Title: Vehicle steering performance controller
Inventor: YONEKAWA TAKASHI
IPC: B60G17/016
Filed: 1988-12-28
Abstract: PURPOSE:To improve response during steering transition and steering stability by changing steering properties in an over-steering direction when a turning quantity change rate is higher and in an under-steering direction when a turning quantity is higher for the same turning quantity change rate. CONSTITUTION:An electrically-operated controller 200 inputs the turning quantity signals detected by a lateral acceleration sensor 238, a steering angle sensor 240, a vehicle speed sensor 234 and so on to calculate a turning quantity change rate. The higher the turning quantity change rate is, the more steering properties is changed in an over-steering direction, and the more a turning quantity is for the same turning quantity change rate, the more the steering properties is changed in an under-steering direction. This can set the steering properties during steering transition properly according to the magnitude of the turning quantity as well as that of the turning quantity change rate, thus improving both response during turning transition and steering stability.

Title: Injection-molded heat valve gate device
Inventor: JIYOBUSUTO ARURITSUCHI JIERAAT
IPC: B29C45/16
Filed: 1991-12-16
Abstract: PURPOSE: To provide a thermal gated injection molding apparatus having melt distribution plates to allow the outer melt passage to have four radially spaced channels extending through each nozzle to a gate in a separate heated cavity forming insert. CONSTITUTION: In a multi-cavity injection molding apparatus to coinject pressurized melt from two or more melt sources, an inner melt passage extends through a melt distribution plate and an adjacent heated nozzle. The nozzle has a tapered nose which extends into an adjacent heated cavity forming insert having a gate leading to one of the cavities. An outer melt passage is separated by curved conduits on opposite faces of the melt distribution plate into four channels which are radially spaced around the central bore of the nozzle. The four channels lead to a melt funnel duct which extends in the adjacent cavity forming insert around the nose portion of the nozzle. Thus the melt from the outer melt passage is evenly distributed around the melt from the inner melt passage when they join just before entering the gate.

Title: Movement detection device
Inventor: NAKAHO JUNICHI
IPC: G01B11/00
Filed: 1994-11-30
Abstract: PURPOSE: To accurately detect the moving quantity of a transparent resin plate by projecting the light of a light emitting element on the surface in which the triangular prism of the transparent resin plate is formed and outputting a current in accordance with the position of light incident on a semiconductor position detecting element opposed to the light emitting element interposing the resin plate therebetween. CONSTITUTION: Light projected from a light emitting element 3 passes through a transparent resin plate 1 and is incident on PSD4 and however, when light passes through the resin plate 1, the light is bent by the resin plate 1 and an optical path is bent except when the light is incident on the top or the velley of a prism 2. The bent light is incident on the position of the right end P1 of a semicoductor position detecting element (PSD) 4. When the resin plate 1 is moved in A direction, the light is incident on the position of the left end 2. The change of the displacement of the position of light incident upon the PSD 4 which is changed with the movement of the resin plate 1 is converted into a pulse to obtain a pulse waveform. Since the moving quantity of the resin plate 1 is proportional to the number of a pulse, the pulse is counted to obtain a moving distance.

Abstract: PROBLEM TO BE SOLVED: To improve preservative and insect proof functions by utilizing CCA used lumber. SOLUTION: This method for constructing a promenade is to form the promenade by laying wood chips 2 on a roadbed 1. In this case, a pulverized CCA used lumber 3, which is composed by coating or impregnating CCA agent containing chrome, copper and arsenic compound in it, is used as wood chips 2 and a microorganism group is composed of an EM, as it is called, made of useful microorganism groups by positively attaching the microorganism group to the lumber chips 2. Thus, by virtue of the residual chrome and arsenic compound showing their preservative and arsenic compound functions, not only can the preservative and arsenic compound functions be improved but also mold gathering and growth of harmful insect can be certainly prevented and durability of the promenade can be prolonged.  In addition, very useful utilization of scrap wood such as a telephone pole can be contrived as such scrap wood can be used for the CCA used lumber 3.
