Abstract:
An electronic apparatus includes a wiring board, a main member to which the wiring board is fixed, a first component mounted rigidly on the wiring board and positioned with respect to the main member, and a second component mounted movably on the wiring board and positioned with respect to the main member, and a positioning portion provided on the wiring board to determine a position of the wiring board with respect to the main member, wherein a distance from the positioning portion to the first component is shorter than a distance from the positioning portion to the second component.
Abstract:
A detector for a proximity sensor, includes: a sensing portion including a pair of sensing coils which has central axes along a direction intersecting with a moving direction of a sensed object moving in a predetermined moving path and is provided so as to interpose the moving path; a circuit block including a capacitor composing an LC resonant circuit with the sensing coils of the sensing portion and provided with an oscillator which oscillates the LC resonant circuit; and an electric connector composed of first connection terminals and a first conductor pattern that connect the sensing coils of the sensing portion in series, and second connection terminals and a second conductor pattern that connect the sensing coils to the oscillator.
Abstract:
A method for remanufacturing an electronic assembly allows the assembly to be disassembled, tested and reassembled despite certain components being permanently affixed to a housing of the assembly. The electronic assembly includes a circuit assembly within the housing. During remanufacture, a first portion of the housing is removed to expose a first side of the circuit assembly and a second portion of the housing is removed to expose a second side of the circuit assembly. When removing the second portion of the housing, one of the components of the circuit assembly may also be removed. During remanufacture a connector assembly including a replacement component substantially similar to the removed component, and including one or more pins connected to the replacement component and situated to mate with one or more empty sockets of the circuit assembly is used to facilitate testing of the assembly.
Abstract:
An electronic control apparatus can be reduced in size and cost by eliminating certain component parts such as a power board, etc. The apparatus includes a housing, a heat sink, semiconductor switching elements having terminals and mounted on the heat sink, a circuit board arranged in opposition to the heat sink, conductive plates connecting between the circuit board and the semiconductor switching elements, and a cover receiving the semiconductor switching elements and the circuit board in cooperation with the heat sink. The conductive plates have the press-fit terminal portions press-fitted into the through holes in the circuit board, and the individual conductive plates are arranged along a lead-out direction in which the individual terminals of the semiconductor switching elements lead out, and are bonded to the individual terminals.

Abstract:
COVERS AN IMPROVED THIN LAYER ELECTRONIC CIRCUIT ASSEMBLY FOR RECEIVING ELECTRICAL COMPONENTS WHICH INCLUDES A NON-CONDUCTIVE FLEXIBLE PLASTIC FOIL SUPPORT HAVING A THINLAYER CIRCUIT ADHERENT TO SAID SUPPORT, WHICH CIRCUIT INCLUDES CONDUCTOR TRACKS FOR RECEIVING SAID ELECTRICAL COMPONENTS AND CONTACT SURFACES FOR CONNECTION WITH OTHER
CIRCUITS. IT ALSO COVERS A METHOD OF PREPARING A PLURALITY OF SAID ASSEMBLIES IN A CONTINUOUS MANNER BY PREPARING A TAPE OF SAID SUPPORT AND FIXING THEREON A PLURALTIY OF SAID THIN LAYER CIRCUITS IN A CONTINUOUS MANNER. THE TAPE THEN IS TRIMMED TO PROVIDE THE DESIRED GROUP OF CIRCUITS.
Abstract:
An in-line heating device (1,2,3,4) for a liquid food or beverage preparation machine in which liquid is circulated through the heating device and then guided into a brewing chamber. This heating device comprises: a thermoblock with a metal mass (1) that incorporates an inlet, an outlet and a heating chamber extending therebetween to form a passage for guiding said liquid circulating through said mass, the mass being arranged to accumulate heat and to supply heat to the liquid; and one or more electric components (60,70,75) that are rigidly secured onto or into the thermoblock and that are connected to a printed circuit board (4) and/or a flex-print (4') arranged to control the thermoblock. The electric components are rigidly connected to the printed circuit board and/or flex-print, in particular via rigid connector pins or blades or rigid plug and socket members.
