Title: Extension pipe and electric vacuum cleaner
Inventor: OIKAWA YOJI
IPC: A47L9/24
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To provide an extension pipe which prevents slipping out of an inner pipe by a simple structure. SOLUTION: A groove-like rail 35 is formed along the inner peripheral surface of an approximately cylindrical outer pipe 21 in the longitudinal direction. A slipping- out-preventive member 65 is fixed to a sliding end of an approximately cylindrical inner pipe 22 by a screw 39 to hold a fixing part 66 between a positioning stage 34 disposed on the inner peripheral surface of the outer pipe 21 and the slipping-out- preventive member 65. An anti-slipping-out device 68 is integrally formed with the outer pipe 21 by holding a packing 67 between the fixing part 66 and the slipping-out- preventive member 65. A stopper 86 is attached to the engaging end of the inner pipe 22 projecting outwardly from its outer peripheral surface to prevent rotation and freely slidable in the rail 35.  A stretchable concave notch 82 having inclined planes 81, 81 is formed at the end of the fixing part 66 facing to the stopper 86. When the inner pipe 22 is pulled out from the outer pipe 21 to make the length of the extension pipe 20 maximum, the stopper 86 inserts into the notch 82 to be brought into contact with the inclined planes 81, 81 to expand the diameter of the fixing part 66, which presses the outer pipe 21.

Title: Ferrite material burning method and tool material for ferrite burning
Inventor: UEDA KAZUYA
IPC: F27D3/12
Filed: 1989-10-17
Abstract: PURPOSE:To prevent the generation of abnormal crystal on the contact source of a ferrite core setter by at least partially forming an unstabilized zirconia layer on the surface of a stabilized zirconia tool material, placing a ferrite material on the unstabilized zirconia material, and burning these layers. CONSTITUTION:An unstabilized zirconia layer is formed on the surface of a zirconia tool material stabilized by CaO, MgO, Y2O3 and the like so that a calcination material may be produced. Then, a ferrite material, such as Mn-Zn ferrite core is placed on the unstabilized zirconia layer for the calcination tool material so that calcination may be carried out. This construction makes it possible to obtain a ferrite calcined material whose magnetic characteristic is more excellent compared with the case in which calcination is carried out, using an alumina setter. Moreover, the ferrite material is not placed into direct contact with the stabilized zirconia tool material, but placed on the unstabilized zirconia material layer, which prevents the generation of abnormal crystal induced by the reaction between the ferrite material and the stabilized zirconia tool material.

Title: Phase locked loop circuit
Inventor: MASUKO YASUNAO
IPC: H03L7/08
Filed: 1986-11-14
Abstract: PURPOSE:To prevent the disturbance over the stability of phase lock due to noise in an input signal by adopting the constitution in a way that only a part concentrated with phase information in an input signal of a phase comparator is extracted by a window signal formed by using a phase shift circuit so as to phase-shift to an output of a voltage controlled oscillator in a phase locked loop circuit. CONSTITUTION:A gate circuit 22 is provided to the pre-stage of a phase comparator 11 in the phase locked loop circuit 21 and the circuit 21 uses the window signal from the phase shift circuit 23 connected to the voltage controlled oscillator 13 so as to apply switch control to the gate circuit 22. For example, when a disk 5 reaches a prescribed rotating speed, the window output of the phase shift circuit 23 acts effectively on the gate circuit 22. As a result, the noise included in the input signal of the gate circuit 22 is masked by using the window output of the phase shift circuit 23 to open the gate circuit 22. Thus, the input to the phase comparator 11 has no noise and only the phase information is arranged as pulses in the signal and the phase locked loop circuit 21 applies stable operation.

Abstract: PROBLEM TO BE SOLVED: To smoothly realize the anti-lock control, the traction control, and the automatic brake control by arranging a pressure regulating piston in a hydraulic pressure chamber formed on a hydraulic pressure control device body, and controlling the pressure regulating piston making use of a cam drive mechanism. SOLUTION: When a brake pedal is stepped in, the hydraulic pressure generated in a master cylinder 1 is fed in a hydraulic pressure chamber in a brake device, and a brake piston 4 is moved to give the braking force to wheels. When the wheels are locked, and the brake loosening signal is outputted from an ECU 7, a solenoid valve 2 is locked, and a motor 6 is driven, and a cam shaft 15 is rotated through a pinion 24 and a large gear 23. A roller 23 follows cams 22a, 22b while it is rotated, and pressure regulating pistons 20a, 20b are evacuated in piston storage windows 17a, 17b. Because the volume in the hydraulic pressure chamber 12 is increased while a boot 25 is deformed, the braking hydraulic pressure is reduced, and the locking condition of the wheels is eliminated.
