Inventor: FUKUCHI HIROMICHI
IPC: B41J2/045
Filed: 1983-07-04
Abstract: PURPOSE:To facilitate the formation of a multi-nozzle while shortening an ink filling time, by separating the flowline system of a pressure wave generating means and an ink filling flowline system. CONSTITUTION:A first ink supply part 15 comprising a common thin layer is arranged between each pressure wave generating chamber 11 and an ink tank 6 while a capacity chamber 13 having a volume smaller than that of the pressure wave generating chamber 11 is provided between each pressure wave generating chamber 11 and a nozzle 10. In this case, a printing head is constituted of the capacity chamber 13, a jet channel substrate 1 provided with an ink supply orifice 13-1 communicated with a second ink supply part 13-2 and an ink supply passage base plate which is connected to the jet channel substrate and has a plurality of the second supply orifices 13-2, which directly communicates the ink supply orifice 13-1 and the ink tank 16, independently arranged thereto at every capacity chamber 13. Therefore, an ink equilibrium state can be held only by the ink surface tension force of each nozzle 10 and, further, ink to be replenished can be directly supplied to a head end surface through the second ink supply orifice 13-2 and the ink supply orifice 13-1 by capillary action.

Title: Active speaker circuit
Inventor: WATANABE TAKASHI
IPC: H04R1/06
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent production of a noise output from a power amplifier circuit by nullifying a power control signal when the floating state of an input side pre-grounding terminal is detected. SOLUTION: When an input connection code 3 is not connected while a connecting code 7 connects a set body side 1 and an active speaker circuit 21, the input side of an amplifier 6a of the circuit 21 and a pre-grounding terminal 21b will be in a floating state. Since the terminal 21b is connected to a Vcc side of a power source circuit 8 through a bias circuit 33, and the Vcc voltage is applied, the terminal 21b becomes will be in the same potential as Vcc and turns on a transistor 34. As a result, because an input terminal of a standby switch 6 is grounded through the transistor 34, a control signal that is supplied from the body 1 to a control input terminal 21c is nullified, the switch 6b is not operated and power is not fed to the amplifier 6a.

Abstract: PURPOSE: To provide the coal combustion waste gas purification equipment that prevents environmental pollution due to dust and residual SO x  by a method wherein a filtration/dust collector having filter material precoated with pulverized adsorbent particles is installed at the downstream of an adsorption column.  
     CONSTITUTION: Fuel coal is dry distilled and activated to produce an SO 2  adsorbent, part of which is pulverized by a crusher 14 and sent by a fan 15 to the filtration-dust collector 13 to precoat filter material. Waste gas from a boiler 1 is passed through the deNO x -SO 2 -oxidation equipment 3, and the produced SO 3  is adsorbed by dust which is collected by an electric dust precipitator 5. SO 2  is adsorbed by the moving layer adsorption column 7, and the saturated adsorbent is regenerated in a desorption column 10 and is returned to the adsorption column 7, whereby partly damaged pulverized adsorbent is removed in the separator 12.

Title: Pulse driver circuit
Inventor: ITOU HIROYUKI
IPC: H03K23/66
Filed: 1978-10-03
Abstract: PURPOSE:To maintain the phase and period of an output in a normal state even while a synchronizing signal is cut off, by measuring a difference in rise time between an output pulse from a free-running oscillator and then by controlling a ratio of division of a free-running oscillation output by the output. CONSTITUTION:A pulse from free-running oscillator 2 drives counter circuit 14 and is divided by 1/N-divider circuit 15, whose output is made into a pulse of duty 50% by FF16 and then outputed from terminal 4. By exclusive-OR circuit 5, OR circuit 6, monostable circuit 7, and AND circuit 8, a period when an external synchronizing signal differs in rise part from an output signal from oscillator 2 is separated and this length is subtrated by up-down counter 9 when the rise of the output signal lags or added when leading, by using as a unit pulse obtained by dividing 10 the output of oscillator 2 by a number 2 or greater. As a result, when the output signal lags, circuit 15 performs division by a number smaller than usual and when leading, division is done reversely, thereby making a shift in a direction where it agrees with the external synchronizing signal.
