Title: Spread spectrum equipment
Inventor: OKITA SHIGERU
IPC: H04B1/7073
Filed: 1990-05-15
Abstract: PURPOSE:To devise the equipment such that a false frame synchronizing code hardly takes place and malfunction of a receiver is prevented by employing an initializing period of scramble in the unit of M (M is an integer) frames at the sender side. CONSTITUTION:A voice data is fed to an input terminal 21 of a spread spectrum section and given to a scramble section 22.

Title: Output device for ddc system
Inventor: HASEGAWA MASAKAZU
IPC: G05B15/02
Filed: 1986-05-26
Abstract: PURPOSE:To control the process value with high accuracy and also to reduce the disturbance in the process value even at the time of CPU trouble, by securing the linear changes in the frequencies of output pulse and control command of a CPU and at the same time to maintain the present state of a control part at the time when the CPU has a trouble. CONSTITUTION:The control command given from a CPU is supplied to the D input of a preset counter 17 and the initial value of this counter is set. At the same time, the control command of the CPU is also written to a buffer register 8 and therefore a pulse generator 18 produces a pulse of a frequency proportional to said control command. When the output of the generator 18 is supplied to the clock input T of the counter 17, the counter 17 starts a count- down operation from its initial value. When the count value of the counter 17 is equal to zero, the output of the generator 18 is delivered to a control part via an AND 19 while the borrow output to be changed to L from H is kept at H. Thus the frequency of an output pulse has a rectilinear change to the control command. The present state of the control part is kept as it is by the function of the AND 19 at the time when no control command is delivered any more due to a trouble, etc.

Title: Radio communication equipment
Inventor: OTSUKA SHIGERU
IPC: H04B7/26
Filed: 1985-06-06
Abstract: PURPOSE:To eliminate waste power from being supplied to a radio equipment of a repeater station and a terminal station by applying battery saving according to the signal of a battery saving timing generation circuit provided to each of the relay station and the terminal station when the channel identification synchronizing signal sent from the base station is not detected for a prescribed time or over. CONSTITUTION:A battery saving timing generating section shown in one dashed chain lines in figure is provided to a terminal station and a repeater station. If a host station is faulty and a channel identification synchronizing signal from a base station 51 is not received for a specified time or over while power is given to the radio equipment, the repeater stations 52, 53 and the terminal station 54 use the own battery saving timing signal to apply battery saving. Since the period of the battery saving differs from the period of the battery saving synchronizing signal sent from the base station 51, even when the host station is restored, because the channel identification synchronizing signal is received from the base station 51 without fail, the battery saving is applied when the battery saving synchronizing signal is received.
