摘要:
A radio communication system minimizes power consumption against noises. The system includes a first radio terminal (10A) with a first transmitter (40A) for transmitting a first data indicative of a specific event, and a second radio terminal (40A) with a battery (14B) and a receiver (20B). The first radio terminal (10A) includes a first bit interpolator (32A) which inserts a check bit pattern of “01010101” at a predetermined cycle into one frame of the first data. The second radio terminal (10B) has a second power controller (60B) which intermittently activates the second receiver (20B) at predetermined intervals in order to receive the bit-interpolated data from the first transmitter. A check bit detector (24B) is included in the second radio terminal (10B) to detect the check bit pattern from within the bit interpolated data and to issue a stop signal immediately upon occurrence of that the check bit pattern fails to appear at said predetermined cycle within a predetermined time frame shorter than one frame length of the first data. In response to the stop signal, the power controller of the second radio terminal terminates a current receiving operation.
摘要:
A power saving wireless fire alarm system has a master station and a plurality of battery-powered fire detecting terminals linked for wireless communication with each other. Upon detection of a fire occurrence at one of the fire detecting terminals, the fire detecting terminal transmit a fire detection message to a master station which in turn transmit a wake-up message to the other fire detecting terminals and thereafter a fire information message which starts a multiple synchronous communication between the master station and the fire detecting terminals. Each fire detecting terminal has a power controller which selects an intermittent reception mode of activating its own receiver only intermittently until receiving the wake-up message or information indicative of the fire occurrence, and select a constant operation mode thereafter to make the fire detecting terminals be ready for the multiple synchronous communication commenced by the fire information message from the master station.

A printing machine (100) according to the present invention includes a rotatable pattern roll (12) and a rotatable transfer roll (14) configured to transfer ink (K) transferred from the pattern roll (12) to a to-be-printed object (S). The transfer roll (14) moves while rotating. For example, the transfer roll (14) moves in any period of time before the ink (K) is transferred from the transfer roll (14) to the to-be-printed object (S), after the ink (K) is transferred from the transfer roll (14) to the to-be-printed object (S), and when the ink (K) is in contact with both the transfer roll (14) and the to-be-printed object (S).
摘要:
A method for manufacturing a magnetic sensor that decreases area resistance and decreases MR ratio of the sensor by eliminating any oxide formation in the capping layer of the sensor. The method includes forming a sensor stack having a multi-layer capping structure formed there-over. The multi-layer capping structure can include first, second, third and fourth layers. The second layer is constructed of a material that is not easily oxidized and which is different from the first layer. The sensor can be formed using a mask that includes a carbon hard mask. After the sensor stack has been formed by ion milling, the hard mask can be removed by reactive ion etching. Then, a cleaning process is performed to remove the second, third and fourth layers of the capping layer structure using an end point detection method such as secondary ion mass spectrometry to detect the presence of the second layer.

In one embodiment, a magnetic head includes a magnetoresistive free layer, wherein a width of the free layer nearest an air bearing surface (ABS) is less than a width of the free layer at a point away from the ABS in a track width direction, with the magnetic head being configured to pass a sense current in a direction perpendicular to a plane of deposition of the free layer. In another embodiment, a method includes forming a magnetoresistive film above a shield, forming a masking layer above the magnetoresistive film, patterning the masking layer such that it exposes portions of the magnetoresistive film, wherein the masking layer defines an area which is narrow near an area that forms an ABS side of a free layer and wider at an area away from the ABS, and removing the exposed portions of the magnetoresistive film to form the free layer.

A process for producing a food is disclosed. The food material is contacted with a degradative enzyme and any one or more of a thickener in a non-solvated state, microorganism which generates a viscous material, nutritious substance and seasoning according to need. Then, a pressure treatment is performed followed by cooking after softening the food material by the action of the degradative enzyme. The process may be carried out in a packaging material for vacuum packaging such that the food retains the shape, color, taste, and flavor of the food material and includes the degradative enzyme inside the vacuum packaging uniformly.

An air intake passage system includes an external air intake port provided in a rear portion of a top cover and a passageway section projecting upwardly from the engine cover for directing taken-in external air to the engine. The top cover is provided over the engine cover with a gap therebetween such that the taken-in external air is allowed to flow into the passageway section and a water discharge section is provided between the engine cover and the top cover. Water, having entered together with external air, flows along the upper surface of the engine cover, bypasses the passageway section and is then discharged via the water discharge section.
