Title: Welding tip
Inventor: KAKEHASHI HIROYUKI
IPC: B23K9/26
Filed: 1985-05-02
Abstract: PURPOSE:To prevent the falling of the tip end with the heating by an arc during the welding work by fitting the end tip with pressure in the state of fastening to the engaging hole of the main body of the tip. CONSTITUTION:An end tip 2 is formed in the cylindrical shape having a flange 11 at one part and the thickness t1 of the cylindrical part is taken as less than the thickness t2 of the engaging hole 5. The guide hole 12 provided on the shaft center is formed in the same diameter as that of a inserting hole 3 and the flange surface 10 is finished in a mirror face. The outer diameter of the end tip 2 is formed so that the fastening allowance for the inner diameter of the engaging hole 5 becomes in about zero. The end tip 2 is fitted in the state of coinciding the guide hole 12 with an inserting hole 3 to the engaging hole 5 of the tip main body 1 with the fastening-fit by pressure. The fastening allowance is thus set more than the gap caused by the difference in the thermal expansion rates of the tip main body and end tip and the chattering and falling of the end tip is prevented.

Title: Magnetic disk and its production
Inventor: KURATOMI ISAO
IPC: G11B5/84
Filed: 1992-04-16
Abstract: PURPOSE:To improve the durability and glide height characteristic of the magnetic disk and a magnetic head by setting the intersection angles of fine grooves at a fixed angle and distributing the intersection points uniformly on the surface of a substrate. CONSTITUTION:A magnetic disk substrate 1 rotates in an arrow C direction and a polishing tape 2 is pressurized by a polishing roller 3 in the inner peripheral part of the substrate 1. With this part as a start point, the tape 2 is moved at a constant speed in the arrow D direction of the substrate 1 toward the outer peripheral part of the substrate 1, by which polishing is executed. The rotation of the substrate 1 is stopped and both the tape 2 and the roller 3 are returned to the start point of the polishing state when the tape 2 parts from the substrate 1. The rotating direction of the substrate 1 is then inverted to an arrow E direction and the second polishing stage is executed under the same conditions. The substrate is cleaned and dried when the fine grooves 4 are formed on the surface of the substrate 1 by alternately repeating the first and second stages plural times. A Cr film, Co alloy film and carbon film are then successively formed by a sputtering method and thereafter, a lubricant is applied on the surface. The lubricant is thereby uniformly dispersed and the durability of the magnetic disk and the magnetic head is improved.

Title: Constant-voltage power supply unit and its starting-up method
Inventor: MORIMOTO KENJUN
IPC: G05F1/56
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To shorten the delay time from the application of an input voltage to the rise of an output voltage by inserting a transistor which is previously activated before the input voltage is applied between an input and an output terminal. SOLUTION: An operational amplifier OP1 is supplied with a source voltage Vc before being applied with the input voltage Vin, so the transistor Q3 is always ready to operate. Therefore, the output voltage Vo is outputted through the transistor Q3 right after the input voltage Vin is applied. At this time, the output voltage Vo is fed back to the inverted input terminal of the operational amplifier OP1 through the transistor Q3 even if a transistor Q1 is turned off, so that the output voltage Vo is kept constant. When a transistor Q2 and the transistor Q1 begin to supply a current to a load with delay respectively, the current supply from the transistor Q3 is cut off and switched automatically to the current supply by the transistor Q1.
