Inventor: MATSUNAGA HIROKAZU
IPC: B32B17/06
Filed: 1998-04-09
Abstract: A glass paste containing pigment particles of silicon tetraboride each covered with a silica glass film (silica glass layer) having a silicon dioxide content higher than that of the glass structure present at the interface with the pigment particle and a predetermined thickness. In the glass film formed by applying this glass paste to the surface of a substrate and firing it, a silica glass film (silica glass layer) which is relatively lowered in the reactivity with the pigment particle by virtue of its silicon dioxide content higher than that of the glass structure is formed at the interface between each pigment particle and the glass structure. The use of the glass paste effectively prevents a high-radiation glass film wherein a high-radiation pigment is dispersed in a glass structure from undergoing interfacial reactions between the pigment and the glass structure during production and use thereof.

Abstract: To provide a unit for adjusting humidification capable of improving inconveniences that may otherwise be caused to occur due to damages, while sustaining the humidifying ability and other performance that are to be originally achieved by the humidification adjusting unit. Around the outer surface of the exothermic member (13) are wound multiple hollow fibers (14) each having a minute diameter and having a peripheral wall with minute openings each being large enough to allow water vapor to permeate therethrough yet small enough to fail to permeate water therethrough, and the multiple hollow fibers (14) and the exothermic member (13) are inserted tightly into an extendable mesh cover tube (15) in engagement therewith. In order to perform humidification, water to be supplied to the multiple hollow fibers (14) is warmed by the exothermic member (13) to generate water vapors.  Even if the multiple hollow fibers (14) would be broken or damaged, the water to be leaked from the multiple hollow fibers can be made extremely small in volume by taking advantage of the minuteness of each of the multiple hollow fibers (14), thereby failing to cause to occur any substantial problems that may otherwise cause inconveniences due to the leakage of water.

Title: Highly bandwidth-efficient communications
Inventor: GIBBONS DAVID
IPC: H04B1/7107
Filed: 1998-02-24
Abstract: A discret multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.

Inventor: SAYER JOHN
IPC: A01B59/06
Filed: 1999-10-22
Abstract: The invention relates to an assembly with a lower steering arm having a strut 1 and an attaching end 16. To achieve a cost-effective design while at the same time reducing the play between the attaching end 16 and the end of the strut 1 received therein, the attaching end 16 consists of a base member 18 and a cover 19. In the base member 18, there is supported the blocking pawl 34. The cover 19 is welded to the base member 18 and comprises a stop face 30 for the end face 10 of the strut 1, so that any tolerances in the region of the base member 18 provided in the form of a forging do not affect the position of the stop face 30. The latter can be aligned when connecting the base member 18 and the cover 19.      Because of its setting contour, the actuating lever 43 can be used for both the right-hand and the left-hand lower steering arm.
