Patent JP-H0795772-A (JP)
Title: Controller for three-phase voltage type pwm inverter
Inventor: YAMAKAWA TAKAYUKI
IPC: H02M7/48
Filed: 1991-11-21
Abstract: PURPOSE:To increase the output capacitance of an inverter by using felatively easily available triangular waves as third harmonic waves and optimizing the amplitude of the triangular waves. CONSTITUTION:Three-phase sine-wave voltage commanding signals eA, eB, and eC are connected to a three-phase full-wave rectifying circuit constituted of a diode bridge. The potential at a point A becomes the maximum-values signals eH of each phase and the potential at another point B becomes the minimum- value signals eL of each phase. When the sum of the signals eH and eL is taken, semi-triangular tri-frequency harmonic wave signals having an amplitude which is 1/2 of that of fundamental waves can be obtained. At the time of using the harmonic waves, gain resistances R5, R6, and 7, are adjusted to pi/12 of the peak value of third harmonic wave voltage commanding signals to optimize the harmonic wave signals. Therefore, the peak value of the voltage commands can be minimized and the output capacitance of an inverter can be increased by increasing the output voltage of the inverter.

Title: Method for inspecting wiring pattern and apparatus therefor
Inventor: TSUJIMURA SHOJI
IPC: G06T7/00
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To judge with a small count of necessary memories at high speed, by eliminating a characteristic code showing a linear pattern among characteristic codes and comparing the remaining characteristic codes. SOLUTION: A binarizing means 5 converts an image obtained by an image input means 4 having a CCD camera 1 to a binary image 101, and a specific shape-detecting means 6 detects corners of a wiring pattern or the like as a characteristic code. A characteristic code row-generating means 8 couples characteristic codes with eliminating the characteristic code showing a linear pattern, thereby generating a characteristic code row. A comparing judging means 10 compares the characteristic code stored in a good characteristic code memory means 7 with the characteristic code related to a printed board 3 to be inspected, thereby judging whether or not the printed board is good. Since the unnecessary characteristic code showing a line is eliminated when the characteristic codes are obtained and the amount of data to be processed is restricted to a required minimum, an inspection speed is improved and a count of memories is reduced.

Title: Nursing deodorizing device
Inventor: HASHIMOTO MASUMASA
IPC: F24F3/16
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a nursing deodorizing device which is convenient to eliminate an uncomfortable feeling and odor produced during a nursing time for a bedridden old people or the like. SOLUTION: The nursed 100 is attended so that the lower half of the body may be covered with a odor diffusion cover 83. The air prevailing in the cover 83 is introduced to a deodorizing device by way of ducts 85a and 85b so that the air may be circulated in the ducts. Ozone deodorizing is attained by an ozone generation unit while deodorizer components, such as veboteck and phytoncide are added in a deodorizer generation unit, thereby circulating the components so as to eliminate odor attached to beddings or the like. This construction provides a deodorizing device which does not allow the order to be diffused outward in a room and keeps clean, thereby benefiting a care taker and the nursed.
