Title: Storage device for used paper towel
Inventor: YANAGIHARA YOSHIO
IPC: B65F1/10
Filed: 1993-04-02
Abstract: PURPOSE:To raise waste mater storing capacity by opening upper lids and an inner lids in a link motion by means of stepping a pedal and compressing waste matter (used paper towels) thrown in a storage container by virtue of the return action of the inner lids when the pedal stepping is removed. CONSTITUTION:By stepping a pedal 67 when an opening part 13 is closed by upper lids 11, 11 and inner lids 51, 51 are at the lowest position by being locked together horizontally, n arm 65 oscillates upward and, an inner lid frame 5 formed via a link elevates through a slider 63. In the course of elevation, a lock of the inner lid 51 by a lock means is released and inner lids 51, 51 are moved upward while upper lids 11, 11 are moved downward by virtue of a V shaped arm trying to open by resisting to a spring force. When waste matter is then thrown in through the opening part 13, the waste matter is stored inside a storage container 14 and, thereafter, when stepping of the pedal 67 is removed, respective members return to their original positions and the waste matter inside the storage container 14 is pressed and compressed by the inner lid 51.

Title: Uninterruptible power supply device
Inventor: NAKANO HIROTAMI
IPC: H02J9/06
Filed: 1993-04-03
Abstract: PURPOSE:To effectively suppress a harmful influence on the electromagnetic environment of a load due to the switching of an inverter by connecting the tap of a tap inductance connected to a power supply terminal in parallel to the connection point between two capacitors connected on the output side of the inverter in series. CONSTITUTION:A connection point M between capacitors C3 and C4 is connected to the tap of an inductance LT. When the connection point M is not connected to the tap, the potential of the connection point M equals the potentials of lines 7 and 8, respectively, by turning on or off the switches S1 and S3 and switches S2 and S4 each other, thus generating a high-frequency voltage between the tap of the inductance LT and the connection point M by the switching of the inverter 2 and causing the voltage between the neutral point on the side of a power supply E and the connection point M to fluctuate greatly. The tap is connected to the connection point M to suppress the fluctuation.

Abstract: PROBLEM TO BE SOLVED: To physically detect printing irregularities when the printing irregularities are fetched as images by a camera or the like by selecting and using a light source provided with the peak of spectral intensity in a wavelength area where the change rate of the light transmissivity of a colored film becomes maximum. SOLUTION: For a liquid crystal color filter by a printing method, on a glass substrate to which a black matrix for normal light shielding is vapor-deposited, the three kinds of the inks of R(red), G(green) and B(blue) are printed and the colored film is formed. The variation in the film thickness of the colored film brings the fluctuation of a transmitted light quantity and is perceived as gradation irregularities (printing irregularities). When printed matter is fetched as an image by an image fetching device, a light source provided with the peak of the spectral intensity in which the change rate of the light transmissivity of respective colorants becomes maximum. by the film thickness of the printed respective colored films is selected and used.  The change of the transmitted light quantity by the film thickness change is largest in the wavelength light of transmissivity 37% and it is preferable to select and use the light source for which the transmissivity of the light transmitted through the respective colored films is about 37%.

Abstract: PURPOSE: To prevent a barrier chamber from blocking with solid particles contained in a solvent by connecting the barrier chamber with an outlet channel via at least one of the first channels at the periphery of the chamber and connecting it with an outlet chamber via at least one of the third channels. CONSTITUTION: A solvent is fed from the periphery into a barrier chamber 6 via the first channel 11. At the same time, a barrier liquid is supplied via a channel 10 from an outlet apparatus 3. Between these two liquids, a separating zone is formed in the barrier chamber 6. If any solid particles enter the barrier chamber 6 due to a degassed solvent, they are dissolved again by a solvent which exists at the periphery of the barrier chamber 6, which will not allow the solid particles to cause malfunction of the barrier chamber 6. Besides, a solvent is constantly introduced into an outlet chamber 2 from the barrier chamber 6 via the 3rd channel 14 and the equal amount of solvent taken out from the 1st channel 11 is supplemented. Thus, the barrier chamber 6 has always new solvent so as to guarantee the entered solid particles to be dissolved.

Title: Method of initializing magneto-optical recording medium
Inventor: IWANAGA RYUICHI
IPC: G11B11/105
Filed: 1988-04-26
Abstract: PURPOSE:To prevent the degradation of the C/N of a reproduction signal by unifying the directions of the magnetization of a magnetic layer existing on guide grooves to an erasing direction. CONSTITUTION:The magnetic field of the same direction is generated by passing current to coils 5a, 5b for biasing and the magnetic layer 9 on recording tracks 7 and guide grooves 6 is irradiated by laser beams from a laser head 2 for erasing the recording tracks and a laser head 3 for erasing the guide grooves. The temp. of the layer 9 is thereby raised and the coercive force in said part is decreased. The directions of the magnetization are equally unified in the direction of the biasing magnetic field when the coercive force lowers below the biasing magnetic field of the coils 5a, 5b. The initialization is thus executed. Such initialization is executed over the entire circumference of the disk 1, by which simultaneous erasing of the tracks 7 and the grooves 6 is executed.

Title: Excess current limiter
Inventor: TANIGUCHI MASAMITSU
IPC: H02P9/14
Filed: 1982-06-15
Abstract: PURPOSE:To prevent excessive excess-current limiting action by a method wherein the case to perform excess currnt limiting action by an inverse time limit and the case to perform action instantaneously are changed over in accordance with a limiting region. CONSTITUTION:An excess current detector circuit 13a outputs a limiting signal when the armature current of a synchronous machine 1 exceeds an excess current set point. A reactive currnt polarity discriminator circuit 13e closes a contact 13h when the reactive current of the synchronous machine 1 is on the lead side. Accordingly, the limiting signal is applied to an automatic voltage regulator 2 instantaneously. While, when the reactive current is on the lag side, a contact 13g is closed, and moreover a contact 13i is closed after the time limit decided by an inverse-time circuit 13f. Therefore, the limiting signal is applied to the automatic voltage regulator 2 after the inverse time limit. Accordingly, the excess-current limiter not to perform excessive excess-current limit can be obtained.

Title: Printer
Inventor: OYAMA NAOKI
IPC: B41J2/485
Filed: 1990-04-19
Abstract: PURPOSE:To prevent deformation of an image caused attended with an increased resolution by providing a means revising the resolution of printout and a means disabling a smoothing function when the resolution //is increased. CONSTITUTION:A print data whose resolution is 600DPI is generated by a read control section 6 and a resolution controller 11 gives a command to an image forming section 12 to set the resolution of the print process system to 600DPI. When the image forming section 12 is, e.g. a laser beam printer, the resolution controller 11 sets the rotary speed of a polygon, the paper carrier speed and the laser spot system in matching with 600DPI. Thus, a transmitter in the resolution controller 11 generates a bit image transmission clock corresponding to 600DPI and sends the result to a parallel serial converter 9. Since a stop command signal is inputted from a main control section 4 in the smoothing circuit through a signal line 16, no smoothing processing is implemented to the picture of 600DPI. Thus, the picture is printed out in a way that a deformed picture is prevented.
