Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a program file generation method for executing an object program which requires a relocation operation in an environment where an operation system is absent. SOLUTION: A self-saver 6a4 continuously saves a self-loader 61a and an EXE file system application program 6a2, which follow after the self-saver on a memory image, on specified positions of a disk so that the self-loader 6a1 becomes the read object of a boot 2a. The self-loader 6a obtains various information from the boot 2a and loads the EXE file system application program 6a2 from the disk to a memory so as to start it. Thus, an object program which requires a relocation operation at the time of loading can directly be started in an environment where an operating system is absent by generating a program image which can immediately be executed by using the loader function of the operating system.

Title: Vertically peaking circuit of luminance signal
Inventor: NAKAHARA TOMOKO
IPC: H04N5/208
Filed: 1993-12-17
Abstract: PURPOSE:To generate an excellent video signal even at the time of displaying a video whose upper and lower parts are dropped out by using a signal obtained by replacing signals in the first and last horizontal periods of an original signal with a signal in one horizontal period just before and after a vertical video signal. CONSTITUTION:A first control signal (d) is a pulse which is at a High level only in one horizontal period just after the starting of a delay vertical mask signal (k) and a second control signal (f) is a pulse which is at a High level only in one horizontal period just before the starting of the signal (k). Then an AND circuit 18 outputs a primary differentiation signal (i) as it is when the signal (k) is at a High level and zero when the signal (k) is at a low level and turns OFF peaking in a vertical synchronizing period. In this way this circuit can generate a desirable video signal by preventing excessive shoot caused by level difference between a vertical synchronizing signal and the video signal from being given to the starting and finishing parts of the video signal and furthermore, turning off peaking in the vertical synchronizing period through the use of the mask signal.
