IPC: G02B13/00
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a simple and inexpensive optical system which can satisfactorily converge the image beams on a photosensitive area of an electronic sensor by adding an area array of pixels to the electronic sensor to detect the image beams and placing a field lens approximately on the optical path of the image beam. SOLUTION: A pseudo telecentric lens 480 is prepared to converge the image beams 418, 420 and 422 on an electronic sensor 416 together with a field lens 482 which is placed between the lens 480 and the sensor 416. The lens 482 functions as a positive lens, i.e., a converging lens that varies the direction of the optical path passing through the lens 482 by the refraction. The positive lens has a positive focal distance to converge the beams which are parallel to the lens axis and sets the image beams 418 and 422 having incident angles not equal to zero in parallel to the lens axis. The lens 482 is attached at a position near the sensor 416 so as to hardly affect the performance of other parts of an optical system.

Title: Motor controller
Inventor: ARAKAWA NOBUAKI
IPC: H02P27/06
Filed: 1992-10-26
Abstract: PURPOSE:To stabilize voltage to be applied to a motor through a controller comprising a converter for switching between full-wave rectification and voltage doubler rectification by modifying the reference voltage for the output voltage from the converter at the time of switching and correcting output voltage signal from an inverter control circuit based on a DC voltage detected. CONSTITUTION:At the time of switching from full-wave rectification to voltage doubler rectification or from rectification to full-wave rectification, reference voltage for the output voltage of a converter is set based on a previously calculated time constant of the terminal voltage of a smoothing capacitor 3. Voltage conversion rate of an inverter 5 is then modified according to the reference voltage thus sustaining the output voltage at a constant level. On the other hand, a voltage detector 4 detects terminal voltage of the smoothing capacitor and corrects the voltage conversion rate of the inverter 5 based on the terminal voltage thus detected. This constitution suppresses instability of the voltage to be applied to a motor 6 even when the time constant of the terminal voltage of the smoothing capacitor 3 is altered due to fluctuation of the load on the motor 6 or the like.
