Title: A signal processing circuit for a solid-state imaging apparatus
Inventor: ASAIDA TAKASHI
IPC: H04N9/04
Filed: 1990-10-03
Granted: 2000-12-12
Abstract: A signal processing circuit for a solid-state imaging apparatus in which an imaging output signal from each solid-state image sensor of an imaging section making use of spatial offsetting is digitized to form a detail signal for image enhancement by digital signal processing. A first delay circuit having at least one delay unit with a delay time approximately equal to one horizontal scanning period provides the above mentioned delay time to a green color imaging signal of the digital output signal obtained by digitizing image output signals read from the solid-state image sensors. The signal synthesis is then performed in a first synthesis circuit to limit the band of the green color imaging signal in the perpendicular imaging signal. A second delay circuit having at least one digital delay unit having a delay time about equal to one horizontal scanning period provides the above mentioned delay time to one of the red or blue color imaging signals or combined red and blue color imaging signals of the above mentioned digital output signal. Signal synthesis is then performed by a second synthesis unit to limit the band of the red or blue color imaging signal or the combined red and blue color imaging signals in the perpendicular direction. Equal amounts of the first and second synthesis signals are summed together in a summation unit so as to be outputted as the horizontal detail signal via digital filer unit.

Title: Antitheft device
Inventor: HARA IWAO
IPC: G08B13/24
Filed: 1991-12-05
Granted: 1995-12-05
Abstract: An antitheft device of the type having a body unit to be attached to an article displayed in a shop for protecting the article against shoplifting.  The device includes a transmitter for radiating an AC signal to a particular area, and the body unit which is adapted to receive a signal from the transmitter.  The body unit comprises an alarm generator, and a receiving circuit operative to actuate the alarm generator in response to the signal from the transmitter.  The transmitter radiates a feeble electromagnetic wave of less than 30 kHz corresponding to the sound range.  The fact that the frequency of output from the transmitter is of a low frequency level corresponding to the sound range provides a greater allowance in the receiver for fluctuations in the frequency of signals received and thus good operation stability of the receiver.  False alarming due to extraneous radiation is very unlikely to occur, and other components are free from the possibility of malfunctioning.  In addition, the invention provides for compacturization of the receiver-side component or body unit.

Patent CA-2065471-C (CA)
Title: System for squelching communications circuits terminating in failed ring nodes
Inventor: KREMER WILHELM
IPC: H04J3/14
Filed: 1992-04-07
Granted: 1999-03-16
Abstract: Misconnections between communications circuits in a bidirectional line-switched ring transmission system are eliminated by deterministically squelching in adjacent ring nodes, i.e., loop-back-switching nodes, communications circuits terminated in failed ring nodes in the ring transmission system. The deterministic squelching is realized by provisioning the ring nodes with all active communications circuits including those passing through the node which are terminated in other ring nodes in the bidirectional line-switched ring transmission system. Then, when one or more adjacent ring nodes fail, all active communications circuits terminated in those failed ring nodes are squelched in the adjacent ring nodes, i.e., in the loop-back-switching ring nodes.
Patent CA-2066475-C (CA)
Title: Method and apparatus for continuously hot rolling of ferrous long products
Inventor: SHORE TERENCE M
IPC: B21B1/10
Filed: 1992-04-21
Granted: 1997-06-03
Abstract: A method and apparatus for continuously hot rolling ferrous long products which employs a "post finishing" block of roll stands downstream from the finishing stands of the mill.  Water boxes or other like cooling devices are preferably interposed between the last mill finishing stand and the postfinishing block.  The post finishing block includes at least two reduction stands followed by at least two sizing stands.  The reduction stands have an oval-round pass sequence, and the sizing stands have a round-round pass sequence.  Clutches or other equivalent means are employed in the drive train to permit changes to be made between the interstand drive speed ratios of at least the reduction stands, and also between some or all of the remaining sizing stands.   A fixed rolling schedule is provided for all roll stands in advance of the finishing stands.  Thus, the finishing group is supplied with a first  process  section  having  a  substantially  constant  cross sectional area and configuration.   The first process section is passed through the finishing group and rolling occurs in either none, some, or all of the finishing roll stands, depending on the size of the desired end product.   The product then continues through water cooling boxes to the post finishing block as a second process section.  The interstand drive speed ratios of the roll stands in the post finishing block are appropriately adjusted to accommodate rolling of the second process section.   The total reductions affected in the initial reduction stands of the post finishing block are well above 14%, thereby producing an increased energy level in the product sufficient to create a substantially uniform distribution of fine grains.  Typically, such total initial reductions will be on the order of about 20-50%.   Significantly lighter reductions on the order of 2-15% are taken in the final round-round pass sequences of the post finishing block to obtain the desired close sizing tolerances in the finished product.  The time interval between the higher reductions affected in the oval-round pass sequence and the lighter reductions affected during sizing in the round-round pass sequence is such that the resulting grain size throughout the product cross section will not vary by more than 2, and in most cases by less than 1 ASTM grain size number.

Abstract: A foil which is unrolled from a band coil is coated at uniform intervals with strips of adhesive and cut into strips in the direction of uncoiling.      The strips are then piled on top of one another with their respective adhesive strips parallel but in staggered positions, and are thereafter adhesively bonded together under pressure to form a stack with ends which is finally expanded. The foil band is cut into strips whose width corresponds to the honeycomb core height desired. One strip is passed over a position detector which, by detecting the adhesive strips, determines its position relative to the first end of the stack and activates an electronic control unit to control a positioning drive and a cutting device. The positioning drive positions the strip relative to the stack at one of its ends in such a way that the adhesive strips on the strip lie between those of the underlying strip and the strip is held fast at the one end. Beginning from the one end, the strip is then progressively bonded to the underlying strip, working towards the direction of the other end; shortly before bonding at the other end, the strip is cut by the cutting device to a preselected length limited by the ends, which correspond to the desired width of the honeycomb core to be made; the process then repeats itself. Equipment for carrying out such process and its application for the continuous production of a composite plate with an expanded honeycomb core and at least one covering layer are also disclosed.
