IPC: H04L23/00
Filed: 1988-11-25
Abstract: PURPOSE:To shorten an image data communication time in average by discriminating data quantity and decreasing the effect of a load onto a network in response to the data quantity or minimizing the time delivered to an opposite station. CONSTITUTION:When an image data transferred to other station and not compressed exists in a main storage device 4, a control section 3 allows a communication quantity monitor 8 to calculate a communication load quantity at that point of time, compares the value with a predetermined reference value, and when the value is higher than the reference value, the transferring image data is encoded and compressed by a compressor 5 and the compressed image data is sent to a local area network 2 by a communication controller 6. When the communication load quantity is lower than the reference value, the image data is singly sent to the communication controller 6. Thus, the communication time of the image data of end-to-end is decreased in average.

Title: Transmission method
Inventor: KOMIYA TOSHIO
IPC: H04B3/56
Filed: 1992-11-09
Abstract: PURPOSE:To transmit polarity information and counting information with one transmission channel and to transmit both information in real time by producing and sending a count signal with a pulse which is reversed whenever the polarity is changed. CONSTITUTION:Two signals (CP/DIR signal) with the polarity information and counting information are compressed to produce one output bit signal (OB signal) and sent by one transmission channel 15. The OB signal has a binary rectangular wave and is taken as an H active counting pulse signal when the polarity is positive and taken as an L active counting pulse signal when the polarity is negative. In short, the CP/DIR signal inputted to the transmission circuit 11 is compressed to produce the OB signal, which is sent along the transmission path 15 and the OB signal inputted into the reception circuit 13 is converted into an UP/DOWN signal. Thus, the two input signals can be transmitted with one transmission channel in real time.

Title: Distance measuring apparatus
Inventor: AKASU MASAHEI
IPC: G01S17/10
Filed: 1990-11-02
Abstract: PURPOSE:To obtain an inexpensive apparatus by enhancing distance detecting function to a large extent and using pulse laser low in light emitting output by averaging the signal of a reflected pulse beam to improve an S/N ratio and reducing the erroneous operation due to noise. CONSTITUTION:The pulse beam emitted from a pulse laser 1 is reflected from an object 10 and a photodetector 3 inputs the reflected pulse beam to photoelectrically convert the same and the obtained electric signal is amplified to be outputted. The output signal of the photodetector 3 is converted to a digital signal by an A/D converter 4 and this A/D conversion is repeated unit the counting of an address generator 6 is stopped. For example, when the number of times of the emission of pulse beam reaches 16 times and the A/D conversion results of the reflected pulse beams corresponding to 16 times are stored in the respective regions of a memory 5, a processing circuit 7 averages the A/D conversion results of the reflected pulse beams of 16 times. The time from the emission of the pulse laser 1 to the peak of reflected pulse beam is calculated from the generation order of the peak of the average reflected pulse beam to be converted to a distance. By this method, distance detecting capacity is enhanced and pulse laser low in beam emitting output can be used.

Then, if the light beam having plural light axes is interrupted by an object in the detecting area A due to a person, the outputs of their axes become '0'. An amplifying/level detecting circuit 6 processes a signal from the light- receiving circuit 2a, generates a detecting signal and outputting this.  Then, the output of an optical sensor array is inputted to a CPU processing unit 10 and whether the object is a train, person, etc., is determined, based on how the light beam of the optical axis has been interrupted.
