Title: Vibration suppressing control device for operation device of hydraulic working machine
Inventor: YAMAGATA EIJI
IPC: E02F3/43
Filed: 1992-05-21
Abstract: PURPOSE:To suppress vibration of the operation device of a hydraulic working machine generated when the device is to be stopped or started, and provide possibility of acquiring a large acceleration at the time of speed change, for example at starting. CONSTITUTION:A control unit 7 calculates the thrust force F of a boom cylinder 2 from pressure signals given by pressure converters 8, 9 and also the speed V of the boom cylinder 2 from. displacement signals given by a displacement meter 10. The obtained values are passed through a high-pass filter to cut off vibration components below a specific frequency value and multiplied with gains in accordance with the normal component (load) of the thrust force acquired by passing the thrust force of the boom cylinder 2 through a low-pass filter which cuts off vibration components over specified frequency value, so as to generate a rate of flow command value DELTAq, and control signal is emitted. A flow control valve 11 supplies or exhausts a rate of flow corresponding to this command value to/from an actuator, as an assisting value, which is thus given a damper effect and suppresses the vibration.

Title: Intake and exhaust valve control system
Inventor: MORI KATSUYUKI
IPC: F02D41/22
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To provide an intake and exhaust valve control system that is capable of preventing any abnormal combustion including not only knocking but self- ignition and preignition as well in an internal combustion engine. SOLUTION: Upon a determination that an engine 201 is in a rapid acceleration state by an acceleration determination means 208, it is determined whether the conditions on which abnormal combustion occurs are met or not from detection values about the intake pressure, engine temperature, engine speed and air-fuel ratio. If the occurrence conditions are found fulfilled, a variable intake/ exhaust valve opening/closing timing mechanism 207 controls or retards the closing of the intake valves. The timing at which intake compression starts is thus delayed to lower the cylinder pressure or to prevent any unintended ignition phenomenon.  When the detection value of an engine speed detection means 204 thereafter indicates that the engine speed exceeds a prescribed value that avoids any abnormal combustion, the closing of the intake valves are returned or advanced to the original state before the rapid acceleration.

Title: Detector of angular velocity
Inventor: UIRIAMU ESU WATOSON
IPC: G01C19/5614
Filed: 1987-05-26
Abstract: PURPOSE:To enable the manufacture of the title device in a reduced manufacturing process and with an excellent yield, by a method wherein a piezoelectric element equivalent to a detecting element is disposed as a compensating element in proximity and in parallel to the sensor and signals from the two elements are detected differentially. CONSTITUTION:A driving element 27 is fixed to a fixed end 29a, and a sensor 31 is coupled thereto through the intermediary of a coupler 33 so that it intersects the plate surface of the element 27 perpendicularly. Moreover, a compensating element 35 is fixed to an fixed end 29b so that the plate surface thereof is parallel to the element 31. When the element 27 is made to vibrate freely in the direction of an arrow (d), a Coriolis force F''col generated by the rotation in the direction of an arrow (e) and a force F''EX due to a straight motion are applied to the element 31. Meanwhile, only the force F''EX is applied to the element 35. By detecting differentially electric charges applied to the elements 31 and 35, an adverse effect of external vibrations can be removed. Accordingly, the element 27 alone is made to vibrate freely in such a structure as the above, and therefore it is unnecessary therein to adjust the phase of vibrations by trimming or by selecting the piezoelectric element to be paired to the element 27.

Title: Protecting means of power switching element
Inventor: ZENITANI KENZOU
IPC: H03K17/082
Filed: 1982-07-28
Abstract: PURPOSE:To protect a power switching element from its destruction, by setting the power switching element under a nonconductive state when an unsaturated state is detected for power switching. CONSTITUTION:The voltage level of a detecting terminal 22 is low to have an unsaturated state in which an output transistor TR1 is not turned on since a resistance R2 is large excessively or approximate to an open state. Therefore a diode D1 is kept off. As a result, a detecting terminal 23 is kept at a high level. Thus the output waveforms of inverter circuit 10 and 24 are set at a high level and a low level, respectively. Therefore the output waveform of an exclusive NOR circuit 26 is set at a low level, and the output of an inverter circuit 7 is set at a high level. Thus a TR3 is turned on, and the TR1 is kept under a cutoff state. When the TR1 is set under an unsaturated state owing to the lack of its base current, the diode D1 is kept off. Therefore, the terminal 23 is set at a high level, and the output of the circuit 7 is set a low level. As a result, the TR3 is saturated for a full period to cut off the TR1.
