Title: Receiver for pulse radar
Inventor: TORITSUKA HIDEKI
IPC: G01S7/285
Filed: 1992-06-23
Abstract: PURPOSE:To reduce an amount of change in oscillation frequency due to a drawing effect to easily set an intermediate frequency signal within an operation frequency band by adding a second harmonic of a local oscillator signal to a mixer with a relation of a half difference between frequency and intermediate frequency of a high frequency pulse signal. CONSTITUTION:An output of a second harmonic (frequency 2Fl) is taken out from an oscillation signal generated by a local oscillator from a connection point 39 of an open stub 34 having 1/2 wavelength and an open stub 38 having 1/4 wavelength via a capacitor 40, amplified 41 and added from a terminal 42 to a mixer as a local oscillation signal. Frequency Fl of the oscillation signal generated by the local oscillator has relation of Fl=(Fr+ or -Fi)/2 where frequency of a high frequency pulse signal is Fr and intermediate frequency is Fi. Therefore the frequency Fl largely separates from the frequency Fr, so that even if an excessive high frequency pulse signal is input to the local oscillator as leakage power, a drawing effect of the local oscillation signal can be suppressed.

Inventor: MIURA KONOE
IPC: H01L21/30
Filed: 1985-07-24
Abstract: PURPOSE:To prevent generation of pin-holes by processing the surface of wafer previously with the dilution of sensitive solution in case of forming a photosensitive layer by coating wafer with water soluble sensitive solution including natural protein. CONSTITUTION:The water soluble sensitive solution to coat a silicon wafer, a wafer or glass wafer having a thin film mainly consisting of silicon oxide or nitride of it at the surface contains the natural protein and is used by dissolving it into wafer with a heavy metal salt such as dichromate or diazo resin, etc. The wafer is coated with the dilution obtained by diluting such sensitive solution with water into 10 to 1,000 times. Thereafter, the wafer is dried in order to vaporize a part of the solvent (water) of the diluted liquid. After such processing with the diluted liquid, the wafer is coated with sensitive solution. Thereby, fitting of wafer with sensitive solution is improved and a film having no pin holes with uniform thickness may be obtained.

Filed: 1991-06-08
Abstract: PURPOSE:To effectively prevent sleeping drive by fixing a driver's seat on a seat support/reception portion provided on a floor surface via a vibration-proof material, fixing a vibration motor under this seat, and causing vibration of the seat. CONSTITUTION:A vibration motor 6 has a rotating shaft 6a to which an unbalancing weight 7 is fixed and this vibration motor 6 itself serves as a vibration source. The vibration motor 6 is electrically connected, via an inverter, to a battery 31 provided at a front body portion of an automobile 30. The electricity supplied to the vibration motor 6 is converted to an alternating current by the inverter. In cases where a driver becomes somewhat sleepy, he pushes a switch disposed on a control panel 32 to cause the vibration motor 6 to be turned on. Consequently, the vibration motor 6 is driven and vibrates by serving of this vibration motor itself as a vibration source. This vibration is transmitted to a seat 1 via a support plate 8 and a mounting plate 5. Accordingly, the driver seating himself in this seat 1 is restored from his sleepy condition by the vibration thereof, thus being freed from a sleeping drive.

Patent JP-H1014248-A (JP)
Title: Power supply
Inventor: SATO KATSUMI
IPC: H02M7/537
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To enhance the total efficiency by controlling a first switching element to be turned off at the time of abnormal load by turning a third switching element on, thereby lessening the stress applied to the switching element at the time of the abnormal load. SOLUTION: When an abnormality detection circuit 2 detects abnormality of a load Z1, a control circuit 3 stops driving a second switching element Q2 and turns on a third switching element Q3 at the same time. Consequently, a diode D4 is turned on. Since the gate terminal voltage of a first switching element Q1 goes to substantially 0V through a diode D5, the first switching element Q1 can be turned off, along with the second switching element Q2 when the abnormality detection circuit 2 detects an abnormality of the load Z1. Consequently, the stress applied to the first switching element Q1 can be lessened, when the load Z1 is abnormal.

Title: Dielectric electrode for discharge
Inventor: KAJIWARA TOSHIRO
IPC: H01J11/34
Filed: 1988-07-01
Abstract: PURPOSE:To aim at stabilizing electron discharge rate and the longevity of electrode by providing a protective dielectric layer at the thin part of the periphery of the dielectric layer formed on a metal conductor in order not to lower the insulating pressure of the part. CONSTITUTION:A discharge container 1 of a transmittant material, a fluorescent body 2, discharge gas 3, a secondary electron discharge material 4 and a dielectric layer 6 formed at a metal conductor 7 for smoothing electron discharge are provided. A protective dielectric layer 5 formed on the layer 6 for strengthening the periphery thinner than the other parts of the dielectric layer 6 and a metal conductor 7 are further provided. In this case, as the electric field is centralized on the electrode peripheral part, if the breakdown is generated in the peripheral part of the dielectric layer, the metal conductor 7 is directly subjected to the ion shock and sputter etched so as to lose original secondary electron discharge function. However, after forming the dielectric layer 6, the peripheral part of the dielectric body is coated with the dielectric body for reinforcing the thin part of the dielectric peripheral part so as to form a protective dielectric layer 5. The longevity of the electrode as well as the stable secondary electron discharge characteristic can be thus obtained.

Abstract: PURPOSE:To obtain a still picture telephone system with short picture transmission time by adding a high speed MODEM section and a high efficient coding section to a still picture telephone system. CONSTITUTION:In the case of sending a digital video signal stored in a display memory 7a to an opposite terminal equipment, when the opposite terminal equipment has a communication capability of a color picture, a coding means 13 applies high efficient coding, a high speed MODEM 12 modulates the signal and sends the result to a telephone line.

In the opposite terminal equipment, a video signal is demodulated by the high speed MO DEM or the AM-PM MODEM in response to the communication capability and the result is written in the display memory 7a. Thus, in case of terminal equipments having the communication capability of the color picture, the transmission time is reduced and if any terminal equipment has communication capability of a color picture, a white/black still picture is sent.
