Title: Device for the discharge of intestinal gases
Inventor: GHEDINA DINO
IPC: A61F5/00
Filed: 1987-07-10
Granted: 1991-11-26
Abstract: ABSTRACT       For the discharge of intestinal gases at reduced pressure, use is made of a cylindrical hollow body (1) of flexible material, which is rounded at the insertion end (8) and which is made up of a front part (10) and a rear part (11). The side wall has gas intake openings (3) and connected to the second end region (7) of the hollow body (1) for the outlet of gas is a flexible thin tube (5) which reduces the outlet cross-section from the hollow body (1) as far as possible and which leads to the exterior, as the small outside diameter of the tube (5) permits the hollow body (1) to be positioned beyond the spincter muscle. The tube (5) preferably extends into the collecting space (2) of the hollow body (1) to close to the insertion end (8).

Title: Method for optical information recording
Inventor: OHNO EIJI
IPC: G11B7/006
Filed: 1987-10-30
Granted: 1991-06-25
Abstract: ABSTRACT A method for erasing and recording information on an optical recording member of the type wherein a new signal is overwritten on a previously recorded track by means of a single laser spot passing only once thereon.  The method comprises the steps of modulating a recording laser power to a recording power level (PW): maintaining the laser power at the recording power level (PW) for a time corresponding to data to be recorded: lowering the laser power to a cooling power level (PC) which is lower than the recording power level (PW); and maintaining the laser power level at the cooling power level (PC) for a predetermined period, to thereby record information.  By modulating the recording laser power at three power levels, the irradiation power becomes small immediately after the recording power level and thus the irradiated parts can be cooled quickly.  Therefore, a large amorphous area can be formed or a large difference between complex refractive indexes can be obtained, since the microcrystals are hardly included in the recording part, and the complex refractive index of the recording bit becomes small.  Therefore, a large reproduced signal is obtainable.

Title: Method and apparatus for encoding magnetic disk sector addresses
Inventor: WENG LIH-JYH
IPC: G11B20/12
Filed: 1988-07-06
Granted: 1993-11-16
Abstract: ABSTRACT OF THE DISCLOSURE      The invention encodes magnetic disk sector addresses using a large distance, "d", Reed-Solomon code to produce code words which vary by at least "d" symbols for any two different encoded addresses.  The result of the encoding is a set of redundancy symbols, which are usually associated with error correction.  These symbols are appended to the address symbols to produce address code words.  An address code word read from a disk can contain up to (d-1)/2 erros and still be identified as the correct sector address.  To protect the encoded sector address from synchronization errors the address code words are further encoded by adding them to a coset leader to produce header code words.  The header code words are then recorded in the address portions of the sectors. When a header code word is read from a sector, the coset leader is subtracted from the header code word to produce an address code word.  The address code word is then compared with the address code word for the specified address.  If there is a synchronization error, the comparison of the resulting address code word with the address code word for the specified address will result in more than (d-1)/2 symbols and the sector will not be treated as the specified address.

Abstract: SYSTEM FOR EXHAUSTING FUMES FROM RESIDENTIAL GARAGES            ABSTRACT OF THE DISCLOSURE            A system for venting exhaust fumes from vehicle engines being operated in enclosed spaces, such as in residential garages.   The system provides for conveying the gases from the vehicle exhaust pipe through an opening formed in the garage door or the like.   The equipment includes a door port mounted in the garage door opening and which defines a passage with a cylindrical interior surface extending through the door.   An exterior closure plate is pivotally mounted on the outside of the door port to swing between a closed vertical position covering the pas-sage and an upward, horizontal, open position.   The interior surface of the sleeve has an inwardly pro-jecting radial rib that defines an arcuate portion of an internal helical thread.   The exhaust fumes are conveyed from the exhaust pipe to the door passage by flexible tubing formed with helical corrugations that define an external helical thread.   One end of the tubing has a cylindrical outer surface extending beyond the helical corrugations and adapted to slide through the door port passage to engage and lift the closure plate.  When the tubing is then rotated about its axis, the external thread engages the internal helical portion to retain the tubing against axial movement that could cause disconnection.

Abstract: ABSTRACT OF THE DISCLOSURE           A control system and method for an apparatus for sealing packages wherein a web of flexible packaging material having a series of registration marks is formed into tubing and fed past. a sealing device for sealing the tubing to form packages.  As the tubing is fed past the sealing device,  a photoeye detects the registration marks.  A CPU, responsive to the photoeye, compares the location of registration marks relative to a window.  A counter, responsive to the CPU, sets a delay length of tubing to be fed past the sealing device in response to the relative location of the registration marks and the window.  The feeding of the tubing is stopped after the counter has been decremented to zero and the delay length of tubing has passed the sealing device.  An in registration delay length of tubing to be fed past the sealing device is set in response to detection by said photoeye of a registra-tion mark within the window.  An out of registration delay length to be fed past the sealing device is set in response to failure of the photoeye to detect a registration mark within the window.  The feeding of the tubing is stopped after the in registration delay length of tubing has passed the sealing device to allow sealing of the tubing at that point.  The feeding of the tubing is also stopped in response to failure by the photoeye to detect a registration mark dur-ing the period that the out of registration delay length is fed past the sealing device.   The in registration delay length has a magnitude which is a function of the relative location.
