Title: Ultrasonic flaw detector
Inventor: FUJII MINORU
IPC: G01N29/26
Filed: 1982-10-26
Abstract: PURPOSE:To prevent an ultrasonic flaw detector from being broken or damaged, by providing an external-size measuring device for measuring the external size of an object to be inspected, and a comparator means for confirming that the value measured by the external-size measuring device and the standby position of a following device are in conformity with each other. CONSTITUTION:A conveying drive unit 10 conveys an object 1 to be inspected on the basis of a conveying control signal. When the object 1 enters the flaw detector, an external-size measuring device 13 installed at the entrance measures the external size of the object 1 and outputs the measurement result to a comparing control unit 14. The control unit 14 makes comparison between the measurement result from the external-size measuring device 13 and the following device standby position set value delivered from a mechanism device 4. When these values are not in conformity with each other, the control unit 14 delivers a control signal to a conveying control unit 9 in order to suspend conveying of the object 1.

Abstract: PURPOSE:To permit to prevent the deterioration of characteristics, stopping trouble or the like surely by a method wherein the level of operating liquid in an evaporating section or an operating liquid tank is detected and the amount of shortage of the operating liquid is supplied based on the detecting value. CONSTITUTION:Operating liquid is circulated from the evaporating section 1 to the same section through a vapor pipe 3, a condensing section 2 and a condensed liquid pipe 4. An operating liquid tank 6 is provided below the condensing section 2 and a supplying pipe 9, provided with an automatic valve 7 and a supplying pump 8, is attached thereto. On the other hand, a bypass tank 11, provided with a liquid level switch 10, is formed in the evaporating section 1 to detect the level of the operating liquid in the tank 11. The automatic valve 7 is opened by a lower limit switch, for example, to operate the supplying pump 8 and supply the operating liquid into the closed circuit while the automatic valve 7 is closed by an upper limit switch to stop the supplying pump 8. Thus, the insufficient operating liquid in the device is supplied automatically and thereby holding the level of operating liquid in the evaporting section 1 at a proper value at all times. The level of the operating liquid may also be detected by attaching the level switch directly to the inside of the evaporating section 1.

Title: Digital phase demodulation circuit
Inventor: MIZOGUCHI TAMIYUKI
IPC: H03H19/00
Filed: 1992-07-16
Abstract: PURPOSE:To prevent the degree of frequency selection of a band-pass filter from deteriorating and inter-code interference, etc., from occurring even when the carrier frequency of a digital phase modulation signal is deviated. CONSTITUTION:The digital phase modulation signal S1 is inputted to a switched capacitor filter 1 which secures the degree of frequency selection and comprises the band-pass filter to minimize the inter-code interference. The switched capacitor filter 1 is driven by a reference clock CK1 outputted from a voltage controlled oscillation circuit 3. When the carrier frequency f1 of the digital phase modulation signal S1 is deviated to f1+DELTAf1 due to an unknown cause, the reference clock CK1 is also changed, and as a result, the center frequency of the switched capacitor filter 1 is also deviated to f1+DELTAf1, which prevents the degree of frequency selection from deteriorating and the inter-code interference, etc., from occurring.

Abstract: PURPOSE:To eliminate the need for the regulation of a pulse width by detecting that a voltage generated in a voltage generating resistor is changed when an arbitrary switch out of the plural switches is inputted, the voltage corresponding to the arbitrary switch is sent to an electronic control part, and one switch out of the plural switches is inputted. CONSTITUTION:An electronic control circuit 3 outputs a signal from a terminal 3a, turns on transistors(TR) 10a and 10b, and then, it is energized to a serial resistance circuit between a serial resistor group 5 and a voltage generating resistor 5e. At such a time TRs 9a and 9b are turned off. Here, when the resistance values of resistances 5a to 5e are set respectively at RA to RE, switches 6a and 6b are both turned off, and a supply voltage is set at V, for a potential Vin at a terminal 3b of the electronic control part 3, an expression I is obtained. Next, the switch 6a is turned on, an expression II for the potential Vin is obtained, by turning on the special switch, the potential of a terminal 3e of the electronic control part 3 is different, and which switch is turned on can be identified. Thus, the pulse width regulation can be made unnecessary.

Title: Method and device for treating substrate
Inventor: SASAKI TADASHI
IPC: G03F7/30
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a method and device by which a substrate can be cooled evenly in a short time. SOLUTION: When a substrate W heat-treated in a baking section after exposure is carried in a development treating section 20, pure water is supplied by opening a valve 14 for cooling the substrate W with the pure water. While the pure water is supplied to the substrate W, the substrate W is cooled efficiently, because the pure water is evenly spread throughout the surface of the substrate W by rotating the substrate W by means of a motor M. When the substrate W is cooled with the pure water in such a way, the substrate W can be cooled efficiently in a short time because the pure water directly comes into contact with the substrate W.  When the cooling treatment of the substrate W with the pure water is completed, development is started by the supply of a developing solution adjusted to a prescribed temperature from a nozzle 24, but the efficiency of the development can be improved, because the prewetting treatment for development can be performed simultaneously with the cooling treatment.
