Title: Method and apparatus for measuring urea
Inventor: IKEDA HISAYUKI
IPC: G01N33/483
Filed: 1981-09-30
Abstract: PURPOSE:To measure urea quickly and accurately free from error factors by adjusting the pH of a carrier solution to a desired value utilizing electrolytic reaction in an electrolytic cell. CONSTITUTION:With the driving of a pump 4, an absorbing liquid 2a (HNO3) is recovered into a container 1a flowing through a passage 10a while a carrier solution 2b is dumped into a container 1c flowing through a passage 10b. After injected into the passage 10b from an injector 5, a given amount of material to be measured is carried to a solidifying enzyme 6 with the carrier solution which urea in the material undergoes an oxygen reaction and NH<+> and HCO3<-> thus formed reaches a cation exchange membrane tube 7a. When a specified voltage is applied between cathode 7b and an anode 7c frorm a power source 7d, a saturated solution 7e of sodium salt raise pH value of the carrier solution 2b under an electrolytic reaction. NH4<+> is converted into NH3 and reaches a chamber 8c in a flow cell 8h. Then it transmits through a thin film 8a reaching a chamber 8b and absorbed by the absorbing liquid. The conductivity of NH4NO3 formed is detected with an electrode 9a and then, the concentration of urea is indicated on conductivity meter 9b by computation thereof.

IPC: G02F1/1343
Filed: 1987-06-23
Abstract: PURPOSE: To enable the impression of a driving voltage from one transparent substrate side by providing voltage impressing terminals only to one of the transparent conductive layers on the surfaces of a pair of transparent substrates and electrically insulating the one transparent conductive layer thereof, thereby forming two regions where a prescribed potential difference is imparted.  
     CONSTITUTION: A voltage is impressed via the voltage impressing terminals 210, 220 on one 2b of the opposed transparent conductive layers 2a, 2b of a liquid crystal display element and the voltage is not impressed from the outside on the other one 2a. The one 2b on the side where the voltage is impressed has the two regions 21, 22 where the prescribed voltage is impressed. The electric charge of the polarity reverse from the polarity of the charge generated in the two regions 21, 22 by the impression of the voltage on said regions is induced by electrostatic induction in the transparent conductive layer 2a of another side opposite respectively to the above-mentioned two regions. The voltage is impressed on the liquid crystal material between the transparent conductive layers facing each other by such electrostatic induction. The impression of the voltage only from one side of the transparent electrodes is thereby enabled without requiring a voltage impressing part such as transfer.

Title: Synchronizing detection circuit
Inventor: KATOU SADAMIKI
IPC: H04N1/40
Filed: 1981-09-30
Abstract: PURPOSE:To eliminate the effect of phase inversion of a carrier wave, by separating an output terminal of a phase comparator of a phase locked loop of a period detecting circuit from an input terminal of an integrator, at the expectation of phase inversion of the carrier wave of a reception input signal. CONSTITUTION:During a period when the phase inversion of a carrier wave is expected, i.e., blanking period, an interruptor 17 is made nonconductive with a blanking signal 18. Then, an integrator during the blanking period has no input and its output is kept to a voltage just before the blanking period. Thus, the phase of an output signal of a voltage controlled oscillator 8 is fixed and not affected with the phase inversion of the carrier wave. Thus, an output signal 9 of the oscillator 8 can be used for demodulation as a direct reproducing carrier wave. Further, the signal of the oscillator 8 has equal frequency to that of the carrier wave component and is synchronized with the component through the feedback control of a phase locked loop 10.

Title: High speed continuous approximation register in analog-to-digital converter
Inventor: JIMII REI NEIRAA
IPC: H03M1/00
Filed: 1988-06-24
Abstract: PURPOSE: To attain the high speed operation of a continuous approximate register by providing a data latch and a related gate circuit, and escaping inside competition by delaying transmission. CONSTITUTION: Continuous approximate comparator data are inputted to a terminal 6, and inputted prescribed data latches 11-1-11-N according to each level. Also, when a prescribed logical output level VDD is inputted to a shift register bit 13-1, and a signal clock inputted to a terminal 15 is inputted to bits 13-1-13-N, the output is inputted to the L terminal of the corresponding latch 11. The latch 11 delays the inputted data, and the data are outputted and inputted to a corresponding AND gate 12(12-1-12-N) with the input of the terminal L. Here, the output of the bit 13-1 is repeated until the N pieces of bits 13 are forwarded, and it reaches the bit 13-N. As a result, the exact continuous approximation with a smaller number of approximation than an input signal VIN can be obtained.  The gate 12 is provided with an FF circuit function, and the delayed data are outputted through a terminal 8. As a result, inside competition can be escaped, and the number of approximation can be decreased. Thus, the high speed operation of a continuous approximate register 7 can be attained.

CONSTITUTION:Recording/reproducing system heads 401, 402, 403 record/ reproduce plural picture signals, and in synthesizing pictures, at first three heads start reading of the R, G, B picture signals. Then the signal representing the head of the R, G, B picture signals is detected and when they are detected at the same time, the three heads read the head of each picture signal at the same time and each picture signal is synthesized through decoding. That is, the R, G, B picture signals are decoded and rewritten respectively and synthesized by a picture synthesizer and printed out by a printer section 1000. The plural pictures are synthesized accurately and the cost is reduced by synchronizing the plural picture signals and reproducing them in this way.

Abstract: PROBLEM TO BE SOLVED: To prevent jitter included in a video signal from appearing as fluctuation in a digital output by detecting unsharpened waveform of an analog image signal. SOLUTION: A video signal fed to an input terminal 1 is fed to a delay circuit 12 and a subtractor circuit 14, and the video signal via the delay circuit 12 is fed to a delay circuit 13 and a synthesis circuit 16.

The unsharpened signal is differentiated by the differentiation circuit 15 and the resulting signal is synthesized with the video signal via the delay circuit 12 at a synthesis circuit 16 as a corrected unsharpening signal.  Thus, the video signal waveform-shaped by a waveform shaping circuit 11 is fed to an A/D converter 2, in which the signal is converted into a digital signal based on a sampling clock fs fed to an input terminal 10.

Title: Two-component developer for electrophotograpy
Inventor: OKADA JUNKO
IPC: G03G9/097
Filed: 1986-07-05
Abstract: PURPOSE:To stabilize the electric charge quantity of a toner by subjecting a ferrite carrier to a surface treatment by a fluorine surface active agent and positive charge controlling agent. CONSTITUTION:The surface of the ferrite carrier particles is coated with the fluorine surface active agent and positive charge controlling agent. The ferrite carrier, the electric resistance of which is generally 6X10<4>-2X10<7>OMEGA.cm, more particularly 2.5X10<5>-1.5X10<7>OMEGA.cm volumetric resistance is used. The humidity dependency of the ferrite carrier is extremely high; for example, the volumetric resistance decreases to a fraction of several tens or a fraction of several hundreds at 80% humidity as compared to 40% humidity and since the tendency to the decrease is particularly larger with the carriers of the higher resistance; therefore, the surface coating treatment of the ferrite carrier is executed. The humidity dependency is thereby eliminated and the adsorption of water molecules is prevented, by which the electric charge quantity of the toner is stably maintained.
