Title: Process for producing expandable graphite
Inventor: WENG BIING-JYH
IPC: C01B31/04
Filed: 1998-08-13
Granted: 2002-01-01
Abstract: This invention relates to a process for producing expandable graphite. The process consists of treating graphite particles with acid to form graphite intercalation compounds, rapidly heating the graphite intercalation compounds at a high temperature to obtain vermiform expanded graphite. The vermiform expanded graphite is for production of flexible graphite and for absorption of various liquids. The features of the invention is as follows: (1) after mixing of graphite with acid, the acid is removed by centrifugal operation and then the graphite is washed with water, avoiding product of much heat due to reaction of acid with water. This step enhances safety and quality of the product, (2) if the proportion of the graphite particle is increased, high expansion of graphite is still obtained, (3) the removed acid can be recycled to reduce cost and to meet the requirement of environmental protection.

Title: A virtual ground type semiconductor storage device
Inventor: OHTA YOSHIJI
IPC: H01L27/115
Filed: 1998-09-04
Granted: 2001-05-16
Abstract: In a virtual ground type semiconductor storage device, all of memory cells connected to one word line in blocks of eight memory cells are read in four sense operations. In each read operation, three consecutive main bit lines (BL) are discharged by a discharge signal (dis) and two memory cells (MC) which are each connected to both a discharged main bit line and a charged main bit line are used as read memory cells, whereby the influence of a leak current from both the adjacent memory cells on the read memory cells is suppressed to the minimum. Among adjust cells (AC) activated by an adjust signal (awl), ones (AC) connected to only the charged main bit lines are designed as programmed cells (P) to reduce a variation in leak current to a sense main bit line due to data retained in the memory cells (MC) connected to only the charged main bit lines.

Title: Foam based product solution delivery apparatus and method for generating a foam based product
Inventor: BREEDLOVE JOHN
IPC: A62C31/12
Filed: 1999-07-14
Granted: 2001-06-23
Abstract: The foam based product solution delivery apparatus is simple in structure and operation and makes use of pressurized gas to power a pressure operated pump to draw the water/foam-concentrate/product(s) from supply tank(s) and propel the resultant solution (foam fluid), with pressurized gas injected therein, through an agitation apparatus that mechanically agitates the water/foam/product(s) solution to create the foam based product solution for transmission to the foam delivery apparatus. Interposed in the delivery apparatus between the pump and the outlet end of the hose, the agitation apparatus functions to significantly increase the foam expansion prior to delivery of the foam through the delivery apparatus. The agitation apparatus comprises an exterior housing inside of which is mounted a set of motionless mixing blades that function to mix and expand the foam. The agitation apparatus not only produces a high expansion of the foam but it also produces a more consistent bubble structure which enhances both the longevity and adhesion of the foam when applied to a structure.

Title: Microwave oven
Inventor: NAKAGAWA TATSUYA
IPC: H01F27/32
Filed: 2000-03-16
Granted: 2001-06-07
Abstract: The subject of this invention is to provide a microwave oven using an inverter power supply of half-bridge type capable of preventing the starting time of a magnetron from becoming long while the dielectric withstand voltage of a booster transformer remains small. Because the primary side of a booster transformer 5 is connected with an inverter power supply of half bridge type, no DC component flows in the primary winding of the booster transformer 5, and its saturate voltage may remain small. The transformer 5 has a core gap 40 consisting of core segments 28 and 29, and because the core gap 40 is positioned on the side with the secondary winding 22, the secondary winding 22 has a reduced self-coupling coefficient, and the self-resonance frequency on the side with secondary winding 22 is shifted to the high frequency side. This enlarges the resistance of the side with secondary winding 22 and lessens the Q value of self-resonance on the side with the transformer secondary winding 22, so that generation of ringing due to self-resonance can be prevented.

Title: Drying apparatus and drying method
Inventor: ONODA HAJIME
IPC: H01L21/00
Filed: 2000-03-28
Granted: 2001-05-16
Abstract: A drying apparatus comprises a drying vessel, a treatment liquid feeder-discharger for feeding pure water into the drying vessel, a vapor supplier for supplying an organic solvent vapor to the space over the pure water, insert gas suppliers for supplying an inert gas with which the organic solvent vapor is diluted, and a heated organic solvent supplier for forming a film of the organic solvent on a liquid level of the pure water. After the wafer is immersed in the pure water, the pure water is gradually discharged from the drying vessel by means of the treatment liquid feeder-discharger. Since the wafer passes through the organic solvent film as it is exposed above the liquid level, the organic solvent of the film adheres to the surface of the wafer, and the organic solvent vapor is condensed on the surface of the wafer that is exposed above the liquid level.

Granted: 2003-03-11
Abstract: The state of a label at an optional time point, such as a past time point, can be recognized, while the label can be regenerated even when the label has been deleted. When a label on which can be pasted an object, such as text, picture or sound, is acted upon (yes at step S141) the difference of the label information is computed (step S142) and the computed difference information is stored (steps S144, S145). The label state is then regenerated based on the time information stored in association with the label and the difference information. Also, time is displayed, plural time intervals are displayed (step S201), a desired one of the plural time intervals is selected (step S202) and time display is controlled responsive to the selected time intervals (steps S203 to S206), to facilitate retrieval of the information corresponding to the specified time. In addition, a label handling at least the time concept is processed (step S231) and the time axis in displaying the label is controlled (step S233) based on an operating signal associated with rotational actuation from a jog dial (step S232).

Title: Hinge
Inventor: FORD JAMES J
IPC: E05D7/10
Filed: 2000-11-08
Granted: 2001-06-23
Abstract: A hinge provides for concealment of the hinge, and for removal of the door leaf from the frame leaf. A spring-biased one-piece pin includes a finger tab between the first and second knuckles of the door leaf. The pin reciprocates between an engaged position wherein it is contained within the first, second, and third knuckles, and a retracted position wherein it is contained only within the first and second knuckles. A frame leaf fits between the second and third knuckles, and is retained there by the pin. A tab having a concave depression at each end, combined with the spring-biasing of the pin so that the finger tab is held within these depressions, ensures that the pin will not move from one position to the other unless it is first disengaged and rotated, thereby securing the frame leaf and door leaf together until separation is desired.
