Patent JP-H04247705-A (JP)
Title: Integrated circuit device for voltage comparison
Inventor: TAKAHASHI KAZUKIYO
IPC: H03F3/34
Filed: 1991-02-04
Abstract: PURPOSE:To prevent the resolution from being degraded by providing a first switch group leading the same potential reference voltage for the two inputs in the differential amplifier of the voltage comparison integrated circuit device and a second switch group leading the comparison symmetrical reference voltage. CONSTITUTION:Vin and VR1 are inputted in the noninverted input terminal of the differential amplifier DIF via switches S5 and S6, respectively. VR1 is inputted in the inverted input terminal via switches S7 and S8. In the standby period when the signal is in a high level, the switches S6, S8, S3, S4 closes and in the operation period when the inverted signal is in a high level, the switches S5 and S7 closes. Namely, in the both standby/operation periods, the number of switches passed when the signal is inputted in each input terminal is same. Therefore, if the impedances for these switches are set to the same condition, the resolution can be prevented from being degrated because the noise voltage by switches is inputted in the two input terminals symmetrically.

Filed: 1986-01-24
Abstract: PURPOSE:To evade error occurrence at the time of data transmission by detecting and sending a tip-ring voltage to a center side from a terminal, and detecting variation in the tip-ring voltage at the center side. CONSTITUTION:When the center side needs to know the tip-ring voltage of the terminal equipment, the center side sends a command 'tip-ring input and transmission' and the CPU 8 of the terminal equipment interrupts a data communication between the both on receiving the command and holds the voltage of a port A10 at '0', thereby turning off a relay 3. In this state, the chip-ring voltage is measured and its contents are stored. The data pattern (A1-A6) when the input level of a port A11 varies from '0' to '1' is the switching pattern of the tip-ring voltage. The CPU 8 holds the port A10 at '1' after said measuring operation to turn on the relay 3 and allows the data communication between the terminal equipment and a center computer, and the data pattern (A1-A6) is outputted from a port A7 in series and sent to the center from tip and ring terminals 1 and 2 through a modem 9 and a filter 10.

Abstract: PURPOSE: To provide a method and an apparatus for the continuous crimping of a thermoplastic thread, preventing the deterioration of the quality of a plug and the increase of production loss due to the unstable state of the plug. CONSTITUTION: When a thread F produced from a thermoplastic material is crimped, the yarn is heated with a delivery medium M in a delivery channel 10 and then carried into a stuffer box 2 through an orifice 11. The thread is formed into a plug P. In order to maintain the plug formation constant, the orifice area is monitored in a sensory manner, and the measured signals are used for monitoring purposes as a measured quantity in a control loop, in which the supply of damming back medium S, the conveying away speed vP of the plug, and the supply of a delivery medium are used as manipulated variables. The measuring signals produced by monitoring can be compared with thresholds to produce control signals corresponding to the comparison result for activating alarm, warning or stopping elements. Thereby, the irregular formation (especially blow-out) of the plug can be prevented.
