Conventionally, high-level communication using the message cannot be achieved. The high-level communication using the message can be achieved by a message transmission device including a component candidate group storage unit capable of storing one or more component candidate groups including two or more groups of component candidates forming a content, an input reception unit configured to receive an input for constituting a content including one or more components determined by the selection of one component candidate from two or more component candidates included in one component candidate group, a content constitution unit configured to constitute the content by using the selected one or more components according to the input, and a message transmission unit configured to transmit a message including the content.

A method of the invention for performing burn-in test includes assembling, on a fixture stand, a plurality of light source elements and a plurality of light detectors for monitoring a light output from a corresponding one of the plurality of light source elements; and electrifying the plurality of light source elements in a state where at least the plurality of light source elements and the plurality of light detectors are immersed in an insulation liquid. Thereby, it is realized to hold a stable temperature in a short period of time, to maintain a temperature that does not deviate from normal load conditions, and to perform a sorting test between defect parts and good part for light source unit chips without causing damage to the elements.

摘要:
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.

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.
