Title: Operation supervisory unit
Inventor: TSUCHIDA YOSHIYUKI
IPC: G05B9/02
Filed: 1978-09-26
Abstract: PURPOSE:To realize a safe and assured plant operation by giving decision whether the operation of the operation switch is carried out by the operator based on the correct selection and then informing the result of the decision to the operator. CONSTITUTION:With the clockwise or counterclockwise turn of control switch 1, operation signals S1 and S2 are transmitted to input control unit 2. Furthermore, signal S10 is sent to central arithmetic unit 3 along with signal S20 sent to controlled unit 8 via decision unit 7 each. With transmission of S10 to unit 3, signal S10 is collated to the signal which gives a collation to the correctness of selection as well as the contents of the operation signal set previously. Thus a decision is given to the operation contents of switch 1 about its inhibition or not, and then signal S3 or S4 is sent to unit 7. Unit 7 inhibits transmission of signal S20 to unit 8 in the case of the inhibition signal, thus displaying the malfunction through display unit 1B.

Title: Weak radio wave radio communicating method
Inventor: WATARI TATSU
IPC: H04B5/00
Filed: 1987-05-15
Abstract: PURPOSE:To prevent other radio systems and instruments from being disturbed by arranging a 2nd antenna so that a 1st antenna is given a combination of feed conditions and directivity which cancels an electromagnetic field generate at a remote place. CONSTITUTION:The 1st antenna 3 is arranged at a nearby interval while having signal coupling characteristics close to an open transmission line and the 2nd antenna 6 is so arranged as to give the 1st antenna 3 the combination of feed conditions and directivity which cancels an electromagnetic field produced at a remote place. Then a radio signal is transmitted forth and back between the open transmission line and 1st and 2nd antennas 3 and 6. There, the radio wave signal can be reduced by making opposite-phase radio waves from both antennas cancel each other at the remote place without any influence upon the coupling between the open transmission line and a normal coupling antenna. Consequently, disturbance to other radio systems and measurement system which handle an extremely low level.

Title: Stabilization of diazonium salt
Inventor: MIYAKAI TAKUSHI
IPC: C07C245/20
Filed: 1983-06-30
Abstract: PURPOSE:To carry out the storage of a diazonium salt stably for a long period, by contacting the diazonium salt with a polymer containing sulfonic acid group and more than specific amount of a specific structural unit. CONSTITUTION:A diazonium salt (e.g. 2,5-dimethoxybenzenediazonium) can be stabilized by contacting the salt with a polymer containing sulfonic acid group and >=10mol% of the recurring unit of formula (R<1> and R<2> are H or methyl; R<3> is 1-18C alkyl, 6-10C aryl, etc.). Since diazonium salt is liable to be decomposed easily with heat as well as light, it must be stored in dark place at a low temperature. The light and heat stabilities of the diazonium salt can be improved by storing the salt as a mixture with the above polymer.

IPC: H02H3/05
Filed: 1990-05-10
Abstract: PURPOSE:To obtain an inspection circuit, which can be built in a power supply and can operates with low power dissipation and low heat production to improve workability, by connecting any one of an open load or a short circuit load selectively between output terminals of a protective circuit through a selection switch. CONSTITUTION:An inspection circuit 21 comprises an open load 22 and a short circuit load 23, any one of which is connected selectively between the output terminals of a power supply 11 through a switch 24. When a protective circuit 13 is set with a constant voltage or an overvoltage, switching is made selectively to the open load 22 through the switch 24. At this time, current scarcely flows and power is not dissipated. When the protective circuit 13 is set with a constant current or an overcurrent, switching is made selectively to the short circuit load 23 through the switch 24. At this time, voltage is scarcely produced and power is not dissipated. Consequently, the inspection circuit 21 functions with quite low power.

Title: Control system of received carrier detecting circuit
Inventor: HOSOKAWA TSUTOMU
IPC: H04B3/06
Filed: 1979-09-18
Abstract: PURPOSE:To make it possible to perform operation based upon the advice of  CCITT without reference to the time when a received carrier is being cut off by detecting whether a synchronizing signal has been received from a received waveform and then by controlling a received carrier detecting circuit according to the degree of the convergence of an automatic automatic equalizer in case of instataneous breaking. CONSTITUTION:Input signal A is applied to reception level deciding circuit 1 having hysteresis characteristics and synchronizing signal detecting circuit 3. When input signal A is at a low level and deciding circuit 1 is OFF, its output is supplied to timer 2 and after its time limit, the received-carrier detecting circuit is turned off. As deciding circuit 1 turns on, detecting circuit 3 is enabled to detect a synchronizing signal. The output of detecting circuit 3 is led to the control input terminal of selector 4 and when the synchronizing signal is received, deciding circuit 5 turns on before user's data are outputted to make sure of synchronism with the reception part. Once the received carrier is instantaneously cut off, signal quality detecting circuit 6 outputs a high-level signal and RSFF7 is set, so that its output B will be turned on.
