Title: Method and device for production of semiferrite stainless steel strip from molten metal
Inventor: FUIRITSUPU DOUMARE
IPC: C21D1/607
Filed: 1991-08-13
Abstract: PURPOSE: To prevent the generation of austenite when a semi-ferritic stainless steel strip is produced from molten metal. CONSTITUTION: In an ingot mold for continuous casting having two cooling rolls 2 disposed by mutually facing so as to demarcate a casting space and rotating mutually in the reverse direction, the metal is solidified and the solidified metal strip 3 is continuously drawn out from the ingot mold and such sufficiently quenching as to prevent the generation of austenite is executed by bringing the strip into contact with a quenching medium 6 at the lower side of the ingot mold. The cooling medium is formed as quenching bath held in a container having a passing-through holes 5 for the solidified strip 3 at the bottom part positioned at the lower side of the rolls, or liquefied inert gas is jetted onto the cast product with a nozzle. In this way, since the obtd. steel strip scarcely contains martensite in the ferritic matrix, the shearing and the coiling can easily be executed at the last stage in the casting process.

Title: Ignition timing control apparatus
Inventor: KATOUGI KOUZOU
IPC: F02P5/153
Filed: 1987-09-14
Abstract: PURPOSE:To improve the accuracy of ignition timing control by detecting the point of maximum pressure in the explosion stroke of each cylinder and obtaining the crank angle giving a real peak through interpolation along successively adjacent sampling points by means of a high-order function coupling those sampling points together. CONSTITUTION:In an internal combustion engine with multiple cylinders, an instantaneous pressure can be sampled through such a process as the pressure of each cylinder detected by each pressure sensor 5 is multiplexed by a cylinder switching multiplexer 3 and converted by a high speed AD 2. The crank angle giving a maximum point is obtained through interpolation along (n) spots of sampling point by means of a high-order function. The maximum point for each cylinder obtained through interpolative calculation by a micro-computer 1 is memorized in RAM. When the maximum point advances, the ignition timing is delayed against knocking. And when the differential valve around the maximum point is smaller than the valve appering in normal combustion time, it is judged as abnormal combustion. The angular resolution for detecting the peak point by this control apparatus can be made higher than the resolution of a crank angle sensor, so that the control accuracy is improved.

Abstract: PURPOSE:To make smaller the electrostatic capacity between the leads of the title package than that of a glass-ceramic sealing package by a method wherein an organic substance paste is applied on the 4 sides of the lower surface of a cap for fixing the cap on a lead frame and a substrate. CONSTITUTION:A semiconductor element 1 is put on a substrate 3, a low-melting point glass 4 is applied on the 4 sides of the substrate 3 and a lead frame 2 is welded on the glass 4.

Accordingly, the electrostatic capacity C between the leads of a package is almost proportioned to the specific permittivity of a dielectric encircling the leads. Thereby, as the material covering the upper halves of the leads is constituted of the organic substance paste, the capacity C is decreased.
