摘要:
A noise canceller includes an input terminal for receiving an input signal containing a received signal and a first noise signal generated by a noise source, a first delay unit for delaying the input signal, a pick-up antenna for receiving a second noise signal generated by the noise source, a cancel-signal generator for generating a noise-canceling signal based on the second noise signal, and a combiner for combining the delayed input signal and the noise-canceling signal so as to cancel the first noise signal contained in the input signal, and outputting the received signal. The noise canceller can include a second delay unit for delaying the second signal instead of the first delay unit or in addition to the first delay unit. This noise canceller cancels the noise signal generated by the noise source, thereby providing an electronic device having a preferable receiving sensitivity.

A high-density N-type diffusion layer 116 formed in a separation area 115 makes it possible to reduce a collector current flowing through a parasitic NPN transistor 102. Thus, a normal CMOS process can be used to provide a driving circuit and a data line driver which make it possible to improve resistance to possible noise occurring between adjacent terminals, while controlling a chip size.

A wound laminate obtained by laminating a plastic film composed of an aromatic polycarbonate comprising bisphenol A as an aromatic dihydroxy component, and a protective film composed of an aromatic polyester, using an intervening adhesive having a weak adhesive strength of 3-50 gf (0.0294-0.49 N), and winding the laminate. The wound laminate is used as a transparent protective layer (protective film) for an optical disk to fabricate a film surface side-incident optical disk.

The wire electric-discharge machining apparatus is provided with an inter-pole voltage correction unit 109 which corrects a voltage corresponding to an inter-pole voltage according to a correction coefficient which increases with an elongation of discharge stop time. A corrected voltage corresponding to the inter-pole voltage output from the inter-pole voltage correction unit 109 is given to a control unit 106 to allow a wire electrode 101 and a workpiece 102 to relatively move according to the corrected voltage corresponding to the inter-pole voltage.

A steroid derivative is used as a blood flow amount-improving agent, which is blended with a cosmetic preferably in a ratio of 0.000001 to 10% by weight with respect to a total amount of the cosmetic.
摘要:
A double link type suspension system having an extension member for movably connecting the upper section of a knuckle and an upper control arm movably connected to the side of a vehicle body. A rotatable joint mechanism is provided between the knuckle upper section and the extension member and includes a cylindrical member fixed to the extension member. The axis of the cylindrical member is aligned with an axis line passing through a joint between the lower section of the knuckle and a lower control arm movably connected to the vehicle body side. A pivot shaft fixed to the knuckle upper section is disposed inside the cylindrical member and rotatably supported through two deep groove ball bearings disposed between the pivot shaft and the cylindrical member, thereby reducing jointing error between the knuckle and the extension member thus reducing camber angle error.

A high-frequency power source device includes switching element groups having a configuration in which a plurality of switching elements turned on/off cyclically are connected in parallel. One parallel connection terminal of the switching element group is connected to a positive electrode terminal of a DC power source, and one parallel connection terminal of the switching element group is connected to a negative electrode terminal of the DC power source. Respective other parallel connection terminals of the switching element groups are connected via a reactor. A pulse voltage that appears at opposite ends of the reactor due to a cyclic on/off operation of the switching element groups is applied to a load through a coaxial cable and a matching circuit.

A rust preventive oil composition is provided, which includes: (A) a base oil that is at least one oil selected from a mineral oil and a synthetic oil; (B) 0.1 to 10% by mass of water based on a total mass of the composition; and (C) one or more specific rust preventive additives selected from the group consisting of a sarcosine-type compound, a nonionic surfactant, a sulfonate salt, an ester, an amine, a carboxylic acid, a fatty acid amine salt, a carboxylate salt, paraffin wax, a salt of oxidized wax, and a boron compound, wherein the rust preventive oil composition has a kinetic viscosity of 20 to 100 mm2/s at 40° C. The rust preventive oil composition can suppress rust development over a long period of time even when there remains a rust-causing agent, which adheres to the metal parts assembled by bare hands, such as steel sheets, bearings, steel balls, and guide rails.
