  • Patent number: 10816576
    Abstract: In a cooling device 20 of the present invention, a bypass passage 20C for allowing circulating liquid to partly or wholly bypass a heat exchanger 15; a first valve 21; and a second valve 22 are provided. Thus, the a cooling device 20 having a refrigerator 100 capable of cooling to a low temperature can be operated even at high temperature and heat can be removed even when the inspection temperature is high. Thus, the inspection can be performed both cases when the inspection temperature is high and low. Consequently, the semiconductor wafer generating a large amount of heat during the inspection can be also inspected without causing problems.

  • Publication number: 20110060228
    Abstract: In order to supply a method and a device that can evaluate the fluidity of blood with good sensitivity in a simple manner, there is provided a blood fluidity evaluation method in which a pressure member is pressed against a test site upon a test subject, blood at the test site is squeezed to flow out to the periphery of the test site, change over time of the amount of blood at the test site is measured at this time using optical scattering, and blood fluidity at the test site is evaluated from this measurement data; and, desirably, before the above method, a positioning process is performed in which: the pressure member is pressed against the test site with a weak force; pulse measurement data is acquired due to the absorption of light; and a relative position, at which the intensity of the pulse measurement data attains a local maximum, is determined as being an optimum measurement position.

  • Publication number: 20060173558
    Abstract: The manipulated variable is calculated solving transfer equation (R=q·R+a·C+b·D. Multiplication symbol “·” means convolution R is the controlled variable. C is the manipulated variable. D is the disturbance that is caused by program or is measured. The degree of each q, a, and b is &q, &a, and &b. &a must be greater than peak period of impulse response function.) under the condition that R becomes same as the command value (S) &q periods after, C becomes constant &q periods after, and D can be fed forward till &q+&a?&b periods after. Thus control error becomes very small even when S and D change complicatedly and step wise. (FIG. 8) Parameters (q, a, and b) are tuned using only such differences of R, C, and D, which have sufficient significant digits and only when estimation error is allowable. So that the system can keep stability even if very large not fed forward disturbance happens during automatic tuning.

  • Publication number: 20040133286
    Abstract: The manipulated variable is calculated as a linear form of the command of fixed periods after and such data from fixed periods before, that are controlled variable until the present period, manipulated variable until the last period, and measurable disturbance until fixed periods after. The number/order of needed values is determined by order systemisation and is limited in small number. And coefficients are calculated solving propagator equation called COFRE under FT-determining. Using the deviation of estimation gap, changing of the system and the occurrence of not measurable disturbance are judged. When changing of the system is judged control parameters are tuned fast, and when the occurrence of not measurable disturbance are judged automatic tuning is stopped in order to avoid from that parameters are broken. The control period is also automatically optimised. The invented method is applicable for from the simple system to the complex system.

  • Patent number: 5167916
    Abstract: A novel ladle and method for spheroidizing molten iron is disclosed. A cover made of a porous body defining continuous blow holes is mounted at the upper portion of ladle main body containing spheroidizing material therein, and spheroidizing is effected by pouring molten metal into the ladle main body through the porous body cover. Alternatively, the cover is partly cut-away, and spheroidizing is effected by pouring molten metal into the ladle main body through the cut-away portion of the cover.

  • Patent number: 4223657
    Abstract: A safety device for controlling an ignition circuit for an internal combustion engine associated with a transmission coupling the engine to a load comprises a thyristor adapted to permit, upon conduction thereof, the ignition circuit to produce a high voltage to fire a spark plug provided in the engine, a position-responsive switch adapted to permit application of a trigger signal from a power supply to the gate of the thyristor only when the transmission is in neutral, and a capacitor coupled across the gate and cathode of the thyristor to be charged by a voltage drop thereacross and to provide a trigger signal to the gate of the thyristor. Once the capacitor is charged it maintains a condition wherein the thyristor is turned on whenever the thyristor is positively biased even after the transmission is in gear.

  • Patent number: 4193385
    Abstract: An engine stopping device for stopping an internal combustion engine provided with an ignition system energized by a generator driven by the engine. The stopping device comprises a switch for making ineffective at least one of the elements of the ignition system, an actuator for actuating the switch into the operated state and a retaining device for retaining the switch in the operated state until the engine is brought to a standstill. Although it takes time for the engine to be brought to a standstill, the operator just has to give the actuator one touch operation, such as pressing a button, and may release the actuator before the standstill. Subsequent starting of the engine requires no extra operation.

  • Patent number: 4119076
    Abstract: An ignition system for an internal combustion engine having an AC generator compriss an ignition coil energized by an output from the generator. At an angle in advance of ignition timing, a first thyristor connected across the generator output terminals is turned on to permit a short-circuit current therethrough. A capacitor is charged by an output from the generator, and is discharged through a second thyristor which is triggeed at the ignition angle. The discharge current is reversely applied to the first thyristor and the first thyristor is turned off. Interruption of the short-circuit current through the first thyristor leads to a large current through the primary of the ignition coil, causing a high voltage in the secondary with resultant spark in the ignition plug.

  • Patent number: 4034731
    Abstract: An ignition system for an internal combustion engine having an AC generator comprises an ignition coil energized by an AC output from the generator. A first thyristor is connected in series with the primary of the ignition coil and permits and interrupts the current through the primary. The first thyristor is turned on at a first angle in advance of ignition. A capacitor is charged by an AC output from the generator, and is discharged when a second thyristor conducts to apply a reverse voltage across the anode and cathode of the first thyristor. The second thyristor is triggered at a second angle.
