Title: Device for pre-twisting wire material
Inventor: SHIMAZU MASAAKI
IPC: H01B5/10
Filed: 1990-11-22
Abstract: PURPOSE:To remove defective wire material before being twisted by judging the abnormal state of twisting process in the pre-twisting stage of the wire material. CONSTITUTION:A pulse produced at every turn of takeup side cradle 24 is inputted to a magnetizing portion 21. The magnetizing portion 21 receiving the pulse magnetizes a wire material 4 at every turn of the cradle 24. A detection coil 17 detects the magnetized position of the wire material 4 magnetized as described above. If the twisting pitch becomes longer or shorter by any cause, the passing period of the magnetized positions produces difference relative to a reference time. If such a difference is produced, an anomaly judging section 23 sounds an alarm bell, or displays the anomaly to inform an attendant of the anomaly. In this way, abnormal wire material in the twisting process is removed before being fed to a succeeding twisting process to prevent rejects from being produced in the twisting process.

Title: Gas leakage alarm
Inventor: NAGATA SATOSHI
IPC: G08B21/00
Filed: 1989-12-12
Abstract: PURPOSE:To prevent the extension of the delay time and to discriminate even miscellaneous gas by giving an alarm by relatively-short time detection at the time of gas leakage and giving the alarm with relatively long-time detection at the time of leakage of miscellaneous gas whose increase per prescribed time is generally larger than a prescribed value. CONSTITUTION:A level detecting means 2 detects that the level of a voltage signal which is outputted from a sensor circuit 1 and corresponds to the gas concentration exceeds a level corresponding to an alarm point, and a first driving signal generating means 4a generates a driving signal when detection continues for a first prescribed time. If a level change detecting means 4b detects that the increase per second prescribed time of the level of the voltage signal from the sensor circuit 1 exceeds a prescribed value, a second driving signal generating means 4c generates the driving signal and a reporting means 5 gives the alarm only when detection of the level detecting means 2 continues for a third prescribed time longer than the first prescribed time. Thus, the delay time is not extended, and miscellaneous gas staying for a relatively long time is discriminated to surely give the alarm.

Abstract: PURPOSE:To always binarize the bright/dark signal with high accuracy by setting the slice level at the value closer to the dark signal based on the bright/ dark signal obtained from a bright/dark pattern and binarizing the bright/dark signal. CONSTITUTION:A peak value detecting means 6 which detects and holds the peak value of the bright/dark signal, an inverting means 7 which inverts the output signal of the means 6, and a comparison means 5 which compares the output signal of the means 7 with the bright/dark signal to output a binarized signal are provided. Then the means 6 detects and holds the peak value of the bright/dark signal obtained by reading a bright/dark pattern displayed on a paper sheet or the like, etc., to obtain a signal which envelopes the peak value of the bright/dark signal. Then the bright/dark signal is sliced with the signal obtained by inverting the enveloping signal defined as a slice level. Thus the bright/dark signal is binarized. In such a way, the bright/dark signal can be accurately binarized even though the bright/dark pattern is soiled.
