Title: Optical flame detector
Inventor: YAMADA KOUJIROU
IPC: F23N5/08
Filed: 1983-08-05
Abstract: PURPOSE:To maintain a high detecting precision against a change in a combustion condition such as a change in load, by a method wherein, based on frequency distribution of a quantity of AC light emitted from flame, ignition and extinguishment are judged. CONSTITUTION:Light, emitted from flame, is guided to an optical sensor part 1 through a light guiding part 2. A band-pass filter part 14 connected to an amplifying part 3 filters only an AC component with a frequency band of 30-50Hz, and a band-pass filter part 15 filters only an AC component with a frequency band of 60-100Hz. A ratio computing part 16 finds a level means value (a) of the frequency band of 30-50Hz and a level mean value (b) of the frequency band of 60-100Hz and computes a ratio b/a between the two level mean values. The computed ratio b/a is inputted to a comparator 11 and is compared with a reference threshold value ratio inputted from a reference generator 12. When the ratio b/a exceeds the reference threshold value ratio, the comparator 11 generates an ON signal, and when it is below the reference threshold value ratio, it generates an OFF signal. A value of 0.4-0.6 is selected the reference threshold value ratio.

Title: Method for measuring inner strain in alumina ceramics material
Inventor: WADA TOSHIAKI
IPC: G01L1/00
Filed: 1982-08-18
Abstract: PURPOSE:To make it possible to measure inner strain without contact and to enhance mass productivity of magnetic heads, by comparing the deviation value computed by a polarization analysis method with the preset reference value of the deviation of a phase difference, and relatively judging the inner strain of a material to be machined. CONSTITUTION:The surface of an alumina ceramics material is precisely abraded to the surface roughness of 50Angstrom  or less. In a polarization analysis method, polarized light is projected on the surface of a sample Sa, and the change in polarized state generated at the time of reflection is observed. The fast axis of a compensator C is inclined by pi/4, and a polarizer P1 and a light detector A1 are rotated together. So called cross Nicol state is obtained, and the light transmitted through the light detector is made to become zero. An azimuth angle (P azimuth) theta of the polarizer at this time is measured. A phase difference DELTA of the sample Sa is obtained by an expression DELTA=pi/2-2theta. An azimuth angle (S azimuth) psi is an observed value, which is required to obtain a reflction coefficient ratio. The phase difference DELTA of the sample obtained by the polarization analysis method is compared with the phase difference DELTA which is set as a reference, and the inner strain of the sample is measured in the direction of the phase.
