Title: Method for developing tank detecting doctor gap of copying machine
Inventor: MOCHIZUKI HITOSHI
IPC: G03G15/09
Filed: 1986-02-24
Abstract: PURPOSE:To improve inspection accuracy without requiring any hand by utilizing a displacement gauge and a microcomputer, and comparing a gap value found from the movement result of the displacement gauge with a proper gap value. CONSTITUTION:The displacement gauge 3 is fed by an actuator driving device 6 from an origin position 0 toward a developing sleeve 1 by prescribed distance l1. At this time, the displacement gauge 3 contacts the developing sleeve 1 and is returned by the distance of an overrun. The quantity delta1 of the returned displacement gauge 3 is inputted from a counter 4 to the microcomputer 7 and stored in a RAM 10. Similarly, the displacement gauge 3 is fed toward a control plate 2 by prescribed distance l2 and the quantity delta2 of displacement on the side of the control plate 2 is stored in the RAM 10. Then, the CPU 8 in the microcomputer 7 operates a gap value from the data stored in the RAM 10 and the prescribed movement distances l1 and l2. This value is compared with the proper gap value stored previously in a ROM 9 and when the difference exceeds a permissible value, a warning display device 14 is operated to generate a warning.

Filed: 1994-03-09
Abstract: PURPOSE:To prevent blocking-up of a strainer by arranging a filter in a dry well side opening part of a vent pipe to communicate a suppression chamber with a dry well. CONSTITUTION:A dry well 2 enclosing a nuclear reactor pressure vessel and a suppression chamber 3 containing water to condense steam at rupture time of nuclear reactor system piping, are separately formed by a diaphragm floor 4, and are communicated with each other by a vent pipe 5 penetratingly passing through these. An opening part 6 on the dry well 2 side of the vent pipe projects from the floor 4, and plural ribs 8 whose base parts are embedded in the floor 4 are arranged in a radial shape around the opening part 6, and with this, a disk shaped jet reflector 9 is supported above the vent pipe 5. The whole opening part 6 is covered with a filter 15. Now, even if a broken piece of a heat insulating material falls on a floor surface 7 of the dry well 2 and comes adrift to the vicinity of the vent pipe 5, since it is captured by the filter 15, a strainer is not blocked up by the broken piece due to this.

Abstract: PURPOSE:In a reaction of m-xylene and sulfuric acid, to obtain the titled compound useful as a binder for a mold, in high purity in high yield by prescribing a sulfuric acid concentration in a reaction time and a sulfuric acid concentration of a filtrate from which crystallized crystal of the reaction product is separated. CONSTITUTION:When m-xylene is reacted with sulfuric acid to give a solution of the reaction product, which is cooled, and crystal of m-xylene-4-sulfonic acid is crystallized, the sulfuric acid concentration in the reaction time is made 70- 78wt% (the rest is water), the sulfuric acid concentration of a filtrate from which the crystallized crystal is separated is made 70-78wt%, (the rest is water) and the filtrate is not concentrated and circulated to the reaction system as a raw material sulfuric acid. Conc. sulfuric acid, fuming sulfuric acid or sulfuric anhydride can be used as sulfuric acid, and conc. sulfuric acid is the fittest with respect to operation. The reaction temperature keeps greatly the main reaction rate, and is preferably 70-80 deg.C because side reactions such as sulfone, etc. are necessarily suppressed at low degree. The desired compound can be obtained without forming waste sulfuric acid by this process.

Title: Printing method
Inventor: ERITSUKU PII ROSU
IPC: B41J2/07
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To minimize waitbanding and to prevent the unnecessary reduction in the throughput of a printer by calculating the average time delay between passes on the basis of the experience related to an actual delay time at a time of the printing of a preceding pass. SOLUTION: A printing pass printed in respense to the command received from a page sector mechanism by a mechanism manager is shown in a drawing. A dark horizontal line 70 shows a time line and the section between one page sector (sector i+1) and a succeeding sector (sector i+2) is shown by a perpendicular line 72. Small squares like squares 84, 86 show when passes are performed along the time line 70. Since passes expand temporally as mentioned above, each pass is performed at the almost same interval as a preceding pass regardless of what page sector the pass is a part. Therefore, a result free from waitbanding is obtained.
