Title: Signal coding device and method
Inventor: OZAWA KAZUNORI
IPC: G10L19/038
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To reduce the degradation of sound quality with a relatively small calculating quantity by combining the output signal of a parameter calculating means and the output signal of a coding means and outputting them. SOLUTION: An input signal is divided into plural pieces of bands every predetermined frame and spectral parameters (for example. LPC coefficients) expressing spectral envelopes are calculated from the input signal. Moreover, performance requirement values are calculated with respect to respective bands based on the spectral parameters in a performance calculating part 320. Further, the number of pulses for expressing sound sources in respective bands is adaptively assigned according to the performance requirement values in a assigning part 330. Then, a coding is performed by calculating pulses expressing a sound source according to the number of pulses in a coding part 400 and then the output signal of a spectral parameter quantizing means 210 and the output of the coding means 400 are combined in a multiplexer 500 to be outputted.

Title: Motion interpolation method using motion vector, motion interpolation circuit, motion vector detection method and motion vector detection circuit
Inventor: FUKAZAWA HIDEKAZU
IPC: H04N19/50
Filed: 1995-05-15
Abstract: PURPOSE: To reduce distortion around a still area with an image signal the motion of which is interpolated. CONSTITUTION: A still area detection circuit 12 detects an area including a still area in a moving area based on a motion vector detected by a motion vector detection circuit 10 and a zero vector replacement circuit 14 replaces the motion vector therearound with '0' vector. Thus, a field signal read out of motion correction memories 18, 20 and the motion vector of which is corrected at a motion vector correction circuit 16 at a field interpolation ratio αis read as a signal the motion of which is '0' around a still area in the motion area. As a result, an interpolation field signal outputted as a weight sum of a motion correction field signal and a motion '0' field signal from a weight sum circuit 32 is a signal in which a still area in the motion area is surely at a standstill and then the weight sum with its surrounding motion is avoided.  As a result, distortion due to spread of the still area to its surrounding or appearance of ghost in the still area is almost avoided in the image.

Title: Hitch control system
Inventor: GOODON KEI UIIGAATO
IPC: A01B63/111
Filed: 1984-06-06
Abstract: A hydraulic rockshaft actuator (24) operates a rockshaft (12) to raise and lower a hitch in accordance with mixed position control set by a lever (28) and draft control set by a lever (32). The set points established by these levers are combined mechanically with actual rockshaft position sensed mechanically by a ramp (14) on the rockshaft and actual draft load sensed hydraulically by a load sensor (34) and communicated to the mechanical combining arrangement (16) via a load control valve (17). In order to provide this known system with engine speed control (to avoid labouring the engine) and/or wheel slip control (to avoid excessive wheel slip), an electronic control unit (46) processes signals from corresponding transducers (54, 58, 60) and derives an electrical control signal. A pressure control valve (40) in the hydraulic line between the draft load sensor (34) and the load control valve (17) enhances the hydraulic load signal so that reduced engine speed and/or increased wheel slip emulates increased draft load and therefore leads to the hitch being raised. To this end the control valve (40) has electrical pilot control (44) responsive to the electrical control signal in parallel with hydraulic pilot control (42) responsive to the pressure from the draft load sensor (34). The draft control lever (32) sets the proportions of the mixed control and, within the control unit (46) the electrical control signal is gain-scaled in dependence upon a signal (A(6)) from a transducer (52) on the lever (32) so that the effect of the electrical control signal is the greater the greater the proportion of draft load control in the mixed control.

Abstract: PURPOSE:To prevent the reduction of access speed to a memory in a corresponding system and reduce the number of inter-system connection lines by providing both systems of a dual memory device with memory crossing parts and directly accessing the memory in the corresponding system and accessing the memory in the other system through memory crossing parts. CONSTITUTION:When a memory control part 2a writes data in a memory 1b, a memory crossing part 7a transfers an address (a) and data (d) from the memory control part 2a to a memory crossing part 7b.

When the memory control part 2a reads out data from the memory 1b, the memory crossing part 7a transfers the address (a) from the memory control part 2a to the memory crossing part 7b. The memory crossing part 7b reads out data (d) from the memory 1b and returns it to the memory crossing part 7a under the control of the memory control part 2b when receiving the address (a), and the memory crossing part 7a returns received data (d) to the memory control part 2a.

IPC: H04L7/02
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To guarantee the phase relationship of data and a clock to fluctuations of the clock and the phase relation by discriminating one clock length delay stage number that jumps to an optimum phase delay stage number when a selected delay number exceeds the maximum or minimum stage number due to the phase fluctuations of the clock or the data. SOLUTION: One clock length discriminating part 10 generates a periodic signal of one pulse through a counter part 11 and a decoding pat 12, fetches a periodic signal of one pulse which undergoes delay at a rise of the periodic signal of one pulse in a change point detecting part 13 and can find a change point by collating outputs of adjacent F/Fs 132. The change point comes to show delay quantity of one pulse and the number of stages becomes one clock length delay stage number. The one clock delay stage number obtained in this way is encoded so as to be used by a phase adjusting part 20 and an integrator 15 temporally balances one clock length delay stage numbers in order to suppress the variation of code values in a short time.
