Title: Digital recording material printer
Inventor: KUREMATSU MASAYUKI
IPC: G03B27/73
Filed: 2000-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a digital recording material printer capable of very inexpensively forming an image of high image quality with digital image light. SOLUTION: By rearranging or shifting two-dimensional digital image light based on a single exposure from a light source 1 by a mirror 7 so that the number of pixels may be increased in one direction, the wide image is formed on the recording material 8, besides, by exposing with digital image light plural times, the large-sized image is formed, then, even in the case the number of pixels based on the single exposure is small, the image of high image quality is formed by increasing the number of dots per 2.54 cm (1 inch).

Title: Refrigerator/freezer
Inventor: HIRAOKA TOSHIE
IPC: F25D17/08
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To preserver food while suppressing degradation by providing a storage compartment, i.e., a new temperature zone freezing compartment, having a temperature zone lower than a maximum ice crystal generation zone but higher than the freezing temperature zone, thereby prolonging the preservation period of food as compared with an ice temperature compartment. SOLUTION: Relationship between the preservation temperature and the reaction rate, i.e., the extent (met-myoglobin-ization) of variation in the surface color of food, is shown. The ordinate shows the reaction rate of met-myoglobin-ization and the abscissa shows the preservation temperature of food. The reaction rate of met- myoglobin-ization is highest in the maximum crystal generation zone from -1 deg.C to -5 deg.C where moisture in the food begins to freeze and an unstable state easily causing degradation of feed is brought about and the surface color is degraded. In other words, cells of the food are damaged and the taste is degraded. In order to preserve a food while avoiding the maximum crystal generation zone, temperature of a new temperature zone freezing zone freezing compartment is set at -5 deg.C or below.  Since a long time is required for thawing in the freezing temperature zone (-18 deg.C or below) although the preservation time is long, the temperature is set at -15 deg.C or above in order to preserve food while avoiding the freezing temperature.

Abstract: PROBLEM TO BE SOLVED: To provide a heat development device which prevents the occurrence of distortion on the surfaces of photosensitive heat developable sheets after heat development by preventing the adhesion of materials, such as photosensitive layer compounding agents, from the photosensitive heat developable sheets on transporting rollers, guides, etc., in bringing the photosensitive heat developable sheets into tight contact with heating members and heating the sheets, then separating the sheets and transporting the sheets in a discharge direction. SOLUTION: This heat development device heats films F including bases and photosensitive layers by the rotating heating member 14 in the state of bringing the films into substantial tight contact with the member in order to heat develop the films F, separates the films F from the heating member and transports the films. A roller pair 404 which comes into tight contact with the films F is disposed in order to transport the films F after the separation of the films from the heating member and at least the rollers on the photosensitive layer side of the films F are composed of thermally insulating elastic rollers. The roller pair is arranged in the regions where the temperature of the films F is the glass transition temperature of the bases or near the same.  The thermally insulating elastic rollers are composed of thermally insulating materials having thermal conductivity of <=0.3 W/(m.K) [at 300 K], a void volume of 50 to 80% and hardness of 30 to 70 deg. (JISA).

IPC: B41J29/00
Filed: 2000-03-14
Abstract: PROBLEM TO BE SOLVED: To reduce a printer in size and height and to prevent the occurrence of unnecessary high frequency noise. SOLUTION: An arch-shaped part of a U-shaped path of a feeding path of a recording paper is formed of an external U-shaped guide and an inner U-shaped guide. Each of the U-shaped guides is made of a metallic material and the recording paper is fed along the arch-shaped curved face. An organic coating material is coated on the face for feeding the recording paper so that the coefficient of sliding friction is small. As a result, it is possible to make a radius of curvature at the arch-shaped part small and to reduce the printer in size. A control board 81 for controlling the printer is accommodated in a space enclosed by a lower case 111 made of a metallic material and the U-shaped guides and a power board 82 is accommodated in a space enclosed by upper and lower cases 110, 111 and the U-shaped guides.  The U-shaped guide 11, boards 81, 82 and the upper and lower cases 110, 111 each made of a metallic material are grounded so that a shield effect for the boards 81, 82 with respect to unnecessary radiation is enhanced.
