Patent JP-S62171461-A (JP)
Title: Power controller
Inventor: NISHIMURA HIDEKO
IPC: H02M1/08
Filed: 1986-01-22
Abstract: PURPOSE:To control the temperature and the moisture by an inexpensive method by providing a high permittivity capacitor having an electrostatic capacity change rate as a temperature sensor in a gate trigger. CONSTITUTION:An AC power source which supplies to a load 1 is controlled by a control rectifier Q1 to control the temperature of the load 1. A voltage applied to the rectifier Q1 is divided by a high permittivity capacitor CAF and a resistor R2, and the gate of the rectifier Q1 is controlled through a trigger element DIAC by the voltage at the midpoint. The capacitor CAF employs a capacitor having large temperature characteristic in electrostatic capacity change, and is thermally coupled with the load 1. The electrostatic capacity of the capacitor CAF is largely varied according to the temperature of the load 1, and the voltage applied to the element DIAC is varied. Accordingly, the ON/OFF time of the rectifier Q1 is varied to maintain the temperature of the load 1 constant.

Title: Optical waveguide connecting method
Inventor: TATSUTA MITSUHIRO
IPC: G02B6/26
Filed: 1984-01-27
Abstract: PURPOSE:To execute easily a low loss connection between each optical element, and also to execute it at a low cost by opposing two waveguides to be connected by placing a phase variation type photoconductive medium between them, and making a light pass through into it from cores of both the waveguides. CONSTITUTION:A waveguide 1 and 2 to be connected to each other are opposed so that the center axes (optical axes) of its core part 1-1 and 2-1 coincide roughly by an axial shift quantity of about several mum. In case that the two waveguides to be connected are both an optical fiber, a V-groove connector made of a reinforced plastic can be used. In case that one or both of the two waveguides 1, 2 to be connected are waveguide on a quartz substrate, this work can be executed easily by using a usual tremor base whose positioning accuracy is about 1mum. Subsequently, the connecting end faces of these waveguides 1, 2 are separated by a small distance (l), and this gap (l) is packed with a phase variation type photosensitive medium 3. Light for exposing the photosensitive medium is made incident from the non-connecting end face of the two waveguides 1, 2, and subsequently, a fixation of the photosensitive medium 3 is executed as the final step.

Title: Doppler radar
Inventor: UENO HISAYOSHI
IPC: G01S13/62
Filed: 1979-02-05
Abstract: PURPOSE:To accurately discriminate the direction of a target with a simple construction by processing predetermined difference of two sets of Doppler signals. CONSTITUTION:Two sets of Doppler signals produced upon detection of moving targets displaced at pi/2 or the like in phase by a phase shift controller 5 of a  Doppler detector 2 are generated from mixers 3, 4, respectively. One Doppler signal  is processed through a pi/2 phase shifter and through a differential amplifier 8, a  rectifier 9 and an integrating circuit 10 at the Doppler signal of the same phase.  Thus, the moving direction of the target can be accurately discriminated in response to the positive or negative of the Dc output averaged together with its speed  without comparing the phases of the two sets of the Doppler waves with a simple  construction.

Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To improve the encoding efficiency and to compress the images via a proper encoding method by detecting the redundancy of the input image data and selecting the encoding method based on the detected redundancy. SOLUTION: An image data input part 11 inputs the image data via an image data supply device 50. A redundancy detection part 12 detects the relative redundancy of the image data inputted from the part 11, and the detected redundancy is stored in a redundancy storage part 13. A redundancy read control part 16 gives a read instruction to the part 13, when the time code inputted via a time code input part 15 is set at the prescribed value. The part 13 reads out the redundancy, based on the received read instruction and transfers it to an encoding method selection designating part 14. The part 14 selects a proper encoding method based on the redundancy received from the part 13 and instructs the selected encoding method to an image-compressing device 100.
