Title: Electronic image pickup device
Inventor: FUJII NAOKI
IPC: H04N5/369
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To provide an electronic image pickup device where power of an aperture and/or shutter drive source is saved during the operation of an image pickup element. SOLUTION: In the case of starting photographing by this electronic image pickup device, a self-hold type aperture drive source is driven by pulses and it is held in an aperture stop state and a CCD shutter is turned on and exposure is started. In relation to the end of exposure, a solenoid of a mechanical shutter drive source is driven by a 1st voltage V1 to close a mechanical shutter. Then the voltage applied to the solenoid is decreased to a lower 2nd voltage V2 to hold the shutter closing state. Signal charges of a CCD are transferred during the shutter closing state. After the end of transfer, the solenoid voltage is turned off, the aperture drive source is driven by pulses and it is restored to an aperture open state and then the photographing is finished.

Abstract: PROBLEM TO BE SOLVED: To provide a stabilizer bush with a favorable spring characteristic and durability which can prevent the generation of an abnormal sound and a lateral shift and also without the fear of cost increase by the increase of the number of parts. SOLUTION: In a stabrlizer bush for inserting and holding a stabilizer bar in the cylinder of a rubber elastic body 1 molded cylindrically and holding its outer periphery surface by a bracket installed on a vehicular body, the rubber elastic body 1 is composed of a cylindrical base body rubber 2 and the cylindrical high slidable rubber 3 of an inner periphery part. As the inner periphery part for holding the stabilizer bar is constituted by the high slidable rubber 3, a slide restrained is reduced and the generation of the abnormal sound is restrained. As the base body rubber 2 contacted to the bracket is constituted by an usual rubber maternal, the friction resistance to the bracket is big and the lateral shift is hardly generated.

Abstract: PURPOSE:To eliminate a defect of a picture element even when a hole is made in a silicon oxide layer and to enhance a yield by a method wherein an interlayer insulating layer for auxiliary-capacitor formation use is formed of an anodized layer of tantalum nitride in which the mole ratio of Ta/N for the tantalum nitride is a prescribed value or lower. CONSTITUTION:An auxiliary capacitor Cs is constituted of the following: an interconnection 1 for auxiliary-capacitor formation use on a glass substrate 4 whose surface is anodized TaN; a silicon oxide layer 3 laminated so as to cover an anodized layer 2; and ITO 5 constituted on the silicon oxide layer 3. The auxiliary capacitor Cs is formed between the interconnection 1 and the ITO 5. The interconnection 1 for auxiliary-capacitor formation use is formed of TaN as its material TaN is patterned; after that, an anodic oxidation treatment is executed; the anodized layer of TaN is formed. The mole ratio of Ta/N for the anodized layer of TaN is 2 or lower. The reason is as follows: when the mole ratio of Ta/N for tantalum nitride exceeds 2, a leakage current becomes large in the anodized layer of tantalum nitride. Consequently, it is preferable that the mole ratio of Ta/N is 2 or lower.
