Title: Image forming device
Inventor: MIMURA SUEFUMI
IPC: G03G15/02
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To prolong the life of respective device by restraining carrier attraction onto a photoreceptor occurring at the time of re-throwing main power source right after cutting off the main power source, in an image forming device adopting the two component reversal developing device, and preventing damage on the photoreceptor and a peripheral equipment caused by the carrier sticking. SOLUTION: This device is allowed to expose/eliminate the imparted static charge before cutting off the main power source by a laser emitting device 12, at the time between the normal rotation and succeeding reverse rotation of the photoreceptor at the time of re-throwing the main power right after cutting off the main power source. The carrier attraction onto the photoreceptor caused by the static charge imparted right before cutting off the main power source is prevented by starting the pre-runing operation or the image forming operation by driving the developing device placed opposite to the photoreceptor.

Title: Narrow band laser
Inventor: SUZUKI AKIHIRO
IPC: G01J3/26
Filed: 1988-03-14
Abstract: PURPOSE:To reduce the shift of a laser oscillation wavelength by a method wherein a position on the surface of an ethalon to which a laser beam is applied is varied with time and reduce the unbalance of a temperature distribution in the ethalon. CONSTITUTION:An ethalon 5 which is one of light emitting elements is inserted into an optical resonator composed of mirrors 2 and 3 in a laser oscillator. The wavelength band of the laser oscillation is narrowed and its center wavelength is limited to the wavelength determined by the ethalon. At that time, a rotary shaft 7 is attached to an ethalon holder 6 and, by a rotation driving system 8, the ethalon 5 is rotated with the holder 6 at a speed of one revolution per several minutes. With this rotation, the position on the surface of the ethalon 5 through which a laser beam passes is varied so that local thermal strain can be relieved. With this constitution, the shift of the laser oscillation wavelength can be reduced.

Title: Spectroscopic apparatus
Inventor: EGUCHI TOSHIYASU
IPC: G01J3/06
Filed: 1988-03-15
Abstract: PURPOSE:To uniformly maintain measurement accuracy by executing wavelength scanning by a combination of a liquid crystal panel and thin films having spectral characteristics. CONSTITUTION:Incident light 6 from an incident slit 1 is collimated by a collimator lens 8 to approximately collimated beams of light which are then projected to the liquid crystal panel 10. The polarization direction of the incident collimated beams of light is continuously changed by continuously increasing or decreasing the value of the voltage inputted to a pair of electrodes 14A, 14B of this panel 10 and the polarized light is projected onto a transparent substrate 12. Multilayered dielectric films 11 are formed on the substrate 12 and the light projected to the multilayered films 11 receives the influence of the dielectric constant at the boundary face of the low-refractive index material film and the high-refractive index material film in the oscillation direction of the light at the time of reflection and refraction in said films and is, therefore, spectrally split. The light 13 spectrally split and diffracted by the multilayered films 11 is condensed by a condenser lens 9 and is imaged by an exit slit 2. The measurement accuracy is thus uniformly maintained.

Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To enable a user to recognize the contents of transactions more clearly, following the orders by sequentially displaying the printed content by an image displaying means for every time when the transaction data are recorded (printed) on a bankbook. SOLUTION: When a user inserts a bankbook into a bankbook insertion entrance and performs a prescribed operation that should execute a transaction accompanying bankbook recording, unregistered data are sent from a host computer 10 and are received. Whenever one line corresponding to one item of the transaction is printed, the end of the bankbook recording processing is decided after the printed content for the one line is displayed on a display 7. Then, when all of the unregistered data sent from the computer 10 are not printed, return to elimination decision on a screen. Thus, the elimination decision on the screen, the printing one line on the bankbook which follows it and the screen display of the printed content for one line are repeatedly carried out and the printed contents displayed on the screen are increased gradually.

IPC: G02F1/133
Filed: 1994-03-30
Abstract: PURPOSE:To improve a lighting property without changing luminance and power consumption by controlling the power source of an inverter, converting a direct current into an alternating current to be applied to a cold cathode tube, to make lighting voltage higher at the time of low temperature than that at the time of ordinary temperature and shorten the lighting period of dimming. CONSTITUTION:A voltage control circuit 1 and a dimming circuit 3 use respective switching regulators 8 and 9 to control transistors 2 and 4 to control the connection/disconnection of input voltage and electric power to an inverter 5. Corresponding to this input voltage and connection/disconnection, the inverter 5 applies A.C. voltage of a constant frequency to a cold cathode tube 6 with which a temperature sensor 7 is made in contact to light the cold cathode tube 6. Associating with the detected temperature of a sensor 7, in low temperature more than in ordinary temperature, the circuit 1 increases output voltage, and the circuit 3 shortens the period of the connection of dimming by the connection/disconnection set by a variable resistor 10. This can improve the lighting property of the cold cathode tube 6 in low temperature without changing luminance set at initial stage and power consumption.

Abstract: PURPOSE:To avoid mixing of liquids as much as possible in changing over the supply of a liquid to be treated and the supply of an extrusion liquid by a method wherein the liquid to be treated is supplied from a part directly above a filler bed and the extruded liquid from an upper part parted from the filler bed. CONSTITUTION:The feeder 4 for a liquid to be treated is arranged directly above the filler bed 2 comprising a separating carrier in a separation tower 1 and an extrusion liquid feeder 5 to a place in an upper large space 3 parted from said filler bed 2. In carrying out the change-over of the liquid to be treated and the extrusion liquid in this condition, when the extrusion liquid is introduced into the feeder 5 and the liquid to be treated is supplied while a liquid is withdrawn from a liquid collecting apparatus 7, because both liquids are different in specific gravity, the layer of the liquid to be treated is formed on the upper surface of the filler bed 2 and the extrusion liquid is present in the space part 3. As described above, even if the liquid to be treated and the extrusion liquid are changed over, both liquids are scarecely mixed.
