Title: Checking system for display tube segment of electronic price balance
Inventor: KUNO SHIROU
IPC: G01G23/37
Filed: 1978-09-13
Abstract: PURPOSE: To make it possible to accomplish the check at any time by using the negative weight signal, which is generated when a dish is raised, as a segment checking signal.  
     CONSTITUTION: If a dish is raised at any time during use, it is judged that the weight signal is under a negative condition as a result that the count number ZD stored is subtracted from the weight data WD. Then, the content of a display memory 14 is set at full scale 8. Thus, all the segments of a display device 9 are lit for a preset time, and the content of the display memory 16 has its full scale at an F code so that the display unit 10 is extinguished. Thus, it is possible to accomplish the check at any time during use. If, on the other hand, only the odd digits are lit and then even digits are lit and extinguished, the relaible check can be performed under the condition having no influence from the adjoining digit.

Abstract: PURPOSE:To enable the appropriate, rapid and automatic selection of a necessary key pattern even when an image is of relatively high magnification, by calculating the degree of approximation of each of a plurality of regions having a prescribed area in the image to be picked up, to a standard pattern. CONSTITUTION:A plurality of standard patterns are stored in CPU 50.

A cursor having a dimension corresponding to the picture elements of 32 X 32 is shifted for each one picture element, and the degree of approximation of a region prescribed by the cursor at each shift is calculated. Then, the whole of the image is scanned and the degrees of approximation are calculated with respect to all of the standard patterns. Based on multi-value digital signals stored in an image frame memory 48, concretely, mutual correlation values are calculated according to a prescribed formula, and the degrees of approximation are calculated on the basis of these mutual correlation values. Then, the region having the highest degree of approximation is extracted as the first proposed key pattern region.

Abstract: PURPOSE:To suppress engine stall in deceleration by increasing the idle air amount by a prescribed amount if a throttle valve is completely closed when the idle revolution number is feedback-controlled by controlling the flow-rate of the intake air which detours around the throttle valve. CONSTITUTION:An idle revolution-speed controlling valve 26 is installed in a by-pass 24 which is installed so as to detour a throttle valve 18 in an intake passage, and is controlled, in idle operation, by a digital control circuit 54 according to the difference between the engine revolution number which is obtained from the output of a crank angle sensor 44 and the aimed idle revolution number. If the reduction speed of the engine revolution number becomes over a prescribed value and the idle air correction amount which is obtained according to said reduction speed becomes larger than the preceding value, when the throttle valve 18 is completely closed, the control circuit 54 corrects to increase the amount of idle air. After the above increase is corrected, the engine is controlled slowly in a prescribed deceleration speed.

Filed: 1988-05-11
Abstract: PURPOSE:To suppress the infiltration and diffusion of water and to lower the dilution rate of samples by repeating the 2nd and subsequent sample sucking and dispensing operations while at least a part of the initially sucked dummy liquid is made to remain. CONSTITUTION:An air layer 12 filled with water 11 is previously interposed in a nozzle 3 and the dummy sample 13 is sucked therein. The sample 9A necessary for analysis of an item A is first sucked in this state and thereafter, the sample 9A is dispensed into a corresponding vessel 2a. The dummy sample 13 is then held intact and after the sample 9B necessary for analysis of an item B is sucked, the sample 9B is dispensed into a corresponding vessel 2b. The sucking and dispensing operations of the ensuing items are thereafter repeated in the same manner while the dummy sample 13 is held intact. The sucking and dispensing operations of the samples are repeated while the dummy liquid is held in the nozzle 3 if the operations are carried out in such a manner and, therefore, the infiltration and diffusion of the water are suppressed. The dilution rate of the samples is, therefore, lowered.

Title: Hydraulic power steering system having noise reducing means
Inventor: HARPOLE GEORGE M
IPC: B62D5/07
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic power steering system including a gear pump having a means for reducing noise caused by the fluctuation of pressure produced at the time of gear rotation. SOLUTION: A hydraulic power steering system includes a reservoir 14 for housing a hydraulic fluid 68, a gear pump 16 having a suction hole 74 and a hydraulic muffler 18.

The muffler 18 reduces noise by suppressing the fluctuation of the rate of a flow generated by the meshing gear 80. The muffler 18 includes a compliant element 92 and a fluid inertial structure 92 arranged between the suction hole 74 and the fluid 68 in the reservoir 14. The inertial structure 90 responds to the fluctuation of a flow rate by directing corresponding liquid pressure fluctuation so as to deform the compliant element 92. Thus, noise are reduced at the time of deformation of the compliant element 92.

Title: Particle detector
Inventor: TOMIKAWA KAZUYA
IPC: G01N15/14
Filed: 1991-05-20
Abstract: PURPOSE:To enable the number of particles when the particle density is large to be measured accurately by connecting a photoelectric conversion output in cascade and then inputting it to a plurality of particle detection circuits where a final stage is connected to an initial stage and further inputting these outputs to a particle detection control circuit in parallel. CONSTITUTION:When a signal from a photoelectric conversion means 12 is input to an only circuit 211 which is in operation state among particle detection circuits 211-21n, the circuit 211 stores a peak voltage value which is obtained by measuring an instantaneous value of the signal at a specified time interval into a memory. The circuit 211 continues to perform measurement after this, generates a trigger signal when the signal is reduced to a specified reference voltage, and inputs it to a next-stage circuit 212, thus preparing for a signal which enters next as an operation state. After the circuit 211 outputs the peak value within the memory to a particle detection control circuit 22, it continues a non-operation state until a trigger signal enters from the circuit 21n, thus enabling electrical signals which are outputted at extremely close timings to be treated separately by the circuits 211-21i and the circuit 22 to measure the number of particles accurately.
