Title: Single crystal growing apparatus
Inventor: SUZUKI TOSHIHIKO
IPC: H01L21/208
Filed: 1992-05-29
Abstract: PURPOSE:To obtain a single crystal having little crystal defects at high growth speed by forming a temperature distribution of the surface region of a molten liquid in such a manner as to lower the temperature from the part contacting with a crucible toward the center using a selective heating means and a heat- shielding means. CONSTITUTION:A single crystal 6 is pulled up and grown while applying a magnetic field to a molten liquid 3 by an electromagnet 21 surrounding a water- cooling jacket 10a. The molten liquid 3 having electrical conductivity is subjected to an electromagnetic force by the magnetic field and, as a result, the thermal convection is suppressed. Since the temperature distribution caused by a heater 4 is precisely reflected to the temperature distribution of the molten liquid 3, the temperature becomes low at the center of the molten liquid and high at the circumferential part and, at the same time, the temperature difference becomes large between the center of the molten liquid 3 and the part contacting with the liquid surface of the molten liquid and the inner wall of the crucible 2. Accordingly, the growing speed of the single crystal 6 can be increased compared with the case free from the applied magnetic field.

Title: Method and apparatus for strengthening welded part of ink ribbon
Inventor: MINOKE TAKAHARU
IPC: B41J33/10
Filed: 1985-07-26
Abstract: PURPOSE:To strengthen a welded joint in forming a loop form ink ribbon and prevent yarns from being frayed at the joint part, by disposing a heating element in proximity to an end part of the welded joint of the ink ribbon, and melting the end part by radiant heat from the heating element. CONSTITUTION:When strengthening the welded part 22 of an ink ribbon 21, a heating element 23 is disposed in proximity to an end part of the welded joint, and the end part is melted by the radiant heat from the heating element 23. By this, the end part of the selvage of the welded part 22 is made integral with the main body of the ribbon, and the welded part is strengthened. Because the heating element 23 does not make contact with a welded joint, it is unnecessary to clean the heating element 23, and flashes are not generated. heat- radiating plates 25, 26 effectively diffuse heat from the heating element 23, thereby protect parts of the ink ribbon other than the welded part.

IPC: B41M5/382
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To make the thickness of a photothermal conversion layer nearly agree with a peak position of a temperature distribution in a thicknesswise direction of the photothermal conversion layer by adjusting the thickness of the photothermal layer so that a distance from a maximum temperature position in the thicknesswise direction of the photothermal conversion layer to a toner layer coincides with a position in a specific range of the thickness of the photothermal conversion layer. SOLUTION: A photothermal conversion layer and a toner layer are set on a supporting body, thereby forming a toner sheet. A thickness of the photothermal conversion layer is adjusted so that a distance from a maximum temperature position in a thicknesswise direction of the photothermal conversion layer to the toner layer coincides with a position of 0-1/3 the thickness of the photothermal conversion layer. The toner sheet and an image-receiving sheet having an image-receiving layer set on a supporting body are overlapped to make the toner layer and the image-receiving layer opposed to each other. The toner layer is transferred onto the image-receiving layer by irradiating a laser light. The toner sheet is separated from the image-receiving sheet. Images are thus formed.  The photothermal conversion layer is prevented from swelling and favorable recording without a density decrease can be carried out.
