Inventor: OLSON BRIAN R
IPC: B60D1/26
Filed: 1992-06-16
Abstract: TRACTOR HITCH          ABSTRACT        An attachment for coupling a drawbar to a tongue is mounted on the underside of the drawbar.  It includes a draw pin arm pivoted at the front end to the drawbar and carrying a draw pin at  its rear end.   To pivot the draw pin arm between released and set positions, it is equipped with a lifting  link pivotally connected to the arm and connected slidably to the drawbar.  Sliding movement of the link along the drawbar lifts or lowers the draw pin arm and hence the draw pin.  When the sliding connection reaches its limiting point with the draw pin set, an automatic lock drops into place to prevent release of the hitch until the operator deliberately releases the lock.

IPC: G06K15/00
Filed: 1992-08-28
Abstract: A power is supplied to a CPU without regard to an on/off-state of a power switch.  In the off-state, the CPU renders a control signal indicating that an apparatus does not accept data, to an active state or a high impedance state to inform to a host.  When data is received, the state is switched to the on-state for recording operation.  The received data is stored in a memory, and when the state is switched to the on-state, the data is read from the memory for recording operation.       In this manner, drop of record data due to data transmission from the host in the off-state of the power switch is prevented.

Title: Quadrature modulator for tdma/tdd radio communication apparatus.
Inventor: HARA TOSHIHIRO
IPC: H04M1/72502
Filed: 1992-09-16
Abstract: In a radio telephone apparatus of the TDMA/TDD system, signal transmission and reception are conducted by use of carriers having an identical frequency.  This leads to a problem that the transmission intermediate frequency carrier and the transmission RF carrier enter the receiver section in an identical housing, thereby causing a cochannel interference. To overcome this difficulty, there is disposed a frequency division modulator including a frequency divider for dividing by four a local signal having a frequency which is four times that of the intermediate frequency to obtain a carrier having a frequency shifted from that of the local signal by 90 ° . Signal to be modulated is subjected to an orthogonal modulation according to the carrier wave to produce an intermediate frequency carrier.   The operation of the modulator is stopped in a signal reception state to prevent the intermediate frequency carrier undergone the orthogonal modulation from being produced.

Abstract: A method and apparatus for drawing an optical waveguide fiber which minimizes fiber bow caused by differential stresses in the cladding layer of the fiber are disclosed. The fiber is drawn from a preform which is heated in a draw furnace. Gases introduced at the top of the furnace form a boundary layer adjacent to the fiber which passes through the furnace, along with the fiber, into a tube. The tube isolates the fiber from the ambient atmosphere so that the boundary layer of gases established in the furnace remains substantially uniform until the viscosity of the cladding layer of the fiber is high enough to minimize differential stresses around the circumference of the fiber.

Abstract: A method of allocating radio channels, between the base stations of a multi-base station radio system, uses a mathematical model of the radio system which is derived from an analog of the radio system. The analog is a thermal bath containing a plurality  of interacting particles, each particle in a particular spin state. The number of particles at a given location in the thermal bath, corresponding to the traffic demand at an equivalent location in the radio system, each occupied spin state corresponding to the particular radio channel. The model is operated by allowing the spin states to relax, by means of a stochastic reduction in temperature of the thermal bath, from an initial infinite temperature, to a minimum energy, which equates to an acceptable level of interference between radio channels, operated in the different cells of the radio system. The distribution of spin states at the minimum energy determines the allocation of radio channels. Apparatus for implementing the method includes a central control unit which runs the mathematical model and issues commands to the individual base stations allocating channels.
