Title: Laser surveying equipment
Inventor: HIRANO SATOSHI
IPC: G01C5/00
Filed: 1984-03-24
Abstract: PURPOSE:To enable the scan of an object to be surveyed in a horizontal plane irrespecitve of a tilt of the main body of a surveying equipment, by making incident beams from below the emitted constantly in the vertical direction by means of a reflecting member which is suspended by a suspender which is formed in about half of the focal length of a projector lens system. CONSTITUTION:A laser beam emitted from a semiconductor laser 14 is passed through a condenser lens 15, a Porro prism 16, a parallel plane glass 12 and a projector lens 23 and projected upward. Then, it is reflected by a pentagonal prism 31 and emitted horizontally therefrom toward a surveying point, at object to survay, and a scan within a horizontal plane is conducted with the rotation of a rotating shaft 26. Even when any deviation occurs in the direction of emission from the laser 14 due to a tilt of the main body 11 of a machine, the optical axis of the laser beam emitted from the Porro prism 16 is directed constantly in the vertical direction, since the length of a ribbon 19 suspending a suspension board 17 with the Porro prism 16 fixed thereon is set to be a half of the focal length of the projector lens 23.

Title: Image forming device
Inventor: HOTTA YOZO
IPC: G03G15/00
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent soiling of an image due to, for examples, toner scatter around a toner image, which is caused by an insufficiency of transfer bias, and a transfer failure by varying the transfer bias according to the number of consecutively-passed both-sided sheets at the time of image formation. SOLUTION: A printer control part 28 consecutively forms images on the first sides of transfer sheets via a high voltage control part 17. Also, when the number of consecutively-passed both-sided sheets, with images formed consecutively on the second sides of the same transfer sheets, exceeds a specific number, the control part 28 detects increases of the temperature and resistance of a transfer roller 5 which is in contact with a photoreceptor drum 1, and it exerts constant-current control over the transfer roller 5 each time the number of sheets exceeds the specific number. A transfer bias in which a specific voltage is added to the voltage applied at this time is determined by the printer control part 28, and this transfer bias is applied to the transfer roller 5.

Abstract: PURPOSE: To suppress disturbing radiation by winding a conductive tape to the degaussing coil entirely to prevent undesired disturbing radio wave from a deflection circuit, a power supply circuit and a video circuit or the like and the emission of an electromagnetic wave and an electric field wave. CONSTITUTION: A conductive tape 2 being a nonmagnetic material is wound to the outer sheath of the degaussing coil 1. In order to avoid insulation breakdown, an insulation tape 5 is wound in advance.

Moreover, an earthing circuit 6 to connect electrically the conductive tape 2 to ground is provided to apply electrostatic shielding to the coil 1. The conductive tape 2 is used for the outer sheath of the coil 1 and the coil 1 is shielded, then the reduction in the magnetic reluctance is prevented and disturbing radiation from the coil 1 itself is suppressed by keeping the electrostatic shield effect. Furthermore, a metallic case covering a cathode ray tube is not required, the display monitor is made light in its weight.

Title: Surface wave element
Inventor: KADOTA MICHIO
IPC: H03H9/25
Filed: 1988-03-11
Abstract: PURPOSE:To prevent the damage of a leader electrode when a mask is put on an insulated substrate by forming a fanwise swelling part covering the surface of a piezoelectric thin film through the side of the insulated substrate at a place where said thin film crosses the leader electrode. CONSTITUTION:The four dig-in parts 5b continuous to a window hole 5a are etched halfway on the inner surface of a mask 5 touching an insulated substrate 1 at the points where the electrodes 2 and 3 correspond to the leader electrodes 2c and 3c respectively. When the mask 5 is put on the substrate 1 for sputtering, a piezoelectric material formed into a film enters partly the inside of the parts 5b through the outer surface side of the mask 5. Then a fanwise swelling part 4a is formed from the surface of a piezoelectric thin film 4 through the side of the substrate 1 at the positions where the film 4 crosses the electrodes 2c and 3c respectively. Thus the mask 5 never rubs both electrodes 2c and 3c even though the mask 5 has some position error to the substrate 1 when the mask 5 is positioned or the film 4 is formed. As a result, the electrodes 2c and 3c are not damaged.
