IPC: H03D7/14
Filed: 1989-04-21
Abstract: PURPOSE:To decrease the crossmodulation interference and to attain low noise and high gain by forming two differential amplifier section receiving a 2nd input signal such as a local oscillating signal with bipolar transistors(TRs) and switching the bipolar TRs completely. CONSTITUTION:A local oscillation signal Vosc is fed to bases of bipolar TRs BT1, BT4 and emitters of bipolar TRs BT2, BT3 in an opposite phase and the bipolar TRs BT1-BT4 are switched to improve the conversion efficiency. Thus, the frequency conversion is applied efficiently at a small local oscillation signal. The crossmodulation interference is caused at the input TRs of an input signal VIN but when the bipolar TRs BT1-BT4 are completely switched, since the input TRs consist of junction type field effect TRs FET1, FET2, no crossmodulation interference is caused.

Abstract: PURPOSE:To improve the durability, to simplify the structure, and to reduce frictional power of the gear in the title by providing a rigid ring engaged with a groove of a V-pulley, whose width changes, and changing the rigid ring in the radial direction by a control mechanism to change the speed change ratio between both pulleys. CONSTITUTION:When a ring 10 engages with the inner peripheral portion of a V-pulley 3 and the outer peripheral portion of a V-pulley 4, power is transmitted at a large reducing gear ratio from the pulley 3 to the pulley 4. When the ring 10 is moved in such a manner that the center line A approaches a rotary shaft 1, both flanges of the pulley 4 is expanded to be engaged with the inner peripheral portion and engaged with the outer peripheral portion of the pulley 3. When the position of the ring 10 is thus changed, the effective radius of the pulley 3 is increased, and the effective radius of the pulley 4 is decreased, so that the ring 10 transmits power from the pulley 3 to the pulley 4 in the accelerating state. Accordingly, by changing the position of a support 12 by means of a control device 13, the position of the ring 10 is changed through a guide roller 11 to change the effective radii of the pulleys 3, 4, whereby the reducing gear ratio can be adjusted.

IPC: G06F11/10
Filed: 1979-08-14
Abstract: PURPOSE: To reduce in-use gate circuits by finding exclusive OR of shifted-out SO data in the opposite direction of number N of all bits of shifted data minus number n of bits of the SO data when n is greater than half N.  
     CONSTITUTION: Input data to be shifted are applied to terminals a 0 Wa 7 , and data of assigned shift extent to terminals b 4 , b 2  and b 1 ; and parity data PD is input to terminal P, and information on the shift direction to terminal D respectively. Decoder 11, when shift extent n is not less than four bits, provides shift extent of 8-minus-n bits. As for the data applied to terminals a 0 Wa 7 , only shifted-out SO bits are led out of NAND gates 13W20 by the output of decoder 11. When the shift direction is right and the shift extent is not less than four bits, gate 21 is opened. NAND gates 24 and 25 are applied with right and left adjacent shift-in bits S 2  and S 1  respectively. In a right shift, SO bits are OR-ELSE-ed by EX OR gate 39 and bit  S 2  and PD are also OR-ELSE-ed, so that the prediction result of the parity of the  shifted cata can be obtained.

Title: Two-layer type liquid crystal display element
Inventor: KIKUCHI NAOKI
IPC: G02F1/1347
Filed: 1990-04-20
Abstract: PURPOSE:To improve a contrast by specifying the product of the liquid crystal layer thickness of the picture element part of a display layer and the refractive index anisotropy of a liquid crystal and the product of the liquid crystal layer thickness of the non-picture element part of the display layer and the refractive index anisotropy of the liquid crystal. CONSTITUTION:The product of the liquid crystal layer thickness d11 of the picture element part of the display layer 1 and the refractive index anisotropy DELTAn1 of the liquid crystal 8 is so set as to be larger than the product of the liquid crystal layer thickness d2 of a color compensating layer 10 and the refractive index anisotropy DELTAn2 of the liquid crystal 15. The product of the liquid crystal layer thickness d12 of the non-picture element part of the display layer 1 and the refractive index anisotropy DELTAn1 of the liquid crystal 8 is so set as to be nearly equal to the product of the liquid crystal layer thickness d2 of the color compensating layer 10 and the refractive index anisotropy DELTAn2 of the liquid crystal 15. Namely, the transmittance is lowest when DELTAn1.d1 and DELTAn2.n2 are equal while no voltages are impressed. The transmittance is low if DELTAn1.d1 is larger than DELTAn2.d2 while a non-selection voltage is held impressed at the time of time division driving. Thus, the transmittances in both the picture element part and the non-picture element part decrease when the non-selection voltage is impressed at the time of time division driving. The contrast of the selected parts increased and the display quality improves.
