Abstract: PURPOSE: To prevent glass drop-out caused by the bumping of glass at the glass fusing by making the glass material inserted in the inside between the butt faces of a pair of magnetic head core blocks at a temperature higher than the ambient temperature by the use of auxiliary heating sources.  
     CONSTITUTION: A magnetic head core block piece 4 which has coil winding grooves 2 and has been inserted with a glass rod 7 in its glass rod inserting groove and a magnetic head core block piece 6 which has a recess 5 for the notched part for defining the effective track width of the magnetic head are butted together by way of a spacer not illustrated. These are samdwiched by th auxiliary heating sources 11A, 12A composed of sandwiching blocks 8A, 9A such as transparent quartz and good thermal conductive metals of a circular cone having the bottom of the diameter R larger than their width S and are thereby pressed from above and below and are heated with a heating source 10.

Title: Die cast sleeve
Inventor: FUKANO KATSUTOSHI
IPC: B22D17/20
Filed: 1989-02-10
Abstract: PURPOSE:To avert the galling of a molten metal by specifically forming three layers into an integral structure, dividing the 2nd layer to a plurality in the axial direction, superposing the divided layers on each other in the form of a socket and spigot type and grooving the superposed parts to form clearances in the axial direction. CONSTITUTION:The coefft. of thermal expansion of the metal of the 2nd layer 1b is larger than the coefft. of thermal expansion of the ceramics of the 1st layer 1a and the metal of the 3rd layer 1c and, therefore, even if the molten metal of a high-temp. is injected into the die cast sleeve 1, the generation of a clearance 1x by the difference in the thermal expansion between the 2nd layer and the 1st layer 1a on the 3rd layer 1c is suppressed. The 2nd layer 1b having the largest thermal expansion during hot is divided to a plurality in the axial direction and since the divided layers are so arranged as to form the clearances 1x in the axial direction, there are the margins for the deformation in the axial direction and the deformation by the thermal stress in the axial direction is prevented. In addition, the 2nd layers 1b have the parts where the layers are superposed on each other and the superposed parts are grooved. The layers can, therefore, be smoothly and integrally deformed in the axial direction at the time of the high-temp. expansion. The 1st layer 1a and the 2nd layer 1b adhere tightly to each other at the high-temp. time of molten metal injection and the deformation, such as camber and bend, of the ceramics of the 1st layer 1a is obviated.

Title: Measuring method of bulk density of coal
Inventor: OGURI KATSUHIKO
IPC: G01N9/00
Filed: 1985-02-18
Abstract: PURPOSE:To calculate bulk density simply with precision close to the actual furnace condition by charging a coal sample into a cylindrical sample vessel and compressing it with a piston in the vessel and measuring the relation between the applied pressure and the bulk density. CONSTITUTION:The coal sample of the quantity more than the volume of the sample vessel 2 is charged into the vessel 2 and the excessive sample of the upper surface of the vessel 2 is cut and the weight of the sample is weighed. This vessel 2 packed with the sample is loaded on a load cell 1 and the relation between the dropping distance of the piston 3 and the applied pressure is recorded with a recorder 5 by lowering the piston 3 at the specified speed. Since the packed volume of the sample is obtained from the dropping distance, the bulk density is calculated from the calculated sample weight in advance. Consequently, the bulk density for the applied pressure corresponding to the impressed force of the actual furnace is calculated immediately.

Title: Magnetic disk device
Inventor: UCHIKURA HIDEAKI
IPC: G11B5/31
Filed: 1982-02-26
Abstract: PURPOSE:To improve the margin of signal discriminating operation by using thin-film magnetic heads which differ in magnetic pole thickness at a circumference side of a recording/reproduction radius and at an outer circumferential side. CONSTITUTION:Magnetic heads 55 and 56 at the outer circumferential side have greater magnetic pole thickness than magnetic heads 53 and 54 at the inner circumferential side. The frequency characteristics of the outer circumferential magnetic heads have peeking reduced by making the magnetic pole thickness greater than that of the inner circumferential magnetic heads, thereby decreasing undershoots. Consequently, the margin of discriminating operation when reproduced signals of the magnetic heads are discriminated by amplitude is improved.
