Title: Hydraulic drive device for civil engineering and construction machine
Inventor: KAJITA YUSUKE
IPC: F15B11/05
Filed: 1989-01-23
Abstract: PURPOSE:To improve work efficiency by employing a control force restricting means for restricting the magnitude of the control force for driving a divided flow compensation valve in relation to a relief valve to a specified value capable of maintaining the opening of the compensation valve to a specified opening. CONSTITUTION:A calculating section 56 reads a load sensing differential pressure and a selection signal from a selection device 59a via an input section 55 of a controller 59. When the selection device 59a is in operation, before starting for example digging work by the compound drive of a boom cylinder 26 and a bucket cylinder 28, a control force corresponding to the differential pressure is obtained in the calculating section 56, and a signal commensurate with the control force is outputted to a drive section of a solenoid valve 62. When the circuit pressure rises to a relief pressure and the differential pressure reaches a target differential pressure during the digging work, the control force is restricted to a compensation control force smaller than the forces of spring 48, 50. Further, a constant control force is given to drive sections 38b, 40b of divided flow compensation valves 38, 40 and the valve 38 is maintained to a specified opening capable of supplying a flow rate at which the cylinder 26 can be operated.

Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To instantaneously distribute a different code for each request by preliminarily generating and storing a data conversion code, when a data conversion code generating request does not exist and setting a data conversion code from among stored data conversion codes, when a data conversion code generation request exists. SOLUTION: A state-managing means checks the existence/absence of a request for key generation from a user. When the request for key generation does not exit, a key-generating means generates beforehand a key from key generation information, such as encryption algorithm and a key size. A key- checking means checks the effectiveness of a generated key such as the duplication with already generated keys, and a key decided as being appropriate for managing is stored by a key-managing means. When there is a request for key generation from a user, the state managing means recognizes the request and a key acquiring means acquires a code among keys stored by the key managing means according to prescribed acquisition reference. A key-setting means sets the acquired key to a storage device such as an IC card.

Thereafter, the solution is filtrated by a membrane filter made of ethylene tetrafluoride to separate sludge. The sludge is then made to contact with an aqueous solution of hydrogen fluoride of a concentration of about 0.2W1wt% to dissolve silica which is the major constituent of the silica-alumina catalytic component in the sludge. Then, the Si ion is measured by a so-called molybdenum blue method in which ammonium molybdate is added at pH value of about 1.5 to cause a coloring of molybdenum yellow and then a reduction agent is added to cause a reduction into molybdenum blue the blue color of which is measured by colorimetric method. Practically, the amount of Si, i.e. the amount of catalyst, is measured by working curve.

Title: Control system for suppressing action of fm echo distortion
Inventor: DATE KUROSHI
IPC: H04B1/10
Filed: 1981-01-30
Abstract: PURPOSE:To increase the working limit, by discontinuing the calculation of the reflected wave constant and the control to suppress an FM echo distortion by means of the differential value of the instantaneous frequency of an input signal or the differential value related to the envelope time of the input signal. CONSTITUTION:The output signal of an instantaneous angular frequency deviation DELTAomega(t) taken out of a frequency discriminator 4 is applied to a differentiating circuit 9. When the changing factor of the instantaneous value of a space band signal becomes larger than the set value of a threshold circuit 11, the output signal is delivered from the circuit 11 to discontinue the calculation of the reflected wave constant carried out at a microcomputer 6 or to hold the control of the computer 6. As a result, the control is possible for the suppression of the echo distortion when the changing factor of the instantaneous value is small for the space band signal and the error of the calculated reflected wave constant is small. This suppression is also possible with the differential value of the envelope time of the input signal of an envelope curve wave detector 5.
