Abstract: PROBLEM TO BE SOLVED: To provide a method for molding a glass molded product simply by directly carrying out the press molding and fabrication of a glass product such as an optical element having a highly accurate shape and a high surface accuracy from a molten glass gob in a molten and softened state without using after processing such as grinding or polishing at all.

SOLUTION: This single layer type vertical magnetic recording medium is formed with the vertical magnetization film 13 on the nonmagnetic substrate 11 via an underlying layer 12 for the purpose of vertical orientation property and crystal grain diameter control of the magnetic film. The vertical magnetization film 13 is made of a Co alloy to form a polycrystalline film, and a crystal grain diameter is <=20 nm, and then a nonmagnetic element is preferentially segregated in a crystal grain boundary. Then, the soft magnetic film or the intra-plane anisotropy magnetic film 14 is formed on the vertical magnetization film 13 which is larger than this magnetic film 14 in thickness, and hence magnetic flux generated by magnetic fluctuation on the surface of the vertical magnetization film 13 is absorbed by the magnetic film so as to reduce noise.  Then, in order to realize recording density of >=5 Gb/in<2> , the total film thickness of the vertical magnetization film 13 and the soft magnetic film 14 is 7 to 100 nm.

Next, an arithmetic unit 11 operates the value of ion exchange capacity from the value of a conductive degree of the dielectric fluid before the ion exchange and the value of the conductive degree of the dielectric fluid immediately after the ion exchange, and remaining operating time till reaching the service life of the ion exchange resin is found out of both values of ion exchange capacity and ion exchange flow on the basis of a life characteristic inherent in the ion exchange resin. And, At a display unit 12, the ion exchange capacity found by the arithmetic unit 11 and the residual operating time of up to the service life are displayed, informing an operator of this fact. Thus, the service life of the ion exchange resin is clarified whereby operation is performable so economically and efficiently.

Title: Fork-type optical chopper
Inventor: SHIODA JIYUNICHI
IPC: G01J1/04
Filed: 1978-11-14
Abstract: PURPOSE:To obtain a fork-type optical chopper, whose excitation power and oscillation leakage and variation of oscillation frequency by aging are small, by attaching a shutter inside a beam section of a fork oscillator having 2 beam sections, so that incoming light can be screened. CONSTITUTION:Shutters are attached to inside of respective fork beam sections 22 in such a manner that when the beam sections 22 are not vibrating there is a gap allowing a beam-like light signal to pass through and that the beam sections are crossing each other without contacting each other in the condition that they are making maximum displacement inwardly. The light signal is concentrated by No.1 lens so that the focus comes to the center of the gap of the shutters, and then, it is converted into a horizontal light by No.2 lens. Since, in this mechanism, light is screened when the beam sections 22 are displaced inwardly by eual amount, each beam section is required to be displaced by only 1/2 of displacement required for intermitting the light signal, and therefore, it is possible to reduce exciting power, oscillation leakage and variation of oscillation frequency by aging.
