Title: Clean room
Inventor: SAWADA TASUKE
IPC: B01D53/22
Filed: 1992-07-08
Abstract: PURPOSE:To reject fine particle and virus other than gas and to adjust the oxygen concentration in a clean room in clean rooms using non-porous gas separation membranes. CONSTITUTION:When pressurized air is fed to a gas separation membrane 1 consisting of a non-porous membrane by using a pressurized air feed means 3, only gas in the air is dissolved in the non-porous membrane to diffuse in the membrane and permeates the membrane, not causing fine particles and viruses to permeate the membrane. And for the air that permeated the gas separation membrane excelling in oxygen selectivity, oxygen is concentrated and on the other hand, for the air that did not permeate the membrane, since oxygen is given priority in permeating the gas separation membrane, nitrogen is concentrated. The flow rate on the non-permeated side is adjusted by a flow adjusting means 5, causing the oxygen concentration in the air that permeated the gas separation membrane 1 to be adjusted. This air is fed into a room 4, permitting the room to be turned into a clean room where oxygen concentration is adjusted.

Title: Semiconductor device and its manufacture
Inventor: HORIUCHI TADAHIKO
IPC: H01L21/768
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To reduce the capacities of the lower and upper wiring layers of a semiconductor device without deteriorating the heat radiating characteristics of the wiring layers by constituting interlayer insulating films between the lower wiring layers and upper wiring layers of second insulating films having high coefficients of thermal conductivity and high dielectric constants. SOLUTION: Silicon oxide films 3A-3C having thicknesses of 1 μm are respectively formed as second insulating films between a silicon substrate 1 and a first Al wiring layer 7, between the wiring layer 6 and a second Al wiring layer 7, between the wiring layer 7 and a third Al wiring layer 8. On the other hand, the spaces between the wires of the first wiring layer 6, between the wires of the second wiring layer 7, and between the wires of the third wiring layer 8 are filled up with polyimide films 5. This structure can reduce the wiring capacity of a semiconductor device to 70% of that of the conventional structure.  In addition, since the polyimide films 5 having low coefficients of thermal conductivity are only formed between the wires of the wiring layers 6, 7, and 8, the coefficients of thermal conductivity of interlayer insulating films do not rise as a whole as compared with the case where only oxide films are used. In other words, the heat radiating property of a whole chip is not affected even when the polyimide films 5 do not contribute to thermal conductivity, because the Al wiring layers having high coefficients of thermal conductivity occupy 20-50% of the whole area of the semiconductor device.

Title: Dust core and manufacture thereof
Inventor: YAGISAWA TAKESHI
IPC: H01F41/02
Filed: 1992-07-09
Abstract: PURPOSE:To eliminate strains to a satisfactory extent by raising heat treatment temperature and provide dust cores excellent in magnetic properties. CONSTITUTION:Since dust cores are formed by compression-molding magnetic powder together with resin mainly composed of borosiloxane resin, high temperature heat treatment is available. Furthermore, there is no strain produced by differential thermal expansion during cooling time, which makes it possible to eliminate residual stress to a satis factory extent so that the plastic deformation of the magnetic powder may be allowable. It is, therefore, possible to mold with a large compression force, thereby enhancing the space factor and hence attain enhanced magnetic properties in addition to stress removal effect.

Filed: 1981-11-12
Abstract: PURPOSE:To prevent the dropping of accumulated layers of metallic vapor flow and to form vapor deposited films stably at a uniform thickness in the stage of continuous vacuum plating by providing a cover of metallic meshes on the evaporating material side of an ancillary installation disposed between the evaporating material and a material to be plated. CONSTITUTION:In continuous vacuum plating of a steel strip or the like, an ancillary installation 3 which protects a material 2 to be plated against the heat of an evaporating material 5b is provided between the material 5b and the material 2. A cover 6 made of metallic meshes is provided on the material 5b side of such installation 3. The vapor deposited layers accumulated on the surfaces of the cover 6 adhere tightly to the cover 6 at the boundary with the surface of said cover and do not drop onto the evaporating surface 5a of a crucible 5. The cover 6 receives large thermal load by radiation of heat from the surface 5a and the scattering of metallic vapor flow, but since the cover 6 is made of the meshes, the cover disperses and absorbs the same. Thus the long-term vacuum plating operation is accomplished stably.

Title: Video signal processing circuit
Inventor: SHIOMI MAKOTO
IPC: H04N9/84
Filed: 1986-08-05
Abstract: PURPOSE:To improve the band of a reproduced chrominance signal and group delay frequency characteristics and to improve the picture quality by generating a signal which is obtained by delaying a low-Pass conversion carrier chrominance signal by 1H period and removing an unnecessary side band wave with the aid of a phase shift method in a frequency conversion circuit. CONSTITUTION:The output signal of a preamplifier is inputted in a terminal 50 and a low-pass conversion carrier chrominance signal CL is extracted in an LPF 3. A 1h delay circuit 51, frequency conversion circuits 54 and 55, an adder 56 and an LPF 57 constitute one block which removes unnecessary side band waves. The phase relation (A1...An is counterclockwise) of the reproduced signal output of a main track is different from the phase relation (clockwise) of the crosstalk of the adjacent track. Therefore the phase relation of a carrier signal fC inputted in the terminals 52 and 53 is decided in order to remove the upper side-band waves of the main signal components, so the crosstalk components work to remove the lower side-band components. The design conditions of the LPF 57 can be liberally set, so that the band of the reproduced chrominance signal and group delay characteristics can be improved.
