Title: Central air-conditioning system temperature control method with intermittent fan control
Inventor: SHEU DER-BIN
IPC: F24F11/02
Filed: 1997-04-10
Granted: 1998-05-01
Abstract: A temperature control method with intermittent fan control for a central air conditioning system includes mainly the following steps. A temperature sensing step for sensing the room temperature. A temperature readout step for read out the setting of the room temperature. A calculation step for calculating the temperature difference by comparing the results from the previous two steps. A fan control step for controlling the air flow based on the calculation results from the previous step. And a blower motor control step which links to the previous step for controlling the operation of the blower motor. The features are as follows. The fan control step includes a continuous fan mode and an intermittent fan mode. The fan control step drives the blower motor in the continuous fan mode when the temperature difference between the actual room temperature and the room temperature setting from the calculation step is greater than or equal to a standard value, but drives the blower motor in the intermittent fan mode to blow air intermittently at a low speed when the temperature difference between the actual room temperature and the room temperature setting from the calculation step is less than a standard value.

Title: Working machine with the function of detecting wear of a tool
Inventor: SHIOZAKI MASAHITO
IPC: B23Q17/09
Filed: 1997-04-22
Granted: 2001-01-21
Abstract: The present invention is to provide a working machine with the function of detecting wear of a tool. The working machine includes a load meter, an A/D converter, a comparator, and an operation portion to monitor the present consumed power PW1 of the built-in motor for driving the main shaft, to compare with the preset basis consumed power PW2. During the processing procedure, when the present consumed power PW1 is greater than the basis consumed power PW2, it is detected that the tool is worn out. The main shaft is supported by the static pressure bearing. Thus, the tiny variation of the consumed power can also be detected, such that the wear detection can be proceeded accurately.

Title: Apparatus and method for estimation range
Inventor: CATHEY JR WADE THOMAS
IPC: G06K9/36
Filed: 1997-09-26
Granted: 2000-02-01
Abstract: Range or distance to points is estimated within a scene, while simultaneously imaging the scene. The range to various points within the scene is  estimated by imaging at least a first color of light from the cene through an optical mask and a lens onto a CCD, and digitally processing the first color light intensity values stored in the CCD. At least a second color of light passes through the mask essentially unchanged and is separated from the first color of light before reaching the CCD and used for imaging the scene. The optical mask is designed such that the optical system transformation matrix for the first color of light is rank deficient for a particular set of object ranges. In this way, linear functions can be found to annihilate given sample image data at a plurality of ranges, independent of the intensity of the light received from the object. A statistical detector is used to determine the closest associated range to the actual range of the point within the scene.

Title: Magnetic fluid thin film displays, monochromatic light switch and tunable wavelength filter
Inventor: HUNG HENG-E
IPC: H01F1/44
Filed: 1998-03-20
Granted: 2000-12-21
Abstract: Methods for preparing homogeneous magnetic fluid compositions capable of forming ordered one dimensional structures or two dimensional lattices in response to externally applied magnetic fields are disclosed. The compositions are prepared using improved co-precipitation methods in which the steps of the procedure have been tuned to reduce sample heterogeneity. Fe3O4 particles are coated with a surfactant and dispersed in a continuous carrier phase to form these homogeneous magnetic fluid compositions. The ability of these compositions to generate ordered structures can be tested by holding a magnet near a thin film of the compositions and observing the formation of colors in the region near the magnet. Methods for controlling the characteristic spacing of the ordered structures formed by the composition also are disclosed. Relevant parameters include the thickness of the film, the strength and orientation of the externally applied magnetic field, the rate of change of field strength, the volume fraction of the magnetic particles dispersed in the continuous phase, and the temperature of the homogeneous magnetic fluid. The homogeneous magnetic fluid composition is useful for the manufacture of liquid crystal devices. The devices take advantage of the serendipitous fact that the spacings in the material are on the order of the wavelength of visible light. A variety of magnetic-optical devices can be constructed that use the ordered structures to diffract, reflect, and polarize light in a controlled and predictable manner. These devices include color displays, monochromatic light switches, and tunable wavelength filters.

Title: Color sorting apparatus for granular material
Inventor: SATAKE SATORU
IPC: B07C5/342
Filed: 1998-08-11
Granted: 1999-12-01
Abstract: A granular material sorting apparatus consists of a transfer device, an optical detector, an injection nozzle, and a control unit. The transfer unit is responsible for making material grains fall down; an optical detector unit is mounted along the falling path of the material grains; an injection nozzle device is for injecting air to the material grains; and a control unit for controlling the operation of the injection nozzle. The nozzle control unit responses to detection made by the optical detector unit. The optical detector and control unit optically detects and discriminates colored grains and foreign matters mixed in other grains whose colors are different from good grains or transparent. It then activates the injection nozzle device in a predetermined period of time after the detection to remove the detected bad grains. The control unit sets different injection duration and different injection delay times depending on whether the bad grains are colored grains or foreign matters.

Title: Method of defining passivation pattern
Inventor: CHEN SHR-SHIUNG
IPC: H01L21/30
Filed: 1998-11-16
Granted: 2000-11-11
Abstract: This invention provides a method of defining passivation pattern using photo sensitive polyimide film, which will form cross-linked structure after exposure, instead of positive photoresist used by traditional passivation etching to transfer the bonding pad pattern. After etching, the polyimide film is remained as stress buffer for subsequent packaging. The method can effectively solve the passivation crack and photoresist extrusion problem, and form the polyimide film without exposure and development step. Therefore the manufacturing cost is reduced.

Title: Base station transmit power control in a CDMA cellular telephone system
Inventor: BUTOVITSCH PETER
IPC: H04B7/005
Filed: 1999-01-11
Granted: 2001-08-01
Abstract: A power control method in accordance with the present invention synchronizes the transmit power levels at the base stations currently serving a mobile station and an initial transmit power level of a new target base station being added in a diversity handover situation. At the beginning of the handover, a radio network controller orders the serving base stations to measure their respective transmit powers to the mobile station. Each serving base station then measures its transmit power to the mobile station and reports the power level measurements to the radio network controller. An initial transmit power setting is determined for the target base station, and new transmit power settings are determined for the serving base stations synchronized for example to a particular time (t0). At or about synchronizing time t0, the target base station transmits to the mobile station at the initial power setting, and at or about the same time, the serving base stations preferably also adjust their transmit powers toward the new values. Alternatively, the serving base stations transmit at their respective new values at or about time t0. In a preferred embodiment of the present invention, the serving base station power adjustment is performed gradually.
