摘要： PROBLEM TO BE SOLVED: To solve the problem that hydrogen having invaded into a pressure and differential pressure transmitter from outside or internally generated hydrogen and hydrocarbons turn into foams in a pressure guiding path to invite drifting of indicated values and failure to output accurate values.SOLUTION: In a pressure and differential pressure transmitter in which a pressure guiding path encloses sealing liquid for transmitting pressure, a space is to be formed between a diaphragm and a body side wall face. The pressure guiding path is connected to the body side wall face, and a pressure received by the diaphragm is transmitted to a sensor via the sealing liquid enclosed in the space and the pressure guiding path. The configuration is such that a hydrogen adsorbing material for adsorbing hydrogen atoms in the sealing liquid is disposed at least in the sealing fluid, the body side wall face or part of the area extending from the body side wall face to the sensor.

摘要： PROBLEM TO BE SOLVED: To increase an input current and sufficiently assure the input current necessary for the ON-operation of an IGBT in a drive circuit (such as the drive circuit of an ignition device for internal combustion engine) for a car using a power element with IGBT. SOLUTION: This drive circuit 20 comprises the IGBT 21 as the power element allowing a primary current to flow through and cut off the coil of an ignition coil. A pull-down impedance (variable impedance circuit 32) allowing the input current to intentionally flow to the GND after bypassing the IGBT is installed on the input stage of the drive circuit 20. The pull-down impedance becomes a high impedance before the IGBT 21 is completely turned on and becomes a low impedance in an area where the IGBT 21 is completely turned on.

摘要： PROBLEM TO BE SOLVED: To provide a one-chip igniter having high reliability. SOLUTION: A power unit and a control unit are integrated with one chip in an IGBT monolithic silicon substrate. A control circuit unit is a current restricting circuit for preventing current flow having a set value or more, and has a function for forcibly shutting out primary current by detecting abnormal heating. Energy charged in an ignition coil is discharged by repetitively generating secondary voltage of an ignition coil with plug discharging voltage and less so as to prevent generation of spark discharge on an ignition plug when current is forcibly shut out. It is thus possible to provide the one-chip igniter having high reliability.

摘要： PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine which can constitute a switching circuit part and a control circuit part on one semiconductor chip and can also produce number effect by fitting its specification to a most-multiple-function-type igniter. SOLUTION: A switching circuit 60 for controlling primary current by conduction or cutoff is constituted with an IGBT(insulated bipolar transistor) 61, vertically-structured insulation-gate-type bipolar transistor which has a Zener diode 63 for voltage clamp between collector gates, and a control circuit 50 is constituted in a same chip as the IGBT 61 using a dielectric separating substrate. Therefore, the switching circuit 60 and the control circuit 50 can be integrated into one chip without receiving mutual effect between any elements, and the specification of the ignition device is easily fitted to that of a most- multiple-function-type ignition device.

摘要： PROBLEM TO BE SOLVED: To prevent stress at wirebonding from influencing elements on their lower part by specifying the thickness of a wirebonding pad or the equivalent means connecting together semiconductor switching elements, external circuits, terminals, and the like.

摘要： PROBLEM TO BE SOLVED: To prevent re-energization during the presence of a self-diagnosis and an ignition on-control signal by forming a bipolar transistor for controlling the current-energization interception of a primary current, a current limiter circuit and a thermal shutoff circuit forcibly shutting off the primary current in time of something wrong happening, into on a chip. SOLUTION: An ignition circuit 11 is provided with a bipolar transistor (IGBT) 2 energizing or intercepting a primary current flowing into a primary coil of an ignition coil 1. A current limiter circuit 4 controls the extent of gate voltage by a current detector 3, limiting the primary current to the setting value, while a thermal shutoff circuit 5 makes the primary current be forcibly shut off or reset according to a condition. This ignition circuit 11 is made to serve as an integrated circuit which converges the bipolar transistor (IGBT) 2, the current limiter circuit 4 and the thermal shutoff circuit 5 on one chip intensively. A chip's detection temperature is reached to the initial setting value, a latch circuit 6 is set up, and thereby an ignition control signal is maintained up to a time when it is turned to OFF from ON.
