Title: Magnetic head for measuring head characteristic
Inventor: FUKUMOTO YASUSHI
IPC: G11B5/39
Filed: 1994-07-14
Abstract: PURPOSE:To make it possible to measure the head characteristics of an MR head in a wafer state by providing this MR head with a pseudo head for inputting the magnetic signal for measuring the head characteristics of the MR head to an MR element at a prescribed distance in front of the MR element. CONSTITUTION:Signals of arbitrary waveforms for reproducing the signals from a magnetic recording medium are first passed to a conductor coil 16 of the pseudo head 3. Magnetic signals are then outputted from the pseudo head 3. The outputted magnetic signals enter the MR element 8 from the gap part of the MR head 2. The output is obtd. from the magnetic signals entering the element 8 and this MR head output is taken out of a front end electrode 6 and a rear end electrode 7. The evaluation of the electromagnetic conversion characteristics of the MR head 2 in the wafer state before a finished product is made possible by measuring the MR head output in such a manner. More particularly, the opposite distance L between the MR head 2 and the pseudo head 3 is set approximately the same as the actual opposite distance between the magnetic head and the medium and, therefore, the characteristics of the head 2 are evaluated in the state approximate to the actual state.

Title: Combustion control apparatus
Inventor: UEKI KOUICHI
IPC: F23N5/00
Filed: 1980-11-17
Abstract: PURPOSE:To prevent abnormal combustion such as oxygen shortage combustion or backfire  combustion by a method wherein the combustion control apparatus is provided in a liquid fuel  combustion apparatus so that when a detecting signal from a flame detecting means is below a predetermined value, the combustion of the fuel is stopped due to the interruption of the supply of electric current to a wick holding means and an alarm signal is generated. CONSTITUTION:In case where the liquid fuel combustion apparatus is operated for a prolonged  period of time within a closed chamber and the quantity of carbon monoxide increase rapidly  due to a shortage of oxygen, the flame detecting means 26 detects such abnormal combustion  as a variation of ion current and when the output voltage across resistors 36 and 37 decreases  beyond a reference potential determined by resistors 41, 42 and 43, the output of a comparatur  47 goes LOW to open a relay contact 64a so that the wick holding means 3 can not hold a  wick at its combustion position and the wick is lowered to extinguish fire thereon. Simultaneously with the above operation, the cathode potential of a diode 63 increases to cause a transistor 68 to become conductive through a resistor 64 and a diode 65 and a buzzer 69 is excited  to give an alarm indicating that the combustion is stopped. Further, even in case where a  backfire phenomenon takes place due to a rush of wind and a flame spreads to a tank side  wick, the supply of electric current to the wick holding means 3 is stopped to thereby extinguish fire.

Abstract: PURPOSE:To allow the driving start and driving stop of a sense amplifier at adequate timing by detecting the rise of a word line driving signal by a (p) channel MOS transistor and the fall thereof by an (n) channel MOS TR. CONSTITUTION:The rise of the word line driving signal Sw inputted to a pseudo word line 1 is detected via the (p) channel MOS TR Qp turned on by a 1st potential and the fall of the word line driving signal Sw inputted to the pseudo word line 1 is detected via the (n) channel MOS TR Qn turned on by a 2nd potential, by which the sense amplifier driving signal is obtd. The potentials different from each other of the respective MOS TRs Qp, Qn are, therefore, applied as reference voltages for comparison. Both of the rise and fall of the word line driving signal Sw are adequately and exactly detected in this way. The execution of both of the driving start and driving stop of the sense amplifier at the adequate timing is possible in this way.

Title: Amplitude level correcting device for video signal
Inventor: HANEDA YOSHIHITO
IPC: H04N5/52
Filed: 1992-06-22
Abstract: PURPOSE:To uniform the amplitude levels of all video signals from respective signal sources to a fixed level when these levels are mutually different in an image circuit for switching and selecting plural video signals outputted from respectively different signal sources and processing a selected signal. CONSTITUTION:A video signal selected by a switching circuit 1 is inputted to an image amplifier 2. A synchronizing signal level detecting part 3 detects a synchronizing signal amplitude level in a vertical blanking interval from an output signal of the amplifier 2. A comparator 4 sets up the output level (e.g. 1Vpp at 75OMEGA terminal) of the amplifier 2 and sets up DC voltage corresponding to the amplitude of a synchronizing signal corresponding to the set level as a reference voltage Vs. The comparator 4 compares the detected synchronizing signal amplitude level with the reference voltage Vs and controls the gain of the amplifier 2 based upon the comparing result. Consequently the output of the amplifier 2 is uniformed to the fixed level.
