Title: Polarity detecting circuit
Inventor: SEKI KANZOU
IPC: B61L19/06
Filed: 1987-04-23
Abstract: PURPOSE:To prevent the generation of a high level noise voltage by preparing a photocoupler to make ON and OFF between diagonal points of a bridge and inserting photocouplers to a side through which a positive polarity signal flows and to a side through which an inverse polarity signal flows. CONSTITUTION:When a photocoupler PC3 between diagonal points is turned ON, both detecting photocouplers PC1 and PC2 are OFF when a switch is being operated, and they are in the exclusive logical sum condition in which the outputs of the detecting photocouplers PC1 and PC2 are opposite each other when the switch is at the set position or at the inverse position. And when the photocoupler PC3 between the diagonal points is turned OFF, both the detecting photocouplers PC1 and PC2 are OFF regardless of the switching condition. Since the system is composed to detect the positive polarity current and the inverse polarity current flowing a diode bridge in which the short circuit side is composed of the photocoupler PC3 in such a way, it is not necessary to use a polarized relay, and the generation of a high level noise voltage can be prevented.

Title: Formation of bump on board for integrated circuit
Inventor: TAKAMI SHIGENARI
IPC: H01L21/60
Filed: 1990-04-14
Abstract: PURPOSE:To restrain dispersion of height of bumps at a comparatively low cost by setting the value of a current adjusting resistance to one sufficiently larger than resistance values of circuits other than the current adjusting resistance. CONSTITUTION:In the case of executing electrical plating in order to form bumps, it is essential to adjust a current adjusting resistance 4 immediately after the electrical plating is started so that a current to be applied to each substrate 2 observed by a current monitor 6 becomes equal. The current adjusting resistance 4 is provided in the same number as the substrate 2 and each current adjusting resistance 4 is set to a value which is larger by two digits or more than a resistance value (about hundreds mOMEGA) of the circuit not including the current adjusting resistance 4. Thereby, if there is dispersion in resistance of circuits not including the current adjusting resistance 4, a current density of each substrate 2 can be set to almost equal value and plating speed can be made uniform. As a result, the height of humps of each substrate 2 can be almost the same.

Title: Production of functionally gradient material
Inventor: AKASHI TAMOTSU
IPC: C04B35/71
Filed: 1993-03-31
Abstract: PURPOSE:To retain excellent characteristics of a material, minimize the residual stress and improve the efficiency, quality and reliability by using a forming outer frame as an electrically conductive passage and regulating the wall thickness thereof. CONSTITUTION:A lower pressing rod (2B) is set in a forming outer frame 2 made of a cermet material such as a metal or graphite and a raw material powder green compact 3 is filled therein. An upper pressing rod (2B) is then pushed into the forming outer frame 2 to press the raw material powder green compact under loads (2A1) and (2B1). When the melting points are (a1)<(a2) [(a1) is the melting of metal; (a2) is the melting point of ceramic], a part where the wall thickness is continuously and/or stepwise reduced from the side of the metal to the side of the ceramic is at least partially provided in the forming outer frame 2. When the melting points are (a1)>(a2), a part where the wall thickness is continuously and/or stepwise reduced from the side of the ceramic to the side of the metal is at least partially provided in the forming outer frame 2, which is used as at least one electrically conductive passage so as to form a temperature gradient in the direction of the pressurizing axis during the electrical conduction. Thereby, a pulsed DC electric current is applied across an upper electrode (2A2) and a lower electrode (2B2) to superpose discharge plasma effects on intergranular discharge effects. As a result, the green compact is sintered at a low temperature in a short time.

Title: Current lead for superconductive coil
Inventor: TOYODA KATSUYOSHI
IPC: H01F6/06
Filed: 1983-06-01
Abstract: PURPOSE:To prevent a current lead from burning without increasing a refrigerator power largely, by a method wherein gas of intermediate temperature is introduced from the refrigerator to intermediate temperature portion of a conductor, and gas amount from the intermediate portion to normal temperature portion is increased. CONSTITUTION:In a refrigerator 11, helium gas of intermediate temperature, for example, helium gas of temperature near 80K cooled by a liquid nitrogen cooler is taken out by a supply tube 15, and the helium gas is introduced to an intermediate temperature part of an inner cylinder 7 of a current lead 5 by an intermediate temperature cooling gas inlet port 14. Since burning fault is apt to occur at high temperature side rather than at low temperature side of the current lead, helium gas of intermediate temperature is introduced from the refrigerator to corresponding temperature portion of the current lead and flow amount of the cooling gas is increased at the high temperature side, thereby the burning faultis prevented. On the other hand, efficiency of the refrigerator becomes high as gas temperature exhausted from the refrigerator becomes high.
