Title: Semiconductor device
Inventor: KUWABARA EIJI
IPC: H01L29/786
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To form an MOSFET of an SOI structure having a gate electrode structure in which threshold can be easily controlled and low gate resistance can be easily realized, by forming a gate electrode consisting of a laminated layer containing of a titanium nitride layer and a metal layer having a high melting point. SOLUTION: The threshold of an MOSFET is determined by the work function of a TiN constituting a TiN layer and an impurity concentration of an Si layer. Since the work function of silicon is near the center of bandgap of the silicon in both the cases of NMOSFET and PMOSFET, the thresholds can be controlled to an appropriate. In this case, if the thresholds of NMOSFET and PMOSFET are 0.3 V and -0.3 V respectively, the impurity concentration of the Si layer is approximately 1×1015 cm3, and no special channel doping is required. Accordingly, this facilitates control of the threshold of the MOSFET of an SOI structure by a gate electrode having a laminated structure, and possible to reduce the gate resistance.

Title: Method for recovering platinum from silver electrolytic slime
Inventor: KIMURA TSUGIO
IPC: C25C1/20
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To recover platinum as a platinum salt by subjecting a silver electrolytic slime to nitric acid parching, then subjecting the precipitate after filtration to hydrochloric acid parching and adding ammonium chloride to a parching liquid contg. the platinum. SOLUTION: The silver electrolytic slime is dissolved by nitric acid parching, i.e., hot concd. nitric acid and the precipitate obtd. after filtering and washing contains the greater part of the platinum in the slime. This precipitate is subjected to hydrochloric acid parching by using the hot concd. nitric acid and an ammonium chloride soln. is added to the resulted hydrochloric acid parching liquid. As a result, the platinum in the hydrochloric acid parching liquid turns to ammonium platinic chloride, which is separated and recovered as the platinum salt. The concn. of the ammonium chloride soln. is regulated to 130 to 260g/l and this soln. is added to the hydrochloric acid parching liquid at a ratio of 1/8 to 1/6.  The recovered platinum salt is subjected to a platinum purification treatment by vaporizing the ammonium chloride in a muffle, furnace, etc., to form sponge platinum and converting this sponge platinum to platinic acid chloride by aqua regia dissolution.

Filed: 1983-09-30
Abstract: PURPOSE:To perform autonomic local/remote switching by transmitting and receiving a command between the central processing units in a data communication system which has the two central processing units and a communication control processor. CONSTITUTION:When a local connection state is switched to a remote connection state, a local central processing unit 1-B generates a switching command and informs a data communication circuit and the remote central processing unit of the switching to the remote connection. It is confirmed that no data processing is being performed, and a channel route connected to the local central processing unit 1-B is disabled whereas an auxiliary storage device stored with a program for remote control is enabled. This operation allows a command to be on standby from the remote central processing unit 1-A, entering the remote connection state. The switching to the local connection state is performed similarly.

Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To make easy the accuracy control of vibration detecting positions and to provide an inexpensive vibration transfer plate and an inexpensive coordinate input device by using a piezoelectric material to form the vibration transfer plate. SOLUTION: Vibration generated by a vibrator 4 of a vibration input pen 3 is inputted to a vibration transfer plate 8 having piezoelectric property. When vibration propagated on the vibration transfer plate 8 reaches each of four electrodes 6a-6d arranged at prescribed positions of the vibration transfer plate 8, an electric signal, based on the vibration is taken out from each electrode. A signal wave form detecting circuit 9 detects the vibration reaching each electrode, based on this electric signal. An arithmetic control circuit 1 calculates the coordinates of the vibration input position, based on the reaching timing of the vibration. Since the arrangement of the electrodes 6a-6d on the vibration transfer plate 8 is realized by a technique such as etching or printing, the accuracy control of the vibration detecting positions is notably made easy.

Abstract: PROBLEM TO BE SOLVED: To obtain an AC current waveform close to a desired waveform by supplying a power output section with a power command value varying such that the impedance characteristics of a power converter, viewed from an AC power supply, suppresses a harmonic current flowing into the power converter.
