Title: Manufacture of permanent magnet of rare earth-iron system
Inventor: MIZOGUCHI TETSUHIKO
IPC: H01F1/057
Filed: 1986-07-11
Abstract: PURPOSE:To obtain a high-performance permanent magnet by producing crystalline thin bands of a permanent magnet alloy of the rare earth-iron system, and then stacking, heating and integrating them, or grinding them and kneading them in a binder for molding. CONSTITUTION:An alloy represented by the formula I is used (where R is Y and at least one of the rare earth elements; M is one or more combination containing Ga of Ga, A, Ti; and B, Fe, Co are contained with the atomic ratios alpha-delta of equation II). If Nd and Pr are contained in R to 70% or more and a part of B is substituted by C, N or the like to about 80%, high BHmax is obtained. This molten alloy is jetted onto a cooling body rotating at a predetermined speed. The obtained crystalline thin bands are stacked and integrated at 600-1100 deg.C, 0.1-2 tons/cm<2>. Alternately, the alloy ingot is made into powder of 5-30mum (0<beta<=0.95). After receiving surface treatment for anti-oxidizing and improvement of bond properties with resin, it is kneaded with 10wt.% thermoelastic resin 6 and injection molded. With this arrangement, a permanent magnet of high magnetic flux density, coercive force and Curie point and large energy product is obtained.

Filed: 1987-06-29
Abstract: PURPOSE:To prolong the lifetime of a battery, by providing a switch circuit controlling the ON-OFF operations of a head power source element which supplies a voltage to a head of a printer in linkage to a cover switch detecting the opening and closing of a protective cover of the printer. CONSTITUTION:When an ignition switch 10 is made, a voltage V1 of a battery 9 is supplied to each element through a system power source 11. With the running of a vehicle, a signal from a sensor element 1 is counted by a processing circuit element 2 and renewed serially in a prescribed clock period to be data on the running, and the data are displayed 3 and also stored 4 together with data from a time counting element 8. Pairing the running data inputted in each prescribed clock period with the time count data, a storage element 4 stores them while shifting them sequentially, thus holding constantly the data inputted in a certain prescribed time. When a driver comes to a place whereat he desires to collect informations, in the course of running of the vehicle, and pushes a lock switch 6, the processing circuit element 2 stops transfer of the data to the storage element 4, and the data inputted within the prescribed time are held in the storage element 4 after the lock switch 6 is operated. When a printing switch 15 is turned ON, it turns possible to print the data by a printer 12.

Title: Antenna system
Inventor: EBINE YOSHIO
IPC: H01Q9/32
Filed: 1986-07-11
Abstract: PURPOSE:To obtain a multi-frequency resonance and a non-directional antenna within the horizontal plane by fitting parallel parasitic antenna components to one sleeve antenna. CONSTITUTION:The length of exciting elements 10, 10' of the sleeve antenna is nearly 1/2 wavelength and the parasitic antenna elements 4 are fitted near the exciting element of the sleeve antenna. Let the length of the exciting element be L, the distance between the exciting element and the parasitic antenna element be DELTAS, the length of the parasitic antenna element be l, the thickness of the parasitic parasitic element be rho, and l/L be smaller than 1, then the 2nd frequency is resonated, which is higher than the 1st frequency. Nondirectivity is attained in th horizontal directivity in the 1st frequency f0 if the thickness rho is sufficiently thinner than the wavelength. The two parasitic antenna element 4 are arranged around the sleeve antenna symmetrically with the same DELTAS in order to make the horizontal plane directivity in the 2nd frequency non-directional. Thus, the horizontal planer directivity in the 2nd frequency 1.69f0 is made non-directional.

IPC: H01J29/28
Filed: 1985-07-22
Abstract: PURPOSE:To inhibit the thermal expansion of a shadow mask by increasing its ability to absorb heat without preventing the permeation of electron beams by forming heat-absorbing films over the areas of a metal back surface other than those corresponding to phosphors in a fluorescent screen. CONSTITUTION:The heat-absorbing films 7 of a color picture tube are formed on a shadow-mask-side layer formed on a metal back surface 5. After the formation of the metal back surface 5, a liquid suspension prepared by dispersing an aqueous PVA (polyvinyl alcohol) solution nd ammonium dichromate in a quick drying solvent principally composed of an alcohol such as methanol or ethanol is applied to the metal back surface 5 and then the entire surface is exposed to light to form a water-insoluble primer layer. Next, polyvinyl alcohol and a dichromate-system photosensitive resin are applied to the primer layer to form a layer. After that, the thus formed layer is exposed to red, green and blue colors prior to development and then application of graphite and removal of the photosensitized films are performed, thereby forming the heat- absorbing films 7.
