Title: Device and method for detecting target in reverberation and recording medium having recorded in-reverberation target detecting program
Inventor: TAKEMURA TAKASHI
IPC: G01S7/536
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To enable an active SONAR device to effectively extract reflected signals from a target in reverberation. SOLUTION: The disclosed active SONAR device is provided with a TVG (time variable gain) amplifying section 4, which sends transmitting signals composed of electric signals to the underwater after converting the signals into acoustic signals, converts underwater acoustic signals into received signals composed of electric signals, and performs gain correction on the received signals based on the time-sequential damping characteristic of reverberation and detects a target from the output of the amplifier section 4. The SONAR device is also provided with a signal processing means 7a which performs target detection from the output error between white noise identified with the reverberation output of the amplifying section 4 and the output of the section 4 based on the received signals.

Inventor: HARADA KATSUHITO
IPC: G01N21/74
Filed: 1990-07-19
Abstract: PURPOSE:To enhance the uniformity in mixing of a sample and a specified material and to improve measuring accuracy by using a sucking/discharging nozzle, and sucking and discharging the sample and the specified material in the order of the specified material, the sample and the specified material. CONSTITUTION:A sample solution 22 is injected into a graphite cell 1. At this time, a specified material 21 is injected before and after the injection of the solution. Thus, the sepcified material 21, the sample solution 22, a standard sample solution 23, a blank solution 24 and the specified material 21 are deposited in this sequence. Thereafter, the cell 1 is heated with an electrode by feeding a current. The cell 1 is dried for a required time. The contact chance between the sample to be measured and the specified material which is the added material is increased in the furnace. Since the mixing degree is substantially enhanced in this way, the measuring accuracy in the flameless atomic absorption method can be enhanced. When the graphite cell which is the heating furnace is preheated, it is not necessary to provide a special step for heating and drying, and the measuring time can be shortened.

Title: Image forming device, intermediate transfer body, and image forming method
Inventor: SETO MITSURU
IPC: G03G15/01
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To reduce the transfer duct generated in color superposition without loosing paper free property by providing a charge imparting means, and imparting a charge of the same polarity with a visual image to be transferred to an intermediate transfer body prior to primary transfer. SOLUTION: A charging apparatus 71 as charge imparting means is arranged on the upstream side of a primary transfer area along the carrying direction of an intermediate transfer belt 19. This charging apparatus 71 imparts a charge of the same polarity as a toner image to be transferred to the intermediate transfer belt 19 prior to primary transfer. Thus, the charge quantity in the image part and ground part on the intermediate transfer body substantially uniforms the charge imparted onto the intermediate transfer belt 19 in the charge imparting position before electrostatic primary transfer, so that the action of a horizontal noise electric field toward the ground part which generates transfer duct can be suppressed. Thus, the action of the noise electric field causing the transfer dust can be suppressed to reduce the transfer dust generated in color superposition.

Title: Image recording and reproducing device
Inventor: ONO HIROYUKI
IPC: H04N5/765
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To allow the user to view immediately a past image just before an image being viewed in real time within a short time by recording cyclically image information for a prescribed time at a past image recording section at all times. SOLUTION: A past image recording section 11 records cyclically image information for a prescribed time at all times. In the case that a selection operation section 12 sets a time and selects a 'past display' mode, a changeover section 14 selects a past information line B from a current information line A. Then a memory read write processing section 19 calculates an address of an image memory 20 storing image information that was recorded in the past corresponding to the set time and reads the image information in the image memory 20 by using the calculated address as a read start address.  The image information is restored to a digital signal before compression by an image signal decoder 21, converted into an analog signal by a D/A converter 22 and the analog signal is given to a display device 16 through an instruction line C via the changeover section 14 and the past image is displayed on a display section 27 in place of the current image.

Filed: 1992-07-20
Abstract: PURPOSE:To detect a paper at a low cost and with high accuracy by providing a paper guide surface with a paper position-regulating protrusion so that the surface of the protrusion extends along the common tangent to the peripheral faces of a feed roller and paper discharge roller. CONSTITUTION:A paper printed by a printing part C is fed to a paper discharge roller 11 along a paper guide surface 9. In this case, the position of the printed paper is regulated by each pair of paper position-regulating ribs 31 so that no fluttering of the paper occurs and the paper can be prevented from coming into contact with the paper guide surface 9. Therefore, even if the paper is thin and ink permeates the rear face of the paper, the ink does not adhere to the paper guide surface 9 so that the paper can be prevented from becoming dirty. Thus, the paper can also be prevented by respective paper position- regulating ribs 31 from fluttering so that a reflection-type photosensor 21 with a small detection range and at a low cost can be arranged in close vicinity to the paper guide surface 9 and the sensor 21 can be used to detect the paper.

Abstract: PURPOSE:To easily allow writing of patterns without impression of electric fields by writing the patterns while utilizing the phase sepn. and change of a liquid crystal which arise according to the polymn. conditions of a high-polymer matrix. CONSTITUTION:The writing of the patterns is executed by utilizing the phase sepn. and change of the liquid crystal which arise according to the polymn. conditions, such as temp. and light intensity, of the high-polymer matrix. Namely, a soln. mixture 30 contg. the high-polymer MA of a polymer or oligomer and the liquid crystal molecules MB is held between supports 32 and 34 and a light shielding mask 36 is formed on the base 32. The soln. mixture 30 is set at such a temp. at which the soln. mixture is maintained at the temp. below the nematic to isotropic transition point of the liquid crystal. The soln. mixture is then irradiated with light which causes a polymn. reaction, for example, UV rays. The polymn. reaction is effected in the part irradiated with the UV rays. The liquid crystal drops MC are then separated in phase and are formed in the high-polymer matrix. The soln. mixture 30 is then set at the temp. higher than the temp. in the process of the previous stage and is irradiated with the light over the entire part, by which the polymn. is effected. The patterns are easily written when the electric fields are not impressed to the soln. in such a manner.
