Title: Device for detecting material to be conveyed
Inventor: YANATORI HIROMI
IPC: B65H7/02
Filed: 1985-09-20
Abstract: PURPOSE:To surely detect the rear or front end of a sheet with no affection upon the sheet, by providing a pressure-sensitive element for detecting varaitions in pressure, corresponding to the thicknesses of materials to be conveyed. CONSTITUTION:When a sheet X is held between conveying rollers 1A, 1B which are rotated, the conveying roller 1B which has been made into slight contact with the conveying roller A is slightly displaced along an elongated hole 3 to apply a pressure onto the outer surface of a pressure sensitive element 5 due to the insertion of the sheet X. Accordingly, the output voltage of the pressure sensitive element 5 varies when the sheet X is clamped between the conveying rollers 1A, 1B, and therefore, the leading end of the sheet X may be detected by monitoring the output voltage of the pressure sensitive element 5. Further, when the trailing end of the sheet X comes out from the conveying rollers 1A, 1B, the output voltage of the pressure sensitive element 5 varies, thereby it is possible to detect the passage of the trailing end of the sheet X.

Title: Lead frame and semiconductor package using the same
Inventor: MATSUO MITSUYASU
IPC: H01L23/50
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To provide the form of a lead frame which prevents burrs from sticking to the part from the central part to the vicinity of tip of an outer lead which burrs are generated in the resin sealing process of a semiconductor package. SOLUTION: A recessed burr stopper 10a having a depth of 1-50 μm is formed on the mold outer shape side of an outer lead 5 surface except a tie bar 4. The burr stopper 10a stores sealing resin which leaks from a slight gap between a lead frame and a sealing metal mold 7, thereby stopping burrs 9 in the vicinity of the mold outer shape. It is prevented that the burr 9 sticks to the part from the vicinity of the central part to the vicinity of a tip of the outer lead which participates the bonding when a resin sealed semiconductor package is manufactured and then mounted on a printed board. As a result, solder plating of tin or tin-lead is enabled without a burr eliminating process, and reduction of the manufacturing cost and improvement of productivity are realized.

Title: Television casting system
Inventor: OGURA SHOSEI
IPC: H04N7/00
Filed: 1985-09-24
Abstract: PURPOSE:To associate an NTSC system television with an additional information signal and easily transmit the new additional information signal by angle- modulating and transmitting a telecasting video carrier of the NTSC system with the aid of the additional information signal. CONSTITUTION:The output of an angle modulator 2 is modulated by the additional information signal 3 and generates an upper and a lower sideband wave. If the telecasting video carrier is left intact, it is slope-detected by a Nyquist slope in an image receiver and develops amplitude variation by the additional information signal. Said variation cannot be separated from original amplitude variation by a video signal because the video signal of the NTSC system is transmitted through the use of amplitude modulation. To ensure the compatibility, a characteristic compensating part is provided. This characteristic compensating part uses a filter having the reverse of Nyquist slope characteristic, and is provided given the reverse characteristic with respect to the amplitude variation generated in the receiver by the output of the angle modulator 2. This system extinguishes the amplitude variation of the video carrier by the additional information signal and removes interference as a general transmission system including a transmitter side.

IPC: C22B59/00
Filed: 1991-07-26
Abstract: PURPOSE:To remove a Ni coating film safely and easily at low cost when a waste material having a Ni coating produced from the production process of Ni-coated rare earth alloy is to be reused. CONSTITUTION:The rare earth alloy having a Ni coating film is hydrogenated into a powder, which consists of particles having Ni films, particles having no Ni film and Ni particles. Since the hydrogenated rare earth alloy has no ferromagnecity, particles having Ni films and Ni particles can be attracted by a magnet when magnetic force is applied to this powder, while particles having no Ni film remain. Thereby, the rare earth alloy containing no Ni is separated and reused as at least one part of the source alloy for the production of the rare earth alloy.

Abstract: PURPOSE:To obtain the title compsn. having an excellent flame retardance and well-balanced properties and showing a stable melt viscosity during molding by compounding polybutylene terephthalate with a brominated epoxy flame retardant and an antimony auxiliary flame retardant. CONSTITUTION:The title compsn. comprises polybutylene terephthalate and/or a copolymer contg. at least 60wt.% butylene terephthalate units, 2.0-25.0wt.% (based on the compsn.) brominated epoxy flame retardant, 2.0-15.0wt.% (based on the compsn.) antimony auxiliary flame retardant. and 0-70wt.% (based on the compsn.) inorg. filler. Although the use of the flame retardant alone prevents the viscosity increase and gelation of the compsn., the moldability and mechanical properties become inferior; the use of the auxiliary flame retardant alone gives the compsn. poor in melt stability, mechanical properties, and moldability. The combined use of these two ingredients exhibits a synergistic effect, giving the compsn. having well-balanced properties.
