Title: Reset circuit for flip-flop
Inventor: SASAKI KOU
IPC: H03K3/037
Filed: 1998-11-09
Granted: 2001-05-28
Abstract: The purpose of this invention is to prevent the value of a flip-flop from being indefinite during the period from the initiation to the time when the clock signal is inputted after the power is supplied. To accomplish the purpose stated above, the method used is described in the following. At the power-on time, reset circuit 21 for a flip-flop is configured to supply the clock signal to the clock signal input terminal of flip-flops 7 to 9 such that an output of each flip-flop can remain definite. For example, in the case that the input/output of tri-state buffers connected to the bus are controlled to perform at the output of the flip-flops, the generation of passing-through current caused by the indefinite output value on the bus can be prevented with a relatively small scale of circuit.

IPC: H01L21/3065
Filed: 1998-12-11
Granted: 2001-08-21
Abstract: A high density plasma etch method is disclosed, wherein the intensity of ultraviolet light is reduced to reduce the generation of bubble from nitrogen gas into the upper photoresist layer in the etching process, and to remove or reduce the thickness of the barrier layer so that Nitrogen gas can be released smoothly to avoid pressure burst. Said goal can be accomplished by changing the process parameters. The generation of Nitrogen gas in the etching process can be effectively inhibited by using said method, so this method can prevent bubbles in the unexposed region of the photoresist layer.

Title: Flash memory skeleton and operation
Inventor: LAI JEN-SHING
IPC: G06F12/00
Filed: 1998-12-14
Granted: 2002-10-21
Abstract: Flash memory skeleton and operation are provided. It improves the shortcoming of large part erasing while re-writing the flash memory, which establishes indices when re-writing and uses small fraction copy to replace large part erasing as possible. That is, when the re-writing is initiated, the re-writing content and old allocated block content are merged to write into the new allocated block and the indices are refreshed to point to the new allocated block at the same time. The new block then replaces the old one. So the accidents such as power cut, tool down and flash memory exchange will not result in large data loss and the system robustness is enhanced.

Title: A wavelength selective modulator
Inventor: AUGUSTSSON TORSTEN
IPC: G02B6/34
Filed: 1999-04-16
Granted: 2000-10-11
Abstract: The present invention relates to a device and to a method for modulating optical wavelength channels. The optical wavelength channels are switched to at least one access waveguide arranged on a first side of a first multimode waveguide (10), The wavelength channels are then transmitted through the multimode waveguide (10) and imaged on at least two connecting waveguides provided on an opposite side. The optical wavelength channels are then transmitted through the connecting waveguides. For each wavelength selective cross-switch structure (2, 4, 6, 8), the phase of a reflected wavelength is changed by two phase control elements (C1, C2, D1, D2, E1, E2, F1, F2) arranged in a first and a second connecting waveguide on a first side of said wavelength selective cross-switch structure (2, 4, 6, 8) over a given time period and slightly time shifted in relation to the second phase control element, at the same time as the phase of the reflecting wavelength remains relatively unchanged on a second side of said wavelength selective cross-switch structure (2, 4, 6, 8). For each wavelength selective cross-switch structure (2, 4, 6, 8), the phase of transmitting wavelengths is changed once in a first and a second direction per wavelength selective cross-switch structure (2, 4, 6, 8). The phase relationship between the optical signal in respective access waveguides arranged on the first side of the second multimode waveguide (20) determines where the optical signal will be focused on the opposite side.
