Title: Method of manufacturing brush for polishing curved section
Inventor: HATSUTORI KOUJI
IPC: B24D13/10
Filed: 1983-08-30
Abstract: PURPOSE:To simply form a brush for polishing a curved section, which has a long life with less nonuniform or partial abrasion, by securing channel-like brushes to the surface of a curved flange formed from a steel plate by press- forming. CONSTITUTION:A flange 2 is formed such that a rectangular steel plate 1 is curved widthwise by press-forming, and bolt holes are formed at the four corners of the plate 1. A channel-like brush 5 is formed such that steel wires 4 are inserted into a channel 3 which is then fastened by press, and are cut into a predetermined trim length. Then, the channel brushes 5 in five rows are wedled and secured to the concave surface side 21 of the curved flange 2. The curved polishing brush 6 thus formed is secured, with the concave side thereof being directed inward, to a rotary body circularly rotating, by means of bolts so that a steel round bar W rectilinearly travelling in the longitudinal direction thereof is polished. As a result, the round rod may be polished uniformly at a high speed, and as well the brush will not be unevenly worn.

Abstract: PURPOSE:To simply detect a failure of a power transmission system by generating the output of a measuring timing with zerocross signal for detecting the zero time points of the instantaneous values of respective transmitting current and receiving current, at a power transmitting station and a power receiving station, and by measuring the transmitting and receiving current at the time points to compare them with each other. CONSTITUTION:A power transmitting station 10 and a power receiving station 20 are connected to each other with a transmission line 5. From the output of the generator 11 of the power transmitting station 10, a first zerocross is detected 12, and a first timing pulse is generated 14, and by a first measuring circuit 16, the instantaneous value of transmitting current is found. The found instantaneous value is transmitted 19 to a comparator 30 via a first signal- transmitting circuit 18. In the quite same manner as at the power receiving station 20 also, from receiving current, a second zerocross is detected 22, and a second timing pulse is generated 24, and by a second measuring circuit 26, the instantaneous value of the receiving current is found. The found instantaneous value is transmitted 29 to the computor 30 via a second signal-transmitting circuit 28. By the comparator 30, the output 19 and the output 29 are compared with each other, and if there is an abnormal state, alarm is given. As a result, by a simple circuit for requiring no main and subordinate relationship, a failure in a system is detected.

Title: Flame spraying method
Inventor: TAKEUCHI JUN
IPC: C23C4/12
Filed: 1988-06-29
Abstract: PURPOSE:To reduce residual stresses in a coated layer and a base material and to prevent the deformation of theses coated layer and base material by determining respective residual stresses of the coated layer and the base material from respective characteristics of the base material and the flame spraying material, the service temp. of the coating, etc., and then determining flame spraying temp. based on the obtained residual stresses. CONSTITUTION:Stresses generated at the time when flame spraying grains are allowed to collide against a base material and cooled are determined from the relationships among the respective values of physical properties of the base material and a flame spraying material, respective thicknesses of the base material and the flame spraying material, service temp. at the time of coating by flame spraying, and flame spraying temp. Further, the deformation and also the stresses of the base material and the film generated in the course of flame spraying are determined. Moreover, the deformation and stresses of the base material and the film in the course from the conclusion of flame spraying to the attainment of cooling down to the prescribed temp. are determined. Based on the above, the flame spraying temp. at which prescribed stresses can be generated is determined, and then, the temp. of the base material is set at the flame spraying temp. to undergo flame spraying. By this method, a film free from cracks can be obtained, and the characteristics of the film, such as corrosion resistance, high-temp. corrosion resistance, acid resistance, electric or thermal conductivity, and insulating property, can be improved.

Title: Method of deasphalting and demetallization of crude oil
Inventor: CHIEZAARU SABASUTAANO
IPC: C10G21/16
Filed: 1991-06-04
Abstract: A process is described for deasphalting and demetallizing crude petroleum or a fraction thereof containing asphaltenes and metals, in which:   said crude or its fraction is brought into contact with an organic carbonate, the operation being conducted in the homogeneous liquid phase, until a solid residue rich in asphaltenes and asphaltenic metals precipitates; and   said solid residue is separated from the homogeneous liquid phase.   After separating the solid the homogeneous liquid phase can be cooled to separate an oil-rich refined liquid phase from an extracted liquid phase rich in organic carbonate. The separation of the extracted and refined liquid phases can also be achieved by adding a liquid solvent more polar than the carbonate, with or without cooling.

Title: Humidity sensor
Inventor: MASUO TASUKU
IPC: G01N5/02
Filed: 1982-09-13
Abstract: PURPOSE:To enable accurate detection of relative humidity by reading changes in the oscillation frequency depending on a drop or a stop of the oscillation due to a dielectric relaxation based on the decrease in the resistance value due to humidity absorption of a piezo-electric body. CONSTITUTION:A piezo-electric body 2 is formed on the side of a tuning fork type vibrator body 1 and an electrode 3 thereon 2. The electrode 3' is preferably an island or net in the shape considering hygroscopicity and connected to a widely accepted oscillation circuit as surrounded by the broken line 4. As illustrated, the oscillation frequency decreases down to 65% in the relative humidity and the oscillation stops at this relative humidity of 65%. The percentage of the relative humidity can be confirmed by reading the oscillation frequency. The oscillation stops at the relative humidity of 65%, when the resistance value is close to 10<6>OMEGA. No piezo-electric property is indicated below this resistance value. Thus, the relative humidity can be detected exactly by reading changes in the oscillation frequency of the vibrator.

Title: Pilot signal detector circuit
Inventor: MIYAMOTO BUNICHI
IPC: H04L27/00
Filed: 1977-12-28
Abstract: PURPOSE:To prevent an image frequency from being generated by using LPF. CONSTITUTION:Receiving wave fR including pilot signal fP is applied to mixer 1 together with a local oscillated signal of frequency fL. The local oscillated signal is obtained from local oscillator 5 which is frequency-swept by triangular wave oscillator 4. The center frequency for sweep is made equal to the frequency of pilot signal fPZ, and the sweep width is made wider than the frequency fluctuation width  of pilot signal fP. When pass bands of LPF 6 are denoted as 0 to f1, the output of  LPF 6 can be obtained only when the frequency of output (fP to fL) of mixer 1 has  a value between 0 and f1. By conditions of LPF 6, the beat frequency between  signals other than fP and fL are all higher than f1, so that this frequency cannot pass through LPF 6.

Title: Network control method for electric power
Inventor: SUDA HIROHARU
IPC: H02J3/14
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To easily and surely control electric power without requiring a control board by leveling a power source load by diffusing phases giving a peculiar control phase by inverting bits. SOLUTION: In a network control method for electric power, each network has a peculiar number. To a network which can install 256 sets maximum, for example, numbers from 0 to 255 are given. Here, the numbers are bit- inverted. Then electric power is distributed by using the phase as the initial value. A power command from the outside is given to the network regarding 100% as 256 (Full). The command is given to the phase at every break of the power source frequency and, only when the command reaches 'Full', a power is bed. When the power is bed, 'FULL' is subtracted from the phase. When this method is made, the phase is maintained, because the sum of the values added when the power feed is repeated by 'Full' times becomes a command *Full and the sum of the remainders also becomes a command Full*. Namely, this method utilizes the so called principle of DDA.
