Title: Adaptive focal plane for forming high-contrast image
Inventor: LIVINGSTON PETER M
IPC: G01S7/499
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a high contrast image-forming system having an adaptive focal plane. SOLUTION: A polarized light beam splitter 44 linearly polarizes a 2nd beam 46 of detected target radioactive rays. A beam polarizer 48 circularly polarizes the 2nd beam 46 of detected target radiation. An adaptive focal plane 52, i.e., a micro mirror array, reflects radioactive rays from a circularly-polarized and detected target, transmits the radioactive rays through a beam polarizer 48 in the reverse direction, and linearly polarizes the reflected 2nd beam of the radiation. A detection array 56 detects the reflected 2nd radiation beam 62, and outputs a signal according to an intensity of the radiation to a tracking electronic circuit 22. A tracking electronic circuit 22 adjusts a reflective index of the micro mirror array 52, and guarantees that the radiation made incident on the detection alley 56 becomes a predetermined threshold or below.

Title: Edgeless speaker
Inventor: KIMIJIMA MASAYUKI
IPC: H04R9/02
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To improve the speaker performance of an edgeless speaker by supporting a damper so as to form an eddy current as a whole. SOLUTION: Supporting rings 57, 58 and 60 and their fitting pedestals fitted and fixed onto the upper other peripheral surface of a bobbin 18 and the outer peripheral surface of a cone 16 are connected with the fitting sections of respective supporting members 71 to 74, which are installed corresponding to horizontal positions while obliquely facing these supporting rings and their fitting pedestals, through dampers 31a to 31d, 32a to 32d and 33a to 33d in any specified shape and the cone 16 and the bobbin 18 are supported on frames 14. With such a connection, the top end parts of dampers, etc., are fixed to the supporting rings or the like and the base end parts are fixed to the supporting members 71 to 74 or the like.  Then, all the plural dampers fitted to the same supporting ring are set to the same length so as to be elongated toward the wide opening part of the cone and further fitted so as to form the eddy current as the entire damper by turning the top end part of dampers in almost the same direction. With such a supporting means, the runaway of the cone is suppressed and the vibrations of a voice coil are more exactly propagated to the entire surface of the cone.

Title: Production of piezo electric ceramic
Inventor: ASANO HIROSHI
IPC: C04B35/64
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To produce a dense piezo electric ceramic reduced in pores by suppressing vaporization of PbO in a firing process in the production of a multicomponent piezo electric ceramic consisting essentially of PbO. SOLUTION: Substitution for firing atmospheric gas is conducted for at least 3 times. The firing process is divided into 3 steps and as the 1st step, the oxygen partial pressure in the firing atmosphere in a temp. range, where the shrinkage factor of the ceramic is <=5%, is controlled to 0.1-0.5. As the 2nd firing step, the oxygen partial pressure of the firing atmosphere in a temp. range, where the shrinkage factor of the ceramic is 5-10% and the pore of ceramic is opened to the outside atmosphere, is controlled to 0.2-1.0. As the 3rd step, the oxygen partial pressure of the firing atmosphere in a temp. range, where the shrinkage of the ceramic is 10-25% and the pore of the ceramic is closed to the outside atmosphere, is controlled to 0.1-0.5. Thus, the more dense ceramic sintered compact than that in the case of a conventional atmospheric firing is produced.

Title: Image forming device
Inventor: MENJO TAKESHI
IPC: G03G21/14
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To shorten the time of an image forming by performing a cleaning only at the necessary time, for a transfer material carrying means carrying the transfer material on which the image from the image carrier is transferred. SOLUTION: This device is composed by providing the image carrier on a surface on which the image is formed, the transfer material carrier 5f carrying the transfer material for transferring the image formed on the image carrier, and cleaning means of the transfer material. At this time, if a carrying position of the transfer material in the subsequent time for instance, the A4 size on the transfer material carrier, matches with the carrying position (a) of the A4 transfer material on the transfer material carrier in the previous time, the cleaning work for the transfer material carrier by the cleaning means is not performed, the cleaning is performed when the position dose not match, and thus the time of transition from the previous image forming to the subsequent image forming is shortened.

Title: Colorant determination method in color printing forming black image depending on background
Inventor: ROBAATO EMU KOORUMAN
IPC: H04N1/60
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a digital color printing method automatically altering the black compsn. to a black object by the presence or absence of a background color containing a non-black colorant. SOLUTION: A colorant to be used in the printing of a black area is determined in a system using an electronic signal designating a black or non-black colorant used in a process printing the black area on a background area. This colorant determining method has such a step that the above mentioned signal is tested in order to determine whether or not a background must be printed by using a non-black colorant and, if the non-black colorant must be used in order to print the background, a signal designating that a black color wile be printed using a first black color is generated and if the non-black colorant should not be used in order to print the background, a signal designating that the black color will be printed using a second black color is generated to print the black area.

Title: Sensor for detecting presence of object in continuously repeating operation
Inventor: TEIMOSHII EI SUKUNESU
IPC: G01J1/02
Filed: 1991-12-27
Abstract: PURPOSE: To quickly detect the presence of a drill bit near a drilled surface without retreating the drill bit from the surface by detecting reflected energy intermittently reflected at a frequency which is directly connected with the frequency of continuous repetitive operations. CONSTITUTION: The light from a laser diode 60 is emitted to a drill bit 42 through a strip radiation optics 64. The convergent laser light is reflected from the surfaces of the two recessed spiral grooves of the bit 42 and condensed through a receiving lens 74. The condensed light beams are collected to a solid- state photodetector 70 after the light beams are collimated and filtrated through an optical filter 72. Thus the laser beam is reflected to the photodetector 70 from the surfaces of the two spiral grooves of the bit 42 and gives a transmitting signal having a frequency which is directly connected with the rotating frequency of the bit 42. Therefore, the presence of the oscillation signal of the laser light at a predetermined frequency is detected.

Title: Film detecting device for camera
Inventor: TAKU MASAKAZU
IPC: G03B1/00
Filed: 1992-12-25
Abstract: PURPOSE:To obtain the highest S/N ratio at the time of detecting the perforation of a film by forming a recessed part, which has an almost V-shape cross section seen from the side, on the film rail surface at a position opposite to a photo-interrupter so as to obtain the only reflected light, which is reflected from the film surface, as the reflected light which enters a light receiving part. CONSTITUTION:The infrared light is projected from a light projecting part 1a of a photo-interrupter 1, but since the infrared light is not reflected by the film surface due to the perforation 4b, the infrared light arrives the inclined surface 3a of a recessed part of a main body. Since the inclined surface 3a of the recessed part has the inclination at about 45 degree against the film rail surface 3d, the infrared light is reflected to the light projecting side opposite to a light receiving part 1b of the photo-interrupter 1 to make the output from the light receiving part 11, minimum. Furthermore, since the width A of an opening part of the recessed part is wider than the width of the perforation B, secondary reflection at the inclined surface 3b is hard to be generated. Furthermore, since a film 4 is guided by a film rail 3d at the time of winding and unwinding, the film travels stably to improve the detection of film.
