Title: Double refraction measuring instrument
Inventor: MATSUBARA AKIRA
IPC: G11B7/26
Filed: 1990-01-29
Abstract: PURPOSE:To simultaneously measure the direction and the quantity of double refraction even concerning a transparent medium in which the variance of the directions of the double refraction is not uniform by constituting a device so that the double refraction quantity of a double refraction variable means may be changed in accordance with the received light quantity while the transparent medium which is a measured object is rotated with reference to an emitted light and polarized light separation means. CONSTITUTION:Linearly polarized light projected from a laser 11 passes the surface layer 13 of an optical card 12 which is the transparent medium and is reflected by the optical card 12 to pass through the surface layer 13 again. It becomes elliptically polarized light because its deflection characteristic is changed in accordance with the direction and the quantity of the double refraction of the layer 13 and is adjusted by a Babinet-Soleil compensator 23 so that the s-polarized light component may be maximum, then it becomes the linearly s-polarized light at a point where the double refraction direction of the surface layer 13 and the crystal axis of the compensator 23 coincide with each other. At such a time, the direction and the quantity of the double refraction of the surface layer 13 are measured based on the rotational angle of a turntable 22 and the crystal axis direction of the compensator 23 and based on the double refraction adjusting quantity known from the moving scale of a 2nd stepping motor 24 respectively.

Abstract: PURPOSE:To simplify a measuring method by heating a pellet formed by molding an Ni-containing ore and observing the height of the pellet and calculating the relational chart of heating temp. and the height of the pellet to measure the softening and melting temps. of the ore. CONSTITUTION:An ore with Ni content of 1% or more is ground to mold, a pellet. A core pipe 11 is introduced into a furnace 1 and the molded sample pellet 4 is placed on planking made of alumina to be arranged in the pipe 1'. A thermocouple is brought into contact with the pellet and the pellet is gradually heated to high temp. according to a temp. rise pattern to measure the temp. of the sample pellet 4. When the sample pellet 4 becomes high temp., the pellet 4 is gradually softened and shrunk and the height thereof is reduced and, therefore, the height of the pellet is measured through an observation window 2 using a cassette meter as a measuring means. When the relational chart of measuring temp. and the height of the sample pellet 4 is calculated, a suddenly changing point appears in the relational curve of the relational chart and, therefore, the softening.melting temp. of the ore is determined from the point. Since gas is introduced into the core pipe, an introducing port 6 is provided to one end of the pipe 1' and an exhaust port 6' is provided to the other end thereof.

Title: Lens position detector
Inventor: II TOSHIYUKI
IPC: G02B7/09
Filed: 1987-01-29
Abstract: PURPOSE:To perform highly durable and stable position detection without contacting by detecting a light-shade pattern part provided to the outer periphery of a focus ring or zoom ring optically by a photosensor. CONSTITUTION:Infrared rays l emitted by a light emitting element 23 pass through 19a of an optical fiber 19 and are transmitted to a projection lens 15 and projected on the light-shaped pattern part 12a printed on the circumference of the zoom ring 12. The infrared rays (m) are reflected by a white part of the pattern part 12a, projected into a fiber 19 through a lens 15, and transmitted to a light receiving element 27 through 19b of the fiber 19, so that the infrared rays (n) from the element 23 are detected. The opposite surface of the projection lens 16, on the other hand, is a black frosted part on the surface of the ring 12 and infrared rays which are emitted by a light emitting element 24, transmitted by an optical fiber 20, and projected by a lens 16 is hardly reflected, so a light receiving element 28 detects no reflected light. Thus, the prescribed light-shape pattern part is only provided to the circumferential part of the ring 12 to obtain a corresponding signal, and the position of the ring 12 can be detected.

Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a video transmitter which can connect the arbitrary number of images more than the number of channel resources provided for a transmission medium. SOLUTION: In video transmitting state storage means corresponding to respective video input means 1011 -101n , the channel resources as many as video output means 1031 -103n connected to these video input means 1011 -101n are virtually held and when the video output means 1031 -103n switch the connection to the other video input means 1011 -101n , the held channel resources are dispatched to the video input means 1011 -101n of targets to be switched so that the arbitrary number of images can be connected. Thus, since the centralized management of channel resources for the transmission medium is performed by a video connection managing device 109, the channel resources are dynamically allocated, and the video input means 1011 -101n and the video output means 1031 -103n are connected by the allocated channel resources.  Besides, since the channel resources of the transmission medium are distributedly managed by plural video transmitters or video receivers, the channel resources are dynamically allocated, and the images of video input means 1011 -101n and video output means 1031 -103n can be connected to these channel resources as well.

Title: Method and equipment for inspecting floating margin of magnetic disc drive
Inventor: SHIMADA MINORU
IPC: G11B5/84
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To perform inspection at high accuracy while mounting a magnetic disc drive by placing the magnetic disc drive in a chamber under a specified atmospheric pressure, recording a contact inspection signal and reproducing it as a reproduction signal output, repeating the recording/reproduction while lowering the atmospheric pressure and determining the difference between a specified atmospheric pressure and an atmospheric pressure, where the variation of reproduced signal output with respect to the atmospheric pressure is substantially zero, as a floating margin. SOLUTION: After a floating margin inspection data generated from the write signal generation circuit 5 of a magnetic disc drive 1 is written on a medium in an HDA 2, the data is read out by an R/W circuit 4 and the output of a reproduction signal (a) is measured. The atmospheric pressure is then lowered sequentially, and the reproduction signal (a) is measured under each state. Floating amount decreases as the atmospheric pressure lowers but the reproduction signal (a) is increased because the magnetic spacing is decreased. At the moment of time when the magnetic spacing becomes 0, the reproduction signal (a) is no increased even if the atmospheric pressure is lowered furthermore. At the moment of time when the magnetic spacing is saturated, floating margin is 0 and the head touches the disc.

Abstract: PURPOSE:To improve the welding reliability of a sealed battery in which hermetic sealing is adopted by increasing the energy density of an area of which a laser beam is irradiated. CONSTITUTION:After a negative electrode 2, a separator 4, a lower lid 10, a positive electrode 3 and an upper lid 9 are inserted in a battery case 1, a battery lid 5 having an annular groove 5a with a semi-circular sectional surface on its outer periphery is attached to the opening of the battery case 1. After that when the battery case 1 and the battery lid 5 are fused by irradiating a laser beam 12 on the groove 5a from above, owing to the converging effect of the groove 5a, the energy density of the bottom of the groove 5a becomes very high producing a deep molten pool 11 a shown in the figure, thereby firmly welding the battery case and lid 1 and 5 together. A highly air- and liquid-tight welding is obtained over the eitire circumference by scanning the laser beam 12 in circular form along the groove 5a by rotating the battery at a proper rotating speed.
