Title: Manufacture of cast iron-made sliding member
Inventor: MORIMOTO SHIGENORI
IPC: B22D27/04
Filed: 1990-02-15
Abstract: PURPOSE:To improve the lubricity and bearing strength in a sliding member by setting a chiller at the upper part of a mold and casting molten cast iron. CONSTITUTION:At the position where the chiller 3 is set in a mold 7, as the molten cast iron is rapidly cooled by contact with the chiller 3, solidified at early time to form a rapidly cooling solidified part 9 and at this position, the primary crystal graphite 10 is prevented from float-up segregating. On the other hand, at the position where the chiller 3 is not set in the mold 7, the primary crystal graphite 10 is floated up and segregated at the most upper part in the mold 7 to form the graphite segregated pat 11 containing a great quantity of the primary crystal graphite 10. That is, on the surface part of sliding member, the graphite segregated part 11 containing much primary crystal graphite 10 and the rapidly cooling solidified part 9 are formed under mingling condition. Then, the graphite segregated part 11 has no high bearing strength by existence of the graphite 10, but gives the good lubricity on the surface of sliding member and on the other hand, the rapidly cooling solidified part 9 has high strength and improves the bearing on the surface of sliding member.

Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to well recognize whether light emitting diodes light or not from the wide range in front of a panel and to prevent the direct recognition of the shapes of the light emitting diodes. SOLUTION: Light diffusion plates 26 are disposed between the light emitting diodes 23 and window parts 18. Further, convex lens parts 29 are disposed between these light diffusion plates 26 and the window parts 18. The light emitted from the light emitting diodes 23 is diffused by the light diffusion plate 26. The diffused light is eventually transmitted through the window parts 18 toward the foci of the convex lens parts 29 by the convex lens parts 29.

Title: Prepelletizing method for raw material to be sintered enabling use of large amount of fine powder ore
Inventor: ISHII HARUMI
IPC: C22B1/16
Filed: 1993-01-29
Abstract: PURPOSE:To provide prepellets which do not degrade air permeability at the time of sintering even if a large amt. of fine powder ore is used. CONSTITUTION:The average grain sizes of the fine powder ore sticking to the surfaces of coarse grain raw materials to constitute nuclear particles and other raw materials to be sintered are determined at the time of producing the raw materials to be sintered for charging into a blast furnace by compounding the fine powder ore contg. >=80% particles of <=1mm grain size and other raw materials to be sintered with the coarse grain raw materials contg. >=50% particles having grain sizes exceeding 1mm. A void volume epsilon of the sticking powder layers is estimated from these average grain sizes and the compounding ratios of the fine powder ore and the other raw materials to be sintered with the coarse grain raw materials to constitute the sticking powder layer are so adjusted that the void volume epsilon attains <=0.45. The prepellets have high wear strength and do not collapse at the time of mixing with the other raw materials to be sintered or in the transportation process before charging to a sintering machine and, therefore, the intrinsic advantages of the prepellets are maintained and the sintered ore is produced with high productivity.

Title: Antiskid controller
Inventor: YANO AKINORI
IPC: B60T8/172
Filed: 1987-02-18
Abstract: PURPOSE:To precisely judge the car body stop timing by detecting the car body acceleration speed in braking by a G sensor (acceleration speed sensor) and installing a means which judges the stop of the car body when the car body acceleration speed exceeds a positive standard value from a negative value. CONSTITUTION:A G sensor 1 generates a voltage signal which is proportional to the magnitude of the car body acceleration speed G and posses the polarity corresponding to the direction of the car body acceleration speed G, and generates the always neative car body acceleration speed g until the car stops, in braking. Immediately after the stop of the body, swing back phenomenon is generated by the existence of a suspension mechanism, and the part directing from negative to positive is temporarily generated in the car body acceletration speed G. Therefore, in braking, the output signal of the G sensor 1 which passes through a switch 2 which is turned ON in braking is compared with a positive standard G in a comparator 3, and the comparator 3 is brought into electric conduction when the car body acceleration speed G reverses from negative to positive, and a car body stop detection signal is outputted.

Title: Ignition timing control device for internal combustion engine
Inventor: MIZUNO KAZUYOSHI
IPC: F02P5/15
Filed: 1986-02-21
Abstract: PURPOSE:To enable the ignition timing to be continually controlled to the optimum value, by calculating the ignition timing from charging efficiency calculated while air-fuel ratio is in a feedback control. CONSTITUTION:A control circuit 40, while air-fuel ratio is controlled by a feedback, calculates charging efficiency during operation from the air-fuel ratio, actually measured by a lean sensor 48, and a fuel injection quantity or the like in one operating cycle of an engine obtained from a fuel injecting time in an injector 30. While the control circuit, by a map stored in a memory 40b, calculates ignition timing from an actually measured engine speed and the calculated charging efficiency. In this way, even if the correlation between an intake pipe negative pressure and intake air quantity-engine speed ratio and the charging efficiency is generated by a tappet clearance error, intake system leak, other change of an engine characteristic and a running condition, the ignition timing can be continually controlled to the optimum value.
