Title: Thermal infrared sensor
Inventor: TAKADA HIDEJI
IPC: G01J1/02
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain a thermal infrared sensor whose sensitivity and reliability are enhanced and whose production costs are reduced by a method wherein films whose infrared reflectance is high and whose thermal conductivity is good are formed, by photolithography, in the lower layer of an infrared-ray receiving part and in a position which covers a cold junction at a sensor pattern. SOLUTION: Films 51, 52 whose infrared reflectance is high and whose thermal conductivity is good are formed in the lower layer of an infrared-ray receiving part 6 composed of a resin material containing a trace amount of carbon and in a position which covers a cold junction Pc at a sensor pattern 3. The films 51, 52 are formed by a patterning operation by photolithography. Since infrared rays which are transmitted through the infrared-ray receiving part 6 are reflected immediately by the film 51, the absorptance of the infrared rays in the infrared-ray receiving part 6 is enhanced. On the other hand, since the cold junction Pc is covered with the film 52, infrared rays which are incident on the cold junction Pc are reflected by the film 52, the temperature rise of the cold junction Pc is prevented effectively, and the sensitivity of a thermal infrared sensor is enhanced.  In addition, since the films 51, 52 are formed by photolithography, a man-hour is reduced, and a yield is enhanced.

Abstract: PROBLEM TO BE SOLVED: To maintain all operations of an IGBT within a safe working area without requiring any limiting device nor monitoring device on a load side by causing a control current formed in accordance with the compared results of the actual voltage value of a gate electrode with a desired value to act on the gate electrode.

Title: Processing method for monochromatizing color display signals
Inventor: YAMANE ETSUO
IPC: G09G5/10
Filed: 1988-03-15
Abstract: PURPOSE:To recognize an image even when the color display signal is displayed on monochrome display equipment by edging the borders of areas which are adjacent different color areas of the color display signal and painted in the same color by using the complementary color. CONSTITUTION:When the kinds of respective picture elements on coordinates X and Y are represented ad D(X, Y), the area R1 shown between the broken line and solid line from, for example, D(7, 7) to D(36, 7) is an area of red R with the color display signal, but displayed in white W with the monochrome signal. The area, however, adjoins to an area of green G along a border line L1 as shown by a solid line, so the area is converted to black BK and used as part of an edged area. Thus, different color display areas in an image are all displayed in the same color, but the borders of those areas are all edged in the complementary color, so the shapes of those areas are recognized clearly with edging lines.

Title: Data reading method for optical card
Inventor: NISHIMURA JUNICHI
IPC: B42D15/10
Filed: 1989-03-14
Abstract: PURPOSE:To attain the correct read of a data by reading a data from both forward and reverse directions and connecting data normally at the front and rear of the flaw. CONSTITUTION:When forward reading is applied, the read is started from a sync mark 1, the data is read normally till a flaw data and mis-reading is caused from the flaw data till the end of read. In the case of reverse reading, normal data reading is applied from a sync mark 2 till the flaw data and mis- reading is applied from the flaw part till the end. When both read data are connected, that is, the normal readings from the forward and reverse directions are linked, the result is that mis-reading is very slight less than the limit of the error correction capability and within the error correction capability. Thus, correct data area read.

Then an error signal 6 is transmitted when the voltage value of the signal 3 is smaller than that of the signal 4. Furthermore a deciding circuit 14 detects the holding time of the signal 6 and transmits a crash signal 7 when the signal 6 is held for a prescribed time or longer to inform the occurrence of the head crash. In such a way, the head crash is quickly detected.

Abstract: PURPOSE: To remove the mixed existence of an analog circuit and a digital circuit on the same silicon substrate and to minimize the drift caused by the characteristic variation of parts due to the temperature by completely constituting a digital pulse width modulator having a proportional dither of a digital circuit. CONSTITUTION: Control logic 48 is started by a trigger pulse based on a signal f4 and an 8-bit command word is supplied to a latch 42. It is also available to use 16-bit, 24-bit or 32-bit word. The command word is preloaded to a down counter 44 based on a suitable signal from the logic 48 and a clock gate 46 activates the counter 44 to generate a base signal HB having pulse width based on the word value. When the time-out of the counter 44 occurs, a dither pulse generator 32 is triggered, a flip flop is reset and the input of the gate 46 is turned to '0' to stop the counter 44.

Title: Color cathode-ray tube
Inventor: MISONO MASAYOSHI
IPC: H01J29/50
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To improve a focus characteristic in the whole area of a fluorescent screen and also in the whole electric current area of an electron beam, and obtain excellent resolution by forming different electron lenses of an electron beam positioned in the center of electron beams and an electron beam positioned on the side. SOLUTION: A main lens L3 to an electron beam positioned in the center is a lens whose spherical aberration is large and aperture is small. To the contrary, it follows that a main lens L3 to an electron beam positioned on the side is a lens whose aperture is large since spherical aberration is small. In this way, since the focusing actions of a prefocus lens L1 and the main lenses L3 acting on respective ones of the electron beam in the center and the electron beam on the side are made different from each other, a diameter (d) of an electron beam spot formed on a fluorescent screen 24 can be equalized, and resolution in the whole image screen area can be improved.

Also, by eliminating the data for the new registration from the data base 22 and using the data before the registration, the registration is canceled. Further, by using the data base 22 of a copy destination for registration and the one of a copy origin for retrieval, the registration and the retrieval to the same data base are simultaneously performed.
