In a foldable cellular phone, a cross key is provided on an operating surface of a second casing and a side right-and-left key having the same function as two direction keys of the cross key is provided on one side surface of the second casing. Further, a side up-and-down key having the same function as the other two direction keys of the cross key is provided on a side surface of a first casing that is positioned on the same side as the side right-and-left key when the foldable cellular phone is folded in such a way that the display section faces to the outside.
摘要:
A magnet for an NMR an analyzer includes a superconductor coil which is operated under a permanent current mode so as to generate a magnetic field in a space surrounded by the superconductor coil, and which enables a sample to be inserted into a measurement space in the magnetic space for analization. The superconductor coil includes a first access port for enabling access to the measurement space and a second access port for enabling insertion of the sample into the measurement space in a direction different from a direction of the first access port. An effective diameter of the first access port is larger than an effective diameter of the second access port when the effective diameters of the first and second access ports are defined as a diameter of a cylinder that is insertable into the first and second access ports.

A nuclear magnetic resonance measuring apparatus includes an NMR probe head equipped with an NMR receiver coil and an irradiation coil, a preamplifier, for amplifying the NMR signal received by the NMR receiver coil, a coil cooling heat exchanger, for exchanging heat between the NMR receiver coil/irradiation coil and coolant, a preamplifier heat exchanger for exchanging heat between the preamplifier and the coolant, and a cooling device capable of cooling and compressing the coolant. Further, a first transfer tube is provided for transferring the coolant from the cooling device to the probe head, a second transfer tube for transferring the coolant from the probe head to the cooling device, a third transfer tube for transferring the coolant from the cooling device to the probe head, and a fourth transfer tube for transferring the coolant from the probe head to the cooling device.

In a nuclear magnetic resonance spectrometer, the shape of a detection coil is changed from a conventional cage type to a solenoid type of higher sensitivity. Accordingly, differing from the conventional superconductive magnet of multilayer air core solenoids, a superconductive magnet is right and left divided to split magnets for generating 11 T, preferably, 14.1 T in the horizontal direction, and the magnetic field uniformity is set to 0.001 ppm or less and the temporal stability is set to 0.001 ppm or less.

It is one object of a grinding machine and a grinding fluid supply-nozzle therefor according to the present invention to supply grinding fluid to a moving grinding point reliably, even if the surfaces of a grinding wheel is abraded up.A wheel head 5 advances/retracts to a workpiece. A grinding wheel G is carried rotatably by the wheel head 5 and grinds an eccentric portion W of the workpiece. A grinding fluid supply-nozzle 50 supplies grinding fluid to a moving grinding point K where the grinding wheel G contacts the eccentric portion W of the workpiece. The grinding fluid supply-nozzle 50 is made from a curve portion 53, an opening 51 and a straight portion 52 between the curve portion 53 and the opening 51. The grinding fluid supply-nozzle 50 spouts the grinding fluid to a grinding fluid supply point Pc upstream the grinding points K and Ks, even in the case that the grinding wheel G has been abraded up. Besides, the angle between the tangent of the grinding fluid supply point Pc and the grinding fluid spouted from the grinding fluid supply-nozzle 50 is smaller than a right angle.

摘要:
An apparatus for continuous dissolution comprising a dissolution portion for dissolving a gas into a main stream liquid, which comprises a flow meter measuring the flow rate of the main stream liquid and outputting a signal of the value obtained by the measurement and a mechanism for controlling the flow rate which controls the amount of supply of the gas based on the input signal; and a process for continuously dissolving a gas into the main stream liquid, wherein the amount of the gas is controlled based on the flow rate of the main stream liquid. Since a solution having a constant concentration can be obtained with stability even when the flow rate of the main stream liquid changes, cleaning water or surface treatment water used for electronic materials which particularly require a precisely clean surface can be supplied without loss.
