Abstract: A diode manufacturing method provided herein includes first-third implantations and a heating. The first implantation implants n-type impurities into a first range at a first depth. The second implantation implants n-type impurities into a second range including the first range as a part at a second depth shallower than the first depth. The third implantation implants p-type impurities into a third range located on both sides of the second range at a third depth shallower than the first depth at a density higher than the second implantation. The semiconductor substrate is heated in the heating so that a first p-type region (contact region) is formed in the implanted region in the third implantation and a first n-type region (pillar region) is formed in a part of the implanted region in the first and second implantations.

Abstract: A voltage generator used to generate a voltage for driving a vehicle fuel injector includes a microcomputer, a coil, and a capacitor. The microcomputer calculates an interval at which the fuel injector is driven. When the interval is less than or equal to a predetermined time period, the microcomputer causes a first current to flow through the coil so that the capacitor is charged to a first level by counterelectromotive force produced in the coil. When the interval is greater than the time period, the microcomputer causes a second current less than the first current to flow through the coil so that the capacitor is charged to a second level less than the first level. The fuel injector is driven by the capacitor voltage.

Abstract: A microcomputer calculates a fuel injection time. When the fuel injection time is longer than a predetermined specified time, the microcomputer sets a voltage level of a short-term injection signal to high and sets a peak current for coils in fuel injectors to a first peak current. When the fuel injection time is shorter than or equal to the predetermined specified time, the microcomputer sets a voltage level of the short-term injection signal to low and sets a peak current for the coils to a second peak current smaller than the first peak current.

Abstract: A solenoid valve driver is provided which may be employed in automotive fuel injection system. The solenoid valve driver includes a capacitor which is to be discharged to energize a coil of a solenoid valve and a controller. The controller determines a discharge start time that is a time when the capacitor is to be started to be discharged to energize the coil of the solenoid valve. When the discharge start time is reached in a condition that a charged voltage of the capacitor is out of a target voltage level, the controller advances the discharge start time to eliminate a lag of operation of the solenoid valve.

Abstract: When both the IABP and the PCPS are used, they exhibit an excellent circulation assisting effect. In this case, however, sequela such as hypoxic encephalopathy may well occur after the heart failure is remedied. The invention provides an intraaortic balloon catheter capable of preventing such sequela. The balloon catheter of the invention includes a catheter main body part which is to be inserted into an aorta, and a balloon section formed on an outer peripheral portion of the catheter main body, to be inserted into the aorta together with the main body, and to be expandable and contractible in the aorta under the control of the IABP. An end portion of the catheter main body functions as an introductory portion of the catheter, and has a blood feed hole formed therein for introducing, into an artery such as the aortic arch, arterial blood of high oxygen concentration fed from a circulation assisting unit such as the PCPS.

Abstract: A cardiopulmonary function assisting device includes a gas guide tube of which peripheral wall does not transmit gas or liquid such as blood and has a suitable rigidity and a suitable flexibility. A header is coaxially attached to an opening at the distal end of the gas guide tube. A plurality of balloons are attached to the distal end of the header. The balloons are formed of a gas permeable film and left in a blood vessel. Oxygen is supplied to the balloons through the gas guide tube, thereby expanding the balloons; oxygen is discharged from the balloons, thereby contracting the balloons. The expanding and contracting operations are repeated. As a result, when the balloons are expanded, oxygen is transmitted through the balloons and added to blood on the periphery of the balloons and the expanded balloons remove the blood away from the periphery. When the balloons are contracted, the periphery of the balloons is filled with blood.
