Filed: 1983-03-28
Abstract: PURPOSE:To attain the effective utilization of a buffer memory by transmitting information relating to a packet data length at a transmission side prior to the transmission of the packet data and preparing a receiving data buffer suitable for the packet data length at a receiving side. CONSTITUTION:When a data is transmitted to a computer 19 from a computer 11 via a packet exchange network, a main processing unit 12 decides the packet data length and transmits the length to a signal generating section 15, causing the section 15 to form a receiving request signal added with the information concerning the length of the data packet and the signal is transmitted to the computer 19. A signal detecting section 112 of the computer 19 extracts the information concerning the data packet length from the receiving request signal and transmits the information to a main processing unit 110. The main processing unit 110 matches the received data buffer length in a memory 113 with the data packet length. After the signal detection section 112 transmits a receiving preparation end signal, the data transmission and receiving are performed.

Title: Control rack trouble detector
Inventor: KOSHIZAWA TOSHIBUMI
IPC: F02D1/00
Filed: 1989-03-06
Abstract: PURPOSE:To detect a symptom of trouble by forecasting the range of a position, where a control rack is shifting, in advance in consideration of the effect of engine speed to control lever opening in a specified range, and when it is not shifted to the forecasting range, making it so as to be judged as something trouble. CONSTITUTION:When control lever opening K is made larger than the specified value K1, if movement of a control rack 17 is performed normally without being checked by dust or the like, naturally, engine speed grows larger than a first specified value N1, or a signal of a rack sensor 3 ought to come larger than a first specified value R1 (N1 and R1 are set to a suchlike value in advance). If the movement of the rack 17 is not normally performed, the engine speed is smaller than the specified value N1 and the rack sensor signal remains in a state of being smaller than the specified value R1. A first trouble detecting means detects this state, judging it as something trouble. A second trouble detecting means is also applied correspondingly to the above. Then, judgement in an (a) direction is performed by the first trouble detecting means and judgement of a (b) direction by the second trouble detecting means, respectively.
