. The blood flow start pressure PS1 of the detection cuff pressure P of the pressure pulse wave of the 1st beat is detected and stored by a pulse wave sensor in the process of slowly dropping the pressure. The 1st blood pressure value is displayed by setting a rapid pressure releasing state. The pressure difference alphabetween the max. blood pressure value and the blood flow start pressure PS1 is calculated when the max. blood pressure value is in a prescribed range. The max. and min. blood pressure values of the 2nd blood pressure value are calculated in accordance with the max. and min. values of the 1st blood pressure value and the pressure pulse wave are calculated after the pulse wave sensor reads in one beat of the pressure pulse wave. The pressure difference alpha is added to the max. and min. blood pressure values of the 2nd blood pressure value to obtain the 2nd blood pressure value when the max. blood pressure value from the pulse wave sensor is lower than the predetermined value.

This ceramic fine hollow grains can be obtained by foam-generating ceramic composition material, for example, composed of 50-60% SiO2, 40-45% Al2O3, and 1.5-2.5% of others. Also, it is preferable that grain diameter is at a range of 5-350 μm. The grains of such a high compression strength are not broken against high stress and high shearing force in a composite process with aluminum, so as to form a light and dense compound material with about 1.06 specific gravity easily.
