IPC: H01L31/052
Filed: 1991-05-31
Abstract: PURPOSE:To improve efficiency of power generation in solar power generation. CONSTITUTION:Solar light 32 is converged by a convex lens plate 12, drawn through an opening 14a of a light reflecting plate 14 and diffused and injected to a heater 20 in a heat insulating chamber 28 by a concave lens plate 16. A heater 20 is heated in the heat insulating chamber 28 by using light energy which solar light 32 has as heat energy. Reflected light which is not absorbed by the heater 20 is reflected by a light reflecting layer 14b excepting a little light escaping outside through the opening 14a and enters into heat generation function of the heater 20. Through heat generation of the heater 20, light which has spectrum distribution of a narrow wavelength region which is proper to the heat generator 20 is reflected and injected to a solar battery 30. Characteristics which have spectral sensitivity in a narrow wavelength region are adopted as the solar battery 30 and reflection light from the heater 20 is entirely made light energy which is effective for power generation, thereby improving power generation efficiency.

Title: Buffer control system
Inventor: HISADA TOSHIYA
IPC: G06F12/02
Filed: 1989-06-20
Abstract: PURPOSE:To improve speed for buffer copy processing by using a buffer attached with a processing module number field to describe the number of processing modules equipped with the ownership right of the buffer. CONSTITUTION:When plural processing modules 2 and 3 posess one buffer, the number of the processing modules is described to the processing module number field attached to the buffer. This is because the number is increased by 1 when the buffer is copied. When the buffer is released, the buffer can be released by the processing modules 2 and 3 regardless of the other module. This is because a buffer managing module 1 checks the processing module number field attached to the buffer and determines whether the buffer is added to an unused buffer group or not. Accordingly, for copying the buffer, it is not necessary to physically copy the buffer but it is enough to only simply increase the processing module number of the processing module number field by 1. Thus, the processing to copy the buffer can be executed at high speed.

Title: Roof membrane anchor structure of low-temperature tank
Inventor: SATO SHIGETO
IPC: F17C3/06
Filed: 1991-06-28
Abstract: PURPOSE:To prevent distortion of a membrane due to thermal contraction by connecting a roof and a membrane to each other by an anchor member, and connecting the anchor member to the roof by a universal joint. CONSTITUTION:A roof portion 50 is constructed so that a membrane 10 is suspended from a universal joint 12 fixed to a roof 13 so as to allow the relative movement in the surface direction of the roof 13 and the membrane 10. Accordingly, When a stored liquid is raised by sloshing due to earthquake or the like and again lowered, even if the membrane 10 is subjected to negative pressure from the stored liquid to be sucked downward, it is not separated. Further, a sleeper 22 for cutting off thermal conduction is provided on the roof 13, thermal conduction is interrupted by an anchor member 11 and a cold insulation material 25 is filled in a void portion 15 so as to accomplish heat insulation. When a lower temperature liquefied gas is put in a tank 30, though the membrane 10 directly comes into contact with the gas phase of the low temperature liquefied gas to be cooled, the roof 13 is insulated from heat by a cold insulator layer 14 not to be thermally contracted. Thus, distortion of the membrane 10 can be prevented.
