Title: Optical axis inclination adjusting method of plural optical elements
Inventor: HARA YASUHIKO
IPC: G01B11/26
Filed: 1983-04-04
Abstract: PURPOSE:To adjust with high accuracy and quickly the inclination of an optical axis of a lens whose focal distance is short and also whose length is short, by forming plural laser light images formed by reflection of a laser light which is made incident to an optical system formed by plural optical elements. CONSTITUTION:By a translucent mirror 6, laser light 1 is made incident to a lens system 2 for detecting the inclination of an optical axis. Formed light spots P1, P2 are magnified by an objective lens 7, so that an image is formed and observed at a position of an eyepiece 8. As for the lights emitted from the objective lens 7, since the positions of P1 and P2 are different, both of them do not form an image at the same position of the eyepiece 8. The light is divided into two by a translucent mirror 9. A lens 9 is provided on one side of optical paths divided into two, so that both the two light spots P1, P2 form an image at an eyepiece position. In this way, when the inclination of the lens 2 is adjusted so that the two observed light spots P1, P2 are overlapped to each other, the advancing direction of the laser light can be made to coincide with the optical axis of the lens 2.

Filed: 1992-03-16
Abstract: PURPOSE:To facilitate the design of the peripheral circuit by providing a gain control signal output circuit and converting a gain control signal into a gain control signal changed in a range always smaller or larger than a reference input signal. CONSTITUTION:A gain control signal output circuit CNT is operated similarly as a usual inverter circuit and receives a gain control signal VCNT changed over a wide range and converts it into a gain control signal VCNTb changed below a reference voltage VREF. Since the variable range of the VCNTb is limited below the VREF in the variable gain amplifier section GCAb, the variable gain control characteristic decreasing monotonously is obtained. Furthermore, the VCNT is changed into the VCNTb changed over the VREF to obtain the variable gain control characteristic increasing monotonously and then the design of the peripheral circuit is facilitated.

Abstract: PURPOSE:To inhibit stress concentration effectively by forming a high impurity concentration layer and a thick element-isolation insulating film in an element isolation region in the horizontal direction and shaping only a high impurity- concentration layer in another element isolation region. CONSTITUTION:A plurality of N-type layers 2 constituting a photodiode are arranged and formed, and N-type layers 3 organizing channels for a vertical CCD are shaped along the vertical arrangement of the N-type layers 2. The peripheries of each N-type layer 2 are used as element isolation regions with the exception of transfer sections 4 transferring signal charges to the CCD channels. Sections isolating picture elements in the horizontal direction in the element isolation regions are composed of P<+> type layers 5 and thick element- isolation insulating films 7 shaped onto the layers 5, and sections except said sections are formed only of the P<+> type layers 5. Accordingly, even when the N-type layers 2 are miniaturized and the density of picture elements is increased, stress hardly concentrates, thus preventing the augmentation of leakage currents due to the generation of a defect, then improving the quality of a picture.
