Title: Image data forming method
Inventor: YOSHIDA ATSUSHI
IPC: H04N1/40
Filed: 1992-12-08
Abstract: PURPOSE:To obtain an image data forming method by which image data with precision can be obtained even if a white level correction is performed. CONSTITUTION:After a dark time correction is performed for the photoelectric conversion signal from an array sensor 11 in a subtracter 12, prescribed conversions (logarithmic conversion and normalization) are performed in a lookup table 15. A white level correction is performed for the converted data in a subtracter 19. If the image signal of a picture element 'i' is Ri and a sensitivity factor is ci, the output Ds of the subtracter 19 becomes Ds=(logRi)/alphaI:-alphaI<=log (Rici)<=0=-1 - (logci)/alphaI:log (Rici)<=-alphaI. The value of Ds is increased by 'alphaI/alphaE' (alphaI>alphaE) and becomes image data in a lookup table 20.

IPC: H01C17/242
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To avoid the reaching of the thermal effect in laser beam trimming on a part other than a trimming groove by blowing the gaseous cooling medium to the vicinity of the part among a resistor film and a protecting film, to which laser beam is projected, and projecting the laser beam under this state. SOLUTION: When a trimming groove 2 is cut and provided in a spiral shape by a laser beam trimming method for a cylindrical resistor 1, the cooling medium such as air, which is compressed by a compressor 8 and cooled to the temperature lower than atmospheric temperature by a cooler 9, is blown to the vicinity of a part, to which the laser beam is projected, at the outer surface of the cylindrical resistor 1 through a nozzle 10. Thus, among a resistor film and a protecting film, the vicinity of a part, to which the laser beam is projected, can be sequentially cooled, and the range affected by the thermal effect in the laser beam trimming can be made small.

Filed: 1988-12-27
Abstract: PURPOSE:To freely set the horizontal width and the display start address of a display memory by allocating a divided address space of an even number to a dual port memory module DPM0 and a divided address space of an odd number to a DPM1 respectively. CONSTITUTION:A display period starts and a clock S17 and an output enable S18 are given to a module 0 that performed the first read transfer. Then the display data S16 is outputted from a serial port. A clock S19 is not given to a module 1 and therefore an address counter is set at 0. Then an output enable S20 is negated and the output of the module 1 has a high impedance. When the address bits A1 - A8 of a display address counter 110 are all equal to 0, the clock and the output enable of the module 0 are switched to the module 1. Therefore the second read transfer is performed for the next display period when the next display data is outputted from the module 1 and a blanking period starts after the first display period is through.

Title: Object detector
Inventor: NAGURA NARIMASU
IPC: G01V1/00
Filed: 1987-12-28
Abstract: PURPOSE:To reduce a sensing range and contrive the improvement in the detecting precision of a minute object by imparting a detector with a directivity without dispersing supersonic waves through a pair of wave guides to propagate. CONSTITUTION:The supersonic waves emitted from a transmitter 3 is propagat ed through a pair of wave guides 1, 2 and received by a receiver 4. Electric signals generated from the receiver 4 are changed depending upon the presence or absence of an object S in the separated space between wave guide 1, 2, thereby detection of the object S can be realized. Since the detector is allowed to have directly to propagate without dispersing the supersonic waves through the wave guides 1, 2, a sensing range of the object S can be reduced in the separating space and the detecting precision of a minute object can be improved. Further, a propagating path of the supersonic waves can be set freely and an installation space of the detector is not restricted by changing a piping configuration such as bending and altering in its length.
