Title: Magnetic recording medium
Inventor: ICHIKAWA YOSHIAKI
IPC: C09D7/12
Filed: 1987-01-30
Abstract: PURPOSE:To improve a magnetic flux density by providing a 1st magnetic coated film essentially consisting of a magnetic material having an axis of easy magnetization within the plane on a nonmagnetic base and providing a 2nd magnetic coated film essentially consisting of a magnetic material having an axis of easy magnetization perpendicular to the film plane thereon. CONSTITUTION:The coated film 1 essentially consisting of the magnetic material having the axis of easy magnetization within the plane is provided as the 1st magnetic layer on the nonmagnetic base 2 of a magnetic recording medium for a magnetic revolution sensor. The coated film 3 essentially consisting of the magnetic material having the axis of easy magnetization perpendicular to the film plane is further provided as the 2nd magnetic layer thereon. Formation of the films into 3-layered structure by providing a nonmagnetic coated film 7 between the coated film 1 and the coated film 3 is equally satisfactory. A 3rd magnetic layer which is subjected to a magnetic field orientation treatment by a floating magnetic field from the coated film 3 and is thereby oriented toward the direction of the magnetic flux of an underlaying film more strongly than in the coated film 3 may be further provided on the coated film 3 at the time of magnetizing the coated film 3 to some magnitude in the forming stage of the coated films 1, 3 and providing the 3rd magnetic coated film thereon. The magnetic flux density is increased to about two-fold the magnetic flux density of the conventional medium by such constitution, by which the assembly of the magnetic sensor is facilitated and the reliability at the time of the assembly is enhanced.

Title: Constant speed control circuit for dc motor suppressed for production of noise, vibration
Inventor: BAN ITSUKI
IPC: H02P7/29
Filed: 1981-02-16
Abstract: PURPOSE:To suppress the production of noise and vibration of a DC motor by setting the energizing current waveform of the motor to a voltage waveform half-wave or full-wave rectified from the AC voltage of a semiconductor switching element and a freewheel diode. CONSTITUTION:When an armature current detection output detected by a resistor 10 is raised over the upper side slice level of a Schmitt trigger 26, transistors 27, 7 are interrupted, the magnetic energy of a motor 9 is discharged  through a freewheel diode 11, thereby gradually reducing the armature current.  As th armature current decreases, the detected output of the resistor 10 is lowered over the lowerside slice level of the Schmitt trigger 26. Then, the transistors 27, 7 are conducted, and the armature current is again increased. Accordingly, the constant speed control determined by the hysteresis width of the Schmitt  trigger 26 is performed by controlling the gate voltage of the FET14 and the  output of the OP amplifier 17 by the output of an error amplifer 30.

Title: Mig arc welding method
Inventor: AKUSA KAZUO
IPC: B23K9/16
Filed: 1979-02-23
Abstract: PURPOSE: To enable the DC positive (negative) captioned welding to be done in inert gas not added with any active component by transferring the droplets formed by arc heat at the end of the welding wire containing the specific amount of rare earth elements as welding arc characteristic improving components to the base metal side through contact-shortcircuiting with molten pool metal surface.  
     CONSTITUTION: As welding arc characteristic improving components, rare earth elements are added 0.02W0.3% into welding wire. Thence, the droplets formed by arc heat at this wire end are transferred to the base metal side by being instantaneously contact-shortcircuited with the molten pool metal surface in an inert gas atmosphere such as pure Ar. According to this method, the welding wire end is sharpened in the arc and the stable reiteration of the instantaneous contact-shortcircuiting with the molten pool metal surface at this sharpened end is continuously accomplished. Further, there is no need fod adding active gas such as O 2  or CO 2  to the inert gas and the reduction of the O 2  amount in the molten metal and the improvement of toughness become feasible.

IPC: G03G15/00
Filed: 1986-01-31
Abstract: PURPOSE:To get rid of the stoppage period for receiving by controlling the device so that kth(k=1, 2...N) distribution may be executed according to the specified formula when the contents successively accepted to the bin number as 1, 2...n in order from the top distribute the same N(NSn) pieces of sheet. CONSTITUTION:Numbers 1, 2...n are attached, in order from the top, to plural bins in advance. And the kth(k=1,2...N) distribution of N(N<=n) pieces of sheet having the same contents accepted in order is executed according to a formula I or a formula II. For example, when N=9, the sheet is discharged to 1 bin on the highest step, next 3 bin, 5 bin, 7 bin, 9 bin, on one stroke of arrangement. Next the sheet is discharged, while being elevated successively, to 8 bin above the 9 bin and further to 6 bin, 4 bin, 2 bin and after finishing one stroke it shifts from 2 bin to 1 bin and shifts to the next stroke. Hereby the time needed in changing the stroke is shortened and the stoppage period for acceptance is made needless and it becomes needless to controll the sheet discharge of a main body by sorter.

Filed: 1988-01-29
Abstract: PURPOSE:To simplify a program at the side of a host computer by absorbing the difference of display areas and displaying the graph display data of a single type. CONSTITUTION:The information (a) showing the area of a virtual display area is received by a 1st reception means 1 from a host computer CPU 10. An analyzing means 2 analyzes the mapping to the area of a real display area from the area of the virtual display area. At the same time, a 2nd reception means 3 receives the graph display data (b) produced based on the area of the virtual display area received from the CPU 10. A conversion means 4 converts the data (b) into a graph display data train (c) corresponding to the area of the real display area based on the result of analysis obtained by the means 2. Then the result of said conversion is stored in a memory 23 contained in a display device via a display means 5.

Filed: 1981-02-17
Abstract: PURPOSE:To enable a higher dot density without changing the size of a character by performing interpolation on the entire character in two or more out of eight directions centered on one dot in an original character pattern. CONSTITUTION:When a pattern generated from an original character pattern generator 2 is increased in the dot density, it is transmitted to a dot density expanding device 4. An interpolation of the entire character is made in two or more out of eight directions in total centered on one dot in an original character pattern read from the original character pattern generator and then, transmitted to an expanded pattern memory 5. When the number of printing elements of a print head is shoft of the number of matrixes to be printed, after a pattern division with a printing pattern divider 6, a printing section 8 performs a printing according to the pattern stored in a scanning pattern memory 7. This method does not require the memory of enlarged patterns to have capacity enough to cover all characters corresponding to any original character pattern thereby enabling the economization of a scanning memory.

Title: Supercharger controller for engine combined with automatic transmission with lockup mechanism
Inventor: MATSUOKA TOSHIHIRO
IPC: F02D29/00
Filed: 1989-01-31
Abstract: PURPOSE:To improve accelerability in a lockup state by compensating a lockup clutch of a torque converter in direction of raising the extent of supercharging pressure as compared with at time of a nonclamping state when it is in a clamping state. CONSTITUTION:A supercharging pressure regulating means regulates the extent of supercharging pressure being generated by a supercharger. When a lockup detecting means detects that a lockup clutch of a torque converter is in a clamping state, a supercharging pressure compensating means compensates it in direction of raising the supercharging pressure as compared with at time of its nonclamping state, and the supercharging regulating means controls the supercharging pressure according to this compensated desired value. Supposing that a lockup range is expanded for fuel consumption improvement like this, engine power is increased together with the lockup, so that a shortage of acceleration at time of lockup operation can be thus compensated.
