Abstract: A motorcycle exhaust system includes a catalytic converter (43) disposed within an exhaust passage (37) for discharging exhaust gas (G) from a multi-cylinder combustion engine (E) and operable to purify the exhaust gas (G). An upstream end of the catalytic converter (43) has different regions (S1 and S2) communicated with upstream exhaust passage portions (37a and 37a), respectively, and a downstream end of the catalytic converter (43) is communicated with downstream exhaust passage portions (37b and 37b) in a number equal to or smaller than the number of the upstream exhaust passage portions (37a and 37a). Also, the catalytic converter (43) has a partition wall (43c) extending in a direction of flow of the exhaust gas (G) for allowing the exhaust gas (G) from the upstream exhaust passage portions (37a and 37a) to flow through the catalytic converter (43) without being mixed together.

Abstract: In a vehicle exhaust apparatus constituting an exhaust passage to an exhaust muffler from a plurality of exhaust pipes connected to a multi-cylinder engine, an expansion chamber is formed on the way of the exhaust passage and is connected to an exhaust collector portion. The expansion chamber is formed so as to expand outward from the exhaust collector portion in a substantially arc or chevron shape when viewed from a direction substantially orthogonal to an exhaust gasflow. Preferably, the expansion chamber is formed in a spherical shape and plural branched exhaust pipes are formed on the exhaust gas downstream side of the expansion chamber.

Abstract: In an ejector cycle device having an ejector, an evaporator is arranged in a refrigerant branch passage connected to a refrigerant suction port of the ejector, an opening/closing member for opening and closing a refrigerant passage is disposed to prevent refrigerant from flowing into the evaporator, and a control unit intermittently controls operation of the compressor. In the ejector cycle device, the control unit brings the opening/closing member into a closing state in a time period for which the operation of the compressor is stopped. Accordingly, it can restrict liquid refrigerant from collecting in the evaporator while the compressor is stopped.

The management center is provided with an SNMP manager, each wireless base station is provided with an SNMP agent, and an SNMP protocol is used to set information of subscriber new registration, registration deletion, operation stop, and operation restart in a subscriber management information table for use in communication permission in accordance with SET request in the wireless access system.

Abstract: Respective evaporators are set to a proper value in evaporation temperature and the efficiency in refrigeration cycle is enhanced, resulting in a reduction of energy consumption. A refrigerating unit and a refrigerator comprise a compressor, a condenser, a plurality of evaporators connected in series, a refrigerant flow rate adjustable unit and a refrigerant, thereby constituting a refrigeration cycle. The refrigerant flow rate adjustable unit controls each respective evaporation temperature of the plurality of evaporators. Preferably, the refrigeration unit further comprises a bypass circuit bypassing at least one of the plurality of evaporators and, when needs arise, the refrigerant is channeled through the bypass circuit.

Abstract: An above deck unit for an AIS (automatic identification system) is externally installed on a ship. The above deck unit includes a radio circuit and an associated antenna for transmitting and receiving a message, a position detector and an associated antenna, associated controller and power supply, and a container for storing these elements. An inboard transmission path, e.g., a cable, connects the outdoor unit for the AIS and an AIS display serving as an interface means for the crew. A signal to be transmitted through the inboard transmission path is a processed, for example, an amplified signal, rather than an unprocessed output of a VHF antenna. Therefore, problems of signal loss or degradation along the inboard transmission path are unlikely to occur. Because the unit is incorporated within a single container, it can easily be installed and transferred. With this antenna complex, it is also possible to suppress interference between antennas.

Abstract: Since a pair of units associated with an antenna unit and a base processing unit is separately placed at a various distance with each other, communication signals also attenuate at a various rate. The amplification gain is adjusted at one unit based upon a receiving signal and a predetermined reception sensitivity level until a desirable amplification is achieved. The desirable amplification value is then transmitted to the other unit to be utilized for reciprocal communication at a desired level between the two units.

Abstract: A cleaning method for a video tape recorder (VTR) employs a cleaning liquid. The cleaning liquid is applied to a tape surface of a tape-shaped support. The tape surface then slides against a surface of a VTR component, such as a magnetic head surface, to clean the surface. The cleaning liquid is a mixture of perfluorocarbons having a boiling point of about 56.degree. C. to about 155.degree. C. The cleaning liquid may also contain a hydrocarbon based solvent and a fluorine based resin. The cleaning liquid acts to clean and to prevent redeposition of contaminants on the surface of VTR component.
