Title: Manufacture of printed wiring board
Inventor: MANIWA AKIRA
IPC: H05K3/40
Filed: 1991-03-11
Abstract: PURPOSE:To reduce the occurrence of defects such as unconnection due to shortage of solder by forming a recessed part to trap solder in on a surface- mounted pad by copper etching. CONSTITUTION:A hole 2 is made in a copper clad laminate and then an electroless copper plated layer 3 is applied to form a through-hole. After that, lamination, exposure and development are conducted using a dry film to form the first etching mask 4 on the surface. Nextly, the first copper etching is conducted using a cupric chloride solution to form a recessed part 5 on the surface of a copper foil 1. Then, lamination, exposure and development are conducted using a dry film to form the second etching mask 6. Nextly, the second copper etching is conducted using a cupric chloride solution to pattern the copper foil 1. Then, a photo SR mask 7 is formed in a copper foil-eliminated area using photo SR. After that, solder is trapped in the recessed part 5 which is formed by copper etching and a solder coat 8 is applied. By this method, enough quantity of solder is ensured at the time of mounting and thereby a defective connection-free printed wiring board can be obtained.

Title: Bimorph actuator
Inventor: KAWAI TAKASHI
IPC: H01L41/09
Filed: 1989-02-23
Abstract: PURPOSE:To improve an actuator in reliability dispensing with an adhesive agent by a method wherein piezoelectric materials different from each other in Curie point are used, and they are made opposite to each other in polarization direction as they are molded in an integral structure. CONSTITUTION:Two types of piezoelectric materials are used. A first piezoelectric material is large in electric field resistance, hard, and high in Curie point. A second piezoelectric material is small in electric field resistance, soft, and low in Curie point. These piezoelectric materials can be obtained by controlling, for instance, Pb(Co1/3Nb2/3)O3-PbTiO3-PbZrO3 ceramic in composition ratio. The first piezoelectric material is heated at a temperature of 400 deg.C and a voltage of 1000V is applied to electrodes. Then, after the voltage is made to drop to 500V, the voltage inverted in polarity is applied for 10 minutes or so and the material is made to drop to a normal temperature. By heating and applying voltage, the first and the second material can be formed opposite to each other in polarization direction making their joined face as a boundary without an adhesive agent.

Title: Scanning stop protecting circuit for display device
Inventor: SONOBE SATOSHI
IPC: G09G3/30
Filed: 1990-02-26
Abstract: PURPOSE:To cope with the scanning period of the display device and to incorporate in a gate array, etc., by turning off all outputs of a scanning-side driver according to the output of a counter whose counted value is reset with a scanning signal outputted in each scanning period when the scanning-side driver operates normally. CONSTITUTION:When the scanning of the scanning-side driver 4 is performed normally, the counter 10 is reset with the scanning signal 50 before the counted value of the counter 10 reaches a specific value, so the output of the counter 10 is held at a constant level. When the scanning of the scanning-side driver 4 is stopped owing to some fault, the counter 10 is not reset and its counted value exceeds the specific value, so the output state of the counter 10 changes. Therefore, if the output state of the counter 10 changes, all the outputs of the scanning-side driver 4 are turned off to protect the display device in the stop state. Consequently, coping with the scanning period of the display device and the incorporation in the gate array, etc., are made possible.

Title: Processor for signal
Inventor: BURAIAN DEIBUITSUDO ATSUKURAND
IPC: G10L15/32
Filed: 1982-03-20
Abstract: Known signal processors for matching signal patterns commonly compare an unknown signal with one of a set of reference signals. Various comparison techniques are known. One comparison technique for solving a parenthesization problem includes an orthogonal array of interconnected cells which are adapted for dynamic programming and for extending data and control information in a generally left-to-right direction as well as in a bottom-to-top direction. For solving a pattern matching problem, known arrangements for extending control information in a generally left-to-right or bottom-to-top direction do not appear to be satisfactory. The disclosed signal processor for matching signal patterns and for dynamically time warping an unknown input signal with a reference input signal generates a measure of the correspondence between the input signals. In generating the correspondence measure, the processor includes an arrangement for controlling all processor cells on a predetermined diagonal of the array of cells. Thereby all cells coupled to the diagonal can operate in parallel to increase and improve the efficiency of the signal processor. The processor also includes an arrangement for controlling all processor cells on each diagonal of the array of cells. As a result, not only can all cells on each diagonal operate in parallel but also each of the plurality of diagonals can operate in parallel for processing the same or different sets of input signals. Thereby, a still further increase in the efficiency of the signal processor obtains.
