Title: Bilateral transmitting/receiving circuit
Inventor: MATSUMOTO HIROSHIGE
IPC: H04L5/14
Filed: 1982-06-14
Abstract: PURPOSE:To discriminate the contents of communication on the way of a transmission line, by setting up driving current for two transmitting circuits on both the sides of the transmission line to different values to form four logical levels on the transmission line and making the four values correspond to all combinations of bilateral signals. CONSTITUTION:The transmitting/receiving circuits 30, 31 are connected to both the ends of the transmission line 32. When logical ''1'' is inputted from an input terminal 36 of the transmitting/receiving circuit 30, a driving circuit 33 sends driving current I0 to the transmission line through a terminal 38. When the transmitting/receiving circuit 31 inputs the logical ''1'' from an input terminal 37, driving circuits 34, 35 enter driving current I and combined driving current 2I is sent to the transmission line through a terminal 39. If the resistance values of terminal resistors 46, 47 are R1, the potential levels on the transmission line are four logical levels, GND, -IR/2, -IR, and -3IR/2 when both the driving circuits 33, 34 and 35 are off, when only the former circuits 33, 34 are on, when only the latter circuit 35 is on, and when both the circuits are on respectively. The potential levels are discriminated by a receiving circuit 48 connected on the way of the transmission line to detect transmitting and receiving signals.

Title: Shrink band, band reinforced cathode-ray tube and manufacture thereof
Inventor: YATOU TETSUOMI
IPC: H01J29/87
Filed: 1993-04-28
Abstract: PURPOSE:To install a shrink band in a specified position, and obtain an excellent explosion-proof effect by arranging a projection shape to support a metallic frame when a metallic frame band is installed around a panel skirt part of a cathode-ray tube by shrinkage fitting. CONSTITUTION:A U-shaped projection 12 projects in the outward direction in the end part opposite to the panel image surface side, and is formed in four places in the short side parts by fabrication. A reason why it is formed in these short side parts is that it is less influenced by deformation at shrinkage fitting time than that is formed in the long side parts. This projection shape has almost the same plate thickness with a shrink band 11. When the shrink band 11 formed in this way is heated and elongated, the shrink band 11 can supported by this projection shape part 12, so that an outer peripheral shape at heating and elongating time can be constituted in a similar shape to an outer peripheral shape of a panel skirt.
