Abstract: PURPOSE:To accurately detect a flaw, in such a case that non-flaw signal levels of a definite length or less is intermittently generated between flaw signal levels in a flaw inspecting apparatus of a reproduction signal, by interpolating said non-flaw signal levels as a series of flaw signals. CONSTITUTION:A flaw detecting part 102 detects the abnormal part of a reproduction signal to output a flaw judging signal which is, in turn, inputted to the inverter 104 and shift register 105 constituting a flaw judging signal interpolating part 3. The clock of the shift register 105 is supplied from a clock generating circuit 106 and each of the register outputs of the shift register 105 is inputted to a multi-input AND gate 107. The output of the gate 107 and that of the final stage of the register 105 control an RSFF 108. In this constitution, when the length between non-flaw signal levels appearing between flaw signal levels is within the number of the stages of the register 105, the output of the RSFF 108 is held to a high level state showing a flaw. That is, the output of the RSFF 108 is outputted to a terminal 109 as an interpolated flaw judging signal.

Title: Device for monitoring temperature stress
Inventor: SHIMOZONO NAOTO
IPC: G01D21/00
Filed: 1981-07-31
Abstract: PURPOSE:To obtain total operation hours which are conerted into the total operating hours of the device under a preset temperature, by changing the counting speed in response to the difference between an environmental temperature and the preset temperature, and monitoring the temperature stress of the device even under the state of the variable environmental temperature. CONSTITUTION:The output of a temperature sensor 1 is linearized 2 and compared 3 with a preset voltage e(TO) corresponding to a reference temperature TO. The output voltage corresponding to the difference is fed to an exponential amplifier 4, thereafter converted into a frequency by a V-F converter 5, and inputted to a counter 6. When the environmental temperature T is larger than the preset temperature TO, the counter 6 expedites the counting. When T is smaller, the counting is delayed. Therefore, even though the environmental temperature is changed into any values, the hours corresponding to the case, wherein the operating hours of the devices are assumed to have been elapsed under the preset environment, can be found.

IPC: G01B7/34
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a properly automatically surface engageable scanning force microscope. SOLUTION: A vibration probe 18 of a scanning force microscope is engaged with a sample surface 24 in an initial approach process. In this process, the probe is moved to the sample surface, until the amplitude of probe vibration in excitation frequency receives effect slightly by the force between a tip and a sample. Next, the change in the vibration amplitude generated by the dithering vibration superposed on excitation vibration is engaged in a final approach process which exceeds a predetermined threshold limit. The excitation frequency is reduced when the phase angle of vibration exceeds other limit, and the amplitude of the excitation vibration increases when amplitude or tip vibration becomes a set value or less. During approach and scanning, vibration amplitude is measured by a demodulator having an intermediate reference signal which is locked in phase by a tip motion signal.
