Patent application numberDescriptionPublished
20090040737PORTABLE DEVICE FOR TRANSMITTING SIGNAL - A portable device includes an operating part, a circuit board, and a case body for housing the operating part and the circuit board. The circuit board has a circuit section configured to transmit a signal to an external device. A terminal electrode and a pair of switch electrodes are disposed on the circuit board. The terminal electrode supplies electricity from a power source to the circuit section. A switch element is configured to electrically couple the pair of switch electrodes in accordance with an operation of the operating part. A resin member is disposed on the circuit board in such a manner that the circuit section is covered with the resin member and the terminal electrode and the pair of switch electrodes are exposed to an outside of the resin member.02-12-2009
20090086445ELECTRONIC CIRCUIT DEVICE AND METHOD OF MAKING THE SAME - A method of making an electronic circuit device includes expelling air from a gap between a circuit board and an electronic element mounted on only a first side of the circuit board by filling the gap with a filling member, placing the circuit board in a mold cavity such that a second side of the circuit board is held in close contact with an inner surface of the cavity. The method further includes encapsulating the circuit board with a resin material by injecting the resin material into the cavity.04-02-2009
20090086446ELECTRONIC CIRCUIT DEVICE AND METHOD OF MAKING THE SAME - A method of making an electronic circuit device includes placing a circuit board in a cavity of a mold such that one side of the circuit board is held in close contact with an inner surface of the cavity, and encapsulating the circuit board in a casing by filling the cavity with a resin material. The one side of the circuit board is exposed to one side of an outer surface of the casing to define part of the one side of the outer surface of the casing. The method further includes thinning the casing by machining the entire one side of the outer surface of the casing.04-02-2009
20090086447ELECTRONIC CIRCUIT DEVICE AND METHOD OF MAKING THE SAME - A method of making an electronic circuit device includes preparing an electronic element having at least one projection, mounting the electronic element on only a first side of a circuit board in such a manner that the projection is substantially held in point contact with the first side of the circuit board to form a gap between the circuit board and the electronic element, placing the circuit board in a mold cavity in such a manner that a second side of the circuit board is held in close contact with an inner surface of the cavity. The method further includes encapsulating the circuit board in a casing by filling the cavity with a resin material so that the gap is filled with the resin material.04-02-2009
20100206704Electronic key - An electronic key includes a case having therein an internal space; a circuit board including a transmit portion for transmitting a radio wave, a control portion for outputting a control signal for instructing the transmit portion to send the radio wave and an internal switch for instructing the control portion to output the control signal; a waterproof cover for protecting the circuit board; an external switch configured to be bent when being pressed by a user; and a flexible sheet arranged between the waterproof cover and a surface of the circuit board on which the internal switch is arranged. The circuit board, the flexible sheet, the waterproof cover and the external switch are arranged in series in the internal space. The internal switch receives a press-force by the user from the external switch via the waterproof cover and the flexible sheet.08-19-2010
20100242273Method of producing electronic device - A method of producing an electronic device includes a molding of a first casing to seal a first face of a circuit board and electronic parts mounted on the first face. The producing method further includes a mounting of electronic parts on a second face of the circuit board opposite from the first face, after the molding of the first casing is finished. The producing method further includes a molding of a second casing to seal the second face of the circuit board and the electronic parts mounted on the second face. The molding of the second casing integrates the first casing and the second casing with each other.09-30-2010
20100246146Electronic device and method of producing the same - A method of producing an electronic device includes a holding of a circuit board and a decoration sheet in a cavity of a mold, and a filling and solidifying of thermosetting resin in the cavity. A casing is molded by the solidified thermosetting resin so as to seal electronic parts and a first face of the circuit board having the electronic parts. Further, the decoration sheet is integrated with the casing by the solidified thermosetting resin. An outer surface of the casing is defined by a second face of the circuit board opposite from the first face and the decoration sheet.09-30-2010

20110241830Portable transmitter - A portable transmitter has an inner cover, an outer cover, outer knobs, a cover, a circuit substrate, etc. The cover has projection parts made of elastic material. Each projection part projects toward a corresponding opening part of the outer cover through a corresponding penetration hole of the inner case. The front end of the projection part is contacted to the corresponding outer knob. The opposite part of the projection part is contacted to a corresponding tact switch formed on the circuit substrate while the projection part is elastically deformed and the inner case accommodates the cover. Each of the outer knobs is placed in the corresponding opening part of the outer case while the outer peripheral part of the outer knob is pushed onto the outer peripheral part of the wall surface of the opening part formed in the outer case by repulsive elastic force applied from the cover.10-06-2011
