Title: Coating quantity measurement apparatus and coating apparatus
Inventor: FURUKAWA TOMOYUKI
IPC: B05D1/28
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To precisely detect whether a proper amount of a coating material or an adhesive is applied to all of the products or not. SOLUTION: The weight of a coating apparatus before the coating treatment and the weight of a coating apparatus after the coating treatment are measured and from the weight difference before and after the treatment, the amount of a coating material applied is calculated as the value equivalent to the decreased weight. The coating apparatus itself is immovable and the evaporation of the coating material packed in the coating apparatus hardly takes place, so that the weight measurement is much easier and much more precise in the case of woody plates.

Title: Recording medium defect position information recording system
Inventor: SUGAYA SEIICHI
IPC: G11B20/10
Filed: 1986-09-19
Abstract: PURPOSE:To correctly record all pieces of the position information of a recording medium part in which a defect exists by registering the position information of an already allotted alternating area to a defective list as the substitute of the position information of the recording medium part. CONSTITUTION:When a defect is detected at a recording medium part (b) of a primary area 11 of recording medium, a controller reads the alternating allotting processing information of a recording medium part (b) before a new alternating allotting processing is executed to the recording medium part (b). An unused alternating area b' in an alternating area part 12 is retrieved, an alternating allotting processing is executed and the position information of a defect recording medium part (b) is stored to a data storing area B in a defective list 13. When the already allotted alternating area information is detected in a defective alternating processing information, the position information of an already allotted alternating area b' is stored into a data area B' in the defective list 13 as the substitute of the position information of defect recording medium. Thus, the position information of an alternating area, in which the defect actually exists, is correctly recorded and the maintenance of the recording medium can be executed further without fail.
