Filed: 1987-07-13
Abstract: PURPOSE: To improve rising of cooling operation by controlling the driving of a fan for cooling a compressor such that driving of the compressor is delayed thereby circulating refrigerant smoothly immediately after driving compressor. CONSTITUTION: When the temperature detected by an inner temperature sensor 9 exceeds a set level, a relay 8a for driving a compressor 5 is turned on to drive the compressor 5 and a refrigerator is cooled. Time is then counted by a timer 12 built in a microcomputer 10 and a preset time is elapsed, a relay 11 for driving a fan 6 is turned on to drive the fan 6 thus cooling the compressor 5.

Abstract: PROBLEM TO BE SOLVED: To utilize an object selection pointer having interaction with other items. SOLUTION: The field of an effective force acting between the display of a virtual mouse selection pointer 4 displayed on a screen and various selective items is virtually formed by the interaction secured between the pointer 4 displayed on the screen and the selective objects in regard to the effects of both mathematically obtained attractive force and repulsive force. The effective radius 2 or boundary 3 of the effective force field are calculated so as to exist between the pointer 4 having the mathematical value against the mass and the object having the mathematical value against the mass. When the pointer 4 displayed on the screen enters the inside of the boundary 3 of a certain object, an actual mouse selection pointer 5 is instantaneously attracted toward the object by the attractive force.

Title: Measuring method and device residual chlorine
Inventor: MURAYAMA TAKESHI
IPC: G01N27/416
Filed: 1980-12-12
Abstract: PURPOSE:To rapidly measure a concentration of a residual chlorine in a liquid to be measured by means of a simple work, by a method wherein the residual chlorine is replaced with I2 by the penetration if KI through a diaphragm and addition of the KI to a liquid to be measured, and a quantity of electricity is measured by electrolyzing the I2 under a constant potential. CONSTITUTION:With a piston 11 operated, a liquid 7 to be measured is sucked and induced to a diaphram tube 13, and is kept in a static condition in the diaphragm 13. Meanwhile, a crystal 31 of phthal acid calium and a crystal 32 of KI exist in an electrolytic cell 2, and thereby an electrolyte 23 is prepared into a saturated solution. Thereby, a wide difference in concentration in terms of a KI between the liquid to be measured in the diaphragm tube 13 and the electrolyte 23 in the electrolytic cell 2 is produced, a KI in the electrolyte 23 penetrates through the diaphragm and moves to the liquid to be measured in the diaphram tube 23, and a residual chlorine contained in the liquid to be measured separates out I2. The I2, generated in the electrolyte 23 in the electrolytic cell 2, is reduced to I<-> through the pressure of an activated charcoal 33. By measuring the quantity of electricity required for changing the I2 into the I<->, a residual chlorine in the liquid is measured.
