Title: Magnetic sensor device, its manufacture, and manufacture of magnetic material used therefor
Inventor: MATSUDA TOSHIO
IPC: H01L43/04
Filed: 1994-01-28
Abstract: PURPOSE:To improve the sensitivity of a magnetic sensor device and reduce the variation of the sensitivity by providing a magnetic material on a magnetism sensitive part in an isolating state and making the lower part of the magnetic material facing the magnetism sensitive part thinner than the upper part. CONSTITUTION:A partial defect is provided by selectively removing part of a polyimide organic insulating film 14 on an InSb layer 11 which is the sensitive part of a magnetic sensor by using an organic solvent. Then a semispherical ferrite body 15 is die-bonded to the layer 11 as a magnetic material with insulating paste 16 so that the spherical part on the bottom of the body 15 can be put in the partial defect where the film 14 is removed. Thus the ferrite body 15 put on the magnetism sensitive part as a magnetic material is made smaller in size as it goes toward the bottom. As a result, the sensitivity of the magnetic sensor can be improved, because the effective magnetic flux density at the magnetic sensor part is increased by leaps and bounds.

Title: Binary-to-decimal conversion system
Inventor: SAWAMOTO TAKESHI
IPC: H03M7/12
Filed: 1981-01-23
Abstract: PURPOSE:To increase a binary-to-decimal conversion speed by discriminating one of decimal numbers 0-9 which corresponds to a binary input number. CONSTITUTION:Comparing means 11-19 read a numeral and digit data out of a storage device stored previously with numerals 1-9 and decimal number data, and compare a refernce value nearly in the middle of the lower limit and upper limit values of each digit with the binary input number. Thus, the comparing means 11-19 discriminate the binary input number on the basis of its value successively to discriminate one of decimal numbers 0-9 which corresponds to the input number. Consequently, a necessary frequency of discrimination is decreased.

Filed: 1993-01-22
Abstract: PURPOSE:To make possible F-class operation and raise efficiency by connecting a resonance circuit, where the secondary harmonics of the frequency of microwave band is set to resonance frequency, between split drain electrodes and earth. CONSTITUTION:The metallic wiring of a drain electrode is cut to divide the drain electrode 1 of an FET, where the width of the gate is increased for high output, into at least two pieces or more. And, the adjacent metallic wirings are connected with each other by the resistor 2 being made of a semiconductor resistor layer doped in high concentration with impurities. And, a resonance circuit for processing secondary harmonics to short circuit is made from the divided drain electrodes directly onto a GaAs substrate. The resonance circuit is constituted of a transmission 3 and an MIM structure of capacitor 4. The circuit constituted this way prevents impedance from becoming small by dividing the drain side, so a harmonic processing circuit can be added directly to the FET short in gate width through a resistor.

Title: Rolling method for steel sheet
Inventor: HIRASAWA TAKESHI
IPC: B21B1/38
Filed: 1979-01-31
Abstract: PURPOSE:To reduce the roll bending factor, and to manufacture the steel sheet of breadth of wide range and of small sheet crown, without interchanging the rolls, by forming the taper zone with length of specified % of the drum length and with a specified taper angle, at both ends of backup rolls of the four-stage rolling mill. CONSTITUTION:At both ends of backup rolls 1, 5, the taper zones are formed with the chamfer length (a) being 5-32% of drum length L, and the angle theta being 0.01-1 deg.. This taper zone can be formed into one-stage or more, and also can be asymmetry between upper and lower backup rolls. These tapered rollers are built in as the backup rolls against the work rolls 2, 4, which then can carry out the rolling work for the sheet 3. With the increase of the rolling load, the contact breadth between rolls 1, 5, and 2, 4, becomes longer, hence, the roll bending factor K can be reduced against the sheet of breadth of wide range. Besides, by impressing the bending force on the rolls 1, 5, and/or 2, 4, above stated contact condition is changed correspondingly to the breadth of the rolled sheet, and the value of the factor K is further reduced.

Title: Method and device for preventing information leak of secondary storage device
Inventor: KOBAYASHI TAKASHI
IPC: G06F21/88
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To prevent information leak when a secondary storage device is stolen, etc., by copying a part of contents of the secondary storage device to nonvolatile memory when power source is off and writing invalid data to a part of the contents of the secondary storage device. SOLUTION: In a leading area 1-2 of a hard disk drive 1-1 file management information is stored. When the power source is off, interruption of power source off from a power supply device 1-9 occurs and it is notified to a CPU 1-7. The interruption makes the software of a BIOSROM 1-8 operate and copies data in an area 1-2 to an SRAM 1-10. Next, the software of the BIOSRAM 1-8 writes invalid data in the area 1-2 and makes the device 1-9 execute an actual power source off operation after it is finished. When the drive 1-1 is stolen and is connected to another personal computer, it is actually impossible to start an OS and to read file contents because management information 1-2 is destroyed.

The voltage of the resistor 5 is compared with the reference voltage through the comparator 10, and at the same time the integral voltage of the integrating capacitor 7 is compared with the reference voltage through the comparator 12. The comparator 10 produces the output signal when the pulse duration is <=1/2 cycle for the driving signal which is applied to the semiconductor switching element; and the comparator 12 produces the output signal when the pulse duration is >=1/2 cycle, respectively. This output signal is applied to the overcurrent protecting circuit to secure an overcurrent operation.

In addition, electrolyte prepared by dissolving zinc oxide into 35wt% aqueous potassium-hydroxide solution, is poured into such a battery. As a result, the charge-and-discharge reversibility of the battery can be enhanced by decreasing the sizes of silver grains produced due to electric discharge.
