Patent CA-2233110-A1 (CA)
Inventor: SIEGFRIED DAVID
IPC: G03F7/004
Filed: 1998-03-23
Abstract: A negative-acting color proofing element comprising, sequentially, (i) a strippable, transparent cover sheet; (ii) a crosslinked layer, which comprises a polymer having phenolic groups; (iii) a color layer, which comprises an organic binder, a polymerizable monomer, a colorant, and an optional photoinitiator, (iv) a photoadhering layer, which comprises a polymerizable component having at least one ethylenically unsaturated group; a polymer comprising polyvinyl acetal and polyvinyl alcohol segments, having from about 1 to about 40 weight % polyvinyl alcohol content; and an optional photoinitiator, wherein least one of either the color layer or the photoadhering layer contains a photoinitiator; (v) a thermoplastic adhesive layer; and (vii) a receiver sheet. Preferably the polymerizable component and photoinitiator diffuse into the color layer during assembly of the element. An image is produced by laminating the photosensitive element to a receiver sheet; imagewise exposing the color layer and the photoadhering layer to actinic radiation through the transparent cover and crosslinked phenolic layer; peeling apart the receiver sheet and the transparent cover sheet, leaving exposed areas of the color layer attached to the receiver sheet via the photoadhering layer and adhesive layer and unexposed areas being removed with the cover sheet and the crosslinked phenolic layer, thereby forming a colored negative image on the receiver sheet. Preferably these image producing steps are repeated at least once wherein another photosensitive element having a different colorant is transferred via its photoadhering and adhesive layers to the negative image previously produced on the receiver sheet.

Title: Portable radio communication device
Inventor: SUGURO AKIHIRO
IPC: H04B1/38
Filed: 1997-04-14
Abstract: A small-sized flat antenna mounted on a portable radio communication device is available for a narrow bandwidth, and the resonance frequency of the flat antenna varies due to interference between the flat antenna and surrounding dielectrics such as a housing and a human body.        As a result, the transmission efficiency and reception sensitivity of the antenna have been impaired. A communicating section (constructed of a coaxial line or a microstrip line) is arranged in a portable radio communication device having a circularly polarized antenna for satellite communication, so that an appropriate distance is provided not only between a housing of the portable radio communication device and the antenna but also between a human body and the antenna.

Patent CA-2248617-A1 (CA)
Inventor: OHIRO NORITAKA
IPC: B60J7/057
Filed: 1997-05-29
Abstract: A rotational speed sensor (29) generates pulses at a cycle corresponding to a speed of a motor, and a pulse cycle calculating unit (32) calculates the cycle of the pulses. An interposition presuming unit (36) calculates load on the motor on the basis of the cycle of the pulses and presumes interposition of a foreign matter when the load exceeds a predetermined threshold. When interposition of a foreign matter is presumed, a drive control unit (40) stops driving of the motor and then reversely controls the motor to release the foreign matter interposed. Meanwhile, a door opening and closing detection unit (34) detects door opening and closing actions, which constitute one of causes for distrubance, and an inhibition control unit (38) inhibits presumption of interposition for a predetermined period of time after the door is opened or closed. Accordingly, an erroneous judgement of interposition of a foreign matter due to opening or closing of the door is prevented.
