Title: Vortex flow fan
Inventor: ARAI KAZUMITSU
IPC: F04D23/00
Filed: 1989-09-14
Abstract: PURPOSE:To reduce fan noise by providing one casing containing a runner and another casing having an air inlet hole and an air blowout hole in a groove along the shape of the runner, and by arranging a buffle member in a part of the groove facing the air blow-out hole of the latter casing. CONSTITUTION:A runner 2 is rotated by a motor 4 along an annular groove 14. Air is taken into the annular groove 14 from an inlet hole 11, and is carried upto a buffle member 17 along the annular groove 14 with its pressure rising. At the buffle member 17, the carried air and the runner 2 are separated into one casing 3 side and another casing 5 side. In this case, blades of the runner 2 passes under the bufflemember 17 and arrives at a partition part 13. Then, the blades arrives at an air inlet hole after passing under the partition part 13. On the other hand, the air separated to another casing 5 side by the buffle member 17 blows out from an air blow out hole 12. By above-mentioned constitution, a fan noise can be reduced.

Title: Electrically driven blind
Inventor: MATSUZAKI YUKINORI
IPC: E06B9/322
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a constitution in which necessary electric energy to be supplied from an external power supply can be restricted. SOLUTION: As a motor drive part 4 supplies a pulse current to a motor, the motor is rotated. As the motor is rotated, a blade 27 ascends or descends. Immediately after the pulse current, that is immediately after the current is supplied from the motor drive part 4 to the motor, and when the current is not supplied to the motor, dynamic braking to the motor is conducted. In the dynamic braking, a transistor 15 is turned on, so a current flows from the motor through the transistor 15 and a constant-current circuit 17 to a secondary battery 6. The secondary battery 6 is thus charged. As the braking is conducted, therefore, braking is applied to the motor, and the secondary battery 6 is further charged. The secondary battery 6 supplies power to a micro-computer 5.

Patent JP-S6393209-A (JP)
Title: Driving voltage generating circuit
Inventor: ISHIKAWA SHIGENOBU
IPC: H03H7/24
Filed: 1986-10-07
Abstract: PURPOSE:To improve the dullness of an LCD driving waveform by providing dividing resistances, which are provided in parallel to obtain an LCD driving reference voltage, and a switch which connects these resistances to select the resistance value of dividing resistances. CONSTITUTION:Dividing resistances 1 and 2 have the same resistance value and are connected in series. The voltage between points A and B and that between points B and C are equal because of dividing resistances 1 and 2. A variable resistance 3 is connected in series with dividing resistances 1 and 2. Dividing resistances 4 and 5 have the same resistance value and are connected in parallel with dividing resistances 1 and 2 by an incorporated interlocking switch 6, and the value of dividing resistances is determined by turning-on/off of the switch 6. The voltage between points A and B and that between points B and C are kept equal independently of turning-on/off of the switch 6. The voltage between points A and C is adjusted by the variable resistance 8 so that it is the threshold of an LCD. Since the resistance value of dividing resistances is changed by turning-on/off of the incorporated switch, the dullness of the LCD driving waveform is improved.

Title: Movement detection circuit
Inventor: YADA ATSUO
IPC: H04N19/50
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To effectively avoid the influence of noises and to surely detect the movement by accumulatively adding plural picture data before or after the comparison of plural picture data corresponding to continuous frames. SOLUTION: The movement detection circuit judges the overall movement of a digital video signal detected by plural movement detection parts 21 and switchably controls the movement of a selector circuit. A comparator 26 in each movement detection part 21 detects the existence of a change between the image data Da, Db of continuous frames and the direction of the change and an adder 27 adds the output data of the comparator 26 to output data from a register 28. The register 28 feeds back the output of the comparator 26 to the adder 27 and outputs the output to comparators 29, 30. The output data of the comparator 26 are accumulatively added in each block of the digital video signal by the adder 27 and the register 28, and when the pictures of respective blocks are changed in a direction increasing a luminance level, the number of pixels increasing the luminance level is detected.

Title: Air bag cover
Inventor: LUTZE WALTER
IPC: B60R21/2165
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To manufacture an air bag cover so that it may be almost invisible from crewmen by leaving a web between blind holes with a weakened line where perforations of the blind holes not to perfectly pierce are linearly put side by side. SOLUTION: In a composite material composed of the three layers of a wooden fiber layer, a foam material layer and a synthetic resin film, since the tearing strength of the synthetic resin film is small, the depth of a weakened line 1 reaching the inside of the foam material layer is enough to surely and quickly break the composite material. The weakened line coincides with a prearranged breaking line 2, and has a profile which is, for example, rectangular or decided by an air bag itself or suited to the shape of an instrument panel, and the air bag folded at the fracture time of the weakened line 1 can be spread out without interruption.

Title: Substrate conveyor
Inventor: TSUDA TATSUHIRO
IPC: B65G1/00
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable substrate conveyor with the low cost and space saving. SOLUTION: A substrate detection sensor 30 detects the presence of an arrival of reflected light from a reflection mirror 28 through a substrate accomodation member 14. Hereby, there is in fact detected the presence of transmission of light beam (reflected light) upon using the reflected light as a light emission source. It is thus detected whether or not there is existent a substrate W in an object space in the substrate accomodation member 14. Accordingly, the presence of the substrate W can be detected with high reliability, and hence the intensity of light beam can be set to be smaller. Further, a robot arm 26 is vertically moved whereby there is eliminated the need of a vertical movement mechanism of the substrate accomodation member 14.  Moreover, the reflection sensor 28 is provided on the back surface of a door 16 of an accomodation member accomodation chamber 12 where the substrate accomodation member is accomodated so that obstruction of the reflection mirror 28 is eliminated upon replacement of the substrate accomodation member 26.

Abstract: PURPOSE: To detect a defect that is provided on a substrate with a high heat conduction rate and cannot be captured by a normal conduction test by applying a test signal that is a combination of two sinusoidal signals and a DC current signal to a conductor to be tested. CONSTITUTION: A drive signal generator 40 has a first oscillator 44 for giving a sinusoidal signal of AC current at a first operating frequency f1 between 10kHz and 20 MHz and a second oscillator 50 for giving a sinusoidal signal of AC current at a second operating frequency f2 . A DC current signal flowing through an electric path 56, a first AC current signal flowing through an electric path 58, and a second AC current signal flowing through an electric path 60 are summed and are applied to the conductor of a device 62 to be tested. A defect being discovered in the conductor being tested generates an mutual modulation signal, and the signal appears as the voltage signal of the conductor, thus detecting a defect that exists in a thin conductor being provided on a substrate with a high heat conduction rate and prevents a normal current flow.
