In a normal state before active/standby switching between an active system and a standby system, in an AAL2 cell assembling/disassembling processor 11 as the standby system, an ATM cell transmission/reception control portion 6 sends ATM cells to an AAL2 cell disassembling portion 8 and an AAL2 cell assembling portion 9. Therefore, in the standby system also, AAL2pf assembling buffer data and cell-to-cell stretch handover data are continuously held. When a switching start request is supplied from a host unit 1 and active/standby switching is carried out, a sequence number alone is transferred from the active system to the standby system.

An open tubular capillary column, for high-speed micro liquid chromatography made of a glass tube of the inner diameter not more than 0.10 mm, having the net inside capacity not less than 0.5 .mu.l, the inner surface of which hollow glass tube being chemically bonded, in order to provide a stationary phase there, with at least one silane or its derivative such as octadecylsilane to form a polymeric layer. This invention includes the manufacturing method of such a column.
摘要:
A system for and a method of providing an eluent composed of two different kinds of liquids being mixed at a set concentration and further a time varying concentration or mixing ratio, comprising (a) a step for transferring each of the two liquids by sucking under low-pulsation to on-off valves; (b) a step for periodically controlling the operation of the on-off valves; (c) a step for controlling the amount of each liquid supplied to the mixing region during each period of valve operation; (d) a step for substantially sucking the eluent formed by the above steps in the mixing region for discharging or supplying the same under the same low-pulsation, whereby a mixing of the two liquids under an atmospheric or a low constant pressure, can be effected and a supply of an eluent having a precisely controlled time varying concentration of each liquid can also be effected, and a system for providing such an eluent. Further a system for preparing such an eluent composed of more than two different kinds of liquids can be provided.
摘要:
A mobile communication system including: a terminal, a movement-origin base station to which the terminal connects before movement of the terminal; a movement-destination base station to which the terminal connects after movement of the terminal; and a higher-order apparatus that has the movement-origin base station and the movement-destination base station under its control. Control information for voice encoding is set in advance in the movement-origin base station and the movement-destination base station, the movement-origin base station includes the control information of its own station in a first message and transmits the first message to the higher-order apparatus, and the higher-order apparatus includes the control information of the movement-origin base station in a second message and transmits the second message to the movement-destination base station.
摘要:
A semiconductor device has a semiconductor substrate, an insulating film, a semiconductor element and a resistance element. The semiconductor substrate has a first trench. The insulating film covers an inner surface of the first trench. The semiconductor element has an electrode. The resistance element is electrically connected to the electrode to form a resistance to a current flowing through the electrode, and is arranged in the first trench with the insulating film therebetween. Thereby, the semiconductor device can have a resistance element that has a small footprint and can pass a large current with high reliability.

An electronic calculator comprises a keyboard for receiving numerical data, storage registers for storing the numerical data, a processor unit for processing the numerical data stored in the storage registers, a display unit for visually displaying the numerical data, a blocking circuit for blocking the visual display of a computed result from the processor unit, and a releasing circuit to discontinue the blocking of the visual display of the result, thereby causing the operator of the calculator to not know the result until receiving instructions.
