Abstract: PURPOSE:To prevent the influence of diffused external light by modulating different frequencies having data independently of each other and transmitting them as optical signals ad receiving them to demodulate them independently of each other and removing an error data signal to obtain the other data signals. CONSTITUTION:The data signal supplied to an input terminal 10 is modulated by carrier frequencies f1 and F2 different from each other and converted to an optical signal through a driving circuit 16 by a light emitting diode 17 and sent to atmosphere. The received optical signal is converted to an electric signal and is supplied to a comparator 24. The comparator 24 detects that the level of the frequency f1 is higher, and a switch circuit 25 is changed over to the side of a contact (1) to send the output signal having the frequency F1 to a demodulating circuit 26, and it is demodulated to a digital signal and is stored in a memory circuit 28. When the succeeding frequency f2 is received, it is stored in the same manner. Data signals corresponding to these stored frequencies f1 and f2 have error detected by a CRC checking circuit 30 to remove an error data signal, and the other data signals are sent to an output terminal 31.

Filed: 1986-03-19
Abstract: PURPOSE:To obtain a charge transfer device having a high transfer efficiency even in high-speed transfer of a large loading, by dividing a transfer electrode into a plurality of transfer electrode groups. CONSTITUTION:A transfer channel is divided into groups of transfer electrodes 10-13. Pulse driving circuits 15-18 generate pulses which are steep both in the rise phase and the decay phase as shown by the graph 60. These pulses are applied to the transfer electrode groups 10-13.

Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To facilitate variable speed data transmission and asymmetrical data transmission. SOLUTION: A TDMA(time division multiple access) frame has N time slots 11 for up lines and M time slots 12 for down lines. A radio base station allocates a time slot to each radio terminal station by a control channel(C ch). In such a case, allocation is successively performed in order of a time slot in the neighborhood of the center of the time slot 11 and 12 for the up and down lines. Thus, mutual intervals between allocated time slots become relatively equal and are effective to the variable speed data transmission and the asymmetrical data transmission.

Title: Forming method of axis-symmetrical parts
Inventor: OOMORI SHIYUNJI
IPC: B21J5/02
Filed: 1979-05-25
Abstract: PURPOSE: To hermetically forge the axis-symmetrical parts of less excess metal without producing any shrinkage by slidably fitting outer punches and inner punches to upper and lower dies and moving these synchronously or independently.  
     CONSTITUTION: Outer punches 4", 6" are slidably fitted to upper and lower dies 2', 3' and inner punches 5", 7", are mutually slidably fitted to the outer punches 4", 6". When the blank is pressed in the state that the inner punches 5", 7" are held protruded from the outer punches 4", 6", it deforms until part of the ends 8 of the laterally extruded parts contact the dies 2', 3'. In this case, the blank flow is in the lateral direction only and defects such as shrinkage do not occur. Thence when the pressing force of the outer punches 4", 6" is weakened and the inner punches 5", 7" are further pushed in, the blank flows to the lateral ends 8 and outer punch corner parts 9. At this time, the outer punches 4", 6" are pushed back in the opposite direction and retreat while they are giving back pressure to the blank. As a result of this, the flow of the blank becomes smooth. When this state progresses, the thickness between the punches becomes small and the forming is completed.
