Title: Receiver for television signal
Inventor: ISOBE MITSUO
IPC: H04N5/455
Filed: 1986-07-15
Abstract: PURPOSE:To raise the stability of action, to improve an S/N and to reproduce the base band video signal of a high quality by providing a compensation filter for changing the amplitudefrequency characteristic of a digitized video signal. CONSTITUTION:An IF filter 41 wide band-processes the signal component of the objective channel in an IF signal which a tuner 3 outputs, and an adjacent and unobjective signal is removed. A characteristic compensation filter 61 which consists of symmetric transversal filters and the like can satisfactorily compensate a residual side wave band signal for the amplitude-frequency characteristic without the occurrence of a phase distortion. A local control circuit 21 for controlling a local oscillation frequency controls the characteristic compensation filter 61 through a conductor 22. With such a constitution, the total amplitude- frequency characteristic does not change with respect to a change in the local oscillation frequency, namely the change in the carrier frequency of an IF signal. That is, with setting the frequency of the characteristic compensation filter 61 to follow the change in the IF frequency, an almost constant characteristic can be maintained.

Title: Manufacture of abrasion resistant wire
Inventor: MIZUTANI YUKAKO
IPC: H01B13/06
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To restrict an insulation coat from entering into stranded wires, reduce adhesive property, and improve abrasion resistance by providing an air cooling area between a conductor softener and a coating extruder so that a conductor is below a specific temperature. SOLUTION: A conductor 2 passing through a dice 6 of a stranded wire machine and being a stranded wire is fed to a coating extruder 8 through a conductor softener 7. Next, while the conductor 2 passes through a cross head 8a of the extruder 8, a PVC (poly chloride vinyl) composition in a molten state is supplied around there, coated, and protruded, and an insulation coated body 3 is formed. A wire 1 thus coated is wound through a cooling layer 9. Here, the air cooling area is provided between the conductor softener 7 and the coating extruder 8 so that the conductor is below 70 deg.C. When the conductor 2 is thus air-cooled and the PVC composition is extruded and coated, intrusion of the insulation coat 3 into stranded wires of the conductor 2 is restricted, and adhesive force between the conductor 2 and the insulation coated body 3 is lowered.  Thus, even if a load is applied so as to cause friction with the insulation coated body 3, the load escapes, and abrasion resistance is improved.

Title: Image data processor
Inventor: MAEDA HIROSHI
IPC: H04N1/407
Filed: 1993-07-06
Abstract: PURPOSE:To remove unrequired data such as background or reversed printed characters by setting a threshold value corresponding to the deviation of image density. CONSTITUTION:A CCD part 3a performs the A/D conversion of an analog electric signal inputted from a CCD corresponding to each value of pixel density, performs MTF correction, white-and-black correction of gamma correction and outputs an 8-bit digital signal to a means value processing part 3b. Then, a density means value A of a low density gradation area, mean value C of high density area and mean value B of entire density are calculated. The mean value A shows the stain density of a picture and the means value C shows line drawing density. When a half tone such as a photograph or a picture is contained, however, the image is expressed by the entire gradation, and the values A, B and C are concentrated near the intermediate gradation. Therefore, it can be discriminated whether or not the original is written in line drawing, further, the threshold value is calculated corresponding to the result, a part smaller than this value is removed, and stain caused by the peak of deep background or reversed print, etc., can be removed.

Title: Digital broadcasting receiver
Inventor: TAKASHIMIZU SATOSHI
IPC: H04N5/45
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To easily and correctly arrange an antenna to face towards a satellite by generating a display signal, based on the measured result of an estimated error rate and setting the direction of the antenna into a direction where the error rate, indicated by means of the generated display signal, becomes smallest. SOLUTION: A control means 409 reads a value which indicates the estimated error rate from a comparing part 433. When the direction of the antenna is changed, the radio of the carrier and the noise (C/N ratio) of the received electric wave is changed, so that the estimated error rate obtained by the comparing part 433 is changed. The control means 409 controls OSD(on-screen display) after reading the estimation error rate, so as to display the value which indicates the estimated error rate in the screen of TV 410. Thus, it is recognized by what degree of C/N electric wave from the satellite is received at the time of arranging the antenna, so that the antenna is easily directed to the direction for which the C/N becomes most optimum, that is, the estimated error rate becomes smallest.

Title: Irradiance meter obeying cosine rule
Inventor: SUGA CHOICHI
IPC: G01J1/02
Filed: 1990-06-26
Abstract: PURPOSE:To make it possible to perform adjustment in conformity with a cosine rule by similarly illuminating the entire surface of the peripheral surface of a light diffusing plate with incident light which is cast on the incident surface of the light diffusing plate at an angle exceeding 0 degree (vertical) and less than 90 (horizontal). CONSTITUTION:The light which is cast through an incident light window 7 is diffused through a light diffusing plate 2a and guided into a light diffusing plate 2b. The diameter of the diffusing plate 2a is made smaller than the diameter of the incident window 7. Therefore, the slant incident light is cast through the front surface and the side surface of the diffusing plate 2a. The peripheral part of the incident window 7 becomes a light screening part, and the light other than the object to be measured exceeding a horizontal angle (90 degrees) is not cast in. Therefore, the amount of the incident light can be accurately corrected at the value that is approximate to the cosine rule. As a measuring instrument, it is necessary that the ratio between the diameters of the incident window 7 and the diffusing plate 2a is 0.8 or less. The diffusing plates 2a and 2b are arranged so that the directions where the light diffusing characteristics become the maximum values are intersected at a right angle. Therefore, even if the sensitivity of the slant incident light in the diffusing plate 2a is in short with respect to the cosine rule, the sensitivity of the slant incident light can be corrected in conformity with the cosine rule because the diffusing plate 2b generates the inverse action with respect to the diffusing plate 2a.

IPC: B41J2/345
Filed: 1989-06-28
Abstract: PURPOSE:To enable excellent printing without any white stripe to be obtained by a method wherein a length of a heating resistor line which is larger than a line feed pitch of a paper feed mechanism is provided. CONSTITUTION:A plurality of heating resistors 2A to 2J are linearly adjacently to each other arranged by providing specific intervals on a substrate 1. Further, in order to connect those heating resistors 2A to 2J to an outside, electrodes 3A to 3J are formed from edges of respective thermal resistors 2A to 2J to a peripheral side part of a bottom edge on the same substrate 1. Further, the other ends of respective thermal resistors are connected to a common electrode 4. A length of a line of those heating resistors is established in the width L+d which is larger by one dot content width than a line feedpitch L of a paper feed mechanism. In the case where dot like recording is performed by using a thermal head, though the more outer side it goes, the more easily the heat is discharged and a top and bottom parts of recording become thin in density, a problem of appearing a white stripe ds not generated since there is a one dot of overlapped part with one line feed between the top and bottom parts.
