Title: Information recording medium and information recording device for it
Inventor: YONEZAWA SEIJI
IPC: G11B7/09
Filed: 1981-06-24
Abstract: PURPOSE:To prevent the deviation between tracking signals even in case of an error in aligning optical systems, by providing an information-recordable blank area between tracking grooves where pulse signals differing in frequency are recorded alternately as the tracking signals. CONSTITUTION:Laser light radiated from a laser light source 1 forms a fine light spot 4 on a disk 3 through a condenser lens 2. On the disk 3, plural pulse signals differing in frequency are recorded concentrically and alternately as projecting and recessed or light and dark track grooves 5, 6 and 7, so the light spot 4 is dirfracted. Then, its diffracted reflected light is passed through a half-mirror 2' and photodetected by a photodetector 9, where it is transduced into an electric signal to compare the output levels of respective frequency components; and deviation from the center of a track 8 on which information is recorded is detected by an error signal, which is used to exercise control so that the light spot 4 is in the center of the blank track 8.

Abstract: PURPOSE:To reduce the size of a port for discriminating transmitted received data and to provide the port with a fixed constitution even if the number of data transmitted/received between microcomputers is different by using a status discrimination signal line and a transmitted data updating discrimination line. CONSTITUTION:When data are to be transmitted from a microcomputer 1a to a microcomputer 2a, a microprocessor MPU3 turns the status discrimination signal line 17 to the ''1'' level through an address decoder 5 and a sent data discriminating port 9a. Then, the MPU3 specifies a data output port 10, writes the sent data in parallel and inverts a signal on the sent data updating discrimination signal 20 to the ''H'' level through a decoder 5 and the port 9a. An MPU4 detects the status of the signal line 17 and the discrimination line 20 and reads the data from the port 10 in parallel through a data input port 12. Thereafter, the updating of the data can be discriminated by inverting the signal on the discrimination line 20 in every updating of the data, so that the discrimination can be executed only by one discrimination line 20. Thus, the discrimination port can be reduced at its size and provided with a fixed constitution.

Title: Protection of overcurrent in fuel-battery generation-system
Inventor: MACHIDA TAKEHIKO
IPC: H02H7/18
Filed: 1979-07-31
Abstract: PURPOSE:To simply prevent overcurrent from reaching a critical level by substituting an inert gas for both/either of reaction gases in a fuel-gas chamber and an oxidizing-agent-gas chamber at the point when a DC overcurrent is detected. CONSTITUTION:If a DC current exceeds the detection level of an overcurrent detector 19, the detector 19 gives cross valves 14 a signal commanding a change-over. Then O2 gas as an oxidizing agent is stopped being supplied, and N2 gas which is an inert gas is sent into an oxidizing-agent-gas chamber in a fuel battery 1. Here, in order to curtail the amount of the inert gas, a substitution valve 17 which is installed in an outlet pipe 16 desirably should by throttled or closed according to the output signal of the detector 19; thus a bomb 15 of a smaller capacity can be used. Consequently, O2 gas in the oxidizing-agent-gas chamber in the fuel battery 1 is replaced with N2 gas, and thereby DC overcurrent can be prevented from reaching a critical level by a simple means. Furthermore, the N2-gas bomb can be omitted by using the N2 in the air.

Title: Node bypass reporting method
Inventor: KURIHARA KAZUMASA
IPC: H04L12/437
Filed: 1991-04-04
Abstract: PURPOSE:To improve the efficiency of maintenance operations by discriminating bypass caused by the fault of an adjacent node corresponding to a detected reception address at a ring-shaped network and reporting the bypass to all the nodes. CONSTITUTION:Respective nodes A, B and C respectively transmit/receive address report packets through optical fibers 3-1 to 3-6 at suitable time intervals. Each node compares a transmission address loaded on the received report packet with the address of the upstream side adjacent node previously stored in the present node. When those addresses are the same as the compared result, it is judged that the network is normal but when they are different, it is judged that the upstream side adjacent node is bypassed, and the generation of bypass is reported to all the other nodes by packets. Thus, all the nodes can speedily grasp the generation of faults at the other nodes and enable required correspondent processing, and efficient dealing is enabled for the maintenance operations.
