Patent JP-H05150577-A (JP)
Title: Image forming device
Inventor: ONO KAZURO
IPC: G03G21/00
Filed: 1991-11-27
Abstract: PURPOSE:To prevent a rear end trim from being soiled with toner by preventing the rear end of a sheet material from turning up. CONSTITUTION:The sheet material P is held and carried between the photosensitive drum 1 and the transfer roller 6. A bias power source 26 is connected to the transfer roller 6 and, addition, an adjusting means for changing the time of switching at which a transfer bias voltage at the transfer time is switched to a weak bias voltage at the nontransfer time is connected thereto. When the sheet material P is supplied to the photosensitive drum 1, back torque differs depending on whether the sheet is fed from a sheet feeding roller 17 (at the time copying on the first side) or from a sheet refeeding roller (at the time of copying on the second side), and the first side and second side differ from each other in speed V1 at which the sheet material P is carried. Because of difference, when the time of switching is the same, the rear end turns up at the time of copying on the first side. When the first side of the sheet material is detected by a front/back detecting means, the time of switching is made early, thereby preventing the rear end from turning up. When it detects the second side of the sheet material, the time of switching is made late, thereby preventing the transfer defect of the rear end.

IPC: G02B6/28
Filed: 1989-12-25
Abstract: PURPOSE:To allow the uniform control of tension so that stable distribution characteristics are obtd. by inserting and fixing the parts, from the respective coating parts to parts to be removed of the coverings, of incident/exit side optical fiber groups into a capillary, then welding and stretching both fiber groups and fixing the fiber groups to a housing member. CONSTITUTION:After the bare optical fibers 1', 2' are inserted into the fine hole 3 of the capillary 4, the capillary 4 is positioned to the point from the coating parts 5, 6 to the parts to be removed of the coverings of the optical fibers 1, 2 and is fixed thereto by an adhesive agent. The front ends 8, 8 and 9, 9 of the optical fibers 1 are brought into contact after the axial alignment of the optical fibers 1, 2, and thereafter, the ends are heated, welded and connected. While the tension is applied around the welded part 10, the welded part is heated and is stretched under monitoring of a branching ratio, by which a desired branching ratio is obtd. The welded part is fixed into the housing member 11 consisting of ceramics, etc., and is thereby finished. The control of the tension on the optical fibers is stabilized in this way and the uniform twist is attained. The stable branching ratio is thus obtd.

Filed: 1990-11-30
Abstract: PURPOSE:To supply necessary optimum refrigerant amount by comparing a temperature measured by a temperature sensor provided in an exit/entrance section of a plurality of refrigerant circuits with a saturated temperature, equalizing the states at the outlets of the circuits, and so controlling the openings of expansion units as to become optimum states. CONSTITUTION:Temperatures of outlets of refrigerant circuits 102a-102c are respectively measured by temperature sensors 5a-1-5c-1, sent as signals to a controller 6, and the temperatures are compared with an evaporating temperature. If the temperatures are equal to the evaporating temperature, expansion units 2a-2c are controlled to be closed, while if the temperatures are higher than the evaporating temperature, the units 2a-2c are controlled to be opened. The outlets of the circuits are regulated to the state of saturated vapor, and hence the states of the outlets of the circuits are controlled to be equalized, and the circuits are controlled to be supplied by necessary optimum refrigerant amounts, thereby drawing the capacity of a heat exchanger to a maximum limit.

IPC: H04B1/10
Filed: 1991-12-20
Abstract: PURPOSE:To enable speedy tuning to the same network station when a multipass is generated while receiving 4 radio broadcasting in a radio data system(RDS). CONSTITUTION:An identification signal RDSID outputted from a signal decoder 12 is turned to a low level while receiving the broadcasting in the RDS and turned to a high level while receiving any broadcasting not in the RDS. Therefore, a processing circuit 14 counts the number of times when the identification signal RDSID is turned to the high level per a cycle W previously decided while receiving the broadcasting in the RDS and when a count value P1 is larger than a value P decided in advance, the most significant broadcasting station of a tuning list preparing channels in the order of high received electric field intensity is tuned. Thus, the generation of the multipass is speedily detected from the identification signal RDSID and tuning can be automatically executed while always following up the broadcasting station in a satisfactory receiving state among the broadcasting stations broadcasting the same contents.

Title: Returning method of lip's turn-up of seal and seal inserting device
Inventor: HIRAMATSU MOTOI
IPC: B23P19/02
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a method capable of easily returning a turn-up of a lip of a seal to the original state even when the lip is turned up on putting the seal on a shaft. SOLUTION: A D cut part 14C is provided at the tip part of the shaft body 14B of circular cross section of a shaft 14. When a seal 10 having a lip 10A' is put on the shaft 14, the lip 10A' is turned up like a 10A" in the figure. In this case, when the seal 10 is positioned at the D cut part 14C, the shaft 14 and the seal 10 are rotated relatively. Then, as they are rotated, the turn-up is returned to the original state, and the turn-up is completely eliminated at the time when the shaft 14 and the seal 10 make one revolution. Thereafter, the seal 10 in which the turn-up is returned to the original state, is put on the shaft body 14. In this case, when the seal 10 is put on the shaft 14 while they are rotated relatively, the seal is prevented from being turned up due to steps on the shaft.

Filed: 1994-12-27
Abstract: PURPOSE: To accurately read a recording pattern recorded in a medium at all times by comparing a read pattern with a stored reference pattern and correcting the reference pattern based on the compared result. CONSTITUTION: At the time of reading a bar code which is the read pattern, the standard value of the respective bar code measures of different widths is stored in a RAM 23 beforehand in terms of the specifications of a bankbook 13 to be utilized for transactions and a CPU 21 compares a detected bar code detection measure with the standard value at the time of detecting the bar code. When a detection error is present in the compared result, the feedback amount of a threshold level is calculated corresponding to the size of the detection error. So as to reflect the feedback amount on the threshold level, level change is performed, read is performed and a threshold level side to be the read reference is corrected. Thus, the bar code recorded in the medium is accurately read.
