Title: Radio data communication equipment and radio data communication method
Inventor: TAKAHASHI NOBORU
IPC: H04L1/00
Filed: 1993-01-14
Abstract: PURPOSE:To improve the transmission efficiency of a radio channel with bad quality by sending succeeding data whose length is halved upon the receipt of information having an error and whose length is doubled when no error is in existence in the data. CONSTITUTION:A buffer 11 of a data transmission control section 1 stores tentatively data to be sent and a transmission section 12 sends data in the unit of specific message length. Furthermore, upon the receipt of a data NG signal representing a faulty reception status and information representing error data from an error check section 3, a processing section 13' divides a message of erroneous data into two and gives a status to each divided message and sends the resulting data to a transmission section 12, and upon the receipt of a data OK signal representing a normal reception status in the received status from the error check section 3, the processing section 13' restores the length of the message to the length of message before the division and sends the data of the restored length. Thus, when the quality of a radio channel is bad, the message length is decreased to reduce an error occurrence rate and the message length is increased when the quality is recovered to send data.

Abstract: PURPOSE:To execute the reproduction from the reproducing direction before an eject at the time of repeated slot-in by providing a memory plate having a pressing part for releasing the detainment of a head plate and an abutting part which can about on the head plate. CONSTITUTION:When a head plate 16 advances, a memory plate 11 pushes a projecting piece 13a of a lock arm 13 by a pressing part 11a, and the lock arm 13 is rotated clockwise. Therefore, the head plate 16 is not locked but moved back-ward by elastic force of a spring 15.

Subsequently, when the head plate 16 is advanced again by the power plate 14, the power plate 14 is locked to a lock arm 13 by a detaining part 14a and becomes a play state. In such a way, by executing the advance/retreat operation of the head plate 16 two times extending from the eject to the play mode, the tape can be started from the same direction at the time of restarting it after the eject.

IPC: H05B6/68
Filed: 1979-02-23
Abstract: PURPOSE: To eliminate some uneven heating of the heated item by a method wherein a mean temperature at the side of the heated item may be sensed.  
     CONSTITUTION: The heated item 3 in the heating chamber 1 is placed on a pan 4 which is rotated by a driving motor 5 and the item is heated by a high frequency energy oscillated from the magnetron 2. Then, an infrared ray sensing window 6 is provided at a side wall surface 1' of the heating chamber 1. The infrared ray sensor 7 outside of the heating chamber 1 detects or senses the infrared ray produced from the heated item. In this case, a horizontal light axis 9 of the sensor 7 is directed to a rotary center 10 of the rotary pan 4. Since a side surface of the heated item 3 is appeared at the light axis 9 of the sensor 7 at the all circumferences while being rotated, so even if the uneven heating is produced, it is possible to get an integration value or a mean value of the infrared ray during a time that the pan 4 rotates by  one turn. It is possible to detect such a temperature as being approximate to an  entire mean temperature of the heated item 3.
