  • Publication number: 20120160093
    Abstract: An air cylinder having a simple and effective configuration to reduce the axial length and provide ease of processing. A sliding bearing that guides a piston rod is disposed at a position adjacent to a groove in which a rod packing is fitted. One end of the sliding bearing serves as the side wall of the groove and prevents displacement of the rod packing. The other end of the sliding bearing extends so as to cover part of a yenta of a first port. An orifice having a sectional area smaller than that of the yenta is formed at the position of the yenta by the sliding bearing.

  • Patent number: 8199854
    Abstract: An encoder encodes sound data and the like to generate a binary signal. A mapper converts the binary signal into a four-level symbol and outputs the four-level symbol. A base band filter includes a root raised cosine filter and a sinc filter. The base band filter blocks a predetermined frequency component of a symbol to shape the symbol into a waveform signal and outputs the waveform signal shaped. An FM modulator transmits a signal subjected to FM modulation according to a magnitude of an amplitude of a waveform signal to a receiving unit. When a symbol of ±3 is outputted from the mapper, a frequency shift of a signal transmitted from the FM modulator has a predetermined value in a range of ±0.822[kHz] to ±0.952[kHz]. This makes it possible to provide a modulating apparatus, a mobile communication system, a modulating method, and a communication method that use a modulating method that can conform to the FCC rule to be enforced in 2005 without using a linear power amplifier.

  • Patent number: 7826403
    Abstract: When no messages exist which must be notified to a mobile transmitting/receiving apparatus (102), a carrier signal of non-modulation is outputted in an area of control information of transport data having a frame structure. As a specific example, an FSK modulator (16) causes a carrier signal of non-modulation to be outputted by a transmitting circuit (17) from a line control apparatus (101) in correspondence with the area for control information in which non-modulation data is set by a frame data processing unit (15), while causing a modulated wave signal as four-level FSK modulated to be outputted in the areas other than the non-modulation data area. When non-modulation data is set in the area for control information, function channel identification information in the same frame is set as non-modulation identification data, thereby allowing any unstable operation in the mobile transmitting/receiving apparatus (102) on the receiving side to be avoided.

  • Patent number: 7805294
    Abstract: When a sound presence/absence detector (12) detects a sound absence interval, a non-modulated carrier signal is outputted in an area used to transmit speech data that are included in transmission data having a frame structure and that correspond to the sound absence interval. That is, an FSK modulator (14) causes a transmitting circuit (15) to output the non-modulated carrier signal from a wireless communication apparatus (100) in the area used to transmit the speech data corresponding to the sound absence interval. In the meantime, a four-level FSK modulated wave signal is outputted in the areas other than the one of the sound absence interval. A non-modulation discriminating data for allowing the sound absence interval to be determined are included in an area of channel identifying information included in the transmission data having the frame structure, and allow a communication terminal apparatus at the receiving end to avoid any unstable operations.

  • Patent number: 7738436
    Abstract: Information, which has a frame structure and is to be transmitted from a line control apparatus (101) through a control channel to a mobile transmitting/receiving apparatus (102), includes function channel identifying information indicative of the type of information transmitted in an area of control information. When no message is existent which must be notified to the mobile transmitting/receiving apparatus (102), the line control apparatus (101) establishes an idle message in the area of control information and also establishes the function channel identifying information, which is in the same frame, as idle identifying information. If the function channel identifying information is the idle identifying information, the mobile transmitting/receiving apparatus (102) switches a receiving operation in the area of control information into a reception stop operation. Otherwise, the mobile transmitting/receiving apparatus (102) continues the receiving operation in the area of control information.
