Title: Laser scanning optical system
Inventor: IMAGAWA SUSUMU
IPC: G02B27/00
Filed: 1987-02-03
Abstract: PURPOSE:To reduce side lobe generated by diffraction and to improve the quality of an image by arranging a density filter maximizing transmissivity on an optical axis and continuously dropping the transmissivity in accordance with a distance separated from the optical axis in an optical path before a polarizing means. CONSTITUTION:The density filter 18 is arranged between a collimeter lens 4 and a rotary polygon mirror 12. The filter 18 has transmissivity characteristics minimizing the transmissivity on a center part corresponding to the optical axis and increasing the value in accordance with the distance from the center part to a peripheral part. When parallel light is shaped by the density filter, i.e. a kind of an aperture, having said transmissivity characteristics, the influence of diffraction can be reduced differently from shading due to an edge part of an ordinary aperture. Consequently, side robe in the distribution of beam intensity on recording paper can be reduced and the quality of picture can be improved.

Abstract: PURPOSE:To detect the position where a partial discharge is generated by detecting the discharge pulse with a coupling capacitor, amplifying in the manner of tuning with a resonance frequency given from sweeping the pulse, and obtaining the resonance frequency in which an amplification sensitivity is made to be minimum. CONSTITUTION:The discharge pulses which are detected by the coupling capacitor (Ck) connected to a cable (Ca) to be tested are sent out to a resonance amplifier 11.

In the amplifier 11, the discharge pulses detected by the capacitor (Ck) with plural different resonance frequencies are tuned respectively and amplified with each resonance frequency to send out to a sorting circuit 5. A distributing condition of each measured value which are amplified with the swept resonance frequency is detected in the circuit 5 wherein the resonance frequency (f) at the time when the amplification sensitivity is made to be minimum is sorted out. A distance (X) from an electricity applying point (A) of the cable (Ca) to a faulty point (partial discharge generating position) 40 can be obtained by X=D-L=D-V/4f (D: overall length of cable Ca, L: distance from faulty point 40 to distant end B, V: propagating velocity of pulse).

Title: Surface alloying method by laser light
Inventor: INAGAKI MASATOSHI
IPC: B23K26/352
Filed: 1979-03-05
Abstract: PURPOSE:To enhance laser light absorptivity and readily make possible surface alloying by coating the element-coated layer by the metal of the reflectance equal to or lower than that of the base metal main component at the time of melt-alloying the additive element of a laser light reflectance higher than that of the base metal on the base metal surface. CONSTITUTION:Base metal 3 such as Ni is coated with an additive element layer 2 such as Al, on which is applied a coating layer 3 of the metal of the reflectance equivalent to or lower than that of the base mtal main component or the melting point equivalent to or higher than that of said component. When laser light 1 is radiated to this surface, first the coated layer 3a melts and the element 2 melts as well owing to heat conduction, whereby the melt alloy layer 4a is formed. When the radiation is continued further, the element layer 2 completely melts. At this time, the additive element has alloyed with the coating layer 3a so that the selective evaporation away of the additive element may be prevented. When the melting point of the alloy layer 4a is higher than that of the additive element 2, this effect may be expected further. When the radiation is further continued, it melts with the very surface of the base metal 3, whereby the alloy layer 4a of good adhesiveness may be obtained.

Title: Polymer particle and production thereof
Inventor: TAGAMI EIJIROU
IPC: G01N33/545
Filed: 1981-02-24
Abstract: PURPOSE: To obtain polymer particles having rough surfaces and an increaced surface area, by polymerizing a monomer mixture containing an aromatic vinyl compound and a cyanoethylene compound at a specified monomer/water ratio or at a specified combination.  
     CONSTITUTION: A monomer mixture consisting of 50W90wt% aromatic vinyl compound, 10W40wt% cyanoethylene compound, 0W15wt% α,β-ethylenically unsaturated carboxylic acid and 0W20wt% other vinyl compounds copolymerizable therewith is polymerized by batchwise or continuous charge emulsion polymerization. In case of the batchwise monomer charge, the particle shape varies with a monomer to water ratio, and it is spherical at high monomer to water ratio. Therefore, the polymerization is carried out at a monomer to water ratio of 0.01W0.1. In case of the continuous charge, at conversions <80%, particles with rough surfaces are hardly obtained, and so the polymerization is carried out so that the conversion is always maintained at 80% or higher.
