Title: Optical recording and reproducing device with semiconductor laser as light source
Inventor: NAKADA AKIFUMI
IPC: G11B7/08
Filed: 1979-02-13
Abstract: PURPOSE: To shorten a light path length to make an optical sytem small-size and improve transfer efficiency of a light, by using two cylindrical lenses to convert the light from a laser light source, which has a plane luminous face, to a parallel light.  
     CONSTITUTION: The sectional form of the light beam on the luminous face of a semiconductor laser is generally plane in relation to its junction face. When only the light at the center of this plane luminous face is condensed, transfer efficiency is lowered to several %, and a required light path length is long. The emission light from semiconductor laser 11 is converted to a parallel light of an approximately round section between concave cylindrical lens 14 and convex cylindrical lens 15 and is condensed to a small beam diameter on disc 19 by condenser lens 18. By this constitution, the light path length of the condensation optical system can be shortened considerably to make the unit small-size, and light transfer efficiency of the light beam can be improved up to 40W50% or more.

IPC: H01F41/02
Filed: 1989-01-27
Abstract: PURPOSE:To perform rust preventive treatment not deteriorating a magnetic characteristic with good productivity by applying paint mainly composed of alkyd resin having viscosity of 100 to 300 centipoises to the whole surface of an iron core formed by winding or lamination. CONSTITUTION:After forming an iron core by winding or laminating an iron- based amorphous magnetic alloy thin tape, annealing is performed. Cold setting type paint mainly composed of alkyd resin such as epoxy conversion alkyd is applied to the whole surface of the iron core as a rust preventive agent. This paint is put under control to have viscosity in the range of 100 to 300 centipoises by adjusting a blending rate of pigment and a solvent for being applied by a method of spraying and brushing followed by drying. Thereby, rust preventive treatment of the iron core can be performed only by application to the surface of the iron core. Further, the paint is prevented from immerging between the layers of the iron core so that lowering of a magnetic characteristic is not generated.

Filed: 1986-01-27
Abstract: PURPOSE:To obtain the good accuracy of quantitative determination similar with both a high-concn. sample and low-concn. sample by lighting up a hollow cathode lamp which emits the bright line spectra of the elements to be quantitatively determined by large current pulses. CONSTITUTION:This analyzer is provided with the hollow cathode lamp HCL, a photomultiplier PM, a preamplifier PA, capacitors C1, C2, differential amplifiers SB1, SB2, logarithmic amplifiers L1, L2. The output signal of the amplifier PA is compared with a reference signal Er by an error amplifier Ea when the output of the amplifier SB2, i.e., the lamp HCL emits the light of a wide bright line width. A high voltage generator HG is controlled by the difference between the two signals and the high voltage thereof is fed back to the detector PM. The absorption signal during the time when the lamp HCL emits the broad bright line spectra is so controlled as to maintain the specified value, by which the same effect as the effect of a two beam spectrophotometer is obtd. The measurement of the concn. with high accuracy is thus made possible.

Abstract: PURPOSE:To uniformly and surely apply oil to the toner image forming surface of a transfer material to be fixed by specifying a ratio of a kinematic viscosity value of oil impregnated to an oil impregnated pad and a kinematic viscosity value of oil impregnated to an oil applying roll. CONSTITUTION:As for a ratio of a kinematic viscosity value upsilon2 of oil 2 impregnated to an oil impregnated pad 113 and a kinematic viscosity value upsilon1 of oil 1 impregnated to an oil applying roll 8, it is desirable that it is set to upsilon2:upsilon1=1:3-1:30. In this state, when the kinematic viscosity value upsilon1 of oil 1 is fixed to 30,000cst, when the kinematic viscosity value upsilon2 of oil 2 exceeds 10,000cst, oozing speed from the oil impregnated pad 113 becomes low, therefore, when an ambient temperature is low and when usage of the device is started, unevenness is generated in an oil applying state. Also, when the kinematic viscosity value upsilon2 of oil 2 becomes <=1,000cst, the oozing speed from the oil impregnated pad 113 becomes high, therefore, when the ambient temperature is high and when the device is being used, oil is applied excessively. In such a way, oil is applied uniformly and surely.
