Title: Aircraft landing system having simplified effective-range-out indicating (ocl) function
Inventor: ARUFURETSUDO AARU ROPEZU
IPC: G08G5/02
Filed: 1990-07-09
Abstract: PURPOSE: To realize flexible landing and guidance using a simple and low cost unit by an arrangement wherein an azimuth guidance beam and an effective range deviation indicating(OCI) beam are radiated by switching one phased array antenna (PAA). CONSTITUTION: The landing system 20 is operated by transmitting a data preamble containing a timing signal for synchronizing the receiver 40 in an aircraft 24 from a data antenna 36. A PAA 26 arranged as an assembly around the axis 30 of a runaway guides the aircraft 24 by sweeping a guide beam 34 around the runaway 22. Furthermore, the PAA 26 produces two OCI sector beams 32 laterally to the runaway 22 in a space region on the outside of sweep range of the beam 34 by operating a high frequency switch 52 and provides a reference signal for determining deviation of the aircraft 24 from the effective range. A sequence of sixteen time slots is possible for generating an OCI signal and one cycle of the beam 34 follows that time slot thus updating the position of the aircraft 24 continuously.

Title: Semiconductor memory device
Inventor: SUZUKI ATSUSHI
IPC: G11C11/41
Filed: 1986-08-01
Abstract: PURPOSE:To clearly demonstrate the validity or invalidity of tag memory data, to prevent an error due to random data and to speed up initialization by adding a V(validity) bit to data in a tag memory. CONSTITUTION:The V bit is added to a data Au in the tag memory 12, and it is assumed that data is valid and invalid according as '1' or '0' of the bit. Data in the memory 12 is read at an address Ad, and a read-out data RD is inputted to a comparator 14. It compares inputs RD and CD. If they are the same, a coincidence output S1 outputted to a NAND gate G. When the data in the memory 12 is read out at the address Ad, the V bit in a V bit part 12a is also read out, and an output S2 is inputted to the gate G. Even if the S1 is at a level H(coincidence output), the S2 comes to a level L with the V bit set to zero. Accordingly an output S3 is not outputted from the gate G, and 'OK' of reading data memory is not specified. Thus an error caused by random data is prevented, and initialization can be sped up by simultaneously clearing the V bits.

Title: Facsimile communication system
Inventor: MATSUSHITA TOMOHARU
IPC: H04N1/00
Filed: 1983-09-29
Abstract: PURPOSE:To secure the reception of a normal picture signal by transmitting a signal not relating to a picture signal in a short time in preceding an MODEM training signal before the picture signal is transmitted and transmitting a substantial pictre signal in preceding the MODEM training signal just after said transmission so as to avoid an unstable time due to the changeover of an echo suppressor. CONSTITUTION:The signal not relating to the picture signal and preceding the MODEM training is transmitted for 2sec so as to make the instability of the line state elapse during this time, and the picture signal preceding the MODEM training is transmitted with the interval of nearly 75ms after that. Since signal flow is unchanged after the unstable line state, the line state is made stable and it is possible to receive a normal picture signal stably and securely. Since the 2 times MODEM training is used with a prescribed time interval to transmit once the picture signal, the instability due to the switching of the echo suppressor is prevented.

When a fault is detected, the CPU7 sets the signal CS at '1' and actuates the pat 11. Then the contents of latches 8 and 9 latching the output of the counter 2 are transmitted, and the output of the counter 2 is written on the memory 6 via the DMA5. The CPU7 reads the output of the counter 2 to check whether or not the counter 2 has a fault.
