Title: Electric equipment with momentary reduced voltage operation guarantee
Inventor: ETO TOKUO
IPC: H02J9/06
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To suppress the power consumption of electric equipment with momentary reduced voltage operation guarantee. SOLUTION: When the rated voltage of a commercial AC power source is applied and a commercial AC power source has a voltage below a designed guarantee minimum AC source voltage, the voltage Vi1 of an electrolytic capacitor 21 is held above 5.3 V (= an operation guarantee minimum input voltage as to a 5V automatic voltage generator 24) only with the discharging current from a secondary coil 14 and a diode 30 is off. When the commercial AC power source drops almost to the designed guarantee minimum AC source voltage, the diode 30 turns on and the electrolytic capacitor 21 receives even the charging current from a 6 V automatic voltage generator 29, so that Vi1 is held above 5.3 V.  While Vi1 is thus held above the operation guarantee minimum input voltage of the 5 V automatic voltage generator 24, it is held relatively small and the power consumption of the 5 V automatic voltage generator 24 is suppressed.

Abstract: PURPOSE:To obtain a laminated aluminum material whose close contact property, insulating property and corrosion-resistant property of an organic film are excellent by a method wherein, after one side or both sides of an aluminum material have been coated with an adhesive which contains an olefin-based copolymer and an aziridine compound, an olefin-based resin layer is laminated and this assembly is heated at the melting point or higher and at the decomposition temperature or lower of the adhesive layer and the resin layer. CONSTITUTION:An olefin-based adhesive is used for a resin layer which is laminated on one side of both sides of an aluminum material. An olefin-based copolymer as a main agent is used for an adhesive; the range of an aziridine compound is set at 0.5 to 15% with reference to 100 pts.wt. of the olefin-based copolymer. In order to enhance a close contact property after a drawing working operation, a heating treatment is executed to heat the adhesive layer to a temperature at the melting point or higher and at the decomposition temperature or lower of the adhesive layer and the resin layer after a laminating operation. The laminated aluminum material for electrolytic-capacitor case use is excellent in its corrosion-resistant property and its insulating property and is excellent also in its close contact property by the drawing working operation and in its close contact property at the working temperature of an electrolytic capacitor.

Title: Electrophotographic device
Inventor: SHIRAI MASAHARU
IPC: G03G15/02
Filed: 1986-12-04
Abstract: PURPOSE:To prevent an image from tailing, blurring, and voiding by providing a screen member which has a specific aperture rate and an alkaline film consisting of alkali metal silicate and a conductive material on the photosensitive body side of a corona electrostatic charger. CONSTITUTION:The screen member 3 which has a 45-75% aperture rate and the alkaline film consisting of alkali metal silicate and a conductive material is provided to the corona charger 2 on the photosensitive body side. When the aperture rate is made small, an electrostatic charging potential becomes too low and when the aperture rate is too large, the amount of NOx reaching the surface of the photosensitive body increases and the reduction effect of NOx is lessened greatly. The effective aperture rate is preferably 60-70% and the film thickness is 75-100mum. Consequently, Nox produced by negative corona discharging is adsorbed efficiently, chemically, and fixed to charge the surface of the photosensitive body electrostatically with negative ions which are free from NOx, thereby eliminating the tailing, blurring, white absence, etc., of the image.

Title: Information recording medium
Inventor: YAMADA KATSUYUKI
IPC: G11B7/24
Filed: 1990-10-29
Abstract: PURPOSE:To achieve a longer life of recording eliminating degrading owing to oxidation or the like of a heat radiation layer as caused by the repetition of recording and erase by employing a hard carbon film with a heat conductivity controllable optionally in a wide range as heat radiation layer on an information recording medium to optimize the speed and sensitivity of recording and deletion.

Here, the hard carbon film 5 comprises a hard carbon film which contains at least one of amorphous and fine crystalline substance having a carbon atom and a hydrogen atom as main composition element. As the film is a gaseous phase growth film, physical qualities can be controlled in a wide range depending on conditions of film formation thereby obtaining higher recording sensitivity and erase ratio. This enables a high speed recording and a high speed erase and moreover, this eliminates degrading in C/N ratio as caused by the repetition of the recording and erase.

Title: Electrophotographic recorder
Inventor: INOUE TAKAHIRO
IPC: G03G15/08
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To improve a printing grade without generating fog by applying a voltage only to a conductive part selected according to the width of a paper sheet. SOLUTION: When an operator controls a control panel to set the size of the paper sheet, the output part of a transfer high-voltage power source is selected according to the size of the paper and a transfer voltage is applied to the corresponding conductive parts 49A to 49C from the selected output part. At the time of printing an A4-size paper for instance, the transfer voltage is applied to all the conductive parts 49A to 49C. At the time of printing an A6-size paper, the transfer voltage is applied only to the conductive part 49B. Thus, in a transfer roller 48, the transfer voltage is applied only to a range corresponding to the width of the paper, so that the transfer voltage never leaks to a low impedance part. Since a high voltage is not directly applied to the transfer roller 48, the life of the transfer roller 48 can be prolonged.

Abstract: PURPOSE:To prevent a bad influence due to the noise of a video signal correcting device by switching a switch circuit not to operate an amplitude correcting circuit at the time of exceeding a prescribed reference voltage due to mixture of the noise to a video signal. CONSTITUTION:If an excessive noise is mixed with the video signal and the voltages generated by an amplitude detecting circuit 1 and a high band component detecting circuit 3 exceed reference voltages of reference voltage generating circuits 11 and 21, this state is detected by comparator circuits 12 and 22 to switch circuits 14 and 24 to the side of constant voltage generating circuits 13 and 23. Then, a constant voltage is supplied to an amplitude correcting circuit 2 and a high band component correcting circuit 4, and the correcting operation is not performed. Consequently, the phenomenon is prevented that extents of correction in the amplitude correcting circuit 2 and the high band component correcting circuit 4 are made unstable to disturb the amplitude and the high band characteristic of the video signal.
