Title: Surface acoustic wave device
Inventor: MORISHITA HIDEYA
IPC: H03H9/25
Filed: 1989-03-02
Abstract: PURPOSE:To suppress ripple and spike voltage at the outside of a pass band in the frequency characteristic while using a square surface acoustic wave substrate by providing a step to end faces of the surface acoustic wave substrate. CONSTITUTION:A step 21a is provided to both end faces 21 of a rectangular surface acoustic wave substrate 2 so as to be stepped down from the surface side on which electrodes 3, 4 or the like are provided. The step 21a is given to the surface acoustic wave substrate 2 in this way. Thus, a ripple or spike voltage at the outside of the pass band in the frequency characteristic is suppressed. This is because the reflecting position of a surface acoustic wave or a bulk wave at the end faces 21 is divided into two positions by giving the step 21a, thereby dispersing the occurrence of the ripple or spike voltage.

Title: Discharged sheet stacking device in sheet printer
Inventor: HOSHI TOSHIO
IPC: B65H31/30
Filed: 1987-03-09
Abstract: PURPOSE:To facilitate the take-out of paper and to reduce paper loss by forming a four joint linkage with a board assembly provided with a discharged sheet stacking board and links supporting both ends of the board assembly so that the parallel motion of the linkage is associated with a standing and falling motion of a paper guide, and by providing a roller on the base section of the paper guide. CONSTITUTION:Discharged sheets are dropped onto and stacked on a board 21 at a higher position. When a predetermined number of discharged sheets are stacked, a four joint linkage composed of a board assembly 20 and links 17, 18 is moved by feeding oil into a hydraulic cylinder 14 so that the board 21 is moved in parallel, obliquely downward. Then, the front end part of the board 21 is projected from the opening of a frame 1 while a paper guide 38 falls down associatingly. Due to the fall-down of the paper guide 38, a roller in the base section of the paper guide 38 the leading end of the stacked sheets is raised to obtain a gap between the paper guide 38 and the board 21. Accordingly, human fingers are inserted into the gap to grip the leading end of the sheets, and therefore, the sheets are taken out from the printer. After the take-out, the above-mentioned steps are repeated in the reverse order to set up the original condition. Thereby it is possible to reduce paper loss since the sheets may be taken out without the sheet being slid on the paper guide 38.

Filed: 1983-03-30
Abstract: PURPOSE:To offer a semiconductor circuit with ease of design and manufacture and especially less in element characteristic due to a radiant ray or the like by constituting a circuit having a hysteresis characteristic with far less number of elements in comparison with those of a conventional circuit. CONSTITUTION:When an input signal VIN is zero, a transistor(TR) T33 is turned on, a TRT32 is turned on, a TRT31 is turned off and an output voltage Vout is a Vcc. Even if the VIN is increased, the T33 is turned off and the T32 remains turned off in the range of VIN<Vcc-VTPD (where VTPD is a threshold voltage of the T33), and the output voltage is nearly the Vcc. When the VIN is in the range of VIN=VIH>Vcc-VTPD, the T33 is turned on, a voltage VA at a point A is increased rapidly so as to turn off the T32 and to turn on the T31 and the output voltage becomes zero. Then, when the VIN is decreased from the VIH, since the T33 is turned on, the voltage VA of the point A falls down succeedingly and when the VIN is in the range of VIN=VIL<Vcc-¦ VTPD¦, the T33 is turned on and the T31 is turned off and then the relation of Vout=Vcc is obtained again.

Abstract: PURPOSE:To stably concentrate sludge with the high efficiency of concentration, by repeating the intermittent injection of sludge that the injection of the sludge into a flotation-thickening tank is continued for a predetermined time and then suspended for a predetermined time while continuously pouring pressurized water into said tank. CONSTITUTION:Raw sludge 8 is supplied to a pressure flotation-thickening tank 1 by a sludge-supply pump 2, while pressurized water 7 is formed in a tank 3 for pressurized water by forcibly introducing air 6 to the part of water 10 from a pressure pump. The pressurized water is supplied together with the raw sludge 8 to the pressure flotation-thickening tank 1. The raw sludge 8 and the pressurized water 7 having flowed into the pressure flotation-thickening tank 1 adhere to fine gas bubbles and begin to float up. The floating sludge forms a sludge layer 9a below the surface of water at first, but the sludge is still under a swollen condition. According to this method, the efficiency of thickening the sludge can be remarkably enhanced by performing the intermittent injection of the sludge into the flotation-thickening tank while continuously pouring the pressurized water into it.

Abstract: PROBLEM TO BE SOLVED: To operate a communication equipment for a plurality of frequency bands such as GSM 900MHz and DCS 1800MHz or the like by eliminating the need for a mixer for each frequency band. SOLUTION: In a radio telephone set of dual band GSM/DCS 1800, a frequency injected to a local oscillator 228 for both bands is given from synthesizer filters 222, 422 to a mixer 234. Thus, a duplex and matching condition to a mixer input is simplified and a signal loss is minimized. A common output port of a GSM RX/LO synthesizer filter and a DCS RX/LO synthesizer filter is duplexed to the mixer input. Moreover, In the input impedance matching to the mixer 234, impedance matches a reception signal at each band and RF is trapped at an intermediate frequency. In an output matching of the mixer 234, it is designed that the impedance of the IF filter matches and a low impedance is provided to an RF input frequency.
