Patent JP-H08184613-A (JP)
Title: Waveform comparator
Inventor: TAKAI TORU
IPC: G01R13/20
Filed: 1994-12-27
Abstract: PURPOSE: To compare an analog input signal with a reference waveform as to the waveform part stored in a reference waveform memory at each period of continuing an incoming analog input signal. CONSTITUTION: A reference waveform memory 36 stores a reference waveform data corresponding to an analog input signal to be compared. A time base controller 18 starts to read reference waveform data from the memory in response to a trigger signal generated from a trigger circuit 16 when the analog input signal crosses a predetermined level set to the circuit 16. The read data is converted to an analog output signal by a digital-analog converter 38. A difference detector 40 compares the analog output signal with the analog input signal to generate a detection signal when the difference exceeds a predetermined value.

Title: Method and device for measuring extinction ratio
Inventor: FUKUCHI KEISUKE
IPC: G01N21/27
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To accurately measure an extinction ratio of a linear polarizer by detecting the maximum and minimum values out of beat signals detected by a photodetector when an object to be measure is rotated. SOLUTION: A light 1a emitted from a light source 1 is separated with a beam splitter 3 into a light passage 1 and a light passage 2. Then the beams from the passages 1 and 2 are superimposed with each other by a beam synthesizer, and they are converted into electric signal through a photodetector 10 so as to obtain beat signals. The angle of a mirror is adjusted so as to make the beat signal the maximum. In addition, a polarization adjusting unit 13 is adjusted for the passage 2, referring to the beat signal. After adjustment, a linear polarizer 7 to be measured is arranged on the passage 1 and it is rotated, allowing the signal level to change. The beat signal against rotation is sent to a processor 14, and the maximum and minimum values of the beat signal level are recorded, then a ratio of both values is calculated to obtain an extinction ratio of the polarizer 7.

Title: Image processing unit and its method
Inventor: AMAMIYA MASAMI
IPC: G06T1/00
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To avoid improper image frame addition processing from being executed in the high speed image frame addition processing by means of the hardware. SOLUTION: An original image outer shape detection section 300 discriminates whether or not an outer shape of an original image read by an original image read section 100 is a rectangle. When the shape is not a rectangle, since proper image frame addition processing is impossible in an image frame addition processing section 400, a different shape detection signal 310 is given to an exception processing section 700. The exception processing section 700 controls the transmission of an image so that the image to which improper image frame addition processing is applied is not transmitted to a host computer 600.

Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To decrease the fluctuations of optical axis by welding, and to lessen the insertion loss, by irradiating the tapered surface of a thin flange part with a laser to the extent that the fusion by the heat of the laser penetrates down to the rear side. SOLUTION: A cylindrical holder 30 having an end face, which is fixed at one end of an optical fiber 18 in order to couple one end of the optical fiber 18 to optical parts 14, is pressed to the end face of the optical parts 14 at the time of coupling to the optical parts 14 and is smaller than the end face of the optical parts 14 is provided with the flange part 32 having the surface within the same plane as the plane of the end face of the holder. The holder 30 having the flange part of such thickness through which the melting by the heat of the laser penetrates down to the rear side at the time of subjecting the flange part to laser welding from a diagonal direction, is obtd. Then, the weld zone is made thinner by irradiating the tapered surface of the flange part 32 with the laser. Since only the flange part 32 is melted, the force in the axial direction generated by thermal expansion may be relieved upward of the flange part 32 and the lateral shifting of the holder 30 is lessened.

Abstract: PURPOSE:To prevent generation of a non-soldered part by a method wherein the openings of nozzles are arranged in two directions, a direction almost going straight against the moving direction of the material to be soldered and another direction which is the same as the moving direction of the material to be soldered. CONSTITUTION:The molten solder jetted out from a nozzle 10 streams in B- direction which is in the same direction as the moving direction A of a printed wiring board but on the reverse direction against the lower surface of the printed wiring board which moves to A-direction on nozzles 10 and 11. On the other hand, the molten solder jetted out from the nozzle 11 is streams along a vane 13 to the C-direction which crosses at a right angle with the moving direction A of the printed wiring board. As the molten solder streams not only to B-direction which is the same as the moving direction of the printed wiring board, but also to C-direction which crosses at a right angle with the moving direction of the printed wiring board as above-mentioned, the residence of air and gas behind the electronic component mounted on the printed wiring board and in the recessed part between the adjacent electronic components can be prevented. As a result, non-soldered part can be prevented.
