A forceps channel tube is composed of a tube body, a reinforcing tape and a protective layer. The reinforcing tape includes a reinforcement layer and an adhesive layer. The reinforcement layer has a plurality of strip-shaped high and low rigidity portions arranged alternately. The reinforcing tape is wrapped around an outer surface of the tube body in a manner that each of the high and low rigidity portions encircles the tube body along the circumferential direction, and fixed thereto by the adhesive layer. The reinforcing tape provides the tube body with rigidity anisotropy that increases a first rigidity against force in a radial direction of the tube body to exceed a second rigidity against bending force.

There is provided an electronic device for receiving an input data signal and an input clock signal that indicates a timing to obtain the input data signal. The electronic device includes a first adjusting section that adjusts a phase difference between the input data signal and the input clock signal so as to be equal to a first phase difference, and outputs the resulting signals as a first data signal and a first clock signal, a phase varying section that outputs a second clock signal having a designated phase difference with respect to the first clock signal, and a second adjusting section that adjusts the phase difference of the second clock signal with respect to the first clock signal so as to be equal to a second phase difference, based on a result of obtaining the first clock signal at a varying timing of the second clock signal.

Disclosed is a process for the preparation of aromatic hydroperoxides comprising contacting two liquid phases comprising an oily phase containing an aromatic compound having a secondary alkyl group and a basic aqueous phase under agitation with a molecular oxygen-containing gas in the presence of a copper compound catalyst such as an inorganic salt or organic acid salt of copper, thereby to oxidize the aromatic compound to a corresponding aromatic hydroperoxide, wherein the liquid phase catalytic oxidation is carried out while maintaining the catalyst concentration in the liquid phases at 0.005 to 10 ppm as the copper atom and the pH value of the basic aqueous phase at 7.6 to 10. According to this process, by adoption of the above-mentioned specific catalyst concentration and pH value in combination, the rate of oxidation of the aromatic compound is increased and the selectivity to the hydroperoxide is improved.
