Abstract: In an image processing apparatus, a matrix for an arbitrary pixel (to be an observed pixel) on the original image is set up so that the density of the observed pixel and that of a target pixel which is located in the direction along which shadows are formed are compared to determine a maximum value of density of the two. If the density of the observed pixel is greater than that of the target pixel or pixels, the density of the target pixel is converted into a predetermined level of density, whereas if the density of the observed pixel is less than that of the target pixel, no conversion of density is made. This procedure is repeatedly performed for the entire image information to thereby create shadows having a designated length and complete a shadowing image. Then, the shadowing image is combined with the original image, whereby a shadowed image is complete.

Abstract: A full cutting element including a substantially cylindrical backing and cutter mounted thereon is cut generally along the length thereof to produce a pair of semicylindrical partial cutting elements. In the case of an unused cutting element, each partial cutting element is mounted on a different semicylindrical tungsten carbide base to produce a substantially cylindrical unit which is mounted on a bit using a low temperature braze. In the case of a used full cutting element, the cutting element is cut to separate the worn portion from the remainder of the bit and only the unused portion is used to form a cylindrical unit with a corresponding semicylindrical tungsten carbide base. In another aspect, a partial cutting element is received in a pocket formed on a bit body. The pocket includes a pair of opposed side surfaces which substantially flushly abut the curved surfaces of the backing on the partial cutter.

Abstract: A system (100) controls the concentration of toner in developer in an  electrophotographic printer. Toner is applied on a test patch (SD) on a charge-retentive surface  in a manner consistent with a desired toner density on a test patch, and the actual toner density  on the test patch (SD) is measured. The charge applied to the charge-retentive surface is then  adjusted in response to the measured actual toner density to obtain the desired toner density  on a subsequent test patch (SD opt ). The change in charge applied to the charge-retentive  surface is used to detect a shortage of toner in the developer and feed means (17) is controlled  to add toner to the developer.

Abstract: In an active pixel imaging system and method to generate an differential output signal consisting of the differences in a viewed image between adjacent detected frames a buffered electrical charge storage capacity (110) of the active pixel sensor (35) is utilized to provide a system with reduced complexity and hardware requirements. In the imaging system, when a particular active pixel sensor is activated it generates a voltage signal (at 50) corresponding to a previous frame's detected light intensity before the pixel is reset to generate a voltage signal (at 50) corresponding to a present frame's detected light intensity. A differential output circuit (18) is used to generate a differential output signal based on these two generated voltage signals.

Abstract: L'invention porte sur des analogues du motif CAAX de la protéine Ras modifiés in vivo par farnésylation. Lesdits analogues, qui inhibent la farnésylation de la Ras, diffèrent par ailleurs de ceux précédemment décrits comme inhibiteurs de la Ras farnésyle transférase en ce qu'ils ne présentent pas de fraction thiol. Cette absence de thiol offre des avantages uniques en matière d'amélioration du comportement pharmacocinétique chez les animaux, de prévention des réactions chimiques liées aux thiols telles que la rapidité de l'auto-oxydation, la formation de bisulfures avec les thiols endogènes et une toxicité systémique réduite. L'invention porte également sur des compositions chimiothérapeutiques contenant les susdits inhibiteurs et sur leur procédé d'obtention.

Abstract: A method (40) of fabricating self-aligned static induction transistors (10) is disclosed. The method (40) comprises fabricating (41) an silicon substrate (11) having an active area 14a. A guard ring (15) is formed (43) around the active area. Source and gate regions are formed, and a self-aligned relatively deep trench in accordance with the present invention is formed over the gate regions. This is achieved by forming (45) an oxide layer, and forming (46) a polysilicon layer on the oxide layer. A second oxide layer is formed (47) on the polysilicon layer which is then masked (48) by a self-aligning mask. Trenches 21 are etched (49) into the substrate using the self-aligning mask and gate regions are formed (50) at the bottom of the trenches. The transistors (10) are then processed to completion by forming gate, source and drain regions. This portion of the method comprises the steps of forming (51) maskless self-aligned gate metallization, forming (54) maskless self-aligned contacts to the gate metallization and filling the trench, forming (55) source metallization, and forming (58) a drain contact on the substrate. The present method (40) employs a single minimum geometry trench mask. The key features of the transistors (10) are defined by the trench mask and related processing parameters. Because of the self-alignment achieved by the present invention, the number of channels per unit area is higher, which results in higher transconductance. In addition, some parasitic capacitance is eliminated by the present invention, resulting in faster operational speed. The variable sidewall trench oxide thickness allows fabrication of static induction transistors (10) with higher or lower breakdown voltages according to the thickness that is chosen, and for a more graded gate junction.

Abstract: A light pickup 4 is adapted to receive reflected light from a disc 1 and to input a signal into a determination means 12 while moving in the radial direction of the disc 1. The determination means 12 not only determines the current position of the light pickup but also calculates the time required for the light pickup 4 to move until reaching the signal-recording inner circular end of the disc, on the basis of the signal from the light pickup. The determination means 12 determines that no disc is set when there is no reflected light from the disc. The determination means 12 determines the size of the diameter of the disc 1 on the basis of the current position of the light pickup 4. The disc player has a structure in which it is not necessary to provide a switch for detecting the signal-recording inner circular end of the disc, a sensor for detecting the size of the diameter of the disc and a sensor for detecting whether or not the disc is set.

Abstract: A voltage regulator with load pole stabilization is disclosed. The voltage regulator consists of an error amplifier, an integrator which includes a switched capacitor, a pass transistor, and a feed back circuit. In one embodiment, the integrator circuit includes an amplifier, a capacitor, and a switched capacitor which is driven by a voltage controlled oscillator. The voltage controlled oscillator changes its frequency of oscillation proportional to the output current. In another embodiment, the switched capacitor is driven by a current controlled oscillator whose frequency of oscillation is also proportional to the output current of the voltage regulator. When the output current demand is large, the controlled oscillators increase the frequency which decreases the effective resistance of the switched capacitor thereby changing the frequency of the zero to respond to the change in the load pole. Conversely, the effective resistance is increased as the current demand is decreased, also to respond to the decrease in load pole. Consequently, the disclosed voltage regulator has high stability without consuming excess power.
