Title: Magnetic head
Inventor: ISOZAKI MAKOTO
IPC: G11B5/115
Filed: 1984-04-17
Abstract: PURPOSE:To reduce a noise component induced from an erasure head to a write/ read head by making the vertical distance of the 2nd magnetic gap to a specific value so as to reduce the capability of the erasure head picking up a signal. CONSTITUTION:The width and length of the erasure gap 21 formed to the erasure head 22 are the same as those of a conventional technology and the distance L in the vertical direction to a recording medium K is >=100mum and it is larger than the distance of the conventional technology. Furthermore, as to an R/W head gap 2, it is the same size as that of the conventional technology. Thus, the width of the erasure gap 21 relates to the ability forming the write, that is, the erasure band of the erasure head 7, and the vertical distance L7 depends on the pickup capability of the signal, and when the distance L7 is taken larger, the capability picking up the signal unnecessary signal for the erasure head 7 is decreased, resulting that the noise component induced to the write/read head 1 is decreased.

IPC: H01L21/60
Filed: 1985-04-11
Abstract: PURPOSE:To obtain a compact, high-density structure, by avoiding the common use of a wiring conductor, and arranging and bonding the active surfaces of an IC so as to face each other. CONSTITUTION:The common use of a wiring conductor is not provided. The active surfaces of an IC are arranged and bonded so as to face each other. As materials for a bump, mainly gold, solder and the like are used. As a circuit base material 5, polyimide, glass fiber-reinforced epoxy and the like are used. There are the following various patterns and methods in mounting. After one side of first ICs 1 and 2 and second IC 1' and 2' are gang-bonded, the second IC 1' is mounted in the face-down attitude. Or both ICs are mounted simultaneously in the face-down attitude. Thus the mounting area can be reduced, and the high density mounting can be carried out.

Title: On-line measurement of collective texture
Inventor: KITAGAWA TAKESHI
IPC: B21B37/00
Filed: 1979-06-19
Abstract: PURPOSE:To permit an on-line measurement of steel plates or the like to be ready by applying a characteristic X-ray in parallel beams to a rolled metal plate by operating a X-ray source over a range of a fixed angle, and detecting the diffracted X- ray by means of a position-sensitive detector, in order to measure density distribution. CONSTITUTION:A characteristic X-ray in parallel beams is applied to the area on a rolled metal plate 7 by operating a X-ray source 1-1 over a range of a fixed angle, and the diffracted X-ray from the rolled plate 7 is detected by means of a position- sensitive X-ray detector 1-3 arranged along a circular arc. The intensity of the diffracted X-ray from each crystal face obtained by the wave-form analysis of the diffracted X-ray is compared with the random intensity obtained from a random orientation crystal face, in order to measure the axial density distribution parallel to the normal direction of the rolled plate 7. The axial density of each crystal lattice face is calculated by, for example, by operating the X-ray tube 1-1 in a head 1 by a traverse drive controller 4 and an X-ray generator 2, and transmitting signals from the detector 1-3 to an electronic computer 5 through a controller 3, in which a fixed operation is processed.

Title: Magnetic recording and reproducing device
Inventor: KANEKAWA HIROSHI
IPC: G11B5/588
Filed: 1990-03-27
Abstract: PURPOSE:To prevent overlap of recording tracks by performing the feedback control of an actuator abased on information of the magnetic field detected by each magnetic head so that the difference between respective heads is a prescribed extent. CONSTITUTION:A mobile head 16 detects magnetic fields Bf1 and Bf2 generated by AC magnetic field generating coils 45 and 45a to output a detection signal each time when passing the vicinity of an AC magnetic field generator 40. A BPF 42 allows a signal component S having a frequency F1 to pass through, and a BPF 43 allows a signal component T having a frequency f2 to pass through. A subtractor 44 operates the difference between two components S and T and feeds back this difference component to an actuator 7, and the mobile head 16 is moved in such direction that this difference is zero. Thus, the mobile head is positioned to a prescribed position independently of the hysteresis, the temperature characteristic, the secular change, or the like of the actuator 17.

Abstract: PURPOSE:To simplify operation by press-fitting a 1st pressure fitting roller to a 1st driving roller at the time when a machine score reaches the blade vicinity, and pulling and breaking a continuous form by the peripheral speed difference of 1st and 2nd driving rollers. CONSTITUTION:A form 5 is transferred by biting with a pinned belt 11, specific printing and line feed are performed by a printing head 12 and when the tip of the form is approached to a 1st driving roller 16, a 1st pressure fitting roller 3 is separated by turning OFF a solenoid 2. A form feeding quantity then becomes in a specific amount and when a machine score reaches just under a blade 6, the solenoid 2 is turned ON to press-fit a 1st pressure fitting roller 3 to a 1st driving roller 16, the form 5 is pulled and strained by the difference in the peripheral speeds of a 2nd pressure fitting roller 9 and 2nd driving roller 15, pressed to the blade 6 and the form 5 is broken from the machine score. Thus the distance between both driving rollers can be shortened and a device can be miniaturized, and the simplification of the operation is enabled only by changing an input setting even if the intervals of the machine scores differ.

Filed: 1990-03-27
Abstract: PURPOSE:To prevent erroneous printing by reading a format code of a slip inserted into a printer device by an optical character reader, and comparing it with a format printed by an application program which is being executed by a computer main body. CONSTITUTION:When a slip 9 is inserted, a printer device 1 reads a slip format code 10 through an optical character reader 2 before printing is executed, and the code which is read is transferred to a recognized slip format code store area 5 through a printer signal line 8.
