Title: Safety device for high lift working vehicle
Inventor: YAMAGUCHI NOBUYUKI
IPC: B66F11/04
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To exactly judges as to whether a working vehicle is capable of traveling or not on a difference in level in an advancing direction of a vehicle body and to safely pass the vehicle through a travelable difference in level without falling down. SOLUTION: When a vehicle body 10 is traveled, the size of a difference in level on the ground in front of an advancing direction of a vehicle body 10 is detected by an infrared ray sensor 44 and a difference in level part 32 of a controller 30. A safety speed calculating part 34 calculates safety speed based on the size of the difference in level detected in this way and a position of a work bench 16 detected by detecting devices 41 to 43 and a position calculating part 32 for the vehicle body 10. A comparison part 35 compares the safety speed and traveling speed of the present vehicle body 10 and outputs an alarm signal when traveling speed of the present vehicle body 10 is more than the safety speed.  When the alarm signal is outputted, a regulating part 36 receives the signal, controls a valve control part 31 and reduces speed up to speed that the vehicle body 10 is capable of traveling on the difference in level.

Title: Data processor
Inventor: TAKAYANAGI MASAHIRO
IPC: G06F5/06
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce the number of independent networks and realize the high speed operation by a method wherein a 3-state buffer is used for the control of the outputs of the respective registers of an FIFO and the outputs of the respective registers are made to be ahead of the output of a register which reads the control of a control signal and stabilized first. SOLUTION: A 32→8 Bit selector 209 selects the data to be outputted among data stored in registers 0-7 and, at the same time, switches the width of the data from 32 Bit to 8 Bit which is used afterwards. An output control signal generating block 210 generates output control signals and an FIFO reading and writing counter controls the selection of an FIFO into/from which data are written/read. The outputs of the registers are made to take three states and are connected to each other. The outputs are controlled every 16 Bit and the next data are outputted beforehand. With this constitution, the number of independent networks can be reduced and the high speed operation can be realized even if the output of a register which requires a long time for stabilization of the data output is connected by wired OR method.

Title: Active noise controller
Inventor: NAKAJI YOSHIHARU
IPC: G10K11/178
Filed: 1989-12-29
Abstract: PURPOSE:To reduce noises generated by a noise source by updating the filter coefficient of an adaptive filter so that noises at an observation position are minimum. CONSTITUTION:Noise generation state detecting means detect the noise generation states of plural noise sources and their detected values are inputted as reference signals to adaptive filters which are arranged individually as many as control sound sources. The outputs of the adaptive filters are added in control sound source units by a control sound source driving means and supplied to the control sound sources, which therefore generate control sounds based on the driving commands. At this time, a filter coefficient update means the updates the filter coefficients of the adaptive filters according to the detected values of residual noises at the observation position by residual noise detecting means and the detected values of the noise generation state detecting means so that the noises at the observation position become minimum. Consequently, even when there are plural noise sources, the noises at the observation position can accurately be reduce by interferring with the control sounds.
