摘要： A tape cassette device comprises a cassette case in which a stationary reel with a tape guide path is housed, and an endless tape wound on the outer circumference of said stationary reel, the innermost part drawn out along said guide path to the inside of said stationary reel to be wound on the outer circumference of said stationary reel. Said case has a bottom plate having a scanning head and a tape drive mechanism inserting opening located at the inside of said stationary reel. A pair of sliders are disposed inside said cassette case, which are displaceable between a lower position where it is located at the side of said bottom plate for closing said opening and an upper position where it is located away from said bottom plate for opening said opening.

摘要： A survey system is provided having GPS receivers and using a global positioning system. A reference station main body is provided for surveying; and a plurality of GPS survey apparatuses are provided. They include at least a reference station and a measuring station. The reference station main body has a coordinate composite conversion unit which composes a composite coordinate value of a single coordinate system from GPS data input via an input portion and reference station data measured at the reference station main body. An output device outputs the coordinate value composed by the coordinate composite conversion unit.

摘要： A signal transmission system which perform two-way signal transmission between a first transmitter-receiver and a second transmitter-receiver via a pair of signal lines and supplies a DC current from the first transmitter-receiver to the second transmitter-receiver. In each of the first transmitter-receiver and the second transmitter-receiver, there are provided a current varying circuit for varying a signal line current by a transmission pulse signal so that the signal line current may assume a value in a predetermined current region lower than a minimum level of a load current to the other transmitter-receiver during sending out a signal pulse, a current detector for detecting a current or voltage variation in the signal line current, and a gate circuit for blocking the detected output from the current detector while the transmission pulse is sending out to the current varying circuit.
