Patent JP-H1127115-A (JP)
Title: Threshold signal generating circuit and digital signal recovery circuit provided with the generating circuit
Inventor: IDE SATOSHI
IPC: H03K5/08
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To suppress noise in a non-signal state over a wide dynamic range of an input signal in the digital signal recovery circuit consisting of a voltage division circuit that generates a threshold signal level resulting from a prescribed voltage division of an output of a bottom detection circuit and an output of a maximum value detection circuit. SOLUTION: In a state of a non-signal input, an output PD of a peak detection circuit and an output BD of a bottom detection circuit are equal to each other as a reset state of the circuit from the standpoint of the input signal state. However, since an output LS of a level shift circuit is set higher than the output BD by a prescribed level, the output LS is higher than the output PD, and then the output LS is selected as a maximum level detection signal MX and a threshold signal level TH is higher than the output BD by, e.g. LS/2. Noise in a non-signal state is suppressed by selecting the level LS/2 to be sufficiently higher than a peak level of the noise. In the case of the input state receiving a positive pulse signal, the output PD is higher than the output LS.  Thus, the output PD is selected as the maximum level detection signal MX, and the threshold signal level TH is higher than the output BD by a level PD/2, which is a half of the input level.

Title: Manufacture of micro fresnel lens
Inventor: NIRIKI TAKASHI
IPC: G02B5/18
Filed: 1985-08-20
Abstract: PURPOSE:To improve lens characteristics by varying the quantity or range exposure of resist according to gamma characteristics of the resist and approximating the shape of the stepwise saw-tooth waves of the remaining film of the resist to the ideal curve of a micro Fresnel lens. CONSTITUTION:A figure (a) shows variation in the thickness of the remaining film with the quantity of exposure of the resist and a curve in a figure (b) varies the range of exposure, so its gamma characteristics are used as they are. Then, 13-18 of the same exposure are projected on this curve and shifted onto the phase shift function psi(gamma) of an ideal curve in a figure (c) to determine the exposure range of each time in a radius-(gamma) direction. At this time, the thickness of the remaining film remains according to longitudinal axes 25-30, but the exposure range in the radius-(gamma) direction is corrected by the gamma characteristic curve in the figure (b) as to the phase shift function psi(gamma), so the shape of stepwise saw-tooth waves of the remaining resist film which is formed actually conforms to the phase shift function psi(gamma) of the ideal curve in a figure (d). Consequently, lens characteristics such as primary efficiency of convergence and a beam spot diameter are improved.
