Title: Production of liquid crystal display element
Inventor: SHIMADA KENICHI
IPC: G02F1/1341
Filed: 1988-05-13
Abstract: PURPOSE:To reduce an amt. of a liquid crystal to be used by enabling injection and sealing of the liquid crystal, and to prevent a terminal part from contamina tion by the sealant by forming end faces of two substrates at a sealing port of the liquid crystal of a liquid crystal cell before sealing the liquid crystal as one same end face. CONSTITUTION:End faces of two substrates 1, 2 at a side where a liquid crystal sealing port 4 is formed in a liquid crystal cell is combined to one end face. The sealing port 4 is formed with a sealant 3 to extend to end faces of substrates 1, 2, further, a sealant stripping member 5 is formed at a part of a terminal forming substrate 1 where the sealant 3 at the extended liquid crystal sealing port 4 contacts. The liquid crystal sealing port 4 is sealed after charging liquid crystals to the liquid crystal cell from the sealing port 4. Thereafter, a terminal part is exposed by cutting an edge of confronting substrate 2 at the liquid crystal sealing port 4 side, and the sealang 3 at the extended sealing port 4 is removed simultaneously. Thus, a liquid crystal display element provided with a terminal drawn out in four directions is obtd., enabling injection and sealing of the liquid crystal, so the amt. of the liquid crystal to be used is reduced, and the terminal part is prevented from contamination by the sealant.

Title: Rudder
Inventor: MORI MASAHIKO
IPC: B63H25/38
Filed: 1981-07-22
Abstract: PURPOSE:To give a rudder hydrodynamic effect equivalent to that of a reaction rudder by providing the rudder trailing edge with a twist so as to meet the stream line in the propeller wake. CONSTITUTION:The cross-section of a leading edge 8 of a rudder 7 is made in a symmetrical wing form. As for a trailing edge, the upper part 9 above a propeller shaft 2 and the lower part 10 below the propeller shaft 2 are twisted respectively so as to meet flow vectors. The cross-section of the rudder is given a curved stream line form to obtain a kind of aerofoil form. Thus, a cumber is created between a straight line, connecting the leading edge to the trailing edge, and the curved line, and it produces functions as seen in a reaction rudder. In this connection, the amount of twist in both the upper (9) and lower (10) parts are mated with the flow vectors so that it is justified from the viewpoint of a hydrodynamics.

Title: Multiple terminal control system
Inventor: KAWAKAMI TOMOAKI
IPC: H04L12/423
Filed: 1979-09-07
Abstract: PURPOSE:To enable rapid and efficient data transmission control by an easy control system by providing a control line connecting respective terminal units in a loop separately from a communication circuit for data. CONSTITUTION:From multiple terminal controller 103 to adjacent terminal unit 1021, the control indication of ring-shaped control line 106 is sent being in state ''1'', i.e. communication permit state. Terminal 1021, when not to communicate with main computer 101, namely, no actuation request is sent, sends the control indication of state ''1'' to adjacent terminal 1022. When the actuation request is sent, on the other hand it communicates with computer 101 and, after the cmmunication ends, sends the indication of communication permission to terminal 1022 via control line 106. Thus, the control indication is sent to terminal 1021 again by way of terminals 1022-102n. Thus, the simple hardware constitution provides rapid and highly efficient data communication control between terminals and the main computer.

Title: Plasma address display device
Inventor: TOGAWA TAKEHIRO
IPC: G02F1/133
Filed: 1995-05-12
Abstract: PURPOSE: To prevent the crack of a dielectric sheet and the unequal display according to the slack of this dielectric sheet by setting the spacing distance between struts or between the partitions adjacent to these struts larger than the spacing distance between the partitions disposed in effective pixel regions. CONSTITUTION: The spacing distance between the partitionsions 5 in the effective pixel regions is set at an ordinary spacing distance. The struts 37 of the same structure and the same direction as those of the partitions 5 are disposed in non-effective regions and the spacing distance (b) between the struts 37 is set larger than the spacing distance (a) of partitions. The dielectric sheet 4 does not sag downward as the partitions 5 are formed at a fine pitch in the effective pixel regions even if the sheet 4 has the slack at the time of bringing the sheet 4 into tight contact with barrier ribs 33 by vacuum suction from a discharge pipe P.  On the other hand, the pitch between the struts 37 in the non-effective regions is wide and, therefore, the sheet 4 eventually sags downward between the struts 37 and the slack of the sheet 4 in the non-effective regions is absorbed and the sag is not produced in the effective pixel regions. The unequal gap of liquid crystals is thus lessened.

Abstract: PROBLEM TO BE SOLVED: To provide a position detection system which can detect the positions of a microphone and an input device containing the microphone just by adding a simple circuit by means of an existing constitution. SOLUTION: This system includes a detection signal output means which transmits the ultrasonic detection signals via a speaker SP with superimposition on or independently of the audio signals, a microcomputer which is connected to the detection signal output means and monitors the transmission timing of the ultrasonic detection signal, and a microphone 3 which collects the ultrasonic detection signals and outputs the reception timing of the ultrasonic detection signals to the microcomputer. The distance between the SP and the microphone 3 is calculated by multiplying the time interval set between the transmission timing and the reception timing of the ultrasonic detection signals by the sound velocity. Thus, it's possible to decide the relative position between the SP and the microphone 3 just by using a combination of an existing SP and the microphone 3.

Filed: 1990-05-02
Abstract: PURPOSE:To always supply almost a constant quantity of toner to a developing roller regardless of the toner quantity in a hopper by transmitting rocking motion from a rocking member by a toner supply member via an elastic member. CONSTITUTION:The toner supply member 3 is comprised so as to transmit the rocking motion from the rocking member 8 via the elastic member 8a. When smell quantity of toner exists in the hopper, a low load is applied form the toner 4 to the toner supply member 3, and a rocking driving force can be transmitted without deforming the elastic member 8a, therefore, the movable range of the toner supply member 3 can be increased, which surely transports the toner 4 at the bottom of the hopper 2 to the neighborhood of a roller 1. When a large quantity of toner exists in the hopper 2, the elastic member 8a is deformed by; the load on the toner supply member 3 received from the toner 4, and the movable range of the toner supply member 3 is decreased, and only the toner 4 at the upper part of the hoper is transported to the neighborhood of the developing roller 1. Thereby, it is possible to always supply a constant quantity of toner to the developing roller 1 regardless of the toner quantity in the hopper.
