Title: Ultrasonic treatment apparatus
Inventor: NONOYAMA NOBORU
IPC: C02F11/04
Filed: 1989-04-24
Abstract: PURPOSE:To make ultrasonic treatment continuous with high efficiency by allowing fine inorg. particles to be present in a treatment tank equipped with an ultrasonic vibrator in a non-fixed state and mounting a screen not permitting the inorg. particles to pass to the sludge discharge port of the treatment tank. CONSTITUTION:Sludge is supplied to a treatment tank 1 from a sludge supply port 2 though a screen 5 and an ultrasonic vibrator 4 is operated while only the sludge is discharged from a discharge port 3 through a screen 6 by supply pressure. Fine particles 10 are continuously or intermittently supplied to the treatment tank 1 from a fine particle supply pipe 9 and the supply amount of the fine particles 10 is set to the amount corresponding to the wear amount thereof accompanied by ultrasonic treatment. The sludge and fine particles 10 in the tank 1 are mixed by the action of the ultrasonic waves emitted from the ultrasonic vibrator 4 and the solubilization of the sludge is further accelerated by the fine particles 10. The particle size of the inorg. fine particles allowed to be present in the treatment tank is pref. set to 0.2mm or below.

Title: Optical transmission switch
Inventor: IMOTO MASATAKA
IPC: G02B26/08
Filed: 1982-06-14
Abstract: PURPOSE:To enable optical transmission at a bending place by making light beam incidence in two directions at the Bragg angle upon an optical deflecting element fixed in a housing, and connecting optical fibers to positions corresponding to its primary diffracted projection light and zero-order diffracted projection light. CONSTITUTION:The switch consisting of an optical deflecting medium element 5 made of tellurium dioxide, transducer 8, and ultrasonic wave absorber 9 is fixed in the housing 16. When the optical deflecting element is turned on by being applied with an ultrasonic wave, incident light from the optical fiber 14 strikes the optical deflecting element 5 at the Bragg angle theta to obtain the primary diffracted projection light diffracted at an angle 2theta, which is guided to an optical fiber 19 through a concave lens 17 and a reflecting mirror 18. The primary diffracted projection light obtained similarly from incident light from the other optical fiber 15 is guided to an optical fiber 20, thus spreading and separating the two light beams. Once the optical deflecting element 5 is turned off by an ultrasonic wave signal, the light from the optical fiber 14 is sent to the optical fiber 20 and that from the optical fiber 15 is sent to the optical fiber 19.

Abstract: PURPOSE:To improve the stability of a reading action and to shorten the cycle time by turning on a coupling transistor which short-circuits a pair of digit lines in a precharge mode to inactive a sense circuit and then turning off the coupling transistor after the precharge mode to actuate the sense circuit. CONSTITUTION:Digit lines D and -D are precharged at the same potential with arrival of a coupling signal phiC and immediately after the start of precharge. At the same time, sense nodes A and B are also precharged at the same potential. When the precharge is ended [t=phiL, phiC (OFF)], the potential of both nodes A and B drop at the same level with supply of electronic charges given from lines D and -D. Then the difference voltage is obtained by receiving the effect of a dummy cell as well as a memory cell at and after the drive mode [t=phiW, phid (ON)] of the address and dummy address signals. The node B of a high potential is set at the potential of the line -D with the drive [t=QS (ON)] of the sense signal. While the node A of a low potential drops down to a low potential of a power supply together with the line D. This low potential is written to the memory cell of the address which is read out in the form an information signal. Then a refresh action is carried out.
