Granted: 1996-04-02
Abstract: A working machine for use in a working system in which a pair of working machines, which are capable of traveling both on land and on a riverbed or the like, are respectively used for excavating gravel or the like on the bottom of the water and for transporting the same.  The working machine is basically constructed such that an upper structure including an operator's cabin is mounted on a lower structure having a self-traveling mechanism, such as endless tracks, in such a manner that the heightwise position of the upper structure can be varied.  The working machine is applied to a dredging machine for a shallow water area having an excavating mechanism juxtaposed in the vicinity of its upper structure, and to a transporting machine for a shallow water area having a load-carrying platform juxtaposed in the vicinity of its upper structure.  The upper structure and the excavating mechanism, as well as the upper structure and the load-carrying platform, are disposed in such a manner as to be capable of swiveling horizontally via a swivel base.  The use of the dredging machine and the transporting machine improves the work efficiency.

Title: Linear compensating circuit
Inventor: FUJITA NORIYUKI
IPC: H03G3/20
Filed: 1992-07-30
Granted: 1997-11-18
Abstract: A linear  compensating  circuit   is  provided  which comprises a first level detection circuit for detecting the level  of an input  signal to  an amplifier,  a second level detection  circuit  for  detecting  the level  of  an output signal from the amplifier, an amplitude compensating circuit for  controlling  the  amplitude  of  the  input  signal  in accordance  with the  difference  between  the  signal level detected by the first detection circuit and the signal level detected by the second level detection circuit for improving the  linearity of  an  input-output  characteristic  of  the amplifier,  and a phase compensating circuit for controlling the  phase of the input signal in accordance with the signal level detected by the second detection circuit.  This linear compensating circuit performs the compensations of amplitude and  phase  and  as a result, the degradation  of  phase characteristic  induced due to the compensation of amplitude can be prevented, resulting in a reduction in the distortion of an output signal  of the amplifier  even when it is being operated  in the vicinity  of the  saturation  range.  This linear compensating circuit is effective when applied to a power amplifier,   particularly to  a  high  frequency  power amplifier. It has a characteristic set preferably to cancel the phase change of  the output signal induced caused by the compensation of  amplitude  by  the  amplitude  compensating circuit.          .PA

Title: Rockbolt
Inventor: HOLLIS IAN
IPC: E21D21/00
Filed: 1993-02-16
Granted: 1998-05-05
Abstract: A rockbolt for anchoring in a borehole and then tensioning it has a nut at its proximal end whose screw threaded engagement with the rockbolt is utilised to force the nut against the  surface at which the borehole  is provided and cause tensioning of the rockbolt.  Initially, the nut cannot be run down the rockbolt owing to provision of a disc seated in a recess at the proximal end of the nut and which is only forced out from the recess when the nut is subject to a minimum predetermined torque.  Holding of the disc in the recess is achieved by deformations of the nut resulting in the perimeter of the disc being frictionally restrained.

Abstract: Novel cluster nozzle designs useful for the formation of atomized sprays of fine liquid droplets in a continuous gas phase are described. A plurality of individual gas-liquid mixing zones communicate with a common source of liquid and a common source of gas to form gas-liquid mixtures for spraying from individual orifices in the nozzle. An improved uniformity of spray pattern is attained, as well as the ability to effect a greater liquid output from the nozzle through the use of larger size or numbers of orifices, while retaining very uniform sprays, by effecting a degree of premixing of liquid and gas before passage to the individual gas-liquid mixing zones.

Abstract: ABSTRACT OF THE DISCLOSURE      An intermediate frequency (IF) converter converts a received signal to an IF signal.  A demodulator demodulates the IF signal to a demodulated signal and detects a phase error.  A frequency error detector detects a frequency error based on the phase error.  A modulated-carrier detector detects a modulated carrier component from the IF signal.   When the modulated carrier component  is  detected,  a  controller  achieves  a  frequency stabilizing operation based on the frequency error.

Abstract: Tubular saw tooth and mount assembly ABSTRACT OF THE DISCLOSURE           In one embodiment of saw tooth assembly, the tubular saw tooth is releasably inserted with friction fit inside the hollow of a tubular mount.   In an alternate embodiment, it is the tubular mount which is releasably inserted with friction fit inside the hollow of the tubular tooth.   In both cases, the hollows of the mount and tooth are coextensive, whereby a common axial through-channel is defined.   The tubular mount is to be anchored to the peripheral edge of a circular saw discoid plate.  Preferably, a bypass outlet is provided on the radially outward side of the tubular  mount.  The  wood  chip  generated  during  circular  saw operation can therefore freely engage through the common through-channel,  i.e.  through the whole saw tooth assembly, and escape therefrom.   Wood chip clogging of the saw tooth during sawing operations  is therefore  substantially  prevented,   and  the aerodynamic features of the circular are accordingly enhanced.
