Title: Picture coding recording and reproducing device
Inventor: OKAMOTO HIROSHI
IPC: H04N19/136
Filed: 1993-03-29
Abstract: PURPOSE:To obtain the picture coding recording and reproducing device able to control a code quantity with less deterioration in picture quality when a picture is coded by variable length coding. CONSTITUTION:A comparison discrimination circuit 10 compares DCT coefficient data with data of a preceding frame or field to obtain picture correlation for each block. A code quantity integration circuit 12 obtains an accumulated code quantity after variable length coding and a code quantity control circuit 13 predicts whether or not the code quantity is finally an object code quantity or below. When it is predicted that the quantity exceeds the object code quantity, the code quantity is reduced by not transmitting data of a block with high picture correlation with the data of a preceding frame or field. At the reproduction side, a block whose data are not sent is replaced with the data of a preceding frame or field to obtain decoded data.

Title: Automatic means for starting or stopping spray work for chemical fluid-spraying vehicle
Inventor: SASAKI YASUO
IPC: B05B17/00
Filed: 1981-05-08
Abstract: PURPOSE: To eliminate the useless atomization of a chemical fluid, in a chemical fluid-spraying vehicle for fruit trees, by detecting a fruit tree with a photoelectric switch attached to the spraying vehicle, and automatically starting or stopping the spray of the chemical fluid from a spray nozzle.  
     CONSTITUTION: A photoelectric switch 9 radiates light from a projector 21,  modulated by a luminous diode 24 driven by an oscillating circuit (a), through a  lens. When a fruit tree comes in a detection distance, reflected modulated light  is detected by the photoelectric element 25 of a light receiver 22 and fed to a detecting part 23 where a modulation signal similar to an oscillation signal is taken out by a synchronized wave-detecting circuit (d). The modulation signal is fed through an integrating circuit (e) and a wave form shaping circuit (f) to drive the power transistor of an output circuit (g). The signal closes the relay  contact RA of an automatic control box 8 and excites a solenoid 12 to open a  valve. As a result, a chemical fluid is sprayed through a spray nozzle 11. When  the spray nozzle goes away from the fruit tree, the reflected modulated light  disappears and the spray work is stopped.

Title: Optical pulse generating method and equipment
Inventor: OZEKI YUKIHIRO
IPC: H01S3/10
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To generate large optical pulses whose width is small, by installing a Mach-Zehnder type intensity modulator and an electric field absorption type modulator which connect mutually in series a laser light from a single axial mode laser and synchronously operate. SOLUTION: A stationary laser light I0 emitted from a laser 11 is guided to a modulator 13 through an optical fiber 12. An output light I1 of a Mach- Zehnder type intensity modulator 13 which receives the stationary laser light I0 as an input light is guided to an electric field absorption type modulator 15, as an input light. When a sinewave signal 17 is applied to the modulator 13, it outputs the sinewave light I1 which is modulated synchronously with the signal 17. Thereby the stationary light I0 whose intensity is higher than that of the modulator 15 can be adopted as an input light of the modulator 13, so that the output of a sinewave light I1 which does not suffer from heavy attenuation is enabled.

Filed: 1989-03-24
Abstract: PURPOSE:To prevent malfunction by connecting half latch circuits in cascade to constitute a shift register, and operating each half latch circuit with at least 3 clocks of equal phase having a pulse width whose duty ratio is <=1/3. CONSTITUTION:A pulse width control circuit 14 is provided to narrow the pulse width of reference clocks B1, B2, B3 thereby forming shift clocks phi1, phi2, phi3 and the shift register is shifted by using the clocks.

The shift register is operated by using the clocks phi1, phi2, phi3 whose width is narrowed with the same period and same phase difference with the clocks B1, B2, B3. Thus, latching is applied when the input data of each latch circuit is made stable and no racing takes place even when the half latch circuit is in use.

Abstract: PURPOSE:To attain a safe contactless control circuit of AC power and to miniaturize the circuit by using a step-down transformer so as to isolate an operation switch and a power supply and utilizing a change in the voltage drop across a resistor connected to the primary coil so as to trigger an SCR. CONSTITUTION:When an AC voltage is applied to a control circuit through a load 9 and a switch is opened, an exciting current flows to a series circuit comprising a resistor 5, the primary coil 2 and a resistor 6, a voltage is applied to a gate of the SCRs 7, 8, but since the values of resistors 5, 6 are selected so as to give a voltage lower than the turn-on voltage, the SCRs are not triggered. When the switch 4 is closed, a short-circuit current flows, the impedance of the primary coil is decreased, the primary current is increased and the voltage drop of the resistors 5, 6 is increased, then one of the SCRs 7, 8 whose anode is positive is turned on and the SCRs are turned on at each half cycle of the power supply. In changing a variable resistor 13, continuous phase control is attained.
