Title: Dry control valve and air conditioner
Inventor: NAKAHARA SEIICHI
IPC: F25B29/00
Filed: 2001-12-20
Abstract: <P>PROBLEM TO BE SOLVED: To save on resources, energy and a space by dispensing with a electrically driving part in a dry control valve in an air conditioner.  <P>SOLUTION: The dry control valve 1 has a valve element 12 in a valve chamber R and freely slides the valve element 12 between a first port 11a and a second port 11b. A spring 13 energizes the valve element 12 to be separated from a valve seat 14. A hydraulic force of refrigerant to the valve element 12 is controlled by operation control of a compressor 6 or the passage selection by a passage selector valve 5. A first port 11a is set to a high-pressure side, the valve element 12 is seated on the valve seat 14, thereby performing dehumidification operation. When the first port 11a is set to the high pressure side, the valve element 12 can be retained in an intermediate position by a guide groove 12a and a pin 17, thereby performing cooling operation. When the second port 11b is set to a high-pressure side, the valve element 12 is separated from the valve seat 14, thereby performing heating operation. Filters 16 disposed in the upper/lower parts of a throttle 15 provide sound attenuation effects.  <P>COPYRIGHT: (C)2003,JPO

IPC: G06T1/00
Filed: 2001-12-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for determining an evaluation cross section capable of automatically determining at which evaluation cross section a work is to be evaluated without the need for a workman's skill.  <P>SOLUTION: Measurement data which expresses the measured shape of the work by a group of points, and design data which expresses the ideal design shape of the work, are inputted (S1) and are converted into measurement data which expresses the measured shape by triangular planes obtained by connecting the group of points (S2). Error regions are extracted on the basis of converted measurement data (S3). In the case that the distance between extracted error regions is shorter than a predetermined value in comparison (S4: YES), the error regions are composed (S5). When comparisons of the distances between all the error regions are completed (S6: YES), it is determined which evaluation cross section obtained by cutting the error regions at which part is to be evaluated (S7) to perform evaluation on the evaluation cross section (S8). The results of evaluation are stored (S9). When evaluations on all the evaluation cross sections are completed (S10: YES), the processing for determining evaluation cross sections is completed.  <P>COPYRIGHT: (C)2003,JPO

IPC: G09C1/00
Filed: 2000-06-09
Abstract: A technique which implements a primitive for computing, e.g., a checksum. Specifically, this primitive replaces a mod(M) operation with a series of simple elementary register operations. These operations include mod 2<n> multiplications, order manipulations (e.g., byte or word swaps), and additions - all of which are extremely simple to implement and require very few processing cycles to execute. Hence, use of our technique can significantly reduce the processing time to compute various cryptographic parameters, such as, e.g., a message authentication code (MAC), or to implement a stream cipher, over that conventionally required. This technique has both invertible and non-invertible variants. <IMAGE>

IPC: G08G1/16
Filed: 2000-06-21
Abstract: The invention relates to a road traffic routing system for dangerous routes, especially tunnels. Said routing system comprises light signals (8) that are arranged at approximately equal intervals along a roadway (2). It also encompasses sensor devices for detecting the state of vehicles (26, 30) that are arranged at approximately equal intervals along the roadway and a control device (24) that is linked with said light signals and said sensor devices. If the sensor device detects a vehicle (30) that might have problems, the light signals (sector A) that are located behind the problematic vehicle with respect to its direction of travel are switched to a state in which they indicate the blockage of the road. If danger is imminent, the light signals can display turn-around arrows that signal the drivers to turn around and leave the dangerous route.

IPC: H04L29/06
Filed: 2000-06-27
Abstract: A received data stream is formed into a stream of packets, each packet comprising a payload section of data and an overhead section. In forming the packets, a template overhead section is created for use by the stream of packets and this template is applied to the data to form the packets. This avoids the need to individually pass packets through a routing stack, thus reducing the processing demands on the processor which constructs the data packets and reducing the transmission delay experienced by data. The template overhead section can be formed by sending a packet through a routing stack. Another aspect describes apparatus for processing packets where a first processor processes signalling packets and a second processor processes real-time data packets. The first processor can be, used to create the template overhead section before passing the template information to the second processor where it can be used in forming the real-time data packets.

Abstract: A plasmatron operating efficiently within a wider range of gas flows and capable of sustaining a stable arc voltage. The plasmatron generates an electric arc at the tip of a cathode electrode and transfers the arc along an arc chamber and into the bore of an anode electrode located at the downstream end of the arc chamber. A plurality of arc root attachment surfaces are defined on an inner surface of the anode by a plurality of ring members, causing the electric arc to attach with its root to the arc root attachment surfaces and therefore the axial movement of the arc root is confined substantially to the anode electrode. The arc voltage variations are limited and controlled substantially by the arc root movement between two adjacent arc root attachment surfaces. When used within a plasma-spraying torch, the plasma stream generated by the plasmatron has improved characteristics and induces improved plasma spray coatings.

Abstract: The inventive conduit holder is used to mutually fix at least two conduits extending side by side. The holder consists of a lower part (1) with one or several retaining shells (3,3') which are used to receive said conduits (5); an upper part (2) with corresponding counter shells (4,4') which are used to enclose the conduits (5) and locking means connecting the upper part (2) to the lower part (1). In order to prevent axial displacement or torsion of the inserted conduit, a bore hole is provided (13) and arranged between two adjacent retaining shells (3, 3', 4, 4'), running perpendicular to the center axis thereof. The diameter of the bore hole (13) is dimensioned in such a way that the cylindrical surface of said bore hole cuts into the retaining shells (3, 3',4, 4') . A pin (14) is also provided, whereby said pin is driven into  the bore hole (13) when the conduits are enclosed (5) and the upper part (2) is connected to the lower part (1). The wall of the conduit (15) is deformed when the pin (14) is driven inwards by virtue of the fact that the retaining shells are only slightly penetrated by the bore hole (13). Said deformation can be permanent or elastic according to the type of material used for said conduit and causes the conduits (5) to be fixed in an inserted position.

The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by a plurality of interconnecting members placed on the stent in a colinear arrangement such as to create at least one continuous spine which extends along the length of the stent. The invention is also directed to a stent delivery system for implantation of a stent in a vessel which includes an outer tubular member having a restraining sheath and an inner tubular member having a distal end which has a compressed stent mounted thereto. The proximal end of the inner tubular member is connected to a housing assembly which prevents the inner tubular member from moving when the outer tubular member is retracted to deploy the stent. The proximal end of the outer tubular member is attached to a pull-back handle which is slidably mounted on the base of the housing assembly. When the pull-back handle is retracted, the restraining sheath is retracted to deploy the sheath, while the inner tubular member remains stationary.
