An electric power distribution member for stator is a member for connecting a plurality of coils to one another, each having coil opposing end portions located on an inner circumferential side and on an outer circumferential side in a radial direction of a stator, and it includes a plurality of conductor pieces and a plurality of insulating holding portions. The conductor piece has a first connection end portion in a flat plate shape connected to an inner circumferential side end portion of a coil and a second connection end portion in a flat plate shape connected to an outer circumferential side end portion of another coil. In addition, the insulating holding portion integrally holds adjacent conductor pieces at a distance from each other at a portion other than the opposing connection end portions of each conductor piece. The insulating holding portions are arranged in a manner discrete from one another.

An electric potential of an epitaxial layer 2A provided under a bonding pad 5 to which a resonance circuit for a VCO is to be connected is fixed to a predetermined (Vcc) electric potential through a resistor 6 in a conventional floating state. Consequently, a speed of a change in the electric potential of the epitaxial layer 2A is increased and a value of a parasitic capacity is stabilized quickly. Consequently, a drift can be improved when a power supply is turned ON.

A pair of electronic devices connected through a communication cable serve as a sending device and a receiving device, respectively. The electronic device on the sending device includes a generator for generating a control signal. The control signal operates to turn on a power supply of the electronic device on the receiving side when the power supply of the electronic device on the sending side is turned on or to turn off the electronic device on the receiving side when the electronic device on the sending side is turned off. The control unit is included in the electronic device on the receiving side. In response to the control signal given from the generator, the control unit operates the power supply of the electronic device on the receiving side.

A biological purifier of the present invention includes chaff retaining sulfate-reducing bacteria. A biological purification system of the present invention includes a treatment container in which anaerobic conditions are maintained, and the above biological purifier is stored; a supply system for supplying the untreated waste water into the treatment container; and an discharge system for discharging treated water from which the heavy metal ions have been removed in the treatment container by the purifier, from the treatment container. In a biological purification method of the present invention, the biological purifier and the untreated waste water are brought into contact with each other under anaerobic conditions, thereby precipitating and removing the heavy metal ions as sulfide from the untreated waste water.

In an electronic translator apparatus, synonymous phrases (title data) and sentences in plural languages are stored in correspondence to each other. These phrases or sentences are read out and translated. This electronic translator apparatus stores the title data as a basic phrase and the explanatory data relating to the title data, thereby allowing a wide range of translation. The title data can be translated into plural languages which are displayed simultaneously. The title data and corresponding sentences are separately stored, thereby increasing the number of sentences that can be translated. The display method is varied depending on the necessity. If the sentence to be translated is long, part of the original sentence during displaying is ommitted and the translated sentence is displayed in whole. When translating into English, an article may be added or a plural form may be expressed so as to translate properly. When translating into Korean, accurate translation corresponding to the presence or absence of PACHIM may be realized.
摘要:
A catalyst ink for improving the performance of catalyst electrodes in a fuel cell is produced by the following procedure. A catalyst dispersion is prepared by dispersing catalyst-supported particles as conductive particles with a catalyst supported thereon in a solvent. A gel material having viscoelasticity is prepared by mixing an ionomer with a volatile solvent. A catalyst ink having a desired viscosity is produced by stirring and mixing the catalyst dispersion with the gel material.

Disclosed is a fuel cell wherein deterioration of fuel cell performance due to dry up phenomenon and flooding phenomenon is suppressed. Specifically disclosed is an assembly for fuel cells or a fuel cell wherein a catalyst layer contains a first composite catalyst particle containing a catalyst supporting particle and a solid polymer electrolyte and a second composite catalyst particle having a larger volume average particle diameter than the first composite catalyst particle and arrangement of the first composite catalyst particle and the second composite catalyst particle is controlled in the thickness direction of the catalyst layer. Consequently, deterioration of fuel cell performance due to dry up phenomenon or flooding phenomenon can be suppressed, thereby realizing a fuel cell with high efficiency.
