Abstract: A disk cartridge loading and ejecting mechanism for a recording/reproducing apparatus has: a cartridge holder for receiving a disk cartridge which is movable between a cartridge loading position and a cartridge ejecting position; a loading lever for moving the cartridge holder to the cartridge loading position; a protrusion provided at a side portion of the loading lever and moved integrally with the loading lever; a lock lever having an engagement portion with which the loading lever engages and an abutting portion on which a forward end of the disk cartridge is able to abut and for locking the loading lever in the ejecting position and the loading position; a sliding plate having a first and a second slanting cam portion with which the protrusion is engageable and being movable in the direction along which the disk cartridge is inserted and discharged; an ejection operation section connected to the sliding plate for moving the sliding plate in the disk cartridge insertion direction; and an elastic member fo

Abstract: A recording medium driving device is disclosed. The recording medium driving device is equipped with a tray on which an information recording medium is mounted, a rack interlocking with the tray, and a tray moving means inclusive of gears each engaging with the rack. This driving device effects the recording and/or the reproduction by loading the information recording medium on a medium driving means. The driving device further has a locking member for locking the rack to the tray and for intergrally moving both of them to a loading position of the information recording medium for the medium driving means; and a guide groove for guiding the lock member to a position at which the locking state is released after reaching the loading position. With this construction, it is feasible to reduce an optical disk driving device in thickness and to prevent it from suffering damages caused by malfunctions.

Abstract: In order to increase breakdown voltage of a planar junction of a semiconductor device, an oxide layer is provided on a portion of the surface of the semiconductor substrate and covers the junction at that surface, the oxide layer containing a charged ion region extending from the junction over a portion of the substrate, with the polarity of the ions being the same as the polarity of the substrate region over which the oxide layer extends.

Abstract: A fusible link structure and method of making the same for use in integrated circuit structures is provided in which the fusible link comprises, in one embodiment, an alloy of platinum and silicon. The preferred alloy comprises the eutectic mixture having approximately 23 atomic percent silicon. Electrical connections to the fusible link are preferably provided by a layer of aluminum on a layer of material, preferably an alloy of titanium and tungsten wherein the titanium and tungsten alloy is disposed between the fusible link and the aluminum layer, and serves as a diffusion barrier for preventing diffusion of the aluminum into the fusible link. In a preferred embodiment, a fusible link is deposited on a relatively thick dielectric layer, preferably more than 10,000 .ANG. thick, having a relatively low thermal conductivity.

Abstract: A programmable array logic cell 60 including a sum-of-products array having a single OR gate 70 for providing a sum signal, and including an XOR gate 80 for combining the sum signal with a product signal provided by an AND gate 78 from selected array input and/or feedback signals. The product signal can be the previous state output signal Q for a JK flip flop configuration, or a forced high or low signal for other configurations for programmable output signal polarity.

Abstract: A method of fabricating a semiconductor device capable of handling high voltages includes forming a relatively thick epitaxial layer the top surface of which defines a plurality of generally V-shaped grooves, a pair of the grooves having formed therebetween active device regions, such pair of grooves acting as isolation regions including impurity regions extending on both sides of the groove through the epitaxial layer to a lower layer. A pair of grooves formed inward of the first-mentioned grooves contact active regions of the device into which the V-shaped portions extend, again with each such V-shaped portion having impurity regions extending on both sides thereof. The impurity regions associated with the V-shaped grooves are formed simultaneously with other active regions of the device.

Abstract: The growth of a hydraulic fracture increases the period of free oscillations in the well connected to the fracture. Simultaneously, the decay rate of free oscillations decreases. The properties of forced oscillations in a well also change during fracture growth. All of these effects result from the changing impedance of the hydraulic fracture that intersects the well. Hydraulic fracture impedance can be defined in terms of the hydraulic resistance and the hydraulic capacitance of a fracture. Fracture impedance can be determined directly by measuring the ratio of down hole pressure and flow oscillations or indirectly from well head impedance measurements using impedance transfer functions. Well head pressure measurements can also be used to evaluate fracture impedance by comparing them to pressure oscillations computed with hydraulic models that include fractures with different impedances.
