Title: Work vehicle
Inventor: ISHIDA EIICHI
IPC: B62D27/04
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To prevent a swing of a cabin from becoming larger by making a suspension which supports a cabin to be switchable between a suspension activated condition and suspension locked condition. SOLUTION: An active type suspension SS is configured to be switchable between a suspension activated condition and a suspension locked condition. Running condition detection means 101 is provided with a supersonic sensor S4 as a road condition detection sensor for detecting irregularity of the running surface, and is configured so that it determines whether it is in a road running condition or in a working road running condition. In other words, if the irregularity of the running road is large such as a working place with a surface of soil, the amplitude of reflecting wave from the running surface is small. Contrary, if the irregularity of the running road is small such as an asphalt paved road, the amplitude of reflecting wave from the running surface is large. This enables the determination of the running conditions.

Filed: 1983-04-27
Abstract: PURPOSE:To improve compressibility greatly without generating large quantization distortion by imposing variable length encoding upon a combination of respective components obtained by the sum/difference conversion of an original picture element group or its forecasted conversion. CONSTITUTION:A sum/difference converter 2 calculates sum components S0 and E0 and difference components S1 and E1 from a luminance picture element group and a color difference picture element group as to picture elements in a block. A forecasting converter 3 calculates forecasted error components DELTAS0 and DELTAS1 of a luminance signal and forecasted error components DELTAC0 and DELTAC1 of a color difference signal from said components. Those forecasted error components are further quantized by a converter 3. Those quantized forecasted error components are encoded on variable length basis by an encoder 4 by using code constitution determined for respective quantization characteristics by the combination of the quantized values DELTAS0 and DELTAS1, and DELTAC0 and DELTAC1. The variable length code compressed by the encoder 4 is inputted to a buffer memory 5 successively to add such a redundant code that an error is corrected by an error correcting encoder 6, thereby sending the composite code to a transmission line.

IPC: H02P7/298
Filed: 1982-05-07
Abstract: PURPOSE:To shift from a power drive to a brake of an electric motor vehicle without interrupting a control by controllig a shunt field current with the same poles as those at the power drive time, at the brake time, controlling an armature current under the control of a shunt field current at a high speed time and under the both controls of the shunt field current and a chopper at intermediate and low speed times. CONSTITUTION:A contactor PK1 and series units P1, P2 of a power drive and brake shifter are closed at the forward power drive time, a shunt field current is controlled by ON or OFF of a gate turn-off thyristor GTO4, and an armature current is controlled by ON or OFF of a chopper GTOCH. A field current IP is increased under the control of the GTO4 to flow a regenerative current. The chopper GTOCH stops the ON or OFF control, opens the series units P1, P2, and closes series units B1, B2. When a motor speed is decelerated so that an armature induced voltage becomes lower than the power source voltage, the ON or OFF control of the chopper GTOCH is added.

Title: Tilt angle sensor
Inventor: TERAI TOSHIO
IPC: G01C9/20
Filed: 1987-03-25
Abstract: PURPOSE:To make the whole device compact and to improve its detection sensitivity by winding secondary-side detection coils around both leg parts of an open magnetic path magnetic core and fitting and holding a container which contains magnetic flux in an open magnetic path. CONSTITUTION:A primary-side exciting coil 3 is wound around the body part of the magnetic core 7 and the secondary-side detection coils 4 are wound around both leg parts of the magnetic core. The container 6 which contains the magnetic liquid 2 while a gap 5 is left, on the other hand, is fitted and held in the open magnetic path of the magnetic core 7. When this tilt angle sensor is in a horizontal state, pieces of magnetic flux cross-linked with both secondary-side detection coils 4 becomes equal in quantity, and voltages E1 and E2 induced across the secondary-side detection coils 4 are therefore equal, so that their composite voltage E3 becomes zero. If, however, the tilt angle sensor slants, the pieces of magnetic flux which pass sections 8 and 9 have a difference and different voltages E1 and E2 are developed across the secondary-side detection coils 4, so that the composite voltage E3 varies linearly with a tilt angle theta deg.. For the purpose, the composite voltage E3 is measured to accurately find the tilt angle of the body.
