Patent TW-280001-B (TW)
Title: Multiple-function GaAs transistors
Inventor: SHEU WEY-JOU
IPC: H01L21/205
Filed: 1995-07-04
Granted: 1996-07-01
Abstract: Four new four-terminal single and multiple delta-doped transistors with multiple functions grown by low-pressure metalorganic chemical vapor deposition (LP-MOCVD) have been fabricated successfully. All the epilayers are grown on n+-GaAs substrates. The real-space transfer transistors (RST's), by making the collector under the substrate, reveal very strong negative differential resistance phenomena. The RST structure using an InGaAs channel manifests superior characteristics of a very high peak-to-valley current ratio up to 430,000 at room temperature, a peak current as high as 100 mA, very sharp charge injection, and a valley current as broad as 5.5 V. Meanwhile, high performance heterostructure field effect transistors can be implemented on the same wafer by further evaporating a gate between source and drain electrodes. To significantly reduce leakage current, an ohmic recession is made at the source and drain. These new multi-function devices may be used in high-speed, low-noise, and/or high power microwave oscillator and amplifier.

Title: Address translation device
Inventor: NOGAMI KAZUTAKA
IPC: G06F12/10
Filed: 1995-10-28
Granted: 2000-06-21
Abstract: The address translation device of the present invention utilizes TLB circuit with a plurality of ways to perform address translation, such that the processing speed can be secured without reducing the hit ratio of the address translation, and the access to the TLB circuit is minimized to save the power consumption. The address translation device includes a virtual page number register (4), a physical page number register (5), and a TLB (translation look-aside buffer) circuit (1). A virtual page number register (4) stores a last-accessed virtual page number. A physical page number register (5) stores a physical page number corresponding to the virtual page number stored in the virtual page number register (4). TLB (translation look-aside buffer) circuit (1) stores multiple relationships between the physical page number and the virtual page number. First, a comparator (6) compares a new virtual page number (2) with the virtual page number register (4)'s output. If the new virtual page number matches the output of the virtual page number register (4), the output of the physical page number register (5) is produced through a multiplexer (9) as a physical page number (3). If the new and stored page numbers do not match, a comparator (6)'s mismatch signal (7) activates the TLB circuit (1) so the TLB circuit (1) output is produced through a multiplexer (9) as a physical page number (3).

Abstract: An internal clock signal generator in which a delay locked loop (DLL) or a phase locked loop (PLL) is connected to a synchronized delay circuit. The DLL or the PLL is connected to a synchronized delay circuit such as synchronous delay line (SDL). The synchronized delay circuit generates a clock signal which is coarsely locked to an external clock signal, and the DLL or the PLL generates an internal clock which is much finely locked with the external clock signal by receiving the clock signal output from the synchronized delay circuit. Therefore, the locking time of the internal clock signal with respect to the external clock signal is shortened and the degree of accuracy in the locking range becomes high.

Title: Underground continuous wall construction method of excavate-subside stack double wall type
Inventor: SHIU CHI
IPC: E02D5/20
Filed: 1998-12-18
Granted: 2000-02-11
Abstract: The invention provides an excavate-subside stack double wall method to construct the underground continuous wall. There are the working steps: (1) Install guide grooves and guide walls at the predetermined location. (2) Allocate the first continuous wall unit, double pre-fabricated, at the bottom layer between the guide walls. (3) Proceed the drilling grooves process after Install the driller: use driller equipped with water injector and dipping pump to work and let the lower wall unit subsided downward followed by the reducing groove volume. (4) Stack the upper wall unit of continuous wall section upon the lower wall unit from the bottom layer. (5) Install driller again to drill grooves. Return to the step (3) and employ driller to proceed drilling so that the upper wall unit can be further subsided downward. As several wall units have stacked up to predetermined depth, grout concrete from the top to complete the first working section of continuous wall. (6) Back to the step (2) and start another unit operation until the continuous walls are completed connected. In the weak or sandy loose soil structure, as starting grilling grooves or grouting, it probably collapses and increases the working difficulty. This construction method for continuous walls can effectively solve the problem to have better quality of finished continuous walls and waterproof function. Not only could reduce the consumption of labors and working period, but also could increase the constructing efficiency, lower the noise, vibration and air pollution, and won't pollute the underground water and water and sewage conduit. Because it is constructed with compound method, better waterproof function could be enhanced.
