Title: Copying method using laser
Inventor: SEGAWA HIDEO
IPC: G03G13/04
Filed: 1978-02-07
Abstract: PURPOSE: To make it possible to increase the copying speed and the resolution, as compared with the conventional method, by setting a plurality of optical fibers into a main scanning line.  
     CONSTITUTION: The laser flux of light A from a laser source 3 is periodically deflected by a rotary polygonal mirror 5, and a cylindrical lens 7 is used so that the original O upon its carriage 1 is condensed for main scanning purposes in the direction of arrow P into a slit shape which has a small length and a very small width. The original carriage 1 is auxiliary scanned in the direction of arrow T by a rack 1a and a pinion 2. A condensing array 9 of optical transmitting elements are arranged with respect to the band-shaped locus of the condensing portion in the main scanning direction so that the optical image is received while arranging in contact the optical transmitting members 8 made of five optical fibers and converted into electric signals by means of light receiving elements 9a which are arranged at the emanating end faces. The respective electric signals are fed to semiconductor laser arrays 10 arranged so that they are modulated in intensity into a laser beam B. This beam B is introduced into the polygonal mirror 5 so that the reflected light is used to expose a photosensitive drum 22 through a condensing lens 21 to form an electrostatic latent image corresponding to the original, thus obtaining the copies by a normal process.

Title: Ink jet recorder
Inventor: MURATA TAKAYUKI
IPC: B41J29/46
Filed: 1989-01-24
Abstract: PURPOSE:To apparently correct a void created by the defective feeding of a material to be recorded at the time of sub-scanning by providing a preliminarily jet-out orifice and a means detecting the recorded state corresponding to the preliminary jet-out orifice. CONSTITUTION:It is assumed that a pattern (a) is divided into two lines and recorded. After the 1st line is recorded, sub-scanning is carried out. Then, a head unit 1 is moved reversely to recording, and at this time a light emitting diode 4 is lit. By illuminating a recording paper area corresponding to the preliminary jet-out orifice 3, a phototransistor 5 detects the recording state of the area. Since a pattern (d) with a void is recorded if paper is excessively fed, no recorded dot is detected from the recording paper area corresponding to the preliminary jet-out orifice. When the subsequent 2nd line is recorded, an ink drop is jetted out of the preliminary jet-out orifice 3 together with a jetted ink drop from a jet-out orifice 2, and dots D are recorded as a pattern (e) shows.

Title: Magnetic head
Inventor: SUGIMORI MASAHIRO
IPC: G11B5/23
Filed: 1989-01-24
Abstract: PURPOSE:To prevent the generation of cracks by specifying the essential component of high melting glass to diminish the difference between the coefft. of thermal expansion of the high melting glass and the coefft. of thermal expansion of magnetic metallic films and ferrite cores. CONSTITUTION:A gap 3 formed by combining the two ferrite cores 1, 2 is joined by bonding glass and the high melting glass 5 to determine the gap width and the magnetic metallic film 4 are provided in the gap. The material of the high melting glass 5 is so formed as to consist essentially of SiO2 and to contain 5 to 40wt.% >=1 kinds among CaO, BaO and SrO in addition thereto. The coefft. of thermal expansion of the high melting glass is, therefore, higher than the coefft. of thermal expansion of the high melting glass consisting of the SiO2 alone and is approximated to the coefft. of thermal expansion of the ferrite cores and the magnetic metallic film. The generation of the cracks arising from the difference in the coefft. of thermal expansion between the respective materials is suppressed in this way.
