Patent JP-H04366427-A (JP)
Title: Optical disk device
Inventor: WADA MITSUNORI
IPC: G11B21/02
Filed: 1991-06-12
Abstract: PURPOSE:To enable a movable portion to be balanced and at the same time weight of a device to be reduced by allowing a support member to be moved freely in a same direction as a traveling direction of the movable portion and interlocking the above movable portion to the support member so that they move in opposite directions. CONSTITUTION:At the time of reproduction and when moving to a desired information recording portion at high speed, a drive force is given to a lens- retaining member 23 by a magnetic drive circuit K when a supply current to a coil 26a for tracking is changed, thus enabling a traveling base 24 to slide on a guide axis 27. Therefore, the lens-retaining member 23 moves in lower direction and reads a memory information on a disk. At this time, a magnetic drive circuit K moves in opposite direction from a movable portion U and operates as a balancer so that the movable portion U travels smoothly. A traveling distance of the magnetic drive circuit K is small in reference to that of the movable portion U, thus preventing an interlocking member 28 from hitting against a spindle motor M when recording or reproduction operation of an outermost periphery of the disk are being made.

Abstract: PROBLEM TO BE SOLVED: To drive two light shielding means by one driving means by installing an energizing means for a 1st light shielding means and a holding means for the 1st light shielding means and a driving means for performing 1st and 2nd operations. SOLUTION: When the holding release operation of the 1st light shielding means (1st and 2nd shutter blades 13 and 14 and a 1st driving ring 2) held by an opening starting lever 7 in a closed state is performed by a stepping motor 10, the 1st light shielding means is operated to be open by the energizing force of a spring 6. Thereafter, the 2nd light shielding means (3rd and 4th shutter blades 29 and 30 and a 2nd driving ring 26) are driven to be closed by the stepping motor 10. That is, the spring 6 and the open-starting lever 7 are made to play a role in the conventional part of the 1st light shielding means driving means and also the stepping motor 10 is made to perform the part of driving the closing operation of the 2nd light shielding means after starting the opening operation of the 1st light shielding means.  Thus, the number of driving means (stepping motor) 10 can be reduced to one, then, the control circuit can be simplified.

Abstract: PURPOSE:To prevent closing of a cooling pipe by using manganese dioxide as adsorption filter medium and providing a backwashing water supplying device and a backwashing water discharging device. CONSTITUTION:After the cooling water discharged from a battery body 1 is separated to gas and liquid by a gas-liquid separator 2, said water flows through a valve 3, is pressurized by a pump 4 ad is supplied to a high-temp. adsorption column 11. The corrosion products of heavy metals are removed by the manganese dioxide 10 in the high-temp. adsorption column 11. The treated liquid is supplied again to the battery body 1 via a valve 5. The liquid in a backwashing water tank 12 is subjected to flow rate regulation with a flow meter 16 as an index and is passed through the high-temp. adsorption column 11 when the clad-like heavy metal products stick and deposit to the manganese dioxide after the continuous treatment. The treatment column is thus backwashed while the liquid is allowed to flow through the filter media. The treatment is executed stably over a long period of time in this way without entailing heat losses.

Title: Manufacture of superconducting product
Inventor: HASEGAWA SHOICHI
IPC: H01B13/00
Filed: 1987-07-07
Abstract: PURPOSE:To improve superconducting characteristic by filling a metallic container with superconductive powder and solidifying the powder by applying pressures either by sealing a pressure medium in a pressure vessel or by causing an explosion within the pressure vessel. CONSTITUTION:Filling a metallic pipe 1 with superconductive powder 2, both ends of the pipe 1 is sealed to contain the powder 2. Housing the pipe 1 in a pressure vessel 3, pressure is applied within the vessel 3 by pressurizing with either hydrostatically or hydraulically, or instantaneously by explosion within the vessel 3. This pressurization causes the powder 2 to bind tightly. When the pipe 1 filled wit the superconductor is subjected to a roll process and its diameter is reduced to a required value, the pipe becomes a superconducting wire having strong bond between the particles and a high bulk density. This improves the superconducting characteristic such as critical current density.
