Abstract: A large capacity data storing disk includes a volume table of contents (VTOC) which identifies allocated ones of data storage tracks and identification of the data contents therein, indications of unallocated data storage track and an indication of which of the data storage tracks on the large capacity disk surface are unformatted. The indica­tions may also include indications of unallocated "erased" tracks that do not contain data residuals from previous recordings. Those unallocated tracks having such erased condition in a count key data record format (CKD) require a home address record on each of the formatted tracks. The home address record may include indications of rotational position of defects to be skipped over during the recording and readback operations. A specific embodiment of the invention using a magnetooptic record medium is described.

Abstract: A condition monitoring system for monitoring the condition of a two-position switch (SW), e.g. in a car or other vehicle, is arranged to provide selective drive signals to the switch and receive an input signal from the switch, the system responding to the received input signal (IN) to select which drive signal is applied to the switch so that little or no current is drawn from the system by the switch in either of its positions (A or B). Thus in the position shown, a low drive signal is applied to switch terminal (A) and a high drive signal is applied to terminal (B) and little or no current passes through the switch to its common terminal (C): however if the switch is changed to its other position a current passes through the switch from terminal (B) and a high input signal is applied at IN; in response to this the system charges the output drives to apply a high signal on terminal (A) and a low signal on terminal (B). In this manner little or no current is drawn by the switch in either of its positions, but at changeover a high input signal will flow until the monitoring system responds.

IPC: H01L21/301
Filed: 1989-10-04
Abstract: The present invention covers a semiconductor wafer for semi-custom use in which there are no scribe lines in at least one direction. Electrically isolated cells are provided throughout the wafer. The scribe lines can thus be arbitrarily placed according to an individual customer's instructions, with the isolated cells near the scribe line being covered with metalization to form a bonding pad. Preferably, scribe lines are provided in one direction, either horizontal or vertical. This allows fixed bonding pads to be placed near these scribe lines and allows special components, such as power transistors and ESD protection systems to be placed near the fixed bonding pads. This provides better silicon efficiency than the embodiment with no fixed scribe lines by simplifying the routing. The components which need to be near the bonding pads are placed there, rather than being located randomly throughout the wafer. The customer can then specify a length of a cell which has a fixed height.

The amount of rotation is determined by the setting of the rotating prism (14). The imaging lens (16) provides the required magnification or demagnification. The translating mirror (18) is shifted to provide the necessary translation. The pulsed image passes through the optical loop many times to perform the transformation. An optical Iterated Function System is implemented by connecting a plurality of the optical loops in parallel, together with shutters or beamsplitters for guiding the pulsed image to different loops according to the probabilities assigned by the Iterated Function System.

Abstract: A video signal is recorded in oblique tracks on a magnetic tape. The tracks are successively scanned by rotary heads, and a reproduced radio frequency signal is obtained. The level of the signal as reproduced exhibits a nonlinearity as a function of deviations of the rotary heads from the successively scanned oblique tracks. In accordance with the invention, the running speed of the tape is controlled on the basis of the detected changes in signal level, and the gain of the reproduced radio frequency signal is controlled in such a way as to compensate for the nonlinearity of the reproduced signal.

Abstract: A method comprising passing through a zeolite catalyst, a gaseous stream containing nitrogen oxides, ammonia and oxygen to selectively catalyze the reduction of nitrogen oxides and, if excess or unreacted ammonia is present, to oxidize the excess of unreacted ammonia with oxygen to hydrogen and water. The method includes the use of a zeolite catalyst composition which comprises a metal (e.g., iron or copper) promoted zeolite, the zeolite being characterized by having a silica to alumina ratio of at least about 10 and a pore structure which is interconnected in all three crystallographic dimensions by pores having an average kinetic pore diameter of at least about 7 Angstroms. Promoted zeolites of the above type have demonstrated high tolerance for sulfur poisoning, good activity for the selective catalytic reduction of nitrogen oxides with ammonia, good activity for the oxidation of ammonia with oxygen, and the retention of such good activities even under high temperature operations, e.g., 400°C or higher, and hydrothermal conditions.

     The valve assembly may comprise a generally cylin­drical body (2) having a transverse wall (12) between the inlet and the outlet and provided with two openings (8, 10), one controlled by a pressure responsive main valve member (9) movable axially towards and away from the opening (8) in dependence on the pressure and the other controlled by an auxiliary valve member (11) manually rotatable about the axis of the body to open and close the opening (10). 
     In use, the main valve is arranged to cut off the flow of gas to the utilising means before the container is exhausted to warn the user that the container is nearly empty and needs replenishing. The flow of gas can be re­instated, while a replacement container is being organ­ised, by manual operation of the auxiliary valve means.
