Title: Employing CCD and laser sensor for IC pins inspection
Inventor: WANG TUNG-YI
IPC: G01R31/00
Filed: 1997-10-04
Granted: 2000-02-11
Abstract: The invention provides a kind of inspection method for IC pins by CCD and laser sensor. The CCD and laser sensor employ movable fixture and computer control to be moved in the horizontal and vertical direction of disks. The CCD will capture IC images and transmit them to computer for measuring the reference distance between IC pins and IC substrate, pin pitches and positions of pins and used to inspect the horizontal arrangement of IC pins and reference distance whether they are good product. The horizontal and vertical coordinate position of pins is inspected from CCD. Use laser sensor to irradiate laser beam on IC pins from the highest of horizontal to the lowest of vertical or the lowest of vertical to the highest of horizontal areas to detect all the vertical height in the area, and transmit data to computer to calculate the average height which is then compared with the stored data to detect the vertical height of IC pins for achieving rapid inspection function on IC pins in the disk.

Title: Hydroponic device using bubble buoyancy to promote nutrient circulation
Inventor: YANO KENSUKE
IPC: A01G31/00
Filed: 1997-11-07
Granted: 1999-09-11
Abstract: The present invention relates to a hydroponic cultivation device using bubble buoyancy to promote nutrient circulation, which is an upright device, different from the conventional horizontal style, characterized by erecting hollow cultivation tube with multilayer radial-shaped growing pores at the periphery in the nutrient storage tank. The cultivation tube is deployed with nutrient transfusion pipe inside stuffed with non-woven fabric as cultivating medium in between them. Also, the bell-shaped orifice at the bottom of the transfusion pipe is inserted with the feeding duct of the air pump; when the air pump is turned on, the nutrient inside the storage tank rises to the top of the transfusion pipe by the action of bubble buoyancy, and then flows back to the storage tank through the cultivating medium, and the process forms a cycle to nourish the plants planted on the growing pores. Due to the inclusion of air, the nutrient volume increases which accelerates the growth of plants. The device also has other advantages, including the fact that its upright style takes smaller space and the device produces higher yield per unit area and can be easily managed.

The voltage-regulating circuit (2) is fed with a supply voltage (VBAT) and a regular voltage (V0) is defined as the difference between the drive voltage (VBAT2) and the supply voltage (VBAT). Parallel with the voltage-regulating circuit, an external device (8), e.g. a resistance, is connected in order to divert an undesired power generation in the voltage-regulating circuit through the whole or part of the supply current of the user being led to the external resistance and there the whole or part of the power generation is emitted.

Title: Process for making double metal cyanide catalysts
Inventor: COMBS GEORGE
IPC: C08G65/26
Filed: 1998-03-21
Granted: 2000-09-21
Abstract: A process for making substantially non-crystalline double metal cyanide (DMC) catalysts having improved activity and performance is disclosed. The process comprises using a metal salt having an alkalinity within the range of about 0.2 to about 2.0 wt.% as metal oxide based on the amount of metal salt to prepare the catalyst. Surprisingly, important polyol properties such as viscosity and unsaturation improve when the alkalinity of the metal salt used to make the DMC catalyst is properly controlled. The process allows catalyst producers to enjoy the benefits of substantially non-crystalline DMC catalysts even when relatively inexpensive, technical-grade metal salts are used to make the catalyst.

Granted: 2000-10-01
Abstract: A compound switching matrix (30) operates in cooperation with a resistance measuring system (20) and a laser (22) to quickly and accurately trim resistors (12) to predetermined values while they are being measured. The compound switching matrix is implemented with dry reed relays (34-81, 101-164) and includes a probe switching matrix (90-97) and a configuration matrix (32) that reduce the average number of relay contacts required per probe to implement two-, three-, and four- terminal measurements with or without guarding. Moreover, the separate probe switching and measurement configuration matrices effectively separate the high and low sides of the measurement to reduce the effects of stray resistances and capacitances on measurement speed and accuracy. A switchable grounding configuration (82-89) further improves measurement accuracy. The compound switching matrix of this invention enables sequential resistance measurements of individual resistors in the array, with two-, three- and four-terminal measurement configurations being adapted to resistors having values ranging from less than 0.1 ohm to greater than 100 Megohms.
