Title: Fm stereo demodulating circuit
Inventor: ISHIDA KOUJI
IPC: H04H40/45
Filed: 1982-09-04
Abstract: PURPOSE:To prevent the generation of distortion, because no beat interference exists in signals to be demodulated on both left and right channels, by using a sinusoidal carrier wave not including an unnecessary harmonic component as a multiplication signal. CONSTITUTION:When a signal is outputted from a subcarrier signal generator 2 as a subcarrier signal, an operational amplifier 7 and a transistor (TR) Q9 in a current control circuit 8 act like a voltage follower and a signal is applied to a resistor R5, then the current flowing to the resistor R5, i.e., a current i1 flowing from a differential pair 3 to the current control circuit 8 is as shown in B when the stereo pilot signal has a waveform as shown in A. The circuit 8 is equivalent to a circuit where a constant current source I0 and a current source outputting a current changed depending on the sinusoidal subcarrier wave signal are connected in parallel. Similarly, a current control circuit 10 is equivalent to a circuit where a constant current source I0 and a current source outputting a current changed depending on the inverted signal of the sinusoidal subcarrier wave signal are connected in parallel, and the waveform of a current flowing from the differential pair 4 to the circuit 10 is shown by C in the figure.

Title: Pulse discharging circuit
Inventor: YOKOKURA KUNIO
IPC: H02M9/04
Filed: 1988-06-22
Abstract: PURPOSE:To make a high speed by attenuating the current about to flow via a charging reactor with a resistance connected in series to a discharging resistance, when a charging gap fails to operate. CONSTITUTION:A pulse discharging circuit connects in series a reactor 2, a charging capacitor 3, a charging reactor 4 and a resistance 8 across output terminals of a DC power source 1. In parallel to a series circuit of the charging reactor 3 and resistance 8 a commutation capacitor 6 and a discharging gap 7 are respectively connected in parallel. Furthermore, a thyratron 5 is connected between the reactor 2 side terminal of the charging capacitor 3 and one of the output terminals of the DC power source 1. Since the current flowing from the charging capacitor 3 through the thyratron 5 is thereby attenuated with the abovementioned resistance 8 when the discharge of the discharging gap fails, the energy of the charging capacitor 3 is consumed in a short time.

Title: Tap-controlled gas hot-water supplier
Inventor: YOKOAJIRO YOSHIYUKI
IPC: F24H9/20
Filed: 1984-07-25
Abstract: PURPOSE:To form the tap-controlled gas hot-water supplier, in which the transitional temperature fluctuation is controlled and the feed hot-water temperature is stabilized, by a method wherein a water amount signal operator, an average value operator and a differentiator are provided to effect a heat amount operation. CONSTITUTION:The frequency signal of a water amount detector 3 is introduced into the water amount operator 8 to obtain a water amount signal 9 proportional to the amount of water. When the amount of water (a) is chaned suddenly, the output (c) of the differentiator 12 exceeds the threshold value of a signal switching unit 13. Therefore, the water amount signal 9 is inputted into the heat amount operator 7 as it is, the change thereof is inputted into a proportional control valve 6 as it is and the amount of combustion is choked quickly, whereby the transitional fluctuation of feed hot-water temperature can be controlled to a small value. When the amount of water is stabilized, the output of the differentiator 12 becomes small and the signal switching unit 13 supplies the average value signal 11 of the average value operator 10 to the heat amount operator 7 and therefore, the proportional control valve 6 is driven by a stabilized signal (e), from which noise or the rotation varying component is removed, and the temperature of hot-water supplied during the normal operation of the supplier can be stabilized.

CONSTITUTION:When the image of an AF mark 5 is focussed and projected on the surface of a wafer, the image of the AF mark 5 on a slit 13 is clearly image-formed. The maximum quantity of light passing the slit 13 is obtained when the AF mark 5 is completely focused on the surface of the wafer 7 by having the size of the aperture of the slit 13 formed almost same as that of the AF mark 5. The quantity of light passing the slit 13 is detected by a light detector 14, it is converted to an electric signal and inputted to an arithmetic means 15. The stage 8 which retains the wafer 7 is shifted in the direction of optical axis of a projection optical system 6, and the condition of image formation of the AF mark 5 is changed. As a result, the Z-stage where the output signal obtained from the photo detector 14 becomes maximum can be positioned at the focusing position, namely, the position where the circuit pattern on the surface of a reticle 4 is projected and image-formed on the surface of the wafer 7.
