Abstract: PURPOSE:To speed up an arithmetic operation by composing a multiplying circuit concerned so that input data can be multiplied in parallel first, next, the result data can be shift-processed and an arithmetic calculation can be executed when a necessary data accuracy is low at the 1/2 of a data size maximum value or below. CONSTITUTION:By a multiplying circuit 8, the data for respective halves of the high-order bit side and low-order bit side of the input data are considered as the respectively independent data, the respective multiplications are executed in four systems in parallel by multipliers 26-29, a shift processing or 0 set processing is executed by shifts 30-33n for respective result data, and next, an addition or subtraction processing is executed by arithmetic computing elements 39-40 for the result data. Namely, the calculations in plural systems are executed with the same hardware at the double speed or above. Thus, in the case where the data accuracy is sufficient at the 1/2 of the data size maximum value or below, even the necessary calculation quantity can be suppressed down to 1/2 or below, and the high-speed calculation can be executed.

Title: Driving system for write element of print head
Inventor: KIKUNO MITSUTOYO
IPC: B41J2/455
Filed: 1990-01-08
Abstract: PURPOSE:To ensure stable, high multi-density gradation recording quality against irregularities in the writing volume of data using write elements by controlling an energization time for write elements in accordance with an output signal from logic sum circuits and thereby expressing the density gradation of each write pixel. CONSTITUTION:Correction data from a correction memory unit M1 and a digital image signal consisting of bits for each pixel are added using an addition circuit ADD and thereby the irregularities of write elements are corrected. An 'n' bit image signal from this addition circuit ADD is converted to a 2<n> bit image signal, and the input of an image signal from a decoder DC to shift registers S1 is controlled by gate circuits Ca to Ce, Dg1 to Ggn, Gh1 to Ghn, Gi1 to Gin. Then the logic sum of each output signal from the shift registers Si is obtained by each one of logic sum circuits. Thus the energization time of each write element is controlled using output signals from logic sum circuits and the density gradation of each write pixel is indicated.

Filed: 1980-01-10
Abstract: PURPOSE:To make it possible to connect lines without requiring a control information line by start of a slave station or a master station, by providing plural receivers, a repeater, a priority setting equipment, and plural relays. CONSTITUTION:When data is transmitted through the first line A2 from a slave station, for example, P2, receiver REC2 detects the start signal, and relay T2 is operated by the control output of REC2. Then, change-over switch t2<0> is switched to connect line A2 to the second line B through repeater 12. Since priority set switch t2<3> is switched also, succeeding lines are held until data transfer dependent upon the first line A2 is completed; and after completion of this data transfer, succeeding lines are switched and connected. For data transfer from master station Q to slave station, for example, Pn, the slave station designation signal coming through the second line B and repeater 12 is detected by selector 13 to operate corresponding relay Tn, and as a result, switch tn<0> is operated to connect the second line B to the first line A through repeater 12.

Abstract: PURPOSE: To obtain a simple cyan biosensor adaptable even when measuring concn. is low by combining a carrier on which Pseudomonas fluorescence NCIMB 11764 is immobilized with an oxygen electrode. CONSTITUTION: Bacteria is immobilized on a nitrocellulose membrane 123 having Pseudomonas fluorescence NCIMB 11764 immobilized thereon. At the same time, an electrolyte 121d is introduced into an oxygen electrode 121 to assemble a cyan biosensor 12 which is, in turn, arranged in a thermostatic tank 14 and the electrode 121 is connected to a power supply and a buffer soln. is introduced into a tank 14 from an introducing port. A voltage ammeter 18 is monitored and, after a current value is stabilized, a cyan-containing sample soln. is guided into the tank 14 in the same way. The sample soln. passes through the gap between the sensor 12 and the bottom wall of an outside cylinder tank 16 and a dialytic membrane 127 to come into contact with the membrane 123 having bacteria immobilized thereon. Cyan is biologically decomposed by bacteria and the dissolved oxygen in the sample soln. lowers and the current value of the ammeter 18 is reduced. Since this current change quantity relies on the concn. of cyan, the concn. of cyan can be measured from a already formed calibration curve.

Title: Hydraulic motor driving circuit
Inventor: ONDA KIMIMASA
IPC: F03C1/24
Filed: 1995-01-11
Abstract: PURPOSE: To improve a feeling in the stopping operation of a hydraulic motor by specifying relief valve set pressure to a predetermined fixed value in driving the hydraulic motor and to a variable value approximately in inverse proportion to the capacity of the hydraulic motor in the stoppage of the driving. CONSTITUTION: In operation of a motor controlling valve 6 for driving a hydraulic motor 4, motor driving pressure acts on relief valves 16, 18. Since the relief valves 16, 18 set pressure under such driving condition is specified to have a predetermined fixed value, the driving torque of the hydraulic motor 4 is ensured as before. On the other hand, when the drive of the hydraulic motor 4 is stopped and the motor controlling valve 6 is neutralized, motor capacity controlling pressure acts on the relief valves 16, 18. In the stopping operation, the pressure set by the relief valves 16, 18 is specified to have a variable value approximately in inverse proportion to the motor capacity.  Thus, braking torque is fixed irrespective of the motor capacity, so that an impact in the stopping operation of the hydraulic motor 4 from the low speed operation is mitigated to improve an operational feeling.

Abstract: PURPOSE:To reduce the fear to omit the texture (pattern) information by the selecting state of the (m) value in such a conventional case where an original density image is divided into the rectangular areas of (mXm) picture elements when the texture areas of a gradation image having plural textures are roughly divided, a single picture element is sampled at a prescribed position of the rectangular area for production of a reduced image which is further divided into smaller rectangular areas of (nXn) picture elements, and the density histograms of the adjacent smaller rectangular areas are compared with each other for integration or separation of these rectangular areas. CONSTITUTION:An average density value calculting part 3 calculates the average density value of (mXm) picture elements of a rectangular area of an original image. A reduced image is produced with use of the picture elements having the calculated average density value and via an image reducing part 4 and then stored in a storage part 5. Then the accumulated density histograms of the adjacent areas of (nXn) picture elements included in the reduced image are produced via a production/comparison part 6 and compared with each other. Thus these adjacent areas are integrated together or separated from each other, and the results of these integration and separation are stored in a storage part 7.

Abstract: PURPOSE:To prevent slip of wire rod to keep a wire speed constant by winding wire rod through a rotatable turn roller provided between an upper wire rod winding part and a lower one of a winder and sending out from a pressing roller to a winding frame. CONSTITUTION:A flange 2 is provided on the periphery of a winder 1 intermediate section in the axis direction to form an upper wire rod winding part 3 and a lower wire rod winding part 4.
