IPC: G06T7/60
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for estimating the distance (vertical distance) from a camera to a point being measured on an object based on an image picked up by means of a single camera. SOLUTION: A single camera 11 having known angle of view α is arranged such that the optical axis L is normal to a reference plane 13a and the distance R thereto is known. An object A is disposed in front of the camera 11 and moved by a specified distance (r) in parallel with the reference plane 13a within the image pickup range 15 of camera 11. Image of the object is picked up by means of the camera 11 before and after movement. Moving distance a+b of the object reflected on the image is then determined from the position of points P1 , P2 corresponding to a point P to be measured on respective images thus picked up.  Finally, the distance from the camera 11 to the point P being measured is estimated based on the size (v) of image, moving distance a+b, distance R from the camera 11 to reference plane 13a, reference image pickup range D depending on the distance to reference plane 13a and angle of view αand the moving distance (r) of object.

Title: Dry-type electrophotographic device
Inventor: HIRAI KUNIO
IPC: G03G15/16
Filed: 1987-12-09
Abstract: PURPOSE:To always obtain the best printing quality even if the kind of paper is changed by automatically changing the transfer voltage of a transfer part in accordance with the kind of paper in response to the switching operation of a printing mode. CONSTITUTION:When a mode switching switch 17 is set on the side of a post- card mode, a post-card mode signal (a) is outputted to cut off a transistor 34. When a transfer signal (b) is inputted, a voltage regulator IC 35 is actuated and a higher DC output voltage is outputted from an output terminal 42. For example, when the ordinary paper of A4, B5 and a letter size, etc., is used, transfer is performed with 5.0kV transfer voltage and when the thick paper such as a post-card etc., is used, the transfer is performed with 5.3kV transfer voltage. Thus, the transfer voltage in case of printing on the post-card which is thicker than the ordinary paper is automatically raised. Thus, the best photographic printing quality can be always kept even if plural kinds of paper, whose kinds of thickness and quality, etc., are different, is used.

Abstract: PURPOSE:To make the construction simple and eliminate unnecessary defrosting time by detecting the return current which is the sum of the current value after a set time has elapsed and a set current value corresponding to the current frequency and detecting exactly the completion of defrosting. CONSTITUTION:When the defrosting operation is started and the frequency of the electric power source is inputted, a set current value I1 corresponding to the frequency is stored in a memory. Then a first timer-count counts the specified time T1. When the elapse of the time T1 is judged at a LSI 24, the operation current I is read by a current detection circuit 9, and the operation current I0 after the time T1 has passed is stored in the LSI 24. Further, the addition of the specified current I1 and operation current i0 which are stored in the LSI is made and the sum is stored as a return current I2. Now, in the LSI 24 it is judged whether or not the operation current l is smaller than the return current I2; if the condition I>=I2 is met. a second timer-count is set and the counting of the time T2 is started. And, if I>=I2 again, it is judged that the time T2 has passed, and if the time T2 has passed, signal of finished defrosting is issued.

Title: Jet solder bath
Inventor: SATOU ITSUSAKU
IPC: B23K1/08
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To make the height of a jet to part fixed even if a jetting pressure is high, by holding both ends of a floating body by a spring, enabling a floating body to float only in the lateral direction, and restricting the floating in the longitudinal direction. SOLUTION: Jet solder is fed from below and jets from a jet port 1, and flows out of a pair of nozzle plates 2, 2. Since a floating body 5 is set in molten solder, so-called kalman flow is generated in a flow in a rear part of the floating body 5 and the floating body 5 is moved up and down, and right and left. However, since both ends of the floating body 5 are held by flat springs 6, 6, lengthwise floating is restricted though it floats breadthwise. Therefore, molten solder jetting from the jet port 1 propagates in unspecified directions due to turbulence by eddy flow of kalman and breadthwise floating of the floating body 5. Since the floating body 5 does not float up and down at all in a top part of molten solder jetting from the jetting port 1, a fixed height can be always maintained.

Title: Steel plate-made flywheel and its manufacture
Inventor: AOKI TOSHIHIDE
IPC: B21D19/08
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To press a steel plate so as to provide a mass part on the periphery. SOLUTION: A flywheel 5 has a mass ring 13 wound in a flat spiral form on the periphery. The mass ring 13 can be provided by a process for forming a shallow cup in the central part of a disc and then bending the edge from the outside in two positions, and a process for gathering the bent parts to the side part of the cup. Since the bent parts are formed by one-way bending work, the draft is low so that cracking can be prevented. Further, since the mass ring 13 is turned in the axial line direction, another member can be arranged on the inside thereof, and the mass ring 13 can be set in a space substantially having only the plate thickness in the axial line direction.
