Title: Data saving/recovering system in data transfer system
Inventor: KONNO MASUMI
IPC: H04L69/40
Filed: 1987-06-02
Abstract: PURPOSE:To eliminate the loss of transfer data by detecting the overflow of a memory saving transfer data and saving in a file means data after overflow. CONSTITUTION:If a fault detection part 12 detects the fault of a data communication line 3, a control part 13 saves transfer date of a data transmission part 10 in the memory 14. An overflow detection means 15 supervises the saving state of the memory 14 and informs the control part 13 of the overflow of the memory 14. The control part 13 controls a switching part 11 and saves transfer data of the transmission part 10 in the file means 100. The data medium of the file means 100 is set in the file read means 200 of transfer destination. With the setting, a switching means 21 operates and it switches and connects a data reception means 20 to the read means 200. Consequently, the data medium is read by the read means 200 and reproduced data is transmitted to the reception part 20, whereby data is recovered. Thus, the loss of transfers data can be eliminated.

IPC: F02D1/04
Filed: 1987-06-03
Abstract: PURPOSE:To restrain the maximum rotational speed of an engine during operation at a low temperature and to prevent white smoke from being produced, by forming a governor spring for determining the maximum rotational speed of the engine from shape memory alloy so that the force of the spring may be decreased when the temperature of the engine is low. CONSTITUTION:When the rotational speed of a Diesel-engine increases, the centrifugal force exerted to flyweight 14 increases so that the urging force exerted to a shifter 18 by a roller 20 is increased. As a result, a tension lever 24 swings about a fulcrum 26 overcoming a governor spring 50 so that the fulcrum 42 is displaced rightward, and accordingly, a control rack 52 is displaced rightward. Accordingly, the discharge amount of fuel from an injection pump 10 is decreased. In this arrangement, the spring force of the governor spring 50 made of shape memory alloy is decreased when the temperature of the engine is low. Thereby the tension lever 24 is urged by a small force when the temperature of the engine is low, thereby it is possible to decrease the torque of the engine.
