A rotational angle detecting device includes a resistor of which one end is connected to the power source and the other end is grounded, a rotary potentiometer having two wipers which come into sliding contact with the surface of the resistor, a control unit which detects voltage applied to each of the wipers depending on the positions thereof upon the surface of the resistor, two resistors connected at one end to each of the two wipers, and switching means which switch the connection state between the other end of the two resistors and the power source under control of the control unit.

Rotational angle detecting device

A liquid condensation system heats a liquid raw material under a decompressed circumstance and evaporates a volatile component from a liquid surface to condense the liquid raw material. Therefore, the liquid condensation system includes: liquid condensers, each of which condenses the liquid raw material; a vacuum pump that is in communication with the liquid condensers; and a warm water circulation system as a heating source that heats the liquid raw material in the liquid condensers. The volatile component evaporated in the liquid condensers is led to the outside of the liquid condensers through vapor lines. The condensed liquid that is not evaporated in the liquid condensers is led to the outside of the liquid condensers through condensed-liquid lines. Condensed-liquid-line adjusting valves are interposed on the condensed-liquid lines, and heaters are attached to the condensed-liquid lines. A control unit controls the heaters and the condensed-liquid-line adjusting valves.

Liquid condensation system

A dent is formed on a side surface of a first substrate. A second substrate faces to the side surface of the first substrate. A third substrate is arranged so that the first and second substrates contact each other closely. A micro flow path and a micro chamber are formed between the first and second substrates. The micro flow path and the micro chamber communicate with each other and including an inlet and outlet respectively. A fifth substrate contains the first, second and third substrates. A fourth substrate fits in the fifth substrate. The first and second substrates are pressed against each other by thread fastening (pressing means) for the fourth and fifth substrates.

Micro fluidic device

A joint to be attached to a port of a micro fluidic element, has an outer peripheral surface of truncated subulate shape at a front end portion of the joint to form a front surface as a top of the truncated subulate shape, and a cuneiform space in an inside of the joint at the front end portion of the joint, the joint is made of an elastomer, and the cuneiform space includes a front end overlapping the front surface as seen in a direction along which a tube is guided by the cuneiform space when the tube is inserted into the joint so that the tube is enabled to penetrate the front surface through the front end.

Micro fluidic device and joint therefor

The invention relates to a micro fluid chip that leads liquids supplied from a plurality of liquid supply ports, respectively, to a minute flow passage, performs mixing and reaction (chemical reaction) of the liquids in the minute flow passage, and obtains a liquid having been processed from a liquid discharge port. A micro fluid chip that leads liquids supplied from a plurality of liquid supply ports, respectively, to a minute flow passage, performs mixing/reaction of the liquids in the minute flow passage, and obtains a liquid having been processed from a liquid discharge port, the micro fluid chip comprising liquid supplies that supply a plurality of flows, which are formed by division of two kinds of liquids, respectively, in an alternate arrangement, and a flow flattening portion provided downstream of the liquid supplies to be configured in flow passage such that liquids alternately arranged are decreased in dimension as they go downstream and increased in dimension in a direction, which intersects the direction of arrangement and a direction of flow, as they go downstream, to be made substantially the same or slightly large in cross sectional area in the direction of flow. According to the invention, liquids of large flow rates can be processed at high speed and an apparatus is not made large in size.
