Title: Process for reducing corner recess formed in shallow trench isolation
Inventor: JANG SYUN-MING
IPC: H01L21/76
Filed: 1998-12-31
Granted: 2000-07-01
Abstract: This is an improved process for reducing corner recess formed in shallow trench isolation. A porous O3-TEOS oxide layer is deposited to take over traditional known PE-SiH4 oxide layer formed by PECVD process. It is used as a mask layer to define self-aligned salicide zone. The porous O3-TEOS oxide layer has a property of higher etching rate. It can be removed by etching. Thus, the shallow trench isolation will not be damaged to form corner recess in order to prevent accumulating etching residue and forming junction leakage current. If an etching agent, which has concentration higher than that of conventional agents, is applied, then its relative effectiveness will be highly raised. The porous O3-TEOX oxide layer can be made by reducing depositing pressure or temperature, or by controlling supplying ratio of raw material O3: TEOS.

Title: Driving power transmission mechanism for disk device
Inventor: SAKURAI TOSHIHIRO
IPC: G11B17/051
Filed: 1999-02-20
Granted: 2003-08-21
Abstract: A disk device body becomes complicated when different powers are used to drive a disk carry-in means and a disk discharge means. A transmission gear 37 is constituted by mutually combining the fitting part 37A1 of an upper gear 37A and the fitting part 37B1 of a lower gear 37B and both are freely movable in an axial direction. Thus, even in the case that a ceiling plate 2 provided with the carry-in means A of a disk and a clamp chassis 3 provided with a clamp mechanism K, etc., are vertically moved, prescribed driving power is surely transmitted to a large gear (first gear) 36 and a rotary cam (second gear) 7. Thus, the carry-in means and discharge means of the disk are driven by one simple driving power transmission mechanism. Also, since the carry-in operation and discharge operation of the disk are performed at the same time, the required for changing the disk is shortened.

Title: Measuring method for monitoring the PPID effect
Inventor: WANG MU-JIUN
IPC: H01L21/66
Filed: 1999-06-22
Granted: 2001-03-21
Abstract: There is provided a measuring method for monitoring the PPID effect, which comprises: providing a chip having a plurality of dies; measuring the initial gate current of each die without antenna effect; measuring the gate threshold current of each die with antenna effect; comparing the gate threshold currents of each die with and without antenna effect to find the difference. When the gate threshold current of any die with antenna effect has a magnitude order larger than a predetermined magnitude order, or when the difference in magnitude order between the gate threshold currents of the die with and without antenna effect is smaller than a predetermined magnitude order, it indicates that the die can not work normally due to problem in reliability or being out of functions. The present invention can effectively determine the dies that are out of functions due to the antenna effect.

Filed: 1999-10-04
Granted: 2001-09-01
Abstract: The present invention discloses a CD-ROM driver (2) having a safety circuit (40). Safety circuit (40) has a NOR gate (51). One of the input terminals of NOR gate (51) is connected with the signal terminal (48) of driving and controlling compact disc rotation for the system controller (31). The other input terminal of NOR gate (51) is connected with the output terminal (P1) of sensor (13). System controller (31) outputs a low level signal when driving motor (18), and outputs a high level signal when making motor (18) stop. Motor (18) will rotate when the output of NOR gate (51) is at high level, and will stop when the output is at low level. When output of sensor (13) is at high level, it is irrelevant to the output of system controller (31), and output of NOR gate (51) becomes low level so as to make motor (18) stop.

Title: Method and apparatus for reliable data communications
Inventor: JOHANSSON MATHIAS
IPC: H04W84/12
Filed: 1999-12-07
Granted: 2002-02-11
Abstract: A data communications unit determines both efficiently and accurately when one or more data units should be received under a variety of conditions. In particular, the present invention compensates for transmission delays and for varying transmission rates over the communications channel. During a communication between first and second communications nodes, the first node receives a sequence of data units transmitted from the second node. The first communications node determines that one or more of the transmitted data units was either not received at all or was erroneously received (i.e., corrupted). The first node then sends a request to the second node to retransmit the one or more data units not received or erroneously received. A retransmit timer is started when the retransmission request is sent. The retransmit timer accounts for the delay time period required for the retransmit request to reach the second node, for the second node to retransmitted the requested data units, and for the retransmitted data units to reach the first node. When the timer indicates that the delay time period has occurred/expired, a counter is started. Based on the counter's value, a determination is made whether all of the data units requested to be retransmitted have been properly received. If the determination indicates that the requested one or more data units has been retransmitted and properly received, no further action is taken. On the other hand, if the requested one or more data units to be retransmitted is not received or is erroneously received, the above-described procedure is repeated.

Inventor: ORIGUCHI TOSHIKI
IPC: C08F18/08
Filed: 2000-02-16
Granted: 2005-05-21
Abstract: A process of the invention produces a vinyl acetate polymer based emulsion by seed polymerization of vinyl acetate in an ethylene-vinyl acetate copolymer based emulsion. This process includes a step of performing seed polymerization while adding vinyl acetate to a system, and, prior to or subsequent to the step, a step of adding a polymerizable unsaturated monomer other than vinyl acetate to the system. The amount of the polymerizable unsaturated monomer other than vinyl acetate is, for example, about 0.05 to 10 parts by weight relative to 100 parts by weight of vinyl acetate. At least one monomer selected from acrylic esters, methacrylic esters, vinyl esters, and vinyl ethers can be used as the polymerizable unsaturated monomer other than vinyl acetate. The invented process can produce a vinyl acetate polymer based emulsion which has satisfactory low-temperature film-forming property and adhesive strength, even containing no plasticizer, and which can exhibit a high adhesive strength even when cured at low temperatures.
