Patent JP-S58115623-A (JP)
Title: Magnetoresistance effect type head
Inventor: HORIBATA SHINJI
IPC: G11B5/39
Filed: 1981-12-28
Abstract: PURPOSE:To improve reproduction efficiency by arranging an insulating layer which is  thinner than an insulating layer between magnetic shielding bodies for clamping a  magnetoresistance effect thin film on the opposite end surface to the facing surface of  the magnetoresistance effect thin film with a magnetic recording carrier, and reducing  the magnetic resistance between the magnetoresistance effect thin film and a ferromagnetic material and thus increasing the amount of signal magnetic flux piercing the  magnetoresistance effect thin film. CONSTITUTION:The ferromagnetic material 10 made of a nonconductive ferromagnetic  material such as ferrite adhered onto a magnetic shield layer 3 by vapor sputtering  has a step 10a on the side where it faces the magnetic recording carrier 1, and an  insulating layer 4, magnetoresistance effect element 5, insulating layer 6, and magnetic  shield layer 7 are adhered thereupon successively. The adhered insulating layer 4 is  thinned at the step part to allow the rear edge B of the thin film 5 and the ferromagnetic material 10 to come much closer, and consequently they are considered nearly to short-circuit magnetically, decreasing the magnetic resistance between the thin film 5  and ferromagnetic material 10. Therefore, almost all of signal magnetic flux entering  the thin film 5 at a part A reachs a part B and pierces the ferromagnetic material 10  and magnetic shield layers 3 and 7, so the leakage of magnetic flux to the magnetic shield layers before the part B is reduced.

Inventor: MISHIMA AKIRA
IPC: H01F37/00
Filed: 1984-10-17
Abstract: PURPOSE:To form the gapped core type reactor of low loss and low noise by a method wherein a yoke steel plate located between clamping and coupling member penetrating holes of each main leg is removed. CONSTITUTION:In the three-phase gapped type reactor whereon an interface center yoke 1 is removed and the spacer 9 of a non-magnetic material or an insulator is provided instead of the yoke 1, all the magnetic flux branched off at a wound core 8 runs in a yoke 2 along a steel plate, and the distribution of magnetic flux becomes uniform. Besides, as oil flows between the spacers 9, the yoke 2 is cooled excellently. As a result, iron loss is reduced, and temperature gradient becomes smaller, thereby enabling to suppress the increase in noise due to the enhancement of magnetic distortion. Moreover, the width of the steel plate of the yoke or the width of lamination of the steel plate is to be increased in order to make up for the reduction in cross-sectional area of the yoke generated by the removal of the interface center yoke 1.

Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To provide information about the motion at high speed of the structure of a sample by detecting changes in charged particles on an imaging surface at one or plural sites, and processing their signals. SOLUTION: A charged-particle beam from a charged particle source 1 illuminates a sample 3 via an illuminating lens system 2, and an image formed by the charged particles emitted while being transmitted or scattered is focused via magnifying imaging system lenses 4, 4' onto a fluorescent screen 5, where it is converted into an optical image. Two small-size openings 6, 6' are formed in the fluorescent screen 5, and charged particle detectors 7, 7' each constructed of an avalanche photodiode are installed behind the openings. If a specific structure of the sample 3 is put into motion, its image causes a time difference when passing through the two openings 6. 6'.  Based on the correlation on a time base between signals which the charged particle detectors 7, 7' output, a correlator 9 calculates a time difference between the signals, and calculates the moving speed of the specific structure of the sample 3 from the time difference and the distance between the openings 6, 6'.

Title: Semiconductor integrated device
Inventor: FURUYA YASUSHIGE
IPC: H01L21/3205
Filed: 1988-08-31
Abstract: PURPOSE:To inhibit the switching noise of a digital signal from spreading to an analog circuit sensitive to noise by a method wherein a shielding signal parallel with a certain signal is arranged in one of the layers under the layer of said certain signal wiring and a constant voltage is applied to the shielding signal. CONSTITUTION:When a digital signal 1 is in an operating state, switching noise is generated, but by applying a constant quiescent potential to a shielding signal 2, an electric line of force which is generated from the signal 1 is bent. The bonding force of the signal 1 with a signal 4 is weakened and a noise resistance is improved. Thereby, the wider the width of the signal 2 is made than the widths of the signals 1 and 4, the more a shielding effect is improved. As a shielding power supply 3, a power voltage and an earth voltage are generally used, but if a shielding power supply is a stable power supply which hardly fluctuates, the power supply may be an intermediate power supply between the above voltages.

Abstract: PURPOSE:To stably produce an impeller whose casting quality is satisfactory by pressurizing a molten metal once in a molten metal supply passage and injecting its molten metal to a cavity through an annular gate by an injection plunger which advances at a high speed. CONSTITUTION:When a seal pin 36 advances, its diameter expanding head part 37 is engaged to an annular stepped part 38 of a molten metal supply passage 33 and a gate 15 is closed. Subsequently, a molten metal is injected to the molten metal supply passage 33, an injection plunger 34 is advanced at low speed, and the molten metal is pressurized between the plunger 34 and the diameter expanding head part 37 of the seal pin 36. Next, immediately before the plunger 34 is shifted to high speed advance, the gate 15 is opened by moving backward the seal pin 36. In such a manner, the pressurized molten metal is injected to a cavity C through the gate 15 by the plunger 34 which advances at high speed. Therefore, the molten metal is injected roughly equally into the cavity C, and also, pressurizing force by the plunger 34 is propagated to the whole molten metal in the cavity C. Accordingly, no cold shut is generated in each blade 3, and also, an impeller in which no omitted part is generated and whose manufacturing quality is satisfactory is obtained.
