Title: Neutral position detection device
Inventor: KAWAGUCHI MASAO
IPC: B62D15/02
Filed: 1994-10-28
Abstract: PURPOSE: To prevent the generation of a great error accompanying the correc tion steering, etc., regarding a neutral position detection device which is suitable for detecting the neutral position of a steering wheel in a running vehicle. CONSTITUTION: A steering count value increasing or dicreasing according to the steering angle of a steering wheel is obtained. The MAX/MIN of the steering angle peaks to the right and left are detected based on the increase/decrease tendency (steps 100-1 14). When the MAX/MIN are detected continuously within a specific period, only the last peak is made valid (steps 118 and 120). The MAX/MIN which are not detected near the straight-advance state and are not continuously detected are adopted as the continuous detection of MAX or MIN are adopted as the PKH(right peak) and PKL(left peak), respectively (steps 122-132) as the basic data of neutral position operation.

Filed: 1988-10-24
Abstract: PURPOSE:To control the supply amount of a medium to the optimum value by providing a means for forcibly imparting contraction force to a bellows mechanism for adjusting the relative positional relation between the beam converging position of an ultrasonic wave or a shock wave and a region to be treated. CONSTITUTION:Since contraction force always acts on a bellows mechanism 4 by a contraction force generation means 12, the tension corresponding to the internal pressure of an applicator 1 is generated in the flexible diaphragm 5 provided to the leading end part of the bellows mechanism 4. By this constitution, even in such a state that the bellows mechanism 4 is contracted shortly like a case treating the object 1 to be treated at a deep region, the diaphragm 5 can be brought into contact with a living body 10 under sufficient pressure and the energy of an ultrasonic wave or a shock wave is not reflected or attenuated and the region 11 to be treated is effectively irradiated with said energy. Further, by utilizing that the contraction force imparted by the contraction force generation means 12 corresponds to the length of the bellows mechanism 4, the length of the bellows mechanism is measured and the supply amount of a medium 8 to the applicator 1 is controlled on the basis of the measured result to obtain the optimum supply amount of the medium corresponding to the length of the bellows mechanism.

Abstract: PURPOSE:To supply nails to a nailing machine without impairing the nails and without wearing members on the nail supply device side, by providing a compressed air jetting part which jets out compressed air for sending under pressure the nail released from holding to a hammerhead part and checks supply of the subsequent nail temporarily. CONSTITUTION:The head part 22 of the foremost nail 23a sent to a nail holding part 24 is supported by a step part 38 of a nail holding member 32 constituting the nail holding part 24 and is held thereby temporarily. By an operation of a nail holding member driving mechanism 31 constituting the nail holding part 24, thereafter, the nail holding member 32 is rotated around a shaft part 36 in the upper end part thereof, so as to cancel holding of the nail 23a. Meanwhile, a compressed air jetting pipe 33 jets out compressed air to the nail 23a almost simultaneously with the release of this nail 23a. As the result, the nail 23a is carried to a hammerhead part at a high speed through a nail supply tube, through the intermediary of an introducing port 64. Then, the nail holding member driving mechanism 31 operates to rotate the holding member 32 counterclockwise and to make it return to the original position, where it holds a subsequent nail 23b temporarily.

Title: Discriminating method for original text of magnetic recording medium
Inventor: SANBE YOSHIO
IPC: G11B20/00
Filed: 1984-12-19
Abstract: PURPOSE:To prevent substantially both the reproduction of a floppy disk and the rewriting of a data field part by recording an ID field part and a data field part continuously to a floppy disk serving as an original text and detecting a shift of phase at a junction between both field parts to decide the identity of the original text. CONSTITUTION:A shift of bit is produced in the read data obtained at and after the junction between the start and end points of a data field part owing to a shift of phase at the junction. Thus it is possible to decide whether a floppy disk is identical with an original text or a copy or obtained by rewriting the data contents of the original text by detecting whether or not a shift of bit is produced in a data read mode. It is also possible to detect the bit shift by comparing the read-out information on the floppy disk with the information on the original text stored previously. The probability showing the phase shifts produced at the start and end points of the data field part is equal to 1/8 per sector. Thus a large number of sectors to be checked provide higher accuracy.
