An air blowing device includes a housing with a suction port and a blow-off port, and a fan placed in the housing. The fan includes a fan case with a tongue section, an impeller, and a motor. The fan case includes an inlet and an outlet, and is shaped such that a space between the impeller and an inner wall of the fan case increases along a rotary direction of the impeller up to a cross section cut along a line between the tongue section and its opposite section. An opening area of the fan case at the tongue section is kept equal or decreases up to the outlet.

To reduce power consumption for communication operation wherein a client terminal at the time of offline searches a base station or access point.A server uses a communication information predicting algorithm to predict a location or time whereby the server becomes an offline state over a movement route of a client terminal, and a location or time whereby the server returns to an online state, and informs to the client terminal. The client terminal suspends a communication function when reaching the informed offline predicted location or time. The client terminal at the time of offline determines that the current location or time has reached an online return predicted location or time using location recognition or point-in-time recognition, and restores the communication function.

When transmitting position/time information calculated by means of a GPS function to a server apparatus, authentication is carried out with the server apparatus. The position/time information may be certified as legitimate measured by a portable apparatus with a GPS reception function employed by a user. When transmitting information related to the position and the time acquired from a portable phone terminal having the GPS function and a network function by means of the GPS function to the server apparatus, authentication is carried out between the portable phone terminal and the server apparatus. The position/time information is transmitted to the server apparatus, only if the server apparatus is authenticated as a legitimate counterpart for connection. A secret key holding section is provided for holding different secret keys for different apparatuses. The position/time information measured based on an electromagnetic wave received from a positioning satellite is digitally signed by means of the secret key. The identification information and the position/time information having the digital signature are then transmitted to a counterpart.

Skin material of a clad material is composed of one or more layers, each layer of the skin materials is made of a metal different from the core material in their component compositions, and at least one layer of the skin material has a cast microstructure, when the skin material is superposed on either of one or both faces of the core material.
摘要:
A method for manufacturing a clad material composed of a core material and one or more skin materials which are superposed on either one or both faces of the core material, includes a clad material preparation process where an ingot for core material is manufactured by dissolving and casting a metal, and an ingot for skin material is manufactured by dissolving and casting a different metal for skin material, without hot rolling. The ingot for skin material is superposed as a skin material at a predetermined position of either one or both faces of the ingot for core material and the superposed material is hot-rolled to manufacture a clad material.

摘要:
Equipment for manufacturing skin material of a clad material includes a casting apparatus which melts and mixes a metal for the skin material different from the core material in their component compositions, and casts the skin material; an ingot-cutting apparatus which cuts an ingot for skin material which is cast by the casting apparatus; and a conveying apparatus which conveys the ingot for skin material among each apparatus. The ingot-cutting apparatus is a slicing apparatus which slices the ingot for skin material into a predetermined thickness.

In an AC-input type brushless DC motor, a current control circuit controls an average current of an inverter circuit, a current indication circuit makes addition or subtraction, with respect to a reference current value, to the average current to be supplied to the inverter circuit such that the average current falls into a correlation indicated by a correlation indication circuit. The foregoing structure allows setting speed-torque characteristics of the brushless DC motor such that the torque increases at a higher rpm of the motor. The characteristics are good for driving a fan.

Memory corruption can be suppressed. When data stored in a random access area are read, the read data (physical block) are retrieved by a logic block number and newest data are read by referring to an incremental counter of data having that logic block number. When data are stored in the random access area, the incremental counter and the logic block number of data already stored in the random access area are referred and a physical block set to be unnecessary is set to a writer buffer, and then the data are written to this write buffer.
