Inventor: TAKANEZAWA SHIN
IPC: H05K3/46
Filed: 1994-11-10
Abstract: PURPOSE: To obtain the multilayer wiring board having high bonding power onto a plating copper and yet excellent surface smoothness by a method wherein, as for the insulating layer to be multilayered by circuit formation and interlayer connection of viaholes, a sensitive resin containing crosslinked acrylonitrile butadiene rubber particles or a sensitive and thermosetting resin is to be applied. CONSTITUTION: The first circuit 2 is formed on a copper clad glass epoxy resin laminated layer substrate 1. Next, an insulating layer 3 of a sensitive insulating resin containing crosslinked carbonic acid denatured acrylonitrile butadiene rubber particles is formed on one surface of said substrate 1. Next, the whole surface is irradiated with ultravoilet rays through the intermediary of a mask and then not yet exposed paste is selectively removed to form a viahole 6. Next, the insulating layer is immersed in a roughening solution to form roughened rugged shape furthermore, a conductor layer is formed by electrolytic plating step using copper sulfate. Next, a plating conductor is etched away to form the second circuit 8 including the viahole 6 connected to the first circuit 2.  Furthermore, the second circuit 8 conductor surface is made rugged for multilayer lamination to repeat the lamination step.

Abstract: PURPOSE:To make an uncharge or a shortage of paper in a specified paper feed cassette warnable before starting a reserved copy, by installing a device which issues a warning at a time when detecting a fact that whether the specified cassette is charged or not and the paper shortage in the cassette. CONSTITUTION:After reservation setting, a fact that a reserved paper feed cassette is charged or not and a residual quantity of paper in the reserved paper feed cassette is detected by a process n11. At this time, the quotient of (paper discharge maximum housing sheet number D1)/(input original sheet number D2) is set down to D4 while the number of sheets of paper being set in the paper feed cassette is to Cj, respectively. Next, the paper sheet number Cj of each paper feed cassette detected by a paper residual quantity detecting device is divided by the input original sheet number D2, and the values Cj/D2 are compared with the quotient D4. When D4 is larger than Cj/D2, it is the case that whether the specified paper feed cassette is charged not or the case whether the paper runs short or not are judged with a process n16, and when uncharging is the case, an alarm is emitted by a process n17. In addition, when a shortage of paper is the case, the alarm is emitted and simultaneously a display of paper replenishment takes place with a process n18.

Title: Semiconductor circuit device
Inventor: YAMASHITA MASAYUKI
IPC: H03K3/356
Filed: 1988-10-31
Abstract: PURPOSE:To eliminate unstability in latch information and waste current consumption at the time of applying a power source by setting the threshold voltage of a first P-channel MOS transistor differently from that of a second P-channel MOS transistor. CONSTITUTION:Relation between the threshold voltage Vthp1 of the first P- channel MOS transistor 3 and the threshold voltage Vthp2 of the second P- channel MOS transistor 5 is set as ¦Vthp1¦>¦Vthp2¦. Thereby, when a high potential point 1 is increased and exceeds the voltage ¦Vthp2¦, a TR 5 is energized, and the potential of a node 8 rises to a level equivalent to the high potential point 1. At this time, a TR 3 is de-energized, and a node 7 remains at an L level. Furthermore, when the high potential point 1 is increased and exceeds the voltage ¦Vthp1¦, the node 8 increases following that increment, however, the TR 3 remains at a de-energized state since gate potential rises. Therefore, by changing the threshold voltages of the TRs 3 and 5 comprising a latch circuit, it is possible to eliminate the unstability in the latch information and the waste current consumption at the time of applying the power source.

Title: Disk reproducing device
Inventor: NAKANE HIROSHI
IPC: G11B21/08
Filed: 1984-12-27
Abstract: PURPOSE:To prevent a pickup element from going beyond a tracking range during fast searching operation by stopping the generation of a tracking jump signal when the driving voltage of a tracking actuator exceeds a specific value. CONSTITUTION:The driving voltage VT of the tracking actuator (TA)14 is inputted to a level comparator 23 through an LPF22 to detect whether the VT is within a voltage range corresponding to the tracking range of the pickup element or not. A system controller 21 when obtaining the detection output indicating that the VT of the AT14 is within the voltage range corresponding to the tracking range allows a track jump signal generating circuit 11 to generate a tracking jump signal SJ as it is; when the detection signal indicating the VT deviates from the voltage range is obtained, the generation of the signal SJ is inhibited, thereby preventing the pickup element from deviating from the tracking range during fast searching operation.
