Title: Image reader
Inventor: KAMEYAMA KENJI
IPC: G06T1/00
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To surely and accurately detect white reference data from a white roller for a long period. SOLUTION: When there is no large fluctuation in an output waveform of white reference data that is read from a white roller 10 by a contact type sensor 7, a control operating means (CPU) sets a white reference based on the white reference data. However, when an abnormal wave form exists in the output waveform of the white reference data, it makes the sensor 7 read white reference data for the roller 10 again by rotating the roller 10 a little. It enables the setting of appropriate white reference by repeating that until an abnormal waveform of reading of white reference data is eliminated and reading white reference data from a part that is different from the part of the roller 10 which previously performs reading.

Title: Horizontal continuous casting method
Inventor: KODAMA HIROSHI
IPC: B22D11/04
Filed: 1981-06-22
Abstract: PURPOSE:To prevent the condensation of the moisture in waste gases on the inside surfaces of molds and to prevent the leakage of molten metal by connecting a tundish to the molds via a metallic foil. CONSTITUTION:Prior to preheating of a tundish 1, it is connected by placing a metallic foil 5 (for example, a stainless steel foil of SUS 304 or the like, an aluminum foil) between the refractories 2 of a tundish nozzle and the connecting refractories 3 on a mold 4 side, after which the tundish 1 is preheated, and the preheating is finished just prior to casting. When charging of molten metal is started after this, there are no noises by steam generation and leakage of molten metal owing to cracking of the refractories 3 at all and the temp. of the molten metal in the tundish remains high during casting. Thus, the preheating time and  the time for preparation of casting are reduced.

Title: Manufacture of incandescent bulb
Inventor: KURODA TOMOAKI
IPC: C03B23/045
Filed: 1990-04-16
Abstract: PURPOSE:To enhance the yield from production by measuring the outside dia. of a glass tube at the fore stage of a pinch seal process, deciding the heating time depending upon the result from measurement, and thereby maintaining stable sealing conditions despite dispersion in the outside dias. of glass tube. CONSTITUTION:The outside dia. of the part of glass tube to be pinch sealed is measured by a glass tube outside dia. measuring machine 4. This machine 4 is for ex. a laser micrometer capable of simultaneously measuring the X- and Y-axis contactlessly, and the mean value of the measurements in the X and Y directions is adopted as outside dia. After measurement of the outside dia., pinch seal is made by a pinch seal machine 5. The heating time with a burner is varied depending upon the result from measuring the pressure contact sealing part outside dia. of the glass tube. This makes the heating time approx. constant regardless of varying wall thickness being proportional to the outside dia. of the glass tube, and stable sealing conditions can be maintained to lead to decrease of defects such as cracks and enhancement of the yield.
