Title: Combustion apparatus
Inventor: KIMURA YOICHI
IPC: F23C99/00
Filed: 1993-05-14
Abstract: PURPOSE:To optimize a combustion state by correcting the amount of supply air by detecting a change in an excess air rate based upon detected temperature when the excess air rate is changed from an optimum set value. CONSTITUTION:Lean mixed air is subjected to a thermal influence of a rich flame formed on a first flame port 1 and is fired to form a thin flame. The thin flame contains abundant oxygen after combustion and is forcedly supplied to the rich flame for high load combustion. Temperature detected by temperature detection means 17 is chiefly changed owing to the amount of combustion and an excess air rate so that once the amount of combustion is determined, the excess air rate and the temperature detected by the temperature detection means 17 have a fixed relationship. As the amount of combustion is increased, the amount of air supplied to a second flame port 15 including the temperature detection means 17 provided thereon is more supplied by air amount control means 25 compared with the whole of a combustion portion whereby the excess air rate at the second flame port 15 is increased to keep unchanged the temperature upon combustion in a combustion state where the excess air rate is optimum even if the amount of combustion is varied.

IPC: H04N5/12
Filed: 1988-05-10
Abstract: PURPOSE:To contrive constant AFC circuit sensitivity even in a variable horizontal oscillating frequency by applying the output voltage of an FVC to an AFC circuit to which a horizontal synthesizing signal is applied and making the sensitivity of the AFC circuit constant not depending on the horizontal frequency of an input signal. CONSTITUTION:A multi scanning type television receiver adds the horizontal synthesizing signal of an input signal to a frequency-voltage converting circuit FVC31, adds this output voltage to a horizontal deflecting circuit, changes-over this horizontal frequency and image-receives the input signal of a different horizontal frequency. In this image-receiver, the output voltage of the FVC31 is applied to an AFC circuit 30 to which the horizontal synthesizing signal is applied and the AFC sensitivity of the AFC circuit 10 is made constant not depending on the horizontal frequency of the input signal. Thus, even when a horizontal oscillating frequency is variable, the AF sensitivity of the AFC circuit 10 is constant, the loop gain and the pull-in-range of the AFC circuit 10 can be kept constant and a satisfactory image-receiving can be executed.

Title: Damper
Inventor: MAEDA HIROYUKI
IPC: B60G17/08
Filed: 1990-04-27
Abstract: PURPOSE:To quickly generate damping force and thereby lessen delay in response by making up an orifice out of a throttle hole formed in a switch-over valve, and of a needle valve which is fixed on the wall of an auxiliary oil chamber which is faced to the throttle hole while being extended into the throttle hole. CONSTITUTION:An orifice 72 which mutually connects a first and a second auxiliary oil chamber 68 and 70, is made up out of a throttle hole 72a formed in a switch-over valve 66, and a needle valve 72b which is fixed on the wall of the first auxiliary oil chamber 68 faced to the switch-over valve. The switch-over valve 66 quickly starts moving with the pressure of the first auxiliary oil chamber 65 quickly increased. This thereby causes the pressure of the second auxiliary oil chamber 70 to be increased, and consequently causes a plunger 82 to be pressed down, so that oil in the second auxiliary oil chamber 70 to run away to a lower pressure side main oil chamber 54 while speeds are lowered therein. When the opening of the orifice 72 is increased in area with the switch-over valve 66 lowered down, the difference in pressure between the first and the second auxiliary oil chamber 68 and 70 is abruptly decreased, so that the switch-over valve 66 is thereby quickly restored. By this constitution, damping force is quickly generated, and delay in response is thereby lessened.

Title: Evaluating method for creep life expectancy of high temperature equipment
Inventor: GOTO TORU
IPC: G01N3/00
Filed: 1988-05-10
Abstract: PURPOSE:To evaluate life expectancy with high accuracy by estimating a creep chart and a creep rupture chart before use from the hardness of the high- temperature equipment before use. CONSTITUTION:A creep curve is determined based upon data on a received material test result document. The obtained creep curve is used to calculate variation in creep stress with time together with the temperature of a rotor. Then a hardness variation ratio chart is determined based upon the data of the received material test result document. The ratio of hardness up to a current point at a position where the life expectancy is to be found is estimated from said chart. Then the hardness is measured and the hardness before use is calculated from the result of the estimated value. The creep and creep rupture chart before use are estimated based upon the obtained hardness before use and chemical composition entered into the material test result document. Creep damage is calculated from them. Then the use time up to now is subtracted from the time when the creep damage reaches 1. The obtained result is the life expectancy.

Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To continuously produce a large amount of non-monocrystalline semiconductor thin film having a large area and a high photoelectric conversion, especially, photovoltaic devices. SOLUTION: In discharge space of a plasma CVD device, band members are moved in a lengthwise direction, and parts of a cathode 1002 for application of high-frequency electric power are formed into partition electrodes 1003, such that the entire area of the cathode 1002 in contact with the electric discharge space is larger than the sum of the surface area of anode 1004 and that of the band members, which move in the lengthwise direction, in contact with the discharge space. Further, during glow discharge, the cathode 1002 maintains, as its self bias, a positive potential higher than the potential of the anode 1004 by +5V or greater, and the potential is applied to the band members, which move in the discharge space, via the partition electrodes 1003.  Next, various material gases are introduced around the surface of the band members and regions comparatively far from the band members independently by a plurality of material-gas inlet pipes. Thus, non-monocrystalline semiconductor thin films are continuously produced on the band members by plasma CVD.

Title: Multistage output switching power supply device
Inventor: FUKUCHI TAKESHI
IPC: G05F1/56
Filed: 1981-07-22
Abstract: PURPOSE:To realize the independent stabilization only for the output to be stabilized, by turning on and off a switching transistor with a certain timing and at the same time providing a regulator at the output side. CONSTITUTION:A transformer T3 is set to an AC power supply 1 in parallel to a full-wave rectifier 2, and a timer IC3 is set at the secondary side of the transformer T3. A transistor (TR)Q2 is turned on and off by the timer IC3 with a constant frequency duty. As a result, a TRQ1 turns on and off a primary coil of a transformer T1 via a transformer T2 with the timing decided by the timer IC3. Thus the voltage is induced at the secondary coils n2-n4 in accordance with the turn ratio. This induced voltage of high output accuracy is delivered via a rectifying circuit consisting of a capacitor input and then the regulators IC1 and IC2. In such way, only the output to be stabilized can be stabilized independently.
