Title: Communications equipment for carrying truck
Inventor: MURAKAMI AKIRA
IPC: G05D1/02
Filed: 1991-11-29
Abstract: PURPOSE:To attain sure data communication with each transmitter while a carrying truck moves in transmission areas of plural transmitters with a different carrier frequency by setting a frequency of an oscillation signal to a demodulator based on a demodulation level of a received signal. CONSTITUTION:When a carrying truck 5 is resident around a center of a transmission area of a transmitter-receiver 4 whose frequency is f2, the carrying truck 5 makes data communication with the transmitter-receiver 4 whose frequency is f2 by using a carrier whose frequency is f2. When the carrying truck 5 is driven and moves to the transmission area of the transmitter-receiver 4 whose frequency is, e.g. f1, a demodulation level detected by a demodulation level detection section 64 is reduced according to the movement and the level is less than a reference demodulation level. Thus, an oscillation control 63 selects a frequency of an oscillation signal from an oscillation section 60 to find out an oscillation signal by which the level of the demodulation signal reaches the reference demodulation level or over.

Abstract: PURPOSE:To find a frame image at a time I+n by interpolation by calculating the motion vector of a body from three-dimensional amount of travel at the time I+n, and moving a time I and all the picture elements on I+k (k>) frames. CONSTITUTION:An images generating part 1 generates images from which hidden-surfaces from an arbitrary visual point are erased at time I and I+R from the shape data, the reflectivity of the surface, the pattern, and the illuminance on the surface of a three-dimensional body.

A central processor located at the sensor output processing section of a residual guantity display section 3 comprises a container weight determination means, a residual liquid quantity determination means, and a correction means. The container weight determination means determines the size of a container based on the initial weight measured by the sensors 1-1,..., 1-6 and the range of initial weight preset for each size of the weight thus determining the weight for a plurality of containers. The residual liquid quantity determination means determines the residual liquid quantity by subtracting the weight of container from the initial weight measured by the sensors 1-1,..., 1-6.  The correction means corrects the starting point of weight measurement at the time of replacing the container. The results are presented on the residual quantity display section 3 based on a control signal.
