Title: Diagnosing device for majority deciding circuit
Inventor: ARITA SETSUO
IPC: H03K19/23
Filed: 1987-09-30
Abstract: PURPOSE:To evaluate the soundness of the majority deciding circuit by applying a test signal of an opening/closing circuit which constitute the majority deciding circuit and detecting a current for every element constituting OR. CONSTITUTION:Signal processors 1 and 2 input and process signals outputted by redundant sensors A1-N1 and A2-N2 and output trip signals when the signals exceed a prescribed value. The trip signals of the processors 1 and 2 are supplied as signals (a) and (b) to opening/closing means 12 and 13 which constitute the majority deciding circuit through changeover switches 3 and 4. A test signal is supplied to the contact of one of the switches 3 and 4 from the diagnosing device 11 and the signals (a) and (b) are switched to the test signal with switching commands 7 and 8. Then the outputs of current detecting means 14 and 15 in response to the test signal are inputted as signals 9 and 10 to the circuit 11 to diagnose its abnormality. Consequently, a fault of each opening/closing means is decided to evaluate the soundness of the majority deciding circuit.

Abstract: PURPOSE:To prevent oxygen to be diffused rapidly so as to inhibit the formation of birds's beaks and to realize higher integration, by covering the end faces of a nitride film covering an active region and the etched end faces of a semiconductor substrate with a polycrystalline silicon film before field oxidization. CONSTITUTION:The main surface of a P type silicon substrate 10 is lightly heat oxidized to form an SiO2 film 11 over the whole surface and an Si3N4 12 is further deposited over there. After a photoresist film 13 is formed, pattern exposure, development and so on are carried out to leave the photoresist only on the active region 14, while not only the nitride film 12 and the oxide film 11 but also some thickness of the silicon substrate 10 are etched away. Subsequently, a polycrystalline silicon 15 is deposited on the whole surface, and RIE is carried out so that the polysilicon 15 is left only on the side faces of the part constituting an active region. The substrate in this state is heat oxidized to form a field oxide film 16 only on the region isolating the elements without penetrating into the active region. Thus, formation of bird's beaks can be prevented.

Abstract: PURPOSE:To send a syndrome to a terminal station without increasing redundancy by providing an error pulse generating circuit generating an error pulse able to be corrected in an output of an error correction coding circuit when a code error is detected by an error correction decoding circuit. CONSTITUTION:A redundant bit is added to a transmission signal at the sender side to apply error correction to an information signal.

Abstract: PROBLEM TO BE SOLVED: To oxidize NO to NO2 and to adsorb and remove NO2 by using an NOx adsorbent contg. nickel oxide and copper oxide as essential components. SOLUTION: This NOx adsorbent contains nickel oxide and copper oxide as essential components. The oxides may exist as a mixture but it is preferable that the oxide be mixed as uniformly as possible by adding a precipitant to salts as precursors of nickel oxide and copper oxide and carrying out coprecipitation.

The nickel oxide and copper oxide content (Cu/Ni+Cu on weight basis) is 1-50%, preferably 3-10%. In the case of <=1% Cu content, the efficiency of addition is low. In the case of >=50% Cu content, the basic characteristics of nickel oxide are deteriorated.

IPC: G03G15/22
Filed: 1986-10-15
Abstract: PURPOSE:To prevent sticking of a toner image to a heating roller by attracting the toner image transferred on a film by the electrostatic attraction force of the electric charge of the reverse polarity on the rear surface of the film. CONSTITUTION:The film F on which the toner image is transferred is applied with the electric charge of the same polarity as the polarity of the toner image T transferred atop the film by a 1st corona discharger 4. On the other hand, the charge of the polarity reverse from the polarity of said charge is induced on the front layer of the film F and the toner image on the film receiving the charge of a strong negative polarity is attracted by the electrostatic attraction force in the direction of the rear surface of the film. Namely, the toner image is attracted to the front surface of the film and is prevented from sticking to an upper roller 2 even during the heating and pressurizing under rotation for the purpose of being transferred and fixed by the upper and lower rollers 2, 3.

Title: Identifying device for minute part element
Inventor: KUWABARA MASASHI
IPC: G01N23/227
Filed: 1994-10-12
Abstract: PURPOSE: To prevent a device from broken and malfunctioning by allowing adjustment of angle of incident X-ray on the bottom face of a sample for reduced X-ray passing through from the bottom face into a probe and noise. CONSTITUTION: X-ray is, by adjusting angle with a sample holding base 7 provided with positioning mechanism, made incident on the bottom face of a sample 6 from an X-ray source 1 at the total reflection angle. So that, X-ray does not transmit through a scanning type tunnelling microscope(STM) probe 2 driven by a piezoelectric element 3. In case of non-total reflection angle, the X-ray transmitting through the sample 6 strikes the probe 2, so that, electrons of the prove 2 is excited, and which causes noise. Further, in a photoelectron signal amplifier 5 amplifying signal from the probe 2, malfunction and breakdown are occurred in a circuit when the X-ray strikes. And further, high energy of the X-ray eliminates a polarization of the element 3, so that, the element 3 is broken. To avoid these, the X-ray is made incident from the bottom face of the sample at the total reflection angle.

Title: Vibration-proof camera
Inventor: WASHISU KOICHI
IPC: G03B7/16
Filed: 1992-08-24
Abstract: PURPOSE:To prevent the influence of vignetting from carelessly being made large by providing an aperture control means which controls the aperture of the vibration-proof camera according to the relation between information on the photographic state of the camera and the operation state of a vibration- proofing device. CONSTITUTION:Aperture information from an aperture information output means 12 is inputted to a display means 13 and a limiting means 11. This aperture information is a larger and larger output as the aperture is smaller and smaller and the limit level of a limiting means 11 varies according to the output. Then, the limiting means 11 has a function which cuts a large-amplitude part, shown by 14b, of the hand shake output 14a of a vibration detecting means 14 during operation, and the extent of cutting is larger and larger as the aperture is smaller and smaller. A driving means 15 faithfully drives a correction optical means by using the signal of the handshake output 14b after the large amplitude is cut as a command signal. The correction optical means is therefore not driven with the large amplitude and the influence of vignetting is made small.
