Title: Print making device
Inventor: KAMEDA TAKANOBU
IPC: B41K1/02
Filed: 1995-08-23
Abstract: A compact print making device by which a desired imprint figure can be made easily in a short time. This print making device employs a resin seal face member, a part of which receives light having a wavelength within a predetermined range and thus is put into a state different from the state of the remaining part thereof and is adapted to have an uneven face formed by being acted upon by a predetermined fluid. The resin seal face member and an original picture representing an imprint figure are placed in such a manner that the original picture is placed just in back of the resin seal face member. Imprint figure information representing the imprint figure shown in the original picture is taken in by an information reading mechanism. A negative film making unit is driven according to the imprint figure information so as to produce a negative film. Then, the produced negative film is carried to an irradiating position. Subsequently, a light irradiating unit irradiates the resin seal face member with light through the negative film. Thereby, the state of a part, which corresponds to the imprint figure, of the resin seal face member or the remaining part thereof is changed. Finally, an uneven face thereof serving as a seal is formed by acting a predetermined fluid upon this resin seal face member.

Title: Water based beverages
Inventor: HUTCHISON KEITH GRAEME
IPC: A23L27/00
Filed: 1994-02-11
Abstract: A method is disclosed of preparing a beverage in the form of a dilute aqueous solution, suspension or dispersion of an encapsulated product. The capsule is added to a potable liquid, and the capsule material breaks down when submerged in the liquid to release its contents and itself dissolve. A primary advantage of providing the product in this way is that it can be confined within the capsule in liquid form, and can therefore disperse or dissolve in water more readily. Additionally, the capsule would normally sink to the bottom of the body of water before releasing its contents, thereby ensuring that the contents are released within the body of water, and not at the surface thereof.

Title: Echo canceler and method for learning for the same
Inventor: KAWAHARA TOSHIRO
IPC: H04B3/23
Filed: 1995-05-02
Abstract: The present invention relates to an echo canceler for training an echo path estimation without providing a hindrance to a speech. The echo canceler of the present invention includes a pseudo noise generator for generating a certain pseudo noise. This pseudo noise is forcibly supplied to a transmission line for transmitting a far-end talker's voice. Here, in the case where the far-end talker's transmitting speech level is faint or the far-end talker is in a speechless condition, a certain correlation is established between the pseudo noise and a signal of the transmission line for transmitting the near-end talker's voice. Based on such a correlation as just mentioned, a coefficient for generating an echo replica is calculated.    Therefore, a training for estimating an echo path is performed based on the pseudo noise and without depending on the far-end talker's voice, thereby generating an appropriate echo replica.
Patent CA-2162810-A1 (CA)
Title: Double needle button attacher
Inventor: KUNREUTHER STEVEN
IPC: A41H37/00
Filed: 1995-11-14
Abstract: Within a rigid housing cavity, freely moveably received members respectively support oppositely oriented spaced needles.          Double  "T" bar end type attachments situated between parallel connector bars are dispensed through the needles to attach buttons.          Depressing protrusions accessible from the exterior of the housing moves the needle support members to alter the needle spacing to accomodate buttons with a variety of thread hole spacings.   In order to reduce the peak force necessary to sever the attachments from the connector bars, the connector bars are severed from the ends of each attachment at slightly different times during the trigger stroke.  A triangular linkage associated with the trigger provides a mechanical advantage which increases at an increasing rate, transmitting maximum force towards the end of the stroke, as the filament connecting the "T" bars stretches around the portion of the button between the thread holes.   The ejector rods are moveably mounted such that alignment between each ejector rod and the associated needle is maintained regardless of changes in the relative position of the needles.

Patent CA-2167744-A1 (CA)
Inventor: ASH GERALD RICHARD
IPC: H04Q3/66
Filed: 1996-01-22
Abstract: A telecommunication network may be arranged in accord with the invention so that a change in provisioning data occurring at one element of the network is automatically supplied to the other elements of the network, thereby eliminating the need of having a network administration facility to communicate manually the change to the other network elements. For example, if a local central office switch is rehomed from a first toll switch to a second toll switch, then the first and second toll switches form messages respectively characterizing the rehome and then send the messages to each of the other network toll switches so that the other toll switches may update their respective routing and trunking data relating to the rehomed switch. The network is also arranged to implement a rule-based, end-to-end routing scheme which automatically selects a routing path from multiple candidates based on (a) class-of-service parameters and (b) availability of network capacity. The automatic selection of a routing path thus replaces the provisioning of routing data in the toll switches, which data was priorly needed to select the appropriate routing path.

IPC: G02F1/1343
Filed: 1994-09-02
Abstract: A light modulator comprises liquid crystal material (6) sandwiched between two substrates (2, 4) each bearing a set of electrodes, the sets crossing each other to define a matrix of pixels. A plurality of pixel areas having different switching thresholds is achieved by one or both of the sets of electrodes a set of primary electrode portions (10) separated from a set of secondary electrode portions (12) by an insulating layer (11), each secondary electrode portion (12) being connected to the corresponding primary electrode portion (10) by a plurality of connection members (13) extending through the layer (11). The structure presents a substantially flat surface to enable the liquid crystal layer (6) to be of uniform thickness and thus simplify the definition of the switching thresholds. In addition, the electrode material remains thin so that it offers less impedance to the passage of light. The secondary electrode portions (12) may be positioned so as to overlie the spaces (18) between the primary electrode portions (10), which may obviate the need for a black mask.
