Title: Semiconductor laser scanner
Inventor: OSHIMA MASAAKI
IPC: H01S5/40
Filed: 1989-03-23
Abstract: PURPOSE:To oscillate in-phase laser beam at high speed by arranging semicon ductor lasers at a distance where laser oscillation beam energy can be coupled and inputting light energy to the semiconductor lasers from outside in a biased state. CONSTITUTION:When input light 13 is made incident, oscillation laser beam 14 is obtained and the oscillation leak light of the laser light 14 gives an adjacent laser a gain and is coupled to oscillate laser beam 15 and 16, so that laser beams 17-20 are oscillated. When a biased light receiving device 22 is connected and variable resistors 24 and 25 are adjusted, all the lasers can be stopped by the output laser beam 20 from oscillating. The lasers return to the original bias state after the oscillation is stopped, oscillate again so as to make a sequential scan with the input pulse light 13, and then stop. Consequently, the fast laser scanner which is uniformed in the phase of an oscillation vertical mode can be obtained.

Inventor: IDEI KOJI
IPC: B41M5/52
Filed: 1994-04-08
Abstract: PURPOSE:To improve ink absorption capacity without damaging the density, feathering aptitude and sharpness of a recorded image by controlling the ink permeation time of an ink jet recording sheet within a specific range. CONSTITUTION:An ink jet recording sheet with a basis wt. of 60g/m<2> is stationarily placed on the liquid surface of ink jet recording ink and the ink is allowed to permeate the sheet from the surface on the liquid surface side of the recording sheet to the opposite surface thereof.

Title: Thermal transfer printer
Inventor: KOMURO KIYOTO
IPC: B41J17/30
Filed: 1987-03-25
Abstract: PURPOSE:To enhance printing quality by making it possible to release an ink film after recording and recording paper at a predetermined position, by pressing a film release roller by a film guide roller to prevent the levitation of the film release roller. CONSTITUTION:In such a state that there is no film guide roller 6, film tensions F1, F2 act on a film release lever 11 to allow a film release roller 5 to escape in an F3-direction around a point B. When the film guide roller 6 is mounted, the resultant force F3 of the tensions F1, F2 goes toward the fulcrum B-direction without changing the position of a film take-up core 7 and, therefore, the variation in the pressing force of the film release roller due to the variation of the film tensions is eliminated and good recording free from the irregularity of a paper feed pitch is obtained and space efficiency does not also change. Further, the variation in the film tensions when a film take-up directions is a C- direction is absorbed by the expansion and contraction of a film guide spring 14 and the change in the pressing force of the film release roller is not generated. Therefore, the printing irregularity due to the release of an ink film 1 and recording paper 2 is not generated.

Title: Cleaning method of roller of printer
Inventor: IISAKO HIROSHI
IPC: B41J29/17
Filed: 1989-03-23
Abstract: PURPOSE:To improve the working efficiency and to shorten the working time by rotating and stopping rollers independently for each group, so that said rollers in the group are allowed to slip on a paper, thereby wiping the contamination thereof by said paper. CONSTITUTION:In the state where a paper 1 is set in contact with every roller, a first group 7 is rotated in a normal direction 6a, and simultaneously, a second group 9 is stopped. Since the paper 1 is held by each pair of rollers 4, 5 in the stopped second group 9 in this case, it is not forwarded (in a direction F). Therefore, rollers 2, 3 in the first group are rotated in vain, skidding on the paper 1. As a result, the ink and dusts etc., on the rollers 2, 3 are wiped by the paper 1. Thereafter, the first group 7 is stopped, and the second group 9 is rotated in an opposite direction 6b. Thus, the rollers 4, 5 can be wiped off the dusts etc.

Title: Production of can body excellent in impact resistance
IPC: B21D22/20
Filed: 1992-03-27
Abstract: PURPOSE:To improve the impact resistance of a can body when a laminate steel sheet not necessarily requiring coating is used as the material of a 2-piece can in the field of container. CONSTITUTION:A plated steel sheet coated with an amorphous polyester resin film at least on one side is formed into a can body by drawing-ironing or drawing-stretching processes in such a manner that the coated side serves as the can interior. The can interior is irradiated with electron beams at a dose of 1-500Mrad in a substantially oxygenless atmosphere. Electron beam radiation causes a three-dimensional cross-linking of the resin, preventing the resin film from changing into a brittle crystalline matter during the thermal treating of the can body.
