IPC: G01B7/00
Filed: 1984-04-27
Abstract: PURPOSE:To achieve the quality control for uneven thickness of a sheet material and higher yields thereof by arranging a ball made of a magnetic metal on one side of the surface of an object to be measured in the thickness while a magnetic core and a magnetic detector are arranged on the opposite side thereof to measure the online thickness of the running sheet. CONSTITUTION:A magnetic metal ball 7 is arranged on one side of the surface of a sheet material 2 as object to be measured in the thickness while a magnetic core 6, an AC power source 4, a magnetic detection coil 5 which detects changes in a magnetic field excited with a magnetic coil 3 and an electronic circuit 8 which amplifies and computes changes in the output voltage 14 of the coil 5. In this case, in place of the coil 5, one or a plurality of magnetic sensors 9 may be used. To achieve a fine contact with a thick body 2, a rotary space 12 is interposed between the magnetic core 6 and the sheet material 2. When measuring the sheet material 2, the metal ball is attracted by the magnetic core 6 to increase the adhesivity with the sheet material 2 through a freely rotary fine contact. As the thickness of the sheet material 2 varies, the magnetic field changes, causing a change in the output pressure of the coil 5. The output voltage 14 is amplified and computed with the circuit 8 to measure the thickness of the sheet material 2.

Title: Privacy circuit
Inventor: FUJISAKI HISASHI
IPC: H04K1/00
Filed: 1978-07-11
Abstract: PURPOSE:To realize a simple and mineature structure for the circuit and unit as well as the quick alteration of the types of the private talk by using the transmission-side privacy circuit incorporating the delta modulator and demodulator plus the digital circuit and the reception-side privacy reproduction circuit. CONSTITUTION:Delta modulator 109 converts aural signal (a) supplied into binary pulse row signal (b). Divider circuit 110 regards the supplied signal (b) as (a) polynomial on the Galois substance and then divides it by the known polynomial to which only the coefficient is specified optionally to obtain the quotient. Pulse row signal (e) given from circuit 110 is suplied to delta demodulator 11 to be converted into analog signal (f). Signal (f) is then demodulated by the radio receiver to be changed into analog signal (g) and then to be supplied to delta modulator 209. Signal (h) which converted signal (g) into the binary pulse row is delivered from modulator 209 and then supplied to multiplier circuit 210. Here a multiplication which is exactly same as the polynomial of circuit 110 is carried out. Thus pulse row signal (k) delivered from circuit 210 is supplied to delta demodulator 211, and analog signal is delivered. Signal is the same as signal (a) transmitted.
