Title: Water drop removing device
Inventor: OKADA SHOJI
IPC: B60S1/56
Filed: 1988-09-30
Abstract: PURPOSE:To remove water drops being attached to a plate quickly by heating the plate with heat emitting substance, bending with an oscillator iteratively, and thereby removing attached water drops. CONSTITUTION:When an AC power is supplied from leads 31, 32 to a piezo oscillator 20, a mirror 11 is bent iteratively. If here the frequency of this AC power is selected to an appropriate value, the mirror 11 goes into resonance, and a uniform standing wave with large amplitude is generated in the whole mirror 11. This standing wave puts the reflex surface 11b of the mirror 11 into a high speed motion. At this time, water drops attached to this reflex surface 11b are given a high kinetic energy from the mirror 11 to lead to dropping by their own weight or atomizing to be removed from the surface 11b. The piezo oscillator 20 and a heater 25 emit heat to warm the mirror 11, and clouding etc. thereon is evaporated quickly to give a clear reflex face to the mirror.

Title: Ttl logic circuit
Inventor: NIIYAMA SHINYA
IPC: H03K19/088
Filed: 1990-09-19
Abstract: PURPOSE:To speed up the circuit by serially connecting a damping resistor to a diode to be reversely connected between the output terminal of a high impedance set control part and the base of s phase split transistor. CONSTITUTION:Since a damping resistor 20 is serially connected to a first diode 16, when inverting an output terminal 15 of a high impedance set control part 2 from a low level 'L' to a high level 'H', the vase potential of a phase split transistor 7 is not increased higher that a prescribed level by the coupling capacity of a first diode 16, and this transistor 7 is prevented from being turned on. Therefore, the base voltage of an OFF buffer initial step transistor 9 can be immediately risen from the 'L' to the 'H'. Thus, a time required for moving the output state of a logic circuit part 1 from a high impedance state to the state of the 'H' is shortened, and acceleration is attained.

Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To execute more accurate rotation correction and to realize a high collation rate even if a fingerprint picture is inclined by obtaining the inclination of an input picture by a moment method and correcting data by the inclination quantity. SOLUTION: When picture data are inputted from a picture input device 1, data of an original picture (292×524 pixels, for example) are binarized (S2). Then, the centroid coordinate (XG, YG) of an input picture and the inclination θof the input picture are calculated by a moment method (S3). It is judged whether the obtained inclination θ is in a permission range or not (S4). When it is not in a correction unnecessary range, rotation correction is required (S5). Data on the picture (rotated correction picture) obtained by rotating the original picture by the inclination θwith known affine transformation, around the obtained centroid coordinate (XG, YG) so that the inclination is cancelled (S6), are generated.

IPC: B22D31/00
Filed: 1987-10-03
Abstract: PURPOSE:To reduce production cost by applying a tensile force from the external part as well as electrifying an internal chill metal member and drawing it in the state of its peeling from a casting. CONSTITUTION:Both ends of the metal member B subjected to an internal chill inside a product A is heated by passing a large current by connecting feeding electrodes 2-a, 2-b to the cable 3 of a transformer 1. The metal member B softened by heating with a holding device 4 is pulled by the specified amt. by a cylinder 5 by removing both electrodes 2-a, 2-b. The member B becomes slender and is peeled off from the product A, so it is subjected to a temp. fall in this state to pull out the member B downwards by the cylinder 5. Due to the member B being heated and drawn after applying a tensile force thereon the metal member B can be completely pulled out with a small pulling force in a short time. The production cost of the product A is reduced because the equipment is also simplified.
