Granted: 1995-09-25
Abstract: At least one electronic element (12) is ultrasonically welded to a printed circuit board (10) to create the electronic circuit. Proper alignment between terminals of a conductive circuit pattern (14) on the circuit board and terminal units (20) on the connecting surface of the electronic element is ensured by a variety of techniques: (i) small protuberances (22) on the terminal units, (ii) raised section (26) on the bottom surface of the terminal units placed to engage indented portions of the board, and (iii) corresponding posts (36) (on the electronic elements) and holes (41) (formed on the circuit board). The ultrasonic welding of the element to the printed circuit board is typically conducted at a frequency range between 25-30 megahertz which produces a vibration which grinds the terminal units of the electronic element to the terminals of the circuit pattern while also welding the element and circuit board together. Electronic circuits formed in accordance with the inventive concept disclosed herein can be comprised of stacked or interlocking combinations of weldable electronic elements. Such structures can improve rigidity and vary spacial relationships of electronic circuits. <IMAGE>

Abstract: The hydrofoil craft comprises a couple of wave ploughs (1) installed in the lower part of a hull (4), bow and stern hydrofoils each of which is supported to the hull by a couple of struts (3) and equipped with an individual lift flap (5-a, 5-b), and a couple of hydraulic pumps (7) with a piston (8) for controlling the bow and stern lift flaps. The hydrofoil system with the struts is connected to the hull by a flange connection method.

Title: Diamond-resin wheel manufacturing method for grinding
Inventor: JO KYONG-YANG
IPC: B24D3/00
Filed: 1992-12-22
Granted: 1995-05-18
Abstract: The method is for mass-producing the diamond resin wheel, specially used for high-precision grinding of crystal oscillators, Brown tubes and others. The diamond resin wheel production method comprises the steps of: heating the mixture of heat-hardening resin and synthetic diamond powder; crushing the hardened mixture; molding the crushed particles of the hardened mixture and an elastic resin.

Title: Global communication system, receiver and method for operating the same
Inventor: DAVIS WALTER LEE
IPC: H04B7/185
Filed: 1992-05-02
Granted: 1996-07-10
Abstract: A global communications system is described having terrestrial transmitters (1108) for transmitting coded message signals in each of a plurality of geographic areas (1102, 1104, 1106). The global communication system further includes at least one satellite transmitter (1114) for transmitting the coded messages signals in each of a plurality of global geographic areas. The coded message signals transmissions include channel identification codewords identifying the terrestrial channels and the satellite channel. The terrestrial channel is selected for operation when the channel identification codeword received matches a first predetermined channel identification codeword. The satellite channel is selected for operation when the channel identification codeword does not match a second predetermined channel identification codeword. The terrestrial channel is periodically reselected when the channel identification codeword received on the satellite channel matches the second predetermined channel identification codeword.

Title: Stereo and dual voice detecting system
Inventor: KOO SEUNG-YEUP
IPC: H04B1/16
Filed: 1993-01-21
Granted: 1996-10-14
Abstract: The circuit includes a FM detection means(100) for reading the second middle frequency and detecting a FM, a band pass filter(200) for filtering an output signal, an envelope detection means(300) for detecting an envelope, an amplifier(400) having a positive input port, the first resistance(500), the second resistance(700), a phase difference means for detecting phase of output signal and stereo/dual speech recognition signal, and a low pass filter(1000) for reading a phase-difference and filtering a low-band.
