Using a metal mold (20a) consisting of a convex mold part (21a) and a concave mold part (22a), a molding material (14) is placed between a pair of coating films (12), and after claming, the molding material (14) and the coating film (12) are heated and molded to make a biodegradable expanded molded article, and at the same time, the coating film (12) is softened and pressure-bonded to a surface of the biodegradable expanded molded article. An exhaust hole (31a) and (32a) are provided on the convex mold part (21a) and the concave mold part (22a), respectively. At the time of heating and molding, gaseous matter existing between the coating film (12) and a surface of the metal mold (20a) is discharged out of the metal mold (20a) through the exhaust holes (31a) and (32a). Accordingly, it is possible to provide a method and a mold to manufacture a biodegradable expanded molded article easily and with excellent accuracy of dimension, having enough strength, enough water resistance, very excellent biodegradability and excellent surface smoothness even if the biodegradable molded article has a complicated shape.

A bowl-shaped container (10a) which is as a biodegradable molded article adheres a coating film (12) mainly made of biodegradable plastic and having at least hydrophobicity to the surface of the main body (11a) of the container mainly made of starch. The main body (11a) is molded through steam expansion of a slurry or dough molding material containing high-amylose starch and water, or a slurry or dough molding material containing starch, polyvinyl alcohol and water. For these reasons, it is possible to accomplish sufficient strength and at least sufficient water resistance, to exert a very excellent biodegradability and further to provide a biodegradable molded article having excellent moisture absorption strength mainly made of starch even if the biodegradable molded article has a complicated shape.

Independent power supply systems are provided for a peripheral circuit other than a column decoder, an array-relevant circuit, and a column decoder respectively, so that a peripheral power supply voltage, an array power supply voltage, and a column decoder power supply voltage generated independently of each other are supplied to the peripheral circuit, the array-relevant circuit, and the column decoder as an operating power supply voltage, respectively. Preferably, the column decoder power supply voltage during normal operation is set as an intermediate voltage between the peripheral power supply voltage and the array power supply voltage. Thus, an array configuration suitable for driving a transistor with a low voltage in order to achieve lower power consumption can be obtained.

摘要:
In a case where maintenance operations are sequentially performed while the status of a computer peripheral device is determined, the status of the computer peripheral device may not be clearly determined, and it may be difficult for a user to perform the next operation. In a setup operation of a printer 1050, the status of the printer 1050 such as existence/absence of ink cartridge or ink charging operation is detected on the side of computer 1010 via a printer driver 1073. On the other hand, a setup guide program 1075 determines the progress of the setup operation from the status change of the printer 1050, and sequentially displays images showing operation procedures in correspondence with the progress. Accordingly, it is not necessary for the user to perform the setup operation while determining the status of the printer 1050, and the user can smoothly perform the setup operation.
