Patent EP-0403267-A2 (EP)
Inventor: KUDOH HITOSHI
IPC: H01L29/78
Filed: 1990-06-13
Abstract: The semiconductor device of the invention possesses a combined structure of several transistors. Hitherto, sharing of gate in the circuit composition or sharing of drain of preceding transistor and source of succeeding transistor has been known, but the invention includes plural transistors in which the transistors themselves share a channel region. In other words, the semiconduc­tor device of the invention is compounded in a form of sharing the gate and source by plural transistors, and possesses three or more sources and drains. 
     In such constitution, not only the drain current is determined depending on the potential difference of the pair of source and drain, but also the individual drain current increases or decreases depending on the voltage application condition (potential difference) of all source and drain terminals. In the invention, having three or more sources and drains, the drain cur­rent increases or decreases depending on the magnitude of the voltage applied to them. Therefore, assuming one of the plurality of source and drain terminals to be a control terminal (disturbance terminal) of the transistor having other pair of source and drain, by applying a proper voltage to the source and drain termi­nals, instability or drift of the transistor operation may be intentionally produced.

Procedures are specified by a procedural language which includes current panel operations being permitted as a panel commands in the procedural language. The panel may call these procedures and the procedures may thus include panel actions executed by the panel executor upon being called. The procedure monitors the state of the current panel which may comprise monitoring multiple fields and may effect changes thereto automatically and as a function of the monitoring, as well as direct commitment of data in the panel. Provision is further made for looping logic in the procedures whereby batch panels are effected without the need for user interaction.

Abstract: A method and apparatus are provided for processing digital video signals for transmission in a compressed form. A set of pixel data is compressed without motion compensation to provide a first compressed video signal. The pixel data is compressed using motion compensation to provide a second compressed video signal. The data in the first and second compressed video signals is quantified. A comparison is made to determine which of the signals contains the least data. Successive sets of pixel data are sequentially compressed and quantified and the compressed video signal having the least data for each particular set is selected. The selected signals are encoded to identify them as motion compensated or non-motion compensated signals, and combined to provide a compressed video signal data stream for transmission. Apparatus for receiving and decoding the signals is also disclosed.

IPC: G01B7/00

Abstract: This detection device comprises a coil section (1A-2B) and a rod section (6) which is capable of linear displacement relative to the coil section. The rod section has a magnetic substance portion (6a) changing reluctance of a magnetic circuit passing through the coil section in accordance with the linear displacement and a conductive substance portion provided in part of the rod section where the reluctance is caused to increase relatively in such a manner that an eddy current path will be formed relative to flux. By this arrangement, in places where reluctance increases due to absence of the magnetic substance, reluctance is caused to further increase by the eddy current loss produced by presence of the conductive substance portion whereby the secondary side induced voltage level is further attenuated and the accuracy of detection can be improved. The rod section may be so constructed as to produce only the reluctance change due to the conductive substance portion. This detection device is applicable to detection of a piston rod position of a fluid powered cylinder.

Abstract: The Si units of the novel polycarbosilanes are linked by phenyl-substituted methylene bridges or by partially or fully fluorinated hydrocarbon bridges. The novel polycarbosilanes are obtained by a Grignard polycondensation reaction. Any phenyl substituents on the silicon atoms in the novel polycarbosilanes may optionally also be replaced by halogen atoms by subsequent halogenation reactions, so that it is also possible to obtain polycarbosilanes which are both fluorinated in the hydrocarbon bridges and halogenated, in particular fluorinated, on the silicon atoms.

IPC: C08J5/24
Filed: 1991-02-07
Abstract: A process is described for preparing thermoset composite articles under relatively mild conditions. The process includes exposing a laminate comprising a partially-cured thermosettable resin and a fibrous substrate to an elevated temperature which increases over time, the elevated temperature being below the glass transition temperature of the resin but sufficient to promote further curing and increase the glass transition temperature thereof to the ultimate glass transition temperature of the resin. The temperature of exposure is generally increased at a rate which maintains the temperature within 20°C below the glass transition temperature of the thermosettable resin, so that cure of the resin proceeds in the glassy state. The pressure during the process is generally maintained below 3.4 atmosphere and is preferably atmospheric pressure. The process enables the production of thermoset composite articles suitable for high-performance applications without lengthy autoclave treatments.

Abstract: A solid-state imaging device includes a plurality of light receiving elements, transfer gates for controlling reading-out of signal charges detected in the light receiving elements, a charge coupled device for transferring the signal charges in the light receiving elements successively by the ON operation of the transfer gates, and a charge input means provided at the initial stage of the charge coupled device. This charge input means is constituted by a charge input source, and a first and a second electrodes for controlling the quantity of input charges from the charge input source. The first electrode of the charge input means is arranged in contact with the charge input source. The second electrode is arranged in contact with the first electrode and connected with the light receiving element via the transfer gate or another charge coupled device. In this structure, the second electrode serves as an electrode for controlling the quantity of input charges by applying a dc voltage thereto at the charge input mode while it serves as a first stage transfer electrode by applying a clock pulse thereto at the imaging mode. Thus, operations at both modes can be performed without changing the array pitch of the light receiving elements at the charge input part.
