Abstract: A fixture for slider lapping includes a holding portion for holding the object with its surface to be lapped toward the lapping surface of the lapping device; a main body for mounting the lapping fixture to the lapping device; a plurality of load-applied portions which are arranged along said longitudinal direction and independent from said main body, said load-applied portions receiving a load which presses the surface to be lapped to the lapping surface tightly from at least the lapping device; a plurality of connection members connecting said holding portion and said main body along said longitudinal direction at intervals; and a plurality of wrist portions connecting said connection members and said holding portion; wherein at least one wrist portion is disposed between said adjacent connection members; at least one wrist portion is disposed at each outer side of the connection members which are located at both ends of the longitudinal direction.

Abstract: The present invention relates to a mobile communication system in which data is transmitted and received through a wireless transmission line between a mobile station device and a network-side device. A receiving-side device includes a retransmission request transmitter configured to transmit, to a transmitting-side device, a retransmission request for requesting retransmission processing on each data unit of the data, when a reception error is detected in the data unit. The transmitting-side device includes a retransmission time storage configured to store a retransmission time at which the retransmission processing is performed on the data unit; and a retransmission controller configured to control so as not to perform the retransmission processing on the data unit related to a received retransmission request, when the retransmission time of the data unit is stored and a difference between the retransmission time and a current time is shorter than a retransmission prohibition period.

Abstract: Piezo oscillators having a quick start-up circuit, which applies a start-up quickening voltage to the piezo resonator only for a predetermined length of time after the application of power supply voltage, added to a piezo oscillating circuit. The start-up time taken for the piezo oscillators to reach the steady-estate oscillation from the non-oscillating state can be significantly shortened. The phase noise characteristics and frequency stability characteristics are not affected, since the start-up quickening voltage is removed after the predetermined length of time.
