Title: Multifocal molded lens and its manufacture
Inventor: KOGURE KAZUO
IPC: G02B3/10
Filed: 1984-08-17
Abstract: PURPOSE:To improve optical performance by putting a heat-softened glass material in a metallic mold and molding a lens in one body by pressing. CONSTITUTION:The multifocal lens 6 is so formed that a lens 62 which has less curvature than a lens 61 is molded in the center part of the spherical surface of the lens 61 in one body by using the glass material. The upper mold 10 of a metallic mold for press molding which is used to manufacture the multifocal lens is formed in the shape of the bottom surface part of the lens 6 and the lower mold 7 consists of two bodies, i.e. external mold 8 and internal mold 9 as female molds corresponding to the spherical part of the lens 61 and the spherical part of the lens 62. Then, pellets of the glass material are heated and softened in a furnace and put in this metallic mold, thereby finishing the multifocal molded lens 6 by press molding. Consequently, the eccentricity of the lens optical axis is reduced greatly and neither polishing nor cementing is necessary, so the cost is reduced.

IPC: H01S5/042
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a high-speed, which electric current and high-accuracy laser writing device by connecting inductors between a laser writing device and a constant current device and between a dump load and the constant current device, when the laser writing device is connected to the constant current device by a switching means and when the dump load is connected to the constant current device by the switching means. SOLUTION: An electric current from a constant current power supply 32' is made to flow back and forth between a writing laser 34' and a dump laser 36' by activating switches 42', 44' concurrently in a mutually reversed status. In addition, an inductor 46 is built into a circuit between the load and the constant current power supply 32'. In this case, the inductor 46 generates an electromotive force against that of a load inductance, so that the inductor maintains a constant current as it is. If the switch 44' is opened and the switch 42' is closed, the electric current from the dump laser 36' is run back and forth between the dump laser 36' and the writing laser 34', and the electromotive force is generated by a line inductance 38' but is offset by the counter- electromotive force of the inductor 46.

Title: Pushing force control device for medical electrode
Inventor: MIKI AKITOSHI
IPC: A61N1/00
Filed: 1988-07-09
Abstract: PURPOSE:To control the contact pressure of an electrode against the affected part to an optimum condition by providing a slide means for extending and retracting an electrode attaching body in accordance with a contact reaction force, overcoming the urging force of a spring, and a stop control means detecting extraction or retraction of the electrode attaching body, for stopping the operation of an extending and retracting means. CONSTITUTION:When an expansion arm 51 is extended, a slide means 6, an electrode attaching body 1 and a medical electrode 3 are moved in one unit toward the affected part. When the medical electrode 3 makes contact with the affected part, a contact reaction force acts upon the medical electrode 3 so that the electrode attaching body 1 is retracted overcoming the urging force of a spring 66. At this time, a slider 64 fixed to the electrode attaching body 1 is also retracted together on a rail 63. The space between the electrode attaching body 1 and a rising wall 62 becomes narrower so that an end part of a light shield plate 72 attached to the electrode attaching body 1 enters between light emitting and receiving parts of a photomicro sensor 71, that is, a groove 71a so as to shield the light. Accordingly, the photomicro sensor 71 delivers a stopping signal to an extending and retracting means 5 so as to stop the extending motion of the expansion arm 51 at once. Thereby, the medical electrode 3 may be positioned relative to the affected part in a most appropriate contact condition.

Abstract: PROBLEM TO BE SOLVED: To improve the formability and weldability properties of a steel sheet product by forming an oxide coating film on the surface of a protective layer which is formed on the steel sheet product and contains zinc.  
     SOLUTION: A steel sheet product is immersed into a bath containing zinc and the protective layer containing zinc is formed on at least one surface thereof by electric plating or by hot dip coating. For example, a band-shaped steel sheet 1A is immersed into a plating bath 3 within a last cell 2 for plating on an electrogalvanizing process line A and the protective layer is formed on both surfaces of the band-shaped steel sheet 1A by electrochemical plating. The band-shaped steel sheet 1A is taken out of the plating bath 3, is guided to an alklaine treating station 5 and a buffered alkaline soln. 6 containing an oxidant of about 7 to 11 pH is ejected to the protective layer for 1 to 17 seconds without applying voltage.

Title: Molding method for integral-skin foam
Inventor: MABUCHI AKIRA
IPC: C08J9/30
Filed: 1993-06-19
Abstract: PURPOSE:To contribute to improvement in the global environment, form a compact skin layer and obtain the external appearance and touch equal to or more favorable than those in the case of fluorocarbon gas expanding by reducing pressure in a cavity of a mold to a predetermined level and injecting a specified polyurethane material into the cavity to expand it. CONSTITUTION:In a molding method of a semirigid integral-skin foam having a low-expanded self-skin layer 44 and a high-expanded core part 45, pressure in a cavity 4 of a mold 1 is reduced to 50 or more to 700Torr, and a polyurethane material M comprising a polyol component and an isocyanate component as main components, substaintially adding no foaming agent thereto and being prepared by introducing air foam thereinto by air loading is injected into the cavity 4 and expanded. By this method, the heat generated by the reaction between the polyol component and the isocyanate component escapes to the mold, and a temperature at the surface part of the polyurethane material M in contact with the surface of the cavity is hard to rise higher than a temperature of the cavity. Therefore, the increase of a viscosity is surpressed, defoaming becomes easier and the surface part of said material turns into the low-expanded self-skin layer 44.

Title: Measuring method for inspection of accuracy of machine tool and device for executing said method
Inventor: UORUFUGANGU KUNATSUPU
IPC: G01B7/00
Filed: 1983-09-20
Abstract: A system for determining the precision of a numerically controlled machine tool involves setting the machine tool control to define a circular path. A circular standard is then aligned with the machine tool to sense the desired circular path. A continuous or pointwise sensing, as a function of whether a path-controlled or a point-by-point-controlled machine is being measured, of the aligned standard is performed. A faulty machine tool does not accurately cover the defined circular path. Variations from the desired circle can be plotted and used for evaluation.

Abstract: PURPOSE:To reuse a carrier and to measure an antigen accurately, by adsorbing the proteinic high molecular antigen to the insoluble carrier combined an antibody of this antigen tagged by enzyme through S-S bond under the existence of hydrophobic protein and salts. CONSTITUTION:Tagged antibody by enzyme of a proteinic high molecular antigen (alpha-fetoprotein, all sorts of peptid hormones) to be measured in blood serum or urine is combined by S-S bond on the surface of an insoluble carrier such as nylon. After the sample containing said antigen is reacted to said fixing tagged enzyme antibody, the S-S bond is cut by a reducing agent such as thiodislateol and combined body of enzyme-antibody-antigen is eluted and then, the quantity of the antigen in the sample is determined by measuring the enzyme activity in an eluate. On the one hand, the insoluble carrier can be reused by combining the tagged antibody again. Hydrophobic protein such as gelatine and salt of Na, are let coexist in the system to react the antigen-antibody and the accuracy of measurement is improved by restraining the action of interfering substance containing in sample living body fluids.
