Filed: 1981-12-07
Abstract: PURPOSE:To prevent deterioration in S/N ratio and to reduce external disturbance by installing a distributor between a wide band amplifier and a frequency converting function part in a receiver of VTR which is used in combination with a TV receiver. CONSTITUTION:A signal from the input terminal 1 of a receiver of VTR is supplied through a wind-band amplifier 14 to a distributor 8, which separates an input signal; one output is passed through the frequency converting function part 17 which consists of a mixer 15 and an oscillator 16 and serves as part of a tuner function to obtain an intermediate frequency signal from an output terminal 9, and the signal is outputted to a recording system. The other output of the distributor 8 is led from an output terminal 12 to a TV receiver through a closed switch 11a of a two-way selection switch 10. During reproduction of VTR, a signal from a terminal 13 is outputted to the output terminal 12 through a closed switch 11b of the switch 10. The amplifier 14 eliminates deterioration in S/N ratio even when the signal is passed through the distributor 8 and the frequency converting function part 17 is connected to the distributor 8, so external disturbance is reduced.

Title: Thickness gauge
Inventor: INAGAKI SEIZOU
IPC: G01B15/02
Filed: 1982-11-12
Abstract: PURPOSE:To achieve a highly accurate computation of thickness regardless of inclination or vertical positional variation of an object to be measured by obtain inclination and average displacement thereof at the measuring position from displacement of several displacement meters provided on both sides of a thickness gauge to correct errors due to slant transmission of a measuring beam by the object to be measured. CONSTITUTION:An arithmetic processor 29 computes inclination and average displacement of an object 13 to be measured from displacements DELTAl1 and DELTAl2 on both sides of the measuring position and the distance D and sends a correction signal 30 for the slant measurement to an arithmetic processor 19 according to the inclination obtained while sending a signal 31 of the average displacement obtained to a memory 32. The arithmetic processor 19 performs correction for the slant measurement based on a thickness signal 18 and a correction signal 30 to obtain a thickness signal 33. This corrects errors due to the slant measurement in the thickness signal 33 outputted from the arithmetic processor 19 but leaves errors (pass line errors) due to average displacement as intact, still requiring due correction. To achieve this, a switch 35 is opened while a switch 36 closed with a controller 34. Under such a condition, the object 13 to be measured shall be a reference object with the known thickness.

IPC: G06F5/00
Filed: 1992-07-01
Abstract: PURPOSE:To shorten a data transmitting time, and to save a cost by transmitting pattern data through binary to hexadecimal conversion, at the time of transmitting data expressed by 0 and 1 to the other party by a character form. CONSTITUTION:Transmission data are, for example, 24 digit data, that is 24 bite data, and when the data are transmitted in the original form, 24X8 bit data amounts are obtained. At that time, the transmission data are divided into 8 digit units, and the divided 8 digits are divided into 4 digit units. Then, the data expressed by 0 and 1 of each 4 digit are converted from binary data into hexadecimal data, and converted into each 1 digit. That is, the 24 digit data are condensed into the 6 digit information. Thus, the binary pattern data expressed by 0 and 1 on transmission are hexadecimal converted, so that the number of digits of a bit can be decreased so as to be 1/4 times. Then, a step at a transmission side is inverse-transformed at a reception side, so that reception data can be decoded.
