IPC: F16H3/62
Filed: 1989-03-20
Abstract: PURPOSE:To increase the range of gear ratio by transmitting a driving force from a first and second planetary gear mechanisms to a third planetary gear mechanism in the lowest speed change gear stage and to the third planetary gear mechanism by accelerating the driving force by the fourth planetary gear mechanism in the highest gear stage. CONSTITUTION:The captioned speed change gear has a first planetary gear mechanism 21 into which a driving force from the output shaft 102 of a torque converter is inputted via a first clutch 31, a second planetary gear mechanism 22 into which the driving force is inputted via a second clutch 32, a third planetary gear mechanism 23 for outputting the driving force after speed change and a forth planetary gear mechanism 24 for overdriving. A ring gear 222 and a carrier 223 are commonly used for the second and fourth mechanisms. The driving force is transmitted from the first and second planetary gear mechanisms 21, 22 to the third planetary gear mechanism 23 in the lowest speed change stage while transmitting the driving force to the third planetary gear mechanism 23 after accelerating same by the fourth planetary gear mechanism 24 in the highest speed stage, to be outputted from an output shaft 206. Thereby, the gear ratios of the first and fifth gears can be simply set without need for considering other speed change stages, enabling the range of gear ratio to be increased.

Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a light transmitter which can precisely control a quenching ratio even if the output characteristic of a current to light in a laser diode changes by detecting the fluctuation of the quenching ratio with the output amplitude fluctuation of a preamplifier thereby controlling bias current. SOLUTION: A digital signal inputted to a DATA input terminal 1 is converted into modulation current Imod and it drives a laser diode 3 with bias current Ib. A part of a light signal outputted from the laser diode 3 is inputted by a photodiode 5 and is converted into a current signal. The current signal is converted into a voltage signal by a preamplifeir 6. A voltage amplitude value is kept by capacitive load by a peak detector 7 and a voltage value proportional to the voltage amplitude value is outputted. A bias current controller 8 inputs output voltage and controls the size of bias current Ib outputted from a bias current source 4 so that inputted voltage becomes constant.

Title: Method for controlling electric air valve of bubble generating bathtub
Inventor: NAKAOKA TAKAYOSHI
IPC: A61H23/00
Filed: 1995-03-27
Abstract: PURPOSE: To quickly set the precise position state of an outlet port by setting the position of the outlet port turned to a nozzle side passage of a valve element by the integrated rotating time between the valve element outlet port and its interrupting position from a standard position detected by a position detecting means, and making the rotating direction of the valve element and the valve element rotating time the shortest. CONSTITUTION: For positions turned to a nozzle side passage of a valve element outlet port differed in opening area, the outlet port is opened in small, middle, large and full open states including full close state, and the time required for the rotation of the valve element between each level is set to, for example, 2 seconds from full close to small open, and 1.8 second from small open to middle open. In a Hall element control section CH and a time control section CT as detecting means, the full close and full open positions are set to 90 deg.. To make the rotating position of an electric air valve the shortest, for example, the rotating time between each level is increased by 100 times, and managed by this value, and the rotating direction is determined, considering a difference in level.  When the rotating direction is switched, a motor is rotated excessively by the portion of back flash time.
