Title: Phase detection circuit
Inventor: YAMASHITA KATSUHIRO
IPC: H03D13/00
Filed: 1987-04-21
Abstract: PURPOSE:To take out a detection output signal without being affected by the drift of a phase detector, etc., by interlocking and switching the polarity of the reference signal (or the input signal) of a phase detector and that of the detected output of the phase detector by a clock signal. CONSTITUTION:A 180 deg. phase shifter 3 and a switch 7 are provided on the reference signal side of the phase detector 1. Also, an inversion circuit 4, a non- inversion circuit 5, and switch 8 are provided on the output side of the phase detector 1. When a plus drift voltage(+Vd) exists on the phase detector 1, (+Vo+Vd) and (+Vo-Vd) appear on the output(point C) of the switch 8 at the cycle of clock signal. The clock signal is eliminated by passing the signal through a low-pass filter 2, and only the detected output(+Vo) is outputted, thereby, the detection output signal can be obtained without being affected by the drift voltage.

Title: Apparatus for preventing water heater from being frozen
Inventor: MURAKAMI HIROKUNI
IPC: F24H1/10
Filed: 1982-06-04
Abstract: PURPOSE:To prevent readily and positively a water heater from being frozen without letting water remain running, by connecting a water supply conduit and a hot water delivering conduit of a heat exchanger through by-passes, and circulating water in the heat exchanger by a motor pump in case the freezing is apprehended. CONSTITUTION:A boiler body W is connected with a tap 12 via a hot water supply piping 11. A by-pass 13 branched from the hot water delivering conduit 8 of a heat exchanger 1 is connected with the outlet of a motor pump 14. The inlet of the motor pump 14 is connected with the water supply conduit 6 through a by-pass 15. Thus, in normal operation, when the tap 12 is opened or closed, a water flow switch 4 responds to it to serve hot water. The motor pump 14 is controlled by the signal from a thermostat 16, in case the tap 12 is closed, that is, in case the heat exchanger is not in operation. When ambient temperature of the heat exchanger 1 has lowered to a freezing range, the thermostat 16 causes the motor pump 14 to be driven, so that the water in the heat exchanger 1 is circulated via the water supply conduit 6 and the hot water delivering conduit 8 and therefore the water is prevented from freezing.

Title: Sulfur dioxide reducing method
Inventor: AKIMOTO HIDETOSHI
IPC: C01B17/04
Filed: 1979-08-01
Abstract: PURPOSE: To obtain elemental sulfur without causing environmental pollution by allowing an SO 2 -contg. gas to contact to tar-freed dry distilled coal at a specified temp.  
     CONSTITUTION: Elemental sulfur is taken out of an SO 2 -contg. gas without exerting unfavorable influence due to tar. Dry distilled coal is prepared by dry distilling coal at ≥700°C for about 20min to attain ≥98% tar removing rate. The SO 2  concn. of the gas is preferably ≥5vol%, and a lower oxygen content is desired. Water is preferably contained as little as possible, and it is desirable that the molar ratio of H 2 O/SO 2  is ≤3. The reaction temp. is adjusted to 700W900°C. For example, coal of about 5mm diameter is dry distilled with inert gas at 700°C for 30min, and 1l dry distilled coal is packed in a column of about 100mm diameter. A gas consisting of 10% SO 2 , 10% CO 2  and the balance N 2  is fed into the packed column at 5Nm 2 /hr velocity and ≥700°C. Thus, the SO 2  is reduced to S without detecting COS, CS 2  and H 2 S.
