Title: Measurement for deep level in semiconductor
Inventor: SHIBATA JIRO
IPC: G01N21/00
Filed: 1986-05-21
Abstract: PURPOSE:To enable a reduced measuring time in the measurement of deep level, by irradiating a sample with a specified another single wavelength recoverable as light at each light irradiation or in a specified wavelength area before the sequential irradiation with main light. CONSTITUTION:Electrons having existed at a filled band 1 is excited to a deep level 3 and ionized by light irradiation with light energy 4 and appears as photocapacitance at the same time, with the ionization, this deep level 3 moves coordinates into the meta stabilized state 6. Therefore, even when a current flows due to initialization of the filled band, the excited electrons can not return to ground state and hence, photocapacitance remains unchanged but when light exceeding the light energy 5 is directed, the excited electrons are released to conduction band and the photocapacitance is recovered. This can reduce measuring time in the measurement of deep level in a semiconductor.

Title: Detecting method of position of boundary
Inventor: HATA JUNICHI
IPC: G06T1/00
Filed: 1990-05-07
Abstract: PURPOSE:To detect a stable position by sequentially differentiating a dark-and- bright image from outside to inside of the boundary or from inside to outside, and setting a point where the differentiated value is an absolute value not smaller than a set value and an extreme value as a boundary point. CONSTITUTION:A dark-and-bright image obtained by photographing an object having a boundary is sequentially differentiated in a direction advancing from outside to inside of the boundary or from inside to outside of the boundary. A point where the differentiated value has an absolute value not smaller than a set value and an extreme value is rendered a boundary point. For instance, when an electrode is present in a circuit board, a crossing point between an (x) axis and the electrode is obtained. After setting a starting point A and an end point B, the distribution of luminance between the starting point A and the end point B is obtained as indicated by a solid line 1, and the luminance is differentiated in the AB direction. When extreme values not smaller than an absolute value set by a broken line are picked up, P' is obtained as a boundary point. Even if the luminance is changed as shown by 2 or 3, the position of the point P, is not changed easily.

Title: Bidirectional and simultaneous communication equipment
Inventor: FUNO KENJI
IPC: H04B3/20
Filed: 1984-06-08
Abstract: PURPOSE:To stop the ringing tones without deteriorating the sound quality by providing a step changing device for call signal at the transmission or reception side of a bidirectional and simultaneous communication equipment using a microphone and a speaker. CONSTITUTION:The signal sent from a microphone 10 is amplified 11 and delivered to a talking circuit 17 via a buffer amplifier 12. The signal deteriorated by the circuit 17 is equalized by an equalizer 13. Then the equalized signal is amplified by a power amplifier 14 for drive of a speaker 15. A ringing tone stopping device 16 is provided at a part of the reception side of a bidirectional and simultaneous communication device. The device 16 increases or decreases the step of the signal supplied from the device 16 by such a degree, e.g., half octave or so that causes no change of the sound quality. Thus the phase of an output signal is completely different from that of an input signal. Therefore no acoustic connection is produced between the microphone 10 and the speaker 15. This eliminates a positive feedback loop and prevents the generation of ringing tones.
