Patent CA-2113988-A1 (CA)
Inventor: SAKAI HISAO
IPC: F01L13/00
Filed: 1994-01-21
Abstract: An intake system for an internal combustion engine includes first and second intake valve bores provided to face a combustion chamber and to be independently opened and closed by first and second intake valves, and first and second intake ports which are connected to the corresponding intake valve bores with a partition wall interposed therebetween and which communicate with a common intake passage. In a particular operation range of the engine, an imbalance is produced in the concentration of the air-fuel mixture flowing through the first and second intake valve borer into the combustion chamber on the basis of a difference between the amounts of fresh air flowing into the first and second intake ports. The intake system further includes a communication hole provided in the partition wall for putting the first and second intake ports into communication with each other. This provides for improvements in the lean combustibility and in the nature of the exhaust gas.

Inventor: KOU YUKARI
IPC: H04W74/08
Filed: 1994-02-24
Abstract: In a satellite communications system comprising a central station and remote stations, each remote station sends a packet containing user data on a randomly determined slot of a forward satellite channel. If the packet is received by the central station, it sends traffic data and an acknowledgment signal. If the absence of acknowledgment signal is detected by the remote station, it generates a random number in a range determined by the traffic data and increments a count value indicating a number of instances where the acknowledgment signal is not returned. The packet containing the count value is retransmitted on a time slot determined by the random number. If an acknowledgment signal is received, the count value is reset to zero. The central station, on receiving a packet, generates an acknowledgment signal, and derives a sum of the total of packets received during a predetermined interval and the total of count values contained in such packets. The traffic data is derived from the sum and transmitted with the acknowledgment signal and host data on a backward satellite channel.

The antiulcer agent comprises rhamnan (a homopolysaccharide), rhamnose or a rhamnose oligomer as an active ingredient.          Rhamnan is prepared by separating rhamnan sulfate from rhamnan sulfate-containing algae and desulfurating the rhamnan sulfate.  Rhamnan oligomers are prepared by hydrolyzing rhamnan obtained by desulfuration of rhamnan sulfate or by hydrolyzing microbial cells of a Bifidobacterium or polysaccharides separated therefrom.

IPC: H03M13/00
Filed: 1994-05-03
Abstract: Punctured binary convolutional codes are used in a trellis coded modulation scheme to achieve spectral efficiencies as high as those of multi-dimensional codes, using simple hardware.  A base rate 1/2 binary convolutional code is punctured to rate n/k.  The output of the punctured encoder is mapped to a four-way partition of a 2N point two-dimensional QAM constellation.   The four-way partition consists of a two-way partition in both the I and Q dimensions.  The two-way partitions of each dimension are used to transmit the two level output of the rate n/k binary convolutional coder. (N-2) "uncoded" bits are transmitted by selecting the unique constellation point in a partition group. The code has an average throughput of (N-2)+2n/k bits per symbol.  The invention is also applicable to trellis coded amplitude modulation schemes based on 2N possible amplitude levels provided along a one-dimensional constellation.

Title: Electrical connector having an insertion and extraction slide
Inventor: AINCERI RACHID
IPC: H01R13/629
Filed: 1994-05-19
Abstract: ABSTRACT OF THE DISCLOSURE         A  rectangular  electrical  connector  comprises  a receptacle having two side walls that define two parallel passages  extending  in  the  longer  direction  of  the receptacle and a plug displaceable with respect to the receptacle in an insertion direction. A U-shaped slide for forced insertion and extraction of the plug slides along the passages orthogonally to the insertion direction.  It is  formed  with  open-ended  grooves  for  receiving  studs projecting  from the plug orthogonally  to the insertion direction,  having a shape such that displacement of the slide in a first direction causes the studs to move along the grooves from the open ends thereof, and displacement in the opposite direction forces the studs out of the grooves.  The  slide  has  resilient  retaining  lugs  that project outwardly from the slide when at rest. Cut-outs are formed in the side wall of the receptacle to receive the lugs and are of a length enabling to fully insert the slide but preventing full extraction of the slide.  The lugs have a shape such that the force required for pulling the slide out of the receptacle is much greater than the force required for inserting it into the receptacle.

Title: Bulk carrier bag with blockage removal means
Inventor: CHOUINARD PETER
IPC: B65B69/00
Filed: 1994-08-30
Abstract: A bulk carrier bag adapted to be suspended on a dispenser of a material handling system is able to break up flow blockages in powdered material which is dispensed from an aperture in the bottom of the bag.  Such flow blockages occur when packed material in the bag forms a bridge across the top of the aperture.  The subject bridge-breaking means is useful when vibration of the bag or similar techniques have not proven sufficient to restore material flow.  An inflatable air tube is positioned intermediate an outer shell of the bag and an inner liner, preferably to extend around the aperture in the bottom of the bag.  As the tube is inflated, the bottom of the liner distorts to fracture the bridge formed in the material, thereby restoring flow of material through the aperture.
