Title: Time base error detection circuit for reproducing video signal in video disk player
Inventor: FURUICHI TOKIKATSU
IPC: H04N5/95
Filed: 1988-09-01
Abstract: PURPOSE:To set only one stable point by detecting phase difference between a burst signal included in a reproducing video signal and a reference subcarrier signal, adding their output, and outputting it as a time base error signal. CONSTITUTION:At a first phase difference detection circuit 3, a horizontal synchronizing signal 1 is compared with a reference synchronizing signal 2, and no signal is outputted by output impedance when the lead or lag of a phase between both signals exists within a prescribed range, and the signal with a different logic level is outputted when the lead or lag exceeding the prescribed range exists. Also, a second phase difference detection circuit 6 inputs the burst signal 4 and the reference subcarrier signal 5, and it is formed so as to be constituted of an exclusive OR circuit which outputs exclusive OR output between both signals as the phase difference output between both signals. In such a way, the time base error signal in which only one stable point exists is outputted to the output of an adder 7 which adds and outputs the output of the first phase difference detection circuit 3 and that of the second phase difference detection circuit 6.

Title: Apparatus for feeding secondary air to intake system of internal-combustion engine
Inventor: HASEGAWA SHIYUNPEI
IPC: F02M23/04
Filed: 1982-12-10
Abstract: PURPOSE:To improve the performance of an engine and to control the air-fuel ratio over a wide range, by executing PI-control of the secondary air by detecting the air- fuel ratio from the output signal of an oxygen-density sensor in connection with a flow control valve which changes the sectional area of a secondary-air passage according to the fluid pressure. CONSTITUTION:When a negative pressure PB is acted in a vacuum chamber 33a through a negative-pressure detecting hole 8, an air valve 33 is opened and open air is introduced into an aspirator 3 from an open-air inlet port 34. With decreasing of the opening of the air valve 33 due to drop of negative pressure Pe and opening of a control valve 32 caused by the pressure difference between negative pressures Pv and P1, the flow rate of air passed through a control suction passage 35 is also decreased and the negative pressure P1 is lowered, so that the control valve 32 is closed and the negative pressure Pe is raised again. Then, the above process is repeated. A control circuit 53 judges whether the mixture is rich or not by detecting whether the output voltage of an oxygen-density sensor 54 is higher than the theoretical air-fuel ratio voltage or not, and proportional and integral control of the secondary air is executed by opening or closing passages 11a, 42a by solenoid valves 15, 43 and producing a ''rich'' signal and a ''not rich'' signal alternately and continuously.

Title: Electrodeless electric-discharge lamp
Inventor: SHINOMIYA MASAKI
IPC: H01J65/04
Filed: 1984-10-17
Abstract: PURPOSE:To improve the coupling efficiency between an electrodeless electric- discharge lamp and a magnetic path body, consisting of a ferromagnetic substance and extending along the outer surface of the bulb, and minimize the electric wave disorder by installing the magnetic path body in relation to the coil. CONSTITUTION:The inner surface of an almost spherical glass bulb 1 is coated with a phosphor 2. After the bulb 1 is evacuated, it is charged with mercury and a rare gas such as argon or krypton. A semispherical magnetic path body 5 consisting of a ferromagnetic substance such as a ferrite material or a pressed- powder iron core is installed in such a manner as to cover a coil 3 thereby covering an almost semispherical outer surface of the bulb 1 by the body 5. When a high-frequency current is fed through the coil 3, a great part of the magnetic flux produced flows through the magnetic path body 5 outside the coil 3 and through the internal space of the bulb 1 inside the coil 3. The magnetic flux passing inside the bulb 1 generates a strong electric field which then ionizes mercuric vapor. Part of the mercuric vapor is excited to produce ultraviolet rays. The thus produced ultraviolet rays are then converted into visible light by means of the phosphor 2 applied to the inner surface of the bulb 1.

Abstract: PURPOSE:To improve a heat transfer performance of nitrogen gas on a second liquid chamber side by installing a liquid drainage to the upper part of a condensation vaporizer, a liquid medium introduction passage and a liquid medium vaporization passage to a first liquid chamber, and circulating the liquid medium through the liquid drainage and the first liquid chamber, allowing the liquid medium to be vaporized. CONSTITUTION:Liquefied oxygen LO distilled in a upper tower 6 is introduced into a liquid drainage 25 by way of a liquefied oxygen intake pipe 30. It flows down through a liquid medium intake passage 27 in an oxygen chamber 21 and is introduced into each vaporization passage 28a of a liquid medium vaporization passage 28 by way of a communication passage 29. The liquefied oxygen is heated by nitrogen gas introduced into a nitrogen chamber and is partially vaporized and turned into oxygen gas GO and rises as a gas liquid mixed flow. This gas liquid mixed flow is separated at the liquid drainage 25. The oxygen gas GO is partially output as a product, the rest of which is turned into a rising gas in the upper part tower 6. The oxygen gas is also output as a product or a safety liquid acid. A greater portion flows into the liquid medium intake passage 27 once again and circulates through the oxygen chamber 21. It is, therefore, possible to operate a condensation vaporizer with a minimum quantity of liquid medium.
