Patent JP-S5991503-A (JP)
Title: Control amplifier
Inventor: KUROSAWA RIYOUICHI
IPC: G05B11/36
Filed: 1982-11-18
Abstract: PURPOSE:To control the input of a controlled system by adding a quantity obtained by integrating a deviation value between an instructed value and a detected value to a quantity proportional to the deviation value to obtain a proportional integral value and outputting a value obtained by subtracting a compensating value proportional to the detected value from this proportional integral value. CONSTITUTION:A deviation value X1 between an instructed value ni and a feedback value n0 is obtained by subtraction. This deviation value X1 is inputted to a proportinal integral amplifier 12. First, the deviation value X1 and a constant Kp are multiplied to obtain a proportional component X2, and next, the deviation value X1 is divided by a value (for example, 1,000) corresponding to a sampling period to obtain a value X3. This value ismultiplied by a constant KI to obtain an integral quantity X4 per one sampling. The quantity X4 is added to the preceding integrated value to obtain a new integral value X5 as an integral component. The integral component and the proportional component are added to obtain a proportional integral value X6. Meanwhile, the feedback value n0 is inputted to a proportional amplifier 13 and is multiplied by a constant KB to obtain an overshoot preventing compensating value X7, and these values are subtracted in a subtractor 14 to obtain an output eC of a control amplifier 10.

Filed: 1987-08-12
Abstract: PURPOSE:To make an automatic transmission small and light by carrying out selecting and shifting operations for engaging shift levers with the recessed parts of shift fork shafts by means of two sets of simultaneously rotating rotary cams. CONSTITUTION:Two sets of rotary cams C1, C2 are both fixed to a shaft 14 and normally/reversely rotated by means of a single actuator.

Title: Eye examination device
Inventor: HAYASHI AKIHIRO
IPC: A61B3/028
Filed: 1991-07-15
Abstract: PURPOSE:To enable a subject to take a look at a traget at a stable attitude even if the subject is changed in height by detecting the position of an examined eye, and concurrently driving a reflective optical equipment member based on the result of the detection. CONSTITUTION:The position of an eye examination table in height can be known based on a resistance value indicated by a potentiometer 20. A potentiomenter 25 detects a resistance value equivalent to the quantity of movement of a potentiometer moving shaft 26. Based on the result of the detection of the potentiometers 20 and 25, a microcomputer circuit computes a distance from a self-consciousness eye examination unit (measuring window) 3 to a reference surface (for example, the installation surface of the eye examination table). Based on the computed distance, a signal is sent to a pulse motor driver to drive the pulse motor 9, so that a mirror 7 is thereby rotated by a specified angle. Thus, since the mirror is automatically driven, eyesight test can be smoothly carried out.
