Filed: 1995-01-27
Abstract: PURPOSE: To provide a chuck mechanism for both ends cutting devices, which is capable of rotating in state where a work is clamped so that it can be cut, and of clamping the work easily in a single operation. CONSTITUTION: A chuck mechanism is mainly formed of a rotational body 3 having a hollow part into which a columnar work 4 is inserted, and a fixing body 2 for rotatably supporting the rotational body 3. The work 4 is inserted into the hollow part of the rotational body 3 in state where the work 4 is protruded from both ends of the hollow part, that is, so that both end faces of the work 4 can be cut. When air cylinders 13 are operated, bearings 15 push the inclined faces 11a of lever-type claws 11 to rotate them lever-type claws 11 around spindles 12 to push movable sleeves 9 against fixed sleeves 8. Between both the sleeves, ring-like elastic bodies 10 are interposed, and when the sleeves 9 are pushed, the elastic bodies 10 swell to hold and clamp the work 4.  The rotational body 3 is rotated through a pulley 6, and a belt 7 in order for both ends of the work 4 to be cut by cutting tools 30.

Inventor: YAMASHITA TOMIO
IPC: G06F3/12
Filed: 1994-02-03
Abstract: PURPOSE:To validate synchronizing signal pulse width at every host or corresponding to an application and to improve noise resistance. CONSTITUTION:A transmission part 51 is constituted of a circuit including a driver for signal output and a pull-up resistance. A reception part 52 receives a signal transmitted from the transmission part 51. A signal width detection block 53 detects only a signal having width larger than a value which is set as an effective signal. In the signal width detection block 53, printer CPU which is not illustrated sets the width of a signal for detection in a signal width setting part 53a as the effective signal through a data bus. A signal detection part 53b detects the signal width of the inputted signal. A comparison part 53c compares a value which is set in the signal width setting part 53a with that detected in the signal detection part 53b. When inputted signal width is larger than the setting value, the input signal is outputted as a significant signal.

Title: Method for converting image data of dot image
Inventor: NAKA HIDEKI
IPC: H04N1/405
Filed: 1989-01-20
Abstract: PURPOSE:To prevent moire occurring even when a dot image is reproduced by converting the image data of an original image that is the dot image to new image data by applying position interpolation on the mean value of the image data at every picture element block. CONSTITUTION:The image data D0 read by an input scanner 1 is preserved in the memory 23 of an image processing device 2. The device 2 divides and sets the inside of the original image into plural picture element blocks consisting of picture elements of 3X3. Next, part of the data D0 preserved in the memory 23 i.e., the image data of partial image is read out, and is stored in a buffer memory 12. Following that, an arithmetic circuit 22 calculates the mean value of each picture element block based on the image data of the partial image. The new data of peripheral picture element of the picture element block can be found by applying weighted mean by multiplying the mean value of the picture element block and that of a neighboring picture element block by coefficients (m) and (1-m), respectively.

Title: Recording and reproducing device of signal
Inventor: KOUZUKI SUSUMU
IPC: G11B5/588
Filed: 1983-01-27
Abstract: PURPOSE:To attain optimum tracking at the time of reproducing in a device writing data doubly on adjacent tracks by two heads with different head width each other by supplying pilot signals to the two heads to use the reproduced pilot signals and head width information. CONSTITUTION:Reproducing is performed from the shown recording track as follows. When a reproducing video signal is inputted from a terminal 17, respective pilot signals f1-f4 are added to an adder 22. On the other hand, the output of a BPF18 is detected at its envelope and compared with reference voltage (e) by a comparator 24 to discriminates whether a signal f1 is included in a recorded field or not. Consequently, the phase of a four-phase pulse is reset every time when the signal f1 is reproduced. Namely, a signal having always the same frequency as that of a pilot signal of a reproducing track reproducing a video signal is applied to a frequency converter 27 as a local signal and frequency components of 10kHz and 30kHz are extracted from the frequency-converted signal by BPFs 28, 29 and detected by envelope detecting circuits 30, 31. Output signals from the circuits 30, 31 are supplied to a control signal generating circuit 32, which outputs an autotracking controlling signal.

Filed: 1990-01-22
Abstract: PURPOSE: To reduce choking of an air stream in a hub region of a fan by forming a spinner as an axially symmetrical body for a rotary axis, attaching its downstream end to an upstream end of a hub, and flaring it just before air flows over an inner region in the radial direction of the arrangement of a moving blade. CONSTITUTION: A spinner 25 has an upstream end 27 and a downstream end 28 for a stream of air passing a suction part 22, is attached to an upstream end of a fan hub 26, and has a substantially elliptic cross section from a point A in the upstream to a position B past an intermediate point slightly, and an elliptic long axis is a rotary axis of the spinner 25. The downstream end 28 is flared outward in the radial direction like a trumpet.  For this reason, after a thickness of a boundary layer of air which flows above the spinner 25 and is accelerated in the axial direction due to the elliptic cross sectional shape is reduced, a speed in the axial direction of a local part of the air flowing above the spinner 25 is reduced to such extent that is sufficient for reducing or removing the occurrence of choking of the air in an inner region in the radial direction of a fan moving blade 12a before the air flows above the inner region in the axial direction thereof.

IPC: G01N29/06
Filed: 1983-01-31
Abstract: PURPOSE:To improve an S/N ratio by receiving repeatedly and converting a reflected wave into a digital signal and calculating the sum. CONSTITUTION:Pulses generated by a pulse generator 5 are passed through a switch 4 and radiated by transmitting oscillators 1-3. The reflected wave is received by a receiver 6 and converted by an AD converter 8 into a parallel digital signal, which is inputted to an adder 9. The output of the adder 9 is applied through a gate 10 to a receiving integration memory 11 consisting of a shift register and its output is applied to the other input of the adder 9. Then, wave transmission and reception are repeated on the same condition and waveforms are integrated in the receiving integration memory 1 until the amplitude of the reflected wave exceeds the amplitude of a noise. Transmitters 1, 2, and 3 are changed over and integral results are written in receiving memories 12, 13, and 14 respectively. Data of the receiving memories 12, 13, and 14 are summed up by adders 17 and 18, whose results are further added to an old picture in a picture memory 23 by an adder 21, whose output is written in a picture memory 23.

Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To use a small and light electrical pump for a low pressure pump without causing shortage of discharge quantity so as to reduce electricity consumption and costs by providing a controlling means for lowering an upper limit value of the number of revolutions of an internal combustion engine when a supply voltage for the low pressure pump is lowered below a predetermined level. SOLUTION: In starting an internal combustion engine, an ECU 8 determines whether a fuel pressure inside a high pressure fuel pipeline 18 reaches a normal high fuel pressure value or not on the basis of a sensor signal from a fuel pressure sensor 34. If a determined result is YES, it is determined whether a supply voltage of a low pressure pump 4 is lowered below a normal level by not less than a predetermined value or not. If the supply voltage is lowered below the normal level, the number of engine revolutions is maintained at an upper limit in a normal time.  If a discharge quantity of the low pressure pump 4 is lowered according to a drop of the supply voltage, the upper limit of the number of engine revolutions is lowered to about 3000 rpm, for example, and then, a step, in which it is determined whether a fuel pressure reaches a normal high fuel pressure or not, and the next steps are carried out repeatedly.
