Filed: 1988-12-12
Abstract: PURPOSE:To detect any defect of a finner reticle by forming a plurality of light shielding films on a plurality of regions on a surface of a transparent substrate as a mask substrate for use in checking the reticle. CONSTITUTION:A mask substrate 1 includes a Cr light shielding film 1b, an Al light shielding film 1c, and a Cu light shielding film 1d formed by deposition with a plurality of metals on a plurality of regions of a surface of a transparent substrate 1a.

Title: N to one backup controller
Inventor: KIKUCHI SEIJI
IPC: G05B7/02
Filed: 1989-12-05
Abstract: PURPOSE:To attain backup operation only by one arithmetic and control unit (ACU) and to improve the reliability and economic efficiency of the backup controller by detecting the occurence of abnormality in one ACU out of plural ones by an abnormality detector and outputting the executed result of operation. CONSTITUTION:When abnormality occurs in one of the ACUs 11a, 12a or the like, the abnormality is detected by the abnormality detector 13g and the other normal ACU executes operation and outputs the executed result instead of the abnormal ACU. Since the other normal ACU backs up the abnormal ACU, it is unnecessary to switch respective inputs/outputs by a switch like the case of an one-loop controller without doubling respective CPUs.

Title: Bromine complexing agent for metal-bromine battery
Inventor: HOSONO HIROSHI
IPC: H01M12/08
Filed: 1990-11-20
Abstract: PURPOSE:To improve energy efficiency by using N-methyl N-ethyl piperidinium bromide as a bromin complexing agent. CONSTITUTION:N-ethyl N-ethyl piperidinium bromide is used as a bromine complexing agent. The range of adding volume is used within 0.5mol/l-2mol/l. When the adding volume is not more than thin range, formation ability for a bromine complexing compound is decreased, and self discharge is caused by means of free bromine molecule. Meanwhile, when the adding volume is not less than this range, internal resistance of electrolyte is increased, and energy efficiency is diminished. Thereby, energy efficiency can be improved by proper adding volume.

Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To prevent the life of a heat exchanger from being shortened by a method wherein the number of combustion of burners is reduced when a difference between an actual number of rotation of a fan and its target number of rotation exceeds a threshold indicating a slight abnormal state during combustion of a plurality of burners. SOLUTION: A correction of the number of rotation of a fan 25 in respect of an amount of combustion ranging from No.20 to No.10 performed under an operation of a controller 30 is carried out by applying a characteristic linear line of target number of rotation- combustion amount when both burners 17 and 18 are kept under combustion state. A correction of the number of rotation of the fan in respect to the amount of combustion ranging from No.2 to No.10 is carried out by applying a characteristic linear line of a target number of rotation combustion amount in the case that only the burner 17 is kept at its combustion state.  When both burners 17 and 18 are kept at their ignited states, only the burner 17 is caused to be ignited under a control of changing-over of changing-over valves 24 and 26 in the ease that a deviation between a present value of feed-back integrated item of the number of rotation of the fan and an initial studying value is lowered than an alarm value indicating a light soot clogged site where the continued can be continued. Then, a target number of rotation Nf of the fan corresponding to each of the Nos. is corrected under application of the characteristic linear line at that time.

Title: Developing device
Inventor: SHIBATA TAKENORI
IPC: G03G15/08
Filed: 1987-12-14
Abstract: PURPOSE:To perform high-picture-quality development which is stable for a long period by providing a rotatable metallic sleeve which conveys a developer and a scraper which scrapes off a developer, and forming the scraper of a metal of different kind from the metallic sleeve. CONSTITUTION:A developer control member 4 controls the flow rate of a developer sticking on the sleeve 2 to perform excellent electrostatic charging, and the scraper 5 scrapes off a developer which still remains after an exposure latent image on a photosensitive body 1 is developed reversely. The scraper 5 needs to be brought into strong contact with the sleeve so as to increase the agitation effect of the upper and lower layers of the sleeve 2 by removing a filming material. Therefore, when the material of the same kind with the sleeve is used for the scraper, the surface of the sleeve 2 is flawed to generate an image defect. On the other hand, when a scraper 5 made of phosphor bronze is used in combination with a sleeve 2 of, for example, stainless steel, wear is small and flawing is suppressed. Consequently, high picture quality which is stable for a long period is obtained.
