Title: Receiver for multifrequency signal
Inventor: FUJII KENSAKU
IPC: H04Q1/457
Filed: 1980-12-04
Abstract: PURPOSE:To make a receiver for multifrequency signals small-size, by causing an output, which is obtained by multiplying an input signal by a window function, to pass through a primary cyclic digital filter to obtain outputs of a real part and an imaginary part and by obtaining an output proportional to the amplitude of a required angular frequency. CONSTITUTION:An input signal from a terminal 1 is multiplied by the square window function, which is supplied from a window function generator 70, in a multiplier 30, and the output is inputted to an adder 43. A filter coefficient ejomegaT (omega is a required detection angular frequency and T is the sampling period) is given by a primary cyclic digital filter consisting of adders 43-45, multipliers 35-38, and registers 50 and 51 for delay of one sampling period, and the discrete Fourier conversion is executed to output outputs of a real part and an imaginary part to terminals 21r and 21i, respectively. These outputs are squared by multipliers 33 and 34, respectively and are added by an adder 42 to transmit an output proportional to the amplitude of components of the required detection angular frequency omega to a terminal 2. On the basis of the output of the adder 42, it is discriminated whether the input signal having the required detection angular frequency omega exists or not.

Title: Variable resistor
Inventor: MAEDA RYOICHI
IPC: A63F13/218
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To improve controllability by providing a protrusion at the center of a curved surface of a conductive contact point, permitting the protrusion of the conductive contact point and the curved surface to be deformed so as to change the contacting area with respect to a resistor body pattern through the pressing control of a support member, and allowing resistance value to be variable. SOLUTION: In a variable resistor, when the upper portion of a support 6a which faces a resistor body pattern 5 is pressed, a leg 6b is imparted with elastic deformation, and further a protrusion 7b which is protruded at the center of a conductive contact point 7 firstly comes into contact with the center of the resistor body pattern 5. When the support 6a is kept pressed, a curved surface 7a comes into contact with the resistor body pattern 5 following the protrusion 7b while being deformed to gradually increase the contacting area, thereby varying the resistance value at both ends of the resistor body pattern 5.  When the support 6a is released from being pressed, the support 6a is restored to the original state by the elasticity of the leg 6b itself, and further, the contacting area of the curved surface 7a and the protrusion 7b with respect to the resistor body pattern 5 is reduced while varying the resistance value. Thus, the conductive contact point 7 is restored to the original state.

Title: Connector
Inventor: KINOSHITA YOSHICHIKA
IPC: H01R35/04
Filed: 1990-06-29
Abstract: PURPOSE:To prepare a time lag for connecting timing by differentiating connecting positions between plug contacts and socket contacts of a plurality which follow relative turning movement of a plug and a socket, every pair of them. CONSTITUTION:Socket contacts 37 are arranged along curved forms of circular arc shaped recess parts 31. This arrangement makes them so that the more thickness Wo of grooves 40 is thick, the more the socket contacts 37 get near to connecting terminal parts 24a, and the more the thickness Wo is thin, the more the contacts 37 are apart from the terminal parts 24a to the contrary. Consequently by differentiating the thickness Wo in each pair of the contacts 24, 37, connecting timing of each pair of the contacts 24, 37 can be varied according to a turning position of a socket 22. With this constitution, by differentiating connecting timing between a power source terminal and a signal terminal, the signal terminal is connected after connecting the power source terminal, thereby an integrated circuit and the like can be protected from damage while preventing noise interference.
