Filed: 1991-08-22
Granted: 2001-08-14
Abstract: Video signal recording apparatus wherein a video signal is processed, such as in time division multiplexed format. A burst clock signal of frequency f b is generated for recovering the video signal during a subsequent reproduction operation; and this burst clock signal is added to a DC level portion that is present in the processed video signal, resulting in a combined signal. The combined signal is frequency modulated and recorded on a record medium. Assuming that the DC level of the processed video signal is represented by a modulating frequency f a, if f a ~~f b, then ~2f a - mf b - f b~ ~ 0.15f b; and if f a ~ ~ f b, then ~mf b - 2f a - f b~ ~ 0.15f b.

Granted: 1998-09-15
Abstract: An  eccentric  roller  control  apparatus  is intended to eliminate the adverse effect of the eccentric upper and lower back-up rollers against a product profile with high precision.   The rolling weight sensors 7W, 7D sense each rolling weight of a working side and a driving side.   The rotary angles of the upper back-up roller 4T and  lower  back-up  roller  4B are  sensed by  the  angle sensors 8T, 8B.  The roller eccentricity sensor 14 serves to derive each of the amplitudes ATWn, BTWn, ABWn, BBWn, ATDn, BTDn, ABDn and BBDn as each roller eccentricity of the working  side  and  the  driving  side,  based on  the sensed rolling weights PW, PD and the rotary angles .theta.T and .theta.B.   Then, the depression operating unit 15W serves to derive the depression of the working side and add the derived value to the depressor control device 6W.   The depression  operating  unit  15D  serves  to  derive  the depression of the driving side and add the derived value to the depressor control device 6D.

Title: Process for the vapor-phase thermal cracking of dicyclopentadiene and a process for the manufacture of high purity dicyclopentadiene
Inventor: KAWAKITA MASARU
IPC: C07C13/15
Filed: 1992-04-15
Granted: 1998-03-31
Abstract: Recently, as a process for manufacturing cyclopentadiene resin-shaped articles, an attention has been given to reaction injection molding (RIM).  To conduct RIM, it is necessary to use high purity dicyclopentadiene (DCPD) as the raw material. Vapor-phase thermal cracking of DCPD is usually used as a step of process for manufacturing high purity DCPD.  Hithertofore, when coducting thermal cracking of DCPD, coke formation within cracking tubes is the most serious and troublesome problem.  A vapor-phase thermal cracking process for resolving the problem by a very simple procedure is described herein.  Further, a process for manufacturing high purity DCPD suitable as a raw material  for  use in RIM utilizing  the vapor-phase thermal cracking process just mentioned above is also described.

Title: Acd multiflow network call distribution
Inventor: OTTO MARY RITA
IPC: H04Q3/66
Filed: 1992-05-20
Granted: 1996-02-06
Abstract: This invention relates to apparatus and methods for sharing traffic among a plurality of ACD sites serving a customer. Each ACD site has a main queue for storing incoming calls to that ACD, and a group of overflow queues forstoring calls rerouted from one of the other ACD sites. Before rerouting a call to an alternate site, the overflow queue for that site is checked; if it has an excessive number of entries, calls will not be rerouted to that alternate site. If one of the ACD sites is not appropriately equipped with overflow queues for different sites and an appropriate program for steering calls, that ACD site can route its overflow traffic via one of the ACD sites, designated as a mother node, for distributing overflowfrom the one site to others.

The first plurality of filaments (18) have a modulus of elas-ticity which permits flexing of the blanket (12) during movement of the blanket (12) through the extended nip press (10). The base (16) also includes a second plurality of filaments (20-24) woven together with the first plurality of filaments (18) and disposed in a cross-machine direction (CD). The second plurality of filaments (20-24) have a modulus of elasticity which is higher than the modulus of elasticity of the first plurality of filaments (18) for inhibiting flexing of the blanket (12) in a cross-machine direction (CD). Thermo-setting resin (26) is applied to the base (16) such that the resin (26) is reinforced by the base (16). The resin (26) defines a plurality of vents (28 - 35) for permitting the escape of water in the liquid and vapor phase away from the extended nip press (10) during use thereof.  The second plurality of filaments (20 - 24) prevent collapse of the vents (28 - 35) during use of the extended nip press (10) due to the higher modulus of elasticity.

Abstract: A theme of the present invention is to provide an optical mirror and an optical device using the same in which the mirror is capable of reflecting a light beam having a plurality of wavelengths with the phase matching condition required for nonlinear optical materials being satisfied, so that a decrease in efficiency due to the phase difference does not generate even if harmonic generation, optical mixing or the like is performed, thereby being capable of improving conversion efficiency. The optical mirror wherein a plurality of reflection films, e.g., reflection multilayer films 2 and 3, are formed on an edge surface of a transparent substrate (1), each of which films corresponds to each wavelength of a light beam having a plurality of wavelengths to reflect selectively one of said plurality of wavelengths, comprises a phase difference adjusting layer 4 formed between two reflection films 2 and 3 reflecting light beams having different wavelengths, said adjusting layer eliminating phase difference between a phase of the light beam reflected by 1, 2 or 3 of the reflection films and a phase of the light beam reflected by the other 3 or 2 of the reflection films. This optical mirror can be suitably applied to second harmonic generation, optical mixing, optical parametric generation and the like because it is capable of reflecting with the phase matching condition required for the nonlinear optical materials being satisfied and has high conversion efficiency.
