Title: Brake holding device
Inventor: NAKAGAWA KEIJI
IPC: B60T11/10
Filed: 1983-11-18
Abstract: PURPOSE:To enable control of braking during failure in operation, by a method wherein, in a titled device which is adapted to be operated in linkage with operation of a clutch device so as to facilitate the starting of a vehicle on an ascent road, a valve device is held in an opening state through operation of a switch in linkage with excess movement of a control shaft. CONSTITUTION:A titled device is braked in a way that, when a vehicle is brought to a stop on an ascent road, working liquid, generated from a master cylinder through pedalling of a brake pedal, is supplied from connecting holes 7 and 8 to each wheel cylinder through valve devices A, B and connecting holes 9 and 10. A shaft part 19 of a plunger 15 is moved aside from a valve seat 16 with a cam 11 moved rightward through rotation of a control shaft 12 in linkage with disengaging control of a clutch through a wire 54, and a valve member 20 is seated on a valve seat 16 under gravity, and this hols a liquid pressure on the wheel cylinder side. In which case, when the control shaft 12 is excessively rotated due to some cause, such rotation is detected by a switch, not shown, and with an electromagnet 24 excited, a valve device B is held in an opening state.

Title: Guided missile
Inventor: HASHIMOTO TAKEO
IPC: F42B10/60
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To perform a rolling control by steering wings in a simple structure by arranging the steering wings at a front part of a fuselage and stabilizing wings at a rear part, and supporting a lift surface to a flat surface including a central axis of the huselage and radially overhanging the lift surface from a surface of the fuselage to support it in a T shape. SOLUTION: The missile 31 comprises a lift surface 32 at a rear part of a body, struts 33, and steering wings 34 rotatably supported around a steering shaft perpendicular to an airframe axis. The surface 32 is fixed to a T shape by the struts 33 to constitute stabilizing wings 35. The wings 34 and 35 are mounted one by one at positions equally divided into four from an outer periphery of the fuselage. When the wings 34 take a rolling angle 6, a lift L6 is generated at each wing 34, a uniform flow is bent by ε from a longitudinal direction of the fuselarge at a rear side of each wing 34 to become an obliquely rearward direction from the longitudinal direction. Even when the surface 32 of each wing 35 is bent by the ε, no lift is generated, and a lift L7 is generated reversely to the wing 34.  Since the L7 is smaller than the L6 and a rolling moment is generated in a rounding direction around a longitudinal axis, the missile 31 is rolling-controlled.
