Title: Energization transfer recording head
Inventor: NAKAZAWA MASAFUMI
IPC: H05K3/24
Filed: 1987-02-26
Abstract: PURPOSE:To realize minute formation of recording electrodes and improve energization properties by forming recording electrodes through application of hard chromium plating to a recording electrode pattern. CONSTITUTION:A ceramics consisting mainly of Al2O2 and MgO is used as a material for a printing head substrate 2, and a primary layer plating 3 which serves as a negative electrode consists of an electroless Ni-P plating applied on the substrate 2. Next, a negative pattern for a recording electrode is created. Then the electroless Ni-P plating is subjected to etching to form a recording electrode pattern. Following this procedure, a hard chromium plating is deposited on the electroless Ni-P pattern 3 to form a recording electrode 4. A recording head manufactured in this way has improved energization properties because of the realized minute formation of the recording electrode.

Title: Electrostatic recording device
Inventor: INOUE HIDEAKI
IPC: G03G15/00
Filed: 1990-02-23
Abstract: PURPOSE:To stabilize a high-resolution image on plain paper, to simplify structure and to improve durability by making the paper travel to an electrode opposing part where a control electrode is provided between a pair of electrodes and controlling the driving of the voltage impressed on the control electrode in accordance with recording information in a state where a bias pulse voltage is impressed on a pair of electrodes. CONSTITUTION:This bias pulse voltage having the same polarity as the electrostatically charged polarity of toner is impressed on a spiral electrode body 4. The control electrode 8 is disposed between a specified path where the toner is carried and the spiral electrode body 4 and the bias voltage having the opposite polarity to the electrostatically charged polarity of the toner is impressed on the electrode 8. a cylindrical electrode 6 is rotatably disposed on the toner carrying surface side of a toner carrying body 3 so as to be opposed to the spiral electrode body 4, and the pulse voltage having the reverse polarity to the electrostatically charged polarity of the toner is impressed on the electrode 6. Then, the bias voltage is made low in accordance with input recording information and the toner on the toner carrying body 3 is selectively transferred to the paper fed between the toner carrying body 3 and the electrode 6, so that a toner recorded image is formed. Thus, the durability is improved, the high-resolution image on the plain paper is stabilized and the structure is simplified.

Title: Driving circuit for semiconductor light emitting element
Inventor: OGAWA KATSUHISA
IPC: H05B44/00
Filed: 1992-02-28
Abstract: PURPOSE:To drive at a high speed and to eliminate noise in a driving current by connecting means for supplying a bias current to an anode end irrespective of ON/OFF of the current. CONSTITUTION:A laser diode driving current is outputted from a emitter of N-P-N transistors 4 and 5, and supplied to an anode terminal of a laser diode 7. A cathode terminal of the diode 7 is connected to an CND 9 point. A bias current setting resistor 10 is connected to the anode terminal of the diode 7. The other end of the resistor 10 is connected to a power source VCC 8. Thus, a connecting capacity of a semiconductor light emitting element is previously charged, and a connecting capacity charge current can be eliminated irrespective of a length of an OFF time. As a result, spike noise of a rise of a current waveform depending upon the OFF time suppresses deterioration of a rising speed.

Filed: 1987-02-28
Abstract: PURPOSE:To make it possible to carry out the replenishment of paper sheets in a very simple manner by providing a sheet feed guide on the sheet supply side of a bracket whose feed-out roller side is vertically movable, such that the sheet feed guide is inclined. CONSTITUTION:When sheets 70 are inserted in the direction D, the leading end of the sheets abuts against a sheet feed guide 802 so as to automatically raise a bracket 80 and a scrape-out roller 60.
