A cutting insert having excellent toughness as well as wear resistance is provided comprising a substrate consisting of a sintered hard metal or alloy such as cemented carbides and a coating film provided thereon consisting of a material having a higher hardness than the substrate, characterized in that the coating film near the cutting edge is continuously made thinner or removed toward both the rake face and flank face.
摘要:
A circuit interrupter which comprises, in a compartment defined in an electrically insulating housing, a pair of separable contacts defining, when separated, an arcing region therebetween, and an operating mechanism, including a tripping unit and an operating handle, for opening and closing the separable contacts. The housing which includes an electrically insulating bottom wall has a gas exhaust passage having an inlet opening in the inner surface of the housing. The inlet of the gas exhaust passage is located in the bottom wall at a position effective for exhausting an arced gas generated in the arcing region without contacting the operating mechanism.

Provided is a color-developing composition for recording materials having a superior heat resistance. The color-developing composition is a reaction composition containing a mixture of compounds represented by formula (III) obtained by reacting a dihydroxydiphenylsulfone derivative represented by formula (I) with a dihalide represented by formula (II) X—Y—X (II), wherein, in a composition where the content of a compound with n=1 in said reaction composition is from 5 to 80% by mass of the total solid content of the composition, at least 10% by mass of the compound with n=1 is a crystalline material.
摘要:
Provided is a recording material with a superior heat resistance and having a low content of a dihydroxydiphenylsulfone derivative, and a color-developing composition for producing the recording material. With the use of this color-developing composition, a recording material with a superior heat resistance at the background part can be provided and the content of a dihydroxydiphenylsulfone derivative, such as 4,4′-dihydroxydiphenylsulfone, in the color-developing composition can be reduced to 2% by mass or less, or further to 1% by mass or less.
摘要:
A digital signal processor includes a component for processing a digital signal, a power line for supplying a power to the component, and a decoupling capacitor connected between the power line and a ground. The decoupling capacitor has an equivalent series resistance larger than zero and not larger than 25 mΩ at 100 kHz and an equivalent series inductance larger than zero and not larger than 800 pH at 500 MHz. This digital signal processor does not generate a lot of digital noise, and has a small, thin size.
