Title: Starter with shunt coil
Inventor: YUGAWA YASUAKI
IPC: F02N11/00
Filed: 1982-10-29
Abstract: PURPOSE:To increase the braking effect of an armature by concentratedly flowing a current generated by back electromotive force due to the inertial rotation of said armature into a shunt coil without leaking it to the coil of a magnet switch. CONSTITUTION:When a current is about to flow from a motor terminal 6 to a pull-in coil 3, a diode 5 which functions in the opposite direction prevents its flow, but, when starting, the diode functioning in the normal direction conducts a current from the pull-in coil 3 to the motor terminal 6. When a switch 2 is opened after operating a starter, an armature 9 continues to rotate by inertia, generating back electromotive force. A current generated by this back electromotive force flows from the armature 9, through a field coil 8, and to a shunt coil 10, which is turn, being excited by the back electromotive force, operates so as to brake the rotation of the armature 9. The back electromotive force which is about to flow to the pull-in coil 3 is prevented by the diode 5.

Abstract: PURPOSE:To prevent a vehicle from abruptly starting upon backward movement, by injecting a basic injection amount of fuel upon forward movement of the vehicle, and as well by injecting an amount of fuel which is slightly smaller than the basic fuel injection amount, upon backward movement of the vehicle. CONSTITUTION:When it is judged that a shift switch is turned on, a backward accelerator opening degree conversion value AccR is compoted at the step 303. meanwhile, when the shift switch is turned off, a forward accelerator opening degree conversion value AccF is computed at the step 304.

Title: Manufacture of optical fiber
Inventor: TAKAHASHI SHIROU
IPC: C03B37/023
Filed: 1983-10-14
Abstract: PURPOSE:To obtain a uniform optical fiber preventing the crystallization, by extruding molten glass from a high-temperature crucible through a nozzle having the nozzle opening directed upward, quenching the extruded glass near the tip of the nozzle, and drawing the spun fiber upward. CONSTITUTION:Molten glass 1 is formed in the platinum crucible 3 by lowering and melting the raw material rod 2. The molten glass 1 overflowed from the nozzle 4 is quenched e.g. to 300 deg.C with the cooling pipe 6 just after extruded from the nozzle 4, and taken up as the optical fiber 7. Since the opening of the spinning nozzle is directed upward in the present process, the dripping of the molten glass heated above the melting point can be prevented, and the spinning of the fiber can be carried out continuously. Furthermore, since the molten glass is quenched and solidified rapidly from the molten state, a uniform optical fiber can be manufactured without causing the crystallization even in the case of using an easily crystallizable glass such as a fluoride glass as a raw material.
