Patent JP-H01295246-A (JP)
Title: Optical system provided with optical path folding means
Inventor: KOYAMA TAKASHI
IPC: G03B19/12
Filed: 1988-05-23
Abstract: PURPOSE:To thin and miniaturize an entire camera by turning a final reflecting mirror among plural reflecting mirrors arranged behind a photographic lens centering around a specified axis so that the switching of a photographing system and a finder system can be performed and making the common optical path of the photographing system and the finder system longer and larger. CONSTITUTION:Plural reflecting mirrors, for example, 1st-4th reflecting mirrors M1-M4, are arranged behind the photographic lens 11. After luminous flux L from the photographic lens 11 is reflected by the 1st reflecting mirror M1 in a direction orthogonal to an optical axis S1, it is reflected by the 2nd reflecting mirror M2 in a direction opposite to a photosensitive surface 13 so as to form the finder image (b) of an object (a) on the surface of a focusing plate 16. The finder system is so constituted that luminous flux from the finder image is condensed by a condenser lens 17, reflected by the 3rd reflecting mirror M3 in the direction orthogonal to the optical axis S1 and reflected by the 4th reflecting mirror M4 in a direction nearly parallel with the optical axis S1 of the photographic lens 11, then conducted to an eyepiece lens 18 through an eyepiece shutter 19. Thus, the entire camera can be easily thinned and miniaturized.

Title: Field effect transistor
Inventor: HONMA AKIRA
IPC: H01L29/808
Filed: 1980-09-13
Abstract: PURPOSE:To obtain a field effect transistor having strong reverse voltage breakdown resistance by forming the shape of a drain or source region to project toward the gate direction as the region becomes deep. CONSTITUTION:The sectional shape of the junction between a source region 11 and a drain region 13 is formed, for example, in trapezoidal shape, and the internal injection is projected in gate direction longer than the injection of the surface. The junction of this shape is formed by injection impurity ions obliquely from above of the window 17 of a wafer 16. The distance L2 between the gate and the drain and the distance L3 between the gate and the source can be formed larger than the height H2 of the channel. In this manner, the electric field concentration in the vicinity of the surface between the source region 11 and the drain region 13 can be prevented, thereby improving the withstand voltage.

Abstract: PURPOSE:To automatize a device and to take a safety measure by separating and isolating a carrying chamber from an organic solvent tank chamber by means of an isolation plate and filling the carrying chamber with nitrogen gas so that it may be in an oxygenless state. CONSTITUTION:In this developing device, the carrying chamber 15 is isolated from the organic solvent tank chamber 24 with the isolation plate 1 as a boundary and the nitrogen gas is allowed to circulate in the chamber 15 to eliminate air, that is, oxygen, so that an equipment of which electric parts are mounted is applied only in the chamber 15 without caring about the spark of the electric parts and the explosion by the spark. By accurately controlling the immersing time of a dry plate 14 for developing of following wind in solvent and a pulling-up speed from the solvent, the problem of liquid dripping pattern and stripe pattern generated at the time of developing is solved. The splashing of the developer is prevented because the specific gravity of the evaporated gas of the developer is heavier than that of the nitrogen gas and because of a fence 25, and the evaporated gas of the developer is made to pass through a filter and exhausted to the outside by a 2nd exhaust pipe 12. Thus, the developing device is automatized and the safety measure is taken.
