Title: Heat exchanger for refrigerant
Inventor: TAKEUCHI MASAYUKI
IPC: F28D7/02
Filed: 1986-06-17
Abstract: PURPOSE:To provide a heat exchanger, compact in whole size and high in heat exchanging capacity, by a method wherein, a plurality of fine fluid pipes, which are arrange in a refrigerant chamber, are wound spirally in parallel while the winding direction thereof is reversed in U-shape on the half way of the winding. CONSTITUTION:A heat exchanger, made by sealed structure, consists of a refrigerant vessel 4, provided with a refrigerant chamber 3 with the openings of an inlet port 1 and an outlet port 2, and a plurality of fine fluid pipes 5, arranged in the refrigerant vessel 4. The fine fluid pipes 5, wound spirally, are arranged in the refrigerant chamber 3 while the upper and lower ends of the fine fluid pipes 5 penetrate through a bulkhead 8 and are connected to upper and lower fluid reservoirs 9, 10 air-tightly. The fine fluid pipes 5 are wound spirally so that the upper half and the lower half thereof are wound reversely in their winding direction at the middle positions thereof while the lower half thereof are wound clockwise and the upper half thereof are wound counterclockwise when they are seen from the upper side thereof. The fine pipes 5 are U-turned at the middle position thereof. Fluid, which flows through a narrow gap in the outside of the fine fluid pipes with a high speed, flows into the wide space of the part of U-turn and the flow direction as well as the flow speed thereof are changed suddenly whereby the fluid is mixed well, unevenness in the temperature thereof may be uniformized and the heat exchanging capacity of the title heat exchanger may be improved.

Title: Wheel lock preventing device
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/62
Filed: 1982-08-17
Abstract: PURPOSE:To reduce possible occurrence of a wheel lock and eliminate reaction force of a pedal by closing a cutoff valve correspondingly to reduction of a wheel speed and opening a discharge valve when the wheel speed is further reduced. CONSTITUTION:Pressurized liquid from a master cylinder 2 is introduced to a brake 7 through a cutoff valve 9, while a reservoir 26 and a pressure recovery pump 21 are connected through a discharge valve 15 to a main flow passage 8 leading to the brake 7. By closing the cutoff valve 9 at the time of reduction of a wheel speed, elevation in pressure of braking liquid is stopped to reduce possible occurrence of the wheel lock. When the wheel speed is further reduced, since reduction/increase of the braking pressure can be performed through opening the discharge valve, the wheel lock is averted and the reaction force of the pedal is not generated due to closure of the cutoff valve at this time.

Title: Electric field measuring instrument
Inventor: TAKAHASHI HIRONORI
IPC: G01R1/06
Filed: 1993-06-14
Abstract: PURPOSE:To instrument having a simple mechanism by providing a guiding mechanism which supports an electrooptic member containing an electrooptic material in a state where the member can be freely moved forward and backward against an object to be measured. CONSTITUTION:An optical probe head 140 is provided with a bottomed pipe section 140b integrally formed with the front end section of a supporting body 14Gc and cylindrical electrooptic conversion member 140a which is slidably put in the section 140b. A small projection integrally formed with the bottom end section of the member 140a is slidably put in a small through hole 140d formed through the central part of the bottom of the section 140b. The positional relation between the member 140a and an objective lens 130 is accurately controlled by moving the head 140 in the vertical direction by driving an actuator 270 for probe so that the intensity of receiving light of a photodetecting section 160 can become the maximum. Since the member 140a moves upward when the small projection of the member 140a touches an object to be measured 260 at the time of lowering the head 140, the driving force of the member 140a does not act directly on the object 260. Therefore, damage to the object 260 can be prevented.

IPC: F01K9/00
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To improve power generating efficiency of a power plant, and maintainability by forming a pumping means for pumping low-temperature sea water in using low- temperature deep sea water as cooling water for either of thermal power generation or nuclear power generation, and specifying the position of a talking-out opening for low-temperature sea water in the pumping means. SOLUTION: A pumping pipe 1 for pumping low-temperature deep sea water is laid toward a sea floor, and a taking-out opening 2 at the front end of the pumping pipe 1 is disposed at a deeper position than water depth of 80 m (for example, 200 m) and at 20 m or more higher than the sea floor (for example, 25 m). The low- temperature sea water pumped from the pumping pipe 1 is delivered to a tank-shaped water reservoir 3 installed on a coast through an opening and closing valve 4. A water delivery opening 5 of the pipe 1 to the water reservoir 3 is installed in the sea water of the water reservoir 3 whose water level is maintained lower than sea water level.  As a result, low-temperature sea water is flowed into the water reservoir 3 automatically by a pressure difference from a difference H of elevation, and low- temperature sea water in the water reservoir 3 is pumped by a pump 10, supplied to a condenser 12 in a power plant by pumping it by a pump 10, and returned to the sea.

Title: Oil mist separating recovering device
Inventor: SERIZAWA MINORU
IPC: F01M13/04
Filed: 1994-05-31
Abstract: PURPOSE:To efficiently remove minute oil mist by accelerating flow velocity after decelerating it through a process of allowing gas containing oil mist to flow from an inflow port of an inner container to the lower part of an inner space. CONSTITUTION:In an automobile engine, when gas in which oil mist is mixed is allowed to flow into an oil mist separating recovering device through a gas inflow pipe 17, the flow velocity of gas is decreased, and oil mist is partially dropped or deposited on the inner wall of a container in a lower chamber L2 of an inner container and allowed to flow back through the gas inflow pipe 17 and recovered. When it is allowed to flow upward through a filter member 37, it is adsorbed by the filter member 37, and oil having the increased grain diameter is partially dropped on the lower chamber L2, and the rest is guided into an upper chamber L1. The velocity of flow of gas is increased by a penetrating small hole 36a1, and oil is efficiently adsorbed by collision with the lower surface of a cover body 20, and its is dropped to the lower part and recovered through an oil passing groove.

Next, when a sample introducing apparatus is turned ON to become a state (a), the mobile phase introduced into the through-hole 1a from the flow path 3 flows through the groove 1j and the through-hole 1b and further flows through the through-hole 1c, the groove 2c and the through-hole 1b to meet with a flow path 4 to be guided to the separation column. Therefore, the sample received in the sample loop 6 in the state (b) is fed to the separation column by the mobile phase while diluted therewith to be separated and analyzed.
