Title: Oxide superconductive wire material and manufacture thereof
Inventor: TAKEDA YUKIO
IPC: H01B12/06
Filed: 1987-06-26
Abstract: PURPOSE:To obtain a wire material of a high Tc (critical temperature) and of flexibility by sticking and firing an oxide superconductive layer around thin ceramic fibers having heat resistance, oxidation resistance, and flexibility. CONSTITUTION:Oxide superconductive powder and organic binder are mixed to make slurry. Ceramic fibers are passed through the slurry to make the slurry of oxide superconductor stick around the ceramic fibers. The material is then heated to decompose the organic binder contained in the slurry and is further heated in the ambient atmosphere or in an oxygen atmosphere up to a temperature at which the oxide superconductive powder is sintered to obtain a wire material with the oxide superconductive layer formed around the ceramic fibers. This makes it possible to easily obtain the wire material having flexibility to some extent, a high Tc, and no electric resistance.

Abstract: PURPOSE:To improve maintainability of a blade part where cleaning work is hard by forming blades detachably attached to a body, with combustible material. CONSTITUTION:A ventilation fan 1 is constituted by forming blades 3 detachably attached to a body 2, with combustible material. Namely, for example the blade 3 is so made that corrugated cardboard is pressed and formed in a designated shape and then its surface is painted.

An intersection calculation means 3 finds the crossing area of a line of sight decided by a given visual point and each basic shape of each quadratic surface of each image element on a screen desired to display. A set operating means 4 performs the set operation between the crossing areas at every shape of obtained quadratic surfaces, and finds a visible point that is a point on the boundary surface of three- dimensional shape. A luminance calculation means 5 finds the luminance of an obtained visible point. And the picture is displayed on a graphic display 9 as the one of three-dimensional shape in which all the boundary surfaces are formed in the quadratic surfaces.

IPC: G06T5/20
Filed: 1994-07-11
Abstract: PURPOSE:To realize signal processing at a higher frequency than a sampling frequency of a video signal while keeping synchronization between an input and an output. CONSTITUTION:Frame memories 2, 4 are arranged respectively to an input and an output of a processor 3. An input side controller 10 detects a synchronizing signal from a video signal to update a write address 14 of the input side frame memory 2 according to the detected synchronizing signal. An output side memory controller 13 updates a read address 15 of the output side frame memory 4 synchronously with a timing signal 16 from the input side memory controller 10. The processor 3 processes picture element data in the input side frame memory 2 at a higher operating frequency than a sampling frequency in the video signal independently of the synchronizing signal and stores the result to the output side frame memory 4.

Title: Position detector
Inventor: TAMARU EIJI
IPC: G06F3/047
Filed: 1983-08-30
Abstract: PURPOSE:To secure a high level of resolution with position detection despite a large distance set between thin strip conductors, by obtaining different levels of position detection outputs between a push of a point on a thin strip conductor and a push of a point between said strip conductor and its another adjacent thin linear conductor. CONSTITUTION:When a position Q on a thin strip conductor L5 of a position detecting part 1 is pushed, a switch S5 is turned on and grounded. As a result, the level of voltage (d) varies in a period ''0'' while the S5 is kept on and multivibrators 12 and 15 are triggered by the fall and rise of the voltage (d). Thus output (e) and (e') are obtained and supplied to counters 9 and 14 respectively. The count value 5 of pulse signals (a) is supplied to a compounding circuit 16 from the counter 9. While the count value 6 of signals (a) is obtained from the counter 14 and supplied to the circuit 16. The circuit 16 obtains the average value 5.5 of both values 5 and 6. When a position Q' between thin strip conductors L5 and L6 is pushed, the average value 6 is obtained in the same way. Thus it is possible to obtain the average value data in response to the pushed position varying every 1/2 distance between thin strip conductors.
