Title: Veress needle assembly
Inventor: KULKASKI RICHARD
IPC: A61B19/00
Filed: 1992-04-23
Abstract: A Veress  needle  instrument consists of a housing serving as a handle, a hollow needle having one end mounted in the housing and a pointed other end, a tube slidably mounted within the needle, the tube having one end sealed off and a side wall hole proximate the sealed end, the other end of the tube passing through the hollow needle and into the length of a passageway of a spring biased bobbin mounted in the housing, with the other end being secured in the passageway.  The passageway of the bobbin opens into a porthole thereof for receiving a fluid coupling through a hole in the top end of the housing, thereby permitting fluid to be passed directly between the tube and the fluid coupling.  The bobbin is normally biased toward the bottom end of the housing, for causing the one end of the tube to extend away from a pointed end of the needle with the side hole of the tube unobstructed.  When a force directed against the end of the tube causes it to retract into the needle, the bobbin moves toward the top end of the housing, causing a colored portion of the bobbin to protrude out of the hole in the top end of the housing, for providing a visual indication that the one end of the tube has retracted into the needle.

Filed: 1992-04-24
Abstract: 1 A synchronous motor includes a unitary rotor, a first stator (10), a second stator (14) and phase-changing switches (20). The unitary rotor has a first rotor portion formed by a first permanent magnet (2) and a second rotor portion formed by a second permanent magnet (4) and an induction type rotor (5) and these first and second rotor portions are mounted on a common rotary axle with a predetermined space provided therebetween. The first stator (10) faces the first rotor portion for producing a first rotating magnetic field. The second stator (14) faces the second rotor portion for producing a second rotating magnetic field and is disposed such that, at the starting operation, the attracting action or the repelling action produced between the first rotating magnetic field and the first permanent magnet is canceled by the repelling action or the attracting action produced between the second rotating magnetic field and the permanent magnetic field. The phase-changing switches are associated with either one of the first stator or the second stator and set a phase difference of 0 degree or 180 degrees between the first rotating magnetic field and the second rotating magnetic field. Due to the cancellation action, any starting interference which may otherwise be caused by the permanent magnets is made negligible.

Title: Method of detecting information from magnetooptical recording medium, method of detecting information from optical recording medium, and optical recording medium
Inventor: TSUZUKIYAMA KOJI
IPC: G11C11/56
Filed: 1992-07-07
Abstract: ABSTRACT    The information detecting method of the invention comprises irradiating a recording medium with a linearly polarized light, causing the reflected light from the medium to be transmitted by a .lambda./4 plate which is configured at an azimuth of approx. 45°, then causing the transmitted light to enter into a polarization beam splitter which is configured at an azimuth of approx. 90° to split the light into a P component and a S component, detecting the P component and the S component individually by a photosensitive detector, and differentially amplifying signals of the P component and the S component by a differential amplifier to detect the reproduced signals based on Kerr ellipticity.  According to the information detection method, the reproduced signals can be detected with a high S/N ratio and the optical detection system can be simplified.  Further, the information detection method based on the Kerr ellipticity can be used in combination with an information detection method based on Kerr rotation angle or a reflectance, and thereby detection of multi-level signals becomes possible.  Hence, recording of information with high density can be attained.  According to the invention, moreover, an optical recording medium capable of being recorded with multi level signals and suitably used for the above-mentioned information detection methods can be provided.

Title: Transfer pad cover
Inventor: ERYOU N DENNIS
IPC: E04B1/343
Filed: 1992-09-24
Abstract: Abstract of the Disclosure A transfer pad cover includes a frame structure covered by a water-proof sheet material.  The frame structure is supported by bar joists that are mounted for movement along tracks.  The entire structure is moved by hand or motor or by a truck from which a liquid transfer will be made to a position adjacent the transfer pad during the transfer operation.  When the material and frame structure are sufficiently weighted down so that it is unsafe to move the cover, the joists will rest on a ground surface, preventing movement of the cover.  In an alternate embodiment, the rails are sloped and the truck pushes the cover off of the pad.  When the truck leaves the pad, the slope of the rails causes the cover to automatically return to * protect the pad under the influence of gravity.
