Abstract: Personal watercraft to be test is set in a water tank. Water flow guide plate is positioned, rearward of the stern of the watercraft, for guiding a water jet from the watercraft to make a U-turn toward a front portion of the watercraft. Vertical partition plate is positioned, centrally of the width of an underwater portion of the tank, for directing the water jet to horizontally circulate around the partition plate. In another example, water flow guide plates are provided, at four corners of the underwater portion, for sequentially guiding the water jet from the watercraft to form a vertical circular water flow, and a horizontal partition plate is provided, centrally of the height of the underwater portion, for directing the water jet to vertically circulate around the partition plate.

Abstract: A small planing watercraft manufacturing system includes a hull loading station, an engine mounting station, an adhesive applying station, a deck assembling station, a clamping station, a curing station and a watercraft unloading station that are disposed in a closed loop-shaped travel path in the order named with the hull loading station and the watercraft unloading station located adjacent to each other. By virtue of the closed loop-shaped travel path, the manufacturing system requires only a small space for installation thereof, can be constructed at a relatively low equipment cost and is able to produce small planing watercrafts with increased efficiencies.

Abstract: A thrust measurement system includes a water pool for receiving therein a watercraft in a floating condition, a bow holding apparatus disposed on an edge portion of the water pool for holding a bow of the watercraft, a thrust measurement device mounted in the bow holding apparatus, and an anchoring device spanning between an edge of the water pool and a hull of the watercraft for anchoring the watercraft in position against swinging movement about the bow. In order to permit free rise and fall of the bow of the watercraft, the bow holding apparatus has a floating structure that can move freely in a vertical plane.

Abstract: An apparatus for manipulating a transmission of a vehicle, wherein speeds of transmission for the vehicle can be switched-over both automatically and manually, is provided which makes it possible to use the same switching unit for detecting whether a shift lever is positioned on a first path side at which an automatic transmission mode is executed, or on a second path side at which a manual transmission mode is executed, even if the design of the shift lever or other parts of the apparatus are changed. The apparatus includes a switching unit 5 for detecting on which side the shift lever 1 is positioned, the first path 2 side or the second path 3 side. The switching unit 5 has a first manipulating member 52 connected with a connecting portion 11 of the shift lever 1. The first manipulating member 52 is constructed so as to be a sliding bearing so that it can pivot freely around an axis O thereof.

Abstract: A gearshift apparatus having a shift lever is constructed so that the transmission stage can be set or changed by manual operation when the shift lever is moved from a main gate for an automatic transmission mode to a manual gate for a manual transmission mode through a transit gate. The apparatus comprises a detent unit attached to the body of a vehicle. The unit contains a moving member for selection therein. The moving member moves integrally with the shift lever when the lever moves in the transit gate. When the lever moves in the main gate or the manual gate, the moving member never follows the motion of the lever. The detent unit is provided with a retaining mechanism for producing a retaining force for retaining the shift lever and a click feeling at either end of the transit gate as the lever moves along the transit gate. The shift lever has a simple construction, although it is provided with all necessary functions for the change between the automatic and manual transmission modes.

Abstract: A power seat switch for use in a power seat system of a vehicle for electrically regulating a position and reclining posture of a vehicle seat. The power seat switch comprises a terminal block 1, a printed circuit board 2, module switches 3, an inner case 4, a first moving plate 5, a second moving plate 6, a case 7, a seat knob 8, and a reclining knob 9. The seat knob 8 and the reclining knob 9 are engaged with a plurality of protrusions 52, 62 extending from the first moving plate 5 and the second moving plate 6 and are mounted by superposing the knobs 8, 9 on the case 7. The terminal block 1 includes a connector housing 11 integral therewith. The plurality of module switches each have the same shape and are mounted on the printed circuit board 2 with different orientations. The power seat switch having this structure is small and inexpensive and can be easily mounted in a vehicle.

Abstract: A connection structure connecting an end of a distribution cord on a shift lever to an end of a distribution cord on a device main body. The connection structure provides electric conduction, for example, with a switch disposed on a control knob of a shift change lever device. The structure includes a control knob having a grip portion and a switch or the like disposed on the control knob. The control knob is securely connected and integrated by axial fitting to the upper end of a driving base pivoted swingably at a lower end. A conducting flange is molded integrally with the driving base near an upper end of the driving base. Connecting conductor male terminals protrude from a lower end of the grip portion and are electrically connected with the switch. Connecting conductor female terminals are fitted into the conducting flange at respective positions opposing to the connecting conductor male terminals and are connected with the distribution cord on the device main body.
