Abstract: EXPENDABLE DIAMOND DRAG BIT     Abstract of the Disclosure Drag-type drilling bits are disclosed which have at least one blade and a plurality of fluid flow channels incorporated in the blade for conducting drilling fluid or drilling mud from the hollow interior of the bit to discharge or ejection ports located in the front cutting edge of the blade.  Rods of diamonds or of like "hard" cutter insert materials are incorporated in the blade in such a configuration that as the blade wears away or erodes and small pieces of diamonds are lost during drilling, more diamonds are exposed to the formation for drilling.  During erosion or wear of the blades, the fluid discharge ports continue to operate to eject drilling fluid adjacent to substantially each diamond rod, whereby the flushing away of cuttings and cooling of the diamonds is greatly improved.          In some embodiments of the invention rods of alternating hard and soft materials are also disposed substantially parallel with the diamond or like "hard" cutter insert, rods.          When the soft material of the rods is exposed for drilling the formation,  kerfs are formed which are thereafter "chipped away" by the subsequently exposed hard material of the rods.

Abstract: DIRECTION SENSITIVE OPTICAL SHAFT ENCODER               ABSTRACT OF THE DISCLOSURE         A direction sensitive optical shaft encoder includes an optical shutter disk mounted to a shaft for rotation therewith, the optical shutter disk bearing at least first and second radially concentric tracks having alternating light transmissive and light blocking areas formed thereon.  The light transmissive and light blocking areas of one track are angularly offset with respect to the light transmissive and light blocking areas of an adjacent track.  A pair of light emitters and light detectors are disposed on opposite sides of the optical shutter disk and aligned with the first and second concentric tracks, respectively.  Because the pattern of light transmissive and light blocking area on the two tracks are angularly offset, the output of the light detectors follows a unique pattern which is dependent upon the direction of rotation of the optical shutter.  The frequency of repetition of the pattern of outputs by the light detectors is indicative of the speed of rotation of the optical shutter.  A suitably programmed microprocessor can be used to detect the frequency and pattern of outputs of the light detectors to determine the angular speed of rotation of the optical shutter and its direction of rotation.  If the pattern of detector outputs does not follow an expected pattern an alarm condition is generated indicative of a failure of one of the light emitters and/or light detectors or possible tampering with the optical shutter.  The optical shutter may be used, for example, to determine the angular speed and direction of rotation of the eddy disk of an electricity meter.

Abstract: Abstract of the Disclosure:        In a radio communication network comprising a base station (11) and a plurality of wireless telephone sets (12) each of which is communicable with the base station by the use of a plurality of speech radio waves and a control radio wave, a control wave monitoring circuit (22) is included in the base station to monitor the control radio wave on transmission of an allocated one of the speech radio waves and to determine whether or not interference occurs in the control radio wave due to the transmission.  On occurrence of such interference in the control radio wave, the allocated speech radio wave is changed to another speech radio wave under control of a line control portion (15).  When the control radio wave is divisible into a down control channel directed from the base station towards the wireless telephone sets and an up control channel directed from the wireless telephone sets to the base station, the control wave monitoring circuit monitors the down control channel.  Alternatively, the up control channel may be monitored by the control wave monitoring circuit. Each of the wireless telephone sets may be either a cordless telephone set or a mobile telephone set.

Title: Lithographic image size reduction
Inventor: GIAMMARCO NICHOLAS J
IPC: H01L21/266
Filed: 1987-10-13
Granted: 1989-02-28
Abstract: Disclosed is a process for reducing lithographic image size for integrated circuit manufacture. A mask of photosensitive material having an opening of a minimum size dictated by the limits of lithography is formed on a substrate. Reduction in the image size is achieved by establishing sidewalls to the interior vertical surfaces of the opening by depositing a conformal layer, followed by anisotropic etching. The dimension of the opening is reduced by the combined thickness of the two opposite insulator sidewalls. In a specific direct application of the disclosed process, a photomask/stencil having a pattern of openings of a minimum size smaller than possible by lithography, per se, is formed.

The emitter of the transistor is connected to the negative pole of the supply unit, while one switching point of the switch-inductance is connected to one of the inputs of the NAND-gate having several inputs. There is a magnetic coupled control coil arranged in the system being common for the switch-inductance and the uncoupling coil, while there are as many circuits of identical layout consisting of the switch-inductances, the single abjusting resistors and the transistors, as the number of pulses required for the control. The NAND-gate is connected through a switch-amplifier to the control input of the inverter.

Abstract: An arrangement for adjusting the speed of in particular an excavator engine, which is to work at a speed adapted to the work to be done, and which is automatically changed to idling speed when there is no work to be performed. In this way, the fuel consumption and the disruptive effect of unnecessarily high noise levels are reduced. The adjustment arrangement consists of simple electronic control units and actuates the means 7 controlling the fuel of the engine by a DC motor 1 connected to said fuel-control means 7 being provided with a reference signal which corresponds to the desired engine speed. On manual actuation of a push-button 16 on the control lever, the arrangement affords the possibility of manually setting the speed up or down to at least 3 levels W1, W2, W3. The arrangement also comprises an idling speed unit 3 (no-load unit) which has a predetermined high z1 and a predetermined low z2 engine speed. If the manual control members of the machine are not actuated within a given short period of time, the unit 3 brings about high z1 idling speed, and if the manual control members are not actuated within a further period of time, it brings about a low z2 idling speed. On actuation of any of the manual control members, the machine resumes the relevant working speed. <IMAGE>
