摘要:
A route guidance system for a pedestrian. An input unit inputs a departure point and a destination point of the pedestrian. A route data memory stores route data representing position and connection of each route comprising a road network. A route calculation unit calculates a route from the departure point to the destination point by referring to the route data in said route data memory. A landmark memory stores landmark data for the pedestrian's confirmation; a landmark represents a signpost of the departure point, the destination point, and the route. A landmark selection unit selects the landmark data corresponding to the route calculated by said route calculation unit from said landmark memory. A presentation unit presents a route guidance to the pedestrian using the calculated route and the selected landmark data.

A pedestrian route guide apparatus includes an input section which inputs a departure place and destination, a route data storage section for storing route data, a landmark storage section which stores a landmark, a route computation section which computes a route from the departure place to the destination on the basis of route data, a route editing section which edits the route, a landmark selector section which selects a landmark at each point on the route on the basis of the route obtained by the route editing section, a route guide text generator section which generates a route guide text on the basis of the route obtained by the route editing section and the landmark information selected by the landmark selector section, and a route text output section which presents the route guide text.

A database stores map data including road network data and landmark data. A route search unit searches for a route from a departure point to a destination point from the road network data stored in said database. A road pattern analysis unit analyzes a road pattern of the route by referring to the road network data, and obtains road pattern data as the analysis result. A route guidance information generation unit generates route guidance information of the route using the road pattern data and the landmark data along the route. A presentation unit presents the route guidance information.

In a vacuum casting method, a molding cavity is reduced in pressure to a vacuum, and when a gate is opened, a molten metal which has been raised to a molten metal retaining dome is charged into the molding cavity at a high speed. When a portion of a molten metal held in a molten metal holding furnace is raised to the molten metal retaining dome via a stalk, (1) the rising speed of a portion of the molten metal is set at 5-10 cm/sec, or (2) the rising speed is varied between an early stage of the rising motion and a later stage of the rising motion. In the latter method, the rising speed at the early stage of the rising motion is set at a speed higher than 10 cm/sec, while the rising speed at the later stage of the rising motion is set at 5-10 cm/sec. Due to the rising speed control, air involvement by the rising molten metal is effectively prevented.

摘要:
In a method of vacuum casting wherein when the molten metal previously introduced into a molten metal reservoir is fed into a cavity, the lowest head of the molten metal in the molten metal reservoir is held to be higher than the level of a sprue, so that the cycle time of casting may be shortened and the quality of cast products may be improved. To this end, the interior of the molten metal reservoir is held gas tight while the sprue is opened by a gate member of straight tubular shape.

A vacuum casting apparatus includes a plurality of pressure pins arranged in a molding cavity, and at least one pressure pin is located in a portion of the molding cavity farthest from a gate. The pressure pins are operated to pressurize the molding cavity in an order from the pressure pin located farthest from the gate to a pressure pin located nearest to the gate. A cross-sectional area reduced portion can also be formed in a portion of a runner connecting the molding cavity and the molten metal retaining dome. A molten metal in the molding cavity is thereby suppressed from flowing backward into the molten metal retaining dome when being pressurized by the pressure pins, so that the quality of the cast products is improved.

An iron golf club is one made of metal material, which is manufactured integrally through press working and gives dedication to improvement of golf club design. The head (1) has a concave portion (4) surrounded by a convex portion (6) in the backside portion (3) behind the face portion (2). Treatment for making a mirror surface is applied to the bottom portion (5) of this concave portion through press working with a fixed die (11) having a surface roughness finer than the mirror surface for which treatment for making a mirror surface is to be performed and a movable die (10). Press working of this bottom portion can be also performed through treatment for making a mirror surface with a liner member (17).
