Filed: 1992-05-13
Abstract: PURPOSE:To surely prevent the oscillation of a control loop by varying the loop gain of the control loop of a servo control system or a movement control system and setting it to the stable loop gain by which the control loop is stabilized. CONSTITUTION:When a focus control loop is closed, by a microcomputer 14, the output of a compensation controller 13 is monitored by an A/D converter 15.

Title: Hydraulic buffer
Inventor: SUZUKI TAKUROU
IPC: F16F9/06
Filed: 1983-08-10
Abstract: PURPOSE:To restrain change in buffer performance by discharging surplus working oil to the outside of an oil seal. CONSTITUTION:When the depression of a free piston 19 reaches a predetermined value, an end of an adjusting rod 22 gets out of an O-ring 25 so that working oil in an inner tube 12 flows from between an escape hole 24 and the adjusting rod 22 to the O1 side for adjustment. Since the volume of a gas chamber G is expanded, the end of the adjusting rod 23 fits again into the O-ring to maintain the sealing property of the inner tube 12. By this adjusting function can be prevented excessive increase of pressure in the gas chamber G of a hydraulic buffer.

Title: Semiconductor laser device
Inventor: IIO SHINJI
IPC: H01S5/00
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain a highly accurate oscillation wavelength only with a small quantity of its discrepancy in a semiconductor laser device, by providing the driving circuit for so driving its control element portion that the sum of the respective heat generation quantities of its light emitting element portion and its control element portion is held always in a predetermined value. SOLUTION: Increasing by a driving circuit the current to be injected into a control element portion 12 when changing the injection current of light emitting element portion 11 into a predetermined current, the sum of the respective heat generation quantities of these two element portions 11, 12 is always kept constant. The simplest method for this purpose is such a driving method that the sum of the respective injection currents of the light emitting element portion 11 and the control element portion 12 is made constant. However, since the structures of these two element portions 11, 12 are different from each other, it is actually necessary for the highly accurate compensation of the above control that the oscillation wavelength of a semiconductor laser device is monitored to set the current value of the control element portion 12.  As a result, the semiconductor laser device having a highly accurate oscillation wavelength only with a small quantity of its discrepancy even in the case of an optical intensity modulation is obtained.

Filed: 1984-07-17
Abstract: PURPOSE:To release pressure contacting state between the paper feed roller and paper in an automatic paper feeder for printer by constructing such that the separation click can be pushed down. CONSTITUTION:Upon rotation of the paper feed roller shaft 2 counterclockwise through rotation of platen shaft not shown, sleeves 30, 31 will rotate to rotate a cam 32 counterclockwise because of the winding direction of a spring clutch 33 thereby the end of cam 32a will push down a separation click 7 together with a paper 5 thus to colloide a lever 33a against a stopper 37 and stop. Under this state, the paper 5 is separated from the paper feed roller 1. Upon rotation of the paper feed roller 1 clockwise through reverse rotation of the platen shaft, each section will function reversely to pressure contact the paper feed roller 1 and the paper 5. With such arrangement, the pressure contact/release mechanism between the paper feed roller and the paper can be simplified.
