Title: Manufacture of non-woven fabric having metal film
Inventor: TANIGUCHI TADATAKE
IPC: B32B15/14
Filed: 1990-08-09
Abstract: PURPOSE:To make it possible to easily manufacture non-woven fabric, which has enough amount of metal film and is excellent in flexibility and cushioning properties by a method wherein the non-woven fabric, which develops bulk developing properties by heating treatment, is heat-treated so as to increase the bulk of the non-woven fabric and, after that, metal is vapor-deposited on at least one of both sides of the non-woven fabric. CONSTITUTION:By heat-treating non-woven fabric, which shows bulk developing properties by heating treatment, is heat-treated so as to increase the bulk of the non-woven fabric in order to have voids, the volume of which is several times as large as the voids in the initial non-woven fabric, in its interior or turn into the state that the distance between respective fibers consisting of the non-woven fabric is widened. By vapor-depositing metal on the non-woven fabric under the state just mentioned above, deposited metal covers not only the surface layer of the non-woven fabric but also the fibers in its interior, resulting in enlarging the covering area of the metal film formed on the surface of the fibers. As the mold, when excellent electrical conductivity is requested, aluminum, silver, copper, nickel of the like is preferably used. Further, metal film may well be formed in multiple layers by vapor- depositing metals, which are different from each other, by a plurality of times. Or vapor deposition may well be applied not only on one side but also on both sides of tire non-woven fabric.

Title: D/a converter
Inventor: ISHIDA HIDEKI
IPC: H03M1/74
Filed: 1989-08-18
Abstract: PURPOSE:To decrease the circuit scale of a current source cell without incurring the deterioration in the performance by constituting the D/A converter of a transistor(TR) a different in polarity from a TR whose gate is fixed to a prescribed voltage. CONSTITUTION:When a P-channel TR 34 is turned off and a P-channel TR 33 is turned off, a current flowing to a switch is interrupted, a voltage VS at a node NA rises to increase the gate-source voltage VGS of a P-channel TR 23. Thus, the P-channel TR 23 is turned on and an output current IOUT is outputted. Moreover, when the gate of the P-channel TR 23, the P-channel TR 23 or 34 receives an L level voltage, the level VS is dropped nearly to a GND level and no current IOUT flows. Thus, the current source cell 31 is constituted of a current source 22 and the 4 P-channel TRs 23, 32-34.

IPC: H04M11/00
Filed: 1993-08-30
Abstract: PURPOSE:To extend the service life of a battery by switching a voltage from the battery into a voltage converted into a regular voltage of the equipment so as to operate the equipment in the specific operation of the equipment. CONSTITUTION:A voltage of a battery 1 is selected to be a voltage lower than a regular voltage of the equipment and the equipment is operated by the low voltage normally. A DC conversion means 2 converts the voltage of the battery 1 into a regular voltage of the equipment to provide an output of the regular voltage. When a specific operation detection means 3 detects the specific operation of the equipment, the means 3 activates a voltage changeover means 4 for a period when the specific operation is detected to switch the DC voltage applied to the equipment from the voltage of the battery 1 into the regular voltage outputted from the means 2. Thus, the service life of the battery is extended by switching the voltage outputted from the battery into the regular voltage of the equipment in the specific operation while applying the low voltage to the equipment in the normal state.
