Title: Current source circuit
Inventor: NANBU HIROAKI
IPC: H03F3/343
Filed: 1994-08-25
Abstract: PURPOSE: To lower the source voltage of the current source circuit which is made small in the temperature dependency and source voltage dependency of a current value. CONSTITUTION: A start-up circuit SU which turns ON when the voltage difference between a source voltage VEE and a ground voltage reaches a specific voltage to supply a current and reaches high impedance when transistors(TR) Q2 and Q3 turn ON as a result and then TRs Q1 and QCS turn ON is connected to the bases of the Q2 and Q3. A current source I1 uses a current which flows when the Q2 turns ON. One end of a resistance RE is connected directly to the VEE and the other end is connected to the ground voltage through a high- impedance circuit (QCS, Q3, and I1) and also connected to the VEE thorugh a low-impedance circuit (QCS, Q3, Q2, R2, and Q1). The ratio of emitter current density of the Q1, Q2, Q3, and QCS is set to 1:1:1/20:1.

Title: Interferometer and manufacture and sensing method thereof
Inventor: KENESU EI FUESURAA
IPC: G02F1/35
Filed: 1991-08-09
Abstract: PURPOSE: To obtain an interferometer capable of operating without instability of source characteristics or without other remarkable deterioration. CONSTITUTION: An improved sagnac interferometer has a wide band light source 100 including fluorescent light medium, which is pumped by the light from a pumping source with sufficient intensity to temporarily generate incoherent light by superfluorescence. For example, superfluorescent light medium has an optical fiber 130 pumped in a reverse direction. The optical signal input to the sensing loop 142 of the interferometer is amplified by a modulator, output from an interferometer loop 142 and amplified by the optical gain of a superfluorescent fiber operated as the source 1000 and an amplifier. This is selected so that a modulation frequency is substantially reduced in the depth of the modulation gain to avoid the gain modulation in the superfluorescent fiber 130.

Title: Suspension controller for vehicle
Inventor: KAWABATA KAZUNOBU
IPC: B60G17/015
Filed: 1985-09-11
Abstract: PURPOSE:To prevent the nose dive by obtaining the variation standard value from the average value of the attitude variation and controlling the suspension characteristic when the detected attitude variation exceedes a standard value by a prescribed value or more in brake application, in a suspension device having the variable damping force and spring constant. CONSTITUTION:When each detection signal of a ground clearance detector 4 and a brake switch 32 is input into a controller 5, the signal of the brake switch 32 judges the brake application state of a car. While, the input variation quantity of car height 4 is calculated, and the attitude variation standard value is set from the average value in a long time. Each detected attitude variation quantity is compared with the set attitude variation standard quantity, and when the variation quantity for the standard value of the detected variation quantity is over a prescribed value, the variation of attitude is suppressed by damping-force-controlling the buffer devices 2a-2d. With such constitution, the nose dive is prevented.

Title: Automatic focus matching device
Inventor: KOJIMA ICHIRO
IPC: H04N5/232
Filed: 1985-09-11
Abstract: PURPOSE:To exactly apply amplitude modulation to a high frequency component of a video signal obtained from a solid-state image pickup element and to improve a focusing accuracy by oscillating the solid-state image pickup element by a reference frequency. CONSTITUTION:A solid-state image pickup element is oscillated by a fine adjustment device connected to the solid-state image pickup element to generate a shading on a photodetective surface of the solid-state image pickup element. Namely, the solid-state image pickup element 22 is oscillated by a reference frequency by the fine adjustment device 33 directly connected to the element and an object picture an image of which is formed on the photodetective surface of the solid-state image pickup element 22 is periodically and optically shaded. Accordingly, a high frequency component included in an output signal of the solid-state image pickup element 22 is modulated in its amplitude. The solid-state image pickup element 22 is smaller and lighter than a lens. Since an inertia of an oscillating system including the fine adjustment device 33 is extremely small, the oscillating system scarcely generates a delay with respect to a reference frequency signal inputted to the fine adjustment device 33 and a stability of a closed loop is improved.

Abstract: PURPOSE:To prolong a service life of a fixing roll and to secure a good fixing quality without making warming up time long by making a set temperature to be a temperature where toner is thermally deformed by heat and making a specified time of passage after connecting of power source to be up to a point when a lower limit for temperature where fixing can be carried out under standard fixing condition is reached. CONSTITUTION:When the power source is applied, a heater lamp 105 is lit, surface temperature of a fixing roll 103 is detected by a thermister 109 and whether it is above the specified temperature T1 of not is judged, and at the same time, the operation of a timer is started. Then, if it is below the specified temperature T1, the lighting of a heater lamp 105 is continued during a set time t1 of the timer. Here, the specified temperature T1 is above the temperature where the toner is deformed by heat, which is 110 deg., and the set time t1 is the time until the lower limit for temperature where fixing can be carried out under standard fixing conditions is reached. Thus, since the heat roll is rotated after the toner is softened, the warming up time is kept to a minimum, the service life of the fixing roll is prolonged, and the good fixing quality can be secured.
