Title: Manufacture of lead frame
Inventor: MURAKAMI KAZUYA
IPC: H01L23/50
Filed: 1987-11-30
Abstract: PURPOSE:To reduce cost, and to improve reliability by forming the pattern of a lead frame, in which a tie bar is widened up to a section near the end of an inner lead, plating the nose section of the inner lead with a noble metal and molding the tie bar up to specified width. CONSTITUTION:A lead frame is formed to a shape having a wide tie bar 13' so that an edge DL on the die pad 11 side of the die bar 13' is brought nearer to the die pad side than a noble-metal plating line ML in an inner lead 12. A support bar is bent, the surface of a die pad is molded in height lower than the nose surface of the inner lead while the edge of the die pad side of the tie bar is cut off, and the tie bar is depress-worked by using a mold shaping the tie bar 13 so that it has a normal width. The side face S of the inner lead near a package line PL in not plated with silver and maintained, thus preventing the generation, etc., of migration due to the intrusion of moisture, then improving reliability.

Title: Method for adjusting position sensor
Inventor: SETO HIDEKAZU
IPC: G01D5/36
Filed: 1986-12-19
Abstract: PURPOSE:To eliminate a speed detection error and the phase shift between outputs, by obtaining triangular wave-shaped outputs different in a phase from each other by the relative movement of a scale and a sensor and adjusting the amplitudes of the outputs so as to bring differential values to predetermined values. CONSTITUTION:Triangular wave-shaped outputs SA-SD are obtained by the relative movement of a scale having a predetermined structure and a sensor. The differential wave forms of said outputs are visually observed and adjusted in amplitude using a variable resistor so that the differential values in the vicinity of detection points XA-XD exceeding predetermined voltage upwardly to the right become prescribed values. A first, when each output is matched with output SA1 made obtuse in a wave- form in the vicinity of the max. value and the min. value, the differential wave-form DSA1 thereof becomes a square wave having large amplitude dl. Amplitude d2 is adjusted to the amplitude d1 of an ideal triangular wave and all of the outputs SA-SD are processed in the same manner. By this constitution, even when the output S is distorted, the moving speed error in the vicinity of the detection point X can be removed. When SA supposed to originally possess phase difference of 90 deg. is shifted from SB1, the wavelength of SB1 is raised as a whole to correct the phase difference of detection points XA, XB2 to 90 deg..

Title: Magnetic recording medium and cleaning tape
Inventor: KAMEI TAKAHIRO
IPC: G11B5/708
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent deposition of a burnt matter on a magnetic head even with longer sliding time and higher scanning speed, to suppress the spacing loss and to prevent increase in the error rate by incorporating a preventing agent against burning which contains an aromatic nitroso compd. into a magnetic recording medium. SOLUTION: This medium is produced by forming a magnetic layer on a nonmagnetic base body and the medium contains a preventing agent against burning which contains an aromatic nitro compd. selected from compds. expressed by the formula I, formula II and formula III. In the formulae, R<1> to R<17> are alkyl groups, aryl groups or heteroaromatic groups with substituents of hydrogen atoms, halogen atoms, hydroxyl groups, nitro groups, carboxyl groups, etc. This aromatic nitroso compd. has an ability to form a complex with metal atoms so that the complexing reaction is caused between the metal oxide on the magnetic head surface and the polyacid compd. The obtd. complex easily drops from the magnetic head surface. Thereby, metal oxides can be removed from a magnetic head, which prevents accumulation or deposition of a burnt matter on a magnetic head.
