Abstract: PROBLEM TO BE SOLVED: To realize a heat sink that is capable of absorbing vibrations keeping high in heat dissipating effect by a method wherein a heat transfer sheet is interposed between a heat releasing body and a heat sink, they are bound together with a binding means, and the heat transfer sheet is made to have a vibration absorbing function. SOLUTION: A heat transfer sheet 20 is composed of two parts that are corresponding to a temperature distribution on the heat releasing surface 31a of a hard disk drive device, where the two parts are composed of a part that comes into contact with the comparative low-temperature part of the heat dissipating surface 31a and is provided with a large number of through-holes 20a and a part that comes into contact with the high-temperature part of the releasing surface 31a and its vicinity and is provided with through-holes 20a which are gradually lessened in number and area as they approach the high-temperature part. A heat sink, the heat transfer sheet 20, and a hard disk drive device are firmly bound together with a pressing plate 40 and screws 42.  The high temperature part of the heat releasing surface 31a gets wider in contact area than the low-temperature part, so that the high- temperature part is capable of transferring more heat to the heat sink than the low- temperature part. Air present in through-holes provided to the heat transfer sheet 20 serves to absorb the vibration energy of the hard disk drive mechanism, so that the heat sink is capable of absorbing vibrations keeping its heat dissipating properties high.

Title: Buffer-type gas circuit breaker
Inventor: UEMATSU HIROBUMI
IPC: H01H33/91
Filed: 1988-10-06
Abstract: PURPOSE:To improve arc-extinguishing performance by a method wherein a heat gas chamber is formed between a driving rod and a buffer chamber and the hot gas chamber is opened close to the tip of a movable arcing contact. CONSTITUTION:A heat gas chamber 21 is provided between a buffer chamber 9 and a movable arcing contact 7. When a gas circuit is to be cut, by separating the movable arcing contact from a fixed arcing contact 3, pressure of insulation gas rapidly rises due to arc heat generated between poles to permit gas to gather in the heat gas chamber 21, and arc is extinguished with the insulation gas blown against the arc from an opening 23. Then, insulation gas in the buffer chamber 9 pushed out by a piston 17 rapidly raises insulation recovery characteristics between the poles to complete cutting the gas circuit. The larger the cutoff current, the larger the arc energy, to increase pressure of the insulation gas in the heat gas chamber to have arc-extinguishing performance improved.

Title: Cooker
Inventor: KONNO SETSUZOU
IPC: A47J27/00
Filed: 1989-09-27
Abstract: PURPOSE:To prevent the taste and form of a cooked material from being deteriorated due to drop of dew inside a lid during warming by applying an electric current to a Iid heating portion at full power when the temperature of the lid is less than a designated temperature and reducing the electricity application rate to the lid heating portion when it is above a designated temperature so as to control the temperature of the lid to a fixed level. CONSTITUTION:Signals of a lid temperature detecting means 10 and a pot temperature detecting means 9 are input to a control means 11, and the control means 11 controls a bottom heater driving means 6 and a drum heater driving means 7 so that the temperature of the pan 1 is a certain temperature theta1 in a warming process, controls the lid heater driving means 8 to apply an electric current to a lid heater at full power when the temperature of a lid 4 is below a certain temperature phi1, and controls the lid heater driving means 8 to reduce the electricity application rate to the lid heater 5 when the temperature of the lid 4 is above a certain temperature phi1, so that the temperature of the lid 4 is controlled to be at a fixed temperature phi2. Thus, dew is difficult to adhere to the inside of the lid so that the taste and form of a cooked material in the pan can be prevented from being deteriorated due to drop of dew in the pan.

Abstract: PURPOSE:To eliminate the need for adequacy check of a line pen designation address by applying interruption to a computer main body only with correct light pen input and transmitting a data representing an area corresponding to light pen designation address to the computer main body. CONSTITUTION:In touching a light pen 13 to a desired position on a display plane of a display monitor 11, a switch of the pne 13 is turned on. A display control section 12 detects the pattern address of the position and gives it to a protect/unprotect discriminating section 15. The discriminating section 15 references the memory 14 to extract a protect/unprotect setting data A set in an area designated by the said address thereby discriminating at which area the corresponding address is included. If the address is included in the protect area, the pen input is neglected and no interruption is generated.When the address is included in the unprotect area, interruption is applied to the computer main body 20 and a corresponding area identifier is transmitted to the computer main body 20 as the interruption data.
