Title: Audio signal reproducing device equipped with noise eliminating circuit
Inventor: WATAYA YOSHIZUMI
IPC: G11B20/24
Filed: 1980-08-25
Abstract: PURPOSE:To reduce noises by shortening a previous-value holding time when the previous value of the output signal of an LPF is held, by changing an input to a previous-value holding circuit over to a signal, which neither passes through the LPF nor has a transient period, during the transient periood of the LPF. CONSTITUTION:An audio FM signal passed through a BPF2 is detected by a dropout detecting circuit 7 and the trailing edge of its dropout detection signal is used as a trigger to operate a monostable multivibrator 16, so that a pulse having pulse width equivalent to the short transient period of a signal delay circuit 14 is outputted. Then, an OR circuit 9 is operated to operate a previous-value holding circuit, and the trailing edge of the output signal of an OR circuit 12 is used as a  trigger to operate a monostable multivibrator 18, thereby generating and outputting  a pulse reading the trailing edge of the long transient period of an LPF5 to an OR  circuit 19. Consequently, the input side of the circuit 6 is changed over to the side  of a signal delay circuit 14 in the very short transient period of the BPF2 only during the period when the transient phenomenon of the LPF5 attenuates, so the previous- value holding period is shortened to reduce noises due to dropouts.

Filed: 1992-05-08
Abstract: PURPOSE:To obtain an optical fiber having excellent optical transmitting property and high efficiency by adding Dy ions to an optical material in high optical refractive area of an optical fiber having a high light refraction area and a low light refraction area each having a prescribed refractive index difference and capable of transmitting an optical signal in a specific wavelength area in a single mode. CONSTITUTION:The object optical fiber has a high optical transmitting property and a low optical transmitting property (0.01-1% refractive index), and transmits an optical signal of 800-1400nm wavelength area in a single mode. This optical fiber is obtained by adding 100-10000ppm divalent Dy (dysprosium) ions to an optical material (e.g. fluoride based or SiO2 based material) in the high optical refractive area. The figure shows energy level of a Dy ion and when an excited light having 830nm wavelength enters the optical fiber, an energy level of the Dy ion is transferred to absorption excitation level 105 and then transferred to a semistable excitation level 103 by a non-luminescence transition 121 by phonon release. Then, a light having 1.25-1.35nm wavelength is released and returned to a base level 102.

Title: Dry ashing apparatus
Inventor: YANO HIROSHI
IPC: H01L21/302
Filed: 1986-05-20
Abstract: PURPOSE:To largely suppress an etching with fluorine radical on a base part without so decelerating an ashing velocity by switching gas fed into a plasma light emitting chamber from a mixture gas of CF4 and O2 to only oxygen when the intensity of a light emitting spectrum of a specific wavelength becomes a preset predetermined value or higher. CONSTITUTION:When a resist is ashed by an oxygen radical, a CO light emitting spectrum is generated. Then, a spectrochemical analyzer 17 detects only the intensity of the CO light emitting spectrum, and outputs a detection signal of a level responsive to the detecting intensity. When the intensity of the input detection signal spectrum arrives at a predetermined value, a comparator 18 supplies a control signal of a logic level different from that supplied so far since the input detection signal level becomes a first reference signal level or lower from an input terminal 19 to close a conduit 10 by a solenoid valve 11. Thus, the input of Freon gas (CF4) to a plasma light emitting chamber 6 is stopped, but only oxygen (O2) is fed into the chamber 6 to eliminate an etching with fluorine radical (F*) on the base of a sample 14.

IPC: G02B23/06
Filed: 1985-06-01
Abstract: PURPOSE:To suppress the movement of an ocular due to eye pressure small by making a focus adjustment through the combination of a cam mechanism and a screw mechanism. CONSTITUTION:When a blade piece 10B is pressed, a focus adjusting cylinder 10 rotates and a pin 9C engaging an oblong hole 10A rotates on a plane perpendicular to an optical axis according to said rotation. In this case, the pin 9C engages a slanting cam hole 9B formed in a body 9 which is inhibited from rotating, so the pin 9C moves in the direction of the optical axis along the slanting cam hole 9B, os it moves up in the oblong hole 10A as well. Then, a rod body 8 to which the pin 9C is fitted rotates perpendicular to the optical axis while moving up in the direction of the optical axis similarly. Consequently, the ocular coupling with the cylinder body 7 moves forth in the optical-axis direction by the sum of the length of said upward movement in the optical-axis direction and the length of the upward movement in the optical-axis direction owing to the rotation of the cylinder body 7 by the rotation of the rod body 8.
