Filed: 1990-11-07
Abstract: PURPOSE: To obtain a separation membrane having a high mechanical strength, oxygen permeability and selectivity by laminating a sulfonated polysulfone layer, a polysiloxane grafted layer and a silicone rubber layer on a porous polysulfone layer. CONSTITUTION: The surface of a porous polysulfone membrane is treated with a sulfonating agent to form a sulfonated polysulfone layer, and the sulfonic acid group in this sulfonated polysulfone layer is subjected to silylation with a reactive polysiloxane to form a polysiloxane grafted layer. Furthermore, this polysiloxane grafted layer is treated with a coating polysiloxane and a crosslinking agent to allow crosslinking with a coating to form a silicone rubber layer. A multilayered composite membrane for oxygen enrichment obtained through such process has a high mechanical strength and exerts a good permeability and selectivity of oxygen against nitrogen.

IPC: G02B6/28
Filed: 1987-11-27
Abstract: PURPOSE:To constitute the title tuner of optical members having a simple shape by selecting the electric signals converted by plural photodetecting elements by a switch. CONSTITUTION:Five different rays from an input optical fiber 3 are entrained in the rays of light consisting of five different wavelengths and these rays of the light are projected diagonally on a plane linear diffraction grating 1. The rays of the light consisting of the five different wavelengths are reflected at the angle varying with each wavelength by receiving wavelength dispersion and are condensed by a lens 2 so that the rays of the light respectively having the different wavelengths are focused on the respective photodetecting surfaces of the photodetecting elements 4-8. The electric signals converted by the plural photodetecting elements 4-8 are selected by the switch 9 to select the signal of the required wavelength from the plural wavelengths. The optical tuner is thereby formed with the simple structure.

Title: Gas shut-off device
Inventor: SAKATA MASAAKI
IPC: F24C3/06
Filed: 1986-12-17
Abstract: PURPOSE:To improve the safety by changing determining conditions to conform to the real seasonal situation by observing actual gas consumption patterns for a certain period for each season. CONSTITUTION:When a start signal applying means 12 is activated by an external setting unit 6 through an external signal control section 15, a start signal is sent to a timer 11 to start the counting of predetermined period. At the same time, data is updated in a seasonal consumption conditions memory section 13 selected by the external setting unit 6 in order to memorize the maximum value of the gas consumption pattern. When the counting is completed, the latest data are sent from the seasonal consumption conditions memory section 13 to a suitable consumption conditions changing section 14, where the initial data and latest data are compared, and new conditions are reset to the safe side. Meanwhile, where there are variations of gas appliances and their usage time according to the seasons, consumption patterns for each season are similarly memorized in a seasonal comsumption conditions memory section 13. Since the seasonal consumption conditions memory section 13 memorizes two consumption patterns, the switching to suitable conditions can be done by the external setting unit 6 when the season changes from the following year.

CONSTITUTION:The surface of a p<-> semiconductor substrate 11 is formed to be high in a memory cell region and to be low in a peripheral circuit region. An n<+> type buried semiconductor layer 12 whose thickness is substantially uniform and whose impurity concentration is high is formed on the surface of the p<-> semiconductor substrate 11. Consequently, also the surface of the buried semiconductor layer 12 has a difference in level between the memory cell region and the peripheral circuit region. An n<-> type epitaxial layer 13 whose impurity concentration is low is formed on the surface of the n<+> type buried semiconductor layer 12. Since the surface of the epitaxial layer 13 is formed to be of the same height at the memory region and the peripheral circuit region, the film thickness E1 of the epitaxial layer 13 is thin in the memory cell region and the peripheral circuit region id thick at E2. A U-shaped stepped part 16 is formed in the boundary part between the memory cell region and the peripheral circuit region on the surface of the epitaxial layer 13.
