Title: Gas flow rate controller
Inventor: OTA RYUSUKE
IPC: G05D7/06
Filed: 1990-01-17
Abstract: PURPOSE:To immediately catch malfunction owing to the contamination of gas and to prevent damage by providing a first flow rate sensor and a second flow rate sensor. CONSTITUTION:A first sensor tube 1a and a second sensor tube 2a have thermoregisters, and they constitute a part of the bridge circuits of detection circuits 1b and 2b, whereby an output voltage proportional to a gas flow rate is transmitted to amplifier circuits 1c and 2c. A comparison circuit 4 compares the output voltage from the first flow rate sensor 1 and that from the second flow rate sensor 2 and operates an alarm 5 when the difference exceeds an abnormal value which is previously set. Since a probability that the sensors 1 and 2 simultaneously generate clogging and the flow of gas is deteriorated is considerably small, the occurrence of clogging can securely be learnt. Even if there is the clogging of the sensor tubes owing to the contamination and the like, it can immediately be caught and coping with the situation is attained, whereby damage can be avoided.

Title: Thermal asperity detector
Inventor: BURATSUDORI KEI DEIBUISU
IPC: G11B5/39
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To detect the thermal asperity(TA) of a disk drive system. SOLUTION: The fluctuation signals included in the signals read from a double stripe magnetic reluctance head(DSMR) 50 having a pair of reading head parts are removed by a differential amplifier 68. The fluctuation signals are generated from the TA and appear as common-mode signals. The TA components included in the signals are drastically attenuated by the characteristic of the common-mode removal of the differential amplifier 68. A TA detecting circuit 56 receives the signals read from the respective head parts via conductors 58, 59, averages these signals and filters the signals by a high-pass filter; thereafter the TA is detected by a window comparator 92. A counter 62 counts the number of the occurrence of the TA and a head danger detecting circuit 66 generates a trigger signal, thereby making it possible to operate an external diagnostic device 63, etc., in real time.
