Patent JP-S5573935-A (JP)
Title: Optical information reader
Inventor: TANAKA YOSHIHARU
IPC: G02B7/28
Filed: 1978-11-20
Abstract: PURPOSE:To exercise accurate focus control by driving a focusing lens by correcting a difference between outputs from two photo detection parts into a linear output by using a nonlinear amplifier. CONSTITUTION:When beam spots stay in the centers of photo detection surfaces 5a and 5b of photoelectric element 5, focuses agree each other. Once focuses deviate each other, difference power V from photoelectric element 5 shows a curve which passes through origin O. In case that V would lose its linearity near orign O, depressing switch S1 when difference output V is found positive by comparator C1 allows amplifier A1 to output difference output V amplified (n1) times and when the difference output is negative, switch S2 is turned on to generate difference output V amplified (n2) times by amplifier A2, so that difference output V will nearly be linear by a difference between amplification degrees (n1) and (n2). In this way, the output of non-linear amplifier 7 is inputted to focusing lens driver 8 to move focusing lens 2 toward light axis P, so that accurate focusing control can be exercised.

Abstract: PURPOSE:To decrease the kinds of components of a device in number and to make production control advantageous by providing one magnetic sensor with plural sensor element groups which differ in array pitch according to resolution and providing connection terminals to the respective sensor element groups individually. CONSTITUTION:For example, when the magnetic sensor 1 provided with an element group of sensor elements 2 with array pitch P' and an element group with array pitch P is used in combination with a magnetic drum having magnetization pitch 4P', connecting terminals 3 of the element group with the array pitch P' are connected to a waveform shaping circuit 6 and when the sensor is used in combination with a magnetic drum with magnetization pitch 4P, connecting terminals of the element group with the array pitch P are used similarly. Consequently, the kinds of components are decreased in number at the time of the mass-production of an encoder with different resolution, thereby improving the production control.

Title: Eliminating circuit of impulsive noise
Inventor: FUJISHIMA YUKITOMI
IPC: H03G3/34
Filed: 1982-08-23
Abstract: PURPOSE:To eliminate the impulsive noises without generating signal distortions, by excluding a period including the impulsive noises of an input signal and then interpolating the excluded period with signal levels before and after the excluded period. CONSTITUTION:The gate pulse given from a detecting circuit (not shown in the figure) which detects the impulsive noises controls switches S1-S4. When no impulsive noise exists, an input signal (f) is delivered via a delay circuit 12 having the same time as the gate pulse width, a buffer amplifier 17 and the switch S1. If the input signal contains impulsive noises, the gate pulse turns off the switches S1 and S3 to prevent the output of the signal (f) to an output terminal 18 for a signal period containing the impulsive noises and holds the difference of signal levels before and after a gate pulse period at a capacitor C2. At the same time, the switches S4 and S2 are turned on, and an interpolation circuit consisting of an arithmetic amplifier 14 and a buffer amplifier 15 charges and discharges the signal held at the capacitor C2 to a capacitor C1 and then delivers the interpolated signal to the terminal 18. The switch S2 and a buffer amplifier 16 smooth the joint of signals after the end of interpolation.
