Abstract: A command from a host computer is held in a command holding section, and commands set in a register are referenced to determine whether or not the held command involves data transfer. If the command involves data transfer, a switching signal output section outputs switching identifying signals SX and SY to a command switching section. Thus, the command involves data transfer, control is provided by a hardware configuration without using a CPU. Alternatively, when the command involves no data transfer, the switching signal output section outputs an interrupt to the CPU. The CPU interprets the command held in the command holding section to output the switching identifying signals SX and SY to the command switching section.

Abstract: A multi-axis light beam type sensor with a simple fail-safe sensor system which stops when the sensor system is abnormal (logic value "0") is provided. The construction is such that scanning output signals for synchronously driving respective light emitting elements (LD) and light receiving elements (PD) positioned facing each other are generated using shift registers. A normal or abnormal condition of the scanning output signals is judged based on an output of the light transmission side shift register (5), using an addition operation in a scanning output signal checking circuit (9). Moreover, coincidence or non coincidence of last stage outputs of the respective shift registers of the light transmission and light reception sides, is determined by a coincidence detecting circuit (10).

The scan circuit has a failure detector that provides, upon detecting a failure, a signal of logical value 0 to inform of the failure. Adjacent input signals to the failure detector have a phase difference of .pi.. This phase difference results in simplifying the structure of the failure detector. The fail-safe scan circuit is employable to drive and scan many photosensors of a fail-safe multibeam sensor.

This circuit is simple and capable of lowering an output level.

Abstract: A detecting device can centrally monitor and detect a lamp failure of one or more lamps connected in series such as guide lamps in the runway of an airfield. A core (12) is disposed on a power line (P.sub.1) of each lamp (L.sub.1 -L.sub.n). The power line (P.sub.1) is wound on the core (12) as a first winding (N.sub.1). A second winding (N.sub.2) for extracting the power of the power line (P.sub.1) is wound on the core (12). An oscillator (13) is provided which uses the output voltage of the second winding (N.sub.2) as the power supply to generate a frequency corresponding to each lamp (L.sub.1 -L.sub.n). The output signal from this oscillator (13) is fed back to the power line (P.sub.1) through a third winding (N.sub.3). Accordingly, a signal consisting of a frequency which represents each lamp flows through the lamp circuit and any failed lamp or lamps can be detected by checking this feedback signal.

Abstract: A thermal head in which a glazed layer, an improved undercoat layer, a heat generating resistor layer, an electrical power supply conductor layer and a protection layer are successively laminated to the surface of an insulating substrate, in which the undercoat layer is composed of an aluminum nitride (AlN) film. The method of manufacturing the thermal head comprises forming the aluminum nitride (AlN) film by sputtering an Al target in a gas mixture of argon and nitrogen and forming the heat generating resistor layer and the electrical power supply conductor layer, that is, three layers in total successively formed by sputtering. Because of the good heat conductivity of aluminum nitride film, the temperature distribution in the heat generating portion is made uniform and localized heat generation can be avoided, as it also prevents the destruction of the heat generating resistor layer or the protection layer due to the temperature difference upon heat generation.
