Patent JP-H0632441-B2 (JP)
IPC: H04N9/73
Filed: 1984-09-11
Abstract: An automatic white balance control circuit includes a main photo-sensor (11) from which three primary color signals are derived (12), three external light sensing elements (21R, 21G, 21B) having spectral characteristics the same as those of the main photo-sensor (11), three capacitors (24R, 24G, 24B) for converting output currents from the three external light sensing elements to respective voltages, a voltage comparator (34) for comparing a voltage across at least the one capacitor (24G) corresponding to green light with a reference voltage (35), and three sample-and-hold circuits (27R, 28R; 27G, 28G; 27B, 28B) for sampling and holding voltages from the three capacitors (24R, 24G, 24B), respectively. Charging of the three capacitors by output currents from the three external light sensing elements, respectively, is started at the commencement of each cycle. When the voltage comparator (34) produces a compared output in response to the voltage across the one capacitor (24G) having become equal to the reference voltage, the charging is stopped and the voltages then present on the three capacitors are sampled and held by the three sample-and-hold circuits to thereby provide white balance control signals by which the level ratios of the three primary color signals derived from the main photo-sensor are controlled to be 1:1:1 thereby to adjust the white balance.

Abstract: In the process for making sodium persulfate by the reaction of ammonium persulfate and a base such as sodium hydroxide, sodium sulfate is formed as a by-product by the reduction of the persulfate by ammonia. By modifying the composition of the mother liquor, it is possible to separately crystallize pure sodium sulfate decahydrate from the mother liquor and thus maintain a sufficiently low sulfate concentration so that none crystallizes with the sodium persulfate product.

Abstract: A multiple access, spread spectrum communication system and method for providing high capacity communications to, from, or between a plurality of system users, using code-division-spread-spectrum communication signals. The communication system uses means for providing marginal isolation between user communication signals. The marginal isolation is provided by generating simultaneous multiple steerable beams; using an omni-directional antenna with polarization enhancement; using power control devices to adjust the output power for user generated communication signals either in response to their input activity level, or in accordance with a minimum allowable power for maintaining a communication link. The communication system can also employ a means for transmitting a predetermined pilot chip sequence contiguous with the code-division-spread-spectrum communication signals. In further embodiments the communication system employs a plurality of user terminals linked to each other or to other services through one or more terrestrial or satellite repeaters. Multiple satellite repeaters are operable in a new communication mode to obtain further gains in signal isolation.

Abstract: PROBLEM TO BE SOLVED: To save energy by suppressing the supercooling reheating when a dehumidification load is not present. SOLUTION: When a measured indoor humidity is lower than a set indoor humidity, a set level Tsp of supply air temperature is determined by optimization control. More specifically, the set level Tsp of supply air temperature is lowered by a specified level if the current exhibition capacity value of a reheater is lower than a minimum capacity set value otherwise the set level Tsp of supply air temperature is raised. Supercooling reheating is eliminated by preventing the set level Tsp of supply air temperature from lowering (P1'-P2'1 shown at (b), Pi"-P2" shown at (c)) down to a level (Tsp shown at (a)) for dehumidifying down to the set indoor humidity.

An active movement damping device provides for a field image stabilization in the telescope. The monolithic spring joint provides a spring action perpendicular to the optical axis with the springs being thickened in the axial direction toward the edge to improve supporting capability. Shock protection is provided in the region of the support pivot point and contains a releasable latching device. The active damping device consists of a magnet system movable relative to a current coil fixed to the housing. This current coil exhibits a nonlinear effect in order to axially adjust the damping constant. A magnet field sensor is located in the current coil and controls the current flow through the coils via a circuit so that a specific, time-limited change of the damping constant is possible.

Abstract: Optical fiber is provided with a periodically reversing spin while the fiber is pulled through a melt zone. A cooled region of the fiber downstream from the melt zone passes between a pair of opposed elements. The opposed elements are moved so that surface regions engaging the fiber move in opposite lateral directions relative to one another, thus spinning the fiber about its axis. The lateral movement of the engaged surface portions is periodically reversed to reverse the spin direction. The opposed elements may include belts or rollers, which can be tilted to orientations oblique to the longitudinal direction of the fiber.
