Filed: 1990-11-30
Abstract: PURPOSE:To readily correct the variation of an infrared detecting element due to deformation of a vibration resistant support by arranging a light emitting diode opposed to an array light sensor provided on the same plane as a pyroelectric infrared detecting element. CONSTITUTION:An infrared detector case 5 in which a pyroelectric infrared detecting element 1 is provided is placed on a structure 6 via a vibration resistant support 4, an array light sensor 2 is fixed to part of the case 5 so that it can have the same movement with the element 1, in addition a light emitting diode 3 is arranged in part of the structure 6 in opposition to the sensor 2, and a micro-lens is annexed in front of the diode 3 so that a micro-spot of about 50mumphi can develop on the light receiving plane of the sensor 2. In this way, the variation of the relative position of the element 1 to an infrared gathering system 7 can be detected with a space resolution of 50mum at about + or -1.6mm in maximum in the vertical and lateral directions. Then, a positional variation on two coordinates specifying the position of the detector on the plane normal to a light axis of the gathering system 7 is converted into the variation of a viewing azimuth depending on the position of a light spot on the sensor 2 for correction.

Title: Method for inspecting distribution of moisture
Inventor: MATSUOKA KATSUNORI
IPC: G01N21/3554
Filed: 1994-12-29
Abstract: PURPOSE: To determine the adhering state of moisture visually regardless of the temperature of an object by irradiating a surface to be inspected with a light of a specified wavelength band and capturing the light reflected thereon by means of an image pickup unit sensitive to the light in that wavelength band. CONSTITUTION: A surface A to be inspected is irradiated by an irradiation unit with infrared rays of a wavelength band in the range of 1.9-2.4μm where the moisture absorbs the light strongly. The reflected light is passed through a filter for passing the light of the same wavelength band, captured by an image pickup unit 2 comprising a combination of an infrared camera sensitive to the same wavelength band and an optical lens for visible light and visualized on a monitor 3. The filter may cut a wavelength band of about 3μm or above or about 2.4μm or above emitted from an object at normal temperature. This arrangement can eliminate the effect of light radiated from the object in the vicinity of normal temperature and the distribution of moisture can be inspected accurately. Consequently, physiological or psychological reaction in the form of perspiration can be measured or studied and the comfortableness of clothes at the time of perspiration can be evaluated.

Patent JP-H03204387-A (JP)
Title: Rotary gliding ship
Inventor: OGURA RIICHI
IPC: B63B1/18
Filed: 1989-12-31
Abstract: PURPOSE:To make the high speed running of a large ship possible by providing a rotary face of a rotary lift body which is symmetrical on both sides and rotates under water to give a lift to a ship body about in parallel with a water surface, forming slight irregularity on the rotary face, and providing a propelling machine on the ship body. CONSTITUTION:In propelling a rotary gliding ship 1 at high speed, when a rotary lift body 2 rotates under water, a rotary face 2b shakes off the water during its rotation to push a water surface downward for making its reaction give lift to the lift body 2. When the lift body 2 provided symmetrically on both sides on the side of a ship bottom 4a rotates under water, the rotation of the body 2 makes the lift act on a ship body 3 to float it up for decreasing the volume under water of the ship body 3, and propulsion resistance caused by the water against the ship body under water therefore decreases. In addition to that, since an irregularity on the rotary face 2b of the lift body 2 is slight, sliding action is easily generated between the rotary face 2b and the water surface to cause a sliding phenomenon during high speed propulsion. Thus the ship body 3 can be propelled as if it slides on the water surface.
