IPC: F16H9/00
Filed: 1994-06-16
Abstract: PURPOSE:To secure safety when a shift position detector is abnormal, by setting the shift position in the reverse position in starting of an engine when all bits of an output signal from the shift position detector is in their off state, and setting the shift position to the shift position evacuated to a memory means during the operation of the engine. CONSTITUTION:In a control circuit 20 of a continuously variable transmission, an R range is set in the memory range for evacuation of the shift position variable, into which an output signal from a shift position detector 16 is to be stored in starting of an engine. Next, the output signal is read from the shift position detector 16 into the shift position variable, so as to take out the subordinate six bits of the shift position variable. Whether or not all six bits wherein the shift position variable corresponds to the shift position is in the off state is judged. When the result is YES, the shift position held in the evacuation range is set by the shift position variable. Moreover, when the engine is operated, for example, when the just before shift position is in the D range, the D range is set by the shift position variable.

Filed: 1990-06-15
Abstract: PURPOSE:To facilitate connection of a tape fiber by disposing a light signal emitting part so that a demultiplexed light signal is emitted from the end surface of a cladding layer different at every wave length. CONSTITUTION:A photo signal is inputted to respective optical multiplexing/ demultiplexing waveguides 3a - 3d, where the light signal is branched into a light signal of wavelength lambda1 is propagated through linear waveguides 6a - 6d and emitted from light signal emitting parts 9a - 9d on the end surface R side.

Title: Dynamic brake for brushless synchronous motor
Inventor: KURAUCHI SHIGERU
IPC: H02P6/08
Filed: 1989-06-21
Abstract: PURPOSE:To inexpensively brake a motor in a motor low speed rotating range without necessity of a mechanical unit at a motor shaft by adding a device for consuming generating energy of a brushless synchronous motor to an inverter for driving the motor. CONSTITUTION:When a braking transistor 6 ia turned ON by a brake controller 9, 3-phase induction voltages are three-phase full-wave rectified by flywheel diodes DX-DZ and rectifying diodes DX'-DZ'. Further, a braking resistor 5 consumes as thermal energy due to the flow of a current by a full-wave rectified voltage. Accordingly, since a deceleration torque is consumed as generating energy via the resistor, braking time can be shortened as compared with the case in which it is stopped only by mechanical loss.

Abstract: PROBLEM TO BE SOLVED: To surely suppress fluttering generated when a door is closed by making the gravity center position of the door substantially coincident with the center of a reaction force received by the door from a weather strip at the time of closing the door. SOLUTION: The gravity center G of a door 1 is positioned in a place roughly symmetrical to the left and right directions thereof. On the other hand, the gravity center G is shifted to a lower side from the upper and lower center of the door 1 and the spring constant of a weather strip 10 is set to be low in an upper side more than the position of the gravity center G [i.e., in the part of the upper side (2) of a virtual line A passing through the gravity center G] and high in its lower side [i.e., in the part of the lower side (1) of the virtual line A passing through the gravity center G] and thus the center E of a reaction force is made substantially coincident with the gravity center G.  In other words, by making a moment around the gravity center produced in the upper side of the virtual line A at the time of closing the door equal to that produced in the lower side at the time of closing the door, the fluttering of the door 1 is suppressed.
