Title: Thin-film magnetic head
Inventor: HATSUTA HIROAKI
IPC: G11B5/187
Filed: 1979-07-30
Abstract: PURPOSE:To prevent the crosstalk and increase the high-density recording performance, by providing the magnetic thin film near the both sides of the magnetic gap of the thin-film head made of the magnetic metal film. CONSTITUTION:Permalloy film 2 is ion-plated onto ceramic substrate 1 to obtain lower magnetic layer 2. Simultaneously with formation of layer 2, magnetic shielding permalloy film 9 is formed at both sides of the permalloy film at the area where magnetic gap 6 is formed with minute space 8 (2-3mu) secured. The mask covers over film 9, and SiO2 film 5 for magnetic gap is formed on winding 3. Then permalloy film 10 is laminated on film 9 simultaneously with formation of the permalloy film of upper magnetic layer 4. Substrate 1 is then diced to cut out thin-film core 11 individually. Cover glass 12 is melt-stuck to core 11 for reinforcement, and then the core is stuck to slider 13 by glass 14. Then gap surface 15 is finished by lapping to form gap depth 16. Thus a magnetic head is completed. As a result, magnetic flux 20 is absorbed into film 9 from adjacent track 19 in case track information 18 is read out, thus preventing the crosstalk.

Abstract: PURPOSE:To reduce the concn. of NH4<+> ion and NO3<-> ion remarkably thermally decomposing waste water contg. NH4NO3 by the wet process in the presence of catalyst contg. a noble metal, etc., as active components at a specified pH, and specified temp. CONSTITUTION:Waste water contg. NH4NO3 is thermally decomposed by the wet process in the presence of a catalyst contg. at least one among noble metal, noble metal ion, and soluble noble metal compd. as active components, at ca. -11.5pH and 100-370 deg.C. As the result, waste water contg. NH4NO3 at high concn. is treated effectively, and the concn. of NH4<+> ion and NO3<-> ion are reduced remarkably. Accordingly, treatment of waste water having frequently above 10% NH4NO3, which, for example, discharged from a treating stage of raw material of uranium, or retreating stage of used uranium fuel, can be easily performed with a simple apparatus.

Abstract: PURPOSE:To reduce a noise level, by connecting silent ducts, different in length each, to an inside air intake of an inside and outside air selector box, making the other end approximate to their opening parts, and constituting radiant pulsation waves so as to interfere with each other. CONSTITUTION:One end of each of silent ducts 11 and 12, different in length of each ventilating passage is connected to an inside air intake 2 of an inside and outside air selector box 1. Then, opening parts 15 and 16 of the other end are set up after being approximated, whereby radiant pulsation waves are made so as to interfere with each other. In this constitution, the silent duct 11 is formed into being straight while the silent duct 12 into an L-shaped form, respectively, and each of lengths La and Lb is set so as to satisfy an expression 1 on wavelength lambda and pulsation frequency (f). With this constitution, pulsation waves produced by a blower 17 passes through these silent ducts 11 and 12 from the inside air intake 2. At this time, there is produced a phase difference due to a difference in length between these ducts 11 and 12, whereby destructive interference occurs at both these opening parts 15 and 16, and a sound pressure level is reduced. Thus, a noise is reducible owing to this constitution.

Title: Manufacture of semiconductor device
Inventor: SADAMORI MASAAKI
IPC: H01L21/329
Filed: 1980-07-16
Abstract: PURPOSE:To make a planar element high in reverse dielectric strength without any damage to the forward characteristic, by method wherein a junction forming process is performed, after diffusion of the impurities from a window of the fixed size, while the window region is widened in the circumferential direction with the diffusion of the impurities with lowered concentration added thereto. CONSTITUTION:For instance, in the process of selective diffusion of a planar type diode, a window 4 having a given size is opened in an oxide film 3 provided on an N<-> substrate 1 to form a P<+> diffusion layer 5. Subsequently, the window 4 is widened up to 4a to diffuse the impurities with the lower concentration than the time of forming the diffusion layer 5 shallower than the region 5a to form the P<+> region 5a. Further the window 4a is widened up to 4b to diffuse the P<+> region 5b with the lower concentration of the region 5a. The toral hours of these diffusions are made to be those hours wherein the diffusion layer 5 is formed to the required depth. Thereby, the effective radius of curvature of junction to be formed can be reduced, and also a depletion layer can be easily extended also to the P<+> region 5b near the surface thus to heighten the reverse dielectric strength without increasing power loss in the forward direction.

Title: Method for controlling height of weld bead in rotating arc welding method
Inventor: SUGITANI YUJI
IPC: B23K9/095
Filed: 1986-04-30
Abstract: PURPOSE:To control the height of a weld bead with high accuracy even if a groove width changes by detecting the voltage waveform of a rotating arc, detecting the groove width from the fluctuation of the voltage values in the right and left positions and changing a welding speed. CONSTITUTION:The voltage waveform of the rotating arc generated by the rotation of a rotating nozzle is detected and is divided as shown in the figure. The arc voltage values in the rotating positions Cr, L, Cf, R of the nozzle are obtd. if the respective peak voltage values are detected by a peak holding circuit. The fluctuation width of the groove 2 is detected from the fluctuation of the arc voltages EL, ER of the right and left positions. The nozzle moving speed is changed to meet such fluctuation width so that the arc voltages Ecr, Ecf are kept at the voltage values before the fluctuation. The welding is, therefore, dealt with the fluctuation of the groove width even if such fluctuation arises. The height of the weld bead is thus controlled constant with the high accuracy.

Title: Optical displacement detecting apparatus
Inventor: FUKUDA TAKUMI
IPC: G01D5/38
Filed: 1991-04-03
Abstract: PURPOSE:To lower the manufacturing cost of a laser encoder and to improve the detecting accuracy of displacement by improving a diffraction grating for forming an enlarged interference pattern. CONSTITUTION:A laser encoder is provided with a point light source 1 which emits a coherent light, and a shifting member 2 which shifts to traverse the coherent light. A phase grating 3 is formed in the shifting member 2 so as to generate an enlarged interference pattern 4 which diffracts the coherent light and moves in the shifting direction. The enlarged interference pattern 4 is detected by a detector 6 through a mask member 5, when an electric signal 7 indicating the shift of the shifting member 2 is output. The phase grating 3 can be obtained easily by stamping or molding the shifting member 2 formed of an optical material. The obtained interference pattern 4 includes interference fringes of high density, so that the resolving power is improved. Even when various kinds of parameters of the laser encoder are changed, the interference pattern 4 has a constant visibility at all times. Since the phase grating 3 forms the interference pattern 4 by adding the phase difference to the coherent incident light, the diffraction loss is small, and tone contrast is improved.

Filed: 1989-04-20
Abstract: PURPOSE:To provide a stabilized DC power source upon occurrence of overcurrent at the load side due to power interruption by obtaining control power source from the output of an inverter circuit upon interruption of AC input. CONSTITUTION:Upon interruption of AC input, power having voltage level to be determined by the peak output voltage of an inverter 103 is fed to a control power source circuit. Since the peak output voltage of generally employed PWM control inverter equals to DC input voltage of the inverter, power having potential to be determined by the voltage of a battery 106 is fed upon interruption of AC input. Since the voltage to be fed to the control power source is maintained at a level determined by DC input voltage of the inverter circuit 103 even upon occurrence of overcurrent at the load 105 side, DC power having stabilized voltage level can be fed to the control power source circuit.
