IPC: H03D7/02
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a harmonic mixer using an anti-parallel diode pair or the like in which a frequency conversion loss from a high frequency(RF) signal into an intermediate frequency(IF) signal is small independently of odd number/ even number harmonics of a local oscillation LO signal.

IPC: F21V17/00
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To easily attach a globe to a tool body by providing overhang parts by the number a multiple of receiver matalfittings to the globe at approximately equal pitches. SOLUTION: Overhang parts 3 are provided from an opening end of a globe 2 toward the center of the opening. The number of overhang parts 3 are a multiple of receiver metalfittings 4, for example twice, three times, and four times and arranged in an opening end at approximately equal pitches, respectively. When the opening of the globe 2 is matched, pushed up and rotated with a device main body 1,the overhang parts 3 are guided by guide parts of the receiver metalfittings 4 to run thereon, supported by the receiver parts, and then installed in the tool body 1. This constitution can reduce the rotation angle in respect to the tool body 1 in attaching the globe 2 so as to facilitate the attachment. For example, in a case of three receiver metalfittings 4, the globe is just rotated by 60 degrees at the most.

IPC: G03B35/00
Filed: 1990-02-26
Abstract: PURPOSE: To prepare a stereoscopic photograph in focus by deciding a distance from a camera to a main object for the pictures of the each set of prints, performing alignment for the first picture of the pictures of the each set by proper registering and moving the negative holding device of a printing device only by an appropriate value between adjacent prints. CONSTITUTION: In the case that an interval between the lenses of the camera and the back focus of the camera are known, the interval between the main objects of adjacent plane pictures is calculated by an equation I for each set of photographing plane picture. In the equation I, S expresses the distance between the main objects of the adjacent plane pictures, F expresses the back focus of the lens of a compound eye camera, T expresses separation between the respective adjacent lenses of the compound eye camera and K expresses the distance between the camera and the main objects. Thus, the stroke distance of the negative holding device of the printing device is adjusted by knowing the S value of each set of the plane pictures, so that the stereoscopic print in focus is prepared.

Title: Method for regenerating carrier
Inventor: TSUDA JUN
IPC: G03G9/113
Filed: 1987-03-02
Abstract: PURPOSE:To regenerate a deteriorated ferrite carrier and to restore the original characteristics by heating the carrier recovered from a developing device to remove substances sticking to the surface and by heating the carrier again to regulate the electric resistance. CONSTITUTION:A ferrite as a magnetic oxide, that is, MFe2O4 (where M is Mn, Co or the like) is granulated and baked to obtain a ferrite carrier. This carrier is mixed with a toner and used for development in a developing device. When the carrier is deteriorated, it is recovered from the device. Air is blown on the recovered carrier to remove toner particles, etc., sticking loosely to the carrier particles. The carrier is then heated to above a temp. at which toner particles, etc., sticking to the surface can be burned. The carrier is heated again to regulate the electric resistance of the carrier particles. By this second heating, the effect of fine ferrite powder produced by overbaking can be eliminated. Since the recovered ferrite carrier is heated in two steps, the properties of the regenerated carrier can be made comparable to those of a fresh carrier.
