Abstract: The present invention is directed to a frame that is placed at an opening portion in a partition provided in houses and the like, and specifically an adjustable frame comprising a plurality of frame adjustable fasteners including: a fixing member including an external thread member having a cylindrical manner for being incorporated at a partition side of an opening portion in a partition provided in houses and the like, and a base member for rotatably supporting said external thread member; and an internal thread member for being rotatably engaged with said external thread member and for installed in a frame body.   The adjustable frame allows the external thread member to be turned, thereby adjusting its length, capable of fixing to the opening portion of the partition. Further, if necessary, the adjustable frame may be comprised of a pair of frame members having the width where a first frame member and a second frame member overlap in part in a thickness direction of the partition (wall thickness). It is provided a surface member so arranged that the end face of said second frame member that overlaps the surface of said first frame member and the edge surface thereof are covered, and a clip engaging member for allowing said first frame member to be brought into contact with the bark surface of said second frame member is also provided. In the above-mentioned arrangement, therefore, the adjustable frame can be adapted for the wall thickness of the opening portion. The adjustable frame can. be realized in a manner that the spacing between the partition and the frame can be readily adjusted by turning the external thread member at the time of installation of the frame at the opening portion of the partition provided in houses and the like, and can be adapted for different levels of the wall thickness by a separated frame member in a wall thickness direction of the opening portion.

Title: Precision liquid injection system
Inventor: KNECHT WILLIAM G L
IPC: F04B9/14
Filed: 1998-11-03
Granted: 2008-06-03
Abstract: There is provided an injector for use in injecting a liquid into a pressurized system such as an air conditioning system. The injector has a tubular spindle having a longitudinal axis, an open end, and an opposing partially closed end. The spindle open end and spindle closed end define a cylindrical bore along the longitudinal axis of the spindle. A cylindrical piston within the spindle bore is axially aligned with the longitudinal axis of the spindle. There are sealing means such as O-ring seals between the spindle and the piston. The spindle, piston and sealing means define a chamber between the piston and the spindle closed end within the bore. A  tubular driver sleeve has a longitudinal axis, an open end and an opposing closed end. The driver sleeve has threads around an interior surface of the sleeve and the spindle has compatible threads around an exterior surface of the spindle such that rotation of the driver sleeve in one direction screws the driver sleeve towards the spindle closed end. This causes the piston to move towards the spindle closed end and exert pressure on the chamber.

Abstract: A translation is performed by using a programmable hashing technique on an input number to generate a hashed number (408). A subset (410) of the hashed number bits are used to index a first hash table (420). In first hash table locations (426) where a hash collision does not occur, the first hash table entry (426) contains an index (for IDX) into an output (438) table which contains the desired translated output number (436). In first hash table locations where a hash collision occurs (424), the first hash table entry (494) contains a pointer (NTI) to a first resolution table area in a second hash table. The first resolution table area contains entries which are indexed by additional bits selected from the hashed number in accordance with a mask field in the first hash table location. If collisions occur in the resolution table a new resolution table is created and the process is repeated. The resolution process thus proceeds in stages until all input numbers have been translated.

Abstract: A method for increasing a channel efficiency and saving a transmission power by controlling outputs of a dedicated control channel and a pilot channel when data transmission is discontinued temporarily during the data communication in a mobile communication system. The mobile communication system includes an active state (117) in which user data is transmitted through a dedicated traffic channel and a control message is transmitted through a dedicated control channel when there exists information to transmit. A base station of the mobile communication system comprises the steps of transitioning to a first control hold state for releasing the dedicated traffic channel and maintaining the dedicated control channel, when there is no data to transmit for a first set time in the active state; and transitioning to a second control hold state for logically connecting the dedicated control channel to control an output of a transmission signal, when there is no data to transmit for a second set time in the first control hold state. Here, the data to transmit is user data and control data. Further, the logical connection in the second control hold state discontinues, in a state where the channel resource is logically assigned, a transmission output of a corresponding channel.

Abstract: A structure for fitting a rotary displacement sensor for detecting the rota ry displacement of rotary shafts, such as kingpins provided in vehicles, aiming at preventing the degradation of the durability and damage due to the force exerted on the input shaft of the rotary displacement sensor in the radial direction and achieving a high level of measurement precision by eliminating the play with the rotary shaft. 'The rotary displacement sensor is fixed to a member supporting the rotary shaft rotatably, in such a way that the central axis of the input shaft is substantially aligned with t he central axis of the rotary shaft. The input shaft and the rotary shaft are linked by rotatio n transmitting means. The rotation transmitting means permits by elastic deformation misalignment of the central axis of the input shaft with the central axis of the rotary shaf t and regulates the relative rotation of the input shaft to the rotary shaft. Even if any misalignment occurs between the central axis of the input shaft and the central axis of the rota ry shaft, the force exerted from the rotary shaft on the input shaft in the radial directi on is absorbed and relaxed, and the rotation of the rotary shaft is transmitted as it is to the input shaft.
