Title: Flow rate controller
Inventor: NAGANO OSAMU
IPC: G05D7/06
Filed: 1984-05-30
Abstract: PURPOSE:To eliminate the variation of the total flow rate during a valve switching action for a flow rate control system using master and slave valves, by providing a function generator into a control system of each valve to convert a command input signal for control of valve opening amount into a command signal to secure a flow rate proportional to said input signal. CONSTITUTION:A master valve 7 and a slave valve 8 are provided at a main flow path and a bypass flow path respectively. At the time of switching of each valve, the signals set by setters 1 and 2 for valve open/close speed are supplied to integrators 3 and 4. Then the valve opening amounts are indicated by switches 5 and 6 via function generators 9 and 10. A nonlinear relation is secured between the valve opening amount and the flow rate. In this respect, the generators 9 and 10 deliver command signals after conversion so that the valve flow rate has a linear change to the input signal that commands the valve opening amount. The flow rate of each flow path has a linear change in proportion to the opening amount setting command signal value of each valve. Thus the total flow rate is kept at a constant level of switching both valves with the total value of both opening amount setting command signals kept at a constant level.

Filed: 1983-06-17
Abstract: PURPOSE:To realize uniformed reading accuracy by providing a pattern in a way that a part in bits is divided into two by an electrode forming material to form a low resistance part in the bit in the stage of electrode formation thereby decreasing the probability of mis-reading of a minute wire. CONSTITUTION:An intermediate electrode pattern of a low resistance equivalent to an aggregation is provided intensionally in the bit. The intermediate electrode, i.e., a minute wire pattern 15 is formed actually with the same material as that forming both electrodes at the selection side of a group side and divides a part in the bit into two. Then the distance between the electrodes is set equal to or slightly smaller than the sub-scanning line width. Fig. (a) shows the state without any aggregation, Figs. b, c, d indicate the state where the aggregation 14 exists. Since the minute wire pattern 15 is provided in the bit shown in Fig. (a), a high resistance ratio is avoided. Since each bit shown Figs. c, d includes all the aggregation, the part does not contribute to the photoelectric conversion but rather to the low resistance ratio and the suppression of variance in the resistance value distribution.

Abstract: PURPOSE:To maintain concentricity, and to shorten measuring time by constituting so that two sets of machine tools having been arranged so as to be opposite to each other automatically measure the positions of detectors respectively, and that a workpiece is machined by making these positions a reference. CONSTITUTION:The sets of machine tools 10, 11 are arranged in such a way that respective main spindles 10a, 11a are opposite to each other, and to a floor plate 13 on which a workpiece 12 is installed, detectors 14, 14 are arranged, and it is so constituted that the two sets of machine tools 10, 11 automatically measure the positions of the detectors 14, 14 respectively, and carry out working by making these positions a reference. As a result, even if the level change and temperature change of machine tools 10, 11 are caused, since the detection is carried out in the immediate neighborhood of the working position, concentricity can be maintained. Furthermore, the measurement is automatized, so that the measuring time can be shortened. And, by adding this system to a compound machine tool, both the concentricity requiring working and the non-requiring working can be simultaneously and continuously carried out by two opposite machines.
