Title: Lead frame material covered with al-sn eutectic film
Inventor: YASUE YOSHIHIKO
IPC: C23C30/00
Filed: 1989-12-21
Abstract: PURPOSE:To realize a low cost when an IC device is assembled and mounted by a method wherein the outermost layer of a metal-based lead frame blank is covered with an Al-Sn film layer whose thickness is 0.5mum or higher. CONSTITUTION:An Al-Sn eutectic film layer 2 is formed on one face or on both faces of a substrate 1 as a metal lead frame blank; and its thickness is set at 0.5mum or higher. In this case, solderability of the Al-Sn eutectic film formed on the surface is enhanced by Sn which is contained in a eutectic structure; and both a bonding property and the solderability can be satisfied. A masking operation is not required when Al is vapor-deposited; and it is not required to remove Al at an external lead part. Thereby, a cost can be lowered when a lead frame is manufactured.

Title: Thermal transfer printer
Inventor: KOBAYASHI TAKAO
IPC: B41J17/30
Filed: 1988-12-29
Abstract: PURPOSE:To prevent generation of new folds from being produced due to contact distance irregularities with an ink film with the elimination of folds by providing a bow-like rotating member of a structure to come in contact with the ink film on an ink film transport path. CONSTITUTION:A bow-like rotating member 8-A consists of an elastic coil member 9 and holding members 10, 11 on both ends, and is axially supported on bearings 12, 13 in a freely rotating manner. An ink film 3 is bent in the form of a curvature by the bow-like rotating members 8-A before reaching a thermal head 4. Consequently, the ink film 3 becomes increasingly rigid to eliminate folds. In addition, the ink film 3 comes in contact with the bow-like rotating member 8-A uniformly in an overall width direction because the diameter of the member 8-A is the same all along in the longitudinal direction. If the member 8-A is allowed to rotate in an opposite direction to the transport of the ink film 3, a back tension on the ink film 3 in a width direction becomes uniform and therefore, generation of new folds is prevented. At the same time, the ink film 3 is always stretched outward due to the wound state of a coil member 9.

Title: Pressure proof piping
Inventor: KAWAMOTO YOJI
IPC: F16L9/04
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To increase the breaking extension of a piping to an explosion and the like more than a thick wall piping by giving the rigidity and the strength at the same level as the thick wall piping, by winding and laminating sheets in a coil form, and pressure welding and integrating a scope of a specific length from the end. SOLUTION: Sheets 11 such as steel plates are wound in a coil form to make a laminate plate, and its starting point 12 and the ending point 13 are welded, and as to a scope 2 of a specific length from the end, a pressure welding part 21 made by pressure welding and integrating the sheets is formed. The thickness of the sheets 11 is made as the thickness to expect a plane stress condition to an even tensile load, and the length of the scope 2 is made in the scope generating a bending stress in the thickness to an inner pressure. As a result, the strength and the regidity at the same level as a thick plate which has the same thickness as the total thickness of the sheets 11 are obtained.  At the end connecting with a flange and the like, a bending moment is generated to the inner pressure, but since a laminate plate is integrated, the strength and the rigidity same as the thick plate is obtained. Furthermore, a breaking by the piping inner pressure is generated at the trunk 1, but since this part is not integrated, the breaking extension is larger compared with a thick plate, and it is hardly broken.

Title: Ultrasonic flow-velocity measuring apparatus
Inventor: OKAMURA SHIGENORI
IPC: G01P5/00
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain an ultrasonic flow-velocity measuring apparatus in which phases of reflected ultrasonic waves are put in order so as to acquire coherent received waves and whose measuring accuracy can be ensured sufficiently by a method wherein an oval-shaped measuring part is formed inside a measuring pipe and transducers are arranged and installed in both focal positions of it. SOLUTION: An oval-shaped body shell 7 is installed in a measuring part 1a inside an ultrasonic flow-velocity measuring pipe 1, and transducers 2, 3 are arranged and installed in both focal positions of it. When ultrasonic waves are transmitted from a transmitting element at the transducer 2, a part of the ultrasonic wave reaches a receiving element at the transducer 3 as rectilinear propagation waves. However, the greater part of the ultrasonic waves are reflected only once by the inside wall of the oval-shaped body shell 7 so as to reach the receiving element at the transducer 3 in the focal position on the other side in the same time. Consequently, received waves which are output from an amplifier circuit 5 are changed into coherent waves in which phases are put in order and in which the reflected ultrasonic waves are overlapped.  Then, a changeover circuit 6 is changed over, ultrasonic waves are transmitted from the transducer 3, and coherent waves are output from the circuit 5 in the same manner. Consequently, it is possible to obtain the measuring pipe 1 whose measuring accuracy can be ensured sufficiently.
