Title: Plasma generating device for decoration
Inventor: HAMAMOTO KAZUTOSHI
IPC: H05H1/48
Filed: 1990-04-09
Abstract: PURPOSE:To generate a plasma looking like an aurora over a wide area of space effectively in a simple structure by applying an AC high voltage power supply between an anode in a vacuum glass container and a metallic bottom plate connected to an earthed cathode. CONSTITUTION:An anode 14 in a glass vacuum container 11 is connected to one side electrode of an AC voltage power supply 15, and a cathode 13 is connected to the other side electrode of the AC high voltage power supply 15 through a metallic bottom plate 12 and earthed. As a result, a discharge is carried out between the electrodes 14, 13 and the bottom plate 12, and the area to generate plasma is expanded. And, since a minute surface current flows on the inner wall of the container 11, and the glass is also made into a part of electrode, a plasma of a large visual excitement can be generated. Consequently, a plasma looking like an aurora can be generated effectively along a wide area of space in a simple structure.

Abstract: PROBLEM TO BE SOLVED: To attain excellent demodulation by eliminating the effect of inter-symbol interference(ISI) in the case that a delay time of a delay wave generated in a multi- path propagation line exceeds a guard interval period. SOLUTION: In the orthogonal frequency division multiplex(OFDM) demodulator, a variable delay section 3100 delays a correction complex signals output of an adaptive filter section 30 by a valid symbol period +α, a complex multiplier 3101 and a sum average arithmetic section 3102 apply correlation arithmetic operation after and before the delay, integration arithmetic sections 3103, 3104, square arithmetic sections 3105, 3106 and an adder section 3107 apply their respective operations to real and imaginary parts of the result to obtain a correlation square signal. Furthermore, by means of a tan<-1> arithmetic section 3110 a phase rotation angle θ is obtained from the result of the integration arithmetic operation. A peak detection/hold section 3108 holds the αand θ at a peak value of the correlation square signal.  According to the operations above, each estimate value of a delay time of a delay wave, an amplitude ratio of the delay wave to a desired wave, and a phase difference between the desired wave and the delay wave is found, and a filter coefficient generating section 3109 generates a filter coefficient from each estimate value and provides an output to an adaptive filter section 30.

Abstract: PURPOSE:To obtain an always stable output signal by applying an impulse control signal corresponding to a change in a storage time of a solid-state image pickup element to a gain control amplifier when the storage time is changed. CONSTITUTION:An output signal of a CCD 3 is extracted via a buffer 4 and a GC amplifier 5, a detection circuit 7 detects an amplitude level and an error component from a reference voltage level is extracted via a differential amplifier 8 and fed to a gain control terminal of the GC amplifier 5. Thus, an output controlled to be equal to a reference level from the amplifier 5 is obtained. For the control above, a time constant having several vertical periods of the video signal is set. A CPU 13 sets a diaphragm 2 via a drive circuit 15 by using a data by manual input 14 and an output of the amplifier 5 calculates the shutter speed bringing the output signal to a prescribed value by the CPU 13 via an A/D converter 16 and a driving circuit 17 controls the storage time of the CCD 3. Moreover, a prescribed value is sent from the CPU 13 at a point of time of a change in the shutter speed and the value is fed to a gain control terminal via a D/A converter and a differentiating circuit comprising a register 19 and a capacitor 20. Through the constitution above, an always stable output is obtained.

Filed: 1983-05-27
Abstract: PURPOSE:To make the data base file access high-speed by adopting setting of cache buffer area security reference and a cache buffer use mode in the disc cache system. CONSTITUTION:A user task 11 generates information by the access of a data base file 3 and issues a processing request to an operating system OS16.

The size of the printing lines in this case is preferably 0.05-0.5mm and the pitch of the printing line 0.1-10mm. After the unmasked parts are subjected to, for example, DC electrolytic etching, the resist is removed by an inorg. acid soln. or org. solvent. An aq. dispersion of fluoroplastic such as tetrafluoroethylene is coated on the Al surface from which the resist is removed and thereafter, the surface is baked. The resin coating is thus executed.
