An acoustic method and apparatus for investigating an earth formation penetrated by a borehole are described. Acoustic transducers are mounted on a tool to accurately determine the distance between a segment of the tool and the wall of the borehole. The acoustic transducers are positioned in such manner that the stand-off distance between individual resistivity measuring electrodes in an array, wh...

A clamp for a safety ski binding has a housing adapted to be secured to a ski and formed with a part-spherical seat. A pin has a ball head in the seat for swiveling of the pin within the seat. An abutment surface on the housing lies in a plane passing substantially through the center of curvature of the seat and a pressure element slidable on the pin has an end face engageable against the surface ...

PURPOSE:To report the presence or the absence of abnormality of an output device from a computer to a user, by detecting an undefined code sent to the output device by a controller and reporting the detection result to the computer. CONSTITUTION:In case that a CPU1 selects a controller 2 and tries to transmit data to a typewriter T/W4, the abnormality is reported to the controller and the controll...

PURPOSE:To check the contents of an ROM by regarding an arithmetic value calculated according to the program of the ROM right after power-on as a reference value, and comparing a value calculated according to the program of the ROM when a CPU does not uses a bus with the reference value. CONSTITUTION:A bus idle detecting circuit 7 detects the CPU is not using the bus 6. An ROM address output circu...

The invention relates to a method for reducing the background luminosity in the lower image region of a gas-discharge display panel. This method is intended to avoid reducing the display screen brightness. The invention provides that the plasma is sampled after the end of the image (lower image region) backwards with respect to the first cathode. The method according to the invention is used in th...

1462791 Television recording and playback MCA DISCO-VISION Inc 15 Feb 1974 [20 Feb 1973] 7021/74 Heading G5R A video recording made by a modulated laser beam is read by a second laser beam distinguished from the recording beam by having a different wavelength. As shown, a beam 40 from an argon ion laser 30 is modulated by video signals in a Pockels cell 32 and passes via a Glan prism 38 and a micr...

A toothed belt constituted by an annular body of elastomeric material, having a structure that is resistant to tensile stress embedded therein and having a toothing on one of its faces. The teeth of said annular body have at least one slot corresponding to their own top.

A process is described for increasing the space time yield of polymer production in a fluidized bed reactor employing an exothermic polymerization reaction by cooling the recycle stream to below its dew point and returning the resultant two-phase fluid stream to the reactor to maintain the fluidized bed at a desired temperature above the dew point of the recycle stream.

To eliminate welded or soldered connections between the fine or thin secondary wire (18, 18a) of an ignition coil and the high-voltage terminal plug, the high-voltage terminal arrangement includes a tubular stub (19) having a conical opening (29) therein, within which the end portion (18a) of the secondary wire can be placed, preferably in form of twisted-together loops (28), and the connection is...

PURPOSE:To provide a lubricating device for a ball-and-roller bearing, which can circulate grease by disposing seal members having a grease reservoir on both end surfaces of an outer race, and inclining a gap between the inner peripheral surface of the seal member and the outer peripheral surface of an inner race member so that rotation of the bearing causes air to flow into the interior of the be...

PURPOSE:To achieve an excellent following property as to the axial displacement of a rotary shaft and its displacement perpendicular to the axial direction, by interposing a funnel-shaped rubber-like elastic packing between a rotary slide ring and a housing fitted on the rotary shaft. CONSTITUTION:A rotary slide ring 6 is loosely fitted on a rotary shaft 1 by an engaging means 11 and indirectly he...
