Title: Pll output stable circuit
Inventor: ICHIKAWA TAKUYA
IPC: H03L7/08
Filed: 1994-06-03
Abstract: PURPOSE:To make the output of the PLL circuit stable by forming a current injection circuit with transistors(TRs) and using the TRs in the saturation state to keep a base current constant even when the base voltage of the TRs is changed through the change in an oscillated frequency from the PLL circuit. CONSTITUTION:A signal outputted from the charge pump circuit of a phase comparator 1 is fed to the base of a TR 20 via a resistor 21 whose resistance is comparatively high in a current injection circuit 2. A collector-emitter voltage of the TR 20 is selected to be a prescribed voltage or over at which the TR 20 is saturated. Furthermore, the base-emitter voltage of the TR 20 is selected constant. In this case, even when a base input voltage changes, the base current is constant. Even when a frequency from the VCO 4 is changed depending on the change in the output voltage of the phase comparator 1, the current supplied to the base of the TR 20 is constant and a current cancelling this current is supplied to the phase comparator 1, any of TRs of the charge pump circuit in the phase comparator 1 repeats ON state and the output is made stable.

Title: Manufacture of static induction type semiconductor device
Inventor: HORIUCHI KAZUYUKI
IPC: H01L29/74
Filed: 1988-05-19
Abstract: PURPOSE:To suppress an autodoping at the time of epitaxial growth, and to alleviate a gate dig etching accuracy by etching a part of a semiconductor layer to expose the electrode leading region of a gate layer, and forming a reverse conductivity type guard ring on the semiconductor layer around the region. CONSTITUTION:After the surface of a substrate 10 is cleaned by vapor etching, a high resistance N<-> type semiconductor layer 12 is formed by epitaxially growing. Thus, since a P<+> type impurity layer to become a guard ring is not formed on the surface of the substrate 10, an impurity for causing an autodoping in case of epitaxial growth is reduced, thereby suppressing the autodoping. Subsequently, in order to expose a connecting region 5, the layer 12 is so removed by etching in depth as to reach the region 5. A P<+> type high concentration impurity is diffused in the semiconductor substrate 10 around the removed region 5 to form a guard ring 7. Thus, the autodoping is largely suppressed when the epitaxial layer is formed, and a high resistance epitaxial layer can be formed.

Title: Step motor driving circuit for floppy disc unit
Inventor: OKAWA YOSHIHISA
IPC: H02P8/12
Filed: 1991-04-26
Abstract: PURPOSE:To widen the range of stepping speed in which a magnetic head can perform seeking operation stably with no trouble of noise. CONSTITUTION:Multivibrators 2, 4 are triggered by the rising of a step signal and produce a signal 2a having pulse width t1 and a signal 4a having pulse width t3, respectively. A multivibrator 3 is triggered by the rising of trailing edge to produce a signal 3a having pulse width t2. The signals 3a, 4a are fed to an AND gate 5 which then outputs a signal 5a. A voltage control circuit 6 provides an exciting circuit 7 with an exciting voltage which is a voltage E for Low level signal 5a and a lower voltage E' for High level signal 5a. Consequently, when the stepping speed is low and the step period is longer than the pulse width t1, a step motor 8 is excited with the lower voltage E' for an interval corresponding to the pulse width t3 at the start of stepping operation and thereby the torque lowers.

Abstract: PURPOSE:To make the distribution of dopant uniform by a method wherein a dent consists of a vertical side wall and a bottom having a gentle circular curve around a flat, central part, the circular curve starts with the vertical side wall and terminals with a flat, middle section bottom, and the horizontal and the vertical distance between the starting and terminating sections is specified. CONSTITUTION:A dent suction consists of a vertical side wall and a bottom section having a gentile circular curved around a flat middle section. The circular curve starts with the vertical side wall and terminates with the flat, central bottom. The horizontal distance (r) between the starting and terminating sections is 10-30% of that of the substrate's diameter, and the vertical distance alpha is 25-125mum, thereby making it possible to make the distribution of dopant less than + or -3% in the expression of the proportional resistance because, if the (r) deviates from the range 10-30% of the substrate's diameter, and the (d) deviates from the range 25-125mum, then the distribution of dopant will become more than + or -5% in the expression of the proportional resistance, making it impossible to obtain a wafer with uniform distribution of dopant.

Filed: 1982-07-15
Abstract: PURPOSE:To improve efficiency of charge by the quantity sent in through an auxiliary air intake passage after closing a main air intake valve by closing an auxiliary air intake valve later than the main air intake valve. CONSTITUTION:When an engine comes to an intake stroke, a main air intake valve 7 is opened in the same way as that of a conventional engine and mixed gas is inhaled from a main air intake passage 5 during a lowering stroke of a piston 4. When the piston 4 is brought to the end of the lowering stroke, an auxiliary air intake valve 8 is opened and the intake is performed from both the main and the auxiliary air intake valves. When the piston 4 turns to an elevating stroke, the main air intake valve 7 is closed at 45 deg. after the lower dead center of the crank angle, while the auxiliary air intake valve 8 is closed at 60 deg. likewise. When the main valve 7 is closed, since a large quantity of the main air intake current is stopped at one time, surging pressure is caused in an air intake passage adjacent to the main air intake valve 7. The surging pressure is a little higher than the pressure of mixed gas under compression in a cylinder 2, and the mixed gas is forced into an engine chamber 1 through the auxiliary air intake valve 8.
