Title: Detecting method for crack of test piece
Inventor: FUJII TSUTOMU
IPC: G01N3/06
Filed: 1980-02-19
Abstract: PURPOSE:To enable accurate detection of the property of development of a crack by calculating a temperature compensation coefficient through measurement of the temperature by means of a thermocouple stuck to the test piece, by dividing the difference in potential on both sides of a notch by the coefficient and by converting the same to the difference in potential at the reference temperature. CONSTITUTION:The test piece 2 is housed in an ambience tank 9 of high temperature and high pressure and a load is applied thereto repeatedly by pull rods 6 and 7. The test piece 2 is fed with current by a power source device 3 and thereby the difference in potential V(t) on both sides of the notch 1 can be measured by potential- difference lead wires 4. The thermocouple 11 gives a voltage corresponding to the temperature of the test piece 2 to a converter 12, wherein the temperature compensation coefficient A(t) based on the temperature and quality of material of the test piece 2 is calculated and given to a divider 10. In the divider 10 a value of V(t)/A(t)=Vo is computed and thereby the difference in potential at the reference temperature to is calculated. By this method, the occurrence of the crack in the notch 1 owing to the repeated load and the degree of development thereof are recorded on a recorder 5.

Abstract: PURPOSE:To prevent blocking of a fuel filter due to generation of wax in diesel fuel at a low temperature and prevent deficient fuel supply at the time of starting at a low temperature without using a means such as an electric heater, so as to enhance startability of a diesel engine. CONSTITUTION:A fuel supply device is provided with a fuel passage 13 at the time of cold starting for directly supplying excessive fuel of a relatively high temperature from a fuel tank 1 to a fuel injection pump 2 through a filter 3; and a fuel passage 15 after starting for supplying the excessive fuel, which is mixed with low temperature fuel from the fuel tank 1, to the injection pump 2 through the fuel filter 3.

Title: Ignition device of internal combustion engine
Inventor: YOSHIOKA YUKIO
IPC: F02D41/32
Filed: 1991-02-12
Abstract: PURPOSE:To enhance the drivability by prohibiting ignition to any cylinder which contains lean mixture gas. CONSTITUTION:A fuel injection time calculating means P1 calculates the fuel injection time TAU according to the condition of an internal combustion engine 1, while an intake time calculating means P2 determines the intake capable time Tin in which the fuel can be inhaled into cylinder in the suction stroke of the engine 1.

Title: Output overcurrent limit circuit
Inventor: KANAMORI KIMINORI
IPC: H01L21/822
Filed: 1988-01-31
Abstract: PURPOSE:To quickly limit an overcurrent and to prevent destruction of an output transistor(TR) or a component. etc., connected to an output terminal by connecting a drain of a control TR to a gate of an output TR, connecting the gate to a power supply and connecting the source to the output terminal via a constant voltage element. CONSTITUTION:An N-channel MOS output TR 2 receiving a gate voltage from a charge pump circuit 1 is conductive and a current flows from the power supply to the output terminal 5 via the output TR 2. If any fault takes place in a load connecting to the output terminal 5, such as the output terminal 5 connecting to ground via a low resistance, an overcurrent is going to flow to the output TR 2. When a difference between the power supply voltage and the output voltage at the output terminal 5 reaches the sum between the threshold voltage of the control TR and the voltage decided by the constant voltage element 4 or over, the control TR is conductive to reduce the gate voltage of the output TR 2. Thus, the overcurrent limit is quickened and damage to the output TR and load is prevented.
