Title: Frequency tunable distributed bragg reflection-type semiconductor laser
Inventor: MURATA SHIGERU
IPC: H01S5/0625
Filed: 1986-09-16
Abstract: PURPOSE:To obtain frequency control extending over a wide range and FM characteristics at high speed simultaneously by biassing a distributed Bragg reflection section in the forward direction capable of injecting carriers, biassing at least one part of a phase control section in the opposite direction and controlling an effective refractive index by an electro-optic effect. CONSTITUTION:A DBR section 30 is biassed in the forward direction and an effective refractive index can be controlled by injecting carriers while a phase control section 20 is reverse-biassed, the phase of beams propagated through an active section 10 is changed effectively by the alteration of the effective refractive index by an electro- optic effect, and the oscillation frequency of the beams can be varied. The change of the effective refractive index at that time is made smaller than the case of carrier injection by approximately two figures while response characteristics up to high frequency are acquired when the voltage of the active section 10 is modulated and oscillation frequency is modulated. Accordingly, frequency extending over a wide range is controlled by controlling inrush currents in the DBR section 30, oscillation frequency is tuned previously at a desired value, and the voltage of the phase control section 20 is modulated, thus simultaneously realizing the control of frequency extending over the wide range and FM at high speed.

Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To attain the high speed of a data writing operation under a low voltage by equalizing the pair of bit lines selected by being synchronized with a column selection signal at the time of writing data to memory cells being on the column selected with the column selection signal via the sense amplifier provided in the column. SOLUTION: At the time of writing data, a bit line pair control circuit 20 equalizes the pair of bit lines BL1, the inverse of BL1 by inputting a control signal WT and a column selection signal CL1. The potential of the pair of bit lines BL1, the inverse of BL1 becomes roughly one half a power source voltage Vii by this equalization and a sense amplifier 13 is not required to perform the conventional inversion write having the amplitude of the power source voltage Vii but may perform a charging and discharging having the half amplitude of the power source voltage Vii. Thus, the driving capacity of the sense amplifier 13 is made small and it is made possible to write data with a small signal amplitude being on local data busses LDB, the inverse of LDB and, then, the data writing operation is performed at high speed.

Title: Current control method for switching direct current to alternating current in heavy-current level, and controller thereof
Inventor: KITAZATO HIROSHI
IPC: H02M1/06
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient inexpensive heavy-current supplying power source by providing a zero-level clamping section to a circuit with an inexpensive thyristor which does not have self-extinguishing function of an AC switching section. SOLUTION: A circuit is provided with a zero-level clamping section 9 between an DC output section 2 and an AC converting section 3 and quickens disconnection of a large-current supplying power source by short-circuiting the current of an AC output-side circuit, through the means of the clamping section 9 with skillful utilization of the constant difference of L1>L2, when the power source is disconnected. After the power source is disconnected, the circuit quickens conduction of another element by utilizing a residual current (J) flowing between the DC output section 2 and the clamping section 9 by releasing the clamping section, immediately after or a fixed period after the DC output section 2 is turned on.  As a result, since the residual current (J) can be utilized more effectively, the efficiency of the power source can be improved, and since a thyristor is adopted as an inexpensive element which can cope with large currents although the thyristor has no self-extinguishing function, the cost of the power source can be reduced drastically as a whole.

Title: Non-porous moisture permeable and waterproof film and its manufacture
Inventor: FURUTA TSUNEKATSU
IPC: B29L7/00
Filed: 1985-10-01
Abstract: PURPOSE:To enable the titled method to possess high moisture permeability though the titled film is non-porous and a fine hole forming agent is not used, by stretching a polyamino acid urethane resin film in an unstretched state in a monoaxial or biaxial direction. CONSTITUTION:The titled film is a resin film composed of polyamino acid urethane resin and it is stretched unidirectionally at least. In addition to the above, its manufacture is performed based on a method wherein an unstretched resin film composed of the polyamino acid urethane resin is stretched 1.5-13 times under the temperature terms of 60-150 deg.C and heat treatment is performed within a temperature range of 100-160 deg.C at a take-up ratio of 0.9-1.0 in a gaseous atmosphere whose temperature is higher than that at the time of stretching. It is desirable to make a film of 10-100mum in thickness from a viewpoint of operational properties to stretch an unstretched PAU resin film. With this construction, a moisture permeable and waterproof film having the same degree of moisture permeability as a porous film is obtained through it is a non-porous polyamino acid urethane resin film.

Filed: 1984-10-18
Abstract: PURPOSE:To obtain a thermal recording material having good stability and high sensitivity as well as soft picture quality of lesser color-forming unevenness even during the facsimile transmission period by a method in which a thermal color-forming layer composed of a leuco dye and a developer is provided on a supporter, and a high polymer protective layer containing a specific ester compound is formed on the thermal color-forming layer. CONSTITUTION:A thermal recording material is obtained by forming a thermal color-forming layer on a supporter (e.g., paper, plastic film, synthetic paper, woven fabric sheet, etc.) by coating a coating liquid containing thermal color- forming layer-forming components on the supporter and then drying it. A coating liquid containing a protective layer-forming components including an ester compound of the formula (I), where R is a C1-C10 alkyl and X and Y are differently or incidently H, a lower alkyl, or a halogen atom, is coated on the thermal color-forming layer and then dried to form a protective layer. The preferred amount of the compound of the formula (I) to add to the protec tive layer is 5-l50 wt.%. The addition of 5 wt.% of less is less effective but 50 wt.% or more deteriorates the barrier property of the high polymer protective film.

Abstract: PURPOSE:To perform the signal processing of plural chrominance signals with the minimum circuit constitution by selecting one signal sequentially from each chrominance signal from an image sensor which outputs plural chrominance signals simultaneously, performing a signal processing on a selected output signal, and outputting it as a digital signal. CONSTITUTION:The image sensor 1 outputs an R signal 101, a G signal 102, and a B signal 103. A selection circuit 2 selects one chrominance signal sequentially from the chrominance signals 101, 102, and 103, and outputs it as an output signal 201. The output signal 201 is converted to the digital signal at an A/D conversion circuit 31, and its shading distortion is corrected at a shading correction circuit 32, then, is outputted as an output signal 301. Since each chrominance signal is multiplexed at the stage of an analog signal and the processing of A/D conversion and the shading correction, etc., is executed by one system of processing circuit, it is possible to perform the signal processing of the plural chrominance signals with the minimum circuit constitution.

Title: Sewage treatment device
Inventor: KITAGAWA MIKIO
IPC: C02F3/08
Filed: 1985-10-03
Abstract: PURPOSE:To continue operation in a uniformly fluidized state by discharging the living carrier particles to which living films are excessively and thickly stuck from a fluidized bed type reaction vessel to a liquid cyclone, adjusting the thickness of the stuck films to a required thickness and returning the particles to the reaction vessel. CONSTITUTION:A means 3 for discharging the living carrier particles is opened near the boundary of the fluidized bed 2 of the fluidized bed type reaction vessel 1 which contains the living carrier particles and treats sewage biochemically. The living carrier particles emitted from the means 3 are accepted in the liquid cyclone 4 having an inverted circular cone shape in the lower part and a pump P is operated to stir the particles by the swirling flow of the liquid, thus thinly adjusting the thickness of the living films sticking to the particles. The carrier particles from the liquid cyclone 4 are returned to the reaction vessel 1 by a return means 5. As a result, the apparent specific gravity of the living carrier particles constituting the fluidized bed is made uniform and the operation can be continued in the uniformly fluidized state. The treatment is made possible even under high load and since the replenishment of the carrier particles is not required, the running cost is reduced as well.

IPC: H04L13/10
Filed: 1983-11-21
Abstract: PURPOSE:To reduce the load and to improve the data processing efficiency with a data transmission control system by using a delay means to inform that 2 transmission buffers empty to a processor by a single interruption. CONSTITUTION:When the transmission is through with characters set to a unit transmission buffer, a circuit control part 4 activates an interruption signal IRQ showing the end of transfer of a character. Then a counter 3 counts the circuit clocks supplied from a clock generating part 5. The count output is turned into an interruption signal to be applied to a CPU1 through a latch 2. Then the latch 2 is reset via a control register 6 and at the same time the next transmission data is written to two transmission buffers of the part 4. In such a way, the transmission interrupting frequencies to the CPU1 are considerably reduced and therefore improve the data processing efficiency.
