IPC: B23K33/00
Filed: 1986-12-26
Abstract: PURPOSE:To prevent the formation of bulging of a metal plate by providing plural through holes or the groove passing to the end face on a metal plate via a gap and joining to the base body composed of a metal or ceramics. CONSTITUTION:In case of joining a metal plate 10 and the base body 12 composed of a metal plate or ceramics by the molten body due to a heating eutectical reaction plural through holes 11 or the groove passing to the end face is formed at certain or uncertain intervals on the metal plate 10.

Title: Degumming of vegetable oil with enzyme
Inventor: HENINGU BUUHORUTO
IPC: C11B3/00
Filed: 1994-11-21
Abstract: A process is disclosed for enzymatically degumming vegetable oil where the vegetable oil to be degummed is adjusted to a pH from 3 to 6 and is mixed with an aqueous enzyme solution, which contains one of the enzymes phospholipase A1, A2 or B. In a degumming reactor the enzymes are permitted to act on the oil at temperatures from 20 DEG  to 90 DEG  C. with stirring. Before or after a separation of the degummed oil a separation promoter or a solubilizer is added at temperatures from 20 DEG  to 90 DEG  C. to the liquid which has been withdrawn from the degumming reactor. A substantially sludgefree solution, which contains used enymes, is thus recovered and is recycled at least in part to a location preceding the degumming rector. The content of recycled used enzymes in the total amount of the enzymes dispersed in the oil is at least 10%.

Title: Controller for on-vehicle power generator
Inventor: TSUTSUI TOSHIO
IPC: H02J7/16
Filed: 1993-11-17
Abstract: PURPOSE:To always keep a battery well charged even when the power generating margin of a power generator varies by adding a prescribed delay time to the target generated voltage value of the generator at the time of returning the target value to an original low value when the rotating speed of the generator becomes lower than a prescribed speed and, at the same time, the power generation factor of the generator becomes lower than a prescribed value while the target value is changed to a higher value. CONSTITUTION:In case the power generation factor of a power generator 1 detected by a power generating factor detecting circuit 4 is higher than a prescribed value when the charging of a is battery 6 is controlled by setting the target generated voltage value of the generator 1 at a low level, a CPU 51 identifies the possibility of discharging front the battery 6. When the cumulative time of such a state exceeds a fixed value, a target value changing circuit 5 changes the target generated voltage value to a higher value so that the battery 6 can be charged quickly. When the rotating speed of the generator 1 detected by an engine speed detecting circuit 2 is lower than a prescribed speed and the power generation factor of the generator 1 is smaller than another prescribed value, the circuit 5 returns the target generated voltage value to the original value. When the value is returned to the original small value, a generated voltage control. circuit 3 adds a prescribed delay time to the target generated voltage value.

Filed: 1987-12-08
Abstract: PURPOSE:To miniaturize a transmission case and improve the degree of freedom at a change lever by forming a select shift case and a lever support case on the top of a transmission case and linking a select shift shaft to a change lever through an intermediate shaft. CONSTITUTION:A select shift case 20 and a lever support case 26 are positioned on the top of a transmission case 4.

Title: Device for deciding deterioration of oxygen sensor and engine controller having this device and display panel device
Inventor: ISHIKAWA HIDEAKI
IPC: G01R31/00
Filed: 1988-12-12
Abstract: PURPOSE:To exchange an oxygen sensor before the deterioration thereof exerts adverse influ ence on the driving performance by determining the difference between the max. output value and min. output value of the oxygen sensor at every traveling of a vehicle for a pre scribed distance or determining the change rate in this difference, comparing the difference or change rate with a prescribed value and deciding the presence or absence of the deteriora tion. CONSTITUTION:The opening degree of a throttle valve increases to increase the suction air quantity and the basic pulse width increases so that a large volume of fuel is injected and supplied to the engine when an accelerator pedal is treated to accelerate the engine during the traveling of the vehicle. The fuel rich state is then attained and the output voltage value of the oxygen sensor 5 attains the max. value V2. On the other hand, the throttle valve is closed to decrease the suction air quantity and the basic pulse width Tp decreases as well when the engine is rapidly decelerated. The injection pulse width Ti usually fuel lean at the time of fuel supply stop and the output voltage of the sensor 5 attains the min. value V1. This difference V2-V1 decreases as the sensor 5 is deteriorated. The presence or absence of the deterioration is, therefore, decided by comparing this difference or the change rate thereof with the prescribed rate. The exchange of the oxygen sensor before the deterioration exerts adverse influence on the driving performance is possible.

Filed: 1991-10-30
Abstract: PURPOSE:To enable a reflow soldering operation to be substantially executed by local heating by a method wherein a soldering auxiliary layer is formed of ceramic material which contains rare earth elements, Ba, Cu, and O. CONSTITUTION:A soldering auxiliary layer 4 is formed of ceramic material which contains Y1Ba2CU3Ox, Ho1Ba2CU3Ox, Re, Ba, Cu, and O (Re denotes rare earth element). In a circuit board, as the soldering auxiliary layer 4 absorbs infrared rays, a connecting metal pad 31 surrounded with the soldering auxiliary layer 4 is especially heated at reflow soldering and heated to a higher temperature than the other parts. Therefore, even if the connecting metal pad 31 is heated to a suitable temperature for soldering, the other part is heated to a lower temperature than the metal pad 31. Therefore, a circuit board equipped with the soldering auxiliary layer 4 of this design can be subjected to a reflow soldering process by local heating. By this setup, a reflow soldering operation can be substantially carried out by local heating.
