Title: Random over-sampling transmission method
Inventor: KANEKO SHIGEKI
IPC: H04J3/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To eliminate the delay of transmission that is caused by the staff multiplexing and to improve the degree of freedom to the transmission rate of an input signal by sampling a signal with the time division multiplex frequency, transmitting the sampled signal to a time division transmission channel, composing the divided PCM signals into a continuous stream, converting the continuous stream into an analog wave to form a waveform and outputting serially the signal converted into the PCM signals. SOLUTION: The signal that is outputted from a PCM random over-sampling(ROS) part 20 is sampled by a sampling part 23 with the transmission frequency of a time division multiplex clock 22 or 1/n transmission frequency and then multiplexed. This multiplexed signal is transmitted on the transmission channel of a transmission line 25. Then the signal is divided by a dividing part 26 and outputted to every transmission channel. These divided signals are combined with the data on each transmission channel and composed into a continuous stream by a multiplexed frame composing part 27. The PCM signals of the continuous stream are once converted into the analog waves by a stream forming part 30 and the waveforms of the analog waves are shaped. Then the output signals 1 and 2 which are converted into the PCM signals are serially outputted.

Title: Space diversity receiving system
Inventor: KINOSHITA KAZUOKI
IPC: H04B7/08
Filed: 1984-02-24
Abstract: PURPOSE:To perform switching of an SD (space diversity) circuit with no hit and also to eliminate the effect to other circuits, by performing switching between the main and secondary antennas for SD circuit while a burst signal is switched to another burst signal for a slave station using said SD circuit. CONSTITUTION:A burst signal is supplied to main and secondary antennas 7 and 8 from a slave station A through an SD circuit. An antenna switch circuit 11 usually selects the antenna 7. While the burst signal supplied from a slave station B through an antenna 9 is synthesized by a hybrid circuit 2 and set within a frame. Then this signal is demodulated by a receiver 13, and the original base band signal is extracted through a terminal 10. Here if the SD circuit has a fading fault and the errors of the base band signal are increased, a switch drive circuit 12 is actuated. At the same time, the circuit 11 is actuated between a burst signal given from the station A and the next burst signal. Thus the antenna 7 is switched to the antenna 8. The circuit 11 consists of a diode and ferrite and has an extremely short working time to switch the SD circuit with no hit.

Filed: 1983-03-03
Abstract: PURPOSE:To prevent surely to compress liquid upon starting by a method wherein a time when the compressor arrives at the revolving number capable of discharging all of staying liquid in the compressor to the outside thereof is determined in accodance with the rotating speed of a driving source. CONSTITUTION:When a switch 8 is put ON, a wave form generating circuit 20 generates and outputs a square wave with a predetermined time interval. On the other hand, a time determining device 10 outputs after a discharge finishing time T determined in accordance with the rotation speed of the driving source. Here, the time T is a comparatively early time in case the rotating speed of the driving source 9 is high while the time T is comparatively late time in case the rotating speed of the same is low. Thus, an exciting current control, restricting the revolving speed of the compressor 6 into a speed low than the liquid compressing speed, may be effected without any excess and shortage by a method wherein the discharge finishing time T is determined in accordance with the rotating speed of the driving source 9.

Title: Entrance device for elevator cage
Inventor: MURATA KAZUMASA
IPC: B66B13/28
Filed: 1978-03-27
Abstract: PURPOSE: To safely move a wheeld chair into or out of an elevator cage without shock by providing an auxiliary sill steadily displacing to the same position as the surface of the sill of the cage to thereby reduce the gap between the sills between the cage and the hall.  
     CONSTITUTION: A detector 15 is urged by a transfer unit 13 to detect the auxiliary sill 14 at the retarded position. When a sliding door 2 is opened, a rod 8 is lifted via a link and a lever by the operation of an opening and closing mechanism 5. Thus, the transfer unit 13 is rotated counterclockwise via a pushing element 11. The excessive lift of the rod 8 is absorbed by the deflection of the element 11 at this time to exactly displace the transfer unit 13. Thus, the sill 14 is lifted and the sill 3 is extended to make contact with the oblique surface 16 and to allow the upper surface of the sill 14 to coincide with the surface of the sill 3. Thus, the gap A is reduced to become gap B.
