Title: Roller bearing for rotary press
Inventor: URURITSUHI KUREEBAA
IPC: B41F13/28
Filed: 1989-02-17
Abstract: PURPOSE: To obtain a fine adjustment by forming an eccentric bushing in a special shape of a crack clamped at a side stand in a reciprocating slide crank, thereby remarkably reducing a rotating angle of an adjusting motion of the bushing to a rotation of a roller receiving member. CONSTITUTION: When an eccentric bushing 5 is rotated, for example, at 90 deg. to a left or right side, assembling and disassembling directions of a slit S of a bearing 20 and hence a roller 1 are slightly rotated at only a half of an angle α. This rotating angle is specified by a : b=α:2 by a ratio of an eccentricity (a) to an interval (b) between a central axis of the bearing hole of the bushing 5 and a knuckle joint 10. A rotation of the assembling or disassembling direction in the worst case occurs at the angle αby rotating the bushing 5 at 180 deg. leftward or rightward in a lateral direction. The roller 1 can be delicately adjusted to the roller 2 while suppressing a change in the assembling or disassembling direction of the roller 1 to a minimum limit.

Title: Flow rate controller for open waterway
Inventor: SAITO TAKESHI
IPC: G05D9/12
Filed: 1985-02-27
Abstract: PURPOSE:To shorten the flow-down delay time and to attain the stable control of flow rate by giving a big flow rate change until the change of the stored amount of water is corrected when flow rate is changed and then performing the normal control so that the inflow rate follows up to the outflow rate of water. CONSTITUTION:In a steady state, a subtractor 8 calculates the difference between the inflow amount QO of an open waterway detected by a detector 3 and the desired amount Qa detected by a detector 7. The control signal operated by a control part 9 is impressed to an opening amount control part 14. Then a valve 2 is controlled to keep a fixed level H of a control tank. When the change of the amount Qa exceeds a prescribed level, a stored amount arithmetic circuit 12 supplies the detected amount QO and the amount Qa to calculate the variation of the stored amount. Then the control signal is delivered to an adder/subtractor 13 to give said variation of the stored amount to the open waterway 4 for a short time. Then the valve 2 is controlled.

Abstract: PURPOSE:To surely prevent a burn-out failure of a stabilizer of the discharge lamp, by delaying to operate the other thermally operating element and partially fusing the circuit in an outer tube when one of the series-connected two thermally operating elements is in no operation. CONSTITUTION:When the auxiliary discharge between a main electrode 3a and an auxiliary electrode 10 continues for a prescribed length of time, a bimetal 6a of the first thermally operating element works to release the connection between a connecting lead 21 and movable contact 15' and shift the operation toward the main discharge between main electrodes 3a, 3b, subsequently the contacting state between a movable contact 16 and fixed connecting rod 13 of a bimetal 6b of the second thermally operating element connected in series to the bimetal 6a is opened. Here if the contact 15' and the lead 21 are welded, the bimetal 6b works to open the contact state between the contact 16 and a fixed connecting rod 14, generate a discharge between locations of the lead 21 and a filament 7 or filament fixing rod 22 and the like having a different potential finally fuse those parts. In consequence, the circuit in an outer tube 1 is partially disconnected to cease an electric current conduction, thus to surely prevent a burn-out failure of the stabilizer.

Filed: 1988-02-18
Abstract: PURPOSE:To reduce fluctuation of the upper set position of cut paper by providing slits for regulating the upper limit height automatically when a cut paper is fed and for reducing the table lift speed when papers are supplied or replaced. CONSTITUTION:When cut sheets 3 are fed continuously and the height of the sheets reaches to a lower limit B, a light shielding board 10 moves in the direction of an arrow to face a slit 11 with the optical path of a photo-interruptor 6, and the light emitted from a light emission element is received by a photoreceptor element to cause rotation of a motor 91 thus lifting a table 2. When a lever 4 is pushed up and the optical path of the interrupter 6 is shielded by the shielding board 10, the motor 91 is turned OFF to stop the table 2. When the table 2 is lowered farther than the lower limit in order to supply cut sheets 3 or to replace a cut sheet 3 having different shape, the optical path of the interrupter 6 faces with the slit 113 of the shielding board 10. When the cut sheets are mounted on the table 2 and the machine is operated, the optical path of the interrupter 6 is not shielded by the shielding board 10 and the motor 91 is turned ON to lift the table 2.

Title: Current limiting device for motor
Inventor: NARISAWA FUMIO
IPC: H02P29/00
Filed: 1980-03-25
Abstract: PURPOSE:To protect a motor from overloads by reducing the current at an input roll when the current at an output roll exceeds an upper limit value. CONSTITUTION:A transistor switch 13 is opened when the current value of a motor 6 for output roll 4 reaches 95% and a transistor switch 11 becomes control ON at 100% or more. In this method, as the current of the motor 6 is fed into a current limiting device 16 after the current of the motor 6 detected by a shunt 7 has been integrated by an integrator 12, the current of a motor 17 for input roll 2 decreases below a current reference Ri. As a result, the tension between the input and output rolls decreases to limit the current of the motor for output roll. The transistor switch 11 becomes control OFF when the current of the motor 6 for the output roll reaches 90% and the transistor switch 13 will be closed at 85% or less to make the output in the integrator 12 zero.
