Title: Preparation of metal particle from molten metal
Inventor: GEORUKU RAIFU
IPC: B22F9/08
Filed: 1991-11-12
Abstract: PURPOSE: To produce fine metallic particles without occurrence of solidification or clogging in a discharging nozzle. CONSTITUTION: Molten metal is discharged from the discharging nozzle 10 to form a metallic jet stream 12. In an atomizing region 22 on the downstream side of the discharging nozzle 10, a fluid 20 is directed toward the metallic jet stream 12' and is operated by a nozzle device, and the metal is atomized to form particles. The metallic jet stream 12 is passed through an electromagnetic field (H) between the discharging nozzle 10 and the atomizing region 22 and a cross section of the metallic jet stream 12 is changed. In particular, an extremely fine spectrum of particles can be obtained by reducing the cross section.

Title: Ringback tone transmission system for private exchange
Inventor: NAGATA KEIZO
IPC: H04M3/02
Filed: 1990-11-26
Abstract: PURPOSE:To reduce the impossibility of terminating a call although the call can be terminated by holding a call request on the call originating side for prescribed time without immediately returning a busy tone to the call originating side even when the load of a ringback tone generating circuit exceeds the output capacity of the ringback tone generating circuit.

Title: Cutting and molding apparatus of semiconductor device
Inventor: NEMOTO KATSUMI
IPC: B21D28/00
Filed: 1990-11-27
Abstract: PURPOSE:To eliminate an influence by a foreign body which has adhered and to prevent a pellet crack from being caused by installing a foreign-body detection means which detects the foreign body which has adhered to a package for a semiconductor device. CONSTITUTION:A knockout 5 and a die 7 are provided with recessed shapes which correspond to the shape of a package for a semiconductor device 1; a load cell 9 as a foreign-body detection means is arranged and installed on the bottom face of the knockout 5. When an upper metal mold 4 approaches a lower metal mold 6 and the load cell 9 is brought into pressure-contact with the surface of the package for the semiconductor device 1, a pressure at this time is detected. When a foreign body 3 has adhered to the surface of the semiconductor device 1, a detected pressure value becomes large as compared with a case where it has not adhered. Consequently, a driving mechanism for the upper metal mold 4 is controlled on the basis of this abnormal detection in such a way that the lowering operation of the upper metal mold 4 is stoppedimmediately. As a result, it is possible to prevent that the pressure which is larger than it is exerted on the package. Thereby, it is possible to prevent a crack from being caused when the pressing pressure is concentrated on the foreign body.

Title: Current detecting circuit for semiconductor element
Inventor: HORII HIDESATO
IPC: H02M1/00
Filed: 1988-12-26
Abstract: PURPOSE:To improve detecting accuracy by providing the subject circuit with a voltage source for generating voltage equal to the voltage drop of a current detecting resistor and superposing voltage generated from the voltage source to a control signal for at least one of a main semiconductor element and a sub-semiconductor element at the prescribed polarity. CONSTITUTION:The voltage drop of a resistor 31 is detected and the detected voltage is converted into a signal by a signal conversion circuit 10 to form a voltage in a floating voltage state. The voltage is impressed to a voltage source 12 or 13 to form an equivalent voltage and the voltage is inserted into a signal line to the gate of a MOSFET 1 or 2 in series. Consequently, the real voltage between the gate and source of the current controlling main element 1 can be made equal to that of the current detecting subelement 2 and the linearity of a source current ratio between these elements 1, 2 can be improved. Thus, the influence of the voltage drop due to the current detecting resistor 31 can be canceled, the lowering of detecting accuracy can be suppressed and high accuracy can be obtained.
