Patent JP-H03296295-A (JP)
Title: Manufacture of multilayer printed circuit board
Inventor: HATAKEYAMA SHUICHI
IPC: H05K3/46
Filed: 1990-04-13
Abstract: PURPOSE:To prevent and suppress generation of negative etchback by covering a conductor circuit in a through hole or a nonthrough hole with etching resist when metal copper and copper oxide or only metal copper is melted to be removed from an insulation organic board. CONSTITUTION:Copper foils are formed as outermost layers, and so laminated together with an inner layer circuit that the forming surface of a copper oxide 1 is brought into contact with a base material 2 of insulating organic material. A through hole or nonthrough hole is formed, and smeared as required. An inner layer conductor 3 in the through or nonthrough hole is covered with insoluble or hard soluble substance to copper etchant. The surface of a board is polished to expose the foil. Metal copper and copper oxide or only the metal copper is removed from the organic base material. As required, the conductor covering substance in the through or nonthrough hole is removed, and wired including electroless plating to form a wiring.

Title: Semiconductor protector
Inventor: TAKIGAMI KATSUHIKO
IPC: H01L29/74
Filed: 1984-05-18
Abstract: PURPOSE:To prevent the destruction of a conduction modulation type element by supplying a gate signal which turns off a gate turn-off thyristor GTO and turning off the gate signal of said element within the storing time of the gate signal. CONSTITUTION:A gage signal e1 of a GTO3 is supplied at a time point t1. While a gate signal e2 of a conduction modulation type element 4 is supplied simultaneously with or a little later than the GTO3. Thus the GTO3 and the element 4 are put under conduction states and a current I flows. When the flowing current is turned off, an OFF gate signal of the GTO3 is supplied at a time point t2. Then the signal e2 is turned off at a time point t2 within a storing time during which the current is flowing. As a result, the anode-cathode voltage v1 of the GTO3 and the source-drain voltage v2 of the element 4 are recovered at a time point near t3.

Title: Material for stamping
Inventor: NOUGUU ATSUO
IPC: H01L23/50
Filed: 1990-04-13
Abstract: PURPOSE:To offer a material for stamping with which a highly reliable device easy in manufacturing can be gotten by plating both sides of a conductive substrate material with palladium or alloy layers having palladium(Pd) for their main ingredients. CONSTITUTION:This material for stamping is one where both sides of iron-nickel alloy 10 called A-42 (alloy 42) 0.15mm in thickness are plated with Pd layers 12a and 12b about 0.5mum in thickness. For a lead frame where material for stamping is used, a uniform plating layer is formed in the inner lead, and a favorable plating area without leakage of plating to the side is formed. Moreover, since there is no necessity to do plating after stamping, the deformation of the top of the inner lead does not occur during carriage to the plating device, and a highly reliable lead frame can be gotten. Furthermore, the cost reduction by the shortening of processes becomes possible.

Title: Method for coiling continuously cast slab by twin drum type continuous casting machine
Inventor: UEJIMA YOSHIYUKI
IPC: B22D11/124
Filed: 1995-04-24
Abstract: PURPOSE: To manufacture a thin slab whose scale is difficult to peel in a cold rolling by descaling the thin slab of a cold carbon steel to be coiled around a coil. CONSTITUTION: A bending type descaler is arranged on an inlet side of a coiling reel, a cooling air nozzle is provided between a casting drum and a bending descaler, cooling air is blown to cool the thin slab of carbon steel at temperature of 400-700 deg.C, the descaling is achieved by the bending descaler, and the descaled thin slab is coiled around a coil. When the temperature of the thin slab exceeds 700 deg.C, the thin slab is immediately and forcibly cooled at 400-700 deg.C, and coil around the coil. When the slab is coiled within this temperature range, the adhesivity of the scale generated after the descaling is excellent, and no abrasion flaw is generated in the coiling. The thin slab difficult for the scale to peel can be manufactured, and the deterioration of the working environment due to the scattering of scales can be prevented in the forming.

Title: Light source device for exposure
Inventor: TOMONO TSUTOMU
IPC: H01J9/227
Filed: 1992-04-20
Abstract: PURPOSE:To enhance the brightness of a light source part and enable a normal black matrix to be formed by deflecting the axis of a discharge lamp by a specific spacing in the opposite direction to an object to be exposed relative to the axis of a cylindrical transparent body. CONSTITUTION:A mercury lamp 4 is arranged in the axial direction of a two-layer structured cylindrical transparent body 2, and its position is deflected by half of the radius R in the opposite direction relative to a panel from the center of the cylindrical transparent body 2. When the light of the mercury lamp 4 is radiated, for example, at the angle of 35 degrees relative to its perpendicular direction, it is refracted at the boundary between the cylindrical transparent body 2 and surrounding air, resulting in advance through the surrounding air at the angle of 29:1 degrees. If the mercury lamp 4 is arranged at the center of the cylindrical transparent body 2, light goes straight without refraction. Thus, the deflection of the mercury lamp 4 results in the compression of the divergence angle of a light flux, so that the density of the light is amplified. When the ratio of the deflection quantity of the cylindrical transparent body 2 relative to the radius R is designed to range from 0.2 to 0.8, its light flux density increases from 1.07 times to 1.4 times. Accordingly, brightness of the light source part can be sufficiently enhanced so as to provide a normal black matrix.

Abstract: PURPOSE:To improve safety characteristics when an electrical cooking device is used and to make a small-sized power supply for a control circuit by a method wherein a driving signal for an informing sound generating member is outputted from a control member during a silent signal period and a sound is generated by a sound generating member subsequent to a time when the operation of a sound amplifying circuit is stabilized.

Since an unstable operation is carried out from a time (a) to a time (b), a silent state is instructed and at the same time this is controlled by a control member 1 in such a way as a sound informing signal is generated subsequent to the time (b) in which the operation of the sound amplifying circuit 8 is stabilized so as to generate sound through a sound generating member 10. In turn, in concurrent with the time in which a signal output from a control output port 4 is transmitted, a driving signal of an informing sound generating member 2 is also outputted from a buzzer output port 3 and a buzzer sound of 'pi-pi' is produced during a time from a time (a) to a time (b) in which an operation of the sound amplifying circuit 8 is unstable, and then a silent signal period of the sound generating member 10 is accommodated.

Abstract: Improved oral dosage formulations for acid-labile dideoxy purine nucleoside derivatives such as ddA, ddI, and ddG, have been developed by incorporating selected water-insoluble buffering systems in the formulation. These novel formulations provide reduced mass dosage units in the form of convenient, palatable chewable/ dispersible tablets or a dry powder sachet. The reduced mass requirement, necessary to allow tablets of reasonable size, was achieved in part by an unexpected 20 to 25% increase in drug bioavailability resulting from use of the selected buffering systems comprised of an insoluble magnesium antacid agent and either dihydroxyaluminum sodium carbonate or calcium carbonate.
