IPC: G10H1/057
Filed: 1988-04-26
Abstract: PURPOSE:To change the shape of the envelope of an output signal and to expand the application range of the above circuit by providing plural resistors and switches to a time constant circuit and selectively switching the time constant by the resistors and switches. CONSTITUTION:A low level is attained when an envelope switching control signal VC2 is selected by an envelope signal memory circuit 1. An FET Q22 is then turned on and the resistor R2 is connected in parallel to a capacitor C1. The time constant between terminals T1 and T2 is determined and the capacitor C1 is charged during this time and is discharged via the resistor R2. The low level is attained when an envelope switching signal VC3 is selected. An FET Q24 is then turned on and the resistor R3 is connected in parallel to the capacitor C1. The time constant between the terminals T1 and T2 is determined and the capacitor C1 is charged during this time and is discharged via the resistor R3. The amplitude changing scale signal V0 having the shape of the envelope varying with the time constant is thus obtd. and the application range is expanded.

Title: Conductor pattern protecting circuit of magnetic bubble memory element
Inventor: CHIBA SHINSAKU
IPC: G11C11/14
Filed: 1980-08-01
Abstract: PURPOSE:To completely protect a micropattern from disconnection even in case a pulse driver circuit has a faulty working which is caused when the power source of the driver circuit is switched on and off, by detecting the voltage and actuating a switching circuit. CONSTITUTION:A voltage detecting circuit 4 detects that the power source of a pulse driver circuit 2 that supplies the pulse current to a conductor pattern 1 gets out of a prescribed range. At the same time, a switching circuit 5 which is turned on and off by the signal of the circuit 4 is connected in series to the pattern 1. For instance, the level of the power supply voltage V2 of a gate circuit 7 in the circuit 2 is detected by a Zener diode 8, and the 2nd transistor 9 is turned on after the voltage V2 increases up to a level at which the output of the circuit 7 is fixed. Thus a pulse current Ip that flows in the time during which the output of the circuit 7 is not fixed can be discontinued.

CONSTITUTION:In a detecting pulse signal in case a particle suspension from a photodetector 31 passes through a fine detecting part, an amplitude of a pulse exceeding a threshold level by a noise threshold comparator 35 is processed by a pulse amplitude peak holding circuit 36, the first and the second comparators 41, 42, an AND circuit 43, an FF45, a counter 59, etc., and becomes a pulse amplitude digital value. This digital value becomes an address, a memory 60 is brought to access, and a frequency driven by an increment circuit 61 is witten. On the other hand, in the same way, the pulse width digital value becomes an address and the frequency is written in the memory 60. Subsequently, in accordance with a pulse amplitude frequency distribution and a pulse width frequency distribution which are based on two-dimensional contents of the memory 60, a computer 62 analyzes and determines the number of particles. According to this constitution which utilizes two kinds of frequency distributions, a particle discriminating accuracy of a particle counting device is improved, and also an abnormal particle can be detected.

Abstract: PURPOSE: To obtain a means ensuring the leaving of a wobble/noise(W/N) ratio as it is sufficiently high even when there is a positioning error for surely recovering information expressed by a differential signal. CONSTITUTION: A radiation source 10 generates radiation beams 11, and radiation beams are directed towards the servo track 4 of a rotating recording carrier 1 by an optical system. Beams reflected through the recording carrier are forwarded to a push-pull detector 12. The servo track is oscillated periodically in the radial direction, in which frequency is modulated by a positional information signal. A signal recovery circuit 17 recovers the positional information signal from a push-pull signal. Balance operation circuits 40, 41 or 50, 51 adapt a ratio during a range that a detecting signal contributes to a differential signal. A DC component in the adapted push-pull signal is obtained by a low-pass filter 44. A circuit 45 sets the ratio at a value, where the determined DC component substantially reaches zero, while depending upon the determined DC component.
