Abstract:
A PC card electrical connector with an expandable ejector includes an intermediate bar (10) having a cam follower pin (13); an ejector button section (20) for motion between a lock position (A2) where the ejector button section projects little more than a front end of the casing and a release position (C2) where the ejector button section projects far from the front end of the casing; a line spring (28) having a cam follower end (30); a first biasing spring (30) for biasing the ejector button section forwardly so that when the ejector button section is depressed a first time to release the follower end of the line spring from the lock position, the ejector button section is brought to the release position; and a second biasing spring (49) for biasing the intermediate bar onto a side of the ejector button section so that when the ejector button section is moved forward to the release position, the intermediate bar is turned to connect to the ejector button section, thereby making it possible that by depressing a second time the ejector button section to move the intermediate bar rearwardly, the receiving plate is brought to the removing position for removal of the PC card.
Abstract:
A PC card electrical connector includes a case (40); an ejector (20) having a front button (21) and a rear arm (22); a first spring (27) for forwardly biasing the ejector; an intermediate bar (10) for abutment with the ejector having a cam follower (13); a second spring (49) for biasing the intermediate bar toward the rear arm of the ejector; an ejector bar (5) for abutment with the intermediate bar; a cam member (63) movable on the bottom of the case and having an engaging portion; a first cam channel (I) provided on the ejector so as to engage the cam member such that when a PC card is inserted, the engaging portion is held at a lock position where the ejector button is held at a depressed position and, when the ejector button is depressed, the engaging portion is released from the lock position and, when the ejector button is depressed again, the ejector is moved to a projected position while the engaging portion is returned to the lock position; and a second cam channel (II) provided on the bottom of the case so as to engage the cam follower such that upon first depression, the intermediate bar is placed against the rear arm and, upon second depression, the intermediate bar is brought to the position opposed to the ejector, thereby enabling to eject the PC card from the receiving slot.
Abstract:
A PC card electrical connector which includes a housing having at least upper and lower storage cavities for accepting PC cards (1) one for each storage cavity; at least upper and lower movable plates (2) disposed near the upper and lower storage cavities, respectively, each movable plate having at least one abutment member (2A) for abutment with a portion of the PC cards; at least upper and lower eject levers (5) rotatably supported by the housing in planes parallel to the PC cards and coupled at one end to the movable plates; at least upper and lower intermediate bars (6) coupled to the other end of the upper and lower eject levers, respectively, and movable along sides of the storage cavities; and an ejector (8, 9) for selectively engaging and pushing one of the upper and lower intermediate bars, thereby permitting operation of one of the eject levers to eject the desired PC card with ease and few errors.
Abstract:
An electrical connector has a plurality of sheet-type terminals (20 and 30) which are received into corresponding receiving slots (11 and 12) of a housing (10) and are arranged parallel each other in a direction. The terminals (20, 30) have connection sections (23 and 33) at their ends, which are arranged so as to face the same side and protrude outward from a bottom surface of the housing. The movable member (40), which presses a flat cable (C) toward contact sections (26, 36), is movably supported at an open mouth of the housing (10). The connection sections (23 and 33) have connection surfaces (23A and 33A) for contact with circuit sections of a circuit board, which are staggered in a receiving direction of the terminals to the housing.
Abstract:
An electrical connector connection system for connecting a pair of receptacle connectors (10) comprises an intermediate board (20) which interconnects the receptacle connectors (10) and has signal and ground connection portions (21 and 22) on opposite edges thereof and signal transmission portions (24) for interconnecting corresponding signal connection portions (21) and a ground transmission portion (23) for interconnecting the ground connection portions (22).
Abstract:
This invention relates to new antibiotic substances B-41, a process for producing the antibiotic substance B-41 by culturing in a medium a B-41 producing strain belonging to the genus Streptomyces and then recovering the resulting B-41 from the cultured substance, and an insecticidal and acaricidal composition containing novel antibiotic substances B-41 as an active ingredient.
Abstract:

The present invention is characterized in comprising, in wt %, Fe: 0.1 to 0.6%; Si: 0.02 to 0.2%; Cu: 0.001 to 0.02%; Zn: 0.01 to 0.1%; Mg: 0.005 to 0.1%; Ti: 0.001 to 0.05%, and the remainder Al and inevitable impurities, and an average value of the crystal particle size is 60 μm or less in a direction perpendicular to the rolling direction.
Abstract:
A surface contact card connector which includes a base section 2 made of an insulating material; a cover section 3 made of an insulating material and attached to the base section at a rear end for rotation between open and close positions; first and second engaging side walls 7 and 15 provided on opposite sides of the base and cover sections, respectively, such that when the cover section is closed, they are opposed to each other; first or second engaging side walls are flexible laterally; engaging windows or depressions 9, 10 being provided in the first or second engaging side walls; engaging and releasing projections 16 and 17 provided on the second or first engaging side walls such that when the cover section is closed, they flex the first or second side walls laterally and engage the engaging members; the engaging projections having a rectangular triangle shape whose upper side 16A is substantially at right angles to the engaging side walls while the release projections being provided at positions flexible with respect to the engaging projections when the cover section is opened.
Abstract:
A valve assembly for automatically controlling the flow of a fluid comprises a casing having formed therein a first chamber, a second chamber normally communicating with the first chamber and a pressure chamber in constant fluid communication with the second chamber. Means in the form of a bellows or piston is disposed in the pressure chamber to operate a valve member such that communication between the first and second chambers is interrupted upon the increase of the fluid pressure in the latter beyond a normal level.
Abstract:
New antibiotic substances are obtained by culturing a strain belonging to the genus Streptomyces and by recovering said substances from the culture material. The new antibiotic substances possess insecticidal and acaricidal properties.
