Title: Thin film magnetic head
Inventor: SHIIKI KAZUO
IPC: G11B5/31
Filed: 1983-03-30
Abstract: PURPOSE:To obtain a thin film magnetic head which can be used in a high frequency band of >=10MHz by providing notches in the end part of one magnetic pole pattern at least and allowing notches to face each other in parallel with the track breadthwise direction. CONSTITUTION:Notches are provided in the end part of one magnetic pole pattern, at least, of an upper magnetic pole 5 of a thin film magnetic head, and notches are allowed to face each other in parallel with the track breadthwise direction. This head is produced by changing a mask for magnetic pole pattern formation in the same process as a conventional head. When this head and an Fe2O3 recording medium are combined and the frequency dependence is measured at 40m/s relative speed, the frequency dependence is superior in high frequency characteristic as shown by a curve 20. It is guessed that the movement of a magnetic wall which is a cause of the degradation of the high frequency characteristic is prevented by notches. Consequently, the thin film magnetic head which can be used in the high frequency band of >=10MHz is obtained.

Title: Semiconductor device
Inventor: FURUIKE SUSUMU
IPC: H01L21/52
Filed: 1982-03-30
Abstract: PURPOSE:To prevent an adhesive agent from creeping up at the time of dies bonding by a method wherein a stepped part is provided on the plane supporting and glueing a semiconductor chip, which is then glued on top of the sepped part with the adhesive agent. CONSTITUTION:A projected stepped part 5 is provided on a support where a semiconductor chip 1 is glued thereto by means of dies bonding and that part is projected upwardly from the surface of the support in the form of tiers. If the chip 1 is glued to the stepped part 5 by applying silver paste, the silver paste 3 that has overflowed from the undersurface of the chip 1 will not creep up to the chip side 4 but flow on the surface of the support 2 along the side 6 of the stepped part 5 to the contrary. In this case, to obtain the satisfactory effect of preventing the silver paste from creeping up, the periphery of the surface of the chip 1 for bonding must be equal to or protruded from that of the stepped part 5. For this reason, the area of the top of the stepped part 5 is made roughly equal to the chip 1 surface to be glued.

Title: Chaos solution of traveling salesman problem
Inventor: SHONO KATSUFUSA
IPC: G06F17/18
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To quickly find a likely solution of a complicated combination problem such as a traveling salesman problem by utilizing a combination that is included in the time series of a chaos which is observed by nonlinear quantization. SOLUTION: When the internal state of a chaos is now written as y (t), the y (t) is a time series and (t) is a discrete time. The database of a time series Z (t)-1 which is nonlinearly quantized is retrieved, and the time series of a degenerate quantum is extracted and is rewritten in a data format that is suitable to a traveling salesman problem. For instance, there are 5!=120 ways in traveling combinations in the case that a traveling salesman starts from a city 0 and comes back to the city 0 again. Although a person easily finds the shortest distance by observing them with his eyes in the case of the combinations to this extent, an arrangement which rewrites the time series of Z (t-4) of a degenerated quantum to 0 to 15 is utilized.  That is, 0 is retrieved with the time series and cities 1 to 5 are found out among the sequence that follow 0 in a sequential order and are made a traveling route.
