Title: Gap width measuring method of magnetic head
Inventor: SUENAGA TADATOSHI
IPC: G01B7/02
Filed: 1983-09-30
Abstract: PURPOSE:To measure the gap width of a sample head by making use of the edge effect of a magnetic flux to read the leakage magnetic flux of an artificial head with a magnetic head and obtaining the maximum output value from the read output of said leakage magnetic flux and the variable distance of the gap width of the artificial head. CONSTITUTION:A signal generation drive circuit 5 is connected to a coil 4 of an artificial head 1 having a gap 2. The gap 2 is reinforced with a nonmagnetic reinforcing member 6, and micrometers 7 are set at both ends of the member 6 to vary the width of the gap 2. In addition, a reflector 9 of a laser measurement device 8 is attached at the end face of the member 6. A contact is secured between the surfaces of the member 6 and a sample head 10. In this case, the width of the gap 2 is set larger than that of a gap 11 of the head 10. A contact is secured between the surfaces of both heads 1 and 10. A magnetic signal is always applied to the head 1 to move an edge G1, and the device 8 detects a position X1 of the G1 where the output signal of a coil 12 is maximum. Then an edge G2 is shifted in the direction (x) to detect a position X2 where signal outputs of both ends of the coil 12 are maximum. Thus the gap width of the head 10 is obtained from ¦x1-x2¦.

Title: Semiconductor memory device
Inventor: MIWA HITOSHI
IPC: G11C11/56
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To sharpen the scatter of threshold values and to stabilize the operation in low voltages by executing rewriting after a weak erase operation for a memory cell having a threshold value lower than the reading level and higher than the verify level. SOLUTION: The memory cell array 12 is stored with the threshold values corresponding to the data of four values, '11', '10', '01', '00'. For example, in the refresh operation for the data '01', a short pulse under 3.7 V of reading level for the data '01' is impressed as a weak erase pulse to shift the threshold of the memory cell to a higher side. Reading is carried out at the reading level of 3.7 V for the data '01'; the data held in a sense latch 13 is inverted and a verify operation is performed at the verify voltage of 3.5 V. As the result, the data held in the sense latch 13 conducts rewriting for the cell of '1'.

In addition, if the set value is corrected, a new set value is stored unless the counter 6 counted up a specified confirmation time(t). After the specified confirmation time(t) is elapsed, the stored set value at that time is stored as a final data. Accordingly, even if the code switch 1 is erroneously moved, this is not accepted and an automatic ignition is carried out in response to a set value presently stored.

Title: Image forming device
Inventor: UCHIDA TAKAYUKI
IPC: G03B27/02
Filed: 1994-07-14
Abstract: PURPOSE:To always stably obtain a good-quality image by widening a space between respective belt members existing in a range abutting on a transparent cylinder so that it may become wider as going from the upstream side to the downstream side in its traveling direction. CONSTITUTION:A carrying belt 13 is constituted of plural belt members. Between the belt members, a spacer roller 30 is provided in a roller 11 and a spacer roller 31 is disposed in a guide roller 12 arranged on the downstream side from a part where the belt 13 abuts on the cylinder 5, so that the belt members are separated from each other by the roller 31. Even in the case of supplying a sheet which becomes wavy in a high humidity environment, action for developing the sheet to both side edges acts on the sheet at an exposing part where the sheet is held between the cylinder 5 and the belt 13, so that air accumulation formed by waviness is squeezed to be reliesed toward both side edges of the sheet, thereby preventing 'lifting blurring'. Since the trailing edge of the sheet is also developed toward both side edges, 'wrikling blurring' is prevented.
