Title: Paper skew correcting device
Inventor: KAI HIDETAKA
IPC: B65H9/00
Filed: 1983-05-20
Abstract: PURPOSE:To enhance the function of correcting the skew of a paper, by providing such an arrangement that a conveying means on the side where the front end of the paper transferred in a skew condition at first reaches a gate is deenergized while the front end of the paper which comes in a delay is advanced. CONSTITUTION:When a sensor 4 detects the front end of the preceding side of a paper 9 which is transferred in a skew condition on a paper conveying path just before the paper 9 reaching a gate, a solenoid 5 on this preceding side is operated in accordance with a detection signal from the sensor 4 to lift up a slip roll 6 from a drive roll and as well a clutch for the drive roll is disengaged to release the nip force of the slip roll 6 so that conveying force for the preceding side is eliminated to damp a shock upon touching between the front end of the preceding side of the paper 9 and the gate, thereby the damage of the paper is remarkably reduced. During this stage, the front end of the retarding side of the paper is turned to the direction of the arrow B under conveying force by the slip roll 6 and a drive roll to correct the skew of the paper 9.

CONSTITUTION:The outer diameter of a roll of sheet 1 which undergoes a gathering process is measured, and whether the measurement result belongs to a A range or B range which are prescribed is determined by an outer diameter range determining means 52. The information from the determining means 52 is sent as signal S1 to a motor 25 through a phase change commanding means 51 by a signal S2, so that the motor 25 rotates a supporting disc 21 which supports the roll 1 by a necessary angle in a prescribed direction in order to displace relative positions of a plurality of moving pieces 23 provided on the supporting disc 21 with respect to the supporting spoke 31 by a necessary distance. Then the spoke 31 is inserted inside of a projecting part 2a of an enveloping paper 2, and at the time of opening by the inner diameter of the projecting part 2a, an tip end 31a of the spoke 31 is positioned nearly at the middle among moving locuses of the respective moving pieces 23. In this instance, the adjustment of the relative phase is not limited to two-staged adjustment, but an adjustment of an arbitrary number of stages or a stageless adjustment is also available.

Title: Exhaust gas purifier for diesel engine
Inventor: NOMOTO YOSHITAKA
IPC: F01N3/02
Filed: 1982-05-25
Abstract: PURPOSE:To completely burn fuel discharged into a burning cylinder when the operation of a burner is stopped, by continuing the operation of the burner when the temperature in the burning cylinder is not higher than a prescribed level and by stopping the operation when the temperature has become high. CONSTITUTION:When the temperature in a burning cylinder is not higher than a prescribed level, the output signal of a flip-flop circuit 27 has a high level due to the action of a control means 25 so that a drive circuit 23 keeps acting, despite the clogging of a filter 3 is eliminated. As a result, a burner 4 continues to operate, due to the action of pumps 14, 17 and the turn-on of a switch 18. When the temperature in the burning cylinder has become higher than the prescribed level because of the continued operation of the burner 4, the output signal of the flip-flop circuit 27 changes into a low level so that the burner stops operation.

Title: Current switch circuit for d/a converter
Inventor: YAN JIEN SAN
IPC: H03K17/16
Filed: 1994-04-27
Abstract: PURPOSE:To reduce the overshoot and undershoot amplitudes by changing the potentials applied to the gates by a gate switching circuit and controlling the logical level of the digital voltage. CONSTITUTION:The transfer gate transistors TR 14, 12, 18 and 16 are put between a logical level binary input signal line 6 and the gate terminals of p-channel MOS current control TR 26 and 28 respectively. Thus a current switch 10 functions to prevent a case where the gates of both TR 26 and 28 receive the signals of high logical levels. These gates have high impedances and the gate terminals of the TR 26 and 28 are protected from the full logical amplitude level signals. Therefore the levels of voltage applied to the gate terminals of both TR 26 and 28 are limited at the value between both reference voltage levels 8 and 9. These reference voltage are set at such levels that can reduce the change of voltage applied to both TR 26 and 28.

Abstract: PURPOSE: To improve the durability by properly shifting the overlapping parts of a lined flexible woven material pasted in multilayers for the weir designed to stop water with the erection of an expanded bag body made of the flexible membrane.  
     CONSTITUTION: The water stopping weir made of a flexible membrane bag body is installed transversing the river. A fluid, for example, either air or water or both thereof is fed into the bag so that it is expanded and erected to stop water. Several sheets of lined flexible woven material such as rubber-lined cloth are pasted together to form the bag. In this case, for example, when the material is pasted in two layers, the overlapping parts 8 and 8' of the second layer of the rubber-lined cloths 6W6" are arranged at the center between the overlapping parts 7 and 7' on the first layer of the rubber-lined cloths 5W5". This prevents breakage of the bag regardless of separation of any one overlapping part.
