Title: Pressure regulator
Inventor: NAKAMURA MUTSUMI
IPC: G05D16/06
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To enlarge the capacity of a pressure regulator without making a diaphragm large in size. SOLUTION: A low pressure diaphragm 103 is displaced in accordance with the pressure change of a low pressure chamber 101 and a low pressure valve 115 is opened and closed to adjust the pressure of the chamber 101 when it is a small amount of flow rate. In such a time, there is little pressure difference between the upstream and downstream of an orifice 120 and due to this, a low pressure diaphragm 133 for supply of a low pressure reducing 131 for supply is displaced to make a bypass valve 149 open.  When a gas flow rate increases and its flow speed increases, pressure loss takes place between the upstream and downstream of the orifice 120, the pressure on the downstream side falls, the diaphragm 133 is displaced by the pressure difference between this pressure drop part and a low pressure reducing chamber 137 for supply communicating with the upstream side of the orifice 120, and the valve 149 is opened. Thus, gas caused to flow into a gas entrance channel 53 passes into a gas exit channel 65 from the chamber 137 through a bypass nozzle part 147a.

Abstract: PROBLEM TO BE SOLVED: To allow heat injection molding an recycle, and to improve repulsion performance by finely dispersing diene rubber dynamic cross-linked by a resin vulcanizing agent in an ionomer to make elastic material with a specified value of bending elastic modulus. SOLUTION: For example, ethylenepropyrene diene ternary copolymer is used as diene rubber, and fine-dispersed as crosslink rubber dynamic crosslinked by a resin vulcanizing agent in ionomer. As ionomer, metal ion neutralized material of α-olefin and α,β-unsaturated carboxylic acid copolymer is used. The weight ratio of ionomer to diene rubber is 35:65-95:5. In the case of attaching much importance to reactivity, preferably butadiene rubber is used, and in the case of attaching much importance to workability, an ethylene propyrene diene ternary copolymer is preferably used. The bending elastic modulus of elastic material to be formed is 600-3000 kgf/cm<2> . Further a compatible agent may be mixed. Thus, bending elastic modulus, repulsive index, moldability and a feeling of hitting a ball can be improved.

Title: Inspection method for printed wiring board
Inventor: MOTOGAMI MITSURU
IPC: G01R27/02
Filed: 1993-11-08
Abstract: PURPOSE:To inspect the characteristic impedance easily and inexpensively by forming a conductor insulating material having known thickness into a wiring pattern and then determining the DC resistance and the width of a wiring conductor. CONSTITUTION:Assuming that the width of wiring conductor is W, the distance between probes is L, the conductivity and the thickness of the wiring conductor are delta and t, the indicated value of a potentiometer is V, and a conducting current is I, W=L(R0tdelta) is satisfied from the DC resistance of the wiring conductor R0=L/(Wtdelta)=V/I. Since the conductivity delta is known, the thickness t is controlled to be constant in the manufacturing process, and the distance L of the potentiometer 22 is also known, the width W is a function only of the resistance R0. Consequently, the characteristic impedance Z0 of wiring conductor can be represented, as a function of only the resistance R0, by Z0=G(R0)=G(V/I). The impedance Z0 can be determined according to the formula by measuring the resistance R0 while fixing the interval of probe for both a constant current source 21 and a potentiometer 22.

Abstract: PURPOSE:To easily measure the influence that various kinds of chemical materials and the materials derived from living bodies exert on cell clusters by constituting the biosensor of a detector for the epithelia cells, cell substrate membrane and the metabolite of the cells. CONSTITUTION:The epithelia cells 2 are adhered and grown on the cell substrate membrane 1 contg. collagen and having material permeability to form the cell clusters. The substrate membrane 1 is brought into contact with a test liquid 5 in a vessel 6 and a medium 4 is filled on the cell 2 side. The detector 3 is disposed in the liquid. If glucose is placed on the substrate membrane 1 side, the cells decompose the glucose and discharges lactic acid as the metabolite to the substrate membrane 1 side and ammonia to the cell 2 side. A concn. difference of the glucose and the metabolite, therefore, arises between the cell 2 side and the substrate membrane 1 side if there are no spacings between the cells A and the cells do not cause metabolism abnormality. The defect between the cells and the metabolism abnormality are detected if such concn. difference is measured. The influence of a material desired to be measured of pharmacological toxicity on the cells can be measured by acting this material on the cells having the normal metabolism function.
