Patent EP-0372072-A1 (EP)
Inventor: SCHUMACHER ROBERT W
IPC: H01J17/06
Filed: 1989-05-08
Abstract: Un commutateur au plasma utilise une cathode froide qui émet des électrons secondaires pour entretenir un plasma dans le commutateur. Cette cathode est caractérisée par une série de perturbations qui augmentent la superficie de la cathode effectivement exposée au plasma et qui augmentent la longueur de trajet efficace moyen des électrons secondaires émis par la cathode et la probabilité de collisions ionisantes de ces électrons avec des molécules de gaz contenues dans le commutateur. La surface interne de la cathode est pourvue d'un revêtement en chrome ou en un mélange de chrome. Le chrome associe un taux élevé d'émission d'électrons secondaires à une faible vaporisation et d'autres propriétés avantageuses pour l'exploitation du commutateur au plasma. L'invention porte sur plusieurs types de profils de perturbation chromés.

Abstract: On peut former des copolymères blocs à partir de polymères hétérocycliques tels que le polybenzoxazole et de polymères thermoplastiques tels que la polyamide ou le poly(cétone éther aromatique). Les compositions de copolymères blocs sont thermoplastiques et ne présentent aucune séparation de phase notable, même à des températures approchant leur température de transition vitreuse. On peut donner à ces compositions de copolymères blocs des formes de fibres, de feuilles ou de stratifiés ou d'objets façonnés par compression. Les polymères polybenzoxazoles, polybenzothiazoles et polybenzimidazoles terminés par un anneau aromatique actif ou des groupes acylatiques se prêtent particulièrement bien à la préparation de ces copolymères blocs.

Abstract: In accordance with the teachings of this invention, a novel auto-zero comparator (700) is provided in which the on resistance of MOS switches (117,118) serving as transfer gates used in the auto-zero mode to connect the output lead (113,114) to the input lead (111,112) is minimized without the need to increase the width to length ratio of the MOS switches (117,118). In accordance with the teachings of this invention, the on resistance of the transfer gates (M4A,M4B) is reduced by reducing the threshold voltage of the transfer gates (M4A,M4B), which in turn is accomplished by making the bulk to source voltage of the transfer gates (M4A,M4B) equal to zero. This is accomplished by utilizing a replica bias circuit (70L) which, during the auto-zero mode, replicates the voltage on the source of the transfer gates and applies this replica bias voltage to the bulk of the transfer gates.

Abstract: An automatic programming method of preparing NC data efficiently and automatically from a part program even when undefined symbols are included in the part program. The processor in an automatic programming apparatus automatically prepares NC data by successively decoding and executing the statement of the part program that is read from the RAM. When it is determined that an undefined symbol is contained in the decoded statement (S4), the processor displays the undefined symbol on the screen and requests to define the symbol (S6). When a definition sentence of the undefined symbol and an input instruction for permitting the input of the definition sentence are manually input (S7), the definition sentence is automatically inserted just before the statement that includes the undefined symbol, and the statement of a part program that follows the definition sentence is executed (S7,S8).

Abstract: The present invention enables safety cooking for any kind of menu through simple manipulation of keys. 
     As the temperature of the cooking pan (31) is measured, by the temperature detecting means (25), the moisture detecting means (26) decides whether the material to be cooked is to be boiled, sauteed or fried. In the case of the material to be boiled, the scorching preventing means (27) works to prevent scorching of the material. In the case of the material to be sauteed or fried, the overheating preventing means (28) prevents overheating of the material. For this end, the temperature detecting means (25), detecting how the temperature of the cooking pan increases, controls the heating means (10) via the heating controlling means (24). 
     Accordingly, the material can be cooked safe irrespective of the cooking fashion if only the force adjusting knob (4) and ignition/extinction button (6) are manipulated.

Abstract: Measurement apparatus and procedure for use with lithographic equipment is provided for the construction of electronic and other devices wherein a photoresist is deposited as a layer upon a substrate (20). A Nomarski differential interference contrast microscope (62) in conjunction with a scanned image detector is employed to examine verification marks (28, 30) produced by projection of an overlay, such as the mask or reticle (94), upon the photoresist layer. The projection results in a production of verification marks (28, 30) in the form of a latent image which, while invisible with conventional viewing means, can be viewed by phase-contrast imaging employing differential phase shift. Various characteristics of the resultant image are employed to align secondary verification marks (30) with primary verification marks (28) previously provided on the substrate (20), and to allow for a checking of line width, dosage, focusing, temperature control, and global alignment. Observation of the photoresist is accomplished with radiation at lower frequency than the exposure radiation, the latter being significantly absorbed, by the photoresist, the photoresist being transparent to the observation radiation to permit reflection from top and bottom surfaces of the photoresist.
