Title: Method for relief printing of image line or pattern on ceramic product by screen printing
Inventor: ISATO NOBUKATSU
IPC: B41M1/12
Filed: 1988-03-29
Abstract: PURPOSE:To form a three-dimensional pattern on a ceramic product by adhering a photosensitive film to a layer of a photosensitive agent applied to a screen and by removing only the unexposed image or pattern part by spraying with water for development. CONSTITUTION:A photosensitive film is adhered to a layer of a photosensitive agent applied to a screen to increase the strength of the layer. Accordingly, the strength of the exposed part is increased and only the unexposed part is removed even in the same mesh by spraying with water for development to obtain a screen printing plate having a clear image or pattern. When the printing plate is used, a thick,clear relief image line or pattern is formed on a ceramic product by the total of the large thickness of the screen gauze and the thickness of the photosensitive film.

Title: Method and apparatus for immersion freezing
Inventor: ENDOU TAKAO
IPC: A23L3/36
Filed: 1982-05-06
Abstract: PURPOSE:To enable the smooth flow of the material to be frozen in the immersion freezing apparatus, and to carry out the immersion freezing of the material in high efficiency, without damaging the material, by taking advantage of the specific gravity difference between the freezing medium and the material to be frozen before and after the freezing operation. CONSTITUTION:The material to be frozen (e.g. fish, vegetable, processed food, etc.) is frozen in a low temperature immersion liquid having a specific gravity between that of the material before freezing and after freezing (the frozen material has smaller specific gravity). The immersion liquid is, e.g. an aqueous solution of ethanol containing proper amount (<= about 10% concentration) of salt. The material is thrown into the freezing tank 1 containing said low temperature immersion liquid by the conveyor 6, allowed to sink in the falling tank 2, and transferred through the connecting path 4 to the floating tank 3. When the specific gravity of the material is decreased by the progress of freezing, the floated frozen material is transferred through the delivery conveyor 9 and the mesh plate 20 and collected in the storage pallet 22. The separated immersion liquid is recycled to the falling tank 2 through the filter 12, the recovery tank 11, the cooler 17 and the injection header 19.

Title: Converter of magnification ratio of variable magnification copying machine
Inventor: OOTA JIYUNICHI
IPC: G03B27/34
Filed: 1981-05-20
Abstract: PURPOSE:To simplify the mechanism of the titled converter, by using the same wrapping transmission mechanism for both the scanning of an original and the conversion of magnification ratio and displacing the reflecting systems at the subject side and the image side respectively. CONSTITUTION:When the magnification ratio is chaned, a scanning motive  power source M1 is stopped with a magnification ratio converting motive power source M2 set active respectively. At the same time, the clutch between a pulley 18 and a sprocket 19 is turned off, and the clutch between a pulley 16 and a sprocket 22 is turned on. When a magnificaion ratio is increased, the source M2 turns a sprocket 23 clockwise. This rotation of the sprocket 23 is transmitted to the sprockets 22 and 24, and then a pinion 27 also has the clockwise turning. Then a Dach mirror 5 at the image side has a displacement to the left. On the other hand, the pulley 16 turns clockwise by the rotation of the sprocket 22. Thus the motive power is conveyed to a wire 33, and a mobile pulley 13 tuns counterclockwise to move to the right. In this case, a plane mirror 2 has no movement to realize a magnifying optical arrangement.
