Title: Radio paging receiver
Inventor: ISHII DAISUKE
IPC: H04Q7/00
Filed: 1981-07-21
Abstract: PURPOSE:To smoothly communicate a caller with the carrier of a receiver, by informing the state of impossible reception to the carrier, if the receiver can not receive a reception signal for a prescribed time or over. CONSTITUTION:Electromagnetic waves received in an antenna 1 are demodulated at a reception 2, transmitted to a collation section 4, compared with the storage of an ROM3, transmitted to a driving section when coincident, and drive a speaker 6 and a display section 7. On the other hand, an output of the section 2 is transmitted to a signal detection section 8 and a detection signal is outputted when a specific signal is hardly recognized in the degree of reception of a signal from a transmitter. The ouput signal is transmitted to an integration section 9 and the integrating time is calculated. In this case, when the integrating time is elapsed for a prescribed time, an outout signal of the section 9 is displayed on a display section 7. The receiver in the impossible reception state is informed to a carrier of the receiver.

Title: Production of chlorine dioxide
Inventor: TAKU KAZUO
IPC: C25B1/26
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To produce chlorine dioxide to be used as a disinfectant for water in a form of a chlorine dioxide soln. by producing chlorine dioxide by electrolysis of a sodium hypochlorite soln. and separating chlorine dioxide in the electrolytic liquid by using a heating vacuum deaeration column. SOLUTION: A circulation tank 20 for an electrolytic soln. consists of an upper vapor deaeration column 23 equipped with a contact packing material 25 and a lower liquid reservoir 21. The deaeration column 23 is connected to a vacuum generator 50 to render the inside of the circulation tank 20 in a reduced pressure state. Sodium chlorite (NaClO3 ) in a sodium chlorite soln. (electrolyte liquid) is partly electrolyzed to produce chlorine dioxide in an anode chamber 14 of a cation exchange membrane type electrolytic cell 10. The produced chlorine dioxide is present in the liquid phase of the electrolytic soln. Then the electrolytic soln. is sprayed in the deaeration column 23 to vaporize the water content in the electrolytic soln. The produced chlorine dioxide is vaporized from the liquid.  The electrolytic soln. is brought into contact with water vapor vaporized from the surface of the packing material 25 in the deaeration column 23 to absorb the chlorine dioxide in the electrolytic soln. to the water vapor. Thus, the vapor is continuously collected to the outside of the deaeration column 23 by a vacuum generator 50.

Title: Exposure controller
Inventor: SHIMIZU TAKUMI
IPC: G03G15/01
Filed: 1994-05-26
Abstract: PURPOSE:To appropriately adjust exposure quantity of a second and succeeding colors without using a large scaled memory by using picture data for plural colors which are simultaneously generated in a picture processing part. CONSTITUTION:The same picture signal is repetitively outputted from a picture input part 12 whenever the toner pictures of the respective colors are formed. A chrominance signal conversion means 40 converts the picture signals of the plural colors, which are outputted from the picture input part 12, into the picture signals of a developing color. On the other hand, a correction data operation part 18 discriminates the developing color at that time based on the chrominance signals inputted in accordance with the forming order of the toner pictures and calculates the correction value of the exposure quantity of the developing color based on the discrimination result and the picture signals of the plural colors, which are outputted from the chrominance signal conversion means 40. Thus, picture information until a former stage, which are obtained by using the large scaled memory so far, can be obtained with simple constitution without the memory.

Filed: 1989-05-08
Abstract: PURPOSE:To eliminate unnecessary power consumption and reduce adverse affection of noise to circumferential circuits by a method wherein an input for an oscillating circuit is stopped when a no-load signal is received, in a DC-DC converter. CONSTITUTION:An input power source control circuit 6 supplies DC input to an oscillating circuit 1 by an signal from outside while the oscillating circuit outputs an AC voltage. The AC voltage is transformed by a transformer 2 and, thereafter, is converted into a DC voltage in a rectifying circuit 3 and is stabilized in a constant voltage circuit 4, then, is supplied to a load. When there is any load, a detecting signal is not outputted from a no-load detecting circuit 5 and, therefore, the input power source control circuit 6 continues to supply a DC power source voltage to the oscillating circuit 1. When the load is removed, an output current is zero and, therefore, a signal showing there is no load is outputted from the circuit 5 while the circuit 6 receives the detecting signal and stops the supply of the power source input to the oscillating circuit 1. Accordingly, power consumption in the oscillating circuit 1 may be eliminated upon no load.
