Title: Manufacture of hardly workable metallic plate of high purity
Inventor: OE JUNYA
IPC: B22F3/24
Filed: 1985-07-22
Abstract: PURPOSE:To increase the purity of a hardly workable metallic plate by simple operation by evenly irradiating an electron beam on each side of the plate to partially melt the plate and by volatilizing and removing volatile impurities during the melting. CONSTITUTION:An electron beam is irradiated on each side of the plate of a hardly workable metal such as Mo or W formed by melting or sintering to partially melt the plate by a prescribed depth from the surface.

Title: Enclosed type lead storage battery
Inventor: YAMASAKA KOICHI
IPC: H01M50/528
Filed: 1987-06-29
Abstract: PURPOSE:To prevent the decrease of capacity after a long preservation by filling a water-repellent resin whose critical surface tension is less than 73dyne/ cm<2> to a tray-formed member of lead or a lead alloy whose recession faces the electrode plate side at the top of poles which connect the neighboring cells in series. CONSTITUTION:Since the surface tension of water is 73dyne/cm<2>, the water hardly wets the surface of a resin whose critical surface tension is less than 73dyne/cm<2>. And by filling a resin 7 whose critical surface tension is less than 73dyne/cm<2> at the tray-formed member of lead or a lead alloy 6 facing its recession to electrode plates 1 and 2 side at the top of poles 4 and 5, the water hardly wets the periphery of the poles 4 and 5, because the upper parts of the poles 4 and 5 are buried in the resin 7. That is, since the liquid contact of the positive pole and the negative pole 4 and 5 is prevented by the water- repellent property of the resin 7 even though a dew condensation is produced owing to the rise and the fall of the temperature when the battery is left for a long time, the self-discharge from the liquid contact is prevented. A decrease of the capacity during a long preservation can be prevented accordingly.

Title: Display device in finder of camera
Inventor: MURAKAMI HIROYASU
IPC: G02F1/13
Filed: 1981-10-09
Abstract: PURPOSE:To display data partially in a high contrast and, partially in a low contrast simultaneously, by displaying characters, patterns or the like outside or inside the visual field of a finder by a liquid crystal. CONSTITUTION:The light passing through a light transmission face 3a corresponding to an information display aperture 19 of a focusing screen 3 passes through a polarizing plate 6 and a G.H (guest.host) liquid crystal 5 and is visually recogniged through this aperture 19 with a pentagonal prism 1 and an eyepiece lens 2 by a photographer. The proper-contrast pattern display of an aperture 18 for photographic visual field of the focusing screen 3 is superimposed to the object image formed on a diffusing focal plane corresponding to this aperture 18 and is seen through a finder system. These patterns 10-15 do not require a high contrast. Since a display pattern 17 outside the photographic visual field requires a high contrast, this display is obtained by the guest host type (G.H.) liquid crystal.

Title: Controlling circuit for speed of dc motor
Inventor: FURUTA MASAMI
IPC: H02P7/288
Filed: 1979-12-13
Abstract: PURPOSE:To improve the characteristic of torque at low speed by inserting a reverse series circuit of a flywheel diode and a voltage nonlinear element in between the terminals of the motor and thereby detecting earlier the counter electromotive voltage of the motor. CONSTITUTION:A commercial power source 1, which is subjected to fullwave rectification, is added to the DC motor 2, while a transistor Tr1 subjected to continuity angle control is connected in series therewith. Moreover, so as to detect the counter electromotive voltage, a Zener diode ZD1 is connected in series reverse to the flywheel diode D5 and to the diode ZD1 are further connected partial pressure resistance circuits R1 and R2. Furthermore, a transistor Tr2 whose power source is rectification voltage during the period when the motor 2 is off is provided, whereby the output of the partial pressure resistance circuits R1 and R2 is largely amplified at the time of low speed and Tr1 is controlled through comparison by indented reference voltage and a differential amplifier. Accordingly, the detection of the counter electromotive voltage can be made earlier and thus the torque equivalent to that at high speed can be generated even at low speed.

Title: Method for evaluating off-track characteristic of magnetic recording medium
Inventor: YASUI MASAHIKO
IPC: G11B5/84
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To measure and evaluate the off-track characteristic of a magnetic recording medium even in a high density recording area which exceeds the reproducing performance of a recording and reproducing head by reproducing the pattern of a signal recorded on the magnetic recording medium using a magnetic force microscope and measuring the off-track characteristic of the magnetic recording medium from the width of the reproduced pattern. SOLUTION: The reproducing pattern of a magnetic force microscope of a magnetic recording medium indicates the track width direction (the radial direction of the magnetic recording medium) and a space between the tracks to reach other in an ordinate and the track length direction (the circumferential direction of the magnetic recording medium) in an abscissa. By measuring the width of a track from the obtained reproducing pattern, the off-track characteristic of the magnetic recording medium can be obtained. Thus, even without a recording and reproducing head having reproducing performance in a desired high recording density area, the off-track characteristic is measured to evaluate the magnetic recording medium and this method can be utilized for the development of the magnetic recording medium.
