Filed: 1991-06-27
Abstract: PURPOSE:To eliminate a foreign matter and to stabilize a length of a bird beak by forming an SiC layer when carbon is selectively implanted to form a selective oxide film, thereby selectively forming the oxide film. CONSTITUTION:A pad oxide film 2 is formed on a semiconductor substrate 1, a selectively oxidizing resist film 4 is so formed thereon as to allow a part formed with a LOCOS oxide film to remain, and carbon 8 is implanted. The carbon 8 is so implanted in a part in which the film 2 is exposed on the surface as to reach not only in the film 2 but also the substrate 1 of its lower layer. Then, the film 4 is peeled, and a LOCOS oxide film 5 is formed. In this case, since it is heated to about 9O0 deg.C, the silicon is reacted with the carbon to form SiC in the film 2 thereby to prevent oxidation, and the film 5 is formed only on the part covered with the film 4. Thus, a length 7 of a bird beak is stabilized.

Title: Malfunction detector for motor
Inventor: TAKANO TOSHIO
IPC: H02P7/06
Filed: 1989-06-21
Abstract: PURPOSE:To immediately safely solve if a malfunction occurs in the rotation of a motor by opening switch means interposed in series with a motor winding when the motor does not normally rotated within predetermined time if the winding is connected to a motor drive power source according to a drive command of the motor. CONSTITUTION:When a motor 10 is not rotated within predetermined time, a rotation sensor 12 does not output a pulse signal. Accordingly, a DC voltage of a constant-voltage circuit 2b remains applied across a capacitor 9b of a voltage generator 9. A voltage is not generated between two output terminals of a rectifier 9c, and the voltage of a capacitor 3a is gradually lowered due to discharge. Accordingly, the amplitude of an oscillation output of a self-excited oscillator 4a is lowered. If the amplitude becomes less than a reference value of a level detector 4b, a voltage is not supplied to a relay coil 4f, the coil is not excited, and a motor winding 10a is disconnected from a power source 8.

IPC: H04W92/10
Filed: 1994-07-08
Abstract: PURPOSE:To synchronize the phases of transmitted signals transmitted from respective radio base stations without using any reference signal from another device by generating a radio frame reference signal based on phase difference between a reference signal for radio frame synchronization and a detected synchronizing signal. CONSTITUTION:At the radio base station, in order to decide the transmission reference timing of the present station, first of all, antennas 15 and 16 are respectively connected to receivers 12 and 13 and radio signals transmitted from the peripheral radio base stations to a mobile station are received at starting time to turn on the power source of the present station and to start it. Those received signals are outputted from the receivers to a synchronizing signal detecting means 18. Then, the synchronizing signal detecting means 18 detects the synchronizing signal out of these received signals and outputs a phase correcting signal to a phase correcting means 17. As a result, the phase correcting means 17 generates the transmission reference timing of the present radio base station (present station) based on a reference clock signal received from a cable line 19 and the phase correcting signal from the synchronizing signal detecting means 18 and supplies it to a transmitter 11.

Filed: 1990-06-15
Abstract: PURPOSE:To realize a woody sound by providing plural spaces inside in the thickness direction of the lid and increasing the timbre relative material property value E/G of the lid. CONSTITUTION:The lid 1 is formed by connecting plural straight grained timber veneers 2, 2..., a long dowel is fitted at right angles to the grain direction M, and lid rods 10 are fitted to the veneers while intersecting orthogonally with the grain direction. Grooves 5, 5... formed in the veneers 2, 2... in the grain direction M are widest at the center part of the lid 1 and become narrower toward the end parts. The grooves formed in both the joined surfaces of the joined parts of the veneers 2 and 2 are matched with each other to form a hollow part. The strength of the part of the groove to shearing deformation is decreased and the characteristic value of the whole lid 1 corresponding to a coefficient G of lateral elasticity becomes small. Consequently, the timbre relative material property value (E/G) is increased and the warm woody sound is realized.

Filed: 1980-11-10
Abstract: PURPOSE:To simplify the circuit constitution, by eliminating a relay by switching plural amplifiers with use of a change of level of the switch control signal. CONSTITUTION:Amplifiers 22A and 22B amplify plural input signals individually. A switching circuit 24 switches selectively each amplifier according to the level of the switch control signal.

For instance, the amplifier 22A is switched to the amplifier 22B to ensure the working for either one of these amplifiers. Thus the reproduced output of a magnetic head 36B is amplified by the amplifier 22B and furthermore by middle-stage amplifiers 26 and 28 to be supplied to a tone control circuit 62 via a terminal 44.

Abstract: PURPOSE:To surely discriminate a preceding vehicle existing on the traveling rails of a vehicle by providing a transmitting means, a direction/distance measuring means, a distance correcting means, etc. CONSTITUTION:A pulse modulator 71 outputs a pulse modulating signal successively to laser diodes 55, 57, 59 to control the driving of these diodes and outputs a light radiating signal to an arithmetic circuit 77 synchronously with the output of the pulse modulating signal. An amplifier 73 amplifies a detecting signal obtained by photoelectrically converting the light detected by a photodetecting element 67, and simultaneously comparator 75 extracts a signal exceeding a set level out of the detecting signal as the reflected signal of a laser beam radiated from an optical output part 43 by a reflecting body and outputs the extracted signal to the circuit 77. The circuit 77 calculates the existing direction of the reflecting body and the distance from the reflecting body on the basis of the input time difference between the light radiating signal and its reflected signal. The calculation of the distance is executed by using the input time difference. The direction is decided from the light radiating signal.

Abstract: PURPOSE:To easily control channels by performing switching only under the wavelength conversion control of a wavelength converting circuit by using (mXn) kinds of wavelengths by an optical channel which has multiplicity (n) and inputs light signals from (m) time-division multiplex highways. CONSTITUTION:When time-division multiplex highway optical signals (aa1)-(aa3) having wavelength lambda0 are inputted from input terminals AA1-AA3, wavelength converting circuits AB1-AB3 convert the highway light signals to wavelength lambdaij for each time slot, obtaining ab1-ab3. Then, they are coupled by an optical coupler A to obtain a wavelength multiplexed highway signal ac, which is branched by an optical branching device AD quantitatively equally to four outgoing lines. Optical delay circuits AE1-AE4 obtain an out-of-phase signal containing information on an input highway. Then, the optical branching filters AF1-AF4 send outputs to three outgoing lines corresponding to the respective output highways. The optical couplers AG1-AG3 couples output signals of the optical branching filters in three groups. Those are converted to wavelength lambda0 by wavelength converting circuits AH1-AH3 and outputted.
