A method of searching a specified band of frequencies for a plurality of active signal frequency in a scanning receiver is disclosed. In the preferred embodiment, a range of channel memory storage locations are specified and a controller in the scanning receiver repetitively scans the range of frequencies for active signal frequencies and stores a number corresponding to each active signal frequency in one of the storage locations. Upon filling all of the specified storage locations, the search and store operation is terminated.

The powered ratchet wrench 10 is constructed of several components. A throttle lever 20 controls the air flow to a rotary air motor 30. The rotary output of the motor is transmitted to the hammer assembly 40 of an impact clutch mechanism. A spring 50 biases an anvil shaft 60 into association with the hammer assembly 40. The anvil can be directly driven by the motor through the hammer assembly or can be driven intermittently by a series of rotational impacts from the hammer assembly. The rotation of the anvil shaft causes the reversible ratchet mechanism 70 to rotate in the desired direction, thus tightening or removing a threaded fastener. Only a small reaction force is transmitted by the tool to the operator once the fastener is tightened.

A fragrant fibrous structure, such as fabrics, apparels or the like, provided with microcapsules encapsulating a perfume and a resinous binder, preferably a silicone resin in a weight ratio of 2/1 to 1/5, an add-on amount in the aggregate of said microcapsules and resinous binder being 0.3.about.7.0% based on the weight of the portion to which said microcapsules and resinous binder are adhered, of the fibrous structure. The process for preparing the above fibrous structures comprises applying a treating liquid comprising microcapsules composed of an external wall of a formaldehyde based resin enclosing a perfume and a resinous binder, preferably a low temperature reactive organopolysiloxane prepolymer emulsion, preferably together with a pressure absorbing agent, to at least a part of a fibrous structure and then drying the fibrous structure at a temperature of less than 150.degree. C. to fix said microcapsules on fiber surfaces of the fibrous structure.
摘要:
A device for checking positional accuracy is disclosed which precisely checks the accuracy of the mounting position of a plurality of magnetic heads mounted on a rotary disk along the edge thereof. The device includes a laser which projects a laser beam in a direction at a predetermined angle with respect to the rotary disk. The laser beam is successively scattered by head gaps of the magnetic heads. A photosensor converts the scattered light components into photoelectric signals each containing two photoelectric signal components. The two photoelectric signal components of each of the photoelectric signals are differentially amplified by an operational amplifier. The operational amplifier produces successive differential signals which are supplied to a zero-crossing detector. The accuracy of the mounting position of the magnetic heads is then checked based on the interval between adjacent detected zero crossings.

The antenna unit 100 includes a first antenna 10 positioned so as to face in the direction of gravity when the unit is oriented transversely, and a second antenna 20 positioned so as to face in the direction of gravity when the unit is oriented longitudinally. Based on the output of a sensor 50 that detects whether the antenna unit 100 is oriented transversely or oriented longitudinally, a switch controller 42 performs switching of an RF switch 30 so that the first antenna is used for reception or transmission of vertically polarized waves when the antenna unit 100 is oriented transversely, and the second antenna is used for reception or transmission of vertically polarized waves when the antenna unit 100 is oriented longitudinally.
摘要:
In the region in which a coil and a connector are provided, the leakage of a fluid to which coil and connector is prevented by a seal member, a passage extending from the seal member to a position in the vicinity of a terminal of the connector is formed. At the time of completion of the production of a solenoid valve assembly, an air-tightness test on the seal member can be conducted directly through the passage, so that the detection of damage to the seal member, the detection of bite into the seal member, the detection of a defect of the seal member and so on can be carried out at the time of completion of the production of the mentioned assembly. Namely, the detection of the sealability of the seal member is rendered possible.
