Abstract: A method of retreading a tire casing includes the step of disposing a cured rubber tread on a carcass with a layer of hot-melt material interposed between the tread and the carcass. The method continues with the step of rollering the tread by means of at least one roller with a width (r) that is less than a width (b) of the tread.

Abstract: A label rewind machine counts labels on a label roll having an elongated web with labels attached. The rewind machine has an unwind spindle and a rewind spindle, and a first label sensor and a second label sensor. The label roll is placed on the unwind spindle, and the web is threaded through the first and second sensors and attached to the rewind spindle, creating a web path. As the web is drawn along the web path, each sensor detects the presence or absence of a label on the web proximate that sensor and generates an electronic signal. Together, the sensors generate a specific quadrature sequence dictated by the presence of labels on the web. If the detected sequence mimics a selected sequence, the rewind machine records a unitary count of one label. The label count is indexed by one each time the rewind machine detects the selected sequence.

Abstract: The present invention relates to silicon-compound-coated fine metal particles, with which surfaces of fine metal particles, composed of at least one type of metal element or metalloid element, are at least partially coated with a silicon compound and a ratio of Si—OH bonds contained in the silicon-compound-coated fine metal particles is controlled to be 0.1% or more and 70% or less. By the present invention, silicon-compound-coated fine metal particles that are controlled in dispersibility and other properties can be provided by controlling the ratio of Si—OH bonds or the ratio of Si—OH bonds/Si—O bonds contained in the silicon-compound-coated fine metal particles. By controlling the ratio of Si—OH bonds or the ratio of Si—OH bonds/Si—O bonds, a composition that is more appropriate for diversifying applications and targeted properties of silicon-compound-coated fine metal particles than was conventionally possible can be designed easily.

Abstract: A method and a device for detecting the oil level in a hydraulic pulse unit at an impulse type power wrench, wherein the pulse unit comprises an oil filled pulse chamber, a motor driven inertia drive member, and a kinetic energy receiving member connected to an output shaft and intermittently coupled to the inertia drive member via an oil cushion to receive kinetic energy from the inertia drive member during repeated energy transfer phases.

Abstract: A method for modifying a fine particle dispersion liquid has excellent dispersibility and dispersion stability. In this method for modifying a fine particle dispersion liquid having improved fine particle dispersibility, impurities included in an agglomeration of fine particles contained in the fine particle dispersion liquid are released into the dispersion liquid by applying physical energy to the agglomeration and performing dispersion processing for dispersion into particles that are smaller than the agglomeration of fine particles. The impurities are removed from the dispersion liquid by means of a removal unit provided with a filtration membrane before reagglomeration is caused by the impurities.
