Title: Laser scanning type microscope equipped with aotf
IPC: G02B21/00
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To guarantee the stability of laser performance to necessary ultraviolet-ray wavelength and a visible spectrum range by providing a temperature sensor at the periphery of an acoustooptical temperatures sensor(AOTF) or nearby it or while the temperature sensor is coupled with the AOTF. SOLUTION: Temperature detectors which detect ambient temperatures of respective AOTFs are fitted directly to the AOTFs and the temperatures are transmitted to a central control unit 34 which has an arithmetic function. The arithmetic function adjusts and optimizes the AOTF-to-frequency relation of temperature dependency in a frequency range by a previously stored correction curve and a driving circuit. Namely, a frequency shift caused by variation in temperature is compensated by increasing or decreasing the frequency. This compensation can be performed on the basis of the intensity value of a laser beam picked off by a diode 19. Namely, an AOTF driver controls the frequency by varying the frequency up to the highest frequency according to the intensity signal picked off by the diode 19.

Filed: 1992-06-04
Abstract: PURPOSE:To abolish the 100% appearance inspection which is executed in a sorting process by a method wherein the accuracy of the inspection of a lead bend at a package for a semiconductor device is enhanced. CONSTITUTION:A groove which is provided with an inner wall 4 and an outer wall 5 is formed in a lead-bend detection block 7. A lead insertion hole 6 is made in the bottom of the groove. Thereby, even regarding a product in which a lead 3 is bent outward and jumps largely or regarding a product in which the lead 3 is bent inward and bent so largely as to come into contact with the bottom face of a package 2, the displacement of a displacement block 12 can be detected by means of a displacement detection sensor 13 because the lead 3 comes into frictional contact with the inner wall 4 and the outer wall 5 and presses down the lead-bend detection block 7. In addition, since it is not required to insert an inward bent lead into the lead insertion hole 6 deep, the accuracy of the detection angle of the inward bent lead is not affected.

Filed: 1985-07-02
Abstract: PURPOSE:To enable to control to a high speed zone by adding amplifying means for amplifying a difference signal between an output of a steady-state deviation compensator, a rotating speed signal and an output of observer means when a circuit is saturated. CONSTITUTION:A steady-state deviation compensator 6 integrates and amplifies a deviation between the rotating speed of a motor 2 from detecting means 5 and a target value. Comparing means 10 compares the output of the compensator 6 with outputs of output amplifying means 9 of rotating speed amplifying means 7 and observer means 8. Driving means 12 drives a motor 2 by the output of amplifying means 11 for amplifying the difference signal of the means 10. Since the signal from the means 10 is amplified by adding the means 11 when a rotating speed is high and the circuit is saturated, it is controlled even at high speed without saturation of the circuit.

Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To improve an image reproducibility by specifying a reflectivity of an illuminated light having the same wavelength as that of a laser beam of a base of a direct lithography type lithographic printing plate master. SOLUTION: In the case of transmitting an illuminated laser beam through a thermosensitive layer, an adverse influence of a reproduction fault or the like of fine halftone dots according to removal or drop of the layer by an excess supply energy from below the layer and a halation from below is affected to the layer. Thus, a reflectivity of a base is set to less than 50%, or particularly it is best to set it to less than 10%. If the reflectivity of the base is higher than 50%, the layer is affected from below by a laser beam reflected on the base through the layer. As a method for providing a scattering means for realizing the less than 50% of the reflectivity, there is a method for roughing treating such as anodizing, alkali treating, graining treatment or the like of the base.  Meanwhile, as a method for providing a means for transmitting and absorbing a laser beam, there is a method for forming the base itself as a material for transmitting or absorbing the laser beam.
