Title: Member fixing tool
Inventor: OSADA YOSHIMASA
IPC: F16B15/04
Filed: 1993-09-24
Abstract: PURPOSE:To prevent destruction of a layer into which a member fixing tool is driven by providing a flange at one end of a cylinder main body, a pointed section at the other end of an outer cylinder which has a hole in the vicinity of the other end, a shaft which is inserted from one end of the outer cylinder, an anchor member whose the other end faces the hole of the outer cylinder, and a detachable spacer cylinder between the flange and the shaft head and forming a positioning recessed section on the anchor member. CONSTITUTION:When a head 2b of a shaft 2 is hit, an outer cylinder 1 and the shaft 2 become integral with a spacer cylinder 6, and the outer cylinder 1 is driven down to a flange lb and stops The outer cylinder 1 is compressed by the head 2b. Force by force in the direction of radius on a thick wall section 6a is generated in the upper section of a spacer cylinder 6 on an inclined face 6c of the spacer cylinder 6 and a tapered face 2c of the shaft 2 with a shaft core as a boundary. The spacer cylinder 6 is broken as shown by a virtual line and comes off from the shaft 2. Since there is a positioning recessed section 2d on a lower end face of the shaft 2, axial lines of the shaft 2 and the anchor member 4 coincide and are held, and the anchor member 4 goes out of a hole 1c of the outer cylinder smoothly to take a well-balanced posture and becomes an anchor which opposes to pull-out force of a nail. As a consequence, the surrounding of a layer into which a member fixing tool is driven is not improperly destructed.

Abstract: PURPOSE:To enable diagnosing malfunctions of a dynamic quantity detection means properly without affecting the detection range oft he dynamic quantity by generating electricmotive force with electrostatic induction. CONSTITUTION:The electric charge obtained as a piezoelectric effect by acceleration give to an piezoelectric body 1 is output to an amplifier 7 as an acceleration signal. The signal from an oscillator 5 due to its driving is amplified in a booster coil 13, cut at the direct current signal part and impressed as a high frequency high voltage to an electrode 11 of a stage 5 and resultantly, a voltage with high inductance is induced between two electrodes of the piezoelectric body 1 by the alternating electric field. As this changes with the abnormality of the piezoelectric body 1 and the like, malfunction can be diagnosed. The acceleration signal mixed and output by the amplifier 7 and the malfunction diagnosing signal are separated with a low-pass filter 17 and a band-pass filter 9, respectively. Based on these signals, the malfunction diagnosis and dynamic quantity calculation are performed with an arithmetic processing means. Thus, using the induction voltage caused by electrostatic induction independent of the voltage generated by acceleration, proper malfunction diagnosis can be done.
