Title: Positive characteristic thermistor heating element
Inventor: KAWAJIRI KEIJI
IPC: H05B3/14
Filed: 1991-06-21
Abstract: PURPOSE:To provide a positive characteristic thermistor heating element of a high reliability in which the temperature of a lead wire is not raised even though the positive characteristic thermistor heating element is heated, and no bad influence owing to the heating is generated, in a positive characteristic thermistor heating element used for a warm air heater, a dryer, and the like. CONSTITUTION:A hole 6a is provided between the calking part 6b and a tab 6c of a feeder terminal 6 of a positive characteristic thermistor heating element. As a result, the section area where the heat is transferred is reduced, and thereby the heat resistance is increased. As a result, the heat transmitted to a radiator 2 is cut off at the position of the hole 6a of the feeder terminal 6, and the heat transmission to a flat type connector 4 and a lead wire 5 is suppressed. Consequently, the temperature of the lead wire 5 is not raised too much, but lowered than the conventional device, and a positive characteristic thermistor heating element of a high reliability can be realized.

IPC: B32B27/20
Filed: 1991-04-04
Abstract: PURPOSE:To reduce a surface roughness by using a prepreg obtained by impregnating a fibrous base material with varnish mixed with a filler having smaller thermal expansion coefficient than that of resin and then impregnating the material with varnish not mixed with a filler. CONSTITUTION:A filler has smaller thermal expansion coefficient than that of thermosetting resin to be impregnated in a fibrous base material, and corresponds to an inorganic filler. As the thermosetting resin, epoxy resin, polyimide resin, etc., is used. As the base material, glass cloth, glass nonwoven fabric, synthetic fibrous cloth are desirable. The fibrous base material is first adhered and impregnated with filler-mixed varnish by coating or a coater, and then normally dried to remove solvent. Thus, much filler is existed in gaps of the material and in the vicinity of the surface. Then, the material is impregnated with varnish not mixed with filler to form a prepreg. Its surface roughness is small and its smoothness is excellent.

Title: Manufacture of silicon wafer
Inventor: HORAI MASATAKA
IPC: H01L21/26
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To eliminate deterioration in throughput and increase in cost, reduce the concentration of heavy metal contamination, and realize a low BMD density by carrying out lamp heating of a silicon wafer at a specified temperature, in manufacturing a silicon wafer from a silicon single crystal grown by a Czochralski method. SOLUTION: After a silicon wafer cut out from a silicon single crystal formed by a Czochralski method is lapped and etched, heat treatment is carried out at a temperature not lower than 1200 deg.C by a lamp furnace in a nitrogen atmosphere. For example, annealing is carried out by infrared radiation heating of a tungsten halogen lamp. Thus, in comparison with oxygen donor killer by a tube furnace at 650 deg.C for 30 minutes, the BMD (oxygen precipitate) density of the wafer treated by precipitation at 650 deg.C increases. In the wafer heat- treated at a temperature not lower than 1200 deg.C by the lamp furnace, the BMD density is significantly reduced, and a low BMD density may be realized even within a broad range of oxygen concentration.
