摘要:
A method of subjecting a silicon wafer doped with boron to a heat treatment in an argon atmosphere, wherein the argon atmosphere is replaced with a hydrogen atmosphere or a mixed gas of an argon gas and a hydrogen gas in a proper fashion, to thereby uniformize a boron concentration in the thickness direction of the surface layer of the silicon wafer doped with boron.
摘要:
A shaft furnace for melting copper solid into copper melt has been controlled by manual operation with reference to the actual storage quantity of the holding furnace so far. The burner air pressure of each zone of the shaft furnace is controlled by the actual storage quantity and the time change of it using Fuzzy Logic. The temperature of copper melt is adopted as another input signal. The proportion of burner air pressure of the zones is revised by the melt temperature. Automatic control basing upon the present invention decreases the fluctuation of storage quantity of the holding furnace.

This clear-coated stainless steel sheet includes: a stainless steel sheet; and a clear-coated film coated on either one or both of two main surfaces of the stainless steel sheet, wherein the clear-coated film contains a thermosetting resin composition (A) and resin beads (B) at a content in a range of 0.5 parts by mass to 4.0 parts by mass relative to 100 parts by mass of a solid content of the thermosetting resin composition (A), the thermosetting resin composition (A) includes an acrylic resin (A1) and a cross-linked curing resin (A2) composed of a blocked isocyanate resin and an amino resin which cross-link and cure the acrylic resin (A1), the acrylic resin (A1) includes one or more cross-linking functional groups selected from a hydroxyl group, a carboxylic group, and an alkoxy silane group, and the acrylic resin (A1) has a glass transition temperature of 30° C. to 90° C., and has a number average molecular weight of 3000 to 50000.
摘要:
An information processing apparatus includes a reservation unit reserving predetermined processing for a broadcast program, the predetermined processing being started in accordance with conditions corresponding to program information concerning the broadcast program; a processing unit starting the processing, reserved by the reservation unit, for the broadcast program in accordance with the conditions; and an acquiring unit acquiring the program information. The reservation unit obtains program information concerning another broadcast program for which the processing is reserved and which is to be broadcasted subsequent to the broadcast program, the program information being acquired by the acquiring unit, if the processing reserved for the broadcast program is started by the processing unit. The reservation unit changes the conditions of the processing reserved for the other broadcast program in accordance with the obtained program information concerning the other broadcast program.
