Patent number: 5001479Abstract: A method and circuit arrangement is disclosed for converting Gray code signals into counting pulses, forming a counter status, detecting interference signals infringing the Gray code and for forming an error signal with a network defining a finite automaton according to Moore or Mealy, wherein the network forms no error signal when a Gray code infringement is followed by a second Gray code infringement. The disclosed network arrangement in one embodiment comprises a quadruple interpolator (quadrature decoder) for precision dimension measuring machines with optoelectronic scale scanning. Interruptions of the measuring procedure and errors are reduced by not generating an error signal when a Gray code infringement is followed by a second Gray code infringement.Type: GrantFiled: February 8, 1989Date of Patent: March 19, 1991Assignee: Wild Leitz GmbHInventors: Norbert Becker, Hans-Juergen Mueller

Patent number: 4998999Abstract: A steering column assembly includes a steering column having an upper steering column tube and a lower steering column tube which are telescopically connected at their lower and upper portions respectively, a stationary bracket fixed to a vehicle body and an energy absorption bracket fixed to the stationary bracket. The energy absorption bracket fixedly receives the upper steering column tube which extends therethrough. The energy absorption bracket gets plastically deformed in response to an impact load exceeding a predetermined value to allow the upper steering column tube to displace downward with respect to the lower steering column tube. The impact load is applied to the energy absorption bracket through the upper steering column tube in the direction along the axis of the steering column. The applied impact load is absorbed through the plastic deformation of the energy absorption bracket.Type: GrantFiled: July 25, 1989Date of Patent: March 12, 1991Assignees: Nissan Motor Company, Limited, Fuji Kiko CompanyInventors: Naoki Yuzuriha, Yoshimi Yamamoto

Patent number: 4999560Abstract: An electric motor running system consists of a photovoltaic array, an inverter for inverting output voltage of the photovoltaic array to AC voltage and automatically controlled so that the frequency is changed in accordance with the output voltage of the photovoltaic array, maintaining the ratio of the voltage to the frequency at a constant value, an induction motor operated by application of the AC voltage from the inverter, and a frequency increasing circuit for increasing the output frequency of the inverter instantaneously so that the motor produces the torque larger than the load starting torque when the motor is started and further decreasing the increased output frequency of the inverter to the normal running frequency after the increased output frequency is maintained for a predetermined period of time. This construction allows the motor to be smoothly started even where a load connected to the motor is a positive displacement pump which has a large static friction torque.Type: GrantFiled: December 30, 1988Date of Patent: March 12, 1991Assignee: Kabushiki Kaisha ToshibaInventors: Yoichi Morishima, Kazuo Kobayashi, Isao Suzuki

Patent number: 4998357Abstract: The binocular telescope has in each barrel a focusing member (internal focusing) which is joined to a support guided on a guide rod. When a control knob is actuated, this support is displaced axially by means of a transmission bar. A driving pin, which engages into the focusing member, is integrally formed on the support for this purpose. A spring which interacts with the driving pin and acts upon the focusing member effects tilt-free guidance and prevents radial play, even with short guide lengths of the focusing member.Type: GrantFiled: December 22, 1989Date of Patent: March 12, 1991Assignee: Leica GmbHInventors: H. Peter Farnung, Alfred Hengst, Heinz Keiner

Patent number: 4999838Abstract: When a peripheral control processor is put, in a data processing system, into a down state from a normal state of operation upon occurrence of a failure, a failure recovery informing arrangement comprises a failure occurrence signal producing circuit for delivering a failure occurrence signal to a diagnostic bus. Detecting the failure occurrence signal, a detecting circuit delivers a detection signal to a system bus. Responsive to the detection signal, a recovery command signal producing circuit delivers a recovery command signal back to the system bus rather than, through a specific hardware line, directly to the peripheral control processor. Instead of the specific hardware line, a processing circuit is used in processing the recovery command signal into a peripheral initializing signal and a recovery informing signal to supply them to the peripheral control processor through the diagnostic bus. The initializing signal is for turning the down state to the normal state.Type: GrantFiled: July 20, 1988Date of Patent: March 12, 1991Assignee: NEC CorporationInventor: Akinori Horikawa
