Title: Anticontamination device, membrane formation device and etching device
Inventor: KIN HIROITSU
IPC: C23F4/00
Filed: 1995-06-27
Abstract: PURPOSE: To prevent a membrane formation chamber from becoming internally contaminated and thereby, enhance an operating safety by capturing a reaction product from a reaction gas discharged from the chamber and at the same time, checking the backflow of the reaction product. CONSTITUTION: A reaction gas which remains chemically unreacted is allowed to flow into a reaction chamber 3 from a flow path 2 on the inlet side, than is turned to a plasmatic state by a flow path 5 formed of a pair of electrodes 4a, 4b, and is discharged to a flow path 7 on the outlet side after the completion of a chemical reaction. If the downstream pressure increases during the operation of this anticontamination device, the gas might flow back. In order to prevent the gas flowback from occurring, an operating plate for a means to check the gas flowback is disposed in the flow path 2 on the inlet side for the reaction gas. If the gas flow from a gas induction port 1 to the reaction chamber 3 is normal, the flow path 2 on the inlet side is opened, while the flow path 2 is closed, if the gas flow is reversed.  Consequently, if the gas flows back, a reaction product is prevented from flowing back to the chamber side and therefore, a membrane formation chamber is no longer contaminated.

IPC: F02B67/06
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To provide an auxiliary driving gear capable of properly and actively changing the variable speed characteristic of a passive system using a centrifugal type variable diameter pulley. SOLUTION: A variable diameter pulley B eccentrically sandwiched a power- transmitting ring 3 between pulley main bodies 1, 2 is provided on an input shaft of an auxiliary machine. An elastic member and an inertia member for energizing the ring 3 to a concentric side through pulley bodies 1, 2 are housed in the variable diameter pulley B. A motor 15 is driven to change preload of a second elastic member 9 contained in a tensioner 5, so that belt tension is changed. When the preload is small enough, the force to bias the ring 5 by tension of the tensioner 5 exceeds the force for energizing the ring 3 to the concentric side by the elastic member and the inertia member of the variable diameter pulley B. The ring 3 results in a concentric state regardless of a rotating speed, and a constant change gear ratio can be achieved.

Title: Particle board and its preparation
Inventor: MIHASHI TOMOKAZU
IPC: B32B15/10
Filed: 1986-07-11
Abstract: PURPOSE:To enhance mechanical strength, especially, bending strength without excessively increasing the density of a board, by setting the thickness of one of skin layers laminated to both surfaces of an inner layer to a predetermined value or less and holding an iron laminate between the skin layer having the predetermined thickness and the inner layer. CONSTITUTION:An iron laminate 4 is held between an inner layer 1 and one skin layer 2 among the skin layers laminated to both surfaces of the inner layer 1 and the thickness of the skin layer 2 holding said iron laminate 4 is set to 6mm or less. Since the iron laminate thus held is present at a position within 6mm from the surface of a board on the side of one skin layer 2 of the board, bending strength when the surface opposite to the skin layer 2 of the board receives stress is markedly enhanced and strength can be enhanced without increasing the wt. of the board due to the holding of the iron laminate to a large extent.

IPC: G01D21/00
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To perform highly reliable detection of a target object by using both a microwave sensor and an image sensor. SOLUTION: A received waveform analyzing part 22 performs waveform analysis of a signal received from a microwave sensor 18. Thus, an 'microwave human body value' and 'image weight' are operated. An image analyzing part 24 analyzes image information outputted from an image sensor 16. Thus, an 'image human body value' and 'microwave weight' are operated. An overall deciding part 26 performs human body decision on the basis of a value obtained by weighting the 'microwave human body value' with the 'microwave weight' and a value obtained by weighting the 'image human body value' with the 'image weight'. An erroneous information factor and an information failure can be eliminated by appropriately setting the value of each parameter.  In particular even when halation takes place, information failure can be prevented and the problem on erroneous information due to the influence of a small object such as an insect also can be coped with.
