Title: Electronic still camera
Inventor: TAKAYAMA TSUTOMU
IPC: H04N9/73
Filed: 1990-08-08
Abstract: PURPOSE:To automatically operate an accurate white balance adjustment without a color measuring circuit by operating a pre-exposure before operating a main exposure, integrating a color signal at that time to fetch it, and operating the white balance adjustment based on this value. CONSTITUTION:This camera is equipped with an image pickup means which converts copied body lights into electric signals and outputs plural chrominance signals, and a gain controlling means which controls the outputs of the plural chrominance signals and operates the white balance adjustment. Then, this device is equipped with integration circuits 10a-10e which integrates the chrominance signals, and an arithmetic controlling part 7 which judges the color of a light source, controls the gain control means, and operates the appropriate white balance adjustment by subtracting an integrated value obtained by the integration circuits 10a-10c when the image pickup means is preliminarily shielded and drived. Thus, the appropriate white balance adjustment can be automatically operated without the independent color measuring circuit of an outboard type.

Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a closure device for automoble trunk lid, capable of maintaining the rigidity of a lock base high, and miniaturizing a lock mechanism and reducing its weight. SOLUTION: While observing that the tip side of a part 48 being engaged with a striker 45, which precedes to enter a striker-entering groove, oscillates across the groove width in the striker entering groove, the tip side of the part 48 being engaged of the striker 5 is allowed to be narrower across the groove- width than the base side so that the part 48 being engaged of the striker 45 is not in contact with the groove side edge of the striker-entering groove. The groove width of the striker-entering groove should not be enlarged by an amount equivalent to the deflection of the tip side of the part 48 being engaged of the striker.

Title: Twist setting method
Inventor: YAHASHI YASUO
IPC: D01H13/08
Filed: 1983-11-08
Abstract: PURPOSE:To enable the uniform twist-setting of a polyester fiber yarn, by wrapping a twist-setting cylinder with a corrugated board which buckles under a specific plane compression stress. CONSTITUTION:A corrugated board which buckles under a plane compression stress of 1.5-3.0kg/cm<2> is wrapped around the cylinder barrel 4. A polyester fiber yarn having twist torque is wound around the covered cylinder in layers, and subjected to the twist setting. The corrugated board endures the stress caused by the winding of the twist yarn, and the buckling of the board takes place by the thermal shrinkage stress developed by the twist setting. The shrinkage of 3-5% can be absorbed by using a corrugated board 3 of 1.4-2.2mm. thick.

Title: Plane type light emitter
Inventor: YAGI HIROYUKI
IPC: H01J31/12
Filed: 1992-08-05
Abstract: PURPOSE:To nearly prevent fluctuation in luminance by changing a voltage distribution state between an electrode of a first back electrode and an electrode of a second back electrode on the basis of a voltage value of the second back electrode, and changing a diffusion state in the lateral direction of an electron emitted from a linear cathode. CONSTITUTION:A sinusoidal voltage of e.g. 0-20V in voltage and 100kHz in frequency is applied to an electrode 11a of a first back electrode 11 via a terminal 11b. In this plane type light emitter, a change of a voltage distribution formed between the electrode 11a of the electrode 11 and the electrode 12a of another electrode 12 causes a diffusion state in the lateral direction of an electron emitted from a linear cathode 7 to be changed. Namely, when a low voltage near 0V is applied to the electrode 12a, the electron emitted from the linear cathode is nearly dispersed in the lateral direction so that luminance near the linear cathode 7 is increased in a phosphor 4. When a positive high voltage near 20V is applied to the electrode 12a, luminance of the phosphor 4 where the electron is collected becomes high. Light is uniformly emitted with continuously repeated application of the voltage.

Title: Loop gain adjusting circuit of tracking servo circuit
Inventor: ONISHI KEIICHI
IPC: G11B7/09
Filed: 1984-10-05
Abstract: PURPOSE:To automatically adjust the volume of a loop gain properly against an external disturbance and to obtain a stableness of tracking, by identifying the disturbance according to the variance of an average value of tracking error signals and information signals which occur against the external disturbance. CONSTITUTION:The current which corresponds with intensity of light received by B, C parts of photodetector 12 through a lens 11 is added t amplifiers 21, 22, and 23, and forms a information signal 27 recorded on the disc. The average value of the envelope of the information signal is detected 24, and according to the output and the delayed 25 output, a hysteresis comparator 26 detects the external disturbance. Due to the existence of this disturbance, the tracking error signal is increased, and the comparator 26 outputs the detection signal only when the output of the detector 24 is the average value of the envelope of information signal and the average of the lost part is smaller than other average values. And, by the increase of the tracking error signal a level detector 19 issues detection signal, and a selection circuit 20 keeps a variable loop filter 17 at the loop gain of normal reproduction.

Patent JP-H1148932-A (JP)
Title: Brake device
Inventor: SUZUKI MASAKUNI
IPC: B60T8/48
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To suppress an increase/decrease of discharge pressure of a pump by including a booster device connecting an accumulator device with either one of a part between a flow control valve and brake cylinder of a flow passage and a discharge passage connecting the flow passage and the discharge side of the pump. SOLUTION: In a brake cylinder 20, a pump 62 is shared by an effective characteristic controller and an anti-lock controller and pressure is intensified by the pump 62, regardless of during the effective characteristic control or during the anti-lock control. Because the pump 62 alternately repeats a suction stroke and a discharge stroke and intermittently discharges hydraulic liquid, discharge pressure of the pump 62 originally pulsates. But an increase/decrease of discharge pressure of the pump 62 is suppressed and pulsation of discharge pressure of the pump 62 is reduced by elasticity of a spring in an accumulator 120 because the accumulator 120 is connected with the discharge side of the pump 62. As a result, a hydraulic pressure change in the brake cylinder 20 during the effective characteristic control and during the anti-lock control becomes smooth.
