Title: Dc-dc converter circuit
Inventor: MORIMOTO TAKEKATSU
IPC: H02M3/155
Filed: 1979-07-18
Abstract: PURPOSE:To increase the width of a duty capable of changing an output, by using the duty based on the synthesized output of a reference oscillator and a monostable multivibrator circuit, which is triggered by the output of the oscillator and whose duty is variable, to change over a switching output unit. CONSTITUTION:A pulse voltage of a duty t1 is applied from the reference oscillator 5 to an OR circuit 7. A pulse voltage, the duty t2 of which starts just after said duty t1 and is stopped by the differentiation circuit C3, r7 of the reference oscillator 5, is applied from a monostable multivibrator 6 to the OR circuit 7. As a result, a switch- ing output unit produces an output of a duty t1+t2. If the output is low, it is detected and feedbacked through a voltage comparator 3 and a DC amplifier 4 to lengthen the duty t2 to heighten the output potential. For example, the duty t1 is varied within 10% and the other duty t2 is varied within 10-90% so that the output can be stably changed in a wide range.

The holes 4, 4 before threading are made by a punch 21 plus a die and the holes 4, 4 before threading are deburred 5, and the deburred cylindrical inner face 5a is threaded by rolling. Then it is so cut off that it contains dove tailed part 6, 6 at its root and tip. Next, it is bent around the cylindrical core, and a material 8 is finally formed to a pipe. This method facilitates the bending and enables continuous forming of plate and achieving of high productivity.

Title: Signal processor
Inventor: OOWAKI SHIGEHARU
IPC: G01S7/32
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent accurate detection from becoming impossible when the track of a target is an inclination nearly parallel to a distance or bearing axial direction due to Hough transformation only on the two-dimensional plane of a distance and a bearing. SOLUTION: The binary data of reception signals obtained by a threshold detector 52 are stored for several frames by a frame butter memory 53. A data processor 54 transforms the inputted binary data for indicating the track of the target to data projected on the three two-dimensional planes of the distancethe bearing, the distance-time and the time-the bearing. Image processors 55a, 55b and 55c image process the data projected on the three two-dimensional planes so as to take a value on a Hough space. The integrated point detectors 56a, 56b and 56c detect an integrated point inside the Hough space.  An integration and detection processor 57 discriminates the presence/absence of the integrated point inside the Houqh space detected in the integrated point detectors 56a-56c, integrates the detected integrated point to the line segment of the distancethe bearing-the time and detects a signal present on the line segment as the target.

Abstract: PURPOSE:To improve the heat absorbing efficiency of emitting infrared ray by condensing and emitting the infrared ray to a semiconductor substrate formed with an amorphous layer or a polycrystalline layer on the back surface of a substrate crystal via a  reflecting mirror and reaching the desired temperature only at the crystal and then forming an insulating film. CONSTITUTION:An infrared lamp 2 such as a high power tungsten lamp or the like is  mounted on a reflecting mirror 5 plated with Au or Pt on the surface, and a substrate  crystal 2 supported to a transparent quartz supporting base 3 and sealed in a transparent quartz tube 4 is installed in the inner space. Since the infrared ray heating converts and uses the light energy of the infrared ray into thermal energy of heating the substrate, the substrate preferably has large absorption of the light of particularly 0.5- 2mum in wavelength to efficiently convert the ray to the thermal energy. In order to  further improve the temperature rising and falling characteristics to suppress the decomposition of the compound semiconductor as low as possible, an amorphous layer 2'  is formed on the insulating film forming substrate 2. This layer 2' has large conversion  efficiency of infrared light to heat as compared with the single crystal state of the  compound semiconductor in the absorption coefficient to the wavelength of approx.  1-2mum.
