Title: Heat exchanger
Inventor: HIRANO AKIHIKO
IPC: F28F19/06
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To extend lifetime of a product of a heat exchanger by substantially enhancing corrosion resistance of a heat exchanging pipe to be dipped in alkaline drain hot water. SOLUTION: Alkaline drain hot water from a dish washer is stored in a hot water drain recovery tank 30. A pipe-like evaporator 27 of a component of a heat pump is contained in the tank. The evaporator 27 has a structure that an outer surface of a copper tube 62 is tin-plated 63. A normally open drain valve 40 is provided at a bottom of the tank 30. In the case of heat exchanging, while the evaporator 27 is dipped in the drain, the tin functions as a sacrificial anode to the copper to be preferentially dissolved in the drain to prevent corrosion of the tube 62 as long as the plating 63 is retained. Each time the heat exchanging is finished, the valve 40 is opened, the drain is immediately discharged, corrosion reaction time is largely shortened to suppress corrosion of the plating 63 itself as well.

Patent JP-H0688667-A (JP)
Title: Refrigerator
Inventor: HARA YASUO
IPC: F25D17/06
Filed: 1992-09-07
Abstract: PURPOSE:To obtain a refrigerator which prevents a remarkable increase of a temperature in the refrigerator even in a state that a door is loosely closed, by providing a stopping means for stopping the operation of air circulating fans, if a temperature in the refrigerator is abnormally outside a range of a holding temperature, on the basis of a temperature in the refrigerator which is detected by a temperature detecting means. CONSTITUTION:In the case where it is assumed that a heat-insulating door of a refrigerator is not securely closed but loosely closed, a temperature T in the refrigerator is stopped at a level higher than temperature TC to be detected. During a period of this time, a CPU refers to a value of a counter for an abnormal state while instructing a cooling operation and judges whether a predetermined period of time 'ty' has elapsed. Since fans 30a, 30b in the refrigerator circulate air in the refrigerator, cooled air is leaked positively and, even in the case of a timing 'c', the temperature T in the refrigerator remains at the level of an abnormal temperature. When the value of the counter for the abnormal state exceeds the predetermined period of time 'ty' at a timing 'f', the CPU stops the operation of the fans 30a, 30b in the refrigerator. As a result, the temperature T in the refrigerator drops to enter a range of a holding temperature.

Title: Optical pickup and optical head
Inventor: KONO HARUHIKO
IPC: G11B7/135
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To allow different amount of heat to be radiated from first and second light sources so as to suppress difference in temperature between the respective light sources during operation to the minimum level, and improve the lifetime and operation stability of the light sources, by setting the size of the first light source to be different from the size of the second light source. SOLUTION: Light sources 2 and 9 respectively perform recording or reproducing operation for recording mediums different from each other. Since a different amount of light is required, optical outputs as well as temperatures during the operation are different from each other. The size of the light source 2, more specifically, the area, in which the light source 2 is in contact with other components, is made to be different from that of the light source 9. For example, in the case where an output of the light source 2 is larger than that of the light source 9, the contact area of the light source 2 is designed to be larger, thereby allowing a lager amount of heat to be released per unit time by heat conduction, as compared to the light source 9.  Furthermore, a larger amount of heat can be radiated from the light source 2 than from the light source 9 by designing a surface area of the light source 2 to be larger than that of the light source 9.

Abstract: PROBLEM TO BE SOLVED: To satisfy the viewing angle of a still image and a viewing angle of a dynamic image with different adaptability from each other, at the same time in simultaneous recording of the still image and the dynamic image. SOLUTION: A frame memory 19 temporarily stores full pixel data obtained by a high pixel image-pickup element 4 and an FIFO image memory 15 stores a part of the full pixel data, obtained by the high pixel image pickup element 4 in a consecutive form by a prescribed time, while being segmented at a position and a size of a proper viewing angle by a dynamic image segmentation section 9. When a simultaneous recording trigger button 16 is depressed, a card recording operation section 18 records the full pixel data stored in the frame memory 19 as in image data. At the same time, a VTR section 30 reads the image data stored in the FIFO image memory 15, in response to a dynamic image recording start and end time set by a user and records them as dynamic image data.
