摘要:
A p type semiconductor layer, an i type crystalline (polycrystalline, microcrystalline) photoelectric conversion layer, and an n type semiconductor layer are successively formed in the same plasma CVD deposition chamber. The p type semiconductor layer is produced on condition that the pressure in the deposition chamber is at least 5 Torr. Accordingly, a silicon-based thin film photoelectric conversion device having the p type semiconductor layer, the i type crystalline photoelectric conversion layer, and the n type semiconductor layer stacked on each other is manufactured. A method of manufacturing a silicon-based thin film photoelectric conversion device is thus implemented to produce a photoelectric conversion device having a superior performance and quality by a simple apparatus at a low cost and with high productivity.

An output control method includes the step of outputting a predetermined portion of data obtained by first direct memory access as last data of one line, checking whether the data obtained by the access includes data other than the last data, performing direct memory access again with respect to data at the same address as that in the previous access as start data of a line next to the previous line when it is determined that the obtained data includes data other than the last data, and outputting a predetermined portion of the data obtained by the second access as the start data. An output control apparatus for this method is also disclosed.

A polycrystalline silicon thin film having a hydrogen content of not more than 5 atomic %, which can be fabricated on an inexpensive glass substrate (3) such as soda glass or on a glass substrate (3) provided with a metal electrode or transparent electrode. The polycrystalline silicon thin film can be fabricated at such a tempereture by using multiple repetitions of a process comprising the fabrication of an amorphous silicon film, for example, by the CVD method, followed by exposure to a hydrogen plasma for set period of time.

There is provided an output apparatus comprising: a 1st memory to store the print information of the 1st color; a 2nd memory which stores the print information of the 2nd color and has the same address arrangement as that of the 1st memory; a CPU as a reading device for allowing the print information of the 1st and 2nd colors to be simultaneously read out of the 1st and 2nd memories synchronously with the print timing for the 1st-color print information; and a timing adjusting circuit for delaying the print timing for the readout 2nd-color print information than the print timing for the 1st-color print information by a predetermined time. The 2nd-color print information is temporarily stored into the 2nd memory consisting of an RAM or buffer memory and is read out therefrom after the print of the 1st-color print information. With the apparatus, the number of access reading times is reduced and the access timings for the memories can be easily adjusted by the single operation.

An information processing apparatus acquires identification information which specifies an interpreting program for interpreting a device control language, the specified interpreting program being operable in an external device connected to the information processing apparatus. It is discriminated whether a selected first control program corresponds to the device control language interpreted by the specified interpreting program. If it is discriminated that the selected first control program does not correspond to the device control language interpreted by the specified interpreting program, a second control program corresponding to the device control language interpreted by the specified interpreting program is selected from a plurality of control programs. Data is output to the external device using the first control program or, if it is discriminated that the first control program does not correspond to the device control language, the selected second control program.

A printing system includes a host computer and a printer. The host computer includes a memory which store process steps that are executable by a processor, and a processor. The processor executes the process steps stored in the memory (1) to divide encoded image data in a page of encoded image data into blocks, each block having a size which is less than a storage capacity of a buffer on a printer, and (2) to transmit the blocks of encoded image data to the printer. The printer includes a memory which stores process steps that are executable by a processor, and a processor. The processor executes the process steps stored in the memory (1) to store a predetermined amount of encoded image data in a buffer, (2) to control a printer engine to print images based on the encoded image data stored in the buffer, and (3) to store additional encoded image data, including blocks of the encoded image data, in the buffer in place of the encoded image data for which images have been printed.
