Title: Method and device for optical transmission
Inventor: TAKANO ISAMU
IPC: H04B10/50
Filed: 1995-03-31
Abstract: PURPOSE: To obtain an optical transmission system which may occupies a narrow band as an equalized amplifying circuit and is sufficiently tolerant of mark rate variation by converting an NRZ code received signal into a differential equalizing and amplifying circuit and performing DC regeneration and timing extraction. CONSTITUTION: The equalizing and amplifying circuit 2 inputs the NRZ code received signal to a differentiating circuit 24 to generate the differential equalized signal. A DC regenerating circuit has a logic circuit 31 which outputs the logic plus and logic minus signals of the differential equalized signal from the circuit 2 and a flip-flop circuit which is set with the logic plus signal and reset with the logic minus signal. At the input terminal of a timing discriminating circuit 4, a full-wave rectifier circuit 42 is provided to rectify the differential equalized signal. Consequently, the DC regenerating circuit which may have a narrow band and is highly practical is obtained as the equalizing and amplifying circuit and the optical transmission equipment is obtained which is sufficiently tolerant of mark rate variation and can be IC-implemented.

IPC: B60T8/24
Filed: 1990-03-27
Abstract: PURPOSE:To enable it to secure high responsiveness even in the case of sudden steering input by varying each wheel braking force between both turning inner and outer sides at time of turning and generating a yaw rate, while constituting it to determine the braking force difference according to even steering speed. CONSTITUTION:In this controller, there are provided a turning state detecting means A detecting a car turning state and a steering speed detecting means B detecting a steering speed, and each output signal out of these detecting means is inputted into a wheel braking force setting means C. In response to each signal out of these detecting means A, B, each wheel braking force is varied between both turning inner and outer sides so as to produce a yaw rate in the vehicle according to a turning state at time of car turning, while the braking force difference is made so as to be set according to the steering speed. With this constitution, the braking force difference comes to be determined in consideration of even the steering speed, so that in regard with yaw rate, using a suchlike braking force difference, such conformed to the turning state and the steering speed can be generated, thus the extent of responsiveness is enhanced and, what is more, a driver's steering feeling is improved.

Filed: 1982-05-06
Abstract: PURPOSE:To perform automtic drawing by sending a driving signal for moving a condenser lens forcibly when at least either of an information and an error signal has a value beyond the range of depth of focus of the condenser lens. CONSTITUTION:An error signal 8 and an information signal are applied to an NOR circuit 12 through a rectifier 15 and a low-pass filter 16.

Title: Production of polarizing film
Inventor: TANAKA NOBUO
IPC: B29L7/00
Filed: 1993-04-01
Abstract: PURPOSE:To improve polarization performance of a polarizing film even when the film is obtd. at low temp. and uniaxialy orientated, by uniaxially orienting a film having specified weight ratio of cold water-insoluble polyvinylalcohol and cold-water soluble polyvinylalcohol. CONSTITUTION:This polarizing film is produced by uniaxially orienting a film comprising polyvinylalcohol having >=50 deg.C complete dissolving temp. in water (PVA insoluble with cold water) and polyvinylalcohol having <=30 deg.C complete dissolving temp. (PVA soluble in cold water) with the weight proportion of A/B is 98/2-70/30. If the mixing proportion A/B exceeds 98/2, the effect to improve the orienting property of the PVA film is not enough. If the proportion is smaller than 70/30, practical strength required for the polarizing film decreases. Thereby, the polarizing performance of the polarizing film by low temp. orientation can be significantly improved, and the obtd. film has const. transmittance and excellent polarizing performance.
