IPC: G01S7/40
Filed: 1988-02-05
Abstract: PURPOSE:To evaluate and analyze a radar data processing system in a shorter time when before by providing algorithm for calculating dummy radar data by approximation and an applied dummy signal generating device. CONSTITUTION:A radar parameter input processing circuit 3 performs the input processing of the installation positions and covering areas of respective radars and the rotating time (scan time) of antennas so as to analyze how respective radars acquire target airframe data. This method performs sampling at each scan time as primary processing. In this case, the distance Rn from a radar is calculated from Rn={(xn-x0)<2>+(yn-y0)<2>}<1/2>. Necessary data are data only in the radar covering areas, Rn is calculated, and then it is decided whether the target is inside or outside the radar covering area. The azimuth angle thetan corresponding to cross-ruled north (true north) is easily extracted from the position of the target airframe and the center coordinates of the radar by using a trigonometric function.

Filed: 1990-02-05
Abstract: PURPOSE:To execute picture discrimination accurately by sampling a picture data outputted from a scanner while an original area transferred actually onto transfer paper is scanned so as to discriminate the picture. CONSTITUTION:A picture data outputted from a scanner 1 is sampled for a period only when a scanner 1 scans an original transferred actually on the transfer paper in a data sampling section 11. Then the picture data sampled in this way is fed to a picture discrimination section 16 and the kind of the picture or the like is discriminated based only on the picture data. Thus, a fact of using a picture data for an original or other part not actually transferred onto transfer paper for the discrimination is avoided and the picture is accurately discriminated.

Title: Crystal growth device and method for growing crystal using the same device
Inventor: FUJIWARA TOSHIYUKI
IPC: H01L21/208
Filed: 1991-02-20
Abstract: PURPOSE:To suppress breakage of a crucible when melting of a raw material for crystal is carried out in a melt layer method. CONSTITUTION:A second heater 32 for heating a crucible 11 is arranged below a heater 22 and all of a raw material S for a crystal packed in the crucible 11 is melted by using these heater 22 and 32. The melt is solidified from the bottom of crucible toward the upper side to form a solid layer consisting of a polycrystal and then crystal growth is started from a melt part of the crucible 11. Since it can be suppressed that melt allowed to flow from the upper part of the crucible 11 solidifies in the lower part of the crucible 11 and thermal shock can also be relaxed by a high temperature in the lower side of crucible 11, breakage of crucible 11 in melting of the raw material S for crystallization can be suppressed. When the crystal is pulled, up, segregation of doping impurity can be prevented, because the heater 32 becomes a body for shielding heat.

Title: Tracking servo device
Inventor: OOTA OSAMU
IPC: G11B7/09
Filed: 1984-02-14
Abstract: PURPOSE:To obtain a tracking servo device which is not effected by the tilt, warp, etc. of a disk by using a signal generating means which performs comparisons among outputs of photodetecting elements and delivers and produces a tracking servo signal and also eliminating the offset voltage before a tracking servo action is started. CONSTITUTION:If VA<A<VB is satisifed with the output voltage A of the 2nd differential amplifier 17, the reflected light given from a disk 10 is deviated toward the 2nd photodetecting element 13 owing to a tilt of the disk 10. Thus a control part 36 performs switching control among the 1st-6th switches SW1- SW6, and the 4th switch SW4 is turned on. Then the output amplification factor of the element 13 is controlled and set smaller than the output amplification factor of the 1st photodetecting element 12. The outputs of both elements 12 and 13 are compared with each other by the 1st differential amplifier 16 to obtain the subsequent tracking servo signals. Thus the offset voltage produced by the tilt of the disk 10 is eliminated. In such a way, the tilt of the disk 10 is decided by the level of the voltage A of the amplifier A. Based on the result of this decision, a difference of amplification factor is produced between the output of both elements 12 and 13. Then the offset voltage is eliminated to perform the subsequent tracking servo operations.

Title: Internal pump
Inventor: SHIINA KOJI
IPC: G21C15/243
Filed: 1995-02-15
Abstract: PURPOSE: To increase a radiation heat transfer amount across the external surface of a pump casing and the internal surface of a RPV(reactor pressure vessel), flatten a thermal distribution in the vicinity of a nozzle and reduce thermal stress by applying a roughened surface structure to at least one of the external surface of the easing and the internal surface of the vessel. CONSTITUTION: High temperature reactor water A is delivered along a lower end plate 1a in a reactor pressure vessel on the rotation of a pump impeller 9, and fed to a reactor body. In this case, the delivered reactor water A flows into a core within the reactor body and generates steams, due to nuclear reaction. Also, hot water and steams are subjected to a two-phase separation process for the removal of humidity and, then, the steams flow to a steam turbine. On the other hand, the hot water A after the two-phase separation process flows down in the pressure vessel and along a down-comer in a shroud 2, and is again circulated on the operation of an internal pump.  Also, seal purged water D is forced to flow in a restricted flow passage between a casing 12 and a pump shaft 11 in an upward direction along the shaft 11, thereby preventing the inflow of a contamination contained in sealing and hot water.
