摘要:
A method and apparatus for the direct heat treatment of medium- to high-carbon steel rods which provides an increased tensile strength and drawability by subjecting hot-rolled steel rods to controlled cooling with a coolant. Expanded spiral coils of hot-rolled medium- to high-carbon steel rod having an austenitic structure and which is continuously transported in a generally horizontal direction is cooled by passing the spiral coils through a vessel containing a coolant of a gas bubble-water mixed fluid under a strong turbulent action. The coolant fluid contains a uniform dispersion of oxidizing gas bubbles and is maintained at a temperature of not higher than 95.degree. C. Preferably, the coolant is caused to flow in the same direction as the direction of movement of the coil in the vessel. The surface of the rod may be oxidized by allowing it to cool in air before it is immersed in the coolant fluid.

Provided is a group of rare-earth regenerator material particles having an average particle size of 0.01 to 3 mm, wherein the proportion of particles having a ratio of a long diameter to a short diameter of 2 or less is 90% or more by number, and the proportion of particles having a depressed portion having a length of 1/10 to ½ of a circumferential length on a particle surface is 30% or more by number. By forming the depressed portion on the surface of the regenerator material particles, it is possible to increase permeability of an operating medium gas and a contact surface area with the operating medium gas.

The present invention enables connection between a wireless sensor node and a service server while reducing load on the wireless sensor node.The wireless sensor node transmits a router solicitation message to a gateway apparatus; the gateway apparatus analyzes the message to extract the discrete information of a device or service, searches for a service server based on such information and acquires the configuration information necessary for execution of a service application of the wireless sensor node; the gateway apparatus multicasts the received router solicitation message into a link; a router within the link receives the router solicitation message, and multicast a router advertisement message which contains the prefix information of an address, etc. into a link; the gateway apparatus sets the acquired configuration information in the router advertisement message and transfers the resultant message to the wireless sensor node; and the wireless sensor node analyzes the message.

A portable information terminal includes: a position detecting section that detects a position of the portable information terminal; a selecting section that selects a guidance target object for which voice guidance is to be provided, and detects a guidance target direction that is a direction in which the guidance target object exists with respect to a reference direction, on the basis of a direction in which the guidance target object exists with respect to the position of the portable information terminal; a voice synthesis section that generates a synthetic voice so that a guidance voice for the guidance target object selected by the selecting section is heard from the guidance target direction; and a voice output section that outputs the synthetic voice generated by the voice synthesis section.

摘要:
A wireless network is connectable to an authentication server. Each access point in the wireless network includes a supplicant processing unit, an authenticator processing unit, and a function selector. When an access point is detected within communication range, the function selector selects either the supplicant processing unit or the authenticator processing unit. The selected unit operates to carry out or mediate an authentication protocol and establish a secure wireless link, protected by a pairwise encryption key, between the two access points. Because every access point can operate as either an authenticator or a supplicant, it is not necessary to invoke the services of a master authenticator. If an encryption key is compromised, the effect is limited and does not force the entire network to be shut down.

In a continuous casting process for steel, a molten core inside a strand is stalled at a specific point Q in a pass line of the strand to form a cored portion including no molten steel in the strand downstream of the specific point Q, and the cored portion is rolled by a pair of rolls under pressing into a solid strand in the latter half of a strand drawing stroke. The resulting solid strand comprises a skin formed of a chill crystal and the interior formed of a columnar crystal by addition of proper casting temperature. A through continuous casting/rolling process in which the above improved continuous casting process is combined with a subsequent hot rolling process is also disclosed. A drastic increase in the casting efficiency, an improvement in quality, and an equipment capable of freely adjusting a casting thickness can be resulted so that direct coupling between continuous casting and rolling is achieved and near-net-shaping of various steel materials is promoted.

A photoelectric conversion apparatus includes a plurality of one-dimensionally arranged photoelectric conversion elements, a plurality of common electrodes each for commonly connecting at least two of output individual electrodes of the plurality of photoelectric conversion elements, and separating electrodes respectively formed between the plurality of common electrodes so as to maintain potentials at a predetermined level. The number of intersections between the individual and separating electrodes are identical in the individual electrodes.

A method and apparatus for the direct heat treatment of a medium- to high-carbon steel rod in which the formation of martensite is prevented, even if the starting billet contains segregation. A hot-rolled rod is transported on a conveyor in the form of a sequence of non-concentric rings. The rod is then subjected to controlled cooling in a coolant so that the greater part of any austenite in the entire length of the rod is substantially uniformly transformed to a fine pearlite structure. The sequence of non-concentric rings of the rod is next held at a temperature of 450.degree.-630.degree. C. for a period of 60-300 seconds, with the pitch between each ring being made smaller than at the inlet of the conveyor. Accordingly, a pearlite transformation is effected of any residual austenite.
