Title: Service life predicting device of servo valve
Inventor: KUROHICHI TSUYOSHI
IPC: F15B13/044
Filed: 1985-04-03
Abstract: PURPOSE:To facilitate prediction of the service life of spool upto the limit of usage through motion of neutral point by detecting the neutral point of the spool of servo valve every predetermined time then comparing the detected level with a normal level under initial adjusting. CONSTITUTION:The displacement of the spool 5 of servo valve is detected through a displacement gauge 6 then compared with a setting level in an amplifier 2 and fed back to the spool 5. The neutral point of spool 5 is compared with the normal level provided from an initial level setter 10 every predetermined time set through a timer 11 to operate the time elapsed until the motion of the neutral point will reach to the limit of usage through an arythmetic unit 12 thus to indicate the time on an indicator 14.

Title: Toner concentration controller
Inventor: MARUMOTO TAKESHI
IPC: G03G15/00
Filed: 1990-03-19
Abstract: PURPOSE:To shorten a stopping time for recovering a toner density when consecutive recording is carried out by providing each means of mode setting, pausing level setting, concentration discriminating, recording action pausing, control, and pause releasing. CONSTITUTION:Switching is carried out to a multi-consumption mode by an operating part 2. When a sensor 1 is changed to a pausing level that the toner concentration is set between a control level and an empty level, or below, a CPU 11 stops a recording action only for time set in advance. The recording action is resumed after the time lapses. On the other hand, the pause of the recording action is carried out whenever one sheet is completely recorded. When the toner concentration is the control level or above, during the pause of the recording action whenever one sheet is completely recorded, the pause of the recording action is released to carry out normal recording. When toner consumption per one sheet is more than a quantity set in advance, the switching is automatically carried out to the multi-consumption mode, a pausing time is varied, and the toner consumption and a replenishing quantity are made coincident with each other. At this constitution, the stopping time for recovering the toner concentration is shortened.

Abstract: PURPOSE:To transmit the original of characters to be easily observed and to eliminate the degradation of picture quality by generating picture data in a routine size cutting one side or both sides of the original or generating the picture data in the routine size to be enlarged/reduced after being cut and transmitting the picture data. CONSTITUTION:Corresponding to an instruction from a cut control part 5, a reader part 1 generates the picture data cutting one edge or the both edges of the original at the designated position and a picture reduction/enlargement part 4 reduces/enlarges the picture data as needed to the routine size. Then, the picture data is compressed and transmitted. In such the case, the margin part or the like at the edges of the original is cut and the picture data is transmitted while being reduced/enlarged to the routine size as needed. Thus, the degradation of picture quality is eliminated and the original of the characters to be easily observed can be transmitted.

Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To surely prevent the gas leakage from a coke furnace port part by adding and mixing the prescribed quantity of material containing crystalline silicon dioxide as the aggregate with water glass. SOLUTION: The material for hot repair of a coke furnace is comprised by adding 20-60 wt.% the compound of crystalline silicon oxide as the aggregate to 100 wt.% water glass in terms of the solid, and mixing them. When the solid content in water glass exceeds 65 wt.%, the viscosity of the slurry in which the crystalline substance is added to water glass becomes higher, the transport of the repairing material for spraying, spraying from a spraying nozzle, etc., are degraded, and the execution becomes difficult. On the other hand, when the solid content is below 20 wt.%, the content of silica rock to be crystallized in the repairing material is reduced though the transport and workability of the repairing material are excellent, the crystallization ratio when heated after execution is degraded, and the desired quality of the repaired layer can not be obtained.
