Title: Production of multilayer printed wiring board
Inventor: TAKIZAWA HIDEO
IPC: B29C70/06
Filed: 1990-06-15
Abstract: PURPOSE:To reduce the generation of voids in an inner circuit board by superposing outside and inside prepregs wherein the curing speed of the resin constituting the outside prepreg is slower than that of the resin constituting the inside prepreg on the inner circuit board. CONSTITUTION:For example, a plurality of prepregs each prepared by impregnating a base material such as glass cloth with thermosetting resin varnish such as epoxy resin varnish and drying the impregnated one are superposed on an inner circuit board. In a plurality of these prepregs 3a, 3b, the curing speed of the resin of the prepreg 3a outside with respect to the inner circuit board is slower than that of the resin constituting the inside prepreg 3b. As a result, the outside prepreg 3a starts curing late as compared with the inside prepreg 3b being in contact with the inner circuit board 2. Therefore, the side surface part of the inner circuit board is filled with resin by the cushioning action of the outside prepreg 3a and the generation of voids in this part can be prevented.

Title: Type character recognizing device
Inventor: YAMAUCHI TOSHIFUMI
IPC: G06K9/03
Filed: 1986-07-04
Abstract: PURPOSE:To improve recognition capacity by utilizing relative position relations for a character pattern which is difficult to discriminate only with shape features because of distortion of printing or the like. CONSTITUTION:An input character pattern 11 is converted to binary data by an optical processing part 12, and a character frame having a prescribed size is cut out by a character cutting-out part 14 of a preprocessing part 13. The distance from each side of the character frame is obtained by a peripheral distance part 15, and relative position relations where the centroid of the character is set to three stages, namely, the upper part, the middle part, and the lower part are obtained by a relative position control signal generator 16. A pattern matching part 18 shifts the character pattern in an input character shift part 20 based on the distance from dictionary data and the relative position control signal from the generating part 16, and the pattern is decided again. Thus, the character pattern is decided by relative position relations even if distortion of printing makes character forms of a period and an apostrophe or the like approximately equal to each other.

Title: Generator for electromotive force
Inventor: UEMATSU HIDEO
IPC: H01L35/30
Filed: 1979-12-05
Abstract: PURPOSE:To increase temperature difference with the warm contact side and obtain high electromotive force by forcedly cooling the cold contact side of a thermocouple. CONSTITUTION:When turning a working thumb of an instantaneous water heater, a burner body 2 is ignited while water is passed through a copper pipe 4 at the feed- water side. Consequently, a warm contact section 5a of a thermocouple 5 is heated by the burning flames 3 of the burner body 2 while a cold contact section 5b is cooled at all times by city water passing through the copper pipe 4 at the feed-water side. Thus, temperature difference between the warm contact section and the cold contact section can be increased. High electromotive force is obtained because the electromotive force generator is formed so as to forcedly cool the cold contact side of the thermocouple with water. Thus, power can be supplied more stably when every kind of actuators functioning at low power is started and display elements such as an LED, a liquid crystal are lit.
