Abstract: An apparatus for automatically counting stacked sheet-like materials having sheet-to-sheet brightness gradients alternating between positive and negative while simultaneously eliminating problems encountered when the sheet edge reflectance charac­teristics have combined lambertian and specular reflective natures. Rectification of a pitch matched sensor arrays data output combined with a selective disposition of the sensor and illumination optical components relative to the sheet edges to be counted based upon the maximum acceptance angle of the optical system yields the improved count data necessary to achieve accurate counting.

Abstract: A vehicle speed control system is provided to maintain the vehicle speed at a target value. The control system includes a target vehicle speed determining section, a section for calculating a driving torque necessary to drive the vehicle at the target vehicle speed, a section for calculating a target engine rotational speed and an engine load torque and a section for calculating a control amount for controlling an opening of the throttle valve of the engine. The driving torque calculating section and the control amount calculating section are designed based on linear control theory on physical models describing the behavior of the vehicle and the engine, respectively, thereby improving the responsiveness of the control system compared to conventional PID control. The design of the control system is characterized by separate sections which reduces designing labor and which facilitate standardization of every section.

Abstract: A first hydrogen sulphide containing waste gas stream from an oil refinery is combusted in a first combustion chamber 16 using pure oxygen to support combustion. The combustion products are cooled in heat exchanger 20, and a part of the combustion products are recycled to the chamber 16 to moderate the temperature therein. The remainder of the combustion products are mixed with a second hydrogen sulphide containing waste gas stream of different composition from the first stream. A proportion of the hydrogen sulphide content of the mixed stream is combusted in combustion chamber 28 again using pure oxygen to support the combustion. The resulting sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapour.

Abstract: An improved differential input amplifier stage used as the input stage in digital differential line receivers or operational amplifiers. The differential input amplifier stage has a pair of input transistors (22, 23) forming a differential pair with a common node (N4) and two complementary output nodes (N3,N3'); a current mirror, coupled to the two complementary output nodes and responsive to a first one of the two complementary output nodes and a single-ended output signal on the second one of the two complementary output nodes; and a current source transistor coupled to the common node (N4) and responsive to the first one (N3') of the two complementary output nodes. The current source transistor maintains the voltage on the first one of the two complementary output nodes substantially constant, thereby improving common mode and power supply noise immunity and providing faster differential response by the differential input amplifier stage.

Abstract: A data recording disk file with a voice coil motor (VCM) actuator (40) and a digital servo control system for positioning the read/write heads (30, 32, 34, 36) to selected concentric data tracks includes means for calculating the factor relating acceleration of the heads (30, 32, 34, 36) to VCM input current. This permits each disk file to compensate for any variation in the nominal VCM physical parameters, thus enabling VCMs to be manufactured to less demanding tolerances. The disk file also calculates a unique acceleration factor for each head position during movement of the heads (30, 32, 34, 36) from one track to another, thereby improving the arrival time of the heads (30, 32, 34, 36) to the target track. During an initialization procedure, the disk file performs a track seek, during which VCM current and head velocity information are acquired and used by the microprocessor (80) in the digital servo control system to calculate a value representing an average actual acceleration factor unique to that disk file. This value, together with predetermined constants representing the characteristic relationship of acceleration factor to head position in a disk file with a nominal VCM, are used by the microprocessor (80) to calculate the actual acceleration factor for each head position during a track seek.

Abstract: Non-continuous reflective holograms or diffraction gratings are provided in various forms for authenticating documents and things, and for decorative and product packaging applications. In one specific authentication application, such a hologram or diffraction grating is firmly attached to a surface that contains visual information desired to be protected from alteration. Examples of such information include written personal data and photograph on a passport, driver's license, identity card and the like. The reflective discontinuous hologram is formed in a pattern that both permits viewing the protected information through it and the viewing of an authenticating image or other light pattern reconstructed from it in reflection. In another specific authentication application, a non-­transparent structure of two side-by-side non-continuous holograms or diffraction patterns, each reconstructing a separate image or other light pattern, increases the difficulty of counterfeiting the structure.

Abstract: A sheet piece intended to form, for example, an encasing wall (53) of a portable container, consisting of a plurality of material layers (54, 55, 56) mainly of paper. The material layers are provided with a large number of localized impres­sions distributed uniformly over the surface of the layers with spaces in between the impressions. The impressions extend from the principle plane (58, 59, 60) of each layer. The impressions (57, 62) in adjacent layers are, with respect to their posi­tions, displaced relative to one another as viewed in the nor­mal direction of their principle planes (58, 59, 60). This involves that the impressions in one layer are located directly in front of the spaces in adjacent layers. Each of the layers is joined with its adjacent layers by means of an adhesive, whereby a large number of closed cells (64) are created, so that at most two layers are directly joined together with each other.
