Title: Image forming device
Inventor: NISHIMURA KATSUHIKO
IPC: G03G15/09
Filed: 1988-09-09
Abstract: PURPOSE:To prevent the deterioration of durable density and to obtain an image having high image quality by forming a covering layer having grains or a lump of rains which are at least rougher than the minimum surface roughness of a developer carrier on the surface of the developer carrier and also having conductivity. CONSTITUTION:The developer carrier 14 consists of a conductive developer carrying member 17 and the covering layer 18, and the layer 18 consisting of the grains or the lump of grains which are rougher than the minimum surface roughness of the member 17 is formed. In the case that the member 17 is produced by extracting and processing aluminium, the surface roughness is within the range of 0.8s-10s. Therefore, it is desirable that the grain or the lump of grains forming the layer 18 has the average grain diameter of 1.0mum-9.0mum. By providing the covering layer 18, reflection force acting between the fine powdered toner positioned near the surface of the developer carrier and the developer carrier is eliminated or reduced and the occurrence of blotch, void or sleeve ghost is avoided. Thus, the image having high image quality can be obtained.

Title: Digital signal magnetic recording and reproducing device
Inventor: MATSUDA TOYOHIKO
IPC: G11B5/09
Filed: 1988-09-08
Abstract: PURPOSE:To lower a bit error rate by the distortion of an electromagnetic conversion system by setting the threshold value of a decoder at a level where the distances from adjacent signal points on a signal arrangement drawing are substantially equal. CONSTITUTION:In a decoder 18 to convert the quaternary signals of the two systems of LPFs 16 and 17 into a digital signal, its threshold value is not fixed as before and a threshold value table is stored beforehand in a prescribed ROM so that the threshold value can be adjusted. The decoder 18 sets the threshold value at the level where the distances from the adjacent signal points on the signal arrangement drawing are substantially equal. Therefore, since the threshold value fit for the distortion can be set for the distortion of the electromagnetic conversion system, the bit error rate can be made lower than the decoding of a fixed threshold value.

Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To improve the safety of a worker during its execution by laminating respectively a front side sheet layer and rear side sheet layer consisting of nonwoven fabric on the front surface and rear surface of a base material sheet layer consisting mainly of rubberized asphalt, and allowing a unit mass ratio and expansion rate ratio of both sheet layers to satisfy a specific inequality. SOLUTION: A front side sheet layer A and a rear side sheet layer B respectively consisting of nonwoven fabric are layered on the front surface and rear surface of a base material sheet 1 layer consisting mainly of rubberized asphalt. The unit mass ratio and expansion rate ratio of both sheet layer A, B is permitted to meet an inequality of the unit mass ratio : front side sheet layer A > rear side sheet layer B, the expansion rate ratio : front side sheet layer A< rear side sheet layer B. As a result, even in the event where the surface of the water prevention sheet wets during its execution, if the worker walks on the sheet, slippage never takes place because the nonwoven fabric of the front side sheet layer A forming the front side absorbs little moisture, resulting in an improvement of the safety.
