Title: Pulse width expansion circuit
Inventor: SATOU MASAYA
IPC: H03K5/14
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit area by decreasing the number of delay elements used to obtain a required output pulse width. SOLUTION: A pulse width of an output signal DO is extended through OR arithmetic operation of delay element output signals N1-N3 of delay elements D1-D3. Furthermore, the delay element output signal N3 is fed back to a control circuit 10 to generate a cyclic pulse signal to extend the pulse width of the output signal DO. The pulse width of the output signal DO is effectively extended by circulating the cyclic pulse signal for a required number of times. Furthermore, the control circuit 10 is used to prevent the pulse width of the output signal DO from being extended more than as required by circulating the cyclic pulse signal for only the required number of times. Moreover, The control circuit 10 takes it into account that an input of an input signal DI is not interfered.

Title: File update system
Inventor: ITOU MICHIO
IPC: G06F12/00
Filed: 1984-04-26
Abstract: PURPOSE:To assure the normalness of one of two files despite a fault arises to an electronic computer during the update of a double structure file and also to confirm the normalness with a simple means, by providing the display of a update state and the update date/time point into said file as the control information. CONSTITUTION:When a file is updated, the control information 3 on an X surface file 1 is displayed during update. Then the data 5 on the file 1 is updated and the update date/time point is written to the information 3 to secure an update display. Then the control information 4 on a Y surface file 2 is displayed durgin update, and the data 6 on the file 2 is updated. Then the update date/time point is written to the information 4 to secure an updated display. When the update is discontinued due to a fault of an electronic computer, both informations 3 and 4 are read. Then it is decided that both surfaces are normal if the update state displays of both surfaces are already updated with the coincidence obtained between the update date/time points of both surfaces. While the file having the later update date/time point is decided normal if no coincidence is obtained between both update date/time points. Furthermore the file having the updated control information is decided normal in case one of both surfaces is already updated with the other surface out under update.

Abstract: PROBLEM TO BE SOLVED: To inform main body frame associated information to a player so that he/she can recognize it easily, by electrically connecting a main body frame associated controller to an image display controller, and displaying the operation condition of a gin body associated electrically driven device. SOLUTION: When a discharge shooting control circuit detects a trouble in a discharge shooting associated mechanism or another special mechanism, information thereon is fed through a command signal to a display control circuit 280. According to a command of a display CPU 282 issued based on the signal, image data of trouble information display (e.g. message display) corresponding to the trouble is extracted from a character ROM 285 by a VDP 283 and synthesized with a play associated image (e.g. variable display play image) displayed according to a command on the side of a generator control circuit, then a signal of the image is fed to an image display device 4. Accordingly the image is synthesized into a play associated image to thereby display the trouble information corresponding to the trouble.
