Title: Digital filter circuit
Inventor: HIOKI AKIRA
IPC: H03H17/00
Filed: 1993-09-16
Abstract: PURPOSE:To shorten the processing time and to simplify the constitution of a digital modulating filter which applies a table reference system to refer to a ROM. CONSTITUTION:The input coding data Xn is delayed by an extent equal to a filter tap coefficient and supplied to a shift register 0 consisting of delay elements 1-15. All product-sum operational results obtained to the tap coefficients corresponding to two continuous data (equal to two tap coefficients) are previously stored in the corresponding ROM 16-23 respectively. Then two continuous data corresponding to each other are used as the addresses of ROM 16-23, and the output data on these ROMs are added together by adders 24-30. Thus the filter output is obtained. Thus the number of adders of a filter can be decreased and also the processing time of the filter is shortened.

Title: Terminal structure
Inventor: SAKIYAMA SHOICHI
IPC: H01R4/48
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent slipping off from a case without using any locking piece for preventing a connecting plate from slipping off, by providing a pusher capable of being freely slid in relation to a case, to be engaged with the connecting plate, for regulating slipping off, and for releasing the engagement of an electric wire and the tip of a contact locking plate by pressing. SOLUTION: When electric wires 7, 8 are inserted into electric wire inserting holes 9, 10, they are brought in contact wit the tip and the intermediate part of a contact locking plate of a terminal body 11, and the electric wires 7, 8 and the terminal body 11 are electrically and physically connected to one another. When the wires 7, 8 are to be drawn from the terminal structure, the tip of the contact locking plate bites core parts 7', 8' of the electric wires, and the electric wires can not be drawn. Since the tip of a pressing and locking projecting piece presses down the tip of the contact locking plate when the pusher 23 is pressed, the engagement of the tip and the core parts 7', 8' of the electric wires is released, nothing latches the electric wires 7, 8. Accordingly, the electric wires 7, 8 can be easily drawn out.
