Title: Flexible magnetic disk memory
Inventor: SHIMIZU ISAO
IPC: G11B25/04
Filed: 1984-04-02
Abstract: PURPOSE:To attain the use of all laminated disks by attaching the disks which have larger bending strength than the recording disks and can be bent toward the lamination of disks to those at both ends of those laminated recording disks with a space approximately equal to the lamination space of the recording disks. CONSTITUTION:Flexible recording disks 2 are laminated with equal pitches and held between end plates 3 to obtain a lamination matter 1 serving as a rotor. This matter 1 is fixed to a spindle 7 with a bolt 8 and revolved in a body with the spindle 7. A shift stage 4 set outside the matter 1 moves a blade 5 to which a magnetic head 6 is buried toward X and Y. The plates 3 are laminated with a space approximately equal to the lamination pitch of the disks 2 and have shapes having larger bending strength than the disk 2. Thus the disks 2 set close to the plates 3 can also be used as files. This increases the record capacity of this magnetic disk memory, then improves the using efficiency of a lamination disk.

Title: Method for predicting breakout in continuous casting installation
Inventor: IDEUE TOMOO
IPC: B22D11/20
Filed: 1982-04-19
Abstract: PURPOSE:To predict the outbreak of a breakout accident surely by measuring the relative speed between the mold of a continuous casting installation and a solidified shell with a magnetic speed detector and emitting an alarm when the detected value is zero. CONSTITUTION:A magnetic speed detector 4 is mounted to the wall of a mold 1 of a continuous casting installation to measure the relative speed between the mold 1 and a solidified shell 3. Since there is a relative speed in the stage of normal operation, an output is generated in the detector 4. When the shell 3 near the meniscus breaks out, the shell is divided to the shell 3a which is stuck on the wall of the mold 1 and the shell 3b which is not stuck thereon. The shell 3a loses the relative speed in such a state; thererfore, the signal of the detector 4 is nearly zero, then an alarm device 6 operates to predict the generation of the breakout.

Filed: 1994-03-31
Abstract: PURPOSE:To make it possible to scroll up a screen and to obtain a wide visual field angle without impairing the effectiveness of polarization characteristics by composing a polarizing sheet layer having the axis of polarization coaxial with the polarization direction of the projecting light of a liquid crystal projector from a specific uniaxially stretched polyester film. CONSTITUTION:This reflection type screen is composed, successively from the incident side (i.e., observer side), of a light diffusion sheet 1, a tacky adhesive or adhesive layer 2, a polarizing sheet 3, a tacky adhesive or adhesive layer 2, a light reflection ink layer 4 and a base material 5. The polarizing sheet 3 is formed by using the uniaxially stretched polyester film and, for example, a PET resin with which dyes are mixed, is made into a film form and this film is uniaxially stretched to orient the molecules in the prescribed direction and to adsorb the dyes, thereby the axis of polarization of the sheet is aligned to the axis of polarization of the projector. As a result, the degree of polarization is increased and, therefore, the screen is hardly torn even if the film thickness is decreaed. In addition, the film has moisture resistance and, therefore, the good scroll up of the screen is possible.
