Title: Subscriber's line abnormality supervisory system
Inventor: SUDA HIROSHI
IPC: H04M3/24
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To detect connection with a reverse polarity by displaying a abnormal state of a subscriber line connecting to a subscriber's equipment in a reverse polarity when a current detection supervisory means provides an output of a detection output. SOLUTION: When a subscriber connection command is generated by a subscriber's line connection command generating means 1a in an intra-station device 1, a state of normal feeding is set. In this case, a current detection means 1b detects a current of a subscriber's line. When the subscriber's line is connected in a reverse polarity. Since the subscriber's equipment is observed to have a low impedance, a large current is supplied. However, the current flows through a standby circuit in the reverse connection and only a current less than a threshold level is detected by the current detection circuit. In this case, the polarity is inverted again by the subscriber connection command and the processing above is repeated.  When the detection current change is given to a current detection supervisory means 1d via an AND logic means 1c, the current detection supervisory means 1d generates an output representing a fault state when the means 1d detects the repetition of interrupt/connection of the current detection output indicates a preset period.

Title: Vehicle detecting device
Inventor: TOIDA SHINJI
IPC: G01S17/02
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To improve the quality accuracy of vehicle detection by outputting a first vehicle detection signal when the output of an amplification part is at equal to ore more than a specific level and outputting a second vehicle detection signal to a traffic information calculation part when a judgment control signal according to a road surface temperature signal is smaller than the second vehicle detection signal. SOLUTION: A distributor 17 distributes the output of an amplification part 14 to a first signal comparison part 15a and a second signal comparison part 15b. The second signal comparison part 15b outputs a signal when the output of the distributor 17 is at equal to or more than a specific level. A second vehicle detection part 16b outputs the output of the first vehicle detection part 16a as it is when the output of the second signal comparison part 15b is available. A road surface temperature detection part 18 measures the temperature of a road 2 and an object on the road and outputs a road surface temperature signal.  A vehicle detection judgment part 20 outputs the output signal of the second vehicle detection signal 16b to a high-speed information calculation part 7 as it is when the judgment control signal of a judgment control signal generation part 19 is smaller than the output signal of the second vehicle detection signal 16b. With this configuration, the discrimination is made possible to be carried out even a high-reflection object such as snow exists on a road.

Title: Floating magnetic head
Inventor: IKEDA NAOTO
IPC: G11B21/21
Filed: 1994-07-28
Abstract: PURPOSE:To keep displacement of a slider from obstruction. CONSTITUTION:A sticking part 44 for sticking to the slider 28 of a flexture 40 as a holding part is connected via a stepped part 43 having a prescribed height H to a displacement part 42. The stepped part 43 is molded integrally with the displacement part 42, for instance, by drawing work, etc. Since steps between the sticking part 44, the displacement part 42 and a fixing part 41 respectively in this floating magnetic head 14 can be made large enough, when the slider 28 is acted by rotating force, the slider can freely be displaced in all directions without influencing the fixing part 41 and the displacement part 42. Consequently, since even a magneto-optical disk having a large wobble can faithfully be followed up, the disk is prevented from flawing, and hence the reliability can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a power generator at a low-power time by outputting the output of each generator in a sharing state in accordance with the rotating speeds of the generators. SOLUTION: The speed reference at which a propeller 1 outputs the maximum power is found by using an anemometer 31, a speed detector 32, and a speed reference section 33.

Title: Hot-water supply apparatus
Inventor: INAGAKI HIDEO
IPC: F23N1/00
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a hot-water supply apparatus wherein the combustion amount of a burner does not exceed the maximum combustion amount even when there is an unevenness in a supply gas. SOLUTION: During a hot water discharging motion, a controller calculates (S4) the calory being utilized for the heating of water by the difference between a supply hot water temperature and a fed cold water temperature, and the sum of a fed cold water flow rate, and compares the calculated value and a previously stored reference value (S5). When the calculated value exceeds the reference value (S5:YES), it is judged that the combustion amount of a burner has exceeded the maximum combustion amount by a reason such as the Wobbe index of a gas to be fed is large, or the content of butane is high, and the opening degree of a proportional valve is adjusted in the closing direction to reduce the amount of the feeding gas (S6), and the combustion amount of the burner is reduced, and when the calculated value becomes the reference value or less, the adjustment is completed (S5:NO).

Title: Diluted gas supply device
Inventor: YADA HISASHI
IPC: H01L21/31
Filed: 1989-07-10
Abstract: PURPOSE:To simplify the device and to dilute a raw material gas with high accuracy during the operation of the device without generating fluctuation of dilution ratio by combining one mixing chamber with a 1st to a 4th gas flow rate adjusting means so as to carry out a specified action. CONSTITUTION:A nonreturn valve 7 is inserted in the flow passage of carrier gas in the influent side of the mixing chamber 6. When the pressure drops in mass controllers 1, 2 are large and the flow velocities are large, it means that the pressure in the mixing chamber is low, and the nonreturn valve is widely opened to increase the flow rate of carrier gas. When the pressure drops in the mass controllers 1, 2 are small and the flow velocities are small, the opening of the nonreturn valve becomes small to decrease the flow rate of carrier gas. Thus, the device has the function that the carrier gas is made to flow into the mixing chamber 6 so that the ratio of the flow rate of raw material gas to the flow rate of carrier gas is to be as nearer as possible to the target dilution, that is, the function that controls the flow of carrier gas according to the states of raw material gas side.

IPC: G01R31/28
Filed: 1989-07-10
Abstract: PURPOSE:To obtain a waveform generator with simple constitution by selecting either one piece of waveform data passing through two routes and blanking the selected data with a clock. CONSTITUTION:A selection circuit 8 selects undelayed waveform generating data 7b1 and delayed waveform generating data 7b2, and when the setting of blanking timing is positioned on the first half of the period of waveform generating data, applies the undelayed waveform generating data 7b1 to a blanking circuit 9. When the setting of the blanking timing is positioned on the latter half of the waveform generating data, the delayed waveform generating data 7b2 are applied to the circuit 9. Thus, all the waveform generating data can be blanked. Since the waveform generator can be attained by the simple constitution, the constitution of an IC testing device can be simplified.

Title: Dielectric strength measuring circuit of operational amplifier
Inventor: YAMADA TOMOU
IPC: G01R31/316
Filed: 1980-12-15
Abstract: PURPOSE:To measure the dielectric strength within an active region, by supplying a 1/2 power supply voltage to a noninverse input and connecting an inverse input to an output to vary the power supply voltage. CONSTITUTION:An inverse input terminal 3 is connected to an output terminal 4 to form a voltage follower of a 100% feedback. Resistances 8 and 9 constitute a voltage dividing circuit 11 and then function as the bias resistance to divide the voltage VCC of a curve tracer 7 down to 1/2 and then to apply it to a noninverse input terminal 2. Under such conditions, the terminal 4 functions as an amplifier of double voltage gain to the noninverse input 2 to always keep an active state of 0.5VCC. Thus the accurate dielectric strength can be measured in an working region having a stable state of actual use regardless of the value of the voltage VCC.
