Title: Karman vortex sensor
Inventor: MACHIDA HARUHIKO
IPC: G01F1/32
Filed: 1989-12-13
Abstract: PURPOSE:To accurately detect the number of generated Karman vortexes with good sensitivity under any severe conditions by inserting both tip parts of a rod member into two tubes and coupling them, and detecting the vibration of a detection body as the displacement of the rod member. CONSTITUTION:Both end parts of a tube body 4 whose tip parts are formed in a U shape are inserted into hole parts 3a and 3b bored in a flange 2. The rod member 5 formed by bending, for example, a metallic thin tube in a U shape are inserted into both the end parts of the tube body 4 and fixed from outside the flange 2. When fluid flows, the triangular column 12 of a sensor holder 10 becomes an obstacle to generate Karman vortexes behind it and the pressure of the Karman vortexes is applied to the tube body 4 in the holder 10 through a through hole 15 from alternate side. The tube body 4, therefore, vibrate at right angles to the flow direction in synchronism with the generation of the Karman vortexes. The frequency of the vibration is equal to the flow rate and transmitted to the member 5 with good sensitivity and transduced into the displacement of its peak part 5a, and the displacement is detected from variation in the reflection quantity, etc., of an optical fiber 8.

Title: Optical recording medium
Inventor: KAWAKAMI HARUO
IPC: G11B7/243
Filed: 1987-12-21
Abstract: PURPOSE:To increase the data transfer speed of an optical disk and to increase the number of repetitions of writing and rewriting by specifying the value of the right lower index of the average chemical compsn. Ge1-xBi2xTe2x+1 of an optical recording material layer sandwiched by cooling layers via protective layers. CONSTITUTION:The optical recording material layer 3 is spot-melted by laser light and thereafter, said layer is rapidly cooled to a non-crystalline state by either of the cooling layer 5 consisting of Al or the transparent cooling layer 7 via the protective layers 2, 4 consisting of SiO2, by which recording is executed, at the time of writing information to the optical disk constituted by covering the surface with the protective layer 6 consisting of an org. material and forming a substrate 1 of polycarbonate. The crystallization rate is increased and the erasing time of the recorded information is shortened and in turn, the rapid cooling is needed at the time of recording as compared to the case in which GeTe and Bi2Te3 are respectively along, if the compsn. of the layer 3 satisfies formula I. In addition, the viscosity of the material increases and the annihilation by evaporation at the time of spot melting is suppressed. The number of repetitions of the writing and erasing is thus increased.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus, for the detection of a moving object, in which the volume of the moving object such as a flying ink liquid drop or the like can be detected immediately together with its movement speed. SOLUTION: The time required when the shadow 2A of an ink liquid drop is moved to the second straight line part 4c from the first straight line part 4b of a light receiving element 4 is detected. The distance X between the first straight line part 4b and the second straight line part 4c is divided by the time in which the ink liquid drop is passed. The movement speed of the ink liquid drop is calculated. On the other hand, a relational expression which refers to the movement distance and the projection area of the ink liquid drop (the shadow 2A) between the first straight line part 4b and the second straight line part 4c is found. After that, it is differentiated so as to find a relational expression which refers to the movement distance and the radius of the ink liquid drop. The relational expression is turned and integrated symmetrically with respect to an axis.  The ink liquid drop is regarded as an axially symmetric rotating body regarding the central axis in its movement direction, and the volume of the ink liquid drop is calculated.
