The slope of the voltage to be applied to the semiconductor switching element 6 is quickly relaxed, and rise of the peak value of the voltage is restrained. When all of the charge of a primary side coil of a high-voltage transformer 4 has been transferred to the capacitor 5, current starts to flow from the capacitor 5 to the primary side of the high-voltage transformer 4. When the voltage level to be applied to the semiconductor switching element 6 is lowered, capacity is returned to the original condition due to the voltage dependence of the capacitor 5, and the voltage to be applied to the semiconductor switching element 6 is quickly lowered.

Abstract: PURPOSE:To offer an electrostatic induction semiconductor device whose irregularity of the threshold voltage is small, by a method wherein diffusion distance of impurity in the transversal direction can be exactly controlled, by forming the edge of a window of a gate region forming mask in a taper-form, and implanting impurity. CONSTITUTION:A semiconductor wafer provided with a mask 3 having a window 2 for forming a gate region is prepared. As to the mask 3, the edge 3a of the window is shaped a taper-form.

By giving a gradient like this to the impurity concentration, the reaching position of impurity can be exactly approached to a specified location. In the obtained electrostatic induction semiconductor device, therefore, the threshold voltage becomes very approximate to a specified value, and the range of irregularity can be reduced.

Title: Method and equipment for controlling start at time of cold in internal combustion engine
Inventor: KAARUUHAINTSU KUUGURAA
IPC: F02N19/00
Filed: 1994-09-01
Abstract: PURPOSE: To ensure a start in a severely cold climate by using as many open signals as possible with an utmost possible size to just open affiliated injection valves practically for multiplex controls. CONSTITUTION: When an ignition lock 15 is operated, a clock generator 13 reports that a fuel should be delivered to start an engine 10 to an injection valve control device 14. The injection valve control device 14 evaluates whether the signal obtained from an engine temperature sensor 12 is below a temperature threshold value or not. When the signal is below the threshold value, the whole injection duration is split into multiple relatively short injection periods by the affiliated open signal. When there is an additional usable time in the operation cycle, an additional short open signal is outputted. The magnetic coil of an injection valve 11 is heated by the open signal to prevent the freezing of a valve seat section, thereby an internal combustion engine can be reliably started even in a severely cold climate.
