Title: Residual side band elastic surface wave filter
Inventor: HIGUCHI YUUJI
IPC: H03H9/64
Filed: 1978-04-27
Abstract: PURPOSE:To omit the reception phase equalizer for the color TV broadcasting video unit by securing the delay characteristics which is defined by the radio facilities rule or the like. CONSTITUTION:For the residual side band elastic surface wave filter, the electric signals applied to input terminal 5 are converted into the elastic surface wave signals through input roller-screen type electrode 2. The elastic surface wave signals propagate on piezoelectric substrate 1 to reach multi-strip coupler 4, where the signal intensity of the direction vertical to the wave travelling direction is converted into the uniform elastic surface wave to reach output roller-screen type electrode 3 to be converted into the electric signals and then to be delivered 6. The frequency characteristics of coupler 4 is uniform, but the frequency characteristics of electrode 2 and 3 are not uniform but depend on the exciting intensity of the roller-screen type electrode, i.e., overlap a1 of the electrodes. Thus,,the roller-screen type electrode featuring the desired delay and amplitude characteristics can be obtained by giving the complex number equivalent to the necesary delay and amplitude characteristics in the form of the input of the Fourier reverse conversion. As a result, the reception phase equalizer can be omitted for the color TV transmitter.

Title: Strip line-waveguide converter
Inventor: SOGO HIROYUKI
IPC: H01P5/107
Filed: 1985-03-14
Abstract: PURPOSE:To decrease the overlapped part, to make small and to decrease the cost by using the copper pattern at the rear surface of the dielectric substrate as the earth pattern of the microstrip line and using it as the waveguide (WG). CONSTITUTION:To one edge of a strip line 26 formed by the copper foil at the surface of a dielectric substrate part 24, for example, a flow glass substrate 25, for example, one end of a gold plating copper foil ribbon 27 is soldered. Into a hole 29, for example, a hollow part 28-1 of an earth bush 28 made of a silver plated brass is inserted. Since the hollow part 28-1 and the probe part 31 form the coaxis the strip line mode is converted almost without damaging the coaxial mode. When the rear surface with the copper pattern of the dielectric substrate part 24 is tightly fixed to a case 23 with a screw 32 by covering the whole of the part of the removed H surface, a WG is formed and other edge of the probe 31 is protruded in the space of the WG. For this reason, the conversion of the alignment mode and the WG mode is executed almost without the loss, and after all, the strip line -WG conversion is efficiently executed. Thus, since the copper pattern at the rear surface of the dielectric substrate is used as part of the WG, the device goes to be small-sized and the cost is decreased.

     CONSTITUTION: If it is assumed that laser light 2 deviates like an optical axis 2b, the light deviates by quantity (a) in a light position detecting element 9 and by quantity (b) in a light position detecting element 10. Hence, the output corresponding to (a)W(b) is obtained in the output of a differential amplifier 15 and the  reflecting mirror 3 of a galvano type rotating element 4 is turned so that the laser  light 2 passes the optical axis 2c and assumes the optical axis parallel to the set  optical axis 2a. The deviation on the light position detecting element 9 of the optical axis 2a of this time becomes (a'). Hence, the output corresponding to (a') is  obtainable in the output of the differential amplifier 12 and the glass plate 5 of a  galvano type rotating element 6 is turned so that the optical axis 2c moves parallel  and passes the specified optical axis 2a.

In the case that the determination is YES, the starting of play is determined, and the operating state of the cart K is displayed on a display device 2.

Title: Solid-state image pickup device
Inventor: OOBA SHINYA
IPC: H04N5/335
Filed: 1982-03-31
Abstract: PURPOSE:To reduce fixed pattern noises and thus obtain a high sensibility by a method wherein an inversion circuit is provided between each vertical signal line and the gate of a transfer transistor, in a bi-dimensional solid-state image pickup element. CONSTITUTION:The inversion circuit 50 wherein the potential of each vertical signal line 4 is decided as one side input and the other side is connected to a common power source line 51 is provided to each vertical signal line, and thus the output is given to the gate of the transfer FET5. By the addition of the inversion circuit 50 of gain G, the transfer loss of charges is remarkably reduced to 1/(1+G)<2> resulting in the improvement of transfer efficiency, but, when the characteristics of the inversion circuit disperse, the conductances of the transfer FET disperse, and the amount of charges read out within a restricted transfer time differs, accordingly large fixed pattern noises are generated. After bias charges are injected from a CTD (e.g. BCD) 8 into the signal lines 4 through FETs 6, or bias charges stored in capacitors provided in the drains 12 of FETs 12 are injected into the signal lines 4, reading is performed. By this constitution, even when the reference potentials of vertical signals disperse in every array, fixed pattern and random pattern noises remarkably reduce and thus a high sensibility can be obtained, if the reference potentials at the time of emitting excess charges and reading are in a slight difference at each signal line 4.

Abstract: PURPOSE:To make it possible to sterilize a water line by leading an aqueous hydrofluoric acid solution with a specific concentration to a superpure water line and to prevent water containing fluorine ion from being discharged outside by using an ion-exchange resin and remove the fluorine ion efficiently after sterilization. CONSTITUTION:To carry out sterilization, the amount of pure water in a tank 1 is adjusted and HF is injected to the tank.

After a bypass connection not passing through a polisher 6 is formed, a circulating pump 4 is operated, the aqueous HF solution is circulated in the superpure water line order to sterilize the line. Each duct is connected to an inlet and an outlet of a cartridge-type anion-exchange resin polisher in which a basic anion-exchange resin is packed and then the circulating pump 4 is operated. Then, the solution is circulated again so as to adsorb F<-> ion in the anion-exchange resin from an aqueous HF solution which has already worked for sterilization in the line.
