Title: Monitor
Inventor: SASAKI TAKESHI
IPC: H04N5/58
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To keep optimum monitor luminance at all times without the need for the user to adjust the luminance of the monitor. SOLUTION: For example, a monitor luminance adjustment section 20 is installed in the vicinity of an indoor monitor master set 10a of a video intercom 10. A light receiving element 11 is used to sense the lightness of the surrounding and a luminous quantity detection section Sa is obtained from a luminous quantity detection circuit 12. A monitor luminance detection circuit 16 detects the monitor luminance of a monitor 15 and provides an output of a monitor luminance detection signal Sb. An arithmetic circuit 13 compares the signals Sa, Sb and to provide an output of a monitor luminance control signal Sc and a monitor luminance adjustment circuit 14 that receives the control signal Sc adjusts automatically the monitor luminance to be a luminance in response to the surrounding lightness. Thus, the monitor luminance of the indoor monitor master set 10a is always kept to be an optimum value.

IPC: F24H3/04
Filed: 1987-03-23
Abstract: PURPOSE:To prevent useless heating of a heat exchanger, by a method wherein a gas liquid heat exchanger and a blower are situated in a combustion gas passage, and the blower is driven according to a heat demand by a load. CONSTITUTION:A combustion gas passage 7, through which a part of combustion gas is guided, is connected to a combustion chamber 4, and a gas liquid heat exchanger 2 and a blower 8 are situated in the combustion gas passage 7. When liquid fuel, e.g., kerosene, is burnt in the combustion chamber 4 and the blower 8 is driven according to a heat demand by a load, a part of combustion gas flows in the combustion gas passage 7. If heat exchange is executed by the gas liquid heat exchanger 2 and a heating medium, heated by the heat exchanger 2, is forcibly circulated between the heat exchanger and a load 1, a heat, being necessary and sufficient to the load 1, can be supplied. Meanwhile, the heat demand by the load 1 is reduced to zero, the blower 8 is stopped, and introduction of combustion gas to the combustion gas passage 7 is shut off. Thus, heat exchange by the gas liquid heat exchanger 2 is stopped. Namely, when no heat demand is effected by the load 1, the useless increase in the temperature of the gas liquid heat exchanger 2 is prevented from occurring.

Filed: 1984-04-09
Abstract: PURPOSE:To test the nature of a paving material for a road accurately by applying a load moving only in one direction with a one-way movement mechanism. CONSTITUTION:The sample as illustrated is that a wheel 2 moves only in one direction rotating naturally with the circulation of a chain 5. In the wheel 2, a desired disc-shaped load 3 is applied to a wheel shaft 4. As a gear 6 rotates, the chain 5 circulates only in one direction and as the shaft 4 of the wheel 2 is fixed on the chain 5, the wheel 2 moves only in one direction rotating naturally with the movement of the chain 5. With one circulation of the chain 5, the wheel 2 makes one circulation in repetition. Since the load 3 is applied to the wheel 2, with the rotary movement of the wheel 2, the load of the wheel works on a sample body 1 as one-way moving load.

Abstract: PURPOSE:To shorten the time of the rise of a roll and eliminate the unevenness of the roll temperature distribution, by forming a closed magnetic path consisting of a magnetic member independently of the conductive cylindrical roll as a heating element to reduce the heat capacity of the roll part. CONSTITUTION:The alternating magnetic flux induced by the supply of an AC power to a winding 18 passes a closed magnetic path 17 consisting of an iron core 15 and a magnetic member 16. Generation of heat is caused by the current which a cylindrical roll 11 generates at this time by the induction function due to a one-turn secondary winding, and the roll 11 itself generates heat, and heat fixation is performed. The closed magnetic path 17 and the cylindrical roll 11 are formed independently of each other to reduce the heat capacity of the roll part 11, and roll side plates 12 and 13 can be formed with materials having a low heat conductivity to improve the uniformity of the temperature distribution. A winding 18 having N1S-number of turns and N1T-number of turns is provided for the purpose of shortening the time when the surface temperature of the rotating roll 11 reaches a prescribed fixable temperature. That is, AC power is supplied to the N1S side of a smaller number of turns at the power-on time and is supplied to the N1T side of a larger number of turns when the surface temperature of the roll 11 reaches the prescribed temperature. Consequently, the time of the rise of the roller temperature is shortened considerably.
