Title: Floppy disk
Inventor: USHIGOME HISASHI
IPC: C09D7/12
Filed: 1986-03-10
Abstract: PURPOSE:To predict the result of a practical durability test by limiting the elastic loss value in the viscoelasticity measurement of a magnetic layer to a prescribed range between specific temp. ranges. CONSTITUTION:The result of the durability test of the magnetic layer, with which the tan delta value (temp. change of the viscoelasticity characteristic) in the measurement range of (110Hz, 2deg/min) at a -5-+50 deg.C range is in a 0.07-0.12 range, clears 10 million passes when the result of the durability test and the tan delta value of only the magnetic layer are compared. The result of the durability test is thus predicted from the tan delta value by the viscoelasticity measurement of the magnetic layer in the practical durability test of a floppy disk which is difficult and with which the result is hardly predictable. Conversely, the large directivity of development in the design of the medium for the floppy disk is given in terms of an assembly stage.

Title: Vapor cooling rectifier
Inventor: SHINOHARA TAKAHIRO
IPC: F25D9/00
Filed: 1978-04-28
Abstract: PURPOSE: To keep each pressure container under the same conditions in terms of liquid temperature, pressure and capacity, and also to prevent an accidential wave by coupling together the  vapor-phase and liquid-phase parts of each pressure container via pipes and by providing each  pipe with an electromagnetic valve which operates by a differential pressure relay.   
     CONSTITUTION: During the normal operation, electromagnetic valve 14 is open even if insufficient thermal radiation of center condensing unit 7 causes the Flon-solution temperautre of pressure container 3 to become higher than the liquid temperature of any other container, they remain  equalized in pressure and in liquid temperature since they are coupled together via pipes 10 to 14.  With vapor-phase parts coupled via pipes 10 and 11, some of a refrigerant vapored in center container 3 is condensed by condensing units 6 and 8 in containers 2 and 4 at both the sides, so that  the surface of the liquid in container 3 will fall. With only liquid-phase parts coupled together via  pipes 12 and 13, the liquid in container 3 is forced to move into both containers 2 and 4, so that  the liquid level will also fall. In this way, the liquid level is kept constant and the rectification arm  will never be exposed to the vapor- phase part. If a difference in pressure with a normal container  is made by accident, relay 15 operates to close electromagnetic valve 14, thereby releasing the  pressure of the fault container.

Title: Electrophoresis measuring apparatus for flat particle
Inventor: OOKUBO KUNIHIKO
IPC: G01N21/64
Filed: 1980-04-18
Abstract: PURPOSE:To improve the accuracy in measurement by a method wherein after the particle image signals in picture signals have been converted into one pulse signal independently of the intensity and width thereof, the correlation between the pulse signals obtained at an interval of time is obtained. CONSTITUTION:The images of the suspended particles, which are obtained by irradiating an electrophoretic tube 1 by a laser beam source 4, are formed on a diode array element P. The picture signals obtained by scanning the array element P are smoothed by means of a filter and differentiated in a differentiation circuit D. The differentiated signals enter a level selector L, which outputs signals of level more than a given value. Thereby, background signals and out-of-focus particle image signals, which have gentle rising and falling, are removed. The differentiated signals of thus obtained in-focus particle image signals are used to trigger a one-shot circuit m to obtain signals of given height and width. After the signals obtained by scanning the array element P at a given interval of time have been stored in memories M1 and M2, the correlation between both the signals is obtained.

Title: Nd-doped fiber laser system
Inventor: KIMURA YASURO
IPC: G02B6/00
Filed: 1987-03-09
Abstract: PURPOSE:To obtain a fiber laser system whose threshold value is low and whose output is high by using a quartz-related optical fiber whose core is doped with P together with Nd. CONSTITUTION:An optical fiber 4 is a quartz-related optical fiber which is doped with, e.g., Ge so that a refractive index is distributed; its core is doped with at least Nd and P. In addition, a reflector is installed at the output side. That is to say, because P together with Nd is doped, the extinction by density due to the increase in the Nd can be suppressed, it is possible to increase laser- active ions Nd<3+>. Accordingly, even when the high-concentration Nd is doped, the extinction by density due to the simultaneous doping of the P is not caused. By this setup, it is possible to obtain a high-output fiber laser system.
