Title: Liquid crystal display element
Inventor: YAMAGUCHI TOSHIAKI
IPC: G02F1/1339
Filed: 1994-04-22
Abstract: PURPOSE:To provide the liquid crystal display element of high quality by allowing the front end of a second substrate, where a charging port is provided, to project from the front end of a first substrate to prevent the static electricity due to foreign matters from being applied to the element. CONSTITUTION:First and second substrates 1 and 6 are stuck to each other by a seal material 7. In this case, the seal material 7 forms a liquid crystal layer 9 between substrates 1 and 6 except a part to be a charging port 8 in one end face sides of substrates 1 and 6. The first substrate 1 is cut in a cutting position 25 by a scrub or break method to form a first substrate 1a where the front end of the face on the side of the charging port 8 is on the inside of the front end of the second substrate 6. Since the front end of the second substrate 6 where the charging port 8 is provided projects from that of the first substrate 1a in this manner, a liquid crystal saucer and scanning lines 13 are not brought into contact with each other in the liquid crystal charging stage and the stopper of a cassette and scanning lines 13 are not brought into contact with each other in washing and drying stages; and thus, foreign matters are hardly brought into contact with scanning lines 13.

Title: Temporary storing circuit of josephson effect element
Inventor: NAKAGAWA HIROSHI
IPC: G11C11/44
Filed: 1981-06-02
Abstract: PURPOSE:To temporarily store an input signal, and also to erase a stored signal, by using  Josephson effect elements. CONSTITUTION:As for a Josephson effect element J1 being in a superconductive state, to which positive and negative constant DC bias currents are supplied, when a set input current pulse is injected from a set input terminal S, the Josephson effect element J1 switches it, generates an output current to a load resistance RL, and this state is held. Subsequently, when a reset current pulse is injected from a reset input terminal R, a resetting Josephson effect element J2 switches it once, and as a result, a reverse current flows to the Josephson effect element J1, and the Josephson effect element J1 is transferred to a superconductive state from a high resistance state. When the Josephson effect element J1 becomes a superconductive state, the Josephson effect element J2 is also transferred to a superconductive state, therefore, the circuit is returned to its initial state.

Filed: 1990-04-02
Abstract: PURPOSE:To set an appropriate stop value fitted for the optical image of an object by detecting a brightness dispersed area included in the optical image which is formed based on an image signal outputted by an image pickup means and controlling the opening degree of the diaphragm of a diaphragm means so that the dispersed range may be maximum. CONSTITUTION:A dispersed value detection part 22 detects the lightness and darkness dispersed range in a brightness condition in a specified photometric area based on the image signal corresponding to the specified photometric area read out from an image data memory 19 to a control part 11. Then, the control part 11 allows an arithmetic comparison part 24 to compare a brightness dispersed value which is detected last time and previously stored in a dispersed value data storage part 23a with a brightness dispersed value which is detected this time by the means 22 and judges the relation between them. Namely, the opening degree of the diaphragm 12 is previously controlled so that the brightness dispersed range of the optical image of the object formed by being made incident on a solid-state image pickup element 16 may be the maximum range. Thus, image pickup processing with vivid contrast is performed in the optimum exposing state.

Title: Elevator landing control device
Inventor: MORINO MASAMI
IPC: B66B1/40
Filed: 1994-03-30
Abstract: PURPOSE:To allow elevator passengers to have a stable time always and have the sense of ease at elevator landing by executing the stop operation when the actual speed has become below the predetermined value and the preset time elapsed. CONSTITUTION:An elevator control device 12 is equipped with a timer 124 for restricting the landing time. When the actual speed has become under a low value V and a certain period of time T1 passed from the sensing point P2, the control device 12 judges that the landing is completed and executes the stopping operation. Thus the zero-speed control operation by the low value V is stepped at the time T1 forcedly, and passenger(s) is given a stable time at landing and a sense of ease.

Abstract: PROBLEM TO BE SOLVED: To provide a printing apparatus good in work efficiency. SOLUTION: When a printing head 72 is opened by oscillating a head frame 76 in a counterclockwise direction from such a state that the printing head 72 is closed, a pin 104 comes into contact with the lower edge of a lever 98 and the recessed part 98A of the lever 98 is detached from a pin 102 and the pin 104 pushes up the lever 98 to revolve the same clockwise.

Title: Multi-port memory controller
Inventor: EURA FUMIAKI
IPC: G06F13/18
Filed: 1987-04-09
Abstract: PURPOSE:To reduce the overhead time needed for arbitration control by using plural control means wet at each port and a circuit abnormality monitoring means and performs the sampling of an application request without using a fixed clock. CONSTITUTION:When an application requesting line 1a is set at a low level after an access is applied to a common memory against an application request, a pulse restart F/F 5a is set at the edge of the line 1a. Then a pulse circulation F/F 4a is set. Thus an application requesting sample F/F 3b of the next stage is started for restart of the pulse circulation. When the circulation pulse extinguishes by some reason while the application requesting line groups 1a-1d are all kept at low levels, an abnormality occurrence monitor up-counter 8 is not reset any more. Thus an overflow is produced and the circulation of the pulse is started by the same operation as that carried out when a power supply is applied. In such a way, the arbitration control is performed at high speed for a multi-port memory with circulation of the priority.

IPC: G06F11/28
Filed: 1988-04-06
Abstract: PURPOSE:To correctly trace the practical movement of a micro-ROM by inputting an address of the micro-ROM to a storage circuit simultaneously with its output. CONSTITUTION:When a microprogram test control signal 5 is activated, a RAM address register 3 is set up to a certain value. When a certain microinstruction is executed, a micro-ROM address register 1 is set up, the micro-ROM 2 is accessed and a micro-ROM address is written in a RAM 7 through a buffer 4 simultaneously with the access. The register 3 is driven synchronously with a micro-ROM address register control signal 9 to successively increase the address of the RAM 7 and input and store micro-ROM addresses into the RAM 7. Thus the practically movement of the micro-ROM in a semiconductor integrated circuit can be correctly traced.

Abstract: PURPOSE:To obtain the high-purity substance by converting biphenyldicarboxylic acid into a dialkali salt, adding a water-soluble organic solvent to the resultant aqueous solution, depositing the dialkali salt, separating and liberating the formed salt. CONSTITUTION:An alkali and water are added to crude biphenyldicarboxylic acid(BDCA) to provide an aqueous solution of a dialkali salt and a water-soluble organic solvent is then added thereto to provide an aqueous solution of the dialkali salt. Thereby, solubility of the dialkali salt in water is reduced to deposit the dialkali salt. The separated crystals are then dissolved in water and a mineral or organic acid is subsequently added to afford the high-purity BDCA. A solvent (e.g. acetone) having >=100g/100g-water solubility in water at 20 deg.C and a lower boiling point than that of water with a great difference in the boiling point therefrom is preferred as the water-soluble organic solvent in aspects of recovery. The amount thereof used is preferably such that >=50% dialkali salt is deposited. The high-purity BDCA is useful as a raw material for polymers.
