Title: Swirl preventive shape of suction waterway
Inventor: ENOMOTO TAKASHI
IPC: F04D29/54
Filed: 1994-09-27
Abstract: PURPOSE: To increase critical flow velocity by forming the outside of a bending part of a suction waterway so as to smoothly contact from inside with an extension line having a throat diameter in an almost perpendicularly curving suction waterway. CONSTITUTION: A downstream part 5 of a curved part 4 of a suction waterway 3 is formed so as to smoothly contact from inside with a straight line. A inside part 6 of the curved part 4 is also smoothly connected to a throat part 2 so as to correspond to an outside part 5. Therefore, since the downstream part 5 of the curved part 4 smoothly contacts from inside with the throat part 2, a flow S becomes a largely and smoothly curved flow S1 in the curved part 4, and flows in the throat part 2. Therefore, a swirl by a reversal flow as usual is not generated. As a result, critical velocity of flow speed Vs can be increased to about three times of usual critical velocity.

Abstract: PURPOSE:To enough suppress ajumping-in noise from respective noise sources and to improve the S/N of a reproducing video signal by providing a means to prevent the picture quality degradation of a reproducing image with a video signal to be selectively outputted. CONSTITUTION:On a magnetic tape 1 of a camera-integrated video tape recorder, a synthesizing signal from a video camera or a TV receiver is recorded and the recorded synthesizing signal is reproduced. An LPF4 and an LPF5 are provided to be used at an SP mode time and an LP mode time to this device and the passing band ot the LPF5 is made narrower than the passing band of the LPF4. Then, the unnecessary component of a high area in the LP mode is limited. Since the passing band of the LPF4 is wide, the influence of the jumping-in noise to a reproducing signal in the SP mode is reduced and the degradation of the frequency characteristic of the reproducing signal is decreased. By a switch 6 controlled by the control of a mode switching control circuit 20, the respective modes are selected and inputted to reproducing FM equalizing circuits 7 and 8 and the output is processed by succeeding respective circuits.

SOLUTION: A pair of detecting coils 12, 13 are formed symmetrically through a hole 11 in the same size by a conductive pattern on an insulating board 10. Further, the back parts 15a, 16a of cores 15, 16 fixed to a rotary shaft 14 are so simultaneously wound with exciting coils 17 together with the shaft 14 in a surrounding manner, and magnetic fluxes are applied to the coils 12, 13 via arms 16b, 16c. Accordingly, the arms 16b, 16c move as the shaft 14 is rotated, and output voltages corresponding to the crossing area with the fluxes are respectively generated at the coils 12, 13. Since the voltages generated at the coils 12, 13 are so connected as to be added to each other, the voltage of twice as large as the voltages generated at the coils 12, 13 is obtained as a whole.

Title: Atm switching system
Inventor: EZAKI HIROSHI
IPC: H04L47/20
Filed: 1990-08-31
Abstract: PURPOSE:To prevent the algorithm of control from becoming complicated by executing the request of rejection rate and the report of a traffic characteristic related to a rejection impermissible cell group among the cell groups belonging to a virtual channel to a network, and making the network secure the rejection rate at the time of the request of setting the virtual channel. CONSTITUTION:At the time of the request of setting the virtual channel, the propriety or the impropriety of the setting of the requested virtual channel is decided so that a terminal side executes the request of the rejection rate related to the rejection impermissible cell (CPL=0) to the network and the network secures the rejection rate only in respect of the rejection impermissible cell. Accordingly, in respect of a rejection permissible cell (CLP=1), both the report of the traffic characteristic and the request of the rejection rate from the terminal are not executed, and the network too does not secure the rejection rate. Then, in the network, preferential control is executed to the rejection impermissible cell, and in addition, the cell group quantity in the course of communication of the rejection impermissible cells is supervised for every virtual channel. Thus, the quality of the rejection impermissible cell can be surely secure.

CONSTITUTION:A primary molded tubular body (a) is set in a recessed part 14 at the center of a lower mold 13. A movable mold 15 at both, right and left sides of the lower mold, 13 is driven by a hydraulic cylinder, so that the tip part, 16 of the movable mold 15 is brought close to and away from the tubular body (a) at the inner side of the tubular body (a). The tip part 16 is tapered, and two kinds of slide cores 17, 18 are alternately provided in the peripheral surface of the end part 16 to slide in frictional contact with the tapered end part. The slide cores 17, 18 are contracted and expanded by the movement, of the movable mold 15. When the movable mold is inserted, the distance of the slide cores 17, 18 is enlarged, thereby fixing the tubular body (a). An upper mold 10 is set with a gap above the tubular body 10 after the tubular body (a) is fixed. A resin material is injected into the gap in the periphery of the tubular body from an injection port 12, and accordingly a secondary molded tubular body is obtained.

Title: Mode coupler
Inventor: UENO SENSHIYU
IPC: H01P5/18
Filed: 1986-09-30
Abstract: PURPOSE:To suppress an unnecessary frequency for entering a subwaveguide from a main waveguide through a coupling hole, by setting the sub-waveguide to width by which the radio wave of the unnecessary frequency is cut off, in a mode coupler which has a circular main waveguide and a rectangular sub-waveguide, and has connected each propagation path by forming the coupling holes at an interval corresponding to a specific mode. CONSTITUTION:When for instance, the radio wave of 12GHz band is coupled even a little to a fundamental mode propagated to a sub-waveguide 12, through a coupling hole 13, an undesirable influence is exerted on the radiation characteristic of the 12GHz band. Therefore, the dimension of the sub-waveguide 12 is selected so that the 12GHz band is cur off, so that the radio wave of 12GHz band is not propagated in the sub-waveguide 12. Between width (a) of the sub- waveguide 12 and cut-off wavelength lambdac, in case of a TE10 mode, there is a relation of lambdac=2a. Accordingly, for instance, when a broadcast wave band is 11.7-12.2GHz, and a signal frequency for RF sensor 17.3GHz, the width (a) of the sub-waveguide 12 for obstructing the 12GHz band and allowing the 17GHz band to pass through is selected as 8.7mm<a<12.2mm in order to suppress an unnecessary frequency.
