Title: Sensor picture processing method
Inventor: FURUMURA FUMINOBU
IPC: G06T1/00
Filed: 1987-11-11
Abstract: PURPOSE:To process a picture on a real time basis with a moving body mounted sensor by carrying out a processing to correct distortion with a picture processor, and storing the resulting corrected picture to mutually different picture memories. CONSTITUTION:The picture photographed by a sensor 1 is accumulated in a buffer 10. A picture processor 11 corrects the distortion based on position/ azimuth information 12 in the space of a sensor at the time of photographing the picture which is given from the outside and position/azimuth information 19 of a virtual sensor set in the space decided by the picture to be a reference, and the resulting corrected picture is stored in a picture memory 13. Plural memories 13 are prepared, and the pictures at different times are stored into the different memories. In such a method, since the correlation processing of the character point of the overlapping part of the adjoining picture is not carried out, the processing time can be shortened. Consequently, the moving body mounted sensor can present the highly resoluted picture in a wide visual field on a real time basis.

Title: Erasure current supply circuit for flying erasure head
Inventor: FUKUDA HIROSHI
IPC: G11B5/024
Filed: 1986-11-28
Abstract: PURPOSE:To maintain the constant erasure current of a flying erasure head by connecting a diode with the same temperature characteristic as that of a voltage between the base and emitter of a transistor (TR) between a resistance and the base of the output transistor. CONSTITUTION:The diode 10 having the same temperature characteristic as the voltage VBE between the base and emitter of the TR5 is connected between the resistance 3 and the base of the TR5. Where a voltage at a connection point between a power source terminal 4, the resistance 3 and the diode 10 is Vac and a voltage between both end of the diode 10 is Vf, Vab=Vac+Vf holds. Consequently the erasure current IF (Vab-VBE)/R=(Vac+Vf-VBE)/R holds. The Vf and the VBE have the same temperature characteristic, and their fluctuating amounts due to temperature are canceled. As a result, the erasure current IFE is not affected by temperature and becomes constant, thereby always conducting a satisfactory flying erasure.

Title: Method and device for detecting ground fault of distribution line
Inventor: KATO KATSUMI
IPC: H02H7/26
Filed: 1990-10-23
Abstract: PURPOSE:To detect a minute ground fault by finding the effective component of the zero-phase-sequence current in phase with the zero-phase-sequence voltage in each line, by judging that there has occurred a ground fault of the line when the change of its effective component exceeds a specified value, and by interrupting only the line. CONSTITUTION:The signal 22a of a sinusoidal zero-phase-sequence current I0 is transmitted to a phase comparing section 24 used as a phase difference measuring circuit. And its phase is compared with that of the signal (reference signal) of a rectangular zero-phase-sequence voltage V0. This extracts its effective component In to the signal (reference signal) of the zero-phase-sequence voltage V0. Next a peak holding circuit 28 extracts the peak and an impulse response is obtained after the passage through a high-pass filter 29. When the change of this impulse response is large, the abnormality is judged to be minute ground fault.

Title: Device for recording and reproducing disk and method therefor
Inventor: TAJIRI TAKASHI
IPC: G11B7/004
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To quickly discriminate the kind of a disk. SOLUTION: Whether a disk set in the device is a CD or a DVD is discriminated by a CD discriminating sensor, and whether a DVD is an SL(single layer) disk or a DL(dual layer) disk is judged from reflectance of the disk. When the SL is judged first, but if this is wrong, provided that discrimination between the DL disk and the SL disk is not so reliable, discrimination at least between the DVD and the CD is low probability of making an error. Therefore, in this case, probability of the DVD is considered to be higher than probability of the CD, and the DL disk of the DVD is discriminated. Then, even when the DL disk is not discriminated, the CD is finally discriminated.

Filed: 1990-10-22
Abstract: PURPOSE:To contrive the improvement of weatherability and durability by forming a pattern printed layer on a releasable transfer mount paper by using the ink containing a specific mixture as a vehicle. CONSTITUTION:A pattern printed layer 2 is formed on a transfer mount paper 1 having a releasing ability such as plastic film by using the ink containing as a vehicle acrylic resin or a mixture of acrylic resin and a vinyl chloride-vinyl acetate copolymer or fluororesin or mixture of fluororesin and acrylic resin. A solid printed layer 3 is further formed on the pattern printed layer 2 by using a colored ink containing the same vehicle as in the pattern printing, when it is desired to hide the ground of the material to be transferred or there is concern that the transfer mount paper may contact the aforesaid material at the time of transfer. To improve the peeling-off ability between the pattern printed layer 2 and the transfer mount paper 1, an acrylic resin separating agent layer 4 is provided therebetween. This method also affords a protective layer for the pattern printed layer after transfer to improve weatherability.

Filed: 1986-11-28
Abstract: PURPOSE:To obtain the optimum residual signal even in the joint of frames in the voice encoding device using a block floating process by detecting the maximum value of the data in a former frame and an input signal in a current frame to give to a maximum value correction circuit and normalizing an original signal value in the maximum value correction circuit to update the data of an estimated filter. CONSTITUTION:If the data which remains in the estimated filter 2 is the last data of the former frame, the maximum value correction circuit 4 restores the data to the original signal value from the value normalized with the maximum value of the input signal of the former frame and gives it to a block floating process part 1. The block floating process part 1 where it is received detects the maximum value of the data in the former frame and the input signal in the current frame and gives it to the maximum value correction circuit 4. By means of the maximum value the maximum value correction circuit 4 converts the original signal of the residual data into the normalized value and gives it to the estimated filter 2 so as to update the normalized value data of the estimated filter 2.

Filed: 1986-11-29
Abstract: PURPOSE:To prevent the powdery image formed on a recording member from being scattered toward the picture display part by providing a sheet-shaped transparent conductive member, which is connected to the same potential as the conductive layer of the recording member, between the picture display part and the image forming face of the recording member. CONSTITUTION:A transparent conductive sheet 61 is arranged between a display window 49 and a recording belt 27 in a picture display part 25. The sheet 61 is connected to the same earth potential as the conductive layer of the belt 27. Thus, the toner image formed on the surface of the belt 27 is prevented from being scattered toward the inside of the display window 49 by static electricity caused in the display window 49. Even if the toner image is scattered, the display window 49 is not dirtied because a conductive toner 35 is stuck to the surface of the sheet 61.
