Title: Optical transmission/reception module
Inventor: TAKENAKA HIROSHI
IPC: H04B10/524
Filed: 1988-01-12
Abstract: PURPOSE:To obtain an optical data link with high transmission efficiency equivalent to that of full duplex system with a simple constitution by providing a means utilizing the time interval of a bit string of a reception signal to send one by one bit of bit string of a transmission signal. CONSTITUTION:A transmission signal from a terminal 1 is converted into an optical signal by a light emitting element 3 through a D latch 18 and a pulse width compression circuit 19. A reception signal is outputted to a terminal 9 and a clock generator OSC 20 through a light receiving element 7 and a preamplifier 8. The OSC in the reception of a reception signal outputs a synchronizing clock to the D latch 18. The output of a pulse width compression circuit is fed also to the preamplifier 8 and stops the operation of the preamplifier in the presence of the transmission pulse. The transmission signal passes to the pulse width compression circuit 19 to decrease the pulse width, and the signal is sent while utilizing the interval of the reception pulse train incoming with the compressed pulse width. Through the constitution above, the bidirectional transmission close to the full duplex system is attained without deteriorating transmission efficiency.

Filed: 1986-01-09
Abstract: PURPOSE:To use an output bus in common between systems having a different power voltage by inserting a switch between a power supply and a bulk of CMOS transistors (TRs) of series connection forming a high impedance circuit. CONSTITUTION:The high impedance circuit is formed by N-channel and P- channel TRs 1, 2 connected respectively to a power terminal 3 and a ground terminal 4, and when the TRs 1, 2 are turned off, an output point X reaches a high impedance. Switches 31, 32 are provided between the power supply and the bulk of the TRs.

Title: Electrochromic display element
Inventor: FUJIWARA RYOJI
IPC: G02F1/15
Filed: 1986-01-13
Abstract: PURPOSE:To obtain the element capable of effecting a patterning display having no ooze, without deterioration of the display quality by crystallizing surroundings of the display part of the reductive coloring layer. CONSTITUTION:The surroundings of the display part of the reductive coloring layer is crystallized. The crystallization range comprises the whole range except the display part 17 and the trimming part in the surroundings of the display part, for example, the surroundings of the display part 27. The EC layer is necessary to be an amorphous in order to color it. The crystallization of the EC layer does not bring a coloring, as the EC layer does not produce a proton whereby a reaction does not occur. Thus, when the surroundings of the display part (at least a part of occuring the ooze) crystallizes, the display having no ooze is obtained. And, the ooze of the oxidative coloring layer is prevented by patterning the oxidative coloring layers 13 and 23, and the lower display electrodes 12 and 22. The method of the crystallization is not specified, if the crystallization is effected with accuracy. For example, the prescribed method is preferably the laser-annealing method.
