Title: Peak shift measuring method for magnetic head
Inventor: HASEGAWA YUJI
IPC: G11B5/09
Filed: 1989-12-29
Abstract: PURPOSE:To easily measure the peak shift by converting each pulse generated by binarization into a single pulse which is longer than the time corresponding to one bit of a test pattern and is shorter than the time corresponding to two periods of the test pattern and is synchronized with the test pattern and using a signal obtained by this conversion as the gate signal. CONSTITUTION:The reproduced signal from a magnetic head is binarized by a level in a certain signal level range other than OV, and each pulse generated by this binarization is converted into a single pulse which is longer than the time corresponding to one bit of the test pattern and is shorter than the time corresponding to two periods of the test pattern and is synchronized with the test pattern, and the signal obtained in this manner is used as the gate signal and masks the signal obtained by binarizing the reproduced signal with OV to obtain a signal to be measured. That is, a pulse width and a pulse period are easily obtained by proper pulse width adjustment and delay because the gate signal is the single pulse synchronized with the period of the test pattern. Since the position of the test pattern is distinguished to measure arbitrary pulse width and pulse period in this manner, peak shift measurement including position information of the test pattern is simplified.

Title: Exhaust control method for regenerative burner combustion system
Inventor: TAKAHASHI YASUHIRO
IPC: C21D1/52
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide an exhaust control method of a regenerative burner system which enables purging in a short time. SOLUTION: In an exhaust control method of a regenerative burner combustion system having a burner and a heat storage device, in the switching of a combustion side burner to the discharge of a combustion exhaust gas from the combustion, a combustion air path is closed to perform a prepurging of a fuel left in a burner body by combustion air and then, an exhaust path is opened. In switching an exhaust side burner to combustion from the discharge of the combustion exhaust gas, an exhaust system is closed to perform a post purging of the exhaust gas left in the burner body by the combustion air and then, the combustion air path is opened. Thus, the combustion gas and the combustion exhaust gas can be pushed out into a furnace by the combustion air for purging.  The combustion air will not flow directly into the exhaust path thereby eliminating back fire in the exhaust path or delay in the combustion of the fuel otherwise caused by blocking by the combustion exhaust gas.
