摘要:
An image playback apparatus and in image recording apparatus are designed to permit image playback from a selected position in an image file recorded to a directly accessible memory, such as a magnetic disk. During recording of an image file, the user can designate one or more candidate playback start positions in the file, and corresponding pointers are stored as part of the image file. When the file is to be played back, the playback apparatus accesses the pointer(s) and allows the user to select playback from the corresponding position(s) in the image file. Also the playback apparatus can rewrite pointers in an image file, whereby the user can designate candidate starting positions for future playback of the file.

In an electric potential generating device, a source of an N type MIS transistor is mutually connected to that of a P type MIS transistor and also connected to an output terminal. A drain of an N type MIS transistor 54 is connected to a power supply voltage supply portion for supplying power supply voltage VDD, and a drain of the P type MIS transistor is connected to a ground. In addition, a substrate potential of the N type MIS transistor is a ground voltage VSS, and that of a P type MIS transistor 56 is the power supply voltage VDD. Thus, it is constituted as a source follower circuit for taking output out of the source. It is possible, by utilizing this electric potential generating device, to obtain a logic transformation circuit for stably switching between NOR operation and NAND operation.

A heterojunction bipolar transistor is fabricated by stacking a Si collector layer, a SiGeC base layer and a Si emitter layer in this order. By making the amount of a lattice strain in the SiGeC base layer on the Si collector layer 1.0% or less, the band gap can be narrower than the band gap of the conventional practical SiGe (the Ge content is about 10%), and good crystalline can be maintained after a heat treatment. As a result, a narrow band gap base with no practical inconvenience can be realized.
