Title: Rds receiver
Inventor: INAGO KAZUHITO
IPC: H03J5/00
Filed: 1992-11-27
Abstract: PURPOSE:To allow the RDS receiver to select an excellent reception station regardless of the presence of disturbing noise by discriminating the presence of disturbance when no RDS is acquired and an S meter output has a prescribed output or over and setting the S meter output to be zero thereby executing the AF switching operation. CONSTITUTION:When RDS data are inputted to a CPU 4, an RDS flag is set and then the presence of RDS is discriminated. Then the CPU 4 discriminates whether or not the RDS data are acquired based on the RDS flag and also discriminates whether or not the S meter indicates a value larger than a true electric field at which the RSD data are able to be acquired. It is decided that a disturbance station exists, when the RDS data is not obtained and the S meter indicates a value layer than a true electric field at which the RSD data are able to be acquired. In this case, the S meter is regarded forcibly to be 0 and the AF switching operation is executed. Furthermore, when the presence of a disturbing station is discriminated, the CPU 4 gives a special mark to the frequency in an AF list to place lower priority of switching to the station and to select an excellent station.

Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent the intrusion of foreign matter into a pump by covering the tank-shaped case main body storing sufficient make-up water when sucked into the pump and having an air chamber at the upper part, setting a filter main body freely detachably in the middle of a case having a lid provided with an air vent and furnishing an outlet at the lower part. SOLUTION: When ther is no water in a suction pump in the initial suction stage of the pump, a make-up water 22 in a case 21 is sucked into the pump, and the pump is started. The water is sucked into a case main body 24 from an inlet 27 and filtered by filter main body 26 to remove the foreign matter and solid in the water. The water freed from the foreign matter and solid is sucked into the pump from an outlet 28 and supplied to a specified waste water treating stage. In this case, the pressure in an air chamber 23 is made negative while the pump is operated. When the filter main body 26 is filled up with the foreign matter and solid, an air vent 29 is opened to return the chamber 23 to atmospheric pressure, a lid 25 is lifted, and the filter main body 26 is cleaned.

Title: Motor-driven blower
Inventor: AKOSHIMA KAZUHIRO
IPC: H02K3/50
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce resistance of a rotor coil, to reduce electric resistance by reducing a copper loss, and to improve efficiency of an electric blower by constituting the rotor coil of a rotor iron core of a commutator electric motor out of the specific number of electric wires per unit coil. SOLUTION: When a surface recess/projection of a coil becomes too large by thickening of the coil of a rotor and a stator arranged in an air duct of an air flow from an air blower, electric resitance and a windage loss increase. Thus, a rotor coil 6b wound round respective magnetic poles of a rotor iron core 6a of a commutator electric motor 1 is constituted of two or more electric wires per single coil. Thus, even if the respective electric wires are fine lines, the cross-sectional area is substantially increased by pluralization to obtain a copper loss reducing effect equal to or larger than a heavy line. Actually, a dead space between coils is reduced by line thinning, and a space factor is increased more than the heavy line, so that a copper loss can be reduced.  A recess/projection of a coil surface is reduced due to a fine line, and ventilation resistance can be reeuced, so that efficiency of a motor-drivn blower 1 can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide the sufficient rolling force by providing a flow control means for restricting the flow of the hydraulic oil moving inside of a bypass circuit for communicating a bottom side oil chamber and a rod side oil chamber of a boom cylinder with each other at the time of turning an arm. SOLUTION: When a float changeover switch 44 is operated, electromagnetic popped switching valves 39a, 39b are switched from an oil passage cutting position to an oil passage opening position at the same time. When the arm is operated so as to be turned forward and backward, a boom cylinder 17 is shrunken and extended so that the hydraulic oil is moved in the inside of a bypass pipeline connected between a bottom side oil chamber 25 and a rod side oil chamber 26, but since the flow of the hydraulic oil is throttled by each variable throttle parts 40a, 40b, telescopic movement of the boom cylinder 11, namely, hoisting and turning of the boom do not become in the free floating condition.  Consequently, floating condition of the boom is limited and a front part of a lower traveling body tends to be floated from a ground at the time of turning the arm, a part of the weight of a car body is applied to a roller so as to show the sufficient rolling force.
