Title: Semiconductor device and method and device for manufacturing the same
Inventor: AOKI EIICHIRO
IPC: H01L31/02
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To establish a technology for manufacturing a semiconductor device by which the manufacturing process of a semiconductor device can be easily simplified and automated and the material cost of the device can be reduced and, at the same time, the investment can be reduced, by eliminating the need of large-scale production facilities by sealing a synthetic resin base member by sticking a light transmissive cap to the member. SOLUTION: An ultraviolet-curing sealing agent is applied to a specific portion of a base section 3 formed by molding a thermosetting synthetic resin, and the section 3 is sealed by putting a light transmissive cap 8 made of a synthetic resin or glass on the section 3 and curing the sealing agent by irradiating the agent with ultraviolet rays. A lead frame 1 formed by integrally molding a plurality of base sections 3 is supplied to every wafer from a loader 20, and a dispenser applies the ultraviolet- curing sealing agent to the upper peripheral surface of a cavity section 4. Then a cap placing device places the light transmissive cap 8 on the cavity section 4 and the wafer is carried to a UV irradiation equipment. The equipment cures the sealing agent by projecting ultraviolet rays upon the agent.  Consequently, the cap 8 is stuck to the upper peripheral surface of the cavity section 4 and the section 4 is sealed.

Title: Recovering method and device of metal from solution
Inventor: DARTNELL NICOLAS JOHN
IPC: C25C1/20
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To maintain a high current density without causing undesirable side reaction by correcting the plating voltage and/or plating current according to changes in the voltage difference between the cathode and anode at different two current levels caused by changes in the metal concn. in the soln. SOLUTION: The difference in the voltage when an electrolytic cell 2 is operated at different two current levels is monitored by repeatedly measuring with a probe in a short time at a second level while plating is performed at a first current level. By changing the plating current when the voltage difference reaches to the max., for example, silver can be rapidly recovered with high current efficiency. A controlling unit 28 is preliminarily adjusted to correspond to the peak in the curve relating to the silver concn. and to the voltage difference in order to control the current applied on the electrolytic cell 2 to a higher or lower level, or to turn on and off the switch in the plating process when the recovering process of silver is to be started and completed.

Title: Control method for vertical transport device
Inventor: SAKAMOTO KEIICHI
IPC: B65G54/02
Filed: 1991-07-11
Abstract: PURPOSE:To make truck stop positions accurate by accelerating trucks by means of the propelling power sum of two linear motors at the time of start, moving two trucks by means of the thrust of a linear motor alone that is opposite to one side truck, before stop. CONSTITUTION:A drive control portion gives brake power that consists of the reverse direction thrust sum of two linear motors, to trucks 3a, 3b. As a result, trucks 3a, 3b, in comparison with a case in which one side linear motor alone is operated, are decelerated to the lowest speed at a shorter deceleration section. Next, the drive control portion, at the time point when trucks 3a, 3b have reached predetermined stop positions, stops the operation of one side linear motor that has been kept operating at a section before stop. As a result, there is no drive power to trucks 3a, 3b, and trucks 5a, 5b stop at stop positions. When the movement of vertical transport device I trucks is controlled as above, trucks 3a, 3b can be moved to stop positions in a short time, and also stopped at accurate positions.

Title: Offset correction circuit of digital-analog converter
Inventor: CUKIER MAURICE
IPC: H04B14/06
Filed: 1988-08-12
Abstract: PURPOSE: To evade the offset of an analog output by correcting the offset at the time of correcting PLO so that a clock for controlling the input of a digital word to a sigma/delta converter is slowed down or speeded up. CONSTITUTION: A state A is held until the slow-down operation SD or speed-up operation SU of the PLO is executed. When the speed-up operation SU is executed, the system is changed from the state A to a state B at a succeeding crystal oscillator pulse. Then the system is advanced to a state C or a state D in accordance with a result that a sigma/delta bit is a '1' bit or a '0' bit. When the polarity of sigma/delta data is changed, the state is immediately changed from C to E (or D to E). The state E expresses that the generation of a correction pulse is possible. Then the system is returned to the state A waiting for new PLO correction. When the PLO slow-down operation SD is executed, the system directly changed from the state A to the state E for generating a correction pulse.

Title: Sintered body of high thermal shock-resistance
Inventor: KOMABAYASHI MASASHI
IPC: H01L35/32
Filed: 1993-07-20
Abstract: PURPOSE:To obtain a high thermal shock-resistant sintered body high in resistance to a thermal shock caused by a quick change in temperature by a method wherein a surface layer is so provided as to protect an inner layer which is prescribed in mechanical strength at high temperatures against cracking caused by a thermal shock. CONSTITUTION:An inner layer 1 is possessed of a prescribed mechanical strength at high temperatures of 800 deg.C or so. Two surface layers 2 are so formed as to vertically sandwich the inner layer 1 in between them to protect the inner layer 1 against cracking caused by a thermal shock. That is, even if cracks are generated in the surface layers 2 due to a thermal shock caused by a quick temperature change from 800 deg.C to tens of  deg.C by cooling with water or water vapor, the cracks are prevented from propagating by the layer 2 so as not to reach to the inner lawyer 1. Therefore, an FeSi2 sintered body is not wholly damaged. Therefore, the FeSi2 sintered body is enhanced in resistance to a thermal shock caused by a quick change in temperature and hardly lessened in internal electrical resistance.
