Abstract: In this traction drive tool adapter, a rotary portion (A) has an inner housing (1) at its front half with bores (5) for the insertion of planetary rollers (7), extending radially from the outer circumferential surface of the housing into a central bore (4) therein. Each of the roller-inserting bores (5) has grooves (6,Fig. 2) for the drive pins (8) of the planetary rollers (7), these grooves continuing from the two axially opposite ends of the roller-inserting bore. Each drive pin (8) with its planetary roller (7) may thus be set into the front half of the rotary portion (A) by inserting the planetary roller (7) from radially outside, the ends of the pins (8) fitting into the shaft-member-setting grooves (6). The rotary portion (A) can therefore be in one piece. The outer circumferential section of each planetary roller (7) is engaged with an annular fixed track (32) in a fixed portion (30) of the adapter and the outer circumferential section of a sun roller (52) on the tool mount portion (50) of the adapter. A thread (24a) may be provided in a through bore (24) extending from the rear end of the rotary portion (A) to the central bore (4) in the axial direction, with a screw (25) engaged with the thread. This assists removal of the tool mount (50). Labyrinth seals (18,35,53) may be provided at the outer ends of the relative rotary regions between the fixed, rotary and tool mount portions, with elastic contact lip-carrying rings (19,20,21) fitted on the inner side of the labyrinth seals.

Abstract: An integrated circuit having a normal operating mode and a special operating mode, such as a special test mode, is disclosed. The special test mode is enabled by a series of signals, such as overvoltage excursions at a terminal, rather than by a single such excursion, so that it is less likely that the special test mode is entered inadvertently, such as due to noise or power-down and power-up of the device. The circuit for enabling the test mode includes a series of D-type flip-flops, each of which are clocked upon detection of the overvoltage condition together with a particular logic level applied at another terminal; multiple series of flip-flops may be provided for multiple special test modes. Additional features include the provision of a power-on reset circuit which locks out the entry into the test mode during power-up of the device. Acknowledgment of the entry into test mode is provided by the presentation of a low impedance at output terminals while the device is not enabled ; chip enable of the device causes the device to exit the test mode. Once in test mode, the output enable terminal of the device can provide a chip enable function.

Abstract: Melt blown die apparatus are provided for producing a fibrous web from a polymer material. The apparatus include die means for providing a molten stream of the polymer material and primary gas means having primary gas discharge channel means 30 for providing a pressurized gas at an exit end of the die means. The primary gas discharge channel means further includes gas lip means 14 for directing a portion of the pressurized gas to the molten polymer stream. Spacer bar means 16, 18 are also provided for determining a fixed spacing between the exit end of the die means and the gas lip means. This fixed spacing is substantially preset during assembly of the apparatus for a given range of apparatus operating temperatures and flow rates of the pressurized gas. This invention has been demonstrated to provide increased slot widths and set backs for extremely high exit gas flows approaching Mach 0.8. The invention also substantially eliminates centering offsets and dimensional instability associated with adjustment screws previously used for determining the spacing between the exit ends of the gas discharge channels and the die.

Abstract: A shock absorber (38) is adapted to be disposed within a perforating gun string (32) or within the tubing string above the perforating gun (30) and includes an energy absorbing element (16,18) adapted to absorb and store mechanical energy during detonation of the perforating gun and to permanently deform in response to the storage of the mechanical energy, the stored energy being released in the form of heat, and not in the form of kinetic energy. Therefore, following absorption of the mechanical energy by the shock absorber, no further expansion of the shock absorber is experienced. The shock absorber includes an inner housing (12), an outer housing (10), a connection (14) for interconnecting the inner and outer housing, and a break up charge (20) for breaking the connection and releasing the inner housing from the outer housing when the perforating gun is detonated whereby the shock absorber is as strong as the tubing string before the connection is broken and is flexible after the connection is broken. The energy absorbing element (16,18) may be a damping coil or it may be a honeycomb. The damping coil and honeycomb energy absorbing elements permanently deform when mechanical energy is absorbed; therefore, the stored mechanical energy is subsequently released in the form of heat and not in the form of kinetic energy.

Abstract: The invention relates to a lubricating device for the tool shank end of a fluid-driven impact hammer, by means of which lubricating grease can be applied to the guide supporting the tool shank end at one location or at several successive locations via lubricating passages leading into the guide and connected to a lubricating-grease feed. With the invention the proposal is made for a configuration of the lubricating passages (25a to d, 26a to d) in which they together have a throttling resistance graded in magnitude. This throttling resistance is proportioned as a function of the position of the relevant lubricating passage with regard to the lubricating-grease feed (14) in such a way that it in each case decreases from lubricating passage to lubricating passage with increasing length of the feed path to be covered by the lubricating grease. <IMAGE>

Abstract: A liquid crystal display device with a high quality, where there is no flickers or nonuniformity of brightness in a display image. Level shifts (AV1), (AV2) of a pixel electrode potential (Vs), which is caused by parasitic capacitances between a drains and source electrodes, and between a gate and source electrodes of a TFT element, results in the flickers or nonuniformity of brightness. A storage capacitor line voltage generating circuit and a storage capacitor line driving means for applying a storage capacitor line voltage (VH) to a storage capacitor line suppress change of a liquid crystal applying voltage caused by change of electric potential difference, or the level shifts (AV1), (ΔV2). This reduces, and further disappears the change of the liquid crystal applying voltage.

Abstract: A point-of-load power supply employs a linear series regulator between a dc source and a resonant forward converter to achieve high bandwidth and to minimize magnetic and energy-storage components. The linear series regulator is controlled by the power supply output voltage in such manner that the linear series regulator regulates the output voltage over a high bandwidth. In one embodiment, a capacitor-multiplying, dual resonant forward converter is employed wherein a relatively high-voltage, energy-storage capacitor is coupled in parallel between the input dc power source and the converter. The converter is controlled such that one of the transformers is always coupled to the output so that energy is stored on the relatively high-voltage side of the converter, and the value of the energy-storage capacitance is reduced. In distributed power systems wherein the dc input voltage is provided by another centralized power supply such that the dc input voltage is fairly well regulated, a low-overhead series regulator (e.g., an n-channel FET) can be used in order to further increase efficiency. Alternatively, the two switching devices of the dual resonant forward converter are controlled to function as the linear regulator, thus reducing the required number of power devices.
