Abstract: PURPOSE:To contrive facilitation of handling, at the time of inversion, with a single seat inverted longitudinally to be made usable by turning the seat about the center of a horizontal shaft in a post upper part to vertically place a seat part, next turning a post about the center of a vertical shaft thereafter rotating the seat about the center of the horizontal shaft. CONSTITUTION:When a front part side is lifted by pulling a knob part 52 to the front to unlock a seat 8, a side plate 26 is rotated integrally with the seat 8 around a horizontal shaft 25 in the clockwise direction. When a seat part 10 is turned to a vertically placed condition, the seat 8 is supported onto the side plate 26 with the seat part 10 in the vertically placed condition because a side plate lock means engaging part 70 is engaged with an engaging part 71.

Title: Doughnut-shaped metal dust core
Inventor: UEDA YOSHIO
IPC: H01F41/02
Filed: 1990-11-20
Abstract: PURPOSE:To obtain a thin doughnut-shaped metal dust core with an effect for improving magnetic permeability improved considerably better than conventional ones so as to eliminate need of increasing thickness even if an average diameter of the core is increased with coil winding operativity taken into consideration by setting a relation between width and thickness of a cross section at a specific ratio. CONSTITUTION:A doughnut-shaped metal dust core 2 of this example has a relation between width W and thickness H of a cross section of W=1.7 to 2.5H. The doughnut-shaped metal dust core 2 is molded by putting metal dust or the like in a doughnut-shaped recessed groove 3 of a fixed lower mold 4, lowering a core mold 6 and a ring mold 7 toward the lower mold 4 and applying large pressure. Since the metal mold pressure at the time of molding the metal dust core is sufficiently applied to inside of the metal dust core due to a thin core, density of the metal dust core is improved and magnetic permeability is improved. Thus even if an average diameter D increases, it is not necessary to increase the thickness H intentionally thereby first realizing a thin core.

Title: Air intake control valve device for engine
Inventor: NAGASHIMA YOSHIBUMI
IPC: F02D9/02
Filed: 1989-12-08
Abstract: PURPOSE:To make the combustion state desirable by providing a stepless switching mechanism for switching a control valve interlockingly with the opening position of a throttle valve, and opening the control valve to full admission regardless of the switching mechanism at the time of air intake negative pressure becoming lower than the set pressure. CONSTITUTION:In a low speed region of an engine, a control valve 16 closes one intake passage 9 so that intake air is sent into a combustion chamber through the other passage 8. As the passage 8 has a small diameter, the intake air flows at high speed, and powerful swirls are generated. Before a throttle valve 2 is gradually opened and the demand air quantity reaches the limit of air quantity surged in the low speed air passage 8, the control arm 23 of a stepless switching mechanism 26 presses a lever 25 to rotate a control valve stem 14 to open the control valve 16. A control lever 22 and the control arm 23 are so designed that the control valve 16 is opened to the half-opened position of an appropriate angle from its fully opened position during the time of the throttle valve 2 reaching the fully opened position from its opened position at that time. Accordingly, the lowering of torque and the defective combustion state are not generated, and this makes engine operating performance desirable.
