Title: Coreless motor and lead
Inventor: SAWADA TAKESHI
IPC: H02K3/26
Filed: 1988-04-04
Abstract: PURPOSE:To prevent a magnetic path length from becoming long and the area of crossing magnetic fluxes from being narrowed by composing leads of a metal board and a thin superconducting film. CONSTITUTION:A rotor 8 is formed by obliquely winding leads 2 as an armature winding in a cylindrical state, and fixing it with epoxy resin. On the other hand, a permanent magnet 4 is disposed as a stator field inside the rotor 8. Here, leads 9 are formed of a metal board 13 formed of a conductor, and a thin superconducting film 10 in which one or more layers of rare earth metal or transition metal are deposited on one side face of the board 13. Thus, the magnetic flux which passes the current path formed of the leads is scarcely affected by the influence of Meissner effect to prevent the magnetic path length from becoming long and the area of crossing magnetic fluxes from being narrowed.

Title: Signal delay circuit
Inventor: KAMATA KAZUO
IPC: H03H7/30
Filed: 1978-07-05
Abstract: PURPOSE: To delay input signals with a good S/N by mixing and delaying a control signal, which is modulated according to the level, etc., of input signals, and input signals which are made into a fixed level.  
     CONSTITUTION: The level of input signals is detected by level detection circuit 2, and a control signal which has the amplitude modulated according to the level of input signals is generated from voltage control amplifier 4 where output signals of carrier generation source 5 are applied. Input signals which are made into a prescribed level by voltage control amplifier 1 controlled by this control signal are mixed with modulation control signals, which are outputted from amplifier 4, through HPF 3 by mixer circuit 6, and these mixed signals are delayed by multistage bucket brigade device (BBC) 4. In this case, since input signals applied to device 4 are adjusted into a fixed level, S/N is not degraded even if small-level input signals are subjected to a long-time delay. As a result, when the delay output of element 4 is separated by HPF 8 and BFP 9 to adjust the level of delay input signals to the same level as an input time through voltage control amplifier 10, delay input signals with a good S/N can be obtained.

Abstract: PROBLEM TO BE SOLVED: To enable the conservation of labor, the conservation of the space of an arranging place and inexpensive production by taking the image of the whole of the inner surface of a container and discriminating the contamination of the inner surface of the container on the basis of the obtained signal. SOLUTION: The light from a light source is applied to a paper cup 2 to be inspected through the optical fiber supported at a fixed position by a support 12 and the reflected light is imaged by a CCD image sensor 16 through a wide- angle lens 14 and the taken image is transmitted to an image processor 20 and a part other than an inspection part (e.g; edge part having possiblity judged to be contaminated) is subjected to image processing and a mask is applied to form an inspection image. An image is calculated by adding the standard image sample preliminarily stored in a memory and the inspection image. As a result, the light and shade of the image are set off to form an image having a constant hue.  Since a change appears on the image if there is a part different from a standard image in the taken image, the change is judged to be a flaw (contamination, molding inferiority) to output a signal.

Abstract: PURPOSE:To obtain a flux having excellent property efficiently with low energy consumption by pouring fused flux successively at a specified thickness on two or more sets, upper and lower, of cooling rolls and allowing it to cool and solidify in thin platy form. CONSTITUTION:Fused flux 3 is poured on upper rolls 8a, 8b through a ladle 1, tundish 2 etc. and cooled. Here, the flux is sent out as a semi-solidified body <=5mm. in thickness t1, and the gap hangs down on P' of 9a, one of lower rolls which does not coincide with that of upper rolls on a vertical line. The semi-solidified body 5 is further quenched on the outer circumference 5cm in length up to a point Qa, and sent out as a thin platy body 6 of <=3mm. and <=0.9 t1 in the thickness t2 in the lower  rolls 9a, 9b. This is broken by thermal stress and becomes flaky flux 6'. In case of  5mm.<t1, the cooling rate is small and crystals are easy to generate and the quantity  of duffusible hydrogen becomes great. In case of 3mm.<t2, heat radiation effect is  small and when 0.9t1<t2, contact with the rolls becomes insufficient and causes  increase of water and crystallization and crushing becomes difficult.
