Title: Recording information reproducing device
Inventor: UNNO HIROJI
IPC: G11B21/08
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To reduce the retrieval time of an optical disk different in track interval by calculating the steps of movement with a preset track interval and correcting and recording the track interval using the difference of the calculated steps from the number of tracks after movement. SOLUTION: A control microcomputer 9 calculates the number of steps of a stepping motor 7 required for moving an optical pickup 3 from the present time information position to the aimed time information position using the preset value of track interval, linear velocity and time information. The stepping motor 7 actuates the optical pickup 3 by a calculated number of steps and moves it to the vicinity of the aimed time information position. At this time, the control microcomputer 9 reads the time information of the optical disk 1 at this position, calculates and corrects the number of difference tracks to the aimed time information position to store it into the memory 10. In the succeeding information retrievals, the necessary number of steps is calculated using this correction to move the optical pickup.  By this, the time for retrieving information can be shortened for an optical disk having different track intervals.

Title: Memory device
Inventor: ITO SHINICHI
IPC: H01L27/11
Filed: 1988-08-24
Abstract: PURPOSE:To reduce parasitic capacitance between adjacent bit lines, prevent the patterning being required for the bit lines from being fined, and improve the wiring yield by forming two adjacent bit lines by using mutually different layers. CONSTITUTION:An aluminum wiring layer 5 of a first layer and an aluminum wiring layer 7 of a second layer respectively constitute bit lines. Each bit line is alternately formed in the extending direction by the first aluminum wiring layer 5 and the second aluminum wiring layer 7. Averaged electric conditions of the first aluminum wiring layer 5 and the second aluminum wiring layer 7 turn to the electric condition of each bit line, thereby preventing the generation of difference of electric conditions between the bit lines. Since the aluminum wiring layer 7 of the second layer does not exist at all on the aluminum layer 5 of the first layer, no troubles occur even if the aluminum wiring layer 5 of the first layer is thickened. As a result, the aluminum wiring layer 5 of the first layer can be thicker than the usual one, so that the resistance to electromigration can be improved.

Title: Heat energy storage medium and heat energy storage and recovery therewith
Inventor: SHIMON ANDORIYUU TOOMASU
IPC: C09K5/06
Filed: 1984-10-08
Abstract: A thermal energy storage medium comprising a hydrophilic polysaccharide supporting an inorganic salt that is capable of transforming from one phase to a less hydrated phase absorbing latent heat, and releasing this latent heat upon the reverse transformation. The polysaccharide, preferably Xanthan Gum, may be incorporated in concentrations of 0.05% to 3% together with a nucleating agent in order to form a material that transforms when cooled back to the transformation temperature, or in greater concentrations of 1% to 5% without a nucleating agent to form a material that may be cooled below the transformation temperature without transformation taking place, and stored at ambient temperature whilst still storing the latent heat until activated.The medium is gelled in the less hydrated phase and in some embodiments the gel is pseudoplastic thus enabling it to be poured into chambers of an energy storage device, and then regain its original viscosity at rest.

Title: Local oscillator circuit
Inventor: OMORI MANABU
IPC: H03L7/18
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To obtain a low-phase-noise local oscillator circuit which has simple constitution and is suitable specially for a satellite communication by grounding a resistance element between a loop filter and a voltage-controlled oscillator through a capacitor. SOLUTION: A phase comparator 3 built in a PLL frequency synthesizer 1 compares the phase difference of a local oscillation signal as the output of a VCO 6 which has its frequency divided to 1/N by a programmable counter 2 with the phase of the signal of a reference oscillator 4. An output voltage corresponding to their phase difference after passing through the loop filter 5 is supplied as a control voltage to the VCO 6 through an RC series circuit consisting of a resistor R and a capacitor C. Consequently, this loop is repeated so that the 1/N frequency division result of the local oscillator frequency of the VCO 6 matches the frequency of the reference oscillator 4. Therefore, phase noise characteristics of the local oscillator signal can be greatly improved only by adding a simple circuit consisting of the resistor R and capacitor to the input side of the VCO 6.
