Abstract: Disclosed herein is an electrostatic spray-painting method and an electrostatic spray-painting ap-paratus.  This method basically comprises the steps of supplying a predetermined amount of water-based paint to an intermediate reservoir from a grounded water-based paint feed source through a feed line having an electrically-insulated portion formed in at least a part thereof; washing the electrically-insulated por-tion with deionized water having specific electric con-ductivity lower than given specific electric con-ductivity; removing the deionized water remaining in the electrically-insulated portion by using dry air after completion of the washing step so as to electri-cally insulate the water-based paint feed source from the intermediate reservoir; and supplying the water-based paint to a spray gun from the intermediate reser-voir under the condition of the water-based paint feed source and the intermediate reservoir being electrical-ly insulated from each other, thereby carrying out an electrostatic spray coating process.  The above appara-tus basically comprises a color changeover valve me-chanism, a first directional control valve, a block line, a second directional control valve, an intermedi-ate reservoir, a waste-liquid tank, a spray gun, and a high-voltage applying device.

Patent CA-2079754-C (CA)
Inventor: SLICKER JAMES MELVIN
IPC: G05D17/02
Filed: 1992-10-02
Granted: 1998-11-03
Abstract: An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor and a transmission input speed sensor and develops a clutch actuation signal controlling a clutch actuator between from disengaged to fully engaged. The clutch actuator at least partially engages the friction clutch in a manner to cause the measured transmission input speed to asymptotically approach a reference speed employing an approximate inverse model of this oscillatory response.          In a launch mode, corresponding to normal start of the vehicle, the reference speed is the measured engine speed.          In a creep mode, corresponding to slow speed creeping of the vehicle, the reference speed is a creep speed reference based on the throttle setting and the engine speed. The two modes are selected based upon the throttle setting. The automatic clutch controller preferably includes an integral error function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading. The automatic clutch controller includes a prefilter and a compensator constructed to reduce the need for detailed particularization for individual vehicles or vehicle models.

Title: Skate boot with moulded plastic overlay
Inventor: HOSHIZAKI T BLAINE
IPC: A43B5/16
Filed: 1992-12-08
Granted: 1999-04-20
Abstract: A skate boot is described, having a plastic overlay sewn or otherwise secured to the boot of the skate, wrapping around the heel of the boot from the medial to the lateral side of the ankle.  The overlay increases the rigidity of the rear of the skate, to restrict pronation and supination, while adding impact resistance.  Preferably, in order to permit dorsal and plantar flexion, the plastic overlay has several cut-out areas which allow for a controlled amount of flexion about a lateral axis, namely a heel flex cut-out area and side flex cut-out areas on either side in the instep area.          Flexible inserts are preferably installed in the cut-out areas, to maintain extra impact protection while permitting flexion.

Granted: 2000-11-07
Abstract: A device is disclosed for stowing away a thick cable composed of several leads, in particular the supply cable of a central energy supply installation for the supply system on board of aircrafts, for example. The device has a rotary winding drum, around which several turns of the cable can be wound, connected in turn by a compensating cable preferably to a fixed connection. The leads of the compensating cable, that lie free at least in sections, extend in the axial direction of the winding drum, so that the compensating cable is more strongly twisted when the connecting cable unwinds from the winding drum and less strongly twisted when the connecting cable is wound on the winding drum. The winding drum itself has a hollow cylindrical bearing body for winding up a single layer of cable, within which extends the compensating cable. Preferably, the compensating cable or some of its leads axe held or fixed in an approximately central position within the bearing body. In order to obtain a friction-reducing support of the cable, rotatably mounted sliding elements, such as ball bearing shafts that cooperate with each other, extend parallel to the axis of the cable winding roller, spaced apart therefrom.

The height of the outermost projection varies from a minimum height near the middle of the deck, to a minimum height near the end of the deck. The mold receptor receives a shell (22) which has a finish side and a non-finish side. The shell is placed in the mold receptor leaving a void between the non-finish side of the sheel and the deck insert of the receptor. The insert is attached to the mold receptor to reduce the cross-sectional area of a portion of the space between the shell deck and mold receptor. A male mold (54) engages the finish side of the shell, sealably retaining the shell to the mold receptor. A polymeric material is introduced into the void between the receptor and the shell. The polymeric material fills the void and coats the shell. The molded bathtub is then removed from the mold receptor after the male mold has been remove. The non-finish side is coated with a polymeric material and has an area of reduced thickness in the polymeric material coating the deck.

Title: A dielectric isolated high voltage semiconductor device
Inventor: SAKURAI NAOKI
IPC: H01L29/78
Filed: 1993-10-29
Granted: 1999-01-05
Abstract: A new semiconductor integrated circuit uses a dielectric separation substrate for realizing a high withstand voltage and high integration.  The arrangement extends a depletion layer of a main junction beyond an insulating layer sandwiched between a support and semiconductor islands by applying a bias voltage to the support and the islands.  This main junction is a pn junction to which a reverse bias voltage for securing the withstand voltage of the semiconductor element is applied. The impurity density and the thickness of the region between the bottom of the semiconductor island and the circuit element regions is set so that this region is fully depleted by a lower voltage than that at which avalanche breakdown would occur.  For this purpose the distance between the bottom part of the island and the main junction is made less than 1/14V µm when the withstand voltage of the circuit element is V volts.
