Patent JP-H08312734-A (JP)
Title: Automatic transmission
Inventor: IBARAKI TAKATSUGU
IPC: F16H3/62
Filed: 1995-05-23
Abstract: PURPOSE: To decrease dragging torque and to achieve miniaturization and light weight by selectively transmitting driving force from an input element to a first planetary gear mechanism and a second planetary gear mechanism through a clutch, and transmitting it to the output element through a process of accelerating, decelerating or reversing it. CONSTITUTION: Driving force is transmitted from an input shaft 1 to a sun gear 5 in a Ravigneaux-type planetary gear mechanism 4 through a clutch C1 and a synchronous connecting mechanism K1. Since a carrier shaft 17 integrated with a carrier 8 in the Ravigneaux-type planetary gear mechanism 4 is connected to a casing 16 through a synchronous connecting mechanism B3 and a hub sleeve S3, it is made into the fixed state. In the Ravigneaux-type planetary gear 4, a ring gear 9 is rotated in the same direction as the sun gear 5 at a speed lower than that of the sun gear 5 since the sun gar 5 is driven in a state where the carrier 8 is fixed. Driving force decelerated by the Ravigneaux-type planetary gear mechanism 4 is transmitted to an output shaft 2 through output gear pairs 11, 19.

IPC: A47J43/06
Filed: 1990-06-05
Abstract: PURPOSE:To eliminate the need of mixing up even in the case of cooking together food which is apt to be burned by holding a container at a prescribed temperature and intermittently operating a motor at prescribed time interval by a controller for inputting an output of a temperature detecting part for detecting a temperature of the container, controlling an electric conduction to a heater, and also, controlling the operation of the motor. CONSTITUTION:A controller 18 detects a temperature of a container 5 by a temperature detecting part 19 consisting of a thermistor and controls an electric conduction to a heater 3, keeps a temperature of the container 5 constant, and also, can operate a motor 1 by selecting a mode for executing a continuous operation or an instantaneous intermittent operation of several times in one minute by manual operation. At the time of cooking food, for instance, when food is put in after attaching a cutter base 9 to the inside of the container 5, and a cover 15 is placed thereon and the controller 18 is operated, the food can be heated to a prescribed temperature by the heater 3, and simultaneously, when the motor 1 is operated in an intermittent operation mode, the cutter base 9 often mixes up the food and it can be heated uniformly without being burned.
