Granted: 1998-06-21
Abstract: Fine metallic particles-containing fibers, characterized by having ion-exchangeable or ion-coordinable polar groups, having crosslinked structure, and containing fine particles of metals and/or hardly-soluble metallic salt, wherein the fine particles of a metal and/or a hardly-soluble metallic salt are those of one or more metals selected from the group consisting of Cu, Fe, Ni, Zn, Ag, etc., and/or one or more hardly-soluble metallic salts thereof selected from the group consisting of oxides, hydroxides, chlorides, etc., and dicarboxylates of such metals. A method for producing fine metallic particles-containing fibers, comprising applying metal ions or ions capable of bonding to metal ions to precipitate hardly-soluble metallic salts to crosslinked fibers having ion-exchangeable or ion-coordinated polar groups to thereby make the ions ion-exchanged or ion-coordinated with the polar groups, then adding a compound capable of precipitating a hardly-soluble metallic salt to the fibers to thereby make fine particles of a hardly-soluble metallic salt precipitated in the crosslinked fibers, and thereafter reducing them to thereby make fine particles of a metal and/or a hardly-soluble metallic salt precipitated in the crosslinked fibers.

Title: dynamic hibernation time in a computer system
Inventor: WILLIAM C HALLOWELL
IPC: G06F1/32
Filed: 1996-12-26
Granted: 1997-12-01
Abstract: A dynamic hibernation time apparatus monitors and ensures that battery packs in a computer system have sufficient energy capacity to sustain a proper saving of the hibernation file into the hard disk drive. The invention determines the memory size of the computer and adds the storage space needed to store the chip register contents to arrive at the determination of the hibernation file size. Next, the time necessary to save the hibernation file on the disk data storage device and the hibernation energy required to operate the disk data storage device to completely save the hibernation file are determined. When the battery capacity drops within a range of the previously computed hibernation energy, a warning message is generated at the user and the hibernation file is saved. The computer is shut down after the hibernation file has been properly saved. Thus, by determining the total memory size to be saved in the hibernation file, by determining the time and the energy required to completely store the hibernation file into the disk drive, and by sensing either the battery capacity or requesting that the smart battery sends an alarm to initiate the hibernation file saving process, the present invention ensures that sufficient energy exists in the battery packs to properly save the hibernation file onto the hard disk drive before system shut down occurs due to low battery capacity without wasting energy by determining the set point based on a maximum memory configuration.

Title: Multi-domain liquid-crystal display device
Inventor: VAN DE WITTE PETER
IPC: G09F9/30
Filed: 1997-12-11
Granted: 2003-03-11
Abstract: The invention relates to a multi-domain liquid-crystal display device comprising two substantially parallel substrates which are provided with an electrode layer and an orientation layer. A layer of a nematically ordered liquid-crystalline material comprising a chiral dopant is sandwiched between the substrates. The layer is structured in such a manner that the pixels of the layer are composed of at least two types of sub-pixels in which the twist senses of the liquid-crystalline material are mutually opposite. This construction in accordance with the invention is achieved by differentiating the composition of the chiral dopant in the different types of sub-pixels. This is attained by employing isomerizable chiral dopants and/or diffusion techniques in combination with local exposure of the liquid-crystal layer. The invention also provides methods of manufacturing such multi-domain liquid-crystal display devices. The multi-domain liquid-crystal display devices in accordance with the invention are easier to manufacture than display devices in which the orientation layers must be structured.

Abstract: A bottom bypass structure of a thermostat device includes a thermal-expansion object, a thermocouple element and a valve body. According to the temperature change of the circulating fluid in the passage, the thermal-expansion material hidden inside the outer shell with internal coolant circulation passages may expand or contract. The thermocouple element makes sliding elements to slide along with the volume change due to the expansion/contraction of the thermal-expansion material. The valve body is supported by valve axle rotatably in the circulation passage.  It has the following characteristics. The thermocouple element slides and turns the valve axle. The thermostat device uses the valve body opening and closing to control the flow rate of the circulation fluid.

Granted: 2000-06-01
Abstract: A method and apparatus for providing orthogonal spot beams, sectors, and picocells. The transmissions can be made orthogonal by using orthogonal auxiliary pilots and different Walsh traffic channels in adjacent areas. In accordance with the IS-95 standard, the pilot signal is covered with the 64-chip Walsh sequence zero. The 64-chip all zeros Walsh sequence can be designated as P and the 64-chip all one sequence can be designate as M. In the present invention, additional pilot signals can be provided by concatenating 64-chip all zeros P and all ones M sequences. Thus, for two pilot signals, pilot Walsh sequences of PP and PM can be used. For four pilot signals, pilot Walsh sequences of PPPP, PMPM. PPMM, and PMMP can be used. The present invention can be extended such that any required number of pilot Walsh sequences can be generated by substituting each bit in an K-bit Walsh sequence with the 64-chip all zeros P or all ones M sequence depending on the value of that bit.

Title: Automatic detection of HDTV video format
Inventor: WU SIU-WAI
IPC: H04N21/434
Filed: 1999-05-21
Granted: 2000-12-21
Abstract: A method and apparatus for automatically detecting the format of a high-definition television (HDTV) signal at a video encoder to allow proper encoding of the signal, including progressive and interlaced scan, and specific pixel and vertical line resolutions. The system is compatible with video standards such as the SMPTE and MPEG-2 standards. A video sample clock is determined by phase-locking clock pulses in a video signal to one of two or more available reference clocks. An SAV/EAV counter and pixel sample counter determine the horizontal resolution of the video, e.g., pixels per line. The system discriminates between 24 frames per second video and 30 frames per second video, and between a 720 line progressive scan signal and a 1080 line interlaced scan signal, for example. The system uses PLLs for each reference clock, where a lock range of the PLLs is narrow such that two PLLs will not lock at the same time for one input frequency. F bits in the video signal are used if required to distinguish progressive scan from interlaced scan.

Title: Actuator with approach pre-stroke and working stroke for operating a tool
Inventor: NOEL BOYER JEAN
IPC: C04B22/14
Filed: 1999-07-26
Granted: 2002-07-11
Abstract: An actuator (21) comprises a pre-stroke rod (29) which can be fixed to the tool body, for example soldering pliers. Thus by pressurizing the pre-stroke chamber (27) the working rod (34) for closing the pliers can be brought into an intermediate small opening position, the working piston (31) and the amplifying pistons (36, 37) remaining retracted in the actuator (21). Since the rod (29) can then be locked relative to the actuator body (21), pressurization of the working chamber (32) and the amplifying chambers (38, 40) will then cause the working rod to be extracted (34) and the soldering pliers to be closed without any recoil from the actuator body.
