Patent CA-2005148-A1 (CA)
IPC: B29D30/32
Filed: 1989-12-11
Abstract: A method of bending back a tire component, comprising a step in which the diameters of a pair of cylindrical bodies, whose diameters can be increased and decreased, are decreased to a minimum value to hold beads by the bodies, respectively, and the beads are set in prescribed positions on the component wound on a forming drum; a step in which the diameters of the bodies are increased to an intermediate value and the bladders of the drum are inflated so that the component is pinch-held at both the side edges thereof by the bladders and the bodies; a step in which the bodies are moved to positions located nearly outside the beads in the radial directions of the bodies, so that both the side edges of the component are moved outward in the radial directions of the bodies as the component remains in pressure contact with the beads near the side edges; and a step in which the diameters of the bodies are  increased to a maximum value and the bodies are thereafter moved toward the longitudinally central portion of the drum so that the component is bent back at both the side edges thereof around the beads by the bodies, the bladders and the body of the drum.

Patent CA-2016400-A1 (CA)
Title: Dual bus microcomputer system with programmable control of lock function
Inventor: BEGUN RALPH M
IPC: G06F12/08
Filed: 1990-05-09
Abstract: A dual bus microcomputer system including a cache subsystem improves performance under certain circumstances by allowing programmable control over the LOCK function. More particularly, additional logic is coupled between the LOCK output of the CPU and the LOCK input of the cache controller.  A control bit from an I/O port is a second input to the additional logic.  With the control bit in one state, the logic allows the LOCK input to follow the LOCK output.  In the other state of the control bit, the LOCK input is disabled regardless of the state of the LOCK output.
Patent CA-2016558-A1 (CA)
Inventor: WONG ALAN
IPC: G11B7/00
Filed: 1990-05-11
Abstract: The present invention is concerned with an optical disk reproducing apparatus for reproducing digital data from an optical disk, such as an audio compact disk and, above all, with such apparatus in which a continuous playback output may be produced even when track jump should occur due to vibrations or the like. With the optical disk reproducing apparatus according to the present invention, digital data detected from an optical disk are sequentially written in a RAM for subsequent reading so that data stored in the RAM continue to be read even on the occurrence of the track jump to provide a continuous playback output. On the other hand, the optical disk is reproduced at an increased speed for a predetermined time period after the light spot irradiating the optical disk resets to its original position from track jump to replenish digital data to the RAM.

Filed: 1991-01-18
Abstract: TITLE OF THE INVENTION            METHOD AND APPARATUS FOR CUTTING A WORK PIECE HAVING A SURFACE COATING            ABSTRACT OF THE DISCLOSURE     Flat multi-layered work pieces, such as panels with a decora-tive or finish surface coating, are prescored and cut through by the same saw blade to avoid damage to the surface coating.          For this purpose a circular saw is guided along a guide rail and its saw blade is adjustable to a prescoring depth and to at least one lateral prescoring position to make a first pre-scoring cut only through the cover layer in a sawing direc-tion in synchronism with the blade rotation direction.  If necessary, the blade is adjusted to a second lateral prescor-ing position to make a second prescoring cut only through the cover layer in a cutting direction in synchronism with the blade rotation.  Finally, the saw blade is adjusted to its full cutting depth and to a lateral position between the two prescoring positions and a full cut is made through the entire work piece in a sawing direction counter to the rota-tion direction of the saw blade.  A circular saw for carrying out the foregoing method has a single saw blade, stop ele-ments, and adjustment mechanisms for adjusting the single saw blade into the various necessary positions.  The prescor-ing avoids damage to the surface coating even if it is brittle. 2562/ar                        -1-
Patent CA-2035648-A1 (CA)
Title: Integrated services digital network multimedia communications system
Inventor: ANZAI MASAKI
IPC: H04N21/236
Filed: 1991-02-04
Abstract: In a multimedia communication terminal, a CPU generates a mode identifier and subsequently a switching signal in response to a command input as well as in response to receipt of an incoming mode identifier.  Frame synchronization circuitry multiplexes an outgoing digital video signal from a video codec with the mode identifier into an outgoing composite video signal, and demultiplexes an incoming composite video signal from a distant terminal into a mode identifier and a digital video signal. In response to the switching signal, the terminal is switched from video to data communication mode by coupling a LAPB (link access procedure balanced) controller to an ISDN (integrated services digital network) interface so that the CPU can exchange computer data and/or a mode identifier with the distant terminal without frame sync.  Due to the elimination of frame sync, the terminal can access a database through the ISDN network.  The terminal is switched from data to video communication mode by coupling the LAPB controller to the interface via the frame synchronization circuitry so that the video codec exchanges composite video signals with the distant terminal.  During the video mode, the synchronization circuitry supplies an incoming data mode identifier to the CPU via the LAPB controller and the CPU supplies an outgoing data mode identifier to the synchronization circuitry via the LAPB controller.
