Title: Optical scanner
Inventor: KATAOKA KEIJI
IPC: G02F1/335
Filed: 1983-12-28
Abstract: PURPOSE:To execute an optical scanning with a high accuracy by a high resolving point number on one straight line by providing a detector for detecting a part of a laser light scanned by an optical deflecting element, with regard to an optical scanner which is suitable for a laser printer, etc. CONSTITUTION:The respective optical deflecting elements 18 execute an optical scanning as shown in a direction 19, and as a result, one scanning line 16 is formed. The scanning line 16 is formed in the vicinity of a focal line of a cylindrical lens 8, therefore, it can be formed with a high accuracy as an optical scanning line of one straight line on the optical scanning line generated by the respective deflecting elements, even if optical deflecting elements 18-1, 18-2 and 18-3 generate a position shift in the direction vertical to the arranging direction. A part 15 of a laser light to which the respective optical deflecting elements 18 execute an optical scanning in the direction 19 is detected by a photodetector 14 through a mirror 13. A position matching of the horizontal direction is executed with a high accuracy by adjusting a delay time between a signal detected by the photodetector and a timing for making a laser 1 emit a light.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To perform high-precision adaptive control while suppressing an increase in operation quantity even if an actual idle time increases by making an adaptive controller correspond to an idle time shorter than the actual idle time and also making the sampling period of an input vector of an adaptation parameter adjusting means correspond to the actual idle time. SOLUTION: An adaptive control (STR) block consists of an STR controller which sets an adaptation correction coefficient KSTR so that a target air fuel ratio coefficient KCMD(k) and a detected equivalent ratio KACT(k) match each other and an adaptation parameter adjusting mechanism which sets an adaptation parameter used here. Here, the STR controller is so constituted that an idle time (d) corresponds to three control cycles at the time of designing and the sampling period of the input vector ζ of the adaptation parameter adjusting mechanism corresponds to the actual idle time d (e.g. 5). Consequently, adaptive control can be performed without increasing the degrees of the STR controller and adaptation parameter adjusting mechanisms.

Title: Flat surface emission type electric discharge lamp
Inventor: TAMURA SATOSHI
IPC: H01J61/30
Filed: 1989-09-22
Abstract: PURPOSE:To consume less electric power while stabilizing and uniformalizing the brightness of a luminous surface by providing a closed container with No.1 electrode arranged on the inner surface of No.1 glass sheet, No.2 transparent electrode arranged on the outer surface of No.2 glass sheet and with a fluorescent film formed on the inner surface of either one of said glass sheets. CONSTITUTION:In a closed container 6, No.1 transparent square glass sheet 7 is faced to No.2 glass sheet 8 in parallel, No.1 glass sheet 7 includes No.1 membranous electrode 10 on its inner surface, No.2 glass sheet 8 includes No.2 transparent membranous electrode 11 on its outer surface, and furthermore, a fluorescent film 12 is formed on the inner surface of No.2 glass sheet 8. When high voltage is applied between No.1 and No.2 electrode 10 and 11, sparks occur in a discharge space between No.1 and No.2 glass sheet 7 and 8, and the fluorescent film 12 is made luminous so as to start lighting. This thereby causes sparks to occur uniformly in the whole of the discharge space so as to start lighting while the brightness of the luminous surface can be uniformly distributed within the closed container. In addition, since rare gas enclosed in the container, is excited by AC electric fields so that lighting is started, brightness is stabilized with low electric power consumption.

Abstract: PURPOSE:To prevent disabled feeding and damage of paper, by moving a carriage such that a print paper is bent to a platen side by means of a paper guide when a signal for feeding the print paper is inputted while accompanying no print operation. CONSTITUTION:After a print paper is fed through rotation of a platen 2 and the tip thereof reaches a position corresponding to a press roller 5, a paper feed signal is inputted while accompanying no print operation, thereby when the press roller 5 is returned to the direction toward the platen 2, the press roller 5 may float from the platen 2 because of the rigidity of the print paper. In such a case, a carriage 12 is moved at least prior to collision of the tip of print paper against a cover 17 so as to bend the print paper toward the platen 2 by means of a paper guide 16, thereafter the platen 2 is rotated to feed the print paper. Consequently, the tip of paper can be directed reliably toward the discharge port side thus preventing disabled feeding or damage of paper.
