Title: Output controlling system
Inventor: NAKAMURA HIDEAKI
IPC: G06F13/00
Filed: 1980-12-24
Abstract: PURPOSE:To perform distance transmission between a controller and an output equipment at low cost by passing the operation-state display signal and fault- state transfer signal of the output device through an AND gate, and by transmitting the AND result to the controller through a cable other than a data transmission cable. CONSTITUTION:When a printer 1 is powered up, a signal S2 goes up to a level H and while a signal S2 is at the level H when the printer has no fault, a signal S1 is at the level H when the printer is not in printing operation; and the H- level output signal S4 of an AND circuit 6 is sent to a controller 9 through a distant transmission system 7 and a cable 8. The controller 9 inputs print data DATA to a printer body 4 through a cable 10 by the signal S4, thereby performing prescribed printing operation. During the printing operation, the signal S1 is at a level L and each time one-line printing is done, it goes up from the L to H cyclically. If the printer is impaired or is powered down, the signal S2 or S3 goes down to the level L to cause the signal S4 to go down to the level L, so the controller 9 recognizes the occurrence of the fault of the printer to interrupt the tranmission of the data DATA immediately.

Title: Plasma address liquid crystal display panel, channel substrate assembly and manufacture thereof
Inventor: KEVIN J IRUSHISHIN
IPC: G02F1/1333
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent a contrast ratio of a display from lowering by providing coating of reflection preventive material on at least one side between a lower side of a cover sheet and an upper side surface of a channel substrate. SOLUTION: This panel is provided with the channel substrate 4 having a first surface and forming plural channels on this first surface, the cover sheet 6 arranged so as to cover the first surface of the channel substrate 4 and having the surface existing in an opposite relation with the first surface of the channel substrate 4 and the coating 6a of the reflection preventive material covering the surface of the cover sheet 6. Since the reflection preventive coating 6a is formed by the material such as a dielectric or glass, and is stuck surely to the channel substrate 4 and the cover sheet 6, the practical probability that they are separated from the channel substrate 4 or the cover sheet 6 doesn't exist. Then, since the reflection preventive coating 6a doesn't cancel light passing through a panel upward from a light source, the contrast ratio of the display isn't reduced.

Abstract: PURPOSE:To prevent erroneous operations, by not only generating sounds but also warning the movement of hands simultaneously with release inhibition when the strobe charging is not completed. CONSTITUTION:When a power source 6 is turned off while interlocking with a strobe switch 5, charging of a main capacitor 1 is started.
