Title: Time division type optical switch
Inventor: KUROYANAGI TOMOJI
IPC: H04B10/27
Filed: 1991-11-28
Abstract: PURPOSE:To reduce loss and to enable high-speed operation by comprising the switch of a switch module in which switch elements replacing time slots are arranged at each cross point of wiring. CONSTITUTION:In a switch module 20, switch elements (SE) 30 replacing the time slots are arranged at each cross point of the wiring arranged in the shape of matrix inside the module. Signals having time multiplexing degree (m) of time slots TS1 to TSm are inputted to k (number) highways #1 to #k, and m (number) multiplexed signals are outputted from the switch module 20. Thus, by providing the switch elements 30 which operate as shown above at each cross point within the switch module 20, a time division type optical communication path (optical switch) not requiring a space switch can be realized.

Title: Autoleveling device for head lamp of automobile
Inventor: TODA ATSUSHI
IPC: B60Q1/115
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To allow a highly accurate correction of an optical axis without an effect of mounting tolerance of a height sensor itself. SOLUTION: A pitch angle of a vehicle corresponding to an output of a height sensor 14 mounted at a suspension is calculated, and based thereon an actuator 10 is controlled to move an optical axis L in a headlight 1 up and down. The actuator 10 works from 2 foremost stroke position (last end position) where the pitch angle is 0 and the optical axis is properly located in the direction of lowering the optical axis.  An arithmetic control unit 30 controls operation of the actuator 10 with respect to an assumed initial position PO' by subtracting the output ΔH equivalent to the offset value, and calculating the pitch angle corresponding to the output which is the output H of the car height sensor on the assumption that the position offset in the direction of raising the optical axis to the extent of the stroke corresponding to the maximum mounting tolerance of the height sensor 14 is considered as the initial position PO'.
