Title: Semiconductor device using complementary clock and signal input state detection circuit used for the same
Inventor: TAGUSHI MASAO
IPC: H03K5/135
Filed: 1997-09-25
Granted: 1999-08-21
Abstract: A semiconductor device for generating first and second internal clocks complementary with each other from an external clock and usable for both a system of a type using a complementary clock and a system of a type generating a 180 degree phase clock internally, is disclosed. A first clock input circuit (buffer) is supplied with a first external clock and outputs a first internal clock. A second clock input circuit (buffer) is supplied with a second external clock complementary with the first external clock and outputs a second clock. A 1/2 phase clock generating circuit generates a 1/2 phase shift signal 180 degree out of phase with the first internal clock. A second external clock state detection circuit judges whether the second external clock is input to the second clock input buffer. A switch is operated to produce the second clock as the second internal clock is input and to produce the 1/2 phase shift signal as the second internal clock when the second external clock is not input, in accordance with the judgement at the second external clock state detection circuit.

Title: Method and system for limiting current in a read/write head retract circuit
Inventor: JEFFREY EDWARD N
IPC: G11B5/54
Filed: 1997-10-09
Granted: 1999-08-21
Abstract: A method and system for limiting current in a read/write head retract circuit is disclosed. The system includes a temperature sensor for sensing a temperature of the disk drive read/write head retract circuit. The temperature sensor generates an output signal indicating whether the temperature is above or below a threshold temperature. The system also includes a voltage regulator which applies a voltage to an actuator motor. The voltage regulator receives an input signal operatively associated with the output signal of the temperature sensor, and adjusts the voltage applied to the actuator motor in response to the input signal. In one embodiment, the system includes a hysteresis circuit which adjusts the threshold temperature of the temperature sensor when the temperature sensor output changes. The hysteresis circuit prevents the system from oscillating rapidly around the threshold temperature of the temperature sensor, and thereby avoids unnecessary wear of the system components.

Title: Protection of a metal by vulcanizing liquid ebonite
Inventor: RAPPOPORT LEONID
IPC: C08G59/58
Filed: 1997-11-18
Granted: 2001-06-16
Abstract: A mixture comprising epoxidized liquid rubbers, amine hardeners and sulfur applied to a metal and cured produces a coating that is highly durable and provides strong anticorrosive protection to the metal. The amine hardeners [16] serve to activate and dissolve the sulfur, speed up the curing time, and also to link the rubbers [10] to each other, creating a continuous molecular matrix [22]. The activated sulfur [12, 20] also links the rubber molecules together, as well as anchoring the polymer matrix [22] to the metal substrate [18] via chemical bonds. In a preferred embodiment, the formulation also includes two types of accelerators which act synergistically to further reduce the curing time to less than one hour. The addition of micronized aluminum oxides provides increased uniformity of heating during curing and results in a more uniform coating. The addition of calcium oxide together with the presence of amines and aluminum oxide provides a complete absorption of acidic gases produced during curing. The addition of high molecular butadiene nitrile rubber increases the coatings impact resistance, low-temperature flexibility, and adhesion.

Title: Continuous time filter with programmable bandwidth and tuning loop
Inventor: PIERSON RICHARD C
IPC: H03H11/04
Filed: 1998-08-04
Granted: 2000-01-11
Abstract: A transconductor is provided having a transconductance Gm. This transcondcutance is then attenuated with a steering circuit (41) to attenuate the overall transconductance of the transconductor and vary the bandwidth. A fixed voltage is then input to the transconductor with the output thereof offset with a programmable current DAC (48). This output is then provided to an error amplifier (46) for developing an error voltage. This error voltage is then input back to the input of the transconductor to adjust the transconductance thereof to minimize this error. The steering circuit (41) is controlled by a voltage DAC (58) to program the attenuation provided thereby. Both the voltage DAC (58) and the current DAC (48) are controlled by a bandwidth control signal to program the bandwith of the overall transconductor. This is facilitated while compensating for the process and temperature variations of the transconductance of the transconductor. This is also facilitated with a master/slave relationship.

Abstract: The present invention relates to a key switch of which the object is to enhance the freedom of indication printing on a key top and ensure the switching operation of a contact. The solution of the present invention is that an LED 5 is mounted on a lower base 1 with a central fixed contact 6 and a peripheral fixed contact 7. An upper sheet consisting of a light diffusive material is laminated on the lower base 1 and integrated thereto. A top part of a momentary spring 2 functioning as a movable contact is adhered to the lower surface of the upper sheet 3, so that the peripheral part of the momentary spring 2 is regularly brought into contact with the peripheral fixed contact 7, and its top part is separated from the central fixed contact 6 with a predetermined distance. The projection 8 is formed by printing on the upper surface of the upper sheet 3, and the position of the projection 8 is made coincident with the top part of the momentary spring 2. A display part is formed by printing on the flat bottom surface of a key top 4 formed of a transparent material, and the pressing force is transmitted to the top part of the momentary spring 2 through the projection 8 and the upper sheet 3 when the top surface of the key top 4 is pressed, thereby making contact with the central fixed contact 6.

Title: Method of increasing etching selectivity with Si-rich SiON layer
Inventor: FU JU-YUN
IPC: H01L21/768
Filed: 1998-07-24
Granted: 2000-06-01
Abstract: In a self-aligned dual damascene interconnect production process, an effective protection can not be furnished due to insufficient etching selectivity between the SiON layer, used as the etch-stop layer, and the silicon oxide dielectric layer. While an increase in the thickness of the SiON layer can improve the situation, this will cause an increase in the parasitic capacitance. In an ordinary self-aligned contact (SAC) process for a memory device , usually a silicon nitride layer is used as the etch-stop which needs to be etched off subsequently to expose the substrate. During such an operation, since the cap of the gate and the spacer are also silicon nitride layers, there is no etching selectivity among them, thereby causing a loss on the thickness of the two and affecting the isolation properties. Therefore, the present invention discloses an improved process, which increases the flowrate of SiH4 in the feed gas and reduces the flowrate of N2O to deposit a Si-rich SiON layer to be used separately as the etch-stop in a self-aligned dual damascene interconnect process and a cap of gate and spacer in a SAC process, thereby increasing the etching selectivity between itself and the silicon oxide layer or the silicon nitride layer and effectively obviating the drawbacks existed in the conventional techniques.

Title: Communication Services system and its position registration method
Inventor: SU SHU-JIN
IPC: G06F15/173
Filed: 1998-10-09
Granted: 2000-06-21
Abstract: The communication services system contains multiple registration regions to manage the upper HLR database in the registration area. Each registration region is mapped to a VLR (Visitor Location Record Unit) database. To a user, multiple registration regions are divided into several regions so that a region can be composed of one or many registration area (s). A VLR database is assigned as a region server (RS) in each region. VLR database transfers the registration message to the previous registering region server (RS) when the users finish sending the registration message. If entering a new region, the cross-region registration is just in process, which means the registration is proceeded in HLR.
