Abstract: PURPOSE:To enable the visual sensation of degraded deodorization power from the discoloration of a pH indicator by passing a gas to be deodorized successively through an aq. complex alkali metal salt soln. separated by semipermeable membranes and pH indicator soln. having a prescribed discoloration range. CONSTITUTION:The aq. complex alkali metal salt soln. 1 and the pH indicator 2 are sealed to the parts above and below the semipermeable membrane which separates both by the semipermeable membranes 4, 5 which allow the permeation of gas such as air and malodorous materials and prohibit the permeation of these solns. The gas to be deodorized is blasted from the aq. complex alkali metal salt soln. 1 side by a blowing device 6 by which the gas is deodorized. The pH of the pH indicator soln. is decreased as well by the malodorous materials which are not absorbed and deodorized by the aq. complex alkali metal salt soln. 1 when the deodorization is successively executed and the deodorization power degrades. The pH indicator is discolored at the point of the time when the pH decreases to 7-8. The degraded deodorization power of the aq. complex alkali metal salt soln. 1 is thus visibly sensed.

Abstract: PURPOSE:To obtain an economical air conditioning system of high heat efficiency by a method wherein a heat pump is installed in at least one of a plurality of air- handling units and the heat pump is used only when an air conditioning need different from a main operation is made. CONSTITUTION:When a main operation is cooling, at first a heat source device 1 is driven to produce cold water of about 4 to 15 deg.C for cooling and make it flow through a go-passage 4 of a flowing pipe for a heat source water. In the case that cooling is needed in a division of respective air-handling units 2, 2' and 2'', a valve is opened to permit the cold water which is sent to flow through a pipe 6 into an air heat exchanger 10, and a fan 8 is driven to cool air from an air intake port 9 and blow off the cooled air for cooling the division. The cold water heated by the heat exchange reaches the heat source device 1 from a pipe 7 through a return-passage 5 for being cooled again, taking up a circulation cycle. Further, in the case that the division in the air-handling units is turned over to a heating need, cold water supply to the air heat exchanger 10 is stopped and a heat pump is driven. In the heat pump, the cold water in the return-passage is introduced into a water heat exchanger 14 (vaporizer) through a pipe 16. The cold water in the return-passage is cooled and then returned to the go-passage through a pipe 17.

Title: Waveform processing circuit for pulse generator
Inventor: MURAKAMI ATSUSHI
IPC: G01B21/00
Filed: 1989-08-24
Abstract: PURPOSE:To set the output period of a movement quantity signal to longer than a specific time by generating a phase difference which is larger than specified one when an inverted signal is inputted and when a pulse signal is inputted. CONSTITUTION:The waveform processing circuit 1 of a pulse generator outputs a movement quantity signal -int whose pulse width is larger than specific width with which a motor control circuit recognizes a signal irrelevantly to the timing between an A-phase pulse signal E1 and the inverted signal VACK.
