Patent JP-S5696529-A (JP)
Title: Decoder circuit
Inventor: ISOGAI HIDEAKI
IPC: G11C11/416
Filed: 1979-12-27
Abstract: PURPOSE: To enable low bias, by providing a switching circuit with the base of a current absorption transistor which flows a bit current to the bit line.  
     CONSTITUTION: TR31 as a switching circuit is assembled in parallel with a current absorption transistor TR21 which flows a bit current IB to the bit line. When a bit selection input B is fed to the base of TR31, TR31 is on. It caused TR21 to turn on and a current IB flows to the corresponding bit line. Inversely, when the input inversion B' is fed to the base of TR31, TR31 is off, the base of TR21 is at ground potential to turn off TR21. The said current IB is switched depending on the input B or inversion B'. With such a circuit constitution, since switching circuits 31, 32 are located outside the bit line, the bias level given to the bit line is at about 0.8V corresponding to a diode drop, enabling low bias.

Title: Spectacles for stereoscopic vision
Inventor: HOTTA TAKESHI
IPC: G02B27/22
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for producing a special observed image, to produce the spectacles more close to design in comparison with the conventional ones, to use photopolymer material capable of dry developing, and to facilitate the production by using a volume phase type transmission type hologram. SOLUTION: This pair of spectacles is constituted of plane spectacles 1 and the spectacles 10 forming the volume phase type transmission type hologram. As to the hologram, interference fringe is recorded in photosensitive material by irradiating the surface of the photosensitive material from the same side with two luminous fluxes. Since the photosensitive material used in such a case is the photopolymer material capable of dry developing, recording is easily performed as designed and the production is facilitated. The hologram has angle and wavelength selectivity and its diffraction efficiency is about 100%, so that observation is performed in a state where unnecessary zero-degree light is prevented from getting in eyes.

Or, conductor patterns are provided on boards 6 and 7 and the boards are laminated with adhesive and through holes are formed in the lands 11 and 13 and plated. If conductors 8 and 10 are also composed of superconductors, at least their land parts are plated with Ag. If a grounding line is composed of a superconductor, as there is no voltage drop, the grounding circuit is equivalent to one point grounding. If a superconductor is applied to an electric source line, the electric source fluctuation of the whole circuit becomes constant and, if the superconductor is applied to the other part, a deformation of a waveform and a delay can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To adopt a rotary type for the washing brush of the water quality meter with simple constitution. SOLUTION: The lower end of a male screw part 115 is pressed against the upper end of a female screw part 117 by a leaf spring 105. When a shaft 106 rotates forward and the male screw part 115 rotates forward, the lower end of the male screw part 115 engages the upper end of the female screw part 117. When the forward rotation is carried on, the shaft 106 enters downward linear motion and the tip of the washing brush 2 is lowered until it comes into contact with light transmission windows 18 and 20 to scrape dirt off by rotation. When the forward rotation is further continued, the male screw part 115 and female screw part 117 are disengaged from each other.  At this time, the shaft 106 is energized upward through an upper E ring 112 with the elasticity of the leaf spring 105 and the male screw part 115 stops moving down while its upper end is pressed against the lower end of the female screw part 117. When the washing brush 2 is reversed in this state, the brush is put back in its original state through the reverse operation.

Abstract: PURPOSE:To improve driving force while decreasing input load by connecting the respective anodes of (n) diodes to the respective gates of (n) TRs, making a cathode common and connecting it to the gate of a low potential output side. CONSTITUTION:When both two input voltages IN1 and IN2 are at an L level, two transistors Tr20 and Tr21 are turned off, and a potential at a point N is corresponding to the potential of a VDD. The Tr20 and Tr21 integrally realize an NOR. On the other hand, when one of the voltages IN1 and IN2 is turned to an H level, diodes D1 and D2 realize a NOR circuit. During a transient period when NOR logic is changed to L, namely, when both or one of the IN1 and IN2 is changed to L, a current flowing to a pull-down Tr23 is increased, wiring capacity can be speedily discharged by a large load current -Lt, and an output voltage immediately falls from H to L. When both input voltages IN1 and IN2 are at the L level, the wiring capacity can be efficiently charged through a source follower transistor Tr11.

Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of each radio base station and to make the size of the station small by providing an antenna respectively to a master radio base station and each slave radio base station. SOLUTION: Radio base stations are classified into a master radio base station A having an electrooptic converter 14, a photoelectric converter 6, and a transmission reception circuit, and one or plural slave radio base stations B-1,...B-n each having only a transmission reception circuit, and an antenna 1(1-B1,..., 1-Bn) is provided to each radio base station A, and slave base stations B-1,..., B-n respectively. Only the master radio base station A is connected to a central base station C by optical fibers 7, 15, and the slave radio base stations B-1,...B-n are connected to the master radio base station A by coaxial cables. Thus, it is not required to provide a coupler between a high output amplifier 3 and the antenna 1 (or between each of high output amplifiers 3-B1,..., 3-Bn and each of the antennas 1-B1,..., 1-Bn).  As a result, the output level of each output amplifier is reduced by an insertion loss of the coupler and the power consumption of each radio base station is reduced and the size of each radio base station is made small.
