Patent JP-H05160646-A (JP)
Title: Optical receiver
Inventor: SAKURA NARIYUKI
IPC: H04B10/60
Filed: 1991-12-10
Abstract: PURPOSE:To reduce a noise current and the bias variance of input together by allowing only the resistance value of a second resistance as a feedback resistance to take part in determination of an input converted noise current and an input DC potential. CONSTITUTION:A resistance value RL of a load resistance 9 and a resistance value RF of a feedback resistance 10 are set to satisfy RF>>RL. In this case, an input converted noise current iN[A/HZ<1/2>] is expressed by a formula I. The noise is reduced by the bias resistance value in accordance with this formula, and a minimum reception power is obtained in the good state. An input DC potential VG at an input terminal 3 of an amplifier 2 is expressed by a formula II where I is the DC component of a photocurrent obtained by a photodetector 1. When a resistance value RF in the formula II is set to 20KOMEGA, the ratio of the resistance R to the bias resistance value is 1/5. That is, variance of the bias potential in the amplifier 2 is considerably relaxed even when a photocurrent is increased, and the maximum reception power is obtained in the good state. Consequently, the minimum and the maximum reception powers are obtained together in the optimum state.

Title: Liquid crystal display device
Inventor: NAKAMURA KIMIAKI
IPC: G02F1/1337
Filed: 1990-11-28
Abstract: PURPOSE:To obviate the generation of a display inversion, etc., even when gradation display is executed by disposing a linear phase element between two sheets of polarizing plates in such a manner that its phase delay axis parallels or intersects orthogonally with the absorption axes of the polarizing plates. CONSTITUTION:The linear phase element 7 which has the phase delay axis 7a in a prescribed direction and applies a phase difference to incident light are so disposed between two sheets of the polarizing plates 3 and 5 that the phase delay axis 7a parallels or intersects orthogonally with the absorption axes 3a, 5a of the polarizing plates 3, 5. Namely, the phase delay axis or phase advance axis of the linear phase element 7 is set along the absorption axes 3a, 5a of the polarizing plates 3, 5 so that the axis of polarization of the light transmitted through a liquid crystal is prevented from passing by the absorption axis 5a of the polarizing plate 5 by the apparent change in the optical axis when viewed from diagonally. The inversion of the transmittance generated in a certain direction at the time of the gradation display is decreased in this way.
