Title: Sink-and-float type belt-shaped bag body
Inventor: KUMAGAI YUJI
IPC: E02B15/06
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a sink-and-float type belt-shaped bag body in which damage by contact with a base rock can be prevented, and in which replacement or repairing is easy. SOLUTION: As air is discharged from a float body 12, a sink-andfloat type belt-shaped bag body 10 is sunk to the seabottom 18 in the condition where upper and lower surfaces of it are covered with protective films 22. The sink- and-float type belt-shaped bag body 10 is not damaged because it is prevented from directly getting in contact with a base rock or the like even when it is oscillated by tidal currents or the like. As air is supplied to the float body 12, the sink-and-float type belt-shaped bag body 10 floats to the sea surface 20 to part a specified water zone to prevent diffusion of dirty matter such as oil or silt. Even when the protective film 22 is damaged, the protective film 22 can be partly replaced by removing bolts 24 and nuts 26, thereby cost and manhours can be reduced.

Abstract: PURPOSE:To provide a sliding contact point material which has an increased softening temp. and improved resistance to cohesion by adding a specific amt. of Al, Ga, Mn, Ni, etc. without changing the compsn. ratio thereof to an alloy material having a specific compsn. consisting of Pd and Ag. CONSTITUTION:A sliding contact point material is formed by adding 1-10% at least one kind among Al, Ga, Mn and Ni without changing the compsn. ratio thereof to an alloy material consisting of 30-70wt% Pd and 30-70% Ag.

Abstract: PURPOSE:To stabilize an X-ray device by actuating within an active area swtiching transistors, which work as high-frequency choppers when racings develop in the voltage of an X-ray tube, by providing a feed-back controlling circuit so as to prevent any oscillation. CONSTITUTION:Electric power sent from an alternating power source 1, after being rectified with a rectifier 4, is given to an inverter constituted by NPN transistors 8-11 connected in a bridge form. Then, X-ray exposure is carried out by rectifying the secondary output of a transformer 12, and giving thus rectified output to an X-ray tube 14. In addition, voltage dividing resistances (R1) and (R2) are connected to the anode of the X-ray tube 14 so as to make racings such as oscillations of the X-ray tube voltage to be detected and to make the detected result to be used as the input to a feed-back control circuit (A). Thus, transistors 10 and 11 working as high-frequency choppers are controlled to be actuated within the active area. Consequently, since damping effect can be produced, a stable operation of an X-ray device can be carried out by preventing any oscillation.

Title: Turbine type flowmeter
Inventor: KATO TAKU
IPC: G01F1/10
Filed: 1989-05-19
Abstract: PURPOSE:To detect that an impeller rotates by the inertia force when the flow rate of a fluid flowing in a passage is zero by producing a pressure difference between a first and a second pressure leading chambers by the pressure change within said passage subsequent to the completion of the use of a gas. CONSTITUTION:When a gas is used at the downstream side, the pressure in a flow passage 2a is lowered from P1 to P2. At this time, the pressure in a first pressure leading chamber 13b to which is directly supplied the pressure in the flow passage 2a through a pressure leading hole 14 and a pressure leading pipe 15a is also lowered from P1 to P2. However, the pressure in a second pressure leading chamber 13c is not immediately lowered since a throttle 16 is provided in a pressure leading pipe 15b, but gradually lowered from P1 to P2 with a time delay t1. As a result of this, when the gas is being used, the pressure in the pressure leading chamber 13b of a differential pressure gauge 13 is lowered faster than in the pressure leading chamber 13c, resulting in the pressure difference between the chambers 13b and 13c. Accordingly, a diaphragm 13d and a detecting piece 13e are shifted in a direction of an arrow X. Thus, it can be detected when the flow rate of the gas in the flow passage 2a is zero that an impeller 11 rotates by the inertia force.

Filed: 1989-05-19
Abstract: PURPOSE:To simplify measurement by a method wherein the light absorbency and specific gravity of adsorbent are measured to eliminate the influence of light absorben cy due to salt based on the measured values. CONSTITUTION:The specific gravity D of adsorbent is measured and salt concentration Xs is calculated from this specific gravity D. The salt concentration is calculated from a relational expression between the pre-calculated specific gravity and salt concen tration. Light absorbency As when the adsorbent singly comprises salt is calculated from the specific gravity D. The light absorbency of single salt solution is calculated from a relational expression between the pre-calculated specific gravity and the absorb ency. Then light absorbency Ao of the adsorbent is measured from which absorbency A of single catalyst solution is calculated. The light absorbency A of the single catalyst solution is calculated by subtracting the absorbency As when the adsorbent singly comprises salt from the absorbency Ao of the adsorbent. From this absorbency A of the single catalyst solution, catalyst concentration X in the adsorbent is calculated. The catalyst concentration is calculated from a relational expression between the pre-calculated absorbency of the single catalyst solution and the catalyst concentration.
