Title: Semiconductor photodetector
Inventor: MUROTANI TOSHIO
IPC: H01L31/10
Filed: 1988-03-04
Abstract: PURPOSE:To improve sensitivity and make high speed responsibility as well as high frequency characteristics superior, by mounting a lens which condenses signal rays of incident light on a photodetecting part and forming an area projected by the lens at a right angle to the forward direction of the above signal rays so that its area is larger than that of the photodetecting part. CONSTITUTION:A window part 9 is provided on the rear of an n-type InP substrate 1 and a lens 10 is mounted at the window part 9. A reverse bias voltage is impressed between a p-type electrode 7 and an n-type electrode 8; then, in a state that a depletion layer is formed at a pn junction photodetecting part between an n-type InGaAs layer 3 and a p-type diffusion region 5, for example, when signal rays of light are incident upon the lens 10 through an optical fiber, they are condensed to the window part 9 after being refracted as shown by alternate long and short dash lines. Then, the rays having an energy that is a band gap or less of InP penetrate through the n-type InP substrate 1 as well as an n-type InP buffer layer 2 and are absorbed in the depletion layer of the n-type InGaAs layer 3 and, then, the above mechanism operates as a photodetector. As the signal rays of light which are incident upon the above photodetector are condensed on a small scale by the lens 10, the size of a pn junction part which acts as a photodetecting part can be formed in such a way that it becomes smaller to about a fraction of those of conventional ones. Thus, junction capacitance decreases and CR time-constant response speed increases.

Title: Telephoto lens system
Inventor: YASUKUNI MITSUO
IPC: G02B13/02
Filed: 1981-04-06
Abstract: PURPOSE: To achieve short-distance focusing, to suppress aberration variation, and to realize compact structure, by enabling a lens component in the rear group of a lens system to move finely in the direction of the optical axis.  
     CONSTITUTION: This lens system consists of a front groupIwhich has positive composite refracting power and a rear group II which has negative composite refracting power. Then, rear group is divided into the 1st positive component (II-1), the 2nd negative component (II-2), and the 3rd positve component (II-3) successively from an object side, and the 2nd element (II-2) is movable to an image side. In this case, inequalities hold, where F 1 , II-1, and II-2 are the composite focal lengths of the 1st components of the front and rear groups, and the 2nd component of the rear group during infinite-distance focusing. Further, D is an axial distance from the side surface of the front group closest to an object to the side surface of the rear group closest to the object, and while F 1  is the composite focal length of the front group, (f) is that of the whole system. Thus, sufficient short-distance focusing is achieved by finely moving the lens component in the rear group of the lens system in the direction of the optical axis.

Abstract: PROBLEM TO BE SOLVED: To drive a lens whenever a command means is depressed, regardless of the presence of a state where the drive of the lens is inhibited by providing the command means for commanding only the operation of preparing for photographing, in accordance with the depression degree of a shutter button, regardless of the states of the shutter button and a selecting means. SOLUTION: When respective focusing buttons 5 and 11 are depressed regardless of the setting of a selector 7 and a locking switch 10, the distance ring of the lens 2 is driven by a specific amount corresponding to a measured nonfocusing amount, during the depression. When the locking switch 10 is in an inhibitory state, operation by a V-shutter button 9 is not executed, but a focusing operation by the V-focusing button 11 is permitted. When the selector 7 is set in a normal position, the operation of the distance ring is executed by the half-depression of the respective shutter buttons 4 and 9. When the selector 7 is set in an inhibition position, switching to a mode not for operating the distance ring of the lens 2 by the respective shutter buttons 4 and 9 is attained.

Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a substrate and the sticking of the substrate to a other substrate due to grain growth at the time of firing, the reduction of dielectric breakdown voltage and the increase of unevenness in capacitance. SOLUTION: This compsn. consists of (Ba1- Q- XCaQSrX)A(Ti1- Y- ZZrYSnZ)O( A+2) (where 0.04<=Q<=0.08, 0<=X<=0.02, 0.015<=Y<=0.03, 0.035<=Z<=0.07 and 1<A<=1.02) as the principal component and one or more kinds of subsidiary components selected from among SiO2 , Al2 O3 , ZnO, B2 O3 , WO3 , kaolin and MnO. The amt. of the subsidiary components is 0.05-2wt.% of the amt. of the principal component.

Abstract: PROBLEM TO BE SOLVED: To improve ignitibility in a spark plug having plural earth electrodes, particularly, ignitibility at low temperature starting time and to a lean air-fuel mixture. SOLUTION: In a spark plug 1 to form a spark gap 11 by a tip surface 6 of a central electrode 3 and tip inside surfaces 16 of earth electrodes 9 and 9 whose tip surfaces 10 and 10 are opposed to each other, a distance S of a clearance formed of the tip surfaces 10 and 10 of the mutually opposing earth electrodes 9 and 9, is set to 0.3 to 1.5mm, and the tip inside surfaces 16 of the earth electrodes 9 and 9 are arranged in parallel to the tip surface 6 of the central electrode 3.
