Title: Dual-balance type light receiving apparatus
Inventor: HAYASHI TAKESHI
IPC: G01J1/02
Filed: 1990-06-13
Abstract: PURPOSE:To cut off leakage between the mesas of two photodetectors completely and to avoid deterioration in sensitivity and detrioration in S/N ratio by completely separating two photodetectors physically. CONSTITUTION:Position aligning markers 18 are patterned on a chip carrier substrate 24 and on photodetector substrates 1-1 and 2-1. The positions of both substrates are aligned with a position-aligning bonding device having, e.g. an infrared-ray transmitting device 20 in a micron order. Thereafter, photodetectors 1 and 2 are die-bonded to the chip carrier substrate 24 by using a bonding agent 19. Thus, the photodetectors 1 and 2 are arranged highly accurately in the neighboring positions spaced by several hundreds of microns. The photodetectors wherein two light receiving parts are integrated in a monolithic pattern are separated by the means such as creeping and dicing and used at, e.g. positions indicated by broken lines. Thus, the characteristics of the photodetectors can be made equal.

Title: Power accumulator
Inventor: OOHARA SEIJI
IPC: F01K1/04
Filed: 1979-11-26
Abstract: PURPOSE: To modify thermal stress of a body of a power accumulator by forming a steam chamber between an inner container and the body of the power accumulator.  
     CONSTITUTION: An inner container 9 is provided concentrically in a body 1 of a power accumulator to form a steam chamber 8. The steam chamber 8 is made a steam heat insulating layer by a connecting hole 12. Saturated water in a container 2 is heated by a blow-off pipe 5 of a steam conducting pipe 4 for heating. When a steam valve 7 is quickly opened to feed steam to outside, pressure in the container rapidly goes down, but the temperature in the steam chamber 8 does not go down so quickly as the heat conductivity of steam is small and no steam flows. By such constitution, the temperatue of the body 1 is gradually decreased, and thermal stress can be modified. The power accumulator can be thus high-temperatured and high-pressurized and its capacity can be enlarged.
