Title: Magnetic head
Inventor: KANEKO KENJI
IPC: G11B5/127
Filed: 1988-04-26
Abstract: PURPOSE:To fix the joining area of back cores with common cores so as to regularize the magnetic efficiency by shifting the front end sections of two back bars facing each other from each other and, at the same time, joining the two back bars by means of a nonmagnetic bar so that the end faces of the front end sections of the two back bars can be positioned in the same plane. CONSTITUTION:A back core 9 is constituted of a back bar 9a magnetically joining a recording and reproducing core 1 and common core 2 with each other, back bar 9b magnetically joining an erase core 4 and common core 5 with each other, and nonmagnetic bars 9c and 9d. The back bars 9a and 9b are joined with each other in such a way that the front end sections of the bars 9a and 9b on the sides facing each other can be shifted from each other and the end faces of the front end sections can be positioned in the same plane and a nonmagnetic body 7 is fitted so that the body 7 can overlap the back bars 9a and 9b. When such constitution is adopted, a magnetic head which is stable in magnetic efficiency and good in yield can be produced, because the joining area of the back cores 9 with the common cores 2 and 5 is fixed even if a slight fitting error is produced.

Abstract: PURPOSE:To enable an accelerated member to be accelerated at a high speed by a method wherein an electric current is applied in a closed circuit formed by a rail and an electric conductor to generate an electromagnetic acceleration force and at the same time a gas generated from the electric conductor is injected from a nozzle to accelerate the accelerated member. CONSTITUTION:A high electric current 1 flows in a closed circuit formed by a rail 1 and an electric conductor 5 to generate an electromagnetic acceleration force F in an advancing direction (x) and then an electric conductor 5 is evaporated by a high electric current, regulating in that a gas of plasma evaporation substance is produced. This generated gas is injected by a nozzle 13 under an ultra-sonic speed rearwardly with respect to a propulsion direction to generate a propulsion force. Although an amount of an electric conductor 5 is gradually diminished due to evaporation, an electrical energization is carried out through plasma generated at the part of the electric conductor 5, resulting in that the electromagnetic acceleration force is generated until the plasma is diminished. As described above, in addition of the electromagnetic acceleration force F, the propulsion force caused by the injection of the gasified gas is made to accelerate the accelerated member 2, so that the accelerated member 2 can be accelerated at a higher speed.

Abstract: PURPOSE:To obtain a smooth surface of a magnetic layer which causes no deformation of a tape nor clogging of a magnetic head by polishing the magnetic layer with an abrasive tape before curing and before the calendering process removing a low mol.wt. component which is not cured and sufficiently removing a binder layer on the surface of the magnetic layer. CONSTITUTION:The magnetic layer is formed by coating a nonmagnetic supporting body with a magnetic coating material comprising a ferromagnetic powder dispersed in a binder, and drying. A tape containing an abrasive powder of 0.1 - 0.5mum average particle size is made to slide on the magnetic layer to polish its surface in the opposite direction to the traveling direction of the magnetic recording medium having the magnetic layer. Then the magnetic layer is subjected to supercalendering and then cured. This treatment is performed so that the spectrum obtained by X-ray photoelectron spectroscopy of the surface of the magnetic layer shows the integral intensity ratio of Cl-2P line to Fe-2P(3/2) line ranging from 0.35/1 to 0.46/1. Thereby, deformation of a magnetic tape and clogging of a magnetic head can be prevented and the obtd. magnetic layer has a smooth surface.

Filed: 1990-04-18
Abstract: PURPOSE:To improve the utilization efficiency of a bus by permitting the transmission of a data packet from each terminal with the terminal itself at the time when a carrier wave is not present on a transmission medium for a prescribed time. CONSTITUTION:One of terminals 11 to 1n transmits a data packet (a) by CSMA/ CD(carrier sense multiple access/collision detection) 4.

Abstract: PURPOSE:To operate the circuit of a light receiving element or a light emitting element sufficiently by positioning a synthetic-resin insulating layer among a photo-connector made of a metal, a receptacle and the light receiving element or the light emitting element. CONSTITUTION:The receptacle 1 of the photo-connector made of the metal, which consists of the receptacle 1 and a plug 2, and the light receiving element 4 are bonded while positioning the synthetic-resin insulating annular body 5 between the receptacle and the light receiving element. A section between the receptacle 1 and the element 4 may be insulated electrically by using an insulating paint layer in place of the annular body 5. When employing the photo- connector made of the metal, the function of the light receiving element or the light emitting element is frequently damaged remarkably on the operation of the circuits of these elements when the sheath section of the light receiving element or the light emitting element is made of the metal and the contactor pin of the P-N junction of these elements and a metallic sheath section are common. Accordingly, the circuits of these elements can be operated sufficiently by electrically insulating the photo-connector and these elements.

Filed: 1985-05-17
Abstract: PURPOSE:To shorten the time to start boiler by measuring and comparing with a set temperature the temperature of the steam generated at the outlet of a boiler and the environmental temperature for the heat transfer faces in a boiler and calculating the position of the primary burner from the deviation in the comparison and using a primary burner that matches the calculated position. CONSTITUTION:The temperature 8 of the steam generated at the boiler outlet and the temperature 7 of the gas around the heat transfer faces in the boiler are measured and those measured temperatures are compared with set temperatures corresponding to those temperatures. From the deviation in the comparison the most suitable burner ignition position among primary burners 2 is calculated. On the basis of this calculated position, ignition instruction which issues an order to extinguish burners that are ignited at present and an order of ignition to a most suitable position is given to a burner ignition and extinguishing device. Since with this system a most suitable ignition position and fuel charging amount can be determined with respect to the variation in heat absorption in the boiler furnace and it is also possible to increase the amount of fuel that can be charged with protection to the heat transfer faces, shortening of boiler starting time can be effected.
