Patent JP-H03192805-A (JP)
Title: Antenna system
Inventor: TSUNEKAWA KOICHI
IPC: H01Q13/08
Filed: 1989-12-22
Abstract: PURPOSE:To realize an antenna with high gain in spite of small size by increasing a dielectric constant of a 1st dielectric substance in existence between a ground plate and a part or all of radiation element surrounding parts while the thickness is made thinner toward the outward direction at the outer circumference of the radiation element more than the dielectric constant of the dielectric substance in existence between the ground plate and the radiation element other than the 1st dielectric substance. CONSTITUTION:The antenna system is provided with a 2nd dielectric substance 4 filling part other than a 1st dielectric substance between a radiation element and a ground plate and with the 1st dielectric substance 5a whose thickness is made continuously thinner from the surrounding part of the radiation element toward the outside of the radiation element. The dielectric constant of the dielectric substance 5a is selected higher than the dielectric constant of the 2nd dielectric substance 4. Since the radiation element of a microstrip antenna is made of a dielectric substance having a high dielectric constant in the radiation element, an electric field 6 coming from the radiation element 1a contributing to the radiation has a higher density than that of an electric field 7 caused at the inside of the radiation element 1a. Moreover, since the dielectric substance 5a is cut off obliquely from the circumference of the radiation element 1a, the electric field radiates along the cut face, the X direction component of the electric field 6 is strong and the gain is increased.

Title: Mr type magnetic head
Inventor: TADOKORO HISANO
IPC: G11B5/31
Filed: 1994-12-12
Abstract: PURPOSE: To provide an MR type magnetic head capable of stably maintaining the output of a magnetic recording signal by suppressing the increase of the resistance of low resistance layers at the time of heat treatment. CONSTITUTION: Low resistance layers 2, 2a, 2b are formed at prescribed positions on the top of the MR element layer 1 of an MR type magnetic head. Each of the layers 2, 2a, 2b has a three-layered structure formed by successively laminating a Ti layer 3, an NiFe layer 4 and a Ti layer 5. Even when heat treatment is carried out after the layers 2, 2a, 2b are formed, NiFe is not alloyed with Ti and the variation of the resistance by alloying is prevented. The variation of the resistance after heat treatment corresponds to the very slight variation of the resistance of NiFe itself and the rate of variation is made constant.

IPC: G06F19/00
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To drastically shorten the processing time for the simulation of a semiconductor by applying a statistical calculation technique. SOLUTION: At first, the distribution information including the distribution center value and the dispersion for each parameter is inputted or set (ST 1) and samplings are performed for at least two points of a distribution center point or the point which is away from the distribution center point by a prescribed distribution ratio (ST 2). Next, the characteristic value is calculated for each parameter at each sampling point (ST 3). As for the prescribed approximate term derived by extending the power-law average expression of the very small displacement of the characteristic of a semiconductor, the value is calculated by using the characteristic value (ST 5) and the dispersion or the standard deviation of the characteristic of the semiconductor when all the parameters are shacked is calculated from the calculated approximate term value (ST 6).  Preferably, the samplings are performed for the 2 to 4 points of the distribution center point, the two points which are away from this point to the both sides by the prescribed distribution ratio and further the two points which are away from each other by this distribution ratio. Thus, the distribution state of the characteristic can be easily estimated from the characteristic calculation results at several points. This simulation device has at least an output display means in addition to respective means performing the above-mentioned processings.
