Filed: 1985-02-26
Abstract: PURPOSE:To automatically detect the service life of an oxygen meter cell by placing the cell in the atmosphere containing a known amount of oxygen and performing calibration for coinciding the output voltage of an adder with the reference voltage of a comparator. CONSTITUTION:The oxygen meter cell 1 is placed in the air atmosphere, the output voltage V0 is added to an input voltage Vb from a D/A converter 9 and the output voltage V0' is compared with a reference value Vs in a comparator 4. If the voltage V0' is low, an oscillator 6 starts to oscillate and the voltage Vb is increased by the count up of a counter 7 until the voltage V0' is made equal to the reference value Vs for calibration. The calibration is effected for each power turn on and the limit calibration state is judged to the present when the high-order 4 bits of the output of the counter 7 is at the H level. This is displayed on a display part 11. Hence, the service life of the cell is automatically detected by automatic calibration.

Abstract: PURPOSE:To attain high privacy call characteristic with a compratively simple circuit constitution by switching one of an oscillating frequency from a sender side oscillator, the frequency division ratio of a frequency divider, an upper SSB wave and a lower SSB frame at the sending side random and changing over the selection of an oscillating frequency of an oscillator at the reception side, a number of multiple of a multilier, the selection of the upper SSB or lower SSB wave at the reception side. CONSTITUTION:A sound signal having a component of 0.3-3.4kHz fed to a terminal MOD IN is mixed with an output from a sending side oscillator 1-2 at a frequency converter 1-1 in an SSB generating section at the sending side, the result passes through a band pass filter 1-3 and is converted into an SSB wave. The SSB wave passes through an amplitude limiter 2, is subjected to 1/N frequency division by a frequency divider 3 and converted again into a frequency division wave in the sound band. An envelope component of the sound signal is extracted by a detector 4 and used to apply frequency modulation to a subcarrier by a modulator 5. The synthesized wave fed to a terminal DEM IN at the reception side is separated into a frequency division wave and a modulation wave by a low pass filter 6 and a high pass filter 11 in a separation section. After the frequency division wave is subjected to N multiple by a multiplier 7, the result is mixed with the output of the oscillator 9 at the reception side by a frequency converter 8 and converted into the wave of the sound band.

Title: Foamed body
Inventor: YABUSHITA HITOHIRO
IPC: A43B13/04
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To accomplish a lightweight construction, enhance the wet gripping performance and prevent the deterioration with time, by crushing seed shells to have under a specified mean particle size, and mixing the crushed seed shells into a foaming body. SOLUTION: The mean particle size of crushed seed shells is set to to under 1.0 mm. If this foaming body is used in a shoe sole, the structure of the surface 12 is shaved by the road surface in the course of putting on the shoe, and the seed shells 13 enhance the wet gripping property by means of the spike effect. In particular, the seed shells 13 have a low wettability with a matrix 14 of rubber or resin, so that the matrix 14 runs away from the seed shells 13 to cause enlargement of the cell 10. Accordingly the spike effect given by the cell wall 11 around the cell 10 is enhanced. In association with enlargement of cell 10, the water and/or oil contained will easily run into the cell 10, which improves the wet gripping performance.  This effect owing to the cell 10 and cell wall 11 is continuously obtained even after the seed shells 13 have slipped off, so that a stabilized anti-skid characteristic can be expected.

Abstract: PURPOSE:To improve the alignment precision of pattern by a method wherein alignment marks are detected by optically scanning multiple parts of an alignment mark. CONSTITUTION:Different two positions of alignment marks 104A, 104B in X, Y direction are scanned by laser beams. For example, when any one alignment mark is detected to be defective, one signal wave from 108A out of two signals 107A, 108A transmitted from a mark end is disturbed making it impossible to detect a central line 111 in a correct position. In such a case, further different positions are scanned by laser beams to obtain another wave form 108B, a composite mean of normal wave form 108 and disturbed wave form 108A. Resultantly, a middle point 111B between a wave form 108B and another wave form 107B is to recognize the correct position.
