Title: Ceramic board
Inventor: TAKEUCHI MASAHIKO
IPC: H05K1/11
Filed: 1988-11-15
Abstract: PURPOSE:To allow the printing condition of each through hole to be set on a constant condition regardless of the thickness of a board and make connection between surface and rear conductors perfect after stabilizing it by chamfering a single side or both sides of through hole parts, thereby providing inclined parts. CONSTITUTION:A single side tapered through hole 2 or a double side tapered through hole 3 are formed on a ceramic board according to the thickness of a board. If the thickness of ceramic board 1 is thin, it is better to have the single side tapered through hole 2 and if the thickness is thick, it is better to use the double side tapered through hole 3 and sectional parts of the inside of each through hole are made to have the same forms. Then each surface conductor 4 is printed to have a thick film on one face of the ceramic board 1. When parts where tapered parts are formed are observed in the inside of each through hole, the same surface conductors 4 are formed. Further, each rear conductor 5 is printed on the other face of the ceramic board 1 and thus surface and rear conductors 4 and 5 are connected at the insides of both through holes 2 and 3.

Title: Flow-rate measuring device
Inventor: KONO YASUSHI
IPC: G01P5/12
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a small flow-rate measuring device by which a flow rate can be detected with high accuracy irrespective of the flow direction of a fluid. SOLUTION: A heating resistor 30 is set at a reference temperature which is higher than that of an intake-temperature detecting body 20 by a fixed temperature. A flow- rate detecting body 21 is arranged and installed on the upstream side from the heating resistor 30 with respect to the forward direction of an intake flow. The heating resistor 30 is bent in a plurality of numbers of times so as to be at right angles to the direction of the intake flow, and it has a prescribed width in the direction of the intake flow. As a result, heat is hardly transmitted to the direction of the intake flow of the heating resistor 30.  When the upstream part of the intake flow of the heating resistor 30 is cooled by the intake flow and when the temperature in the upstream part of the intake flow becomes lower than the reference temperature, the temperature in the downstream part of the intake flow becomes higher than the reference temperature so that the temperature of the heating resistor 30 can be kept at the reference temperature. When the direction of the intake flow is reversed, also the temperature distribution of the heating resistor 30 is reversed. Consequently, when the temperature of the flow-rate detecting body 21 is compared with the reference temperature, the amount of the intake flow and the direction of the intake flow can be detected.

Filed: 1992-10-06
Abstract: PURPOSE: To carry out enhanced gas separation without the need for an external cooling source under optimum temperature conditions by disposing an internally generated self cooling retention means controlled to lower the average temperature of an absorption medium bed. CONSTITUTION: An absorption vessel 1 having the self-coolable PSA bed has a drying section 5 between heat regeneration zones 4 and 6. The absorption medium bed 7 exists on the drying section 5 and is constituted as a main region for selective nitrogen absorption from air. The temperature shift of the absorption medium bed 7 of a zeolite sieve existing in an equilibrium state with the air is, about -5 deg.C when the bed pressure changes from 150 kpas to 50 kpa and is about -6 deg.C in the case of the pure nitrogen and about -2 deg.C in the case of the pure oxygen. This temperature fall occurs near the supply end of the absorption bed 7 which is the nitrogen absorption zone and further, the smaller temperature fall occurs downstream of the absorption bed 7.  The internal cooling of the substantial quantity is spontaneously generated in the process of the PSA process cycle in which such pressure change occurs.
