Title: Magnetic head and its production
Inventor: UEHARA TOSHIO
IPC: G11B5/23
Filed: 1992-01-16
Abstract: PURPOSE:To prevent gap spacers from peeling and to improve hardness and wear resistance by interposing contact metals containing Cr between magnetic cores and the gap spacers. CONSTITUTION:The magnetic head 24 is constituted by housing the cores 26 wound with coils 30 into a shielding case 34 and packing an epoxy resin therein. Plural sheets of the magnetic cores 26 consisting of 'Permalloy(R)' are laminated via shielding plates 28. A magnetic gap 32 is formed at the front end of the magnetic cores 26 for sliding with a magnetic tape. The magnetic tape sliding surface side of the magnetic head 24 is provided with a tape guide 40 for guiding the tape. The gap spacers 43 consisting of SiO2 are formed in the magnetic gap 32 of the magnetic head 24 and the contact metals 44 containing Cr are interposed between one side of the gap spacers 42 and the magnetic cores 26. The metals 44 are preferably formed to >=2nm film thickness. The adhesive power of the gap spacers 42 is increased by the intervention of the metals 44. The generation of the peeling of the gap spacers 42 is obviated and the environmental resistance is improved.

Title: Charge pump circuit
Inventor: NAITO SEIGO
IPC: H03L7/08
Filed: 1986-01-16
Abstract: PURPOSE:To generate stably a voltage required for the control of a VCO from a phase comparator output pulse by taking out an output from a common collector obtained by connecting one of collectors of a pair of pnp and npn transistors(TRs). CONSTITUTION:When both the pnp and npn TRs 16, 21 are turned off, the current from a constant current source 13 flows into the earth, the current from a constant current source 22 flows into a VEE and no current flows into the TRs 16, 21 because their output impedance is high. When clocks B, C' are turned to 'H' and 'L' respectively, only the TR16 is turned on and the output potential is increased. When clocks B, C are turned to 'L' and 'H' respectively, the TR21 is turned on, the output potential is dropped and a volt age proportional to the pulse width difference between the pulses B and C is generated. Thus, the voltage required for the control of the VCO can be stably generated from the output pulse of a phase comparator.

Title: Electrode structure for touch panel
Inventor: FUJISAWA HIROAKI
IPC: G06F3/044
Filed: 1989-01-13
Abstract: PURPOSE:To increase strength in the vicinity of an electrode by forming a silver film on a transparent conductive film coated on a glass or ceramics insulating material, and further providing a bismuth alloy on the silver film. CONSTITUTION:Silver paste is applied onto the transparent conductive film (ITO) 3 of a glass base 4, followed by heating at 460 deg.C for about 30 minutes. At this stage, glass having a low melting point contained in the silver paste is stuck onto the ITO film 3, that is, the silver paste is stuck thereto, thereby forming a silver film 2. Alloy made of Bi and Sn in the ratio of 58:42 is soldered on the film 2. Since the eutectic alloy made of Bi and Sn in the ratio of 58:42 is free from volumetric shrinkage and has a low melting point, its residual distortion is small and its residual stress is low so that the stress is absorbed in the silver film 2. Therefore, strength in the vicinity of an electrode can be increased.
