Title: Nonaqueous electrolyte battery
Inventor: OZAKI YOSHIYUKI
IPC: H01M10/052
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To suppress the abrupt temperature rise of a battery and secure safety by the effect of a high-molecular fine porous membrane separator even when an internal short circuit occurs in the battery. SOLUTION: The air permeability value of a separator 5 must by 700-1200sec/100cc at the room temperature. When it is below 700sec/100cc, the oxygen cutoff effect is insufficient. When it exceeds 1200sec/100cc, the ionic migration speed is lowered and the high-rate charge/discharge characteristics are lowered. The air permeability value must be 700-3000sec/100cc when the separator 5 is held for 3min at 85 deg.C in the atmosphere, and it must be 10000sec/100cc or above when the separator 5 is held by 3min at 95 deg.C. When the temperature for the air permeability value of 10000sec/100cc exceeds 100 deg.C, it is difficult to suppress the abnormal heat at the time of an internal short circuit. When the air permeability value becomes 10000sec/100cc or above below 90 deg.C, the performance deterioration is remarkable.  The tensile elongation percentage in the width direction of the separator 5 must be 1000-3000%, and its film thickness must be 15-40μm.

Title: Optical information recorder
Inventor: KAMIJO NORIYUKI
IPC: G11B7/00
Filed: 1985-12-17
Abstract: PURPOSE:To scale down a device and to cut down its cost by fixing an optical information recording medium on a drive means including a spindle motor so that said medium cannot be removed and arranging the recording medium in a space having a dust-prevention effect. CONSTITUTION:The optical information recording medium 2 is placed in the recessed part of a hub 10 secured on the shaft 8 of a spindle motor 30, and pressurized and fixed by a clamp plate 3 and a claw screw 4 between them. In order to prevent the entry of dust in a machine frame 1, a screw for fixing the cover 36 of the device is tightened by a packing 35, and the packing 35 is brought into pressure-contacted with the frame 1 and the cover 36. A known control circuit irradiates laser light from a laser diode 20 in accordance with a signal, and the light is focused on the recording layer 2b of the medium 2. Then the recording layer 2b is heated more than a Curie point. A magnetic field in the part is inverted by the magnetic pole of a bias coil 16, and information is recorded as a bit about 1mum in length in the recording layer 2b. Accordingly a distance A from the recording layer 2b to the bias coil 16 is short, and a small coil suffices accordingly.

Title: Water quantity adjuster
Inventor: HAMADA MAKOTO
IPC: F16K13/00
Filed: 1988-11-11
Abstract: PURPOSE:To make water quantity adjustment with a small torque without any restriction on the water incoming direction by furnishing a zigzagged leaf spring or a spiral spring so that the pitch space becomes perpendicular to the water stream, dimensioning the pitch space so as to admit passage of water, and expanding or contracting it. CONSTITUTION:A through-hole 22 is provided in an intermediate cylinder 2 situated inside the valve body 1 of a water quantity adjuster and put in communication with a water inlet hole 91 and outlet hole 16. A spiral spring 7 is installed at a step 12 and fixed to a spindle 3. A servo motor 6 is secured to one end of this spindle 3 with a key 5. When rotation of this spindle 3 by the servo motor 6 winds in the spiral spring 7 to lessen its pitch, the water passing area of the pitch space decreases to cause decrease in the amount of water passage. Slackening will increase this amount. This may be so constructed that a zigzagged leaf spring is pressed and allowed to make compression or elongation. This permits stepless adjustment of the water passage amount with no restriction on the water incoming direction, wherein the valve sliding torque is reduced and noise suppressed.

Abstract: PURPOSE:To use a material which is inexpensive and easy to assemble and to make the work of connecting a tap lead to a fixed contactor easier by fixing odd numbered leads and even numbered leads of an identical phase to each other. CONSTITUTION:Odd numbered takeout leads 15 and even numbered takeout leads 16 of the same phase are brought into close contact with each other and fixed by a tie strap 17 provided on a takeout lead 14.
