Title: Extinction ratio compensating circuit
Inventor: IMAMURA KEIICHI
IPC: H01S5/068
Filed: 1992-01-11
Abstract: PURPOSE:To provide the title extinction ratio compensating circuit capable of holding the extinction ratio at a specific level. CONSTITUTION:A monitor photodiode PD is self-contained in a laser diode module so as to convert the photo-output from a laserdiode into a current. The peak value of AC component in an output current of the monitor photodiode PD is detected by a resistor R1 through a capacitor C2 while the voltage decline in another resistor R2 is smoothed by another capacitor C1 to generate a DC component. Next, both components are amplified to control a transistor Q3 by the differential voltage. When the extinction ratio declines, the DC component value is increased to boost the base potential (Vc) of the transistor Q3 resultantly increasing the modulation current thereby enabling the decline in extinction ratio to be compensated.

Title: Production of titanium clad thin steel sheet by using copper or copper alloy as intermediate joining material
Inventor: YAMAMOTO AKIO
IPC: B23K20/04
Filed: 1989-01-31
Abstract: PURPOSE:To easily obtain the titanium-clad thin steel sheet having excellent workability by subjecting the titanium-clad hot rolled steel sheet formed by inserting a metal contg. a specific ratio or above of copper between a base metal and a cladding material to cold working at a specific reduction ratio, then to annealing under specific conditions. CONSTITUTION:The Ti-clad hot rolled steel sheet formed by inserting the copper or the copper alloy contg. >=30% upper as the intermediate joining material between the base metal and the cladding metal is subjected to the cold working at >=10% and is then annealed for 0.2 to 10 minutes at 600 to 800 deg.C in the atm. or an atmosphere contg. >=2% O2. A long period of time is required for softening and the deep drawability after the recrystallization of both the base metal and the cladding metal is deteriorated if the annealing temp. is <600 deg.C. The coarse crystal grains of the base metal are formed and the deep drawability of the base metal is deteriorated if the annealing temp. is over 800 deg.C. The recrystallization is insufficient it the annealing time is <0.2 minute. The infiltration of oxygen into the Ti layer is so large that the bending workability is drastically deteriorated if the temp. is over 10 minutes. The good softening and recrystallization of the base metal do not arise if the cold working is <10%. In addition, the content of the copper in the copper alloy is specified to >=30% for the need of melting by diffusion solutionization with the Ti.

Abstract: PURPOSE: To quickly eliminate the abnormal output of an equipment by controlling an equipment model based on the control logic that is equal to a real control system to adjust the dynamic characteristic against occurrence of the abnormal output and then simulating the correction controlled variable to reflect it on the real control system. CONSTITUTION: When the idle rotational frequency of an engine, for example, is controlled, an equipment model 21B models the dynamic characteristic of an equipment based on the corresponding relation between the input value and the output value of a real device engine 21A.

Abstract: PURPOSE:To automatically making change-over between two-wheel drive and four wheel drive in both forward and backward directions of an automobile by changing over the engagement of an one-way clutch operating reversely when an inner wheel is moved with a change in the rotational direction of a propeller shaft. CONSTITUTION:When an automobile advances with front wheel drive and a right rotational drive force is transmitted to an input shaft 3, an inner wheel 6 is moved to the right end by the guide of a screw section 5 and abuts against a stopper surface 17 so that a clutch 9 moves to and engages with a cam surface 7 of the inner wheel 6. The rotation of a casing 1 is made higher than that of the input shaft 3 by the rear wheel rotated along with the front wheel, and the roller 14 of the clutch 9 is disengaged from an outer wheel 11 so that a drive force is not transmitted to the casing from the input shaft 3 and two-wheel drive is maintained. When the front wheel slips, the rotation of the input shaft 3 exceeds that of the casing 1 and the roller 14 is caught in a clutch cam surface 16 and the cam surface 7 to transmit the rotation of the input shaft 3 to the rear wheel so as to change-over the drive to four- wheel drive. When the front wheel slips in the retreating operation, the inner wheel 6 abuts against a stopper surface 18 so as to change over the drive to four-wheel drive.
