Title: Delay circuit of power supply control signal
Inventor: OZAWA MASAHIKO
IPC: H03K17/22
Filed: 1983-11-29
Abstract: PURPOSE:To prevent malfunction of a switching circuit by setting the timing start point of a reset circuit for switching circuit at the final control signal regardless of continuation or discontinuation of the power supply control signal. CONSTITUTION:When a power supply control signal (a) is supplied to a transistor TR4, the TR4 goes to noconductive. Then the collector potential of the TR4 rises up, and the potential of a capacitor 29 rises up via resistors 26 and 28. When the potential of the capacitor 29 exceeds the constant potential of a constant voltage diode 30, a TR32 conducts and therefore the base input of a TR36 is cut off. Thus the collector side is opened, and a reset signal (c) is produced at the collector side of a TR22 in response to the conduction of a TR17. While the electric charge of the capacitor 29 is discharged via a diode 27 since the TR4 conducts in an OFF mode in case the signal (a) turns consecutively to ON, OFF and ON modes continuously. Then a detection circuit 24 is initialized. In such a way, a malfunction of a switching circuit 5 is prevented.

Title: Recording medium having ferromagnetic substance film
Inventor: MIZUKAMI ICHIRO
IPC: B42D15/10
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To detect authenticity of a substrate in use by writing a magnetic pattern in advance in magnetic films having alternately different magnetic characteristics or changing in thickness and sticking them as forgery preventing magnetic substance films on specific areas of the substrate. SOLUTION: An amorphous magnetic substance film capable of having magnetic singularity is stuck as the ferromagnetic substance films 3 and 4 on a previously arranged punch hole area or is buried. When a punch hole is bored in accordance with a residual measured service, magnetic changes take place in the films 3 and 4 respectively to enable the detection of a hole position. That is, the films 3 and 4 having different magnetic characteristics are arranged in a fixed periodical interval, and either of the films 3 and 4 should exist in an objective area on either the front surface or the back surface of the substrate 1. Then, since when a punch hole is bored, either or both of the films 2 and 4 should exist in that position of the hole, the hole can magnetically be detected out.  On the other hand, since there is the intrinsic magnetic pattern along a cross section, the forgery by a cutting and sticking method can also magnetically be detected out.

Filed: 1983-12-02
Abstract: PURPOSE:To reduce steady phase errors by controlling the characteristics of an LPF so that the DC gain is set at a finite level in a non-locked mode of a PLL and then increased after the PLL is locked. CONSTITUTION:A phase comparator 1 compares a horizontal synchronizing signal H-SYNC with a pulse obtained by shifting a horizontal pulse PH obtained from a flyback transformer 4 is a TV receiver through a 90 deg. shifting circuit 5. The phase error output obtained from the comparison is applied to a VCO3 via a lead lag filter 2 in the form of the control voltage. Both the horizontal synchronizing signal and the horizontal pulse undergo the phase comparison through a multiplier 6. Then a lock/non-lock detecting circuit 7 detects a locked or non- locked state of a PLL loop. For the characteristics of the filter 2, the DC gain has a finite and incomplete integration form in a non-locked mode of the PLL loop and then changed to an infinite and complete integration form in a locked mode respectively. This attains a quick lock-in action and reduces steady phase errors in a locked mode of the PLL loop.
