Title: Surface-treating method for ink jet recording head
Inventor: SATO MOTOAKI
IPC: B41J2/135
Filed: 1995-03-15
Abstract: PURPOSE: To form a liquid-repellent layer which has excellent liquid repellency, wear resistance and adhesive properties with a base material by plating such as composite eutectoid plating in which fluorine polymer is dispersed in a method for surface-treating an ink jet recording head in which the ink discharge port peripheral edge and its outer periphery of the head are plated. CONSTITUTION: A method for surface-treating an ink jet recording head comprises the steps of dispersing fluorine polymer in a metal matrix, forming a liquid-repellent layer 20 at least at an orifice 14 surface of the head and the predetermined width from the edge of the orifice 14 on the surface for surrounding the orifice 14 by composite eutectoid plating, and chamfering the end face of the orifice surface. Thus, excellent liquid repellency is exhibited by fluorine polymer fine particles precipitated on the surface. Since the matrix is metal, it is scarcely damaged to obtain high adhesive properties. Since the end faces of the orifice is chamfered and the surface for surrounding the orifice 14 is placed, strong wear resistance is obtained.

Title: Manufacture of printed board
Inventor: KASAI OSAMU
IPC: H05K3/38
Filed: 1989-03-07
Abstract: PURPOSE:To increase a bonding property between a glass fiber and resin and hence reduce generation probability of any crack by subjecting the surface of the close-like glass fiber used as a core material of the surface board to a rough surface treatment. CONSTITUTION:A rough surface treatment is applied onto the surface of a close-like woven glass fiber 11 to form the unevenness thereon. Thereafter, it is impregnated with resin 12 such as epoxy, etc., to form a prepreg 1. The rough surface treatment can be performed by dissolving the surface of the glass fiber with an about 5% concentration hydrogen fluoride(HF) solution. By previously roughening the surface of the glass fiber 11 as such, the bonding property of the fiber to the resin is improved, and hence peeling strength between the prepreg 1 and the glass fiber of the substrate yielded by heating and hardening the prepreg 1, and the resin is increased.

Title: Multiplying circuit for element belonging to galois field gf (2m)
Inventor: SATO TSUTOMU
IPC: G06F7/52
Filed: 1987-03-10
Abstract: PURPOSE:To perform the arithmetic processing at a high speed by using a shift register connected to a primitive irreducible polynomial for a Galois field of GF (2<m>), a microprocessor and its subordinate RAM, etc., to constitute a multiplying device. CONSTITUTION:For a shift register 1 connected to a primitive irreducible polynomial of GF (2<4>), the lowest order is regarded as X<0>=1 and then as X<1>, X<2> and X<3> toward the higher orders. Then the register 1 is sent toward the highest order from the lowest one when a clock CLK is applied via a lead wire 4. When X<4> is obtained with transmission of X<3>, the X<4> is written to X<0>=1. At the same time, the value with which the X<0>=1 is sent and the output received from the X<4> are calculated by an exclusive OR circuit 11 and the result of this calculation is written to the X<1>. A microcomputer 2 contains a CPU, a RAM and a ROM together with a multiplicand register area 21, a multiplier register area 22 and a result register area 23. Thus the register 1 connected to the primitive irreducible polynomial is actuated for fast production of a desired polynomial.
