Granted: 2001-01-21
Abstract: The invention discloses a method for forming gate oxide layers with different thickness of flash memory. Protect the edge of a shallow trench isolation (STI) oxide layer in the low voltage device area to avoid etching by using the inter-gate dielectric layer of flash memory as a hard mask. First, provide a substrate divided into memory cell area, peripheral low voltage and high voltage device areas by an STI oxide layer. Then, form a tunnel oxide layer, deposit and pattern the first poly silicon layer and deposit inter-gate dielectric layer at the memory cell area. Remove part of the inter-gate dielectric layer and use it as a hard mask to form a thick gate oxide in the high voltage device area. Remove more inter-gate dielectric layer and form a thin gate oxide in the low voltage device area. Then, deposit the second poly silicon layer and proceed a photo-lithography etching on the memory cell area. Finally, proceed photo-lithography etching on the peripheral circuit gate.

Title: Disc discriminating method
Inventor: MASUDA EIJI
IPC: G11B7/126
Filed: 1999-04-14
Granted: 2001-03-21
Abstract: This invention is directed to a method for preventing a short wavelength laser from damaging the data recorded in CD-R discs when laser rays with different wavelengths are used to regenerate and record discs having different densities. In the method, a laser beam with a long wavelength is incident on a disc while the disc is not rotating in order to determine whether or not the disc is a CD-R disc. If not, a short wavelength laser beam is incident on the disc to determine if it is a DVD disc. By using an actuator (9), a converging lens (10) is moved in the direction of the axis of the incident beam, and an amplitude value of a focus error signal or a total light signal AS obtained thereby is used to discriminate discs.

Title: Dental floss device and dental floss used by the same
Inventor: SHEN CHUNG-SHAN
IPC: A61C15/04
Filed: 1999-09-15
Granted: 2001-07-11
Abstract: The present invention relates to a dental floss device and a dental floss used by the same. The device comprises a handle, a limit sleeve, a positioning cover, and a hook holding seat; in which an elastic hook head installed on the upper end of the handle is used for the limit sleeve to buckle thereon, the positioning cover then covers on the limit sleeve so that the positioning cover and the limit sleeve are formed into an integral body. The inside of a through hole in the positioning cover is installed with a groove for housing a screw part of the hook holding seat therein. The protrusion rib of the screw part matches the groove on the inside of the through hole so that the hook holding seat is restricted to move forward and backward linearly. The external thread installed on the lower end of the screw part meshes with the internal thread of the elastic hook head. By rotating the handle, the hook holding seat can move forward or backward. The dental floss forms a knot on the two ends of the thread, respectively. After the dental floss is hooked on the hook holding seat on the positioning cover and the hook thread rod of the hook holding seat, a rotation on the handle can tighten the dental floss for use. A rotation in the reverse direction can loosen the dental floss for dismounting the dental floss.

Title: Automatic gain control circuit
Inventor: DUMAS JEROME
IPC: H03G3/20
Filed: 1999-09-16
Granted: 2001-06-16
Abstract: An automatic gain control, AGC, circuit comprising with a preferred transition region. A gain correction unit is responsive to an attenuate command and amplify command coming from a feedback system monitoring the AGC's output. The feedback system can individually adjust the delays of both attenuate and amplify commands sent to the gain correction unit. Additionally, the present AGC also includes a transition region detector that monitors the input signal applied to the AGC to from a feedforward system. The transition region detector producing a control output to selectively permit the gain correction unit to respond to an attenuate or amplify command. If the magnitude of the input signal is greater than a predetermined value, then it will place a disable signal on its control output to prevent the gain correction unit from altering its gain. However, if the magnitude of the input signal remains greater than the predetermined value for a long time, then a timer will override the transition region detector and enable the gain correction unit to adjust its gain.

Title: Q9 Pin-yin Chinese character input method and keyboard thereof
Inventor: LEUNG LAP-YAN
IPC: G06F40/00
Filed: 1999-12-22
Granted: 2003-06-01
Abstract: The present invention is a Q9 Pin-yin Chinese character input method applied on telecommunication and computer products, especially small or miniature type products, and a corresponding keyboard thereof. It divides input of Chinese character into three steps, including consonant, single vowel, and compound vowel. Only three keys are required to be pressed before character selection. Since the tone of the Chinese character is input at the same time when inputting the compound vowel, the number of characters to be selected in character selection is reduced significantly and, therefore, the input time is shortened. Also, a Q9 keyboard is applied to make the input method particularly ideal for mobile phone applications, such as on-line connection and e-mail transmission. The input method of the present invention is simple and direct perceivable and requires no learning by rote. Those who are familiar with Chinese Pin-yin may learn it in three minutes.

Title: Stacking block game
Inventor: HOLAHAN EDWARD THOMAS
IPC: A63F9/00
Filed: 2000-01-28
Granted: 2003-01-01
Abstract: A stacking block game includes a plurality of game blocks stackable in layers, and an elongate sleeve comprising four planar sides defining an interior for retaining the game blocks in layers in the interior. Apertures are provided in the sides, coincide with the game block layers and are dimensioned for passing the game blocks therethrough. The game blocks have a cuboid shape and colored indicia on the faces thereof, and are inserted in the sleeve interior in layers of four game blocks. The stacking block game is played by assigning a different indicia to each player, and then each player ejecting one of the game blocks from the sleeve interior, in turn, by pressing a previously-ejected game block through one of the apertures and against a game block opposite the game block to be ejected. Generally, each player makes a note of the indicia on the uppermost face of the previously ejected game block, and then presses that game block against the indicia of a game block in the sleeve matching the noted indicia. However, if the indicia on the uppermost face of the game block ejected on a player's turn matches that player's assigned indicia, the player repeats the turn and is entitled to press the ejected game block against any of the game blocks in the sleeve. The players take turns ejecting game blocks until all of the coloured indicia adjacent one of the sides match one of the player's assigned indicia.
