Abstract: A wireless group paging method allows a wireless paging control center to send specific paging message to the paging receiving device of specific group and only allows the specific paging group to effectively receive the paging message without letting other paging group receive the paging message. The characteristics of the wireless group paging method are that employs a paging group setup code to set up all paging groups under each set of paging receiving device and adds a designated code of paging group to the paging message used to only allow specific paging group to receive the paging message. The wireless group paging method can allows each paging receiving device to randomly increase and decrease the supervising paging group number and to supervise multiple paging groups without limit. Furthermore, it can allow wireless paging control center to transmit paging message only once, making all paging receiving devices of the designated paging group synchronously all receive the paging message.

Abstract: A reflective optical self-compensated LCD structure includes a substrate having a common electrode layer, a substrate having a pixel electrode layer, a polarization sheet, a serial compensation film, and a uniform liquid crystal layer, wherein one electrode layer is a transparent electrode layer and the other one is a reflective device. By injecting light through the polarization sheet, a line polarized light is formed for further passing through the compensation film and liquid crystal to form an approximated circular polarized light, which is then reflected by a mirror face and passes through the compensation film and liquid crystal to form an approximated line polarized light vertical with this polarization sheet. After applying the driving voltage, the included angle between the liquid crystal and polarization sheet is not zero. Its optical principle is to utilize an approximated circular polarized light mode. With the dual reflective feature of liquid crystal layer and suitable angle combinations, a self-compensation is performed to reduce the light leakage of full band dark status of visible light. This liquid crystal display structure can be driven at low voltage and has the features of high contrast and wide angle of view, so that the liquid crystal with Deltan of 0.075 to 0.13 still has good reliability, and the polarization converting efficiency is more than 95%.

Title: Starter circuit
Inventor: OKUYAMA YOSHIAKI
IPC: H03K17/22
Filed: 2002-05-02
Granted: 2003-12-01
Abstract: A voltage generating unit includes first resistors and a first transistor connected in series between first and second power supply lines. Since the gate of the first transistor is constantly supplied with a voltage higher than its drain voltage, the rise of a first voltage of a first node is gentle compared to that in the conventional art. A starter signal generating unit generates, according to the first voltage, a second voltage at a second node connecting a second resistor with a second transistor. The timing of reversing the logic level of the second voltage is delayed compared to that in the conventional art. Therefore, the time period from power-up until output of a starter signal is longer than in the conventional art. Consequently, even when the power supply voltage is low, the time period required to initialize an internal circuit is ensured, thereby initializing the internal circuit without fail.

IPC: F16F15/02
Filed: 2002-10-28
Granted: 2005-05-11
Abstract: This invention relates to a quake-absorbing device and installation method therefore. A conventional quake-absorbing device has been known as described, for example, in Japanese patent application public disclosure No. 2000-14472 (A). This conventional quake-absorbing device comprises an upper base secured on a subject body to be protected from an earthquake or other vibrations, a lower base on a floor, upper and lower upcurved rails attached to the upper and lower bases, and rollers which moves along the upper and the lower rails by rolling. The upper and lower rails are vertically opposed to each other across the rollers at the angle of approximately 90 degrees sp as to be arranged in the plane form of a substantially square. However, in a case where computer-associated equipment such as a computer server is protected form seismic waves, wiring such as communication and electric circuits is often laid on a floor and connected to the equipment. The wire or cable possibly comes into contact with the quake absorbing performance of the quake-absorbing device. Thus, it has been very difficult to apply the quake-absorbing device to the equipment having the wiring connected thereto. To remedy the disadvantage suffered from the conventional quake-absorbing device, the present invention provides a quake-absorbing device having improved quake-absorbing performance and a method capable of installing the quake-absorbing device without suspending the operation of existing equipment to be protected. The quake-absorbing device of the invention is distinctively provided with an opening or pass-through port for permitting the wiring connected to the equipment to pass therethrough so as not to bring the wiring into contact with the quake-absorbing device, thereby to achieve high quake-absorbing performance.

Abstract: A method of controlling the capacitance of the TFT-LCD storage capacitor is provided. The gate dielectric layer of the TFT is composed of silicon nitride layer/dielectric layer/silicon nitride layer, and the etching selectivity of the amorphous silicon layer over the dielectric layer is high. Therefore, the dielectric layer can be an etching stop layer when a doped and an undoped amorphous silicon layers are etched to form source/drain stack layers or a conductive layer is etched to form a gate on the gate dielectric layer. Hence, the dielectric layer thickness can be controlled; thereby the capacitance of the storage capacitor can be controlled.
