Title: Suspension device for vehicle
Inventor: TATEMOTO MINORU
IPC: B60G17/04
Filed: 1988-11-29
Abstract: PURPOSE:To keep the set height which was kept hitherto at the time of the failure of pressure on an oil pump side by making a pilot valve set a recirculating passage from an oil pressure source to a reservoir at the time of detecting that the oil pressure which is set at the oil pressure source is lower than a defined value. CONSTITUTION:When the engine speed or oil pressure value of an engine is below a defined value, a bypass valve 10 is set at an initial condition in accordance with the setting of time by a timer to form a recirculating passage to a reservoir 9 and, in this condition, a check valve 13 is closed by means of a pilot pressure from the valve 10. Thereby, the recirculation of oil from a hydraulic actuator 2 is prevented to maintain the height. Also, by judging whether,e.g., one second elapsed from the point of time of carrying out such action of the valve 10, the operation of a control valve 7 is stopped. Hence, at the time of the failure of oil pressure of an oil pump, the set height which has been kept hitherto can be maintained as it is merely by closing the check valve 13.

Title: Automatic gain control circuit for antenna tuning circuit
Inventor: OHASHI TAMAKI
IPC: H03J3/06
Filed: 1986-12-19
Abstract: PURPOSE:To remarkably improve the aberration of a tuning point due to the power of electric field strength, by controlling the number of the passing magnetic flux of a third magnetic path on which a tuning coil is wound by varying the currents of input coils and suppression coils wound on first and second magnetic paths respectively. CONSTITUTION:Since the conducting resistance of a control circuit 6 is lowest when an input signal from an antenna 5 has a micro electric field, the input signal is only permitted to flow on an antenna coil 2, and also, both ends of the suppression coil 3 is short-circuited, which generates a magnetic resistance, therefore, a magnetic flux generated on the coil 2 circulates passing exclusively through the magnetic path 1c, thereby, the input signal is transmitted to the tuning coil 4 almost without being attenuated. When the input signal is increased, the conducting resistance in the circuit 8 is increased, and since the input signal flows from the coil 2 to the coil 3, the magnetic resistance in the magnetic path 1b is lowered, and the magnetic flux generated in the coil 2 also passes through the magnetic path 1b, then, the number of magnetic flux passing through the magnetic path 1c is reduced gradually. And when the magnetic resistance in the magnetic path 1b goes to the minimum level and the number of passing magnetic flux through the magnetic paths 1a and 1b are balanced, a magnetic circuit 1 forms a balancing bridge circuit, and no input signal is transmitted to the coil 4.

The circuit 9 executes comparison with the setting temperature of a temperature range setting signal 15 and when the temperature in the enclosure exceeds this setting temperature, a temperature abnormality signal 14 is sent to a logical gate 4 as truth on logic and the gate 4 is closed. At such a time, for example, even when a writing instruction 11 is outputted from a controller 7 and writing allowance 12a is outputted from a CPU5, the writing allowing signal 12b of the output of the gate 4 does not go to the truth on the logic and the writing is not executed. Then, data, which can not be read at the normal temperature, can be prevented from being recorded by the writing at the abnormal temperature in advance.
