IPC: G03G21/20
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent the driving noise of a driving system and the noise of a carrying means from leaking to the outside while preventing the increase of the cost due to the increase of the number of parts and the change of appearance of a device by covering an opening part provided in a main body cover when an openable/closable paper loading member is closed with respect to a device main body. SOLUTION: On one side surface of an image forming device, a manual feeding tray 30 for supplying a transfer material different from a normal transfer paper in size and paper quality, to form a desired image on the transfer material is provided. The manual feeding tray 30 is formed to be longer than a conventional manual feeding tray 30 so that the top end part 30a of the manual feeding tray 30 has almost the same height as that of the top end part of the main body cover of the image forming device main body in the closed state of the tray 30. Sidewalls 30b are projectingly provided in both end parts in the width direction of the tray 30 to be abutted on the outside cover of the image forming device in the closed state of the tray 30, so that the noise leaking from the image forming device main body to the outside is prevented from leaking sidewards.

Title: Tone ringer circuit
Inventor: AKASHI KENICHI
IPC: H04M1/00
Filed: 1984-12-27
Abstract: PURPOSE:To prevent a tone ringer from ringing due to a dial pulse by providing a resonance preventing circuit between a telephone line and an automatic oscilation circuit provided with an automatic oscillation circuit. CONSTITUTION:A resonance preventing circuit RS 101 is connected between a telephone line 12 and a tone ringer circuit 11 provided with a self-exciting oscillator OSC using a 3-terminal piezoelectric buzzer BZ. A voltage produced across a Zener diode ZD 3 by an incoming voltage at terminals 9, 10 of the telephone line 12 is divided by resistors R 105, 106, and a voltage V1 across the ZD 103 is fed to a series circuit comprising an R 104 and a ZD 103. When the voltage across the ZD 103 is lower than the Zener voltage of the ZD 103, no current flows to the ZD 103, a transistor Q 102 is turned off and the circuit 11 is not excited. When a high ringing voltage is incoming to the terminals 9, 10, the ZD 103 is conducted, the Q 102 is turned on to ring a BZ of the OSC 11. Since the dial pulse is lower than the ringing voltage, the R 104-106 are selected so as to prevent the BZ from ringing by the dial pulse.

Title: Ink-jet recording apparatus
Inventor: HAYAKAWA MASAAKI
IPC: B41J2/055
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce a scale of a circuit for driving by impressing a voltage to a piezoelectric element at a wait time for printing or before the start of printing and deforming the piezoelectric element without changing a volume of an ink-pressuring chamber. SOLUTION: In discharging ink in an ink-pressuring chamber 27 formed of a wall A and walls B, a plus voltage is first impressed to the wall A and then a minus voltage is impressed to the walls B. In consequence, the ink- pressuring chamber 27 expands. Thereafter, a minus voltage and a plus voltage are respectively impressed to the wall A and walls B. The ink-pressuring chamber 27 suddenly shrinks, whereby the ink is discharged from nozzles thereby forming dots to a printing paper. An ink characteristic can be retained with the same frequency as a printing driving signal by outputting a driving signal which deforms the walls constituting the ink-pressuring chamber all into the same direction and vibrating the ink-pressuring chamber. A circuit constitution can be simplified without requiring a special circuit for a vibration driving signal.

Filed: 1993-11-08
Abstract: PURPOSE:To miniaturize the entire apparatus, and to easily provide a countermeasure of an electromagnetic wave interference. CONSTITUTION:A gate signal from a gate controller 13 is sent to a gate of a thyristor Tn of a lowermost stream in a switching circuit 51 through a pulse transformer PT, and the Tn is turned ON. Then, a capacitor 6 of a voltage divider Dn is discharged in a route of a resistor 5, a gate of Tn-1, a cathode of the Tn-1, an anode of the Tn, a cathode of the Tn and the capacitor 6, and the Tn-1 is also turned ON. Similarly, the Tn-2..., T2, T1 are sequentially turned ON, the circuit 51 is entirely turned On, and charge stored in the capacitor 6 is discharged. In this case, a saturable reactor 52 holds an unsaturated state until all the thyristors are turned ON, and hence no overvoltage is applied to the thyristor which is not yet turned ON.

Filed: 1988-11-02
Abstract: PURPOSE:To facilitate the forming of a conductive film by forming a dielectric block while a coupling adjustment hole is made and at least one end is choked prior to baking. CONSTITUTION:A dielectric block provided with plural throughholes 11 and a throughhole 15 for coupling adjustment arranged among them is formed by a ceramic material, at least one end of the throughhole 15 for coupling adjustment is choked by packing with a ceramic material 16 and the ceramic material 16 is baked together. Then the conductive film is formed in the throughholes 11, the outer surface and the lower face except the throughhole 15 for coupling adjustment by dipping the block into a conductor paste while the choked face is directed downward. Thus, it is possible to form a prescribed conductor film by having only to dip the block into the conductor paste. Thus, man-hour for forming the conductor film is reduced and the dielectric filter with stable characteristic is obtained.
