IPC: F15B11/00
Filed: 1990-06-15
Abstract: PURPOSE:To prevent actuator operation speed from being sudden fluctuation accompanying a composite operation when at least one of a plurality of hydraulic actuators is detected to be inoperative by limiting the set differential pressure of a pressure compensating valve related to the corresponding direction change- over valve to a predetermined value smaller than the maximum value in the operation. CONSTITUTION:When a specified hydraulic actuator 5 or 6 to be detected about whether or not it is operated by an operation detector 27 is inoperative, a set differential pressure value of a pressure compensating valve 9 or 10 related to the corresponding direction change-over valve 7 or 8 is limited to a predetermined value smaller than the maximum value of the compensating valve in the operation according to a signal value of the operation detector 27. When the composite operation of the other actuator and specified actuator is intended, an opening amount of the pressure compensating valve 9 or 10 in the start of the latter is held to be small to restrain flow, so that the flow supplied to the former accompanying the restraint is prevented from the abrupt reduction and the operation speed or the like can be prevented from sudden fluctuation.

Title: Current mirror circuit
Inventor: KAWAI RIYUUICHIROU
IPC: G05F3/26
Filed: 1988-06-23
Abstract: PURPOSE:To eliminate the error due to base currents by providing another transistors TRs cascaded between a reference potential source and the base of a TR as a current source and adding base currents of another TRs and compensating the reduction of the current flowing to the TR with base currents of another TRs. CONSTITUTION:The base current of a TR 16 as the current source is supplied through a TR 19. When current amplification factors of TRs 18 and 19 are equal to beta, equal base currents flow because equal collector currents flow. That is, since a base current IB1 of the TR 18 is added to a current I flowing to a constant current source 14 at a connection point A between the collector of a TR 11 and the base of a TR 13, the collector current of the TR 12 is increased by IB1 to become I+IB4. The collector current of a TR 16 is equal to the current obtained by subtracting a base current IB2 of the TR 19 from the collector current of the TR 12. Since base currents IB1 and IB2 of TRs 18 and 19 are approximately equal to each other, the collector current of the TR 16 is I and is equal to the current flowing to the constant current source 14.

Abstract: PURPOSE:To increase the reading/writing speed of the data on each color by reading and writing the data stored in a memory in parallel with each other by (m) bits every (k) bits. CONSTITUTION:In a mode where the data are read and written in parallel with each other every (n) bits, a 1st bidirectional buffer gate 31 is activated and the n-bit data are read and written in parallel for the same address via (n) pieces of memory elements M1-M16. In a mode where the data are read and written every (m) bits, a 2nd bidirectional buffer gate 32 is activated and the (m) bits are read and written every (k) bits out of the (n) bits for the same address. Therefore n=9 is defined, for example, and at the same time three pairs of drawing data on the R (red), G (green) and B (blue) are allocated to a single address. In such a case, the drawing data on the color equivalent to three picture elements can be read and written at one time in a read/write mode for the parallel n-bit unit. Thus the drawing data, etc., can be read and written at a high speed.

Abstract: PURPOSE:To provide the learning method for environment dependent type phoneme HMM(Hidden Markov Model) which is small in the offset of learning data while maintaining the advantages of the HMM. CONSTITUTION:In a step 6, a word (or paragraph or sentence) HMM is learnt and in a step 7, it is decomposed into environment dependent type phoneme HMMs. Further, those environment dependent type phoneme HMMs are reconnected in a step 9 to generate the word HMM. The learning. decomposition, and connection learning are repeated to learn the environment dependent type phoneme HMMs. Then parameters at the center parts of the environment dependent type phoneme HMMs are replaced with parameters at the center parts of environment independent type phoneme HMMs corresponding to them in a step 11. Consequently, the properties of phoneme stationary parts can be maintained and the offset of the learning data is reducible. Further, parameters in the states of both ends are left as they are to maintain the ability to describe ahead of and behind phonemes on environment.

IPC: G01N24/00
Filed: 1990-06-15
Abstract: PURPOSE:To enable useful medical diagnosis by applying an inclined magnetic field for reading enough to detect a reduction in a coherency of a magnetic resonance signal to accomplish a non-invasive measurement and a display of a temperature distribution at a specified point within an object to be inspected without intrusion through the detection of a temperature at a specified part. CONSTITUTION:In an inclined magnetic field for reading, for example, a specified dephasing pulse 41 and a rephasing pulse 42 are contained to allow the detection of a reduction in coherency of a MR signal. As a result, a thermal motion of a nuclear spinning related to the reduction in coherency, namely, a temperature of a part in vivo can be measured without invasion. With a reconstruction of an image using these measurement data thus obtained, a temperature distribution at an optional location of in vivo can be displayed as two- or three-dimensional image. This enables the non-invasive diagnosing of various inflamed parts with a display of a temperature change in tissues in a human body on a screen.
