Title: Solid-state image pick-up device with uniform distribution of dopant therein and production method therefor
Inventor: KATO YASABURO
IPC: H01L31/18
Filed: 1986-11-07
Granted: 1991-12-17
Abstract: ABSTRACT OF THE DISCLOSURE           A method for fabricating a solid-state image pick-up device changes part of the constituent elemental Si into the n-type impurity phosphorus P, thus changing the substrate to an n-type, by atomic transmutation through neutron irradiation of a p-type silicon Si wafer, and thus produces a Si substrate with a resistivity ?s of 10 to 100 ohm-cm. or preferably 40 to 60 ohm-cm.  A solid-state image pick-up device with a plurality of photosensors and vertical and horizontal shift registers as set forth above is then fabricated using the resulting Si substrate. In the preferred process, the silicon substrate can be obtained by irradiating a wafer sectioned from a crystal grown by the MCZ method, for instance, with neutrons as described before until it has the required resistivity ?s.  This silicon substrate is preferably of a p-type before neutron irradiation, that is, in the crystal growth state, and its resistivity ?o is then ten or more times higher (100 ohm-cm. or more) than that ?s obtained following neutron irradiation.  For instance, if ?s is to be 40 to 50 ohm-cm., ?o should be 680 to 1180 ohm-cm.          Then, n-type impurities, e.g. phosphorus P are generated by neutron irradiation to convert the silicon substrate to n-type with a low resistivity of ?o = 10 to 100 ohm-cm., or of 40 to 50 ohm-cm.

Abstract: ABSTRACT OF THE DISCLOSURE         A hydrocarbon-bearing strata in a hydrocarbon producing well is fractured using a fracture pressure which will not propagate the fracture into adjacent overlying and underlying non-producing strata.  The least principal  -compressive stress S3 of the hydrocarbon bearing strata and the adjacent overlying and underlying strata are determined by the relationship   where S1 is the maximum principle compressive stress, PF is the pore fluid pressure, and u is the coefficient of friction. The fracturing pressure is selected to be greater than S3 for the hydrocarbon bearing strata but less than S3 for the adjacent overlying and underlying non-producing strata. Hydrocarbon bearing formations suitable for hydraulic fracturing can also be identified.

Title: Method and apparatus for eliminating apparent offset in the servo code in a magnetic disc drive
Inventor: BELL R FRANK
IPC: G11B5/596
Filed: 1987-04-30
Granted: 1992-02-04
Abstract: Abstract This method and apparatus for eliminating apparent offset  in  the  servo code adjacent to a guard  band  on  a magnetic  memory disc utilizes at least two phases of  servo code per magnetic  cell for seeking and track centering,  or track  following,  operations and two phases of  guard  band code  per magnetic cell.   The two phases of guard band code are each either in phase or similarly out of phase with  the respective  phases of the servo code in individual  magnetic cells.         Phase  locking on a selected phase of  guard  band code  is  achieved by providing a synchronizing code in  the guard  band using an irregular pattern of guard  band  code, providing  a timing signal count representing a cell  count, for example,   decoding the synchronizing code to provide an end  of code signal and utilizing the end of code signal and a  predetermined cell count signal to achieve phase  locking on the correct phase of the guard band code.

Abstract: ABSTRACT OF THE DISCLOSURE A golf article retaining device adapted to be removably attached to a supporting surface.  The device is formed of an elongated strip of spring material in a three leg configuration.  The first leg has a free end and is bent at the other end into the second leg overlying the first leg to form a mounting recess adapted to receive the upper end of the supporting surface therebetween.  The configuration of the mounting recess substantially conforms to the supporting surface and insertion of the supporting surface into the recess will force the first and second legs apart whereby the tendency to return to the relaxed configuration will resiliently mount the device on the supporting surface. The third leg extends from the end of the second leg opposite to the end connected to the first leg, and overlies the second leg on the side opposite to the side facing the first leg.  The second and third legs are resiliently displacable from one another to permit insertion of a golf score card therebetween.  A receptacle is on the device for receiving and retaining a marking implement.  The recess between the second and third legs is open to permit use of the device with a variety of different size golf score cards.  Appropriate projections are on the first, second and third legs to facilitate engagement and holding of the device to a supporting surface and to retain a golf score card thereon.

Abstract: Title: A chain conveyor, a conveyor chain and a bend segment for the track of such chain conveyor.     ABSTRACT      A chain conveyor is described, which comprises a track including at least one bend zone and a conveyor chain. The track comprises two spaced parallel rails over which the chain can move. The chain has links presenting a substantially rectangular carrying surface made of synthetic plastics material and a connecting system situated below the carrying surface and including hinge eyes on opposite sides of each link and a hinge pin of ferromagnetic material passed through the hinge eyes of each pair of adjacent links, thereby hinging adjacent links together. The chain is capable of flexing not only about the hinge pins but also in the plane of transport defined by the carrying surfaces of the successive links. Guide surfaces depend from the underside of the carrying surfaces for guiding the chain laterally relative to the rails. The maximum perpendicular distance between these guide surfaces is shorter than the minimum perpendicular distance between the guide surfaces formed on the rails. Exclusively in the bend zones of the track, in the space between the two rails, under the connecting system of the links, means are provided for generating a magnetic field to exercise attraction on the hinge pins and thereby to hold the chain flat on the rails in the bend zone.
