Title: Am radio receiver
Inventor: HIKITA JIYUNICHI
IPC: H04B1/16
Filed: 1983-08-23
Abstract: PURPOSE:To make normal AGC operation possible even when a strong input exists, by making the load of a frequency mixer circuit adjustable in accordance with an input signal level. CONSTITUTION:When a received AM signal is fed to input terminals 16A and 16B, transistors 10 and 12 are alternately switched in response to the amplitude level of the signal and frequencies of the summed and difference components between a received frequency and a local frequency are formed in a mixer output. The difference component (intermediate frequncy) is fetched from a coil 30s and an AGC voltage VAGC is obtained. When the AGC voltage VAGC rises, a transistor has an electric current absobing capacity corresponding to the voltage rise. As a result, diodes 36 and 38 are conducted and impedances of the diodes 36 and 38 drop to values corresponding to electric currents I1 and I2, and then, the impedance of an intermediate frequency tuning coil 30 is reduced. Consequently, gain suppression due to the current area and load area of a frequency mixer takes place at the same time and the normal operation of AGC is secured.

Title: Magneto-optical recording medium
Inventor: NAKADA MASABUMI
IPC: G11B11/10
Filed: 1989-06-15
Abstract: PURPOSE:To suppress the corrosion by an electrolytic effect and to improve a recording sensitivity by forming the recording medium of two layers; a magneto-optical recording layer and a reflecting layer and constituting the reflecting layer of >=2 kinds of dielectric layers. CONSTITUTION:This recording medium has the two layers; the magneto-optical recording layer 3 and the reflecting layer 4. The reflecting layer 4 is constituted of >=2 kinds of the dielectric layers. Namely, >=2 layers of the dielectrics having a large difference in refractive index are laminated at adequate film thicknesses, by which the reflectivity and absorptivity are made into prescribed values and such layers are usable as the reflecting layer 4. Since such reflecting layer 4 does not contain metallic films, the electrical conductivity is extremely low and since corrosion current does not flow, the electrolytic corrosion effect is not generated. The heat conductivity is lower than the heat conductivity of the reflecting layer contg. the metallic films and, therefore, the recording sensitivity is improved. The reliability and recording sensitivity are improved in this way.

Title: Treating method for exhaust gas containing nitrogen oxides
Inventor: KATOU AKIRA
IPC: B01J23/14
Filed: 1977-12-23
Abstract: PURPOSE: To efficiently treat exhaust gas by taking out catalyst the activity of which has been lowered owing to salt deposition; regenerating the catalyst with heating; and selectively absorbing SOx in gas scattered from the catalyst surface to recycle NH 3 .  
     CONSTITUTION: After adding a predetermined amt. of ammonia 2, exhaust gas 1 contacts with denitration catalyst 4 based on TiO 2  and/or SnO 2  at 150W330°C in denitration tower 3 to reduce NOx to N 2  and H 2 O. At this time, SO 3  out of SOx contained in gas 1 reacts with NH 3  to form (NH 4 ) 2 SO 4 , which is deposited on catalyst 4, lowering the catalytic activity. So, part of catalyst 4 is taken out and fed to regeneration tower 5, where hot gas 6 of 350W600°C is passed to evaporate the (NH 4 ) 2 SO 4 , thus regenerating the catalyst. The hot gas contg. NH 3  and SOx is fed to SOx removal tower 7, where the SO 3  alone is absorbed with SO 3  absorbent 8, and the NH 3 -contg. gas is added to untreated exhaust gas 1 and reused.

Title: Generating device for tracking error signal
Inventor: YOSHIO JUNICHI
IPC: G11B7/09
Filed: 1984-07-24
Abstract: PURPOSE:To generate an invariably tracking error signal by using a stable three-beam system normally and switching the system to a one-beam system when a flaw of a recording medium is detected. CONSTITUTION:When the disk has no flaw, a signal switch 22 selects the subtraction signal (three-beam system) of a subtracter 5 for outputs of a couple of detectors 9 and 10 and outputs it as a tracking error. When the part where there is a flaw approaches, a precedent photodetector 9 decreases in detection signal level owing to a flaw and the output of a comparator 18 is inverted; and a controller 24 outputs selectively a tracking error signal (one-beam system) as the subtraction output of a subtracter 6 through the switch 22 for a specific time in response to the inversion. Consequently, the tracking error signal tolerant to the flaw is generated.

Filed: 1981-09-30
Abstract: PURPOSE:To obtain a print output with high print quality, by adding a circuit compensating a specific pattern effect to a laser automatic output control circuit at each scanning, in a print output device taking laser as a light source. CONSTITUTION:In a laser output automatic control circuit, a circuit connecting a laser 1 and resistors in serise, is added with a compensation circuit 8 in parallel, in series connection of a resistor R and a capacitor C of a suitable constant.  Thus, at the initial state of laser driving, an impedance of an RC series circuit is decreased and a current flowing to the ciucuit 8 is increased, and the impedance of the circuit 8 is gradually increased, the current flowing to the laser 1 is  increased, allowing to compensate the temperature characteristics of the laser 1.  Thus, the laser output fluctuation to a photo sensing element medium is almost  less and uniform output can be obtained, allowing to obtain the print output with high print quality without uneven print.

Title: Fabrication of semiconductor device
Inventor: HARADA TAKASHI
IPC: H01L21/306
Filed: 1993-06-25
Abstract: PURPOSE:To allow anisotropic etching by varying the impurity concentration in a thin film stepwise through the use of proportional relationship between the impurity concentration of the thin film and the etching rate of wet etching thereby differentiating the etching rate and varying the etching profile. CONSTITUTION:At first, films 2 having different impurity concentration are formed stepwise. A photoresist pattern 1 is then formed by photolithography. When wet etching is conducted, an anisotropic etching profile is obtained due to the difference of etching rate caused by the variation of impurity concentration. Consequently, coverage of film is improved in the following metallization step, breakage at the level difference is eliminated, and contact with neighboring circuit due to overetching is also eliminated resulting in the increase of fabrication yield.

Title: X-ray sensitive receptor
Inventor: TEJIMA AKITOMO
IPC: G03G5/14
Filed: 1981-09-30
Abstract: PURPOSE:To greatly enhance sensitivity to X-ray exposure, by converting X- rays into visible light high in sensitivity of a photoconductor using a fluorescent substance. CONSTITUTION:An X-ray fluorescent substance layer 2 is formed on a substrate 1, on this layer a transparent conductive layer 3 is provided, and a photoconductor layer 4 is formed as the uppermost layer. This photoreceptor does not absorb X-rays appreciably upon exposure to them, but the layer 2 absorbs most of the rays, emitting visible light high in sensitivity of the photoconductor. Upon absorbing the visible light, the layer 4 generates electrons and holes, each moving in the direction opposite to each other by action of an electric field due to the surface charge of the layer 4. The carriers that have reached the surface of the layer 4 neutralize the initial charge to form an electrostatic latent image, thus permitting X-ray sensitivity to be raised by 20-100 times by use of the fluorescent substance layer 4.
