摘要： PURPOSE:To enable the generation of a reference point signal with 1 pulse per cycle by providing magnetizing section for pusle generation on a rotor while a sensor employing a magnetic resistance element is used. CONSTITUTION:A magnetizing section 5 for reference point is provided with a range equivalent to 1-3 cycles of an increment signal in addition to an increment signal track 3. Then, each time a magnetic drum 1 rotates at one cycle, a magnetic sensor fixed facing the section 5 gains the reference point output with the pulse width equivalent to 1-3 cycles of the incrementat signal. The magnetic sensor employs magneto-resistance elements Ra1 and Ra2 arranged vertical to the movement of a drum 1, the main section extended parallel to the movement of the drum 1 and magneto-resistance elements Rb1 and Rb2 arranged close to them on the same plane with the short joint connecting them.

摘要： PURPOSE:To obtain a magnetic recordng medium of high reliability fit for use at high temp. such as a magnetic disk for a magnetic encoder by forming a magnetic layer contg. a dispersed mexture of iron oxide powder with magnetic metallic powder on a nonmagnetic substrate. CONSTITUTION:A magnetic coating liq. prepd. by kneading pure iron-base metallic powder with iron oxide powder such as Co-gamma-Fe2O3 powder is coated on a disk substrate 1 of Al or the like by a spinner method, and it is dried and baked to form a magnetic film 2. A heat resistant epoxy resin binder is used as a binder resin for the magnetic coating liq. By adding the iron oxide powder, the deterioration of the magnetic film 2 due to oxidation is prevented even at 150- 200 deg.C high temp., so a magnetic disk maintaining its high reliability in an atmosphere at high temp. and humidity is obtd.

摘要： PURPOSE:To increase a pitch between electrodes by arranging an insulating plate material whose area is greater than that of a substrate on the top surface of the substrate. CONSTITUTION:A photoelectric converting element consists of a substrate 3 wherein an optical fiber bundle 4 photodetecting and transmitting a reflected-light signal obtained by reading a transmitted original 2, an insulating plate material 10 arranged opposite the optical fiber bundle output end formation surface of the substrate 3 at a prescribed-distance interval, and a photoelectric converting film 8 sandwiched on the surface of the plate material 10 opposing to the said optical fiber bundle output end and between a common electrode 9 and many nether electrodes 6 connecting with a conductor electrodes 7. Then, wide areas are formed across the photoconductive converting film 8, so the array pitch of the conductor electrodes 7 is increased, thereby eliminating the breaking of the conductor electrodes 7 and a short circuit between the electrodes.

摘要： PURPOSE:To improve the yield ratio by connecting at least two blocking diodes in series with a photodiode to form a photosensor element, thereby automatically remedying a defective bit. CONSTITUTION:A blocking diode 3' which has substantially equal characteristics to a blocking diode 3 is connected in the same polarity in series between a photodiode 2 and the diode 3, and a 1-bit photosensor element 4' is composed in combination of the diodes 3, 3' and the diode 2. Thus, when a film defect occurs in any of the diodes 3, 3', the remaining one is normal. Accordingly, the charge which is injected from the diode 2 can be blocked by the normal blocking diode, thereby readily remedying the production of a defective bit caused by the defect of the film.

摘要： PURPOSE:To make temp. compensation easy and high temp. operation possible by using ferromagnetic material reluctance effect elements for reluctance effect elements, and making the direction of the magnetic poles of the magnet that applies magnetic bias coincident with the tangential direction of a gear. CONSTITUTION:A recess 4a is provided on the side of a permanent magnet 4 facing each tooth 2a, and a non-magnetic material substrate 6 deposited and formed with ferromagnetic material reluctance effect elements 7 on the side facing said teeth is fitted and disposed in said recess 4a. Since the tangential direction A of the gear 2 and the direction B of the magnetic bias by the magnet 4 are made roughly coincident, the bias magnetic field is applied roughly in the same direction as the tangential direction of the gear 2, and since the directions of the electric currents flowing to the elements 7 are in the intersecting directions, the change in the magnetic fields between the respective teeth 2a is largely sensed by the elements 7 in accordance with the presence or absence of the teeth 2a.
