Title: Slow-away-type twist drill
Inventor: TEI KOUHITSU
IPC: B23B51/00
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To prevent abrasion of a chip discharge groove by notching a carbide heel portion of the chip discharge groove along torsion, and joining cemented to the notch to be on one and same surface in the chip discharge groove. SOLUTION: A chip discharge groove 2 having torsion extends in the axial direction at one end of a round bar shaped drill body 1. The heel portion 6 of the drill body 1 is notched along the torsion of the chip discharge groove 2, and a twisted bank-like cemented carbide 7 is joined to the inside of this notch. Simultaneously, the cemented carbide 7 is joined so that wall surfaces of the chip discharge groove 2 are on a same surface. An oil hole 8 that communicates from the rear end and opens at the tip is drilled in the drill body 1. During cutting, chips are discharged outward together with cutting liquid supplied from the oil hole 8 through the chip discharge groove 2 as a flow passage.  Flowing-out of the chips in this drill is smooth, and abrasion of the chip discharge groove 2 by grazing of the chips is restrained by existence of the cemented carbide 7 having good abrasion resistance.

IPC: G11B5/02
Filed: 1988-06-03
Abstract: PURPOSE:To reduce the area of a pair of rotary transformers and to miniaturize a device by making the contact angle of a magnetic tape wound to a pair of cylinders into 180 deg. or below and making it smaller than the opposed angle of two magnetic heads. CONSTITUTION:One winding 12 is serially connected to two magnetic heads 7 and a rotary transformer 9 at a rotation cylinder side concentricly and a closed circuit is formed. A contact angle beta of a magnetic tape 17 guided to a guide roller 16 wound to a rotation cylinder 6 is 180 deg. or below and an opposed angle alpha of a pair of magnetic heads 7 loaded on the rotation cylinder 6 is larger than the contact angle beta of the magnetic tape 17. Thus, when the rotation cylinder 6 is rotated, two magnetic heads 7a and 7b are not simultaneously brought into contact with the magnetic tape 17. Consequently, since only a signal given and received between either of the magnetic heads 7 and the magnetic tape 17 at the winding 12, one winding 12 can be shared by both magnetic heads and the number of the groove part for the winding can be reduced.

Filed: 1986-06-11
Abstract: PURPOSE:To permit no electric writing by preventing the potential of a gate electrode from rising when exposed to a high electric field by connecting the gate electrode with a reverse conductivity type diffused layer to semiconductor substrate provided outside a diffused region. CONSTITUTION:An aluminum electrode 1 (1)-a contact 6 between aluminum/a diffused layer-a diffused layer 7-a contact 8 between a diffused layer/a poly silicon-polysilicon gate electrode 2 are sequentially connected, and the electrode 2 is connected through the reverse conductivity type diffused layer 7 to a semi conductor substrate. A diode 13 is formed between the diffused layer/the sub strate at a gate electrode 11, and the diode 13 depends on the substrate and the impurity density of the layer 7 with a reverse breakdown strength of approx. 17-25V. Accordingly, a gate voltage below reverse breakdown strength is applied to the electrode 11 to measure characteristics. Thus, even if a strong electric field is applied during diffusing step, the rise of the gate potential is limited by the reverse breakdown strength of the diode 13. Therefore, a writing does not occur.
