Title: Manufacture of multilayer printed interconnection board
Inventor: OCHIAI RYOICHI
IPC: H05K3/46
Filed: 1987-05-27
Abstract: PURPOSE:To reduce the cost of a multilayer printed interconnection board, and to improve reliability on the conduction of a via hole by coating and protecting the whole surface of a polyimide resin layer with an alkali-resistant resin film and manufacturing the multilayer printed interconnection board having an upper layer conductor pattern by combining an electroless plating means and a lift off method. CONSTITUTION:An alkali-resistant resin film 10 is screen-printed onto the surface of a polyimide resin layer 3 except the internal surfaces of lower holes 5A for via holes thinly, and dried. A ceramic substrate 1 is dipped in a plating tank, and electroless-plated with a conductor metal such as copper, and a conductor film 4A is formed onto the surface of a resist 11, the exposed surfaces of alkali-resistant resin films 10 on which the resist 11 is not applied, and the whole surface of the ceramic substrates 1 in the lower holes 5A for the via holes. The resist 11 is peeled, and upper- layer conductor patterns 4 and the conductor films 4A except the via holes 5 are gotten rid of through a lift-off method in which unnecessary conductor film sections shaped onto the top face of the resist 11 are removed. Accordingly, reliability on the conduction of the via holes acquired is improved.

Title: Automatic answering telephone set
Inventor: CHIBA YOKO
IPC: H04M1/64
Filed: 1987-05-27
Abstract: PURPOSE:To transmit a previously prepared message to a specific calling subscriber even when a called subscriber himself cannot attend the call, by asking the calling subscriber to transmit a key, and when one of stored keys coincides with the inputted key, outputting the message corresponding to the coincident key. CONSTITUTION:Plural keys are stored in a storing means 14 after coding the keys and messages corresponding to the keys are individually stored. At the time of automatic answering, the calling subscriber is asked to transmit a key, and whether one of the keys stored in the means 14 coincides with the inputted key or not is discriminated by means of a discriminating means 17. In accordance with a discriminated result, an output controlling section 12 controls a message outputting section 13 to select and output the message corresponding to the key from the storing means 14. Therefore, even when the called subscriber himself cannot attend the call, the previously prepared message can be transmitted to the calling subscriber.

Title: Method for simplifying outlike data
Inventor: KAWAKITA YASUHIRO
IPC: G06T5/00
Filed: 1995-05-29
Abstract: PURPOSE: To prevent overlap and intersection of plural outlines by removing apex coordinate data related to loacally rugged parts of an outline shape. CONSTITUTION: When the plotting processing of three-dimensional topographic data to a plotting memory 24 is terminated, a CPU 23 sets a section parameter (k), which prescribes a processing object section, to initial value 0. The processing object section (k) is subjected to blind alley detection processing to discriminate whether a blind alley is detected or not. If a blind alley is detected, blind alley removal processing is executed, and the control is returned to the blind alley detection processing. That is, small local recessed parts of the outline shape are detected and apex coordinate data related to these parts is removed from original outline data, thereby converting the original outline data to simplified outline data.  As the result, the rough outline shape of original outline data is faithfully kept even after the simplification processing, and overlap or intersection of outlines are prevented even if there are plural nearby outlines.

Filed: 1979-10-09
Abstract: PURPOSE:To improve the activity of a catalyst at a low temperature, and to simplify a process of manufacture, by a method wherein an oxide of chrome or a chrome alloy is arranged to an intermediate layer between a metallic carrier and catalyst metal. CONSTITUTION:The whole surface of a metallic carrier 21 is laminar, netted, etc. shapes is coated with a heat insulating material 31, an oxide of chrome or a chrome alloy as an intermediate layer, by means of a plating method between the metallic carrier 21 and catalyst metal 32. The catalyst metal 32 is thereafter plated, oxidized and reduced, thus manufacturing a metallic catalyst. With the metallic catalyst produced in this way, a process of manufacture is simple, and activity at a low temperature is improved because the heat insulating material prevents the temperature drop of the catalyst metal even in an atmospheric gas at a low temperature.

IPC: C08J9/34
Filed: 1980-09-18
Abstract: Cellulose acetate containing membranes which have pore diameters of about 10 to 1000  ANGSTROM  are modified by reacting these membranes (a) with (b) an at least difunctional compound, e.g. cyanuric chloride, (c) a polyfunctional oligomer or polymer, e.g. polyethyleneimine, and then with (d) a compound which contains at least one ionic group and one group capable of reaction with component (c). Reactant (d) is necessary only if the polyfunctional component (c) does not already contain sufficient ionic groups. The novel membranes are suitable for ultrafiltration and can be used for example for separating monovalent ions of low ionic weight from polyvalent ions of low or relatively high ionic weight of from monovalent ions of relatively high ionic weight and for separating ionic compounds (salts) from non-ionic (organic) compounds or from ionic compounds which have a different molecular weight or opposite charge. They can be used for example for separating salts from organic compounds (dyes) or in waste-water treatment.

Filed: 1990-05-23
Abstract: PURPOSE:To evade the frequent interruption of the operation of a processor by providing an interruption mask means, and monitoring the number of instruction which are altered every time an interruption signal is accepted and outputting an interruption signal to the processor when the number of instructions reaches a specific number. CONSTITUTION:An process informing means 20 provided to the processor 1 informs a processor 3 of a group of instructions required to complete a process and the number of the instructions in advance. The instruction buffer means 21 of the processor 3 is stored with the group of instructions.
