A three-piece solid golf ball of the three-layer structure comprising a solid core, an intermediate layer, and a cover is provided. When hardness is expressed by JIS-C scale hardness, the core surface hardness is higher than the core center hardness by 8-20 degrees, the intermediate layer hardness is higher than the core surface hardness, and the cover hardness is higher than the intermediate layer hardness. The ball has a weight of 41-44.5 grams. The golf ball exhibits consistent performance independent of head speeds.

A two-piece solid golf ball comprises a solid core and a cover enclosing the core and having a number of dimples in its surface. The solid core is formed of a rubber base and has a specific gravity of at least 1.00. The cover has a greater specific gravity than the core. The golf ball has an inertia moment (M) within the range given by the following expression: M.sub.DL .ltoreq.M.ltoreq.M.sub.UL wherein M.sub.UL =0.08D+84.8 and M.sub.DL =0.08D+77.8 wherein D is a Shore D hardness of the cover, the dimples occupy at least 60% of the ball surface, and V.sub.0 is in the range of 0.4 to 0.65. V.sub.0 is the ratio of the volume of the dimple space below a plane circumscribed by the dimple edge to the volume of a cylinder whose bottom is the plane and whose height is the maximum depth of the dimple measured from the bottom. The ball is improved in flight distance, controllability, roll and straight travel upon putting.

A magnetic recording medium is constructed with a substrate made of glass, one or two underlayers, and a magnetic film. In order that the easy magnetization axis of the magnetic film is parallel to the magnetic film, an underlayer having an NaCl crystallographic structure is superposed on the substrate. A magnetic film made of a Co based alloy having a hexagonal close packed crystallographic structure is formed on this underlayer, putting an underlayer made of a material having a body centered cubic crystallographic structure therebetween at need. Magnetic anisotropy of the magnetic film is increased by forming grooves in a predetermined direction in a surface portion of the substrate. These grooves play a role also for defining the orientation of the underlayer made of the material having an NaCl crystallographic structure.

There is a trend to increase that area of a device requiring a memory of large capacity, which is occupied by a semiconductor memory. This trend obstructs reduction of the size of the device. The present invention contemplates to provide a memory which can have a high integration, a high density and a large capacity while minimizing the mounting area. In order to achieve this memory, the TAB (Tape Automated Bonding) of the prior art is mounted on an electrically conductive connector, and a plurality of structures composed of the TAB and the connector are stacked. Moreover, the connector mounting the TAB thereon is constructed such that the independent terminals of the stacked TABs may not be shorted.

This invention concerns a semiconductor device of a tape carrier type and a method of manufacturing the same, wherein electroconductive layers made of the same material as that of lead terminals are disposed so as to substantially surround the circumferential edge of a hole for containing an IC chip with a predetermined gap as barrier portions for controlling the flowing range or the coating range on a carrier tape before coagulation of the coating material when the surface of said IC chip after being inserted into the IC chip-containing hole and connected with the lead terminals is coated with the coating material. The steps formed with the surface of the carrier tape and the barrier portions which substantially surround the circumferential edge of the hole at a predetermined gap thereby results in controlling the flowing range of the coating material before coagulation, by which the coating region on the surface of the IC chip, etc. with the coating material is made uniform and the scattering in the film thickness is minimized.
