Title: Navigator
Inventor: WATANABE HIRONOBU
IPC: G01C21/12
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a navigator which prevents an increase of position correction errors by a multipath by detecting reflection by an obstacle when receiving signals of a GPS satellite. SOLUTION: A position-estimating means 3 calculates an estimated position of a machine with use of a move distance and an angular shift amount. A distance-calculating means 5 calculates a distance between a position of the machine and a position of a receive satellite. A multipath-detecting means 6 compares a signal propagation time of a GPS signal and the distance calculated by the distance-calculating means 5, detects a multipath and controls not to correct the position according to a GPS when the multipath is detected. An increase of position correction errors is accordingly prevented.

Title: Engine torque fluctuation absorbing device
Inventor: TOZAWA SATORU
IPC: B60W20/00
Filed: 1992-12-29
Abstract: PURPOSE:To provide an engine torque fluctuation absorbing device absorbing the torque fluctuation of an engine during the idling operation. CONSTITUTION:During the idling operation, the field current is fed to a synchronous AC machine 2-1 directly connected to an engine from a battery 9 for the power generation action, and the output voltage of an inverter 7 is invariably applied while the battery 9 serves as a power source. When a rotation fluctuation occurs to increase the revolving speed of the engine, the phase of the inverter output voltage against the generated voltage is controlled based the detection signal of a rotor position detector 6 so that the synchronous AC machine 2-1 generates the torque hindering the rotation of the engine. When a rotation fluctuation occurs to reduce the revolving speed, the phase of the inverter output voltage against the generated voltage is controlled so that the synchronous AC machine 2-1 generates the torque to assist the rotation of the engine. The phase can be quickly changed, and the responsiveness of the control is good. The phase can be continuously changed little by little, the magnitude of the generated torque can be freely changed, and the rotation fluctuation is properly absorbed.

Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a heat utilization system utilizing hydrogen-storage alloy which does not incur the fragility breakage caused by hydrogen, even if stainless material excellent in pressure resistance is used as an alloy container to accommodate hydrogen-occluding alloy. SOLUTION: A heat exchanger 8 is one where ring discs R in each of which a plurality of alloy storage rooms 10 are made radially by a pair of plates 12 and 13 are stacked, and copper layers are made at the inner surface of the alloy storage room (the first to third containers S1-S3) that hydrogen touches.
