Title: Medium processor
Inventor: WAKI HISAO
IPC: G11B19/02
Filed: 1990-06-21
Abstract: PURPOSE:To shorten the processing time of a whole device by reading the magnetic strip of a medium before executing the putting-aside operation of the medium, and omitting the operation of a putting-aside mechanism if data is normally read. CONSTITUTION:At the time when the medium moves to a position A for executing the putting-aside operation, the data on the magnetic stripe 26a is read by using the movement of the medium. At that time, if the data of the magnetic stripe 26a could be normally read, it is decided that the medium 26 with the magnetic stripe is carried in without moving obliquely, and the operation is shifted to the next operation without executing the putting-aside operation. On the other hand, in case that the data on the magnetic stripe 26a could not be normally read, it is decided that the medium 26 with the magnetic stripe moved obliquely or the deviation of a reading position is large, and the putting- aside operation is executed at the position A. Thus, medium processing can be speeded up.

Title: Frequency control system for very small satellite communication system
Inventor: TANIGUCHI TAICHI
IPC: H04B7/204
Filed: 1989-06-23
Abstract: PURPOSE:To economize an equipment and to improve the utilization efficiency of a line by adopting a variable frequency oscillator for a frequency oscillator of a very small satellite(VSAT) earth station and following the control from a central station. CONSTITUTION:A very small satellite earth station(VSAT station) is provided with a demodulator 3, a modulator 4 and a variable frequency oscillator 5, and the demodulator 3 extracts DELTAf information for its own station among reception data resulting from demodulating a reception IF signal. Then the oscillator 5 corrects the oscillated frequency of a carrier variable frequency oscillator by DELTAf and sends the result via the modulator 4. In this case, not the frequency fixed oscillator but the frequency variable oscillator such as a voltage controlled crystal oscillator is used for the carrier variable frequency oscillator. Thus, the variable oscillator is employed for the frequency oscillator of the VSAT station to follow the control from a central station(HUB station) in such a manner, thus an expensive highly stable frequency oscillator is not required to economize the equipment and to improve the line utilization efficiency.
