Title: Moisture measuring apparatus for dryer
Inventor: HORI KEIICHI
IPC: G01N22/04
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To obtain a moisture measuring apparatus which is provided at a dryer used to dry an object to be treated, by using microwaves and by which the initial moisture weight and the moisture of the object to be treated can be measured on-line and in a noncontact manner. SOLUTION: Microwaves which are generated by a mocrowave oscillator 51 are guided into a dryer through a waveguide 52, so as to be directed at an object to be heated and dried. Microwave incident power which is generated by the microwave oscillator 51 and microwave reflected power which is reflected by the object to be treated so as to be returned through the inside of the waveguide 52 are measured by a power monitor 55. A computing device 503 computes and processes the relationship between the microwave incident power and the microwave reflected power. Thereby, the initial moisture weight of the object to be treated, before being treated and the moisture of the object to be treated, which is heated and dried are found.  That is to say, by making use of a phenomenon where the microwave reflected power increases as the moisture of the object to be treated is lowered when the microwave incident power is kept constant, the initial moisture weight and the moisture are estimated and computed.

Patent JP-S6383615-A (JP)
Title: Level gauge
Inventor: YAMASHITA YUTAKA
IPC: G01F23/22
Filed: 1986-09-29
Abstract: PURPOSE:To reduce the vaporization amount of cryogenic liquid (e.g. liquid helium) and to shorten the time required to measure a liquid level by reducing the heating value from the normally conductive part of a superconductor even if the liquid level of the cryogenic liquid. CONSTITUTION:Current terminals 14a-14e are fitted to the superconductor 13 and sections among the respective terminals are determined as liquid level measurement sections; and a current is supplied from a current source 17 to each liquid level measurement section and the current deflection of a voltmeter 19 is read to judge whether the liquid level is present in the section or not from the state, thereby measuring the liquid level. Therefore, even when the part where a line 13 is exposed above the liquid surface becomes larger owing to a drop in the liquid level, the range where the current flows is limited to a short section of the liquid level measurement section, so the heating value caused by the normal conduction state of the line 13 decreases and the heating value of the liquid helium 12 decreases. Further, the range where the normal conduction state is limited to a liquid level measurement section nearby the liquid surface, so the time up to an entry into the voltage balanced state becomes short and the time required for liquid level measurement is shortened to reduce the vaporization amount of the liquid helium 12.

Title: Method for determining flaw in magnetic particle test
Inventor: NAGATA JUNICHI
IPC: G01N27/84
Filed: 1985-10-14
Abstract: PURPOSE:To make it possible to automatically determine a flaw, by adopting a low angle illumination method such that the irradiation angle of a light source is set to about 10 deg. and the angle of a TV camera to about 50 deg. and removing noise with a diameter of 1mm or less in an image by image processing. CONSTITUTION:A magnetic powder 4 is scattered and an object 1 to be inspected is magnetized by a magnetic powder flaw detection apparatus 3 and the unnecessary part of the scattered magnetic powder is removed by an air blower 11 so as to leave the magnetic powder film of a flaw part. The set angles of an illuminator 5 and a TV camera 6 are respectively set to about 10 deg. and about 50 deg. in the same side to a perpendicular line to photograph the surface of the object 1 to be inspected. Herein, light from the magnetic powder 4 adhered to the flaw part is irregularly reflected and a video signal is inputted to an image processor 8 in parallel to a monitor TV7. Because the signal of the residual magnetic powder capable of being removed by the blower 11 is contained in the video signal, binarization is performed on the basis of a properly set video signal. Further, by shaking off noises scattered in a spot like state using a mesh having a mesh diameter of 1mm, only flaw indication can be extracted and the output of the apparatus 8 is marked by a marker 9 and recorded on a recorder 10.

Title: Humidifier
Inventor: OGAWA TAKEYASU
IPC: F24F6/00
Filed: 1986-09-25
Abstract: PURPOSE:To remove impurities from water remaining in the interior of a bag belt form hydrophobic porous sheet and prevent humidifying performance from being lowered, by providing a water-supplying pipe at one end part of the sheet, providing a water-discharging pipe at the other end part, providing a flow control valve in the water-discharging pipe, and discharging a small quantity of water through the valve. CONSTITUTION:When water in a humidifying element 40 is evaporated to perform humidification, the water level in a water tank 7 is gradually lowered, and when it is lowered to a water level A, a float switch 9 is closed to open a solenoid valve 8, whereby water is supplied into the tank 7. When the water level in the tank 7 is raised to a water level B, the switch 9 is opened to close the valve 8, whereby the supply of water into the tank 7 is stopped. When humidification is thus conducted, the concentrations of impurities in the water in the humidifying element 40 are increased, and the water thus fouled is discharged through a water-discharging pipe 6 into a drain pan 11 by opening a flow control valve 10. In this case, the quantity of water discharged through the valve 10 is controlled to a minimum water quantity which does not reduce the humidifying performance, whereby the quantity of water uselessly discharged is minimized, the impurities contained in feed water or the like are discharged, and the humidifying performance can be prevented from being lowered.
