Abstract: A card connector includes a housing having a receptacle to receive therein a card in an insertion direction and the card has a terminal member. A connection terminal is secured to the housing and is configured to contact the terminal member of the card. A card ejecting action detecting switch is configured to detect when the card is ejected from the housing. A card guide mechanism is provided with an urging member for urging the card in a direction opposite the insertion direction. The card guide mechanism is configured to hold the card at a locked position to ensure that the terminal member of the card is in contact with the connection terminal and to permit movement of the card in the opposite direction by a pushing force exerted on the card in the insertion direction. The card guide mechanism ejects the card after performing a pushing action on the card a plurality of times.

Abstract: A FPC connector has an insulative housing with a general U-shape that defines an opening that receives a free end of a length of FPC. The housing has a base and two leg portions and the leg portions have engagement arms that hold engage the FPC free end when inserted into the connector housing opening. A cover of the connector housing has press members that press the FPC and dielectric barriers thereon into contact with contacts on a circuit board.

Abstract: A connector for joining together two lengths of FPC or FFC-type cable has a housing (31) and two FPC-cable-receiving slots (33) formed therein, on the same side of the housing. The slots are disposed in the housing on opposite sides of an axis of symmetry, and the slots each contain a plurality of conductive terminals (41). The terminals each have a fixed contact beam (43) spaced apart and aligned with a moveable contact beam (44). The contact beams flank each of the cable-receiving slots and are pressed into contact with contact portions of the FPC cable by actuators (11) that are moved in opposite directions. The actuators spread the contact beams apart in response to movement in one direction and urge them toward each other in the other direction.

Abstract: A method of making semiconductor devices which enables control of the impurity concentration and fine patterning by making removal of residual stress due LOCOS oxidation compatible with the formation of deep wells. A selective oxide layer is formed for separating element regions on a principal plane of a semiconductor substrate, for example, a p.sup.- -type silicon substrate 1. A mask is formed (for example photoresist 47) on the surface including the selective oxide layer and impurities (for example phosphorous) of a conductivity type opposite that of the semiconductor substrate are introduced via an opening in the mask. Then the selective oxide film is annealed by a high-temperature treatment while a deep well (for example n-type deep well 50) is formed by introducing the impurities.

Abstract: The present invention relates to a print head assembly for use in an ultrasonic printer. The print head assembly comprises at least one print head which is slidably mounted in a block which is slidably secured in the ultrasonic printer. Each print head comprises an ultrasonic vibrator, a horn coupled to the ultrasonic vibrator for amplifying energy generated by the ultrasonic vibrator, and a print head wire coupled to the horn. The print head wire has a tip which forces an ink ribbon into engagement with a print medium and against a platen in the ultrasonic printer in order to print a pixel thereon. A pressurizing mechanism contacts the block and forces the tip of the at least one print head against the ink ribbon and the print medium and against the platen with a predetermined force in order to print at least one pixel on the print medium.

Abstract: A wire guide tip in a wire dot printer is made of ceramic and is integrally formed with the front wire guide and inserted during mold processing of the front wire guide.

Abstract: A moving piezoelectric type crystal element drives a print wire in the direction of a platen and against the resilience of return spring and a rebound spring. A voltage pulse is applied through a conductor and across the piezoelectric element to cause displacement or elongation strain thereof to drive the print wire into impact with the platen and upon impact of the print wire a voltage pulse is generated across the piezoelectric element which generated pulse is recovered through the conductor.

Abstract: A piezoelectric crystal element is resiliently urged to a home position and drives a plunger member and a print wire in printing operation. Upon rebound movement, the crystal element contacts a step portion of the print head housing to inhibit oscillation of the crystal element more rapidly than oscillation of the plunger member.

Abstract: A ribbon stabilizer or guide member is provided in a ribbon reversing section of a ribbon cassette to prevent adverse twisting of the ribbon and to correct irregular twisting thereof and to maintain the normal reverse action or operation of the ribbon in its travel through the cassette.

Abstract: A ribbon cassette with re-inking mechanism includes a removable ink supply tank having a low density ink element and a high density ink element, and an ink transfer roller engaging the high density ink element and having an uneven surface on the periphery thereof for carrying ink in controlled manner from the high density ink element to the ribbon.
