Title: Measurement system for gas concentration
Inventor: SAWADA AKIRA
IPC: G01N21/61
Filed: 1984-05-31
Abstract: PURPOSE:To perform a measurement with high sensitivity by using a laser diode as a light source and measuring two minimal points of a secondary derivative measuring method, approximating a base line by a straight line connecting the two points together and making an offset correction, and measuring the concentration of gas. CONSTITUTION:A laser light source C supplies a current which is proportional to the sum of a DC voltage from a D/A converter A and an AC voltage from an oscillator B to the laser diode D. Light emitted by the D illuminates a sample F through a lens E and is condensed on a detector I through a lens G. The output of the I is detected by a lock-in amplifier J, which is supplied with a signal of frequency twice as high as that of the output of the B as a reference signal. The output of the J is inputted to a computer L. A laser driving current (i) is set to (a) and (c) to measure minimal values (h) and (f) of the secondary derivative method. The computer L computes (g) by interpolating two points (a,b) and (c,f). Then, the current (k) is set to (b) to calculate (e), and the concentration of sample gas is measured from a value e-g. Thus, the gas concentration is measured with high sensitivity.

Title: Four-way valve
Inventor: TAKAHASHI IKUO
IPC: F16K11/074
Filed: 1991-05-17
Abstract: PURPOSE:To promote the disuse of piping as well as to seek structural simplification by installing a means, regulating each rotation of a main valve element and a support plate, in each of specified connecting and interrupting positions, in a four-way valve which has the main valve element, the support plate concentrically rotatable with this valve element and a sub valve element or the like installed in the support plate. CONSTITUTION:When a compressor is stopped and a stepping motor M is energized with current, turning effort of a permanent magnet 12 is transmitted to a pinion 11, and both main and sub bevel gears 8, 9 are rotated. At this time, since frictional force acting in space between a sub valve element 4 and a sub valve seat 2d being relatively small in an area is relatively small, only a support plate 5 of the sub valve element 4 is rotated, and this valve seat 2d is opened. When a projecting part 5a of this support plate 5 comes into contact with a projecting part 1e of a valve box 1, the main bevel gear 8 is rotated by the pinion 11. In addition, a main valve element 2 is rotated, and thereby this projecting part 2c comes into contact with the projecting part 1e of the valve box 1. In consequence, a high pressure refrigerant forms such a heating circuit as returning to a compressor from another compressor by way of both indoor and outdoor heat exchangers.
