IPC: H01L31/18
Filed: 1982-01-27
Abstract: PURPOSE:To prevent an adverse effect generated in case of heat treatment effectively by previously laminating a heat-resisting insulating thin-film onto a photoelectric transducing film laminated onto a substrate and activating and thermally treating the photoelectric transducing film. CONSTITUTION:The photoelectric transducing film 2 requiring activation through heat treatment is formed onto the insulating substrate 1. The heat-resisting insulating thin-film 3 is laminated so as to coat the whole surface of the upper section of the film 2. The film 2 is activated and thermally treated. The film 3 is patterned in desired form, and an electrode thin-film 4 is formed. Accordingly, the generation of a lattice defect due to the evaporation of elements in the photoelectric trausducing film in case of heat treatment and the lowering of photoelectric transducing characteristics, such as the degradation of sensitivity, the variance of characteristics, etc. resulting from the adsorption of impurities existing in an atmosphere can be prevented effectively.

IPC: E21D20/00
Filed: 1990-01-19
Abstract: PURPOSE: To perform a boring and raise a rod rapidly and economically by fixedly and holdably inserting an inner rod and a tie rod before raising an outer rod and, in that state, raising the outer rod. CONSTITUTION: Using power rotating heads 25 and 26 movable on a boring mount 6, boring is performed by a double rod comprising an inner rod 9 and an outer rod 10 and the double rod is raised.

Title: Electronic editing device of vtr
Inventor: KANASHIKI MASAAKI
IPC: G11B27/029
Filed: 1983-01-26
Abstract: PURPOSE:To insert a picture to a desired position accurately at all times by inserting and recording a new picture signal while leaving horizontal and vertical synchronizing signals recorded in advance on a tape recorded already as they are. CONSTITUTION:When the tape 1 after recording is reproduced and the tape comes to a desired position of insertion while monitoring the tape by a monitor 11, an inserting command is given to a recording/reproducing changeover timing circuit 8 and then recording/reproducing changeover switches 3a, 3b, 4a, 4b are switched to the recording terminal P. A timing signal generated from the changeover timing circuit 8 is generated only at the video signal period of a reproduced video signal (Fig. a) as shown in Fig. (b) and does not appear at the synchronizing signal period. Thus, when the insertion command is given to a device in the normal reproducing mode, the changeover timing signal is transmitted from the timing circuit 8 only during the period given by the command afterward and the recording mode is obtained.

Title: Driving method for ferroelectric liquid crystal panel
Inventor: HAMANO YASUKAZU
IPC: G02F1/133
Filed: 1990-01-23
Abstract: PURPOSE:To eliminate the inconvenience arising at the time of resetting and to allow the driving of a one-field writing system with high display quality by putting all of the picture elements selected in the phase of the first half into a 1st stable state, then executing the holding of the 1st stable state and the inversion to the 2nd stable state by the 2nd half. CONSTITUTION:All of the pulses of the first half exceed the threshold at 7V0 at the time of a bright state and at 5V0 at the time of a dark state and, therefore, the picture elements are reset in the dark state. The pulses of the second half exceed the threshold at -5V0 at the time of the bright state and, therefore, invert from the dark state to the bright state. These pulses do not attain the threshold at -3V0 and, therefore, maintain the dark state at the time of the dark state. On the other hand, + or -V0 voltage is attained and the inversion of the state is not executed in either case, the bright state and the dark state, when scanning electrodes are not selected. The deterioration in display quality by the flickering at the time of resetting is eliminated and the writing of the display data of one screen is executed in one field with high quality.

Abstract: PROBLEM TO BE SOLVED: To facilitate the control over a broad band with a small sized device by controlling respective amplifier characteristics of two amplitude variable means while keeping an optional correlation so as to suppress amplitude fluctuation without distorting even a high output signal. SOLUTION: After a distributed output signal is controlled to have a desired amplitude by amplitude variable means 10, 12, the result is fed to input terminals 7, 9 of a power synthesis means (in-phase) 8, in which the signals are synthesized in phase and the result is outputted to an output terminal 4. Let an input signal be cosα, the signals fed to the input terminals 7, 9 of the power synthesis means (in-phase) 8 are respectively Bcosα and A cosα. The amplitudes A, B in the amplitude variable means 10, 12 are optionally controlled by a control means 14. In the case of controlling the amplitudes A, B as (A<2> +B<2> )<1/2> =const., only the phase is made variable while keeping the constant amplitude. In the case of controlling the amplitudes A, B such as B/A=const., only the amplitude characteristic is controlled so as to keep the phase constant.

Title: Heat recovery in urea synthesis
Inventor: INOUE SHIGERU
IPC: C07C239/00
Filed: 1980-02-05
Abstract: PURPOSE: To utilize the waste heat, effectively, in the urea synthesis from NH 3 , and CO 2  by solution recycling process, by recycling the heat generated in the partial condensation stage after the high-pressure separation stage, the low-pressure separation stage and the concentration stage, to the concentration stage by means of heat exchange.  
     CONSTITUTION: The urea-containing liquid obtained by the reaction of NH 3  and CO 2  is passes successively through the high-pressure separation stage and the low- pressure separation stage to decompose and separate the unreacted ammonium carbamate (unreacted A). The aqeuous solution of urea (still containing a small amount of unreacted A) is passed through the concentration stage to decompose and separate the remaining unreacted A, and at the same time, to evaporate water. The separated mixed gas composed of NH 3 , CO 2  and water is condensed and recycled to the urea synthesis stage. In the above-mentioned urea synthesis, the heat generated by the condensation of the mixed gas is removed by the indirect heat exchange with the urea solution of the concentration stage, and the solution is recycled to the concentration stage, thereby recovering and reusing the heat of condensation.

Title: Plasma etching device
Inventor: TANAKA TAKEO
IPC: H01L21/302
Filed: 1995-01-30
Abstract: PURPOSE: To avoid the occurrence of defective etching due to overheating of a wafer and thereby to perform proper etching with constant stability by letting reasonable amount of gaseous He for cooling flow between a lower electrode and the wafer thereon in a plasma etching device. CONSTITUTION: The wafer 1 on the lower electrode 3 is subjected to an etching treatment by impressing high-frequency voltage between an upper electrode 2 and the lower electrode 3 in a chamber 6 and generating plasma 4 between both electrodes 2, 3. The wafer 1 and the lower electrode 3 are attracted to each other by energizing from an ESC power source 8 to improve mutually thermal conductivity and the wafer 1 is cooled by letting gaseous He flow from an introducing line 11 to a space between the wafer 1 and the lower electrode 3. When a resist on the wafer 1 is denatured because of large high-frequency voltage, pressure of gaseous He between the wafer 1 and the lower electrode 3 is compared with the pressure set in a pressure discriminating apparatus, and further, leakage of gaseous He is detected by a sensor 5.  When defective cooling by gaseous He is generated, impressing of the high-frequency voltage is interrupted by an off-switch 9. Thus, defective etching on the wafer 1 is prevented from occurring.
