Title: Magnetic head
Inventor: SATOMI MITSUO
IPC: G11B5/187
Filed: 1988-10-28
Abstract: PURPOSE:To obviate the adhesion of magnetic material components in a tape under low humidity environment and to obtain stable output by using a material essentially consisting of MnO-MO2 as an interlayer insulating material or gap spacer material of a multilayered structure. CONSTITUTION:An amorphous alloy film and the interlayer insulating material are alternately sputtered to obtain the multilayered blocks of the amorphous alloy films. A substrate 5 consisting of the same material as the material of a substrate 1 is adhered thereto via a glass layer 4 for adhesion, by which the laminated core is obtd. A winding window 6 is worked to the gap butt surface and thereafter the butt surface is worked to a specular surface by diamond paste. The gap spacer material is then sputtered on this surface to a prescribed thickness to complete one side for gap formation. The prescribed head is cut out of a pair of such bars to complete the head. The interlayer insulating or gap material consists essentially of the MnO-MO2 in this case. The adhesion of the magnetic material components in the tape to the head is obviated even during tape traveling in the broad environment practically used and the stable output is obtd.

Title: Frequency synthesizer
Inventor: NAKANE MASABUMI
IPC: G01S13/32
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To suppress the spurious and to secure a wide band by synthesizing the frequency of a DDS(direct digital synthesizer) and a direct synthesizing type synthesizer. SOLUTION: The high frequency is required for the output signal of a DDS 2 in order to obtain a filter which eliminates the undesired nearby waves of a desired wave that was synthesized with the output signal of a direct synthesizing type synthesizer 7. Thus, the frequency of output signal of the DDS 2 is converted into the high frequency by a frequency up converter via the mixers of plural stages. A chirp function generation part 9 generates the updating timing of frequency, decides the output frequency in response to the chirp band width and the step frequency and generates a chirp data frequency to designate the address of a memory 10. The memory 10 outputs both frequency rough and fine setting data to control the synthesizer 7 and the DDS 2 respectively. Thus, the output frequency is roughly set by a specific channel space and finely set by the step frequency of high resolution.

IPC: G01N1/28
Filed: 1989-10-25
Abstract: PURPOSE:To decide the generation of expansion deterioration by an alkaline aggregate reaction and the alkaline aggregate reactivity of the aggregate by measuring the electric resistance in cured mortar after curing the mortar for a specified period of time. CONSTITUTION:The molding formed by kneading and molding the same aggregate with two kinds of cement having a low alkali ratio and high alkali ratio is cured at 40 to 70 deg.C curing temp. higher than the ordinary curing temp. (20 deg.C) by accelerating the reaction rate in a manner as not to affect the structure and compsn. of the cured body. The difference in the electric resistance between two kinds of the cured mortar is measured. The electric resistance in the cured mortar increases when a certain chemical reaction arises on the surface of the aggregate. The formation of an alkali silica gel arises between the aggregate and the paste and a change in the electric resistance arises therebetween when the alkaline aggregate reaction takes place in the concrete. Namely, the alkaline aggregate reactive aggregate which reacts slowly is decided early and easily with a small amt. of the sample and with good reproducibility.
