Patent JP-H06164119-A (JP)
Title: Printed wiring board
Inventor: TAKAHASHI KIICHI
IPC: H05K3/40
Filed: 1992-11-25
Abstract: PURPOSE:To prevent the deviation of solder from a soldering land in a direction opposite to the advancing direction during flow soldering. CONSTITUTION:An insulation resist 22 is formed on one surface of a board 11 on which a conductive pattern 20 has been formed. This insulation resist 22 is formed on the portion except soldering land 23, and also the insulation resist 22 is formed as a separated land 24 in a ring shape next to the edge of the soldering land 23 with a constant distance from said edge. When a printed wiring board 10 flows over the interface of a solder tank, the surface tension of solder is reduced by the insulation resist 22 at the separated land 24, so that the relative velocity of solder decreases at the inner soldering land 26. Because of this, the deviation of solder in the soldering land in the opposite direction of solder advancement can be prevented during flow soldering operation.

Title: Pulse detection circuit
Inventor: SHIMADA JIRO
IPC: H03K5/02
Filed: 1988-12-13
Abstract: PURPOSE:To eliminate a noise even if the amplitude of an input signal is increased by decreasing or increasing an amplification factor depending whether an output signal level of a variable amplifier circuit is lower or higher than a lower limit reference level and transmitting the result to a noise removing circuit. CONSTITUTION:The variable amplifier circuit 1 decreases the amplification when an upper limit comparison signal VUC reaches a 1st level and increases the amplification factor when a lower limit comparison signal VLC reaches a 2nd level to output an input signal V1 as an amplified signal VA. When the signal VA exceeds the holding signal level of a prescribed level characteristic, the noise removing circuit 2 transmits the result to the output terminal and when lower, the circuit 2 stops the transmission to remove noise. An upper limit comparator 4 compares the signal VA with the upper limit reference level and when the signal VA is higher than the upper limit reference level, the signal VUC is outputted. Moreover, a lower limit comparator 5 compares the signal VA with the lower limit reference level and when lower than the lower limit reference level, the circuit 5 outputs the signal VLC. As a result, the peak clamping characteristic acts on the noise at all times, the noise is removed, only the real signal component can be detected.

Abstract: PURPOSE:To allow the easy flow of liquid on the outer side of tubes and to obtain excellent heat exchange efficiency by bundling many set of triple braided tubes formed by alternately combining three pieces of the tubes consisting of synthetic resins and disposing the bundle along the longitudinal direction of a housing. CONSTITUTION:The triple braided tube sets 21 each set formed by alternately combining three pieces of the tubes 20 consisting of, for example, polycarbonate are bundled and are disposed in the housing of the heat exchanger, by which spaces are formed among the respective tubes 20. The heat exchange water is admitted from an inlet 5 and is discharged from an outlet 6. Meanwhile, blood is admitted from a blood inlet 7 and is discharged from an outlet 8. The heat exchange is then executed through the tube walls of the respective tubes 20 and the blood is cooled or heated. Since the heat exchange water intrudes into the spaces among the respective tubes 20 in this case, the flow resistance of the liquid flowing on the outer side of the respective tubes 20 lowers and the liquid flows extremely easily and uniformly. The contact state between the outer peripheral surfaces of the respective tubes 20 and the heat exchange water is, therefore, improved and the heat exchange efficiency of the heat exchanger is enhanced.

Title: Network repeater and next network transfer destination retrieval method
Inventor: SUKAI KAZUO
IPC: H04L12/66
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To eliminate a time for retrieval processing by a host number bit of a sub-network address by extending a node by the host number bit of the sub-network address at the time of retrieval of a host bit correspondence part of the sub-network address. SOLUTION: When nodes N0002, N0102, N1002 and N1102 of mask length 2 bit are extended at a fixed position of a memory, an address where the mask length 2 bit nodes are extended from values of a 0 and first bits are obtained, any of the mask length 2 bit nodes is jumped to, and a time is reduced by a time for node retrieval done twice. Generally speaking, when a node of a mask length (m) bit is extended at a fixed position on the memory and jumped to at a time, it is possible to reduce the time for retrieval by a time spent for crossing a node for (m) times of the node in total from a mask length 0 bit. On the other hand, as memory efficiency deterioration is invited by extending the node of the mask length (m) bit of the m-powered of 2 number regardless whether or not there is the node, a value (m) is decided from a trade-off between the memory efficiency and performance.
