Title: Forming and mounting method of solder bump
Inventor: MAEDA KEN
IPC: H05K3/34
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a method of surely forming solder bumps and mounting bumps. SOLUTION: A solder ball 15 is soldered to a circuit electrode 12 via of a through-hole 13 provided to an insulating board 11 for forming a solder bump 16 on the surface of the insulating board 11 opposite to its other surface which confronts the circuit electrode 12. In this case, the solder ball 15 is mounted on the through-hole 13 whose diameter is smaller than that of the solder ball 15, a creamy solder 14, which contains solder particles 14a that are each large enough in size to come into contact with both the surfaces of the solder ball 15 and the circuit electrode 12, is fed into the through-hole 13, the insulating board 11 is heated after the solder ball 15 is mounted on the through-hole 13 have the solder ball 15 and the solder particles 14a melted.  With this setup, the solder particles 14a function as a bridge to span a space between the solder ball 15 and the surface of the circuit electrode 12, whereby the melted solder can be prevented from separating off.

Title: Cleaning brush
Inventor: KURODA NORITAKA
IPC: G03G21/10
Filed: 1993-03-25
Abstract: PURPOSE:To maintain good cleaning performance without causing damage to the surface of an image carrier, while ensuring freedom from a drop in the service life of a cleaning brush, by forming the cross section of the fiber of the brush into a ellipse. CONSTITUTION:A cleaning brush 12 is composed of a foundation 16 flocked with brush fiber 15 and wound around a metal shaft 17. Also, the fiber of approximately elliptical form is used as the bristles of the brush 12, and the bristles are flocked, so that the major axis of the elliptical cross section of the bristle is faced to an arbitrary direction, relative to the direction of a photoreceptor drum. According to this constitution, when the fiber 15 of the cleaning brush 12 rubs the surface of an image carrier, the major axis of the fiber 15 of the brush 12 is twisted in a direction along the surface of the image carrier, due to the travel of the carrier and the rotation of the brush 12, and the brush 12 contacts the wide area of the photoreceptor, thereby allowing a large amount of toner to be removed. As a result, an effect for rubbing image carrier surface with the fiber 15 of the brush 12 can be enhanced.

Title: Speed display device for vehicle
Inventor: TAKEUCHI MIKIO
IPC: G01P1/07
Filed: 1981-05-06
Abstract: PURPOSE:To elevate accuracy of speed display of a speed display device which switches and displays a car speed at every prescribed time, by continuously executing detection of car speed data until the time point when the car speed display is switched, so that its car speed data is diaplayed when the car speed has been switched. CONSTITUTION:A pulse corresponding to a car speed obtained from a car speed sensor 1 is counted by the time decided by a counter 7. On the other hand, a clock signal whose frequency has been divided at 30 is converted to a binary number by a counter 3, is sent to a binary-10 line converter 5, and 10 line signals Q0-Q9 are outputted in order repeatedly. Subsequently, the signal Q0 is sent to a latching circuit 8 as a latch signal, and also is sent to an RSFF6 as a set signal. As a result, the RSFF6 generates an H level signal, and the counter 7 stops counting a car speed pulse. At the same time, the circuit 8 holds car speed data, simultaneously sends this car speed data to a display part 10, and executes a digital speed display. The latch signal becomes an L level as soon as the signal Q1 is generated. Also, the counter 7 is reset by the signal Q2.

Title: Femur member of artificial hip joint
Inventor: JIYAN ARAN EPINETSUTO
IPC: A61F2/36
Filed: 1986-03-27
Abstract: The femoral component of a hip prosthesis comprises a shaft, from the upper face of which projects a neck carrying a spherical head intended to seat in a cotyloid component. The shaft, which tapers toward a lower end, is curved to connect the neck to the axis of the femur, and comprises, in its upper part, two planer frontal faces, each cut by dovetail-shaped channels. Two packing pieces, an anterior packing piece and a posterior packing piece, engage these faces through bearing faces. Towards the lower part of each packing piece, a stud with a frustoconical head engages the dovetail-shaped channel to guide the packing piece during the installation of the femoral component and to permit a millimetric displacement of the core relative to the packing pieces and to the femur, in response to the variations in the verticle load on the prosthesis. The packing pieces have external convex faces. The external convex faces of the packing pieces are rough to assure connection with the spongy bone as it grows.
