Title: Hydraulic control device
Inventor: OINUMA YOICHI
IPC: E02F9/20
Filed: 1994-06-27
Abstract: PURPOSE:To conduct pressure control with high accuracy based on an input value in a small flow rate region where control flow rate is less than a specified value and switch from pressure control to flow rate control in a large flow rate region exceeding a specified value to conduct flow rate control with high accuracy based on an input value of the load pressure. CONSTITUTION:A valve means 51 is set in a circuit connecting a pump P and an actuator A. A valve opening control means 57 controls the opening of the valve means 51 according to a signal from a controller 56 and a signal from each detecting means. A means 59 which compares a flow rate calculated in a flow rate calculation means 58 with a specified value is arranged. A pressure control means 60 which controls the valve opening so that a pressure set value is conformed with load side pressure when the calculated flow rate is less than the set value is installed. When it exceeds the specified value, a flow rate control means 61 controls the valve opening so that a flow rate set value is conformed with the calculated flow rate. The flow rate control is accurately conducted and high operation capability is ensured.

Title: Magnetic recorder
Inventor: KAWANA JIRO
IPC: G11B19/20
Filed: 1994-06-27
Abstract: PURPOSE:To control small the movement of a shaft for the rotation of a magnetic recording medium which is caused by an external force such as an impact, reduce the size of a whole recorder and suppress the generation of errors. CONSTITUTION:A stepped pin 21 is fixed to the base of a shaft 4 for the rotation of a magnetic recording medium 12 through the hole 20 of a thrust receiver 3. The fall-off stopper 22 for the stepped pin 21 is applied to the shaft 4 in a direction opposite to the thrust receiving direction. At the time of normal rotation, the shaft 4 rotates while it is brought into contact with the thrust receiver 3. At that time, the fall-off stopper 22 is not brought into contact with the thrust receiver 3. If an external force such as an impact is applied in a direction C and the shaft 4 is moved in a direction C, the fall-off stopper 22 is brought into contact with the thrust receiver 3 to control the movement. The movement of the shaft 4 at that time is determined by the thrust of the normal rotation and a gap between the receiver 3 and the stopper 22 and it is necessary to take only the thickness of the receiver 3 and the precision of the fall-off stopper 22 into account, so that the gap can be set small.

Title: Magnetic recording and reproducing device
Inventor: TAKABE TETSUAKI
IPC: H04N5/7826
Filed: 1986-06-20
Abstract: PURPOSE:To eliminate the phase error between the reproduction signal and the horizontal synchronizing signal by always monitoring the recording and reproducing horizontal synchronizing signals and changing the phase of a cylinder to the recording signal as well as the constitution of a discharging circuit so as to eliminate the phase variance. CONSTITUTION:The framing of the recording signal is detected and the mono- multi output (c) of 1/2V width is produced from the framing detection signal (b). Then the mono-multi output (d) of about 10H is also produced. The phase difference between the horizontal synchronizing signal (h) of the recording signal and the horizontal synchronizing signal (l) of the reproduction signal is detected by an AND gate 11 in the 10H section. A single pulse (k) is continuously produced from a flip-flop consisting of a NOR gate until the signal is set at a high level. A transistor is turned on by the pulse (k) and a discharging circuit is formed together with the change of the fixed DC voltage. Thus the time constant of a mono-multi 5 is changed and the reference signal of a cylinder is changed up to maximum 1H. Thus it is possible to secure coincidence between the phases of horizontal synchronizing signals of the recording signal and the reproduction signal.

Title: Vehicle anti-lock device
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/48
Filed: 1987-06-11
Abstract: PURPOSE:To make it possible to reduce the discharge function of a pump by providing such an arrangement that the pump is not yet operated at the same time as the time of initiation of anti-lock operation while hydraulic oil may be fed into a brake device when the brake hydraulic pressure is reapplied. CONSTITUTION:During initiation of anti-lock control a subgate valve 27 feeds hydraulic oil into a first hydraulic chamber 34 in a main gate valve 21 and a sub-outlet hydraulic chamber 43 in the valve 27 until the brake pressure of a master cylinder 2 becomes equal to that in hydraulic chambers 34, 43. Accord ingly, although a pump 10 is not yet driven at the same time as the time of initiation of the control, the pump 10 may be driven when the pressure in an accumulator 6 is lowered below a set value, so as to increase the pressure up to the set value. Thus the discharge capacity of the pump 10 can be made to be low. Further, during control operation hydraulic chamber gammao, gammai in inlet and outlet systems are in an isolated condition, and accordingly, variations in hydraulic pressure in a brake device 6 during hydraulic brake operation, due to change-over of valves 23, 28 does never affect upon the cylinder 2 side. Thereby it is possible to prevent a kick-back phenomenon which causes transmis sion of variations in hydraulic pressure by a brake pedal.
