Title: Adaptive filter
Inventor: UMIGAMI SHIGEYUKI
IPC: H04B3/04
Filed: 1988-03-15
Abstract: PURPOSE:To realize a filter with comparatively less bit length and stable and high accuracy by applying round processing to the least significant bit caused in an arithmetic operation by a round processing section and applying truncating processing to the least significant bit in case of less than a prescribed value by a truncating processing section. CONSTITUTION:A DC monitor section 3 applies DC integration to an output signal of a filter section 1 and when the integration value is larger than a predetermined threshold value, that is, the value as the DC offset is larger than the threshold value, a switching section 4 connects a processing section 5 to a tap coefficient revision section 2 to apply rounding processing to the least significant bit. In a opposite case, a truncating processing section 8 is connected to the tap coefficient revision section 2. Thus, the tap coefficient revision section 2 revises the tap coefficient without being affected by the DC offset, the system stability is improved and no deterioration in the characteristic is caused. Even if the bit length is reduced comparatively, the stability is improved and no deterioration in the characteristic is caused.

IPC: H05K1/18
Filed: 1992-02-13
Abstract: PURPOSE:To solder electronic parts, electrical parts, etc., on a substrate with an excellent bonding strength while suppressing the generation of solder bridge by applying insulative coating partly on the surface of a terminal. CONSTITUTION:A tip of terminal 20 protruding from the body side face of electronic parts, electrical parts, etc., is set as a horizontal section 23 being parallel to the body surface. A rising section 22 on the section 23 is partly treated with insulative coating 24. When it is assumed that the height of the section 22 treated with no coating 24 from the section 23 is H and the thickness of the section 23 is t, respectively, the relation shall be represented by the equation, 1<=H/t<=2. Thus the melting solder is supplied efficiently into a bonding boundary between the section 23 and a land section 31, thereby preventing the melting solder from spreading to the body side through the surface of the terminal 20. Therefore, even the electronic parts, electrical parts, etc., in which many terminals are arranged in narrow clearance can be soldered without causing solder bridge, and correction works after soldering can be also reduced to a great extent.
