Filed: 1988-10-21
Abstract: PURPOSE:To prevent the deterioration of an extinction coefficient according to the decrease of the quantizing efficiency of a laser diode due to a temperature rise by connecting the output of a temperature gain converting circuit to a current source transistor-(TR) of a driving circuit. CONSTITUTION:A temperature gain converting circuit 21 is provided, the output of a time constant circuit 20 constituting an optical output control circuit is branched, connected to the temperature gain converting circuit 21, and the output of the temperature gain converting circuit 21 is inputted to the base of a current source TR 14 of the constant current source of a driving circuit 12. Consequently, since the base voltage of the TR 14 rises as the temperature rises, and a pulse current to drive a laser diode 11 is increased according to the decrease of the quantizing efficiency of the laser diode 11. Thus, even when the laser diode in a 1.5mum band, where the quantizing efficiency decreases at the higher temperature, is used, a transmitting circuit not to degrade an optical waveform and the extinction coefficient can be realized.

Title: Controller for automatic transmission
Inventor: OKAHARA HIROBUMI
IPC: F16H59/24
Filed: 1989-10-11
Abstract: PURPOSE:To restrain the occurrence of gear change shock during double reciprocal gear change by deciding the starting time of a main or auxiliary transmission, which is gear-changed later, in accordance with vibration periods which appear immediately after prior transmission starts gear-changing. CONSTITUTION:A main transmission (a) and an auxiliary transmission (b) are synchronized to conduct double reciprocal gear change, that when one is upshifted the other is downshifted. In this case, a gear change priority deciding means (d) gives change with either the main transmission (a) or the auxiliary transmission (b) in priority in accordance with signals from a double reciprocal gear change detecting means (c). The starting time of either transmission which is gear-changed later is decided by a gear change delaying means (f) in accordance with vibration periods, detected by a detecting means (e), which appears immediately after prior transmission starts gear-changing, so that the phases of prior gear change vibration and following gear change torque variation can be always reverse. It is thus possible to reduce gear change shock.
