Title: Cross polarized wave receiver
Inventor: OTSUKA HIROYUKI
IPC: H04J11/00
Filed: 1987-12-28
Abstract: PURPOSE:To eliminate cross polarized wave interference in an excellent way by compensating the timing phase fluctuation of a different polarized wave signal and the interference component of a main polarized wave signal in a propagation line by means of a variable delay circuit. CONSTITUTION:A delay setting circuit 10 detects an interference component leaked from a different polarization wave into a main polarized wave and respective propagation state of the different polarized wave signal from the tap coefficient of a transversal waveform equalizer 7 and a transversal filter 12 and sets the delay of a variable delay circuit 11 to approach the timing phase deviation to the initial setting state. The transversal filter 12 adjusts the amplitude and phase of the output of the variable delay circuit 11, outputs a compensation signal being in-phase and equal amplitude to the interference signal included in the output of the transversal waveform equalizer 7 and subtracts it from the output of the transversal waveform equalizer 7 by a subtractor 13.

Title: Separate type connector
Inventor: FUKAMACHI MAKOTO
IPC: H01R13/629
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To lower the fitting force while saving the space by making respective cam parts have different cam curve lines as to make fitting timing of respective separate housings different. SOLUTION: Two separate housings 1A, 1B are so installed in the inside of a hood part 6 of a male housing 1 as to be fitted in parallel. A slider 3 which can be pushed in from a side is installed in the male housing 2. Separated cam grooves 25A, 25B with which follower pins 10 uprightly installed in respective separate housings 1A, 1B are fitted are grooved in the slider 3. When the slider 3 is pushed in, the separate housings 1A, 1B are successively fitted. Since the peaks of the fitting forces are made shifted, the force necessary for fitting is further lowered as compared with the force for fitting together. Since it is sufficient to linearly push the slide 3 from a side of the male housing 2, a narrow space is sufficient for operation.

Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a method of operating and controlling a shot cleaning device for disseminating a suitable amount of steel balls according to the mass flow of dust passing in a front flow of a heat exchanger. SOLUTION: In order to calculate and estimate a mass flow of dust flowing in an exhaust gas passage on the front flow side of a heat exchanger 5, based, for instance, on an estimated dust amount for every type of coal to be burned in a boiler and a load of the boiler, and to regulate the amount of steel balls per unit area to be disseminated in a heat exchanger to an optimal value, according to the estimated value, the circulation rate of steel balls is increased or decreased by a steel ball transport machine 9 and a steel ball distribution machine 2. By carrying out the above control method, the steel ball amount per unit area passing in the heat exchanger 5 can be instantaneously controlled to an amount suitable for the mass flow of dust, in response to the increase or decrease of the dust mass flow, according to change in the boiler load and the coal type. Therefore, increase in pressure loss due to lack of steel ball dissemination, and abnormal abrasion of a heat exchanger tube of the heat exchanger 5 due to excessive dissemination of the steel balls can be reduced, to thereby enable stable operating of the heat exchanger 5.

Filed: 1989-12-22
Abstract: PURPOSE:To prevent a thin film which is formed fro generating pinholes or becoming irregular in structure by prescribing the height of a projection part on the surface of a substrate and the radius of curvature of the tip respectively. CONSTITUTION:A 'Pyrex(R)' plate with surface roughness Rmax 0.5 mum (R is equivalent to 0.5d) is used as a substrate 1 and the surface is etched lightly to form the projection part with an about 250Angstrom (equivalent to 0.042d) radius of curvature. Then a metallic electrode 12 made of Cr, an a-Si film 13, and an ITO film 14 are laminated in order on the substrate 1 to manufacture an optical sensor 15. Thus, the frequency of the generation of defective bits becomes minimum when the projection part on the substrate surface where the thin film element is formed satisfies conditions R<4d and r>0.04d (where R is the height of the projection part based upon the mean value of the surface roughness, (r) is the radius of curvature of the projection part tip, and (d) is the film thickness of a thin film element activation part).
