Patent JP-H05335846-A (JP)
Title: Amplifier circuit
Inventor: FUJII TAKASHI
IPC: H03F3/30
Filed: 1992-06-03
Abstract: PURPOSE:To prevent disturbance in an output waveform by detecting a current difference between drain currents flowing to a Pch and Nch TRs to apply an input offset voltage to a 1st or 2nd operational amplifier circuit to block cut-off of an output stage transistor (TR). CONSTITUTION:Since TRs 1-6, 1-7, 2-6, 2-7 are connected in parallel with TRs 1-3, 1-4, 2-3, 2-4, a current flowing to the TRs 1-6, 2-7 is increased. Furthermore, a current flowing to the TRs 1-7, 2-6 is decreased. Thus, the potential at a node 1-A increases and a potential at a node 2-A decreases. With switches 1-9, 2-9 closed, the TR 1-8 is turned on and the potential at the node 1-B rises. On the other hand, the TR 2-8 is turned off and no effect is given on the potential at a node 2-B. As a result, a current flows to an output stage of an operational amplifier circuit 1-2, an input offset voltage is added and the circuit acts like eliminating a specific input offset voltage of the circuit 1. Thus, the cut-off of the TRs 1-4, 2-3 is prevented.

Abstract: PURPOSE:To form a highly reliable high-density semiconductor device by forming a tungsten structure therein. CONSTITUTION:A thin chromium layer 14 is deposited onto a preselected surface 12 of a semiconductor layer 10 by means of low-pressure chemical vapor growth. A tungsten layer 16 is formed uniformly over thus deposited chromium layer 14. A second thin chromium layer 18 is deposited on the tungsten layer 16. Then, a photoresist layer 20 deposited over a chromium layer 18 is etched by exposing light with a predetermined light pattern to form a photoresist mask 22. The second chromium layer 18 is etched using oxygen/chlorine plasma to form a chromium mask 24. The tungsten layer 16 is etched by using carbon tetrafluoride/chlorine plasma to form a tungsten structure 26. Any part in the chromium mask and the first chromium layer which is exposed by the tungsten etching process is eliminated through the use of an etching plasma consisting of an oxygen ion and a chlorine ion.

Title: Range finder
Inventor: SAITO TATSUO
IPC: G02B7/32
Filed: 1995-06-09
Abstract: PURPOSE: To obtain highly reliable measured range results by providing two kinds of range-finding means, i.e., an active measuring means and a passive measuring means, and selecting measured results by either means. CONSTITUTION: An exterior luminance is detected by a luminance detection part L and, a range is measured by an active measurement part A and a passive measurement part P. The measured results are sent to a measured value selection circuit 40 via corresponding range-finding operation circuits 13 and 23. When the exterior luminance obtained by the detection part L is high and not smaller than a predetermined value, the selection circuit 40 selects and outputs the measured value by the measurement part P. If the exterior luminance is low and not higher than another predetermined value, the circuit 40 selects the measured value by the measurement part A. Moreover, when the exterior luminance is middle between the two predetermined values, and if the measured values are greatly different, the circuit 40 judges that the measured value by the measurement part A is incorrect and selects the measured value by the measurement part P. On the other hand, if the difference of measured values is small, the circuit 40 judges that both measurement parts are normal and selects the measured value of the more accurate measurement part A.

Title: Abnormal-sound detecting apparatus
Inventor: YAMADA IZUMI
IPC: G21C17/00
Filed: 1993-06-15
Abstract: PURPOSE:To prevent the removal of an abnormal-sound component as much as possible when normal sound is removed by extracting only the component, which is synchronized with the rotation of a pump from the detected sound, and judging the presence or absence of the abnormality based on the magnitude of the synchronized component. CONSTITUTION:The number of rotation of a pump 22 is detected with a rotation sensor 31. The sound wave, which is propagating in the casing, is detected with a sound sensor 32. The detected number-of-rotation signal and sound signal undergo wave shaping and amplification with a tachometer 33 and a charge amplifier 34. The signals become the outputs corresponding to the respective central frequencies through a bank filter 41 comprising many BPFs. In a synchronized-component extracting and processing part 42, the detected signals of the sound waves are accumulated in response to the reference timing of the rotation, and only the rotary synchronized component is extracted. In a single-component abnormality detecting part 43, the presence or absence of the abnormality is discriminated for every central frequency of the BPF. In a total-component-abnormality detecting part 44, the presence or absence of the abnormality is discriminated based on the extracted data of the synchronized component from the observed entire frequency band.

Title: Wind mill of wind force generator, etc.
Inventor: YAMAMURA HISASHI
IPC: F03D7/04
Filed: 1977-11-30
Abstract: PURPOSE: To effectively start wind mills at low wind velocity, and to efficiently turn them at high wind velocity, by shaping an angle of mounting a wing to a rotary plane of the wing in a variable form.  
     CONSTITUTION: A hub 3 is mounted to a power shaft 1 connected to a wind mill generaor 2 in a revolution-free shape. A projection 4 is installed to an inner portion of one flank of the hub 3. Since a wind mill does not generate rotary torque when there is no wind, the hub 3 is adjusted to ensure that a wing 8 is located at an angle of mounting the wing to a rotary plane by the action of a spring 5. When wind velocity is formed, the wind mill starts its revolution while the power shaft 1 is subject to rest force of preventing the revolution of the wind mill by the braking force of the generator 2, thus resulting in the starting of the relative revolution of the power shaft 1 and the hub 3 against the action force of the spring 5, then turning a wing shaft 9 until a pin 6 and the projection 4 contact. Thus, the wing 8 is automatically adjusted at asmall angle of mounting the wing to the rotary plane.

IPC: G08B13/12
Filed: 1990-06-01
Abstract: PURPOSE: To form integrally with a structure and detect a position of a damage quickly by arranging a bundle of optical fibers with many bend patterns on a building or inside the building. CONSTITUTION: The apparatus is constituted of a plurality of optical fibers 2 arranged in a composite material matrix or buried in the matrix. The fibers 2 are arranged in a pattern so as to cover and monitor a sufficient area better than when arranged in a slim band. In the pattern, the fibers 2 are bent with a small radius and one fiber 2 is allocated to a specific area 3. Since the fibers 2 are arranged to be adjacent to each other, a damage having a diameter of a distance of fibers 2 can be detected via a photodiode from a decrease of a transmittance of light from a light source at an area of the damaged fiber 2. Moreover, the area is covered with a minimum count of fibers 2 and the breakage of fibers 2 occurred by bending is prevented by enlarging the radius of curvature.
