Abstract: A device for draining engine oil in a DIY manner including an oil drain screw bolt, a valve, an oil drain tube, a spring element, and a control cable. The screw bolt has a cylindrical rod portion having a drain hole at the center, and a head portion having an oil outlet at one side communicating with the drain hole. The outer end of the oil outlet forms a threaded section of a larger diameter. The head portion is provided with a through hole in a direction perpendicular to the oil outlet. The valve is provided with a rod at a front end for receiving a spring. A front end of the rod is connected to a pull strap. The valve is locked in the through hole of the screw bolt by a sunk-head screw. The oil drain tube has a rotary connecting portion at a front end for locking in the threaded section of the oil outlet. A control valve is provided at a rear end of the oil drain tube. The control cable forms a hook portion at a front end thereof and is passed through a small duct at one side of the oil drain tube.

Abstract: A hockey stick has a reinforced hockey blade which is equipped with a plastic bumper secured to the bottom edge thereof and a layer of glass fiber is coated on the surface of the blade by heat hardening art. Such processed hockey stick is flexible and durable against violent impact or collision in operation, making the operation life thereof longer.

Abstract: A hard diskdrive address adjusting device is provided which includes a plurality of rotary binary DIP switches respectively mounted on the hard diskdrives of an array hard diskdrive system. The rotary binary DIP switches adjust the address of each hard diskdrive. Each hard diskdrive of the array hard diskdrive system has a plurality of jumper terminals arranged in two rows, the jumper terminals of one row being connected in parallel with the contact C of the respective rotary binary DIP switch. The jumper terminals of the other row of each hard diskdrive being respectively connected to corresponding contacts of the respective rotary binary DIP switch.

Abstract: A conductive polyester sheet having three layers, comprising one substrate layer and two surface layers, laminated together by co-extrusion is provided. All the three layers are made from polyester and/or copolyester, and the surface layers further contain carbon black and thus are useful as conductive layers. The sheet has a surface conductivity of not more than 10.sup.8 ohms and the flow index of the material for the conductive layers during the extrusion step is not lower than 60 g/min (loading, 2160 g; temperature, 275.degree. C.).

Abstract: A mechanism of a band attaching device of a case sealing machine for preventing the band from falling down. A fourth band guiding wheel is disposed under the band stopper boards and movable on the front band pressing wheel support. When the fourth band guiding wheel is positioned at a lowest position, the front edge of the outer surface of the fourth band guiding wheel intersects the band stopper boards and the band is forced to move downward and linearly contact with the band stopper boards on the adhesive face. At this time, the band is urged to forward project into an arch state so as to enhance the upright standing ability of the band without falling down.

Abstract: A kick-activated wearable alarm for infants is provided that includes three temperature sensors and a main controller unit installed in a belt pack. The belt pack is directly worn around the abdominal section of an infant and operates in conjunction with an external receiver, whereby the disclosed structure offers total kicking and fever sensing performance. The belt pack is installed around the abdominal section of an infant with two of the three sensors respectively placed in an exposed state at the anterior and posterior aspects of the abdominal section and the other sensor being placed inside the clothing of the infant. Whether the infant kicks while asleep or awake, or when a fever develops that raises body temperature, the three temperature sensors are connected to a conductor interfaced to the main controller unit. The main controller unit transfers the sensed signal to an external receiver, which emits of an audible alarm.

Abstract: A modular dust collection plate assembly (10) for use in an electrostatic precipitator is provided. The dust collection plate assembly (10) includes at least one panel member (100) and at least one waveform member (200) releasably coupled together. The panel member (100) is characterized by a substantially planar contour, having first and second faces on opposing sides thereof which are commonly bounded laterally by a pair of lateral edge portions (110, 110) extending in a longitudinal direction. The waveform member (200) also extends in the longitudinal direction and is characterized by a predetermined curvilinear cross-sectional contour that enables the waveform member (200) to disrupt at least a portion of the gaseous flow that would pass across it during operation in an electrostatic precipitator.

Abstract: A tea maker structure is disclosed. It includes a percolator cup as an upper layer of the tea maker and a tea cup as a lower layer of the tea maker. A bottom of the percolator cup is formed with a water outlet communicating with the tea cup. A filter mesh is disposed above the water outlet to prevent tea grounds from blocking the water outlet. The opening/closing of the water outlet is controlled by a controlling mechanism coaxially disposed in the percolator cup, whereby the tea can flow into the tea cup with the tea grounds remaining in the percolator cup. Also, this tea maker is prevented from falling down due to improper application.

Abstract: A prong structure of a plug is made from a rectangular unfolded strip which decreases waste material to a minimum during manufacture. The prong is formed by doubling over the rectangular strip with a lateral base portion formed at the bottom of both sides thereof. One wing of the lateral base portion of the prong is a lateral tie segment with a clip formed at the end, in which the clip is folded to form a U-shaped groove along the short side of the rectangular strip, for fixing a cord therein by closing the groove from both sides. The other wing of the lateral base portion of the prong is a lateral supporting lug, in which a tongue shaped assistant lug is punched out at the root, so that is can be bent to the clip side to fill the space left by a folded portion of the clipping lug to form a stable supporting base.

Abstract: An improvement in a pepper grinder. The pepper grinder comprises a housing element and a grinding mechanism housed inside the housing element. The improvement lies in a fixing element provided for fixing the grinding mechanism to the housing element, which fixing element has two opposing hooked portions each having a sloping part and a second part with an enlarged part. The grinding mechanism has two gaps narrower than the enlarged parts. The gaps engage upper ends of the second parts which are arranged just above the enlarged parts and the sloping parts are firmly abutted against an inner wall of the housing element whereby firmly fixing the grinding mechansim to the housing element.

Abstract: A light bulb holder assembly includes a base connecting with a cap having engaged with a light bulb wherein a groove is formed on the cap and a plate is provided in the base which can be engaged within the groove of the cap when the cap being engaged within the base to separate a set of a conducting wire and a conductor from another set that provides two independent areas for infiltrating water drag and prevents from resulting in a short circuit.
