摘要:
A digital camera has a display screen that improves an external design of the digital camera. The display screen is disposed on a front surface of the digital camera, which surface faces a subject when an image-taking optical system is directed to the subject. The display screen is capable of displaying an image such as a design image or a clock image. The digital camera is also capable of automatically displaying a through image when detecting a subject distance being shorter than a predetermined distance, i.e. a self-portrait is going to be taken. The digital camera is also capable of displaying an image based on personal image data so that a user can enjoy its external design.
摘要:
A process for preparing polyester pellets which involves blending polyethylene terephthalate and polyethylene isophthalate copolymer before solid state polymerization, the polyethylene isophthalate copolymer being composed of dicarboxylic acid constituent units derived from dicarboxylic acids containing terephthalic acid and isophthalic acid and diol constituent units derived from diols containing ethylene glycol and 1,3-bis(2-hydroxyethoxy)benzene, palletizing the blend and crystallizing the pellets.
摘要:
A process for preparing a polyhydroxycarboxylic acid having a weight average molecular weight of 50,000 to 1,000,000, which comprises a crystallizing step comprising (A) a step of heating pellets of a polyhydroxycarboxylic acid having a weight average molecular weight of 2,000 to 100,000 under stirring to a temperature from glass transition point or higher to a melting point or lower and heating until a defined result is attained, and (B) a step of heating the polyhydroxycarboxylic acid to a temperature of solid phase polycondensation reaction temperature, and a solid phase polycondensation reaction step of reacting the crystallized polyhydroxycarboxylic acid at an endothermic start temperature or lower of an endothermic peak as recognized upon temperature elevation analysis of the crystallized polyhydroxycarboxylic acid by using a differential scanning calorimeter.

摘要:
A method for producing a compound semiconductor device includes covering all but the top part of an electrode comprising a refractory metal or refractory metal silicide disposed on a compound semiconductor substrate with an insulating film, producing a photoresist which completely covers the insulating film at a first side of the electrode, the top part of the electrode, and at part of a second side of the electrode using the photoresist as a mask and removing the insulating film at the second side of the electrode, removing the photoresist, and ion implanting using the insulating film remaining at the first side of the electrode and the electrode as masks.
