Filed: 1981-11-20
Abstract: PURPOSE:To obtain a color picture having good resolution, by providing a tri- color filter and an electronic shutter in front of a black-and-white cathode-ray tube. CONSTITUTION:On a fluorescent surface 1a of a black-and-white cathode-ray  tube 1, one scanning line is drawn by a red component in a color television picture signal. At the same time, when voltage is applied to a red color electrode  group among 3 electrode goups of a PLZT element 11, the polarizing surface is  rotated as to only its part. As a result, by polarizing plates 10a, 10b, as for only  its part, light of the cathode-ray tube passes through the red part of a filter 4,  and as for other part, it does not pass through. In the same way, when scanning  and driving of the electrode group are executed synchronously to blue and green colors, too, an observer 6 is able to see a color picture through a window 3.

Inventor: SUZUKI JUNJI
IPC: H04J3/02
Filed: 1984-09-07
Abstract: PURPOSE:To minimize deterioration in quality of voice and to transmit voice and data simultaneously by allowing a coding section and a decoding section to switch the code rule synchronously when a forecast coefficient detection circuit of transmission side and a reception side detects respectively that the forecast coefficient is at the outside of a prescribed range. CONSTITUTION:A tone signal generator 1 uses a data transmission request signal RE to output a tone signal of a predetermined specific frequency and a switch 3 switches a voice signal into a tone signal for a prescribed time to input it to a low-frequency coding section 2. When the tone signal is cut off after a prescribed time, a forecast coefficient detected by forecast coefficient detection circuits 5, 9 exceeds a prescribed range. Thus, the other coding rule reducing bit number is switched to the low-frequency coding section 2 and the low-frequency decoding section 10, which are operated in the data simultaneous transmission mode. Further, a multiplex circuit 8 at the transmission side inserts a data signal D to a low-order 1 bit of e.g., a low-frequency coding section 2, outputs the result multiplexedly and a separating circuit 14 at the reception side outputs separately the corresponding bit as the data signal D.

Title: Continuously variable transmission
Inventor: TAKEMOTO HARUKI
IPC: F16H9/12
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a continuously variable transmission capable of shortening an input shaft, eliminating an accurate machining, and feeding lubricating oil smoothly to a primary pulley side. SOLUTION: An input shaft 3a and a primary pulley 50 are disposed in the state of being separated from each other, and a lubricating oil guide member 28 mounted on either of the input shaft and primary pulley is installed between an oil passage 3b of the input shaft 3a and an oil passage 52c of the primary pulley 50 so that lubricating oil passes through these oil passage. The lubricating oil guide member 28 eliminates the need that the input shaft 3a must be inserted engagedly into the oil passage 52c of the primary pulley to guide lubricating oil and also eliminates a highly accurate machining, making this transmission economical.  Even if a rotating difference occurs between the input shaft and the primary pulley 50 by reverse operation, because the input shaft 3a and the primary pulley 50 are in the state of being separated from each other, the input shaft 3a is prevented from being in contact eccentrically with the primary pulley 50. In addition, a seal ring between both of them can be eliminated.
