Patent JP-H08173700-A (JP)
Title: Steam iron
Inventor: YAMAGUCHI SHIGEKI
IPC: D06F75/18
Filed: 1994-12-21
Abstract: PURPOSE: To enable easy adjustment of steam flow without need for presetting the temperature. CONSTITUTION: A pressure sensing device 21 is provided on a handle 2. A control circuit 23 determines the quantity of water to be fed on the basis of the pressure sensed by the pressure sensing device 21 and the temperature of a base 3. The control circuit 23 regulates a motor-driven pump 16 so that a proper quantity of water A may be fed from a water tank 11 to a vaporizing chamber 12. A higher pressure sensed results in a larger quantity of water fed. The maximum quantity of water that can be fed is suppressed low when the temperature of the base 3 is low. When the wrinkles want more pressure, the user naturally applies more strength, and thereby the quantity of steam is increased. Reducing the maximum quantity of water to be fed at low temperatures prevents the dripping of water which otherwise will happen due to inadequate vaporization.

Abstract: PURPOSE:To appropriately display the change time of a dust bag by one piece of display element irrespective of whether suction force is large or small by providing a second pressure switch in a suction path and connecting it in parallel to a pressure switch, and connecting a switching element and a second pressure switch in series. CONSTITUTION:When a motor 12 is in the maximum rotation, dust collects fully in a dust bag, a pressure switch 17 installed in an air passage is turned on, an LED 18 is lighted, and a change time of the dust bag is informed.

Title: Secondary ion mass analyzer
Inventor: KAMESHIMA YASUBUMI
IPC: H01J37/252
Filed: 1987-12-18
Abstract: PURPOSE:To enable measurement and indication, together with its mass analysis, of the etching depth of a sample to be inspected which changes continuously by arranging a crystal oscillator near a sample holding part. CONSTITUTION:A crystal oscillator 6 is arranged near a sample holding part 3, and a film thickness meter is composed of this crystal oscillator 6, an oscillator 7 and a signal processing means 8. Since the oscillation number of this crystal oscillator 6 is reversely proportional to square root of the weight, even if it is small change it is measured accurately in electrical meaning. Though a sputtering phenomenon also changes delicately by impurity and grid defect, since there is an approximate bulk phenomenon in the first place, if mass of the bulk and sputter area are known in advance, it is easy to convert mass change into etching amount. Hereby, the etching depth of a sample to be inspected which changes continuously can be measured and indicated as well as its mass analysis.
