Title: Method for generating satellite vision map
Inventor: TOMINAGA HIDEYOSHI
IPC: G06T11/60
Filed: 1991-08-19
Abstract: PURPOSE:To easily plural optional vision maps by using an aerial photograph and a map by calculating the vision area of a satellite from height data on buildings and contour figure data on building bottom surfaces and optional inputted satellite position and height data. CONSTITUTION:For the preparation of a satellite vision map 12, a shadow generated by a building model when a light source position is placed at the apparent position of the satellite is calculated geometrically according to the building model and satellite position data 5 and the shadow is displayed on a road map. This shadow approximates to the nonarrival area of the radio wave from the satellite. A map wherein the nonarrival area of the radio wave from the satellite, building bottom surfaces, and roads are displayed in the same image is the satellite vision map 12 and it can be decided whether the satellite can be viewed or not on all the roads in the map. Consequently, a satellite vision map 12 can be prepared even for a different kind of satellite by using an existent building data base 6 by inputting a position, and further the data in the building data base 13 can be updated even when existent data are used.

Title: Optical head and light information-processing device
Inventor: NAGARA TORU
IPC: H01L31/108
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To fully secure sensitivity and receive return light with a sufficient S/N ratio for stable access even if a return light wavelength is short by setting a photodetector to a Schottky diode type. SOLUTION: By setting a photodetector 12 of return light to a Schottky diode type, metal is used instead of the P-type semiconductor of a silicon PN junction type photodetector for creation, thus making thinner than the P-type semiconductor and increasing the quantity of arrival light to a depletion layer by that amount. Also, non-output components can be reduced by direct coupling as in light being absorbed by the P-type semiconductor part by the silicon PN junction type photodetector or the like. In the photodetector 12, sensitivity can be fully secured even if a laser beam L1 has a short wavelength, thus securing a sufficient S/N ratio by a reproduction signal RF or the like of the output of a matrix operation circuit (MA) 14 by that amount in an optical disk device 1.  Therefore, the wavelength of the laser beam L1 is reduced and recording density is improved sufficiently for stable access.

IPC: H04N5/44
Filed: 1992-07-10
Abstract: PURPOSE:To improve the apparent S/N and to prevent disturbance in a picture by adjusting stepwise a high frequency characteristic of a video amplifier circuit as a vehicle speed rises and selecting softer picture quality attended with the vehicle speed. CONSTITUTION:When a video reception circuit 2 is operated to receive a desired radio wave, an audio signal of a broadcast wave is fed to a speaker 4 and a video image is received by a monitor 6. Simultaneously a frequency counter of a control section 9 is reset and speed information of a vehicle supplied to an input terminal 7 is read and counted. The control section 9 discriminates the current vehicle speed based on the result of count of the frequency counter. An output pulse train is compared with data A stored in the control section 9 and the result is discriminated. Thus, a control signal is outputted to an output port A and a picture quality adjustment circuit 10 generates a signal controlled from the output port A. Thus, the frequency characteristic of a video amplifier circuit 5 is corrected so as to attenuate a high frequency by one stage and the apparent S/N is improved.

Title: Preparation of flame-retardant epoxy resin composition
Inventor: KOIKE TSUNEO
IPC: C08L63/00
Filed: 1981-12-24
Abstract: PURPOSE:To safely and easily prepare a flame-retardant epoxy resin compsn., by blending a polyepoxy compd. and a flame retarder obtd. by kneading red phosphorus powder and a polyepoxy compd. which is liquid at ordinary temperature. CONSTITUTION:65-250pts.wt. polyepoxy compd. which is liquid at ordinary temp., is kneaded with 100pts.wt. red phosphorus powder having a particle size of 200mu or below to obtain a flame retarder which is liquid or paste at ordinary temp. The flame retarder is blended with a polyepoxy compd. Pref. examples of said polyepoxy compds. are those having an MW of 200-600 and an epoxy equivalent of 100-300. When the amount of red phosphorus to be blended is less than 40pts.wt. per 100pts.wt. polyepoxy compd., no satisfactory effect as a flame retarder can be obtd., while when the amount exceeds 150pts.wt., the viscosity of the resulting flame retarder compsn. becomes too high and hence it becomes difficult to handle the compsn. Further, the amount of harmful phosphine formed is increased, because the red phosphorus content of the compsn. is high.
