A nonaqueous electrolyte secondary battery comprises a cathode having a cathode active material capable of electrochemically doping/dedoping lithium, an anode having an anode active material capable of electrochemically doping/dedoping lithium and a nonaqueous electrolyte interposed between the cathode and the anode. The nonaqueous electrolyte includes at least one or more kinds of vinylene carbonate, methoxybenzene compounds or antioxidants. The nonaqueous electrolyte secondary battery has a good cyclic characteristic under any environment of low temperature, ambient temperature and high temperature.

In a mobile communication system having a plurality of radio packet channels of different transmission rate with each other between a base station and a mobile station, undesirable interference to adjacent cells of adjacent base stations is decreased. Signal quality of a receive signal at a mobile station is measured, and the better said signal quality is, the higher packet channel is assigned. Thus, although signal quality is poor because of long distance between a base station and a mobile station, no increase of transmission power of a base station is requested. Thus, interference to adjacent cells is decreased. When high rate packet channel is selected, short packet transmission time may be assigned so that amount of data transmission is kept uniform in spite of said signal quality.

An optical communication module having a roughened bottom of a silicon bench for suppressing optical crosstalk. The roughened bottom prevents stray laser beams from reflecting toward a photodiode. The roughened bottom is further covered with a photoabsorbent resin, pigment or adhesive for absorbing the stray laser beams at a bottom. A cladding of a lightwaveguide are narrowed and are painted with a photoabsorbent resin, pigment or adhesive for absorbing horizontally stray beams propagating in the cladding.

First and second IP cores are formed on one chip. Each of the first and second IP cores has metal layers. In the first IP core, an uppermost layer of the metal layers is thick and is a layer on which a core power source line is formed. In the second IP core, a metal layers equal in level to the uppermost layer in the first IP core becomes an intermediate layer. In the second IP core, thin intermediate layers are formed on this intermediate layer. Thin intermediate layers are layers on which signal lines are formed and have a narrow wiring pitch. In the second IP core, a layer on which a power source line is formed is provided on the thin intermediate layers.
摘要:
An optical communications module in which electrical crosstalk is reduced. The term “optical communications module” represents a surface-mounting-type optical tranceiver, transmitter, or receiver module. The optical communications module has a following structure. (a) An Si substrate carries at least one signal-transmitting section comprising an LD, at least one signal-receiving section comprising a PD, or both together with other components. (b) An insulating substrate is bonded to the back face of the Si substrate. (c) A separating groove separates the Si substrate along the or each boundary line between the sections in order to prevent an AC current flowing through the Si substrate. To attain this object, the separating groove is provided from the top surface of the Si substrate to some midpoint of the insulating substrate. This structure reduces the electrical crosstalk between the signal-transmitting section and the signal-receiving section, between the signal-transmitting sections, and between the signal-receiving sections.

An ESD protection circuit comprising a first pad, a second pad, and a clamp circuit. The first pad is used as an external connection terminal to be connected to a semiconductor integrated circuit. The second pad is used as an external connection terminal to be connected to the semiconductor integrated circuit. The clamp circuit is connected between the first pad and the second pad. The ESD protecting circuit further comprises a control circuit. The control circuit controls the clamp circuit, rendering the same conducting or non-conducting.
摘要:
A plasma etching electrode for dry etching devices for production of semiconductor devices. The plasma etching electrode is prevented from contamination with impurities, provides good thermal and electrical conductance and heat resistance at the joint between the electrode plate and pedestal (or supporting ring), and hence improves etching characteristics and silicon wafer yield. The highly heat-resistant plasma etching electrode includes an electrode plate of silicon which is supported by and uniformly joined to a pedestal by an adhesive. The pedestal is made of graphite. The adhesive includes an epoxy resin containing polycarbodiimide resin and carbon powder. A dry etching device including the electrode is also described.
