Title: Bicmos output buffer circuit with cmos data paths and bipolar current amplification
Inventor: OHANNES JAMES R
IPC: H03K19/088
Filed: 1992-12-04
Abstract: Attorney Docket No. NS18698 BICMOS OUTPUT BUFFER CIRCUIT WITH CMOS DATA         PATHS & BIPOLAR CURRENT AMPLIFICATION Abstract A BICMOS output buffer circuit incorporating CMOS transistors and bipolar transistors is coupled between high and low potential power rails (VCCI,GNDO) for delivering output signals of high and low potential levels at an output (VOUT). A bipolar output stage is formed by relatively large current conducting bipolar output pullup (Q24,Q22) and pulldown (Q44) transistors coupled to the output (VOUT) and provides relatively low output impedance.  Data signal paths coupled to the output stage are defined by CMOS transistors including CMOS input stages coupled to the input (VIN). Small current conducting CMOS transistors afford relatively high input impedance.  The bipolar output stage provides current amplification of data signals from the CMOS transistor defined data signal paths.  The P channel and N channel CMOS transistors of a pullup predriver input stage (Q15,Q14) are constructed with the P/N ratio of channel width dimensions skewed relative to the P/ ratio of channel width dimensions of respective P channel and N channel CMOS transistors of the pulldown predriver input stage (Q11,Q10) for skewing the input threshold voltage levels of the respective pullup and pulldown predriver input stages.  The skewed construction minimizes simultaneous conduction between the bipolar output pullup transistor (Q22) and pulldown transistor (Q24).  A pulldown driver stage (Q60,Q9A) coupled to a base node of the bipolar output pulldown transistor (Q44), includes a CMOS phase splitting pulldown driver transistor (Q60) and a fast CMOS Miller Killer (MK) transistor (Q9A) which functions as both DCMK and ACMK transistor.

Title: Method of and apparatus for di can surface treatment
Inventor: YOSHIMURA TAKAYUKI
IPC: B05B13/06
Filed: 1992-12-04
Abstract: PURPOSE: In A DI can surface treatment, it is intended to prevent adjacent cans in each of a plurality of partitioned rows from getting into contact with each other so as to eliminate defects such as irregular wash and thus improve quality of can bodies such as the adhesion of coatings to be applied.       CONSTITUTION: For treating the inner and outer surfaces, inverted DI cans are fed on a conveyer with partitioners in a plurality of rows such that they are spaced apart in each row, and treatment liquid is sprayed against the travelling cans from above and below the center of each row. It is sprayed from above in a uniform and a full-corn pattern greater in area tan the top surface of the can and from below also in a full-corn pattern or in a fan-shaped pattern narrow in the conveyer width direction and greater in length than the can open end diameter. It is further sprayed against the travelling cans from side nozzles on the opposite sides of and symmetric with respect to the center of each row. The side wall of cans is thus washed without contract of adjacent cans in the progress direction. Washing force is increased in the space between adjacent cans in the progress direction to permit uniform surface treatment of the inner and outer surfaces of cans without washing irregularities.

Abstract: FIBER OPTIC TELEPHONE LOOP NETWORK          Abstract of the Disclosure Novel fiber optic telephone loop networks are disclosed. In the networks, single mode fiber optics are used for feeder and distribution segments of the loop but multimode fiber optics are used for the drops. The use of the multimode fiber optics has permitted the use of less costly optoelectronic devices. Surface light emitting diodes are such economical but reliable parts. Fiber service terminals located near customer homes convert single mode operation to the multimode operation. The networks are relatively easy to install and upgrade and are very economically competitive with other known FTTC and FITH schemes.                             - i -

Abstract: A superconducting device comprises a substrate having a principal surface and a non-superconducting oxide layer having a similar crystal structure to that of the oxide superconductor, which has a projection at its center portion. A superconducting source region and a superconducting drain region formed of an .alpha.-axis oriented oxide superconductor thin film are positioned at the both sides of the projection of the non-superconducting oxide layer separated from each other and an extremely thin superconducting channel formed of a c-axis oriented oxide superconductor thin film is positioned on the projection of the non-superconducting oxide layer. The superconducting channel electrically connects the superconducting source region to the superconducting drain region, so that superconducting current can flow through the superconducting channel between the superconducting source region and the superconducting drain region. The superconducting device further includes a gate electrode through a gate insulator on the superconducting channel for controlling the superconducting current flowing through the superconducting channel. In the superconducting device the upper surfaces of the superconducting source region and the superconducting drain region have the same level as that of the superconducting channel.

Abstract: In order to control the velocity and spacing of a spaced feed of objects, there is a member rotatable about an axis and having at least one receptacle, the objects being fed into the apparatus in spaced succession so that they are captured in the receptacle and so that they acquire the circular motion of the member. The receptacle has means for releasing the objects so that they are projected with a predetermined velocity aid with a predetermined frequency. The phase relationship of a rotatable feeder and the rotatable member is controlled by generating a signal representative of the phase difference of the rotatable members, filtering the signal for maintaining loop stability and controlling the drive means of the rotatable member using the signal.

The pressure which prevails in the cassette reservoir interior space has a positive differential pressure (about 5000 Pa) with respect to the outside ambient to prevent any contamination thereof. The cassette reservoir is preferably made of a transparent and non-contaminating material such as a plastic. It is provided with a bar code tag (148) so that identification data attached to the wafer can be directly and automatically read by an appropriate reader. The cassette reservoir includes a drilled inner wall provided with holes that demarcates two regions within said container interior space: a first region in relationship with said gas injection valve means to form the reservoir properly said and a second region or receptacle adapted to receive a wafer holder (130). The cassette reservoir includes means for firmly and accurately maintaining the holder therein. The holder has a slot-shaped transfer opening (132) enclosing a single wafer (138) and is adapted to be inserted in and removed from and from the said receptacle through the said access opening at the beginning and at the end of the wafer processing step sequence. The holder is provided on its rear face with via-holes that are designed so that the gas flowing from the reservoir into the holder interior space, first through said holes, next through said via-holes, does not so easily penetrate in the holder interior space. The holder is preferably made of a transparent and non-contaminating material such as a plastic or pure SiO2 (quartz). The holder includes means for softly but firmly maintaining the wafer therein. <IMAGE>
