Abstract: An automatic centering method for a video camera having a plurality of pick-up tubes and a deflection control circuit for each of the plurality of pick-up tubes is disclosed, which includes the steps of comparing outputs of two pick-up tubes of the plurality of pick-up tubes to thereby generate an error signal, processing the error signal to thereby generate a control signal, supplying the control signal to the deflection control circuit for one of the two pick-up tubes, storing the control signal in a memory, changing the control signal supplied to the deflection control circuit by a predetermined amount, repeating the above-described first to third steps, comparing the control signal generated in the sixth step and the control signal in the memory with each other to thereby generate an error flag signal when the above two control signals do not coincide with each other and indicating the error flag signal.
Abstract: A cassette tape recording and/or reproducing apparatus has a pair of movable reel tables, the center distance between which is automatically so adjustable as to coincide with the center distance between the reels of any tape cassette optionally selected from various types of tape cassettes.
Abstract: An apparatus for recording and/or reproducing digital information signal with sampling frequencies fs1, fs2, fs3, --- fsn comprising circuit for selecting one of the sampling frequency, and circuit for generating a field clock having a field frequency F determined by a following equation;fs1/N1=fs2/N2=fs3/N3=--- =fsn/Nn=Fwherein N1, N2, N3, ---Nn are the number of data words in one field.
Abstract: A double-layer coil for an electric motor is formed of a single continuous conductor with the two layers being wound simultaneously. A first length of conductor is wound about a pulley to form a coil and at the end of that coil but without breaking the conductor another coil is commenced to be wound about a rotating bobbin, with the coil of the first length wound on the pulley being caused to orbit the bobbin at a rate twice the bobbin rotation speed, whereby the conductor coil is unwound from the pulley and rewound on the bobbin at and the same time a further conductor is being wound about the bobbin to form a second coil, thereby forming both layers of the coil simultaneously.
Abstract: A charge-coupled device (CCD) camera with a smear reducer circuit is disclosed, which includes a CCD for generating a pickup signal, a memory for storing an extracted smear signal from the pickup signal and, a level selector circuit for cutting off a noise contained in the smear signal with level less than a predetermined level in the smear signals from the memory. The output of this level selector circuit is subtracted from the pickup signal to thereby obtain a pickup signal with the smear reduced as well as a noise component suppressed.
Abstract: A memory card includes a card support formed by two plastic boards; a printed circuit board mounted on the card support; an integrated circuit mounted on the printed circuit board and including a memory for storing information, a central processing unit for accessing the information, and access terminals connected to the memory and central processing unit for accessing the information from the memory; a plurality of connection terminals provided on an exposed surface of the printed circuit board; a common ground discharge pattern provided on the exposed surface of the printed circuit board and separated from the connection terminals by first discharge gaps; a plurality of lead terminals provided on a non-exposed surface of the printed circuit board and connected between respective ones of the connection terminals and respective ones of the access terminals of the integrated circuit; a second discharge pattern formed on the non-exposed surface and separated from the lead terminals by second discharge gaps such
Abstract: In a channel selecting apparatus for a television receiver having an electronic tuning tuner for changing the receiving frequency in accordance with an analog control signal applied thereto; a memory has a plurality of addresses for storing respective digital codes each identifying a respective channel and which are selectively activated so as to effect read out of the respective channel identifying digital code to a digital-to-analog converter which converts the same into a respective analog control signal for the tuner. A deviation of the receiving frequency, as established in response to the analog control signal, from the correct receiving frequency for the channel identified by the digital code then being read out of the memory is detected, and, in response to a detected deviation within a pull-in range of an automatic fine tuning (AFT) circuit, the latter changes the digital code applied to the converter in the sense for removing such deviation and thereby achieving the correct tuned condition.
Abstract: The invention relates to a process permitting the dissolving of the skin or hide and the recovery of the hair.After rehydrating and scouring the skins or hides are plumped and predegraded at an alkaline pH and then dissolved by enzymatic action. The hair obtained is in a satisfactory condition and can be subsequently utilized.
