Abstract: PURPOSE:To execute subordinate synchronizing broadcast by providing a means superimposing a pilot signal, the generating means of a reference signal and a means adjusting transmission frequency so as to allow each broadcast station to use an existing program transmission line as it is. CONSTITUTION:Pilot signals PA, PB are extracted via BPFs 23, 24 in transmission stations B1, B2 and a reference signal Sref is generated from the signal by a subtractor 25. The next signal Sref is sent to a phase comparator 26 and frequency shift is applied so that the frequency of the pilot signal PC obtained by the BPF 47 is made coincident with the frequency of the signal Sref. Moreover, the signal Sref is fed to a phase comparator 28 and the oscillating frequency of a transmission carrier signal oscillator 21 is controlled so that the frequency division signal of the transmission carrier signal is made coincident with the signal Sref. Since the transmission stations B1, B2 apply the same operation, they are synchronized subordinately with the oscillator 123 generating a superimposed signal PC at the broadcast station A. Thus, the carrier frequency of both transmission stations is made coincident and the subordinate synchronizing broadcast is applied by using the existing transmission line.

Title: Temperature detecting circuit
Inventor: IWAMOTO MITSUMASA
IPC: G01K7/00
Filed: 1978-04-07
Abstract: PURPOSE:To improve the performance of an integrated temperature detecting circuit by making a reference power source of complementary type FETs and by using the difference between the threshold values of the FETs. CONSTITUTION:A bias circuit for determining a reference voltage is constructed to include FETs 211 and 212 of P and N channels having an equal value of beta, and a resistor 217. On the other hand, if FETs 213 and 214 of P and N channels have an equal value of beta, and if resistors 215 and 216 have an equal resistance, the output potential Vo at a terminal 218 is expressed by Equation - 1. As a result, since the potential Vo is given as the difference between the threshold voltage values of the FETs of P and N channels, the temperature characteristics of the voltage difference are used to detect the temperature. Moreover, since the voltage Vo is not dependent upon the supply voltage but uses the difference between the threshold voltages, the fluctuations not only between the elements but also between the resistances can be eliminated so that the performance of the integrated detecting circuit can be improved.

Title: Laminated plate
Inventor: NODA MASAYUKI
IPC: B32B27/04
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To lessen a warping by laminating layers of plural pieces of aramid fiber unwoven fabric base material in such a manner that the front and the back faces and the base material directions of the base materials are arranged in the same order. SOLUTION: An aramid fiber unwoven base material is manufactured by making paraaramid fiber chops and mutually binding fibers which form an unwoven fabric with a resin binder. Further, the unwoven fabric base material is impregnated with a thermoset resin and dried into prepregs and two or more pieces of the prepreg cut to the specified size are stacked and thermally molded under pressure into a laminated plate. In this case, the prepregs are laminated by arranging the front and the back faces and the base material directions of the aramid fiber unwoven fabric base materials in the same order. When the base material constituting the laminated plate is not totally the aramid fiber unwoven fabric base material, all the front and the back faces and the base material directions of the aramid fiber unwoven fabric base materials used are arranged in the same order.  Thus it is possible to lessen the warping of the laminated plate and ensure the minimization of the warping by arranging the base material directions of the base materials in the same order with regard to their front to rear directions.
