Inventor: SOGO HIROSHI
IPC: H05K3/38
Filed: 1991-11-20
Abstract: PURPOSE:To eliminate pits of a printed circuit board by applying silane-coupling agent to a plating resist layer to be copper-plated so that the resist surface may become hydrophilic to prevent bubbles from attaching. CONSTITUTION:Through holes 3 are opened in a glass-epoxy board 1 having copper foil on each side. After the whole surface is activated, electroless plating 4 is formed. Plating resist is applied in a circuit pattern on the board surface. After degreased and soft-etched, the board is immersed in an aqueous solution of a silane-coupling agent expressed by NH2C2H4NHC3H6Si(OCH3)3 to form a silane-coupling layer on the surface of the board. Copper plating 7 is applied to the board where the resist does not exist. After solder plating 8 is applied to the copper plating, the plating resist is removed, and then excess copper plating is removed using aqueous ammonium chloride.

Title: Multifunctional telephone set
Inventor: ITO MORIHIKO
IPC: H04M1/00
Filed: 1989-11-27
Abstract: PURPOSE:To easily take a countermeasure in malfunction and to improve the maintainability by informing the private branch exchange of a main body of whether the telephone set is initialized by turning on the power source or owing to a program runaway. CONSTITUTION:The circuit consisting of a resistor 1, a capacitor 2, and an inverter 3 sends out a signal when the power source is turned on to set an FF 6 and also inputs the signal to a microcomputer 8 through an OR gate 7 to initialize the microcomputer. Then the computer 8 resets a timer counter 5 periodically through an out port so that the counter does not enter a time-out state. If, however, a program runs away, the counter 5 is not reset periodically, the counter 5 enters the time-out state, and its output is inputted to the computer 8 through the gate 7, so that the computer 8 is reset and initialized. In this case, the computer 8 informs the private branch exchange of the factor which caused initialized, through the FF 6 and a communication control part 9, so a countermeasure for malfunction is easily taken and the maintainability is improved.

Title: Method and device for using walsh shift keying in spread spectrum communication system
Inventor: ZEHAVI EPHRAIM
IPC: H04W84/06
Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To increase pilot energy, to estimate the phase of communication signals and to perform tracking by modulating a digital data symbol relating to M by using at least two orthogonal modulation symbols of a length (n) including one or more Walsh functions. SOLUTION: M is equal to the product of the total number of orthogonal functions used at the time of generating the product of the functions and the modulation symbol used so as to generate respective individual symbols. The product of the function and a coefficient is selected so as to make M smaller than 64. Modulation symbol output for performing transmission is generated corresponding to the binary value of an input data code symbol. At least one, normally two, orthogonal function generator supplies the first and second orthogonal functions of the length (n). A selector or a selection means receives a user data symbol and the first and second functions, outputs the first orthogonal function when the symbol is the value of 1 and the second orthogonal function when it is the value of 2 and responds to the binary value of the data symbol.
