Abstract: A contactor is used for testing an integrated circuit electronic component provided with a plurality of electrodes. The contactor includes an insulating base material provided with holes formed at positions corresponding to the electrodes, a first conductive layer having contacts which are plastically deformed portions of the first conductive layer, and reinforcement members provided on the contacts on a first surface of the contacts. The first surface of the contacts is facing towards the holes. The contacts are provided at positions corresponding to the electrodes for enabling an electrical connection to the electronic component and are protruded from the insulating base material.

Abstract: The present invention relates to an instrument for the implant of a surgical plate for osteosynthesis, comprising a rod that slides inside a tubular sleeve subject to the action of a return spring, which ends with a circular handle in the rear part and with a point with lateral cut in the front part, whose opening is closed by a small tooth located at the end of the tubular sleeve.

Abstract: An objective of the present invention is to provide a motor compressor that reduces noise by lessening a contact area between a stator and a shell, wherein a motor element is constituted of a stator having a stator core that contacts and is fixed to an internal wall of the closed vessel, and a rotator having a magnetic substance, which is attached to the rotating shaft and is rotatably supported in the inside of the stator construct. It is essential that H<Ho is satisfied wherein H is a dimension in a rotating shaft direction of an area in which the stator core contacts the closed vessel and Ho is a dimension in a rotating shaft direction of the stator core.

Abstract: A cap with a double function ring is provided, which furnishes the features of showing it has been opened and of being child proof. The ring comprises two pieces of the same size joined to the cap. One of the pieces will be released from the cam when opening the container is attempted, the other piece will remain joined to the cap, when the container is being opened, it will be necessary to press two opposite ends of the double function ring, for the purpose of releasing the movement preventing elements.

Abstract: A chemical supplying apparatus includes first and second mixing tanks for mixing and supplying chemical slurries used in a semiconductor fabrication process. The slurries are alternately provided from the first and second mixing tanks such that the slurry is continuously available to a processing apparatus for maximum efficiency. While one of the tanks is supplying the slurry, the other tank is cleaned and then used to prepare a new batch of the slurry.

Abstract: A continuous paper treating apparatus is provided which includes a tractor for feeding continuous paper and a paper treating unit for treating the paper. The tractor includes a driving belt provided with tractor pins, a tractor lid for covering the driving belt, a support base having a paper support surface for supporting the continuous paper. The tractor also includes a presser member supported by the tractor lid. The presser member is variable in position and posture relative to the tractor lid, and has a pressing surface for pressing the paper. In the tractor, use is made of springs for urging the presser member toward the paper supporting surface, so that the pressing surface presses the continuous paper onto the paper supporting surface.

Abstract: The present invention relates to an ink supplying apparatus capable of achieving labor-saving of the cleaning operation and shortening of the working time at ink replacement or the like in a printing press. This ink supplying apparatus is equipped with an ink tray provided in the interior of an ink fountain and having a bottom plate which covers upper surfaces of ink keys, and further equipped with a deflection restraining structure for supporting the bottom plate from below to restrain the deflection of the ink tray.

Abstract: The method of manufacturing a semiconductor device includes the steps of forming copper wiring; reducing an oxide film on the surface of the copper wiring by heating the copper wiring to a temperature in a range of 250° C.-450° C. under reductive gas or by treating the copper wiring in plasma of reductive gas; and then forming a film of a material not containing oxygen on the copper wiring without exposing the copper wiring to external atmosphere, and can provide a semiconductor device with good copper wiring.

Abstract: The ink jet printer head comprises: a piezoelectric device 10 including a stress removing electrode 14, a stress removing piezoelectric layer 16 formed on the stress removing electrode 14, and a drive layers formed of drive electrodes 18 and a piezoelectric layer 20 formed on the stress removing piezoelectric layer 16, the drive layer being divided in a plurality of drive portions 222 and a plurality of non-drive portions 26 by grooves 24 which arrive at the stress removing piezoelectric layer 16; and a channel plate 40 jointed to the piezoelectric device 10 and having discrete ink channels 42 formed in parts thereof opposed to the drive portions 22, corresponding to nozzles for jetting ink.

Abstract: A roll bar for vehicles, in particular for topless motor vehicles, which can be fixedly or retractably attached to the vehicle. The roll bar is of a shell type construction having at least one main substantially flat surface provided with shaped convex portions having shape, size and geometrical arrangement to withstand a plurality of different load directions and/or kinds of load acting on it in the event of an accident.
