Title: Pretrigger generating circuit
Inventor: MIYANAGA NARIYUKI
IPC: G01S7/12
Filed: 1988-12-23
Abstract: PURPOSE:To generate a pretrigger before a range zero trigger, to simplify a construction by a digital processing and thereby to obtain a highly precise circuit by applying a subtraction processing to a range zero trigger interval count value and an output of a range zero pretrigger interval value generator and thereby calculating a pretrigger generation distance. CONSTITUTION:A range zero trigger interval is counted by a range counter 3 reset by a range zero trigger 2 and is latched in a data latch 5. This latched value and an interval value set by a pretrigger interval value generator 6 are processed by a subtractor 8 to calculate a pretrigger generation distance, which is latched in a data latch 5. When a count value of the counter 3 and the distance latched in the latch 5 are in accord with each other, a pretrigger is outputted from a comparator 10. Even when an O range trigger period changes, accordingly, the pretrigger is always generated before an O range trigger, and also a pretrigger generating circuit is made simple in construction and highly precise by a digital processing.

Abstract: PURPOSE:To achieve prevention of hydrogen embrittlement of a base material of a cover pipe by arranging a metal barrier of a zirconium liner on an inner surface layer and further, a copper layer or the like between a liner layer and the base material of the cover pipe to block transmittance of hydrogen.

Title: Dc motor capable of regenerative braking
Inventor: BAN ITSUKI
IPC: H02P7/00
Filed: 1992-10-29
Abstract: PURPOSE:To obtain a reluctance-type motor and a brushless DC motor wherein their speed is high, their torque is high and their efficiency is excellent and to regeneratively brake the motors. CONSTITUTION:When the electricity-feeding operation of one excitation coil 39a is stopped, it is prevented that magnetic energy accumulated in a magnetic core is returned to the side of a power supply by a diode 49a for reverse-current prevention use, the energy flows into the small-capacity capacitor 47a, the capacity is charged and held at a high voltage and an electric current is dropped quickly. After a prescribed time, electricity is fed to a next excitation coil 39b. However, since an applied voltage at the time becomes a high charging voltage for the capacitor 47a, an electric current rises quickly. Since the electric current rises and is dropped quickly, the motor can be turned at tens of thousands of revolutions per minute, and the motor can be regeneratively braked by generating an arbitrary reversal torque by a chopper circuit by changing the motor to a reverse-rotation mode during a forward rotation.
