Title: Insulated gate type bipolar transistor
Inventor: YAMAMOTO TAKESHI
IPC: H01L29/06
Filed: 1990-04-30
Abstract: PURPOSE:To eliminate a latchup by controlling a first carrier electric resistance value by a source layer shape between a first contact and a channel region, and preventing conduction of a pn junction. CONSTITUTION:A p<+> type silicon substrate is prepared, and an n<-> type layer of low impurity concentration semiconductor is formed by an epitaxial growth. A p<+> type drain layer 1, an n<-> type drain layer 2 are formed of the substrate and the n<-> type layer, and the surface of the layer 2 is oxidized to form a gate oxide film 3. A gate electrode 4 of a polysilicon film is formed thereon. With the electrode 4 as a mask boron is diffused to form a p-type base layer 5. Then, the center of the window of the electrode 4 is covered with a resist film patterned in a shape opened in a T shape, phosphorus ions are implanted to form an n<+> type source layer 6. Since carrier electric resistance value R1 is controlled by the shape of the layer 6 to prevent conduction of the pn junction, a source resistance is improved to prevent a latchup.

Title: Method for protecting refractories against slag coexisting with molten metal
Inventor: KIMURA MORIHIRO
IPC: B22D41/00
Filed: 1980-08-25
Abstract: PURPOSE: To isolate a slag layer from refractories and protect the refractories by applying a moving magnetic field in a perpendicular direction to the slag in the upper part of molten metal from the outside of the refractories.  
     CONSTITUTION: In case when molten metal 2 flows in a runner formed of horizontal refractories 1, an electromagnetic coil 3 is provided on the outer side of the wall surface of the refractories 1 in such a way that electromagnetic force acts in the direction at a right angle to the flow of the molten metal 2, that is, perpendicularly in the figure. If the electromagnetic force of arrows 3a is acted upon the coil 3, the molten metal near the refractories 1 is lifted along the wall surface of the refractories like arrows 3b. At this time, the slag layer 4 itself existing in the upper layer of the molten metal 2 does not receive any electromagnetic force and therefore it slips down as much as the molten metal 2 is lifted, so that only the molten metal 2 contacts the refractories 1, whereby the intensive reaction with the slag 4 is prevented.

Title: Injection molding machine
Inventor: NEKO TETSUAKI
IPC: H02P23/18
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To provide an injection molding machine capable of speeding up the molding cycle. SOLUTION: The current control for an AC servo motor 4 for driving a movable section of an injection molding machine is performed by utilizing the d-q conversion. For the purpose of compensating the reduction of torque of magnetic saturation, the phase correction amount θm (b) is added to the motor phase θr (5). The d-q conversion is performed by the actual current of three phases of the servo motor 4 and the corrected rotor phase θ (=θr+θm), and the (d) phase current Id in the magnetic flux direction formed by the field magnet and the (q) phase current Iq crossing orthogonally the (d) phase current Id are found (7). The (q) phase command is used for the toggle command, and respective current loop controls are carried out by using the (d) phase current command as [0] (Id, Iq), and the command voltages Vd and Vq are found.  The voltage commands are converted to three phase voltage commands Vu, Vv and Vw by a 2 phase - 3 phase convertor 2, and the servo motor 4 is driven through a power amplifier 3. The phase delay of the current loop is not generated to reduce the ineffective current and generate high torque. The motor heat development is small, and the molding cycle can be shortened.

Filed: 1982-07-06
Abstract: PURPOSE:To enable easily the setting of an alarm time without the misoperation by the operator, by introducing the time right after the end of the operation for setting the alarm time. CONSTITUTION:A key board 10 has numeric inputting keys 11, an input end key 12, an input key 13, a set key 14 for an alarm time, etc. A display device 20 displays alphanumeric characters. A CPU 30 has the functions of receiving the signal from the keyboard 10, executing the various calculations corresponding to respective keys, displaying the same on the device 20, storing data in a clocking circuit 50 and reading out the data and the function for sounding a buzzer 40. The circuit 50 which performs normally clocking operation transfers the data therein to the CPU 30 when the CPU 30 reads out the present time. When the key 12 is depressed upon ending of all the inputting operations, the present time data is introduded from the circuit 50 to the CPU 30. The misoperation when the data or time changes during inputting of the alarm time data is thus prevented.

Abstract: PROBLEM TO BE SOLVED: To improve the through rate without greatly increasing the power consumption or causing deterioration in small signal characteristics by supplying a specific current to an output terminal when the difference voltage between the uninverted and inverted input terminals exceeds a threshold. SOLUTION: When the difference voltage between nodes 1N1 and 1N2 exceeds a certain threshold, a bias current begins to flow from a transistor(TR) Q13 as a constant-current source to a TR Q12, whose drain current is amplified by a current mirror circuit 14 at A times as high as mirror ratio and outputted to a node 'OUT'. Namely, the current which is A times as large as the drain current of the Q12 is outputted to the node 'OUT' as the drain current of a TR Q15 and an external circuit connected to the node 'OUT' is supplied with the sum of the output current from an operational amplification part 15 and the output current from the current mirror circuit 14 to speedily charge a load capacitor CL. Consequently, the voltage at the node 'OUT' rises rapidly to improve the through rate, thereby driving the large load with low power consumption.
