Title: Precedent erasing device for rotary magnetic recording medium
Inventor: KANESHIRO TOSHIO
IPC: G11B5/024
Filed: 1986-05-07
Abstract: PURPOSE:To eliminate necessity of adjustment by making a permanent magnet piece for erasing brought into sliding contact with a rotary magnetic recording medium automatically at specified low contact pressure by the displacement driving mechanism of an erasing head. CONSTITUTION:A damper 40 makes an erasing head He in contact with a rotary magnetic recording medium D at low contact pressure when the head is brought into contact with the medium by a displacement driving mechanism DDM for bringing the erasing head He into contact with the recording medium D or separating from the medium. When current is not supplied to an exciting winding 37, the movable piece 39 made of ferromagnetic material of the displacement driving mechanism DDM is separated from a center pole 36 by elastic force of a suspension 38 made of elastic material fixed to a yoke 35, and the erasing head He is held in the state off from the rotary magnetic recording medium. When current is supplied, the movable piece 39 is magnetically attracted to the center pole 36 resisting elastic force of the suspension 38 and made to the state of sliding contact.

Title: Carriage mechanism for floppy disk device
Inventor: ISHIGAKI MASAO
IPC: F16H25/24
Filed: 1987-04-30
Abstract: PURPOSE:To ensure the stable supply of a sufficient amount of lubricating oil to a lead screw by using a plate spring member containing an oleo-flexible member to supply the lubricating oil with a contact secured with the lead screw via a member which suppresses the plate spring member toward the needle side with a contact kept with the lead screw. CONSTITUTION:When a lead screw 11 is revolving, a plate spring 20 and a flexible member 21 have contacts with the top part of the screw 11. The member 21 contains previously the lubricating oil and supplies it to the screw 11. That is, the lubricating oil contained in the member 21 oozes out by a minute amount by the frictional heat generated between the screw 11 and a needle 13. Then the oil is applied to the periphery of the screw 11. Thus the screw 11 always receives a sufficient amount of lubricating oil within a main body of a floppy disk device.

Title: Manufacture of positive electrode plate for alkaline storage battery
Inventor: HORIBA TATSUO
IPC: H01M4/26
Filed: 1990-04-20
Abstract: PURPOSE:To accomplish a high capacity/density and provide quick electrification by coating the positive electrode with an electroconductive coating layer consisting of Ni, Co, etc. CONSTITUTION:A high density Ni electrode in paste form is composed of an active substance layer electrode basis 2 and an electroconductive coating layer 3 consisting of Ni, Co, etc., wherein the surface of the Ni electrode is coated with the layer 3. The coating layer 3 shall exist either on a single side or both side of the Ni electrode surface, and the composition shall differ from the active substance layer 1. Too large thickness of the layer 3 should sink the capacity density of the electrode itself, while too thin causes unsatisfactory effect of the coating layer 3, and a thickness between 10-100mum is favorable in practical application depending upon which material is used to the electroconductive substance. This accomplishes a high capacity/density and provides quick discharging.
