IPC: G02B6/12
Filed: 1993-07-27
Abstract: PURPOSE:To provide a method for measuring the refractive index of a planar optical waveguide without immersing the measuring system into a matching oil. CONSTITUTION:Light from a laser light source is condensed through a condenser lens to be focused at the edge of a planar optical waveguide 1. An irradiating light 3 and the waveguide 1 are then shifted relatively and the light leaving the waveguide 1 is measured by a light receiving element 2. A transparent spacer 4 is interposed between the waveguide 1 and the light receiving element 2. The light beam projected to the edge of the waveguide 1 is retracted to enter into the waveguide 1 thence enter through the spacer 4 into the light receiving element 2. Absolute refractive index of the planar optical waveguide 1 can be calculated with reference to a known refractive index of the spacer 4.

Filed: 1986-09-03
Abstract: PURPOSE:To effectively obtain answers to each question by estimating the purposes of these questions regardless of the number of items forming the questions even though the input question contents have omissions or conflicts. CONSTITUTION:The contents of each component item are obtained for a selectively input question out of the plural candidates of item contents shown for each question component item.

Title: Magnetic tape device
Inventor: YONEZAWA NORIHIRO
IPC: G11B15/665
Filed: 1986-09-01
Abstract: PURPOSE:To engage and disengage a tape drawer body without requiring strong pressing force, by loading and unloading the tape drawer body interposing a prescribed arm, and a cam plate, when the tape drawer body is fixed on a fixed body. CONSTITUTION:An arm 55, and the cam plate 59 are supported in such a way that they can turn freely, on shafts 63 and 64 in the neighborhood of the fixed body 19 of a base 5, and they are pressed by springs 60 and 61, respectively. When a motor 19 is driven to draw out a tape, the pole 50 of the drawer body 9 presses the cam plane 59a of the cam plate 59, and releases the prohibited state of the turning of the arm 55, therefore, the pole 50 is locked by the hooking part 55a of the arm 55, then being fixed. Also, when fixing is released, since a connector pin 37 rotates the cam plate 59, the pole 50 is separated, thereby, the fixing is released. In this way, it is possible to engage and disengage the drawer body without requiring the strong pressing force for the fixing.

Title: Magnetic resonance imaging diagnostic device
Inventor: ISHIHARA YASUTOSHI
IPC: A61B5/00
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To ensure a testee's safety, regarding a temperature rise therein due to the application of high frequency magnetic field. SOLUTION: This device is formed so that a plurality of types of high frequency magnetic field are applied to a testee placed within static magnetic field generated with a main magnet 10 via a high frequency probe 16, and an excited magnetic resonance signal train is measured with the high frequency probe 16. In this case, measurement start timing for the prescribed magnetic resonance signals is delayed from the timing for others among the magnetic resonance signal train. Alternatively, timing for applying reversed pulses corresponding to the prescribed magnetic resonance signals is delayed from the timing for others among the magnetic resonance signal train. As a result, phase information associated with a temperature change can be acquired with a receiver 18. A temperature change in a testee is calculated on the basis of the phase information so obtained.
