Title: Production of ceramic superconductor
Inventor: HAYASHI KAZUHIKO
IPC: C04B35/00
Filed: 1989-09-09
Abstract: PURPOSE:To obtain a superconductor containing oriented crystals and having excellent strength and superconducting properties by solidifying a molten liquid and growing a crystal using a unidirectional solidification process while specifying the ratio of the temperature gradient of solid/liquid interface to the rate of crystal growth. CONSTITUTION:A ceramic superconductor is produced by solidifying a molten liquid using the following unidirectional solidification process. The crystal growth is carried out by solidifying the molten liquid under a condition satisfying the formula 1<=G/R<=50, wherein G(K/cm) is the temperature gradient of solid/liquid interface and R(mm/h) is the rate of crystal growth. It is necessary to suppress the formation of free crystal to inhibit the nucleation in order to improve the orientation of the crystal. When G/R<1, crystal orientation does not take place or the crystal growth becomes impossible. The grain size of the crystal is increased at G/R>50.

Abstract: PROBLEM TO BE SOLVED: To prevent occurrences of erroneous operation even when a small proportional valve is used, by stopping the operation of a closing means in the case where the calculated opening of a proportional valve is not less than a first given opening which is near the maximum opening. SOLUTION: When an operational switch 51 of an electric rice cooker is turned on, a control unit 5 determines an opening of a proportional valve 1 on the basis of the various kinds of parameters such as a detected temperature or the like from a temperature sensor 52 for detecting temperature of an inner pot.

IPC: B42C1/12
Filed: 1990-09-05
Abstract: PURPOSE:To improve the matching properties of a sheet bundle by allowing a sheet matching device to perform a matching action a specific number of times each time one piece of sheet which is fed by an image formation device is distributed to a distribution bin and further allowing the device to execute the matching action after a specified number of sheets are distributed to the distribution bin. CONSTITUTION:The first copy is discharged to ADF 111 from a main duplicator system 110 and the second copy is transported to a platen 118 of the main duplicator system 110, and set there. This process takes a comparatively long time and a fixed temporal interval occurs until the copy sheet of the second copy reaches a distribution bin 2. Therefore, a highly effective sheet matching action is performed taking advantage of this temporal interval. A command which enables a positioning member to perform a single matching action is output to a drive motor for a sheet matching device. At the same time, the copy sheet of the second copy is distributed and two matching actions are executed at low speed during a temporal interval between the arrivals of the second and the third copy. The sheet matching device is caused to perform a sheet matching action 'n' number of times each time one sheet is distributed to the distribution bin. In addition, the device is caused to perform the sheet matching action (n+1) or more number of times after a specified number of sheets are distributed to the distribution bin.
