Abstract: The control system for an automatic transmission shifts the main transmission simultaneously with the auxiliary transmission at the time of a particular shift. At this time, a target gear ratio progress value of the auxiliary transmission is set for a gear ratio progress value indicative of a shift progress state of the main transmission. The main transmission is arranged so as to finish the shift control within a given target period of time, and the auxiliary transmission is arranged to implement the shift control by the feedback control so as to follow the target gear ratio progress value. The shift control of the auxiliary transmission is corrected by the learning control on the basis of a deviation between the target gear ratio progress value and the actual gear ratio progress value.

Abstract: A method and device for use in measurement and compensation of non-linear bitshift in non-linear communication media such as magnetic and optical recording devices. The method and device are based on special bit patterns constructed to eliminate at least one harmonic of the fundamental frequency of the data pattern if all bits are communicated without any non-linear bitshift. The presence of non-linear bitshift is manifested by the appearance of the harmonic. By measuring the magnitude of the harmonic, the amount of non-linear bitshift is determined, and compensation adjustment is then used to offset its effect on the data detection scheme.

Abstract: It is advantageous to oscillate a beam on objects when a high power CO₂ laser beam or a high power YAG laser beam is used to weld or anneal the objects. In order to let a laser beam scan, a device for reciprocating a lens or a device for rotating two mirrors synchronously has been proposed. These devices suffer from the difficulty of cooling. Prior devices are not applicable to a high power laser. A parallel laser beam (5) is first reflected by a parabolic mirror (2). Then a mirror (3) which can be swayed reciprocally by a galvanometer reflects the beam toward the objects (13). A water inlet (11) and an outlet are mounted on a rear surface of the swaying mirror (3). The cooling water is carried by coiled tubes. Excellent heat diffusion prevents the galvanometer from malfunction.

Waste fuel is introduced into the fluidized bed within one vessel (30) where it is mixed with bed make-up material that is controlled to provide an ideal environment for the generation of pyrolytic gases. The fluidized bed material is pneumatically and gravitationally conveyed downwardly, and injected into a fluidized bed within the second vessel (32) where the involatile organic material undergoes combustion in an oxidizing atmosphere. The bed material in the second vessel is pneumatically conveyed upwardly and divided into two portions, one of which is recycled back to the first vessel. The other portion of the bed material in the second vessel is circulated to a fluidized bed within the third vessel (34) where heat is recovered. The bed material in the heat recovery vessel is gravitationally conveyed back to the second vessel to regulate the temperature in the latter vessel.

Abstract: SOI (silicon-on-insulator) technology has been touted as a promising approach for fabricating an advanced integrated circuits because of its advantage over bulk silicon circuits such as faster speed and improve radiation tolerance. One drawback to SOI is that parasitic bipolar induced latch-up/breakdown voltage levels severely limits the maximum supply voltage at which SOI circuits and devices can operate. When the parasitic device turns on, the SOI transistor cannot be switched off by changing the gate bias. What is described is a method whereby the operating voltage in which this effect occurs is significantly increased thus allowing circuit operation at reasonable power supply voltages. The method is to implant a neutral impurity ion such as krypton, xenon or germanium into the device (10) to form ion scattering centers. The size of the impurity atom must be much larger than the size of the silicon atom. The size difference generating a scattering center.
