Abstract:
When one shielded connector is engaged with the other shielded connector, a conductive connector housing of the one connector is electrically connected to a conductive connector housing of the other connector to establish shield connection. Either one of the connectors has a conductive rotating lever, while the other connector has an engaging portion for engaging with the rotating lever to connect the shielded connectors by rotation of the rotating lever. A conductive resilient abutting member, which abuts on the rotating lever and/or the other connector housing to be resiliently deformed when the connectors are connected with each other by rotation of the rotating lever, is provided on the rotating lever and/or the other connector housing.
Abstract:
A low-cost shield connector 1 connecting smoothly with a mating connector includes a connector housing 20, a terminal 21, an inner housing 22, a spacer 23 and a lance 42. The connector housing 20 is formed into tubular shape. The terminal 21 is joined to a shield wire 29. The inner housing 22 receiving the terminal 21 is received in the connector housing 20. The spacer 23 to be mounted in the inner housing 22 prevents the terminal 21 from coming off from the inner housing 22. The lance 42 formed integrally with the inner housing 22 is locked in the connector housing 20.
Abstract:
A CFI-type zeolite where the atomic ratio of silicon to the heteroatom is 45 or less and the long axes of the crystals are 0.7 &mgr;m or less is useful as a catalyst for conversion reaction of aromatic compounds because the zeolite has a number of active sites and small crystals.
Abstract:
A down-sized pressure sensing semiconductor device with improved EMI tolerance as compared with conventional ones is achieved. A metal substrate (11) has a through hole (12), in which a cylinder (9b) of a pressure leading-in tube (9) is inserted, and is fixed to a flange (9a) of the pressure leading-in tube (9). A control circuit component (13) for controlling a semiconductor chip (1) is disposed on the metal substrate (11). On the metal substrate (11), a connector electrode (14) is further provided which establishes electrical connections between the pressure sensing semiconductor device and external circuits. Further, a metal cover (17) in the shape of a connector leading to external circuits is soldered to the metal substrate (11) to cover the semiconductor chip (1) and the control circuit component (13) together with the metal substrate (11). The cover (17) is electrically connected to a conductive wire (e.g., a ground wire) formed on the metal substrate (11).
Abstract:
An impact load effected on the single body of an acceleration sensor device is absorbed with a relatively simple construction, thereby protecting a semiconductor sensor element provided in the sensor. The acceleration sensor device comprises a semiconductor sensor element 2 which can sense an acceleration in a direction perpendicular to its principal plane, a base plate 3 which supports the sensor element 2, a package 11 which supports the base plate 3 and encloses the base plate 3 and the sensor element 2, a frame 12 which has a plurality of leg sections 12d protruding from a bottom plane of the package 11 and is fixed on the package 11, and a cap-shaped resin cover 13 which has a roof section 13a opposite to an upper surface of the package 11 or the frame 12 and covers the package 11 from above as fixed on the package 11, and a side wall section 13b of the cover 13 extends at least to a position corresponding to a place where the sensor element 2 is arranged.
Abstract:
A semiconductor acceleration sensor includes a substrate, a semiconductor sensor chip with a diaphragm and having one end fixed to a pedestal, the pedestal including at least one thick film layer and disposed on the substrate, and a protrusion of at least one thick film layer on the substrate directly opposite a free end of the sensor chip, shorter than the pedestal. The protrusion protects the semiconductor sensor chip from breakage at the diaphragm due to impacts.
Abstract:
This invention relates to mixtures of molding sand which comprise a mixture of a molding sand with a rapid hardening cement containing calcium aluminate as amorphous glass and/or crystals, and/or calcium haloaluminate, a polymer water holding agent and a lime, or mixture of a molding sand with the above-mentioned rapid hardening cement, a polymer water reducing agent, a lime, and, if necessary, a foaming agent, and in either case with water. The mixture also provides a method of mixing the ingredients except for water and then kneading the mixture with water.
Abstract:
This invention relates to a method for retarding the setting time of rapid hardening cement which comprises adding a boric compound to cement manufactured by adding insoluble anhydrite to clinker powder containing 11CaO.7Al.sub.2 O.sub.3.CaX.sub.2 or adding the clinker to insoluble anhydrite and intergrinding the mixture, and a method for still more retarding the setting time of rapid hardening cement which comprises adding a boric compound to cement containing a set-retarding agent other than the boric compound.
Abstract:
A shielding structure for a wire harness includes a seal member which has a wire through hole that allows the wire to pass therethrough while sealing a circumference of the wire. The wire has a structure where an insulating resin layer is formed on an outer circumference of a conductor, and a predetermined range in a length direction of the conductor is coated with a shield layer formed by resin plating to cover an outer circumferential surface of the insulating resin layer. A terminal portion of the wire is passed through the wire through hole of the seal member to be introduced into the shield wall to a position where the shield layer exists, whereby an inner circumference of the wire through hole is made in close contact with the shield layer to cause the shield layer and the seal member to be electrically conducted with each other.
