Title: Knocking controller
Inventor: MAKINO TADAYOSHI
IPC: F02D45/00
Filed: 1984-05-22
Abstract: PURPOSE:To keep off a misjudgment of knocking due to variations in mid-point potential, by measuring the mid-poing potential of sensor output periodically, while performing various operations and knocking judgments on the basis of this measurement. CONSTITUTION:The mid-point potential V0 outputted out of a bias circuit 4 during a bias gate period by means of a bias gate signal generating device 26 is inputted into a comparator 13 via an analog switch 11C, converted into analog-to- digital conversion at a microcomputer 12, and is stored in a knocking judging level calculation device 21. And, at this knocking judging level calculation device 21, a knocking judging level is calculated on the bas is of the A/D converted mid-point potential, and knocking is judged after being compared with the output of a sensor 1. Therefore, even in time of engine low speed and the sensor output being small, the equalized output of the sensor and a level of the sensor output are accurately measurable, thus an accurate knocking judgment is performable.

Title: Thermal conducting pipe for heat exchanger
Inventor: MINAMOTO KENKI
IPC: F28F19/04
Filed: 1989-04-21
Abstract: PURPOSE:To obtain a superior anti-corrosion characteristic of a protection film and its anti-fouling characteristic by a method wherein a coated film having a predetermined amount of a silicon resin of lower specific weight than that of a coating material with epoxy resin dispersed as major component is made to be lined on an inner surface of a pipe. CONSTITUTION:As silicon resin having a lower specific weight as compared with that of an epoxy resin coating is used, some coroid particles of silicon resin are normally placed at a coating surface due to a Braun movement, resulting in that the coated surface is seemed to be covered by the silicon resin. Due to this fact, a contact angle of the coated film in respect to water is increased and an anti-corrosion characteristic is remarkably improved. An amount of addition of silicon resin is defined as 1 to 30wt.%. In case that the adding volume is less than 1wt.%, it is not possible to set the contact angle of the coated surface with respect to water to a predetermined value and then an anti-fowling effect may not be attained. In turn, if the adding amount exceeds 30wt.% a tight contact between the coated film and a mother metal is lowered. In addition, if the contact angle of the coated surface with respect to water is more than 80 deg., a superior anti-fowling effect can be attained even if a low speed water is used.

IPC: A61K6/893
Filed: 1988-04-28
Abstract: PURPOSE:To obtain a dental resin containing residual NCO and giving a polymer having low water-absorption, by reacting a mono- or polyhydroxy compound containing ethylenic unsaturated bond with excess polyisocyanate. CONSTITUTION:The objective dental resin containing 1-2% of residual active NCO group can be produced by reacting a mono- or polyhydroxy compound having ethylenic unsaturated bond (e.g. 2-hydroxyethyl methacrylate) with a polyisocyanate (e.g. trimethylhexamethylene diisocyanate) at an NCO/OH equivalent ratio of 1.01-1.2. The resin is a monomer having 1-4 ethylenic unsaturated double bonds per 1 molecule on an average. Since the polymer derived from the monomer has low water-absorption, there is no problem such as the swelling deformation of the resin, deterioration of the durability and the proliferation of bacteria in absorbed water.
