Title: Operation control of synchronous machine
Inventor: HASEGAWA HIROSHI
IPC: H02P9/14
Filed: 1988-08-05
Abstract: PURPOSE:To prevent an electric equipment from being damaged by over-. excitation by performing gate interruption of an excitation device by the output signal of an overexciting relay and that of a field circuit breaker trip incapability detection device. CONSTITUTION:When a generator 17 is stopped, a parallel circuit breaker 11 is opened in unloaded condition, and then a field circuit breaker is cut off. At this moment, the generator 17 is parallelled off from a system 11A. However, when a field circuit breaker 18 comes to be unable to trip, a main machine rotating speed 23 is reduced. Since an automatic voltage regulator 13 acts on so as to keep generator voltage 24 at a rated value 22 and corrects the reduced portion of voltage instantaneously, it causes excessive exciting current 25 to flow. An overexciting relay 16 inputs an AND signal of an operation signal and an output signal of a field circuit breaker trip incapability detection device 18A is inputted into the automatic voltage regulator 13 and performs gate interruption of an exciting rectifier 19. Abnormal rise of V/F value of the generator in the stopping control can thereby be prevented.

Title: Device for evaporating and concentrating waste photographic processing solution
Inventor: KUREMATSU MASAYUKI
IPC: G03D13/00
Filed: 1987-08-04
Abstract: PURPOSE:To reduce the odor generated during evaporation and concentration and to surely prevent the leakage of odor to the outside of the title device by providing a reheating means for reheating the vapor and gas generated by the evaporation and concentration. CONSTITUTION:The vapor and the gas evaporated from an evaporator are reheated by the reheating means 60, and the odorant is reduced. The vapor and gas with the reduced odorant is passed through a vapor discharge pipe 9, introduced into a heat exchanger 10 wherein the heat is exchanged with the waste photographic processing soln., and passed through a condensing means 11. Consequently, a part of the vapor is condensed to form a condensate. The condensate is passed along with the gas remaining in the vapor through a distillate inlet pipe 12, sent into a distillate tank 19, and discharged from the tip 12a under surface of the distillate. The condensed water is stored in the distillate tank 19. In this case, the gas discharged into the distillate ascends in the distillate performing a bubbling, thus to drive off the gas such as hydrogen sulfide dissolved in the distillate to the outside of the liq. The gas is continuously returned by the operation of an air pump 23 from the distillate tank 19 into the waste photographic processing soln. positioned at the lower part in the evaporator 1.

Title: Corner part machining method and device for cylindrical member
Inventor: FUJIO KOJI
IPC: B24B5/18
Filed: 1993-08-05
Abstract: PURPOSE:To reduce plant cost and maintenance cost by bringing a work of a cylindrical member into contact with a rotary brush while the work is rotated, moving the work in the axial direction, and chamfering the corner parts of the work into a specified curved shape by adjusting the depth of cut, and the contact time of the work with the rotary brush. CONSTITUTION:When the corner parts of a spool 4 having steps in the axial direction are chamfered into an elliptic shape, the spool (work) 4 is put between a rotary brush 10 rotated at about 2000 rpm and a rotation-adjusting wheel 20. Since the conveying path 33 of a blade 30 is a sloped path, the spool 4 flows downward on the sloped conveying path 33 of the blade 30, and is chamfered while it is moved slowly from the inlet side 31 to the downward outlet side 32. In this case, when the corner parts are chamfered into an elliptic shape, the minor axis is determined by adjusting the distance between the axes of the rotary brush 10 and the rotation-adjusting wheel 20, a depth of cut- adjusting mechanism 13 or 23, and the depth of cut D. The major axis is obtained by adjusting the feed speed of the work or the contact time of the work with the rotary brush 10.

Title: Current amplifier circuit
Inventor: MAEDA MASATOSHI
IPC: H03F3/30
Filed: 1994-07-27
Abstract: PURPOSE:To increase maximum output power without increasing the size of an output transistor by providing a second level shift means on a level shift loop circuit equalizing input voltage with output voltage. CONSTITUTION:Input voltage Vin is supplied to the input of an inverted Darlington circuit 1 via a first level shift means D 3. By providing a second level shift means D4 corresponding to the first level shift means D3 on a level shift loop circuit equalizing input voltage Vin with output voltage Vout, the base potential of the driving transistor of the inverted Darlington circuit can be made high even when the input voltage lowers down to the same potential as the ground potential of the circuit. As a result, because a saturation opeartion is hardly generated, the base current required for an NPN output transistor Q1 is sufficiently supplied and the transisitor Q1 an be operated in a saturation area, the amplitude of output voltage can be made large on the ground potential side of the circuit.

Abstract: PROBLEM TO BE SOLVED: To improve the operability of an image forming device/method by calculating the quantity of reference data according to the size and the mode of a source document and showing the number of sheets of processable source documents against the remaining memory capacity. SOLUTION: The quantity of reference compressed data are previously stored in the tables 94a and 94b of a nonvolatile random access memory NVM 94 according to the source document size and the source document mode proper to an image forming device or to the source document size that is registered by a user. A main CPU 91 selects a setting mode after deciding an input mode of the user and reads the quantity of compressed data corresponding to the source document size and mode out of the table 94 or 94b of the memory NVM 94. Then the CPU 91 calculates the number of sheets of source documents based on the memory remaining capacity and displays the guidance, for example, '20 sheets and 10 sheets readable at a time in character and photo modes respectively' at a display part 82a. Thus the user can roughly know the number of remaining sheets of source documents that can be sorted.  Furthermore, the user can update the storage contents of both tables 94a and 94b.

Title: Copying machine
Inventor: YOSHIUCHI KATSUHIRO
IPC: B41J11/66
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce dispersion of cut length by making a conveyance speed of resist rollers higher than the conveyance speed of rollers before transfer, extending over a fixed time, after a roll sheet reaches the rollers before transfer, during conveyance of the roll sheet. SOLUTION: When copying is begun, a roll sheet 4 drawn out from roll main bodies 4A-4C is primarily fed, and once stopped in the condition held with resist rollers LL. Thereafter, it is secondarily fed, and when the roll sheet 4 enters rollers before transfer TL, a conveyance speed of the resist rollers LL is made higher than the conveyance speed of the rollers before transfer TL. As a result, the roll sheet 4 conveyed between the resist rollers LL and the rollers before transfer TL is slackened so as to become a loop shape. Dispersion of tension is absorbed by this slackness. As a result, dispersion of tension applied to the roll sheet 4 has not so much influence on the roll sheet 4 of the upper stream side in the conveyance direction K of the resist rollers LL.

Then a specific detecting power DlambdaP* representing the photoelectric conversion characteristic of the element 1 can be determined by DlambdaP* (lambda/2.h.C).[(eta/phib).{2-(Rd H/Rd L)}]<1/2>. In this expression, lambda:a cutoff wavelength of the element 1, h: a Planck's constant, C: velocity of light, eta: quantum efficiency of the element 1, and phib: a background radiation flux under high-level background radiation. The wavelength lambda is determined by the element 1 and the quantum efficiency may be set at eta=1. Therefore a variable is a resistance value of the element 1 alone. By providing a criterion of Rd H/Rd L<=0.3, for instance, subsequently, the evaluation of the characteristic of the element 1 and the selection of the quality thereof can be performed by using the expression of the specific detecting power DELTAlambdaP*.
