Title: Production of hollow electroforming products by noble metal
Inventor: YASUI AKIMIZU
IPC: C25D1/02
Filed: 1995-02-14
Abstract: PURPOSE: To obtain hollow electroforming articles exactly meeting a master pattern by forming a metallic electroforming layer which melts in a mineral acid on the outside of this master pattern and removing the master pattern, then dividing this electroforming layer to a plurality, providing the inner sides thereof with noble metal electroforming layers, then melting the electroforming layers and joining the noble metal electroforming layer pieces. CONSTITUTION: The electroforming layer of the molten metal, such as copper, is formed on the outside of the master pattern molded of a low melting material. The master pattern of the internal low melting material is then heated and melted and the molten material is withdrawn outside from a hole previously formed in the copper electroforming layer. The remaining hollow electroforming layer is divided to a plurality and a coating material for masking is applied on the outer side of the divided electroforming pieces and is baked. The respective divided pieces are immersed into an electroforming liquid of noble metal, such as pure gold, by which the electroforming layers of the noble metal are formed on the copper electroforming piece sides.  The coating material for masking is then peeled and the electroforming pieces are immersed into the liquid of the heated mineral acid, by which the copper electroforming pieces are melted. The remaining electroforming pieces of the noble metal are joined by brazing, etc., in compliance with the master pattern. As a result, the precise noble metal hollow products which faithfully have the patterns of the master pattern and have the same size as the size of the master pattern are obtd.

Title: System for setting subscriber line housing information
Inventor: NARA TAKASHI
IPC: H04Q3/60
Filed: 1987-03-03
Abstract: PURPOSE:To simplify the setting of a bit of subscriber line housing information and to prevent erroneous setting from being generated, by deciding the housing of a subscriber by a master station side device by setting the bit of subscriber line housing information on a remote side equipment and transmitting the bit of subscriber line housing information to the master station side equipment via a multiplex transmission line. CONSTITUTION:A subscriber line housing information setting means 400 sets the subscriber line housing information representing the housing position of the subscriber 3 on the remote side equipment 100. A transfer means 500 transmits the subscriber line housing information set by the subscriber line housing information setting means 400 to the master station side equipment 300 via the multiplex transmission line 200. The master station side equipment 300 decides the housing of the subscriber 3 separated by the master station side equipment 300 on an exchange 1 based on the subscriber line housing information transmitted from the remote side device 100. In such a way, by setting the subscriber line housing information in the remote side device 100, the need of the setting of the information independently at the master station side equipment 300 is eliminated and labor to set the subscriber line housing information is reduced.

Title: Voltage current converting circuit
Inventor: KAMIMURA TAKUZOU
IPC: H03F3/343
Filed: 1984-03-14
Abstract: PURPOSE:To adjust the changing rate of a current value by placing a differential amplifier comprising a couple of transistors (TR) and making the emitter area ratio of the TRs different from each other. CONSTITUTION:IA is current flowing to a constant current source 6 and I1 is a current flowing to a TR2. The current at V1=VB is changed freely without change of the relation I1=IA at V1>>VB by changing the emitter area ratio of the TRs 2, 4. FIg. shows a change in the current I1 against a voltage V1-VB of a voltage current conversion circuit. That is, since the current I1 with V1-VB= 0 is given as I1={1/(1+a)}IA, the conversion rate {1/(1+a)} of the currnt I1 is changed by adjusting the emitter area ratio (a). The characteristic B is a case with increased (a) against the characteristic A and the characteristic C is a case with decrease (a). Thus, the rate of change of an output current is adjusted by adjusting the emitter ara ratio of the TRs 2, 4 in constituting a semiconductor integrated circuit in this way.
