Title: Lighting device for high-frequency heating device
Inventor: KOU SHIYAKUGEN
IPC: H05B6/80
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To increase a quantity of light applied into a heating chamber thus increasing the brightness of the heating chamber by mounting a lamp on an upper plate portion of the heating chamber. SOLUTION: To increase the brightness of a heating chamber 20 of a high-frequency heating device which can cook food using a high-frequency wave, a transmitting hole 21b is formed in an upper plate 21 of the heating chamber 20 and a lamp 41 is disposed outside of the transmitting hole 21b. A protective glass 42 which protrudes toward the heating chamber 20 is mounted in the transmitting hole 21b so as to protect the lamp 41. A reflection member is located above the lamp 41 so as to project all light radiated from the lamp 41 to the heating chamber 20. The diameter of the transmitting hole 21b is set to equal to less than 19mm, while a filament 41a of the lamp 41 is disposed 2mm above the transmitting hole 21b.  Due to such a provision, the leakage of high-frequency wave can be prevented and the rupture of the filament 41b which may be caused by the high-frequency wave can be also prevented. Furthermore, since the lamp 41 is mounted on a front portion of the upper plate 21, the permeability at the front portion of a door can be improved.

IPC: C08J11/04
Filed: 1993-02-22
Abstract: PURPOSE:To prevent a degradable polymer from mixing with a nondegradable polymer in the recovery of polymers. CONSTITUTION:A degradable polymer composition is distinguished from a nondegradable polymer composition by coloring the degradable polymer composition. Thus, the degradable polymer is colored so that it is differentiated from the nondegradable polymer in appearance. Hence, it becomes possible to fractionate the degradable polymer from the nondegradable polymer in the recovery of polymers.

Title: Combustion controller
Inventor: ICHINOSE AKIYOSHI
IPC: F23N5/24
Filed: 1979-03-19
Abstract: PURPOSE: To prevent the generation of large sound and deflagration in case of ignition by a method wherein slow ignition or soft starting is performed.  
     CONSTITUTION: When pre-purge time is completed at time T 1 , a relay X p  works and a contact XP a  is at ON, electricity is conducted to a fuel feeder 3. In this case, a contact XF a  is at OFF because flames are not detected, and a contact XIG b  is at OFF because post-ignition time is not also finished. Consequently, power is supplied through series resistance 21, 22 at that time. Thus, the suction pressure of an electromagnetic pump functioning as the fuel feeder 3 becomes lower or an angle of opening or closing of a solenoid valve becomes smaller. If flames are detected by means of a flame eye 7 at time T 2 , a flame detecting relay XF works at time T 3  later than T 2  by several seconds, and the contact XF a  is at ON. Thus, series resistance 21, 22 is short-circuited after the time T 3 , and electric energy to the fuel feeder 3 increases.

Title: Low temperature three-dimensional c4 bonding method
Inventor: TOMASU PATORITSUKU GOORU
IPC: H01L21/60
Filed: 1995-02-21
Abstract: PURPOSE: To provide a method for flip-chip bonding an integrated circuit chip to a chip carrier. CONSTITUTION: A high melting point composition, e.g. a binary alloy of Pb/Sn, is applied to a contact on a chip, for example, and a low melting point component, e.g. Bi or Sn, is applied to a contact on a chip carrier, for example. The chip and the chip carrier are then heated. Consequently, the low melting point composition, e.g. Bi or Sn, is fused to produce a low melting point alloy of Bi/Sn, for example. The low melting point alloy dissolves the high melting point composition, e.g. Pb/Sn. Consequently, a solder bond of third low melting point composition, e.g. a ternary alloy of Bi/Pb/Sn, is produced.

IPC: E21D9/087
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent interference with an entrance of a projection by providing a fixing cutting blade frontward of the projection to the outside of a shield frame. SOLUTION: A fixing cutting blade 30 is provided frontward of a projection 16 such as a simultaneous back-fill agent injector in a shield frame 10. The entrance peripheral part of the shaft earth retaining wall of a starting shaft and a reach shaft is formed by using a new material concrete wall. The cutter 11 of the edge of the shield frame 10 of a shield excavator 3 directly excavates a new raw material concrete wall, so that in the case where an entrance is formed, a fixing cutting blade 30 attached to the shield frame simultaneously excavates at a position corresponding to the projection 16 such as a simultaneous back-fill agent injector of the new raw material concrete wall.  Thereby when the shield cutter 3 is passed in the portal excavated by the cutter 11, the projection 16 interferes with the entrance to damage it, and reversely the projection 16 is prevented from being damaged.

Title: Tape cassette and its box body
Inventor: SHINOHARA KOICHI
IPC: G11B23/087
Filed: 1988-02-15
Abstract: PURPOSE:To secure the reliability of high-packing-density recording even in a highly corrosive environment by providing trap layers whose corrosive property is equivalent to or higher than that of the magnetic recording layer of a magnetic tape housed in a tape cassette at part of the area in the vicinity of the magnetic tape stretched between both reels of the cassette. CONSTITUTION:Trap layers 23 and 24 whose corrosive property is equivalent to or higher than that of the magnetic recording layer 17 of a magnetic tape 16 are provided at part of the area in the vicinity of the magnetic tape 16 stretched between both reels. The corrosive gas entering and diffused into a tape cassette through gaps of the cassette is caught by the trap layers 23 and 24 when the gas makes a selective absorptive reaction with the layers 23 and 24. Since the successively entering gas flows toward the trap layers 23 and 24 because of the diffusion governed by the concentration gradient, the deterioration which takes place in the magnetic tape 16 can be maintained at such a level that at which the tape 16 is not practically affected even the magnetic tape 16 is used in the environment of a high-corrosive gas. Therefore, the magnetic recording layer 17 made of a metallic material can be used for high-packing-density recording even in a severe environment where a corrosive gas exists.
