Title: Magneto-resistive head
Inventor: KAWAI TETSUO
IPC: H01F10/32
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To enable a large output by performing the magnetic domain control of the free layer of a spin valve element with the antiferromagnetic layer joined on the whole surface of the surface of one side of the free layer to enable a magnetic domain control magnetic field enough to prevent the making of the magnetic domain of the free layer multiple to be impressed even when the track of a head is narrowed and the gap length of the head is narrowed. SOLUTION: The antiferromagnetic layer 1 arranged under a free layer 2 does not affect magnetizations of fixed layer 4 and the magnetizations of the fixed layer 4 are fixed in the direction of the film with the antiferromagnetic layer 5 laminated on the fixed layer 4 and angles) formed by respective magnetizations of the fixed layer 4 and the free layer 2 become 90 degrees and an output which utilizes a huge magneto-resistance effect at maximum is obtained. Moreover, since the magnetic domain control magnetic field from the antiferromagnetic layer 5 becomes a constant value throughout the free layer 2 and this value is not affected by the gap length, even when the magnetic domain control magnetic field enough to prevent the making of the magnetic domain multiple is impressed throughout the free layer 2, the generation of a low sensitive area is not present. Thus, the generation of the low sensitive area nearby the antiferromagnetic layer 5 performing the magnetic domain control is suppressed and even when the track width of the head is narrowed, the abrupt reduction of the output is not generated.

Title: Solid-state electrolytic capacitor with fuse
Inventor: NISHIYAMA TOSHIHIKO
IPC: C01B32/60
Filed: 1992-01-20
Abstract: PURPOSE:To reduce the quantity of heat generated upon accidental short circuit of a solid-state electrolytic capacitor element by coating the whole or a part of the capacitor element with a second insulator containing a compound which performs endothermic reaction at the time of thermal decomposition reaction. CONSTITUTION:An external negative terminal 4 is provided on an insulator 5 which covers a part of a negative layer, and the external negative terminal 4 is electrically connected to an exposed part 1a of the negative layer through a fuse 6 traversing the insulator 5. Besides, the exposed part 1a of the negative layer is coated with a second insulating layer 7 containing a mixture of manganese carbonate, magnesium carbonate, and lead carbonate. If this capacitor element 1 is short-circuited and generates heat, a compound constituting the second insulating layer 7 is thermally decomposed, and performs endothermic reaction and lowers the ambient temperature. Consequently, it becomes possible to remarkably reduce failures of burning caused by the bridging between the negative layer 1a and the external negative terminal 4 through melted solder.

Abstract: PURPOSE: To achieve recrystallization of a deep drawing shaped article as well as excellent dimensional accuracy with high reproducibility by heating the shaped article to a crystallizing temperature in a heated mold for a certain time before introducing and cooling a high dimensionally accurate cooled male mold. CONSTITUTION: A shell 2 is formed from a flat polyethylene terephthalate sheet 1 by a deep drawing die 4 or any other thermoforming. The shell 2 is then moved to a heated female mold 5 for recrystallization. Heating is performed by an electrical resistance heater 6 for adjusting it to a predetermined temperature by a temperature sensor 7 and a control switch 8. After a crystallizing time which is adjusted according to the material and the shaped article passes, a cover plate 10 is removed. A high dimensionally accurate male mold 12 is instead introduced into the shell. The cooled male mold 12 is sunk for recrystallization so that the heat leaves the shell 2 due to the heat conduction. In a cooling process after recrystallization, the shell 2 obtains high dimensionally accurate internal and external shapes precisely adapted to the dimension of the cooled male mold 12.

Filed: 1981-01-21
Abstract: PURPOSE:To obtain a picture in which the noise is eleminated by curtting picture elements, which have density levels lower than the average level of the  input picture, in the preprocessing. CONSTITUTION:A preprocessing circuit 10 for an input picture generates a picture (d) where picture elements having density levels lower than the average level of the input picture are eliminated. A frame picture generating circuit 20 quantizes the preprocessed picture by a high threshold to obtain a frame picture. A mergenece processing circuit 30 discriminates the level of a noticed picture element of a frame picture e' to obtain a merged picture f'. A quentizing circuit 40 generates a binary quantized picture g', and the picture g' is sent to a mask processing circuit 50 and is subjeted to the mask processing by the picture f'. Consequently, since most of noise is eliminated in the preprocessing, a picture is obtained where required picture information such as outline parts of characters is preserved almost completely.

Abstract: PURPOSE:To extract only a desired signal without causing the reflection of a disturbing signal to a signal source and the radiation of the disturbing signal into space by decomposing a desired signal and the disturbing signal by means of a directional filter and using a resistor so as to terminate the disturbing signal. CONSTITUTION:Since the line length of a resonator 12 is made equal to the wavelength of the disturbing signal, when a desired signal including the disturbing signal is inputted to an input terminal 13a of an input line 13, the disturbing signal is outputted to a signal output terminal 14a of an output line 14. Since the desired signal is outputted at an output terminal 13b of the input line 13, the reflection of the disturbing signal to the signal source of the desired signal is not caused. Moreover, since the signal output terminal 14a of the output line 14 is terminated by a termination resistor 15 of the nearly same value as the characteristic impedance of the output line 14, the radiation of the disturbing signal into space is not caused.

Abstract: PURPOSE:To obtain an output waveform in which both leading edge and trailing edge are steep even for the load of a large capacity by constituting a GaAs logic circuit of a complementary logical gate part and a buffer circuit, achieving a low power consumption and constituting a buffer circuit of an (n) channel type FET only. CONSTITUTION:A title circuit is composed of a complenetary logical gate part 11 and a buffer circuit 12. The output of the logical gate part 11 is made into a node P and the potential is made into Vp. At this time, when an input terminal IN is a low L level, the Vp becomes the H level, nFET 15 of the buffer circuit 12 is turned on, nFET 16 becomes the OFF condition and an output terminal OUT becomes the H level. When the input terminal IN is an H level, the L level is obtained, and the nFET 15 is turned off, other nFET 16 becomes on and the output terminal OUT becomes the L level. Namely, in the buffer circuit 12, when one side nFET becomes on, other nFET becomes off, and therefore, the stationary current to flow from a supply voltage terminal Vcc to a ground GND is made very small.
