摘要:
Despreading means 10 despreads a pilot signal included in a first received signal 1. Strength determination means 15 determines the strength of the despread pilot signal. Integration control means 16 determines the integration interval used by integration means 13, from the strength of the received pilot signal. The differences in strength detected by strength difference detection means 12 are added together by the integration means 13 over the period of time decided by the integration control means 16. The integration interval used by the integration means 13 is made changeable according to the receiving environment. Accordingly, when there is the superior receiving environment, there is reduced the load imposed on the integration means 13 when the integration means 13 performs the processing operations. Therefore, there can be realized a superior CDMA receiver phase tracking system which dissipates a fewer amount of electric power.

A semiconductor device has an air-gap/multi-level interconnection structure. The interconnects are insulated from one another by an air gap in the same layer, and by an interlevel dielectric film between layers and from a semiconductor substrate. A high-speed semiconductor device is obtained due to a lower parasitic capacitance.

摘要:
An instruction code is stored to an instruction ROM in advance and the instruction ROM outputs an instruction code signal corresponding to an address signal. A program counter sequentially outputs and stores the address signal in synchronization with a clock signal. An instruction register temporarily stores and outputs the instruction code signal in synchronization with the clock signal. A check code generating circuit generates a check code signal every cycle of the clock signal in accordance with a signal outputted of the instruction register and the address signal. Thereafter, a comparator detects an error in operation of the instruction ROM by comparing the check code signal and a check data signal corresponding to the instruction code and its address value.

A homogeneous electro rheological fluid is provided. The fluid comprises a lyotropic liquid crystalline polymer dissolved in a solvent in low concentrations in a manner in which the fluid does not exhibit a liquid crystalline state. According to the homogeneous electro rheological fluid of the present invention, the problem associated with the precipitation of particles can be circumvented. Moreover, the electro rheological fluid can provide a large difference in torque before and after the application of an electric field; therefore, exhibits good electro rheological properties.

A method for transferring ink on a plate onto a material to be printed by a printing method involves the steps of: providing the ink at predetermined positions on the plate, the ink being sensitive to a field to increase its viscosity so as to have a solidified state or a semi-solidified state; applying the field to the ink to maintain configuration of the ink provided at the predetermined positions on the plate; and transferring the ink onto the material to be printed while maintaining the ink in the solidified or semi-solidified state.
