Title: Pcm signal recording and reproducing device
Inventor: YAMAZAKI SHIGERU
IPC: G11B5/09
Filed: 1985-12-09
Abstract: PURPOSE:To remove a DC component caused by a small-sized capacitor and to attain the miniaturization and simplification of a circuit by superimposing other signals in a no signal area where an intermettently generated recording signal lies. CONSTITUTION:A signal processing circuit 8 applying the prescribed processing such as adding a correction code to a digital signal inputted from a terminal 14 is operated by the clock of a reference clock generator circuit 9, and the timing for generating the recording signal is given by a generation pulse TACH whenever a fixed cylinder 2 makes a turn. Receiving the pulse TACH, a main processing circuit 10 executes each signal processing, and transmits a PCM signal to an initial 90 deg. range during each head period. At that time, a frequency dividing circuit 11 generates a 4.7mHz signal obtained by dividing a clock of 9.408mHz used in the circuit 10 into two, for instance. With the aid of a gate signal generated by the circuit 10 a gate 12 controls the 4.7mHz signal, and transmits the PCM signal to an OR circuit 13 while the circuit 10 does not output the PCM signal. The circuit 13 obtains a signal obtained by adding the 4.7mHz signal to the PCM signal. Thus the capacities of DC blocking joint capacitors 51 and 52 can be reduced.

Title: Detecting method for defect of insulated wire
Inventor: TADA HIROYUKI
IPC: G01B7/00
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which the abnormality of a conductor part can be detected by a method wherein outputs of one pair of conductor electric-field sensors which are installed in symmetric position in the circumferential direction of an insulated wire are corrected by outputs of one pair of external magnetic-field sensors which are installed on their symmetric line and the outputs are compared with each other. SOLUTION: Two conductor magnetic field sensors 11 of an identical type are installed in separated symmetric positions in the circunferential direction of an insulated wire 1, and a magnetic field ϕa which is generated at a time when an alternating current is made to flow to the insulated wire 1 is detected. In addition, two external magnetic-field sensors 12 of an identical type are installed on the symmetric line C of the conductor magnetic-field sensors 11 in such a way that a detecting axial line is matched with the symmetric line C, and an external magnetic field ϕb is detected.  Detection values of the conductor magnetic- field sensors 11 are corrected by detection values of the external magnetic-field sensors 12, and the existence of an abnormality such as a strand disconnection or the like in a conductor part 2 is discriminated on the basis of whether a difference is generated between the detection values of the two conductor magnetic-field sensors or not. By this method, it is possible to obtain a detecting method whose detecting range is expanded and whose detecting efficiency can be enhanced.

Title: Recording paper of thermal transfer printer
Inventor: HIRANO SEIICHI
IPC: B41M5/52
Filed: 1988-10-31
Abstract: PURPOSE:To prevent the deterioration of recording quality by making the shape ununiformity of a transferred pixel inconspicuous by providing a transparent layer sufficiently thicker than the transfer thickness of heat-meltable ink to the surface of recording paper on the transfer side thereof. CONSTITUTION:A transparent layer 1b is provided to the surface of recording paper 1 on the transfer side thereof and the thickness of said transparent layer 1b is made larger than the total thickness of heat-meltable ink 2 transferred in surface sequence. Since this recording paper 1 has the transparent layer 1b on the surface thereof, a part of the light transmitted through the ink 2 transferred to the surface of the recording paper 1 is not reflected from the surface of the recording paper 1 and transmits through the transparent layer 1b to be reflected from the interface of the transparent layer 1b and the base material 1a of the recording paper 1. That is, the pixel transferred to the surface of the recording paper 1 is overlapped with the projection image 3 formed at the interface of the transparent layer and the base material of the recording paper and, since the projection image is lower in density than an actual pixel and has a wide area and is blurred in its contour, the shape of the transferred pixel is inconspicuous even if ununiform, resulting in that recording quality is not deteriorated.

Abstract: PURPOSE:To shorten working time by tilting the edges of tools in opposite tool posts in the same direction, shifting the edges by the same amount in the same direction relative to the center of a workpiece, and cutting the long workpiece by a NC lathe from both directions to machine it while keeping balance without producing chattering. CONSTITUTION:When a long workpiece 4 is cut, a tool 7 of an upper tool post is fixed into a turret reversely to the workpiece 4 for cutting it simultaneously by both the tool 7 and a tool 11 of a lower tool post. The edges of the tool 7 and the tool 11 are shifted upward by the same amount relative to the center of the workpiece. A depth of cut is given to the workpiece in the X axis and the workpiece is cut with concurrency control by a NC.

Title: Frame synchronizing circuit
Inventor: ICHIBAGASE HIROSHI
IPC: H04J3/02
Filed: 1990-10-15
Abstract: PURPOSE:To separate a high speed multiplex code series even when the number of separated lines increases and to attain frame synchronization by adopting multi-stage configuration for a frequency divider counter and a line separating circuit, and converting a shift pulse width at the time of setting up frame synchronization into one bit width of an upper-stage counter operation clock to shift the counter of a 1st stage. CONSTITUTION:When an output series nXm data is not expanded in parallel in a prescribed order, a frame synchronization section 17 detecting it generates a number to be shifted in the number of pulse. Since the frame synchronization section 17 is operated at a 2nd frequency division clock, the width of the shift pulse is a 1-bit width of the 2nd frequency division clock. The shift pulse is converted into a 1-bit width of the 1st frequency division clock by a shift pulse width conversion circuit 18 comprising, e.g. an AND gate 19, the phase of the 1st frequency division clock being the output of a frequency division counter 12 is shifted to a prescribed position, the phase of the 2nd frequency division clock is changed based thereon, and an nXm series output data is obtained at a desired location. Thus even when the number of separated lines is increased, a high speed multiplex code series is separated.

Title: Image reader
Inventor: OTANI MIYUKI
IPC: H04N1/40
Filed: 1989-10-25
Abstract: PURPOSE:To simply execute gamma correction without requiring a long time by using the range and inclination of data approximated by a polygonal line for a data table as a format for inputting gamma curve data. CONSTITUTION:In the shown graph, A to G are the inclination of respective linear expressions and (a) to (g) are the range data of respective polygonal lines. Since the gamma curve is approximated by the polygonal lines and the inclinations and ranges of respective straight lines are used as information, down-loading can be attained by the volume of data less than that used for sending gamma correcting data as the data table. Consequently, the processing time can be remarkably reduced as compared with the processing of information approximated to a high-dimensional expression.
