Title: Electrode structure for surface acoustic wave element
Inventor: IWAMOTO OSAMU
IPC: H03H9/145
Filed: 1991-02-22
Abstract: PURPOSE:To reduce a resonance frequency change caused by the change of operations with the passage of time at a surface acoustic wave element by reducing the size of an electrode particle. CONSTITUTION:The surface acoustic wave element equipped with an comb- shaped electrode on a piezoelectric substrate 4 has multi-layered film structure alternately laminating comb-shaped electrodes and lattice-shaped reflector electrodes by plural metals 5-8 such as aluminium, chrome and copper or the like. For example, the surface acoustic wave element of 150MHz band has about 0.6 micron electrode thickness. When this is composed of single-layer aluminium, aluminium particles in the electrode are grown big, a crack or the like is generated from the grain boundary of particles by the vibration of surface waves in the case of operating the element, and the resonance frequency of the element is changed. Therefore, since the electrode has the laminated structure, the growing of electrode particles can be suppressed in the case of forming the electrode, and the particles of electrode materials are reduced. Further, the resonance frequency change caused by the operational change with the passage of time at the surface acoustic wave element can be reduced.

Title: Branching and distributing device for catv
Inventor: NISHIBORI ISAO
IPC: H04N7/16
Filed: 1986-02-13
Abstract: PURPOSE:To suppress a side band generated owing to the ON/OFF operation of an RF switch of each subscriber and to eliminate the adverse influence of a disturbing wave upon adjacent channels by generating a disturbing wave discretely and further suppressing the disturbing wave through a narrow-band filter. CONSTITUTION:A signal generated by an oscillator 20 is amplified by an amplifier 21 firstly and inputted to an RF switch 30. The ON/OFF timing of this RF switch is for the stabilization of operation and the switch turns on when a VCO 28 oscillates stably and turns off when the oscillation frequency varies. A continuous wave from a precedent oscillator 20 is converted into a discrete signal through the ON/OFF operation of this RF switch 30. In this example, the disturbing wave is outputted discretely, so the spread of the side bands of the outputs of RF switches 12-15 which superpose the disturbing signal on drop lines of respective subscribers is suppressed even when the RF switches are operated at a faster speed.

Title: Communication equipment
Inventor: TAKAGI HITOSHI
IPC: H04B1/40
Filed: 1995-02-17
Abstract: PURPOSE: To provide a communication equipment free from mutual interference between a carrier for transmission and a reproduced carrier by eliminating the need of a local oscillator for transmission in a slave station to prevent the occurrence of a beat signal between the carrier for transmission and the reproduced carrier. CONSTITUTION: In the slave station, a demodulator 10 to which a reception IF signal is inputted reproduces a carrier in a carrier reproducing circuit 11 and demodulates a data signal to output it to a terminal equipment 1 and sends the reproduced carrier to a modulator 2 as a carrier 14 for transmission. Since the modulator 2 uses the carrier 14 for transmission to modulate the transmission data signal from the terminal equipment 1 and outputs a transmission IF signal.  Since the communication equipment is constituted so as to use the reproduced carrier reproduced by the demodulator 10 as the carrier 14 for transmission in the modulator 2, the need of the local oscillator for transmission in the slave station is eliminated, and the local oscillation frequency for transmission in the slave station and the reproduced carrier frequency are completely synchronized with each other, and the beat signal is not generated by the frequency deviation because mutual interference is prevented, and the constitution of the slave station is simplified.

Title: Device and method for preventing image persistence of display device
Inventor: AKUNE HIROSHI
IPC: G09G3/28
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To make the degree of image persistence uniform while displaying a same still picture for a long time by converting the coordinates of a still picture employing a dot number unit, that provides no adverse effect in viewing, and converting the conversion into a self same conversion on plural cycles. SOLUTION: A picture 'AB' is displayed by dots which are arranged in lateral and longitudinal coordinates. These dots are set on many lateral and longitudinal coordinate axis lines 21 of a coordinate system. The system is moved to left and right/up and down directions and the dot locations, that are the display locations, are changed to up and down and left and right directions. The displayed character 'A' and 'B' prior to a movement are moved on the coordinate system by the amount of a movement being set to the up and down/left and right directions. The movement is relatively equivalent to a case that the coordinate system is fixed and the coordinates of a picture are converted. The conversion is a self same conversion on plural cycles. Thus, image persistence of a screen is prevented by moving the position of the displayed picture for every constant time.  By using the unit having a number of dots, that provide no adverse effect in viewing to move the picture for every constant time, the image persistence is prevented without changing the display contents.
