Title: Magnetic head
Inventor: IDE NORIYUKI
IPC: G11B5/133
Filed: 1985-07-12
Abstract: PURPOSE:To obtain an inexpensive magnetic head by constituting a winding part of single crystal ferrite and constituting part of bodies in common use as a slider of a material except the single crystal ferrite. CONSTITUTION:The single crystal ferrite is used only for the winding part 4 and the polycrystalline ferrite is used for bodies 6 in common use as the slider facing said part via gaps 5, 5'. The use of the single crystal ferrite is limited only to the winding part particularly important for a magnetic circuit. The single crystal ferrite is otherwise used for the part 9 constituting the magnetic circuit in the winding part 7 and the bodies facing each other via gaps 8, 8 and the nonmagnetic polcyrstalline ferrite or ceramics is used for the remaining part 10. The constituting ratio of the single crystal ferrite is thereby considerably decreased without deteriorating the magnetic characteristics and the inexpensive magnetic head is made obtainable.

Title: Gate control circuit for gate turn off thyristor
Inventor: TOMINAGA KAZUO
IPC: H03K17/732
Filed: 1980-11-05
Abstract: PURPOSE:To obtain a large OFF gate current by providing a small capacity GTO thyristor in a gate circuit of the GTO thyristor. CONSTITUTION:When a transistor 2 is turned OFF, a current flows from a power source 3 to a gate cathode of the GTO thyristor 12 through a resistor 4 and a capacitor 13. The GTO thyristor 12 is turned ON. As a result a current flows through the cathode gate of the GTO thyristor 1 and the GTO thyristor is turned OFF. When the transistor 2 is turned ON, the electric charge in the capacitor 13 is discharged through the cathode gate of the GTO thyristor 12, and the GTO thyristor 12 is turned OFF. As a result, electromagnetic energy in a current transformer 8 is flowed through a transistor 11 and the gate cathode of the GTO thyristor 1, and the GTO thyristor 1 is turned ON. Since the OFF gate curent of the GTO thyristor 1 is controlled by the GTO thyristor 12, the large OFF gate current can be flowed.

Title: Constant voltage circuit
Inventor: KAMI HIRONORI
IPC: G05F3/18
Filed: 1993-06-25
Abstract: PURPOSE:To suppress power consumption so as to be approximately fixed even when an input voltage fluctuates by connecting a high resistor between the gate/source of an nMOS transistor and also connecting a constant voltage generation element. CONSTITUTION:The resistance value of the high resistor RH connected between the collector C of an npn transistor TR and the gate G of the nMOS transistor M and the voltage drop of an diode array DA which is the constant voltage generation element connected between the gate/source of the nMOS transistor are set so as to let the nMOS transistor M operate in a saturated area. Thus, at the time of operations, the voltage between the gate/source of the nMOS transistor M becomes equal to the voltage drop in the diode array DA and becomes approximately fixed. Thus, a fixed current corresponding to the voltage between the gate/source is made to flow to the nMOS transistor M. Since the current flowing to the high resistor RH and the diode array DA which is the constant voltage generation element is originally suppressed so as to be low, the fluctuation of the power consumption is small.

IPC: G06F17/50
Filed: 1988-06-24
Abstract: PURPOSE:To produce an easy-to-see tree picture in a more natural form by forming the tree parts in different forms from each other and changing the number of branches, the lengths of branches, the spaces among branches, and the presence of twigs according to the height of the tree. CONSTITUTION:The height of a tree and the tree generating position are inputted as parameters. Then the height of the tree is sent to a controller 1-3. The controller 1-3 gives an instruction to a random number generating part 1-4 to produce a random number as the number of branches. A reference table 1-5 selects the random number based on the set reference and an arithmetic unit 1-6 processes said random number as the data and calculates the branch coordinates from the processed data and the trunk coordinates from the input height and position respectively. A memory part 1-7 stores the final data and outputs this data to a graphic display 1-8 if the display is desired. Thus the necessary tree parts can be produced on a display screen in more natural and easy-to-see forms.

The substrate 7 is brightly observed by fluorescence whereas the pattern 8 or soldered part 12 having no fluorescence is darkly observed. Therefor, the contrast of brightness between the substrate 7 and the pattern 8 or soldered part 12 is extremely sharp and the position or shape of the pattern 8 or soldered part 12 can be sharply observed.
