Title: Surface treatment of metal
Inventor: FERRIER DONALD
IPC: C09J5/00
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To increase the adhesive strength between a metal and a polymeric material by bringing the metal surface into contact with an adhesion promoting composition consisting of an oxidizing agent, an acid and a corrosion inhibitor, further a halide ion source, if necessary, and a water-soluble polymer, as required, and then with an alkaline soln. SOLUTION: The surface of copper is suitably treated with an acidic peroxide adhesion promoting composition and then with alkaline treatment. A minute coarse chemical conversion applied surface is formed on the metal by the composition, the adhesiveness of the formed surface is remarkably increased as compared with an untreated metal surface, and hence the surface is appropriately combined with a polymeric material. Further, the increased adhesion is kept on the applied surface over a long period, and the possibility that an undesirable reaction takes place between the metal and material is reduced over a long period. By such a treatment, the intermediate layer is combined with a prepreg or a picture formable dielectric, for example, to form a multilayer printed circuit board.

Title: Solar heat collecting device
Inventor: SUGA KUNIHIRO
IPC: F24S90/00
Filed: 1981-12-02
Abstract: PURPOSE:To facilitate the application of the device by a method wherein a plurality of heat exchangers are connected in series in a heat collecting circuit and a heat medium flow passage to bypass a solar heat collecting part is provided. CONSTITUTION:At a time of heat collection, a heat transfer three-way valve 15 forms a heat collecting circuit 6 in which a heat medium flows through a heat collector 1, and each pump accumulates the solar heat by the operation of the heat exchangers in a heat accumulating tank 8 for room heating or a hot water tank 12 for hot water supply. On the other hand, when the heat collector 1 is not collecting heat, the heat transfer three-way valve 15 forms a heat transfer circuit in which the heat medium bypasses the heat collector 1. In this instance, if a room heating load is zero and a difference is found between the heat accumulating tank 8 and hot water tank 12, the heat collecting pump 3, heat exchanger pump 7 for room heating and heat exchanger pump 11 for hot water supply are driven to transfer the heat through the heat exchanger 4 for room heating and heat exchanger 5 for hot water supply. As the heat transfer between the heat loads is very easy, a simplification of the equipment and a reduction of installation space can be realized.

Title: Semiconductor device for automatic balance circuit
Inventor: ISU KENJI
IPC: H04S3/02
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To make an external attaching parts unnecessary, to suppress an influence by an external noise and to suppress an augmentation of mounting space by amplifying a signal of the first channel, amplifying the signal in accordance with reverse characteristics, detecting a condition of balance of both signals, controlling an interest of an amplification circuit and making a circuit of a construction for moving to a balanced condition integrally an integrated circuit. SOLUTION: In an automatic balance operation, a clock selection circuit 12 selects a reference signal CLK1 by a control signal of an automatic balance ON/OFF changeover circuit 4 and supplies the CLK1 to an UP/DOWN counter. When an Lch OUT is bigger than a Rch OUT, a voltage signal of a + polarity is outputted by an L/R balance detection circuit 3 and a counter 11 executes a counting up by the CLK1. Every time a count value becomes large for 1, a gain of a VCA: 1 is lowered for 1dβ and the gain of the VCA: 2 is raised for 1dβ. At the time when a difference of OUT between the Lch and the Rch becomes O and is balanced, a counting operation is stopped. Accompanying to an integration, the number of pin can also be reduced.

IPC: H04N1/40
Filed: 1993-07-07
Abstract: PURPOSE:To keep the gradability of photograph even under the state that photograph, character and figure are mixedly present, and contrive to clarify the outline part of the character and the figure by a method wherein picture signal is formed by synthesizing signals, which are obtained by respectively converting noticed picture elements into pulse signals having the predetermined width with a first and a second converting means when the picture element is recognized as binary-coded picture element or halftone picture element with a discriminating means. CONSTITUTION:When a picture element under notice is recognized as binary-coded picture element at a picture element discriminating circuit 4, the picture element under notice is converted into pulse signal at a binary coding circuit 5. When the picture element under notice constitutes an outline part, whether edge part or not is judged. When the picture element under notice is a part excluding the edge part of the outline part, the width of pulse is controlled so as to make its outline smooth. On the other hand, when the picture element under notice is recognized as halftone picture element, the picture element under notice is converted into pulse signal at a halftone processing circuit. Normally, the number of gradations representable with an electrophotographic printer is fewer than the number of gradations of input data. Therefore, in the electrophotographic printer, some picture element are controlled into cell so as to represent the gradation of the whole by combining the representation of the gradations of respective picture elements in the cell.
