Title: Lead frame for multi-chip loc package and semiconductor element package using it
Inventor: KITAHARA MIKIO
IPC: H01L23/50
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a lead frame for a multi-chip LOC package which dispenses with an expensive die for punching out a double-faced adhesive tape and copes with the complicated shapes of a semiconductor element. SOLUTION: Only the semiconductor element mounting part 1a of a lead frame for an LOC package where at least two semiconductor elements can be mounted is coated with a thermo-plastic polyimide resin 2. Thus, no expensive die for punching out a double-faced adhesive tape accurately is necessary, and the lead frame can cope with the complicated shapes. Further, a thick double-faced adhesive tape is unnecessary to be used, resulting in a thin package with no continuity failure due to punched burrs.

Abstract: PURPOSE:To obtain a highly corrosion-resistant permanent magnet and a highly corrosion- resistant bonded magnet whose acid-resistant property and corrosion-resistant property are extremely excellent by a method wherein a magnet body using a magnetic metal including iron is covered with a tannic acid-phenol-aldehyde polycondensate and this assembly is solidified by using a synthetic resin. CONSTITUTION:A magnetic metal to be used contains 50 atomic % or higher of iron; an Nd-Fe-B-based alloy or its powder as a magnetic material which can obtain a highest magnet characteristic at present is especially preferable. A resin produced by polycondensing a tannic acid, phenols and aldehydes by using an acid catalyst is used as a coating material. A so-called hydrolysis-type tannic acid or a so-called condensation-type tannic acid can be used as the tannic acid. An arbitrary mono-valent or divalent phenol such as a phenol or the like is used as the phenols. An aliphatic aldehyde or the like such as formaldehyde, acetaldehyde or the like is used properly as the aldehydes. A phenolic resin or the like can be used as a binder used to manufacture a bonded magnet. The corrosion-resistant property of the bonded magnet is much more excellent than that of ordinary bonded magnets. The corrosion- resistant property of a sintered magnet is much more excellent than the magnet which is not coated at all.

Title: Method and device for coating moving support body in curtainform
Inventor: MARUKUSU GUETSUGI
IPC: B05C5/00
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To decrease the influence of air carried by a moving support and to attain the complete stabilization of a poured curtain by evacuating the air on the collision-wetting line of the curtain and near the support immediately above a pouring roll with an evacuating device in which an evacuating opening is arranged at the front end. SOLUTION: Air carried along a support 5 is obstructed completely by the liquid film of a curtain 3 at the section of a collision-wetting line. This process causes disturbance, for example, the deformation of the curtain 3 causing the deterioration of coating quality. Although most of air carried by a blade 7 is obstructed from the wetting line, the complete prevention of the intrusion of leaking air and the formation of a boundary layer is impossible. In order to prevent the intrusion of the leaking air completely, grooves 17 are formed over the whole length of the blade 7, arranged immediately behind the front end of the blade 7, and connected to an evacuating device through a passage 18 in order to discharge the air intruded. In this way, when the curtain 3 collides with the moving support 5, the substantial stabilization of the curtain 3 can be achieved.
