Title: Sun tracking device for solar heat collector
Inventor: TOMOTSUNE TAKEHISA
IPC: F24S50/20
Filed: 1981-05-18
Abstract: PURPOSE:To simplify the construction thereof by a constitution wherein a trestle for the heat collector is supported on the upper end of a rotary supporting trestle stood on a fixed base through a horizontally rotating shaft, the fixed base and the trestle are connected through an universal joint at one end of south side and the supporting trestle is rotated from east to west. CONSTITUTION:The fixed base 3 is fixed horizontally while the supporting trestle 2 is rotated from east to west through a belt 5 by a motor 4 with a reduction gear activated at a constant time in the morning. Here, the trestle 1 for the solar heat collector is adjusted so as to face the true south at noon. When the trestle 1 is faced to the west, a limit switch 3-3 is operated to stop the motor 4 and it is returned to the east side by reversing it until tomorrow morning. According to this method, when the trestle 1 is faced to east or west, a vertical distance between an adaptor 1-2 and the fixing base 3 becomes minimum and it shows the maximum inclination with respect to the horizontal line while it shows the minimum inclination angle when it is faced to the true south. Accordingly, once the length of a connecting rod 6 is selected properly, the heat collector may be moved along the trace of the sun approximately.

Title: Inspection apparatus of printed state of cream solder
IPC: G01B11/24
Filed: 1992-03-30
Abstract: PURPOSE:To make inspection quick and reliable by a method wherein a light pattern changing in a plurality of phases is applied to a printed circuit board, the position, area, etc. of cream solder are detected from a plurality of image signals and detected data are compared with reference data. CONSTITUTION:A controller 9 sends a signal to an illumination controller 6 and makes an illuminating device 2 start application of stripe-shaped illumination, while making it shift the phase of the pattern by a 1/4 pitch and change it over sequentially. A CCD camera 3 picks up an image of inspection area in each illumination and outputs image signals for four picture frames sequentially. An image memory 8a stores the image signals sequentially. A computer device 5 calculates the height of a reflecting surface of each part on the basis of the four image signals by a phase shift method. Based on the data on the height, a printed region of cream solder 10a being higher than the plane of a printed circuit board 10 is detected and the position and the area thereof are determined. The height of each part is integrated and thereby the amount of the solder 10a is calculated. Each data thus determined are compared with reference data and it is determined thereby whether a printed state of the solder 10a is good or bad.

Abstract: PURPOSE:To reduce the noise level by separating the lining on a steel smoke stack with a separating cylinder, a lining separating tool and a biasing means by suspending a gondola at a suitable height, and eliminate the need of repainting of the outer surface by removing the steel reinforcement in the lining at the same time. CONSTITUTION:The lining 3 on the steel smoke stack 2 is separated with a separating cylinder 19a, a lining separating tool 20 and a biasing means 21 by a gondola 4 suspended in a smoke stack 1 at a suitable height. Then, rotary plates 6 are rotated horizontally at a predetermined angle along with the separat ing too, etc., and such a separation process is repeated. After completing the separation at that height, the gondola 4 is lowered by one pitch, and the separa tion processes are repeated to remove the lining 3. Therefore, there is no need to use a crusher, and the noise level can be reduced, allowing the separation work to be continued at night or early morning. Further, by removing the steel reinforcement 23 in the lining at the same time, then outward deformation of the steel smoke stack 2 can be prevented, eliminating the need of repainting the outer surface.

Title: Optical module variable in optical characteristic
Inventor: KAJIYAMA SHINICHI
IPC: G02B6/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide an optical module small in size and variable in optical characteristics without being affected by disturbance. SOLUTION: A magnetic field producing means produces a magnetic field to apply an attractive force and a repulsive force to a metal plate 13 on an optical waveguide substrate 1 and tensile or compressive stress to the surface and inside of an optical waveguide, and the optical waveguide substrate 1 is finely deformed to vary the optical characteristics. When the magnetic field producing means comprises a coil 9 and a current adjusting means, the magnetic force can be varied by adjusting the current flowing to the coil 9 and then the optical characteristics can be varied. An optical waveguide substrate with a thin metal film can be formed by vapor-depositing a metal film on a substrate which is made of the same material with the optical waveguide substrate 1 and thinner than the optical waveguide substrate 1.  When the optical waveguide substrate 1 is fixed to a storage tray 6 with an elastic adhesive, it becomes easier to finely deform the optical waveguide substrate 1.
