IPC: C08J9/14
Filed: 1980-04-14
Abstract: 1. A process for the preparation of a resilient foam based on a melamine/formaldehyde condensate by foaming an aqueous solution or dispersion, which contains a melamine/formaldehyde precondensate, an emulsifier, a volatile blowing agent and a curing agent, with or without conventional additives, and then curing the foam, wherein a) the concentration of the precondensate in the mixture of precondensate and water (without additives) is selected to be above the salient point of the 1st derivative of the curve which is obtained when, keeping all other conditions constant, the amount of water in the mixture of precondensate and water is varied and the viscosity of the mixture (measured at the boiling point of the blowing agent under the conditions prevailing at the start of foaming) is plotted against the concentration of the precondensate, which concentration must however not be higher than the value which in the curve described corresponds to a viscosity of 5,000 dPas, b) during the foaming process, up to the time at which the foam has reached 80% of the maximum attainable rise height, the viscosity of the aqueous solution or dispersion must not fall below the value which, in the curve described under a, corresponds to the minimum concentration defined there, but must not exceed 6,000 dPas, and c) after reaching the time defined under b, the viscosity exceeds a value of 10,000 dPas, due to curing of the precondensate, within 8 min, the viscosities referred to in b and c being measured, in each case, on a parallel system which is free from blowing agent.

Title: Method and circuit for testing semiconductor integrated circuit
Inventor: INAGAKI KOJI
IPC: G01R31/28
Filed: 1992-03-05
Abstract: PURPOSE:To improve the fault detection rate without adding any pattern nor special testing function by adding a pattern detection circuit to a fault- undetected part and outputting a total pattern from one or more output pins for testing. CONSTITUTION:The figures show results of normal logical simulations in which the fault of a circuit added with a test circuit is not assumed and the (a) in the figures show a strobe point which is compared with an expected value for detecting a fault at the time of executing a fault simulation. When zero-fixed fault is defined against the terminal of a logic element (A), noncoincidence with the expected value is detected at strobe points (c) and (c') and a fault is detected as a result of the simulation. Thus the output of the terminal of one element selected output of logic elements (A) to (C) changes from that before assumption at the strobe point of a test pattern due to the assumed zero- or one-fixed fault. In this case, since the output of exclusive OR is necessarily outputted in an inverted state against the output value obtained before assuming fault, the fault is detected.

Title: Private branch exchange system
Inventor: NAKAMURA MASAYASU
IPC: H04Q3/58
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a camp-on function in a system where respective terminals share a speech channel of a private branch exchange(PBX). SOLUTION: When, for example, a camp-on of a key telephone set 10-1 is registered and a terminal to be registered is an ISDN terminal 14-1 in this PBX system, a camp-on control part 18c refers to the availability of the speech channel of a channel managing part 18a and to the conditions of a registering terminal and a terminal to be registered at a terminal managing part 18b. Thus, even when the registering terminal and the terminal to be registered are not used, a camp-on processing is not performed unless the B channel is idle. Only when at least one B channel is idle and the registering terminal and the terminal to be registered are not used, on the other hand, the camp-on processing is performed.

Title: Selecting method for candidate item of recognizing device
Inventor: NAKAMURA MASAHIRO
IPC: G06K9/68
Filed: 1986-03-07
Abstract: PURPOSE:To obtain a high recognition rate by selecting a candidate which has the largest number of items as a candidate item when >=2 candidates appear at equal distance. CONSTITUTION:A feature quantity extracted from an input pattern and feature quantities in a dictionary are distance-processed to decide whether or not the extracted feature quantity is determined as one in a candidate group by a certain threshold level. The number of the same items is counted when it is registered in the candidate group. Then, if a candidate which has distance equal to the shortest distance of the candidate group selected by said processing appears, the distance and candidate are stored. When the candidate is the same item with the shortest-distance candidate, they are not stored although the distance is equal. Thus, all distance values of the candidate group are checked and the candidate with the shortest distance is selected as the final candidate. Then, when there are plural items with equal distance, the number of the same items in the candidate group is checked and one candidate which has the largest number is selected as the final candidate.

IPC: B23K26/34
Filed: 1984-03-13
Abstract: PURPOSE:To enable improvement in the quality of an alloy layer formed on the surface of a base metal by weaving prescribed metallic wires into a net shape to form a material to be melted, disposing such material on the surface of the base metal and melting the material to be melted and the base metal by beam-like heat energy.

Title: Method for extending service life of metallic frame for centrifugal casting
Inventor: KUROTOBI MANABU
IPC: B22D13/12
Filed: 1993-03-11
Abstract: PURPOSE:To reduce heat fatigue and to extend the service life of a metallic frame by forming plural peening marks on the inner surface of the metallic frame and thereafter, applying shot peening on the inner surface of the metallic frame. CONSTITUTION:In order to prevent the slipping of molten metal in the inner surface of the metallic frame 1 for centrifugal casting, plural half-spherical peening marks 2 are formed by peening. Thereafter, to the inner surface of the metallic frame 1 for centrifugal casting applying the peening, the shot peening is applied with steel shots 3. As the result of the shotpeening, the inner surface of the metallic frame 1 is plastic-deformed to develop compressive residual stress. For example, plural spherical steel sheets 3 having 0.8mn diameter and 550 Hv hardness are collided to the inner surface of the metallic frame 1 at 60m/s speed. By this method, as the fatigue strength is improved because the compressive residual stress opposes against the tension heat stress acted on the inner surface of the metallic frame, the development of crack is restrained.

Title: Solid state image pickup plate
Inventor: KAWAGUCHI TOSHIHIKO
IPC: H04N5/335
Filed: 1982-03-27
Abstract: PURPOSE:To supress greatly an interaction between the picture elements adjacent to each other and especially the blooming, by forming the 2nd semiconductor substrate of an island form which includes a photodetecting part and a signal reading part forming a picture element on the 1st semiconductor substrate. CONSTITUTION:A P type semiconductor substrate 9 is formed on an N type semiconductor substrate 8. The substrate 9 includes an N type layer 2 forming a photodetecting part and an N type layer 3 forming a signal reading part which form a picture element together with a gate electrode 4. Separating layers 12 and 12' formed with N type semiconductors are set between the substrate 9 and P type semiconductor substrates 9' and 9'' of two picture elements which are adjacent to each other. Therefore, the wells of substrates 9, 9' and 9'' are formed into island forms respectively. In other words, the picture elements are formed independently of each other in the island-shaped P type semiconductor substrates shown by the substrates 9, 9' and 9'' respectively. Thus a carrier 6 going downward is absorbed by the substrate 8; while a carrier 14 going toward the substrate 9' is absorbed by the layer 12'. As a result, it is pissible to suppress greatly an interaction between the adjacent picture elements and especially the blooming.
