Title: Laser scanner
Inventor: KAWADA NAOKI
IPC: G02B26/10
Filed: 1988-08-06
Abstract: PURPOSE:To synchronize main-scanning and sub-scanning, and to enable the write start of a picture from a desired position in the direction of sub-scanning by using a pulse motor as the driving source of a sub-scanning driving means and driving the driving motor of a polygon mirror and the pulse motor by employing the same fundamental clock signal. CONSTITUTION:A rotating disk 33 is rotated and positioned at a specified position, and a picture on a liquid crystal panel 51 for yellow exposure is projected and exposed to a photosensitive film 21. When the upper section of the film 21 is irradiated with required energy, the rotating disk 33 is turned, a picture on a liquid crystal panel 52 for cyan exposure is projected and exposed onto the same photosensitive film 21, and the pictures for yellow and cyan are superposed and synthesized. Likewise, pictures for yellow, cyan and magenta are superposed onto the photosensitive film 21 and exposed. The positions of the write start of pictures onto each liquid crystal panel 51-53 are aligned by a photosensor 8 in the main-scanning direction and a pulse motor 39 and a write timing in the sub-scanning direction at that time. Accordingly, color drifts are not generated in the pictures for yellow, cyan and magenta on the film 21.

IPC: H03F3/45
Filed: 1990-07-23
Abstract: PURPOSE:To obtain the noise suppression effect with less dispersion in the characteristic by forming the amplifier with two diodes connected to each collector of two transistors(TRs) being components of a differential amplifier and one common current source connected in common to the two diodes. CONSTITUTION:The anode of a 1st diode 13 is connected to a 1st output terminal 11, the anode of a 2nd diode 14 is connected to a 2nd output terminal 12, and cathodes of the two diodes are connected to a common connecting point 18.

Title: Ink jet recorder
Inventor: SENZAKI MASAMI
IPC: B41J2/075
Filed: 1990-07-27
Abstract: PURPOSE:To obtain an ink jet recorder capable of conducting an ideal recording without a possibility that a satellite may adhere at and around a delivery port of a delivery surface by providing power sources respectively connected to first and second electrodes for applying voltages of the same polarity. CONSTITUTION:Voltages are applied to an electrode 11 being in contact with conductive ink 16 and a ring-form electrode 13 surrounding a delivery port 17 respectively by power sources 12, 14. By driving an electrothermal energy conversion body inside a nozzle 10, a part of the ink 16 is heated, and a bubble is produced. The bubble causes an ink liquid drop to deliver out of the delivery port 17. The liquid drop starts flying toward a recording medium 15. At this time, the ink liquid drop to be delivered is strongly electrified to have positive charges. Therefore, both a main drop and a satellite have positive charges. Because the positive voltage is applied to the electrode 13 surrounding the delivery port 17, the satellite is electrostatically repulsed against the electrode 13. As a result, the satellite is prevented from adhering at and around the delivery port 17 of the delivery port.

Title: Control method for electrophotographic device
Inventor: INAMOTO KIYOSHI
IPC: G03G21/00
Filed: 1988-08-08
Abstract: PURPOSE:To facilitate the control of action timing and abnormality detection by setting a timer at a value obtained by dividing the making one turn time of a photosensitive body by N, performing a prescribed action whenever a timer outputs and comparing a mark signal corresponding to one turn of the photosensitive body with N-timer signals. CONSTITUTION:The value is obtained in such a way that the time required for the photosensitive body belt 2 having an area in which an image cannot be formed to make one turn is divided by N, and the timer 17 is set at the value. The photosensitive body belt 2 is provided with a reference position mark hole, which is detected by a mark sensor 16. Whenever the timer counts up the N-divided value, each part of an electronic device 1 performs a prescribed action. In case the mark sensor 16 generates a signal before the timer counts up the N-value corresponding to the making one turn of the photosensitive body belt 2, a process controller 20 detects abnormality. Thus, the control of action timing is facilitated to prevent malfunction.
