Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To enable increase in the flying margin and realize lowering of the probability of interference between a magnetic head and a record medium by causing a recess portion to have a depth for housing therein a non-core width portion of a lower pole layer and a coil layer, and forming the recess portion near a core width portion of the lower pole layer by a groove having a depth for housing the core width portion of the lower pole layer. SOLUTION: A non-core width portion of a lower pole layer 52 and a coil layer 53 are housed in a recess portion 50a of a substrate 50, and a core width portion 52a of the lower pole layer 52 is housed in a groove forming the recess portion 50a of the substrate 50.

Abstract: PURPOSE:To adjust density so as to provide desired characteristics to a calcined ceramic compact, by immersing the green compact of an uncalcined ceramic material in a mercury bath, and measuring the buyancy applied to the green compact thereby preventing the dissolution of the green compact and measuring the accurate density. CONSTITUTION:If there is a need for adjusting the density of ceramics for O2 sensors, etc. accurately, a green compact of a ceramic material prior to calcining is immersed in a mercury bath and the buoyancy that the green compact receives is measured. For example, a table 3 of a measuring device is first brought down to the position of a stopper 14, and the green compact is placed on the tray provided in the end part of a balance pole 8 provided to an electronic balance 7. The weight of the green compact is measured from the numerical value displayed on the balance 7. A motor 12 is run by the signal from an operation box 15 to move the table 3 placed thereon with a sliding table 5 upward so that the green compact measured of the weight is forced into the mercury in a mercury tank 6 on the table 5 by the bottom surface of the tray mounted to the balance pole. The buoyancy applied on the green compact is measured by switching the balance 7 of the pole 8 to measurement of buoyancy. The density of the green compact is operated from the buoyancy and the weight of the green compact, whereby the density is known easily.

Abstract: PURPOSE:To clean an original platen if the platen is stained and to improve deteriorated picture quality in its early stage by performing abnormality processing once the presence of a non-change area is decided even after an original image changes. CONSTITUTION:An image processing system is provided with an LED array 4 which irradiates an original 3 with light and a CCD sensor 5 which detects the quantity of reflected light corresponding to the density of the original image. The sensor 5 decides whether or not there is the non-change area where an image signal stored in an image memory 34 has no change even after the original image changes. When the presence of the non-change area is decided, an image processing part 32 performs the abnormality processing such as the generation of a warning signal. Then, copying operation is prevented from being repeated in a deteriorated picture quality state without notifying the staining of the original platen 1. Then the stain is cleaned in its early stage and the deteriorated picture quality is improved fast.
