Title: Picture signal processing method for picture input device
Inventor: NAKAJO HIDEKI
IPC: G06T1/00
Filed: 1989-12-21
Abstract: PURPOSE:To eliminate the mirror surface reflected light component out of a signal showing the picture density and to improve the picture reading performance by providing a prescribed white blind sector area at the white color side from the limit value of the black color side of an electric signal and converting an output signal in the blind sector area into an electric signal showing a prescribed black color. CONSTITUTION:The signal corresponding to the picture density and received from an image pickup element 6 is stored in a ROM 12 via an A/D converter 11. The address of the ROM 12 is designated in accordance with the signal received from the converter 11 based on a command of a CPU 13. Then the output data of the address is transmitted a picture output signal. A white blind sector area is provided to the output data on the ROM 12 in the prescribed width at the white color side from the limit value of the black color side of an input signal. In the blind sector area, an output signal is turned into a signal showing a prescribed black color.

Title: Electric field discharge type electron gun
Inventor: OBARA KENJI
IPC: H01J37/073
Filed: 1989-12-21
Abstract: PURPOSE:To prevent an emitter from colliding against a leading electrode and from deviating from the optical axis during flashing, by forming coaxially a guide hole into which an emitter is inserted and a center hole which is provided in a leading electrode. CONSTITUTION:An insulation member 6 has a guide hole 5' having the same diameter as a center hole 5 of a leading electrode 1 and the member 6 is installed almost lying on the electrode 1 for each hole axis to conform. When a tungsten filament 3 is heated for flashing an emitter 2, the filament 3 is expanded while the emitter 2 is transferred toward the electrode 1. In this case, the emitter 3, if swayed sideways by heating, is transferred along inside the center hole 5 toward the electrode 1 as it is, while the emitter 2 is transferred in the opposite direction after the flashing to return to the position before the flashing. This enables the prevention of the emitter 2 from deviating from the optical axis. This emitter 2 can be prevented from colliding against the leading electrode 1 and from deviating from the optical axis when a supporting member is expanded during the flashing.

Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a capillary and improve the chemical stability of the capillary by making an ionic polymer having positive charges and another ionic polymer having negative charges to be alternately adsorbed on the internal wall of the capillary. SOLUTION: An ionic polymer having positive charges and another ionic polymer having negative charges are made to be adsorbed on the internal wall of a capillary so that the polymer having positive charges (or negative charges) may become the innermost layer. The capillary is that used for capillary electrophoresis, the connection between gas chromatography and mass spectrometry, etc., and can be applied to the infusion analysis, etc., of mass spectrometry.

Title: On-vehicle radar
Inventor: KISHIDA MASAYUKI
IPC: G01S13/931
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To obtain highly accurate information on target from the searching results of target by FM-CW system. SOLUTION: A target 22 is searched by transmitting a search signal 40 for every constant angular interval while scanning through an antenna 23. The transmission angle of the search signal is shifted in the reciprocal search. The direction of the target 22 can be detected as accurately as at the time when the target is searched at a fine angular difference by combining the results of search obtained by repeating scanning a plurality of times while shifting the angle. Relative movement of the target 22 incident to a plurality of times of scanning is regarded as Doppler shift and the data are combined while taking account of frequency shift. Uncombinable data is handled as unnecessary reflected data and a position, where unnecessary reflected data concentrate, is judged as the shoulder of a road.  The height of a stationary target is also judged from the variation state of reflection signal level at the time of approaching it.

Title: Seal device for preventing flow-out of grout between pile and sheath and application method thereof
Inventor: NISHIZAWA TETSUO
IPC: E02D5/50
Filed: 1989-12-22
Abstract: PURPOSE:To exhibit a large sealing effect by fixing a hollow annular seal member made of a resilient material and having an angular cross-sectional shape, to an annular metal plate fixed to the inner surface of a sheath. CONSTITUTION:An annular seal member 4 which is made of a resilient material such as rubber, synthetic resin or the like, having a substantially angular cross- sectional shape and having a hollow part 4c, and which has an inner diameter smaller than the diameter of a pile, is fixed to an annular metal plate 3. The inclination of a slope surface 4a of the annular seal member 4 on the side on which the pile 5 enters is made to be more gentle than the inclination of a slope surface 4b on the opposite side. Further, after the annular metal plate 3 in the seal device 1 is fixed to inner surface 2a of the sheath 3, a pile is driven into the sheath 3. Further, grout is charged and filled in the space between the pile 5 and the sheath 3 through a grout charge hole 3b formed in the sheath 3. With this arrangement, the annular seal member 4 is deformed following a distortion or a deviation of the sheath 3 or the pile 5, and further, a relatively large compression pressure is produced to exhibit a seal effect.

Title: Automatic delivery controller for sheet paper
Inventor: HIGUCHI MITSUHIRO
IPC: B65H23/192
Filed: 1987-12-29
Abstract: PURPOSE:To stop completely a motor when a predetermined length of paper is delivered by providing a position detecting means for detecting a position in which the delivery speed of sheet paper is decelerated and a speed change- over means for decelerating the delivery speed of sheet paper by the output signal of said position detecting means. CONSTITUTION:A delivery roller 20 is driven by activating a motor 21 so that a sheet paper 17 is sequentially delivered from a delivery port 23 onto a toilet seat 12 while moving on a movable plate 24. When a first detecting aperture 33 in the sheet paper 17 is detected by a sensor 31, the sensor 31 generates a pulse. Pulses generated from a speed change-over circuit and the gate signal sent to a switching are generated with the interval being expanded and the rotational frequency of motor 21 is reduced to about one third of normal one. When the sensor 31 detects a second detecting aperture 34, the output from the speed change-over circuit 45 is stopped to shut off current to the motor 21. As a result, the second detecting aperture 34 is stopped immediately after it passes on the sensor 31.

Filed: 1987-12-29
Abstract: PURPOSE:To prevent a one-dot line from being cut and thinned by enlarging the diameter of a light beam spot when adjacent picture element information is non-irradiation information, or when picture element information being adjacent to one side and picture element information being adjacent to the opposite side are both non-irradiation information.

Abstract: PURPOSE:To enable mounting two bare chips in an occupied area necessary to mount one bare chip, and improve the mounting density of bare chips, by fixing a first and a second bare chips with adhesive agent so as to face each other, and connecting the respective bumps with one ends of inner leads. CONSTITUTION:A first bare chip 2 and a second bare chip 4 which are so stacked that bumps 3 and 5 face each other are provided.

Abstract: PURPOSE:To prevent a check seal from hard collision with a stopper member by dividing a cylinder body into a rod side oil chamber and container chamber by the check seal provided on the outer periphery of a rod body to afford gradually communication between the oil chamber and container chamber as an extending force of the rod body is increased. CONSTITUTION:A cylinder body 1 is formed with a small diameter portion 10 and a rod body 2 is provided with a check seal 4 by which the cylinder body 1 is divided into a rod side oil chamber A and container chamber C. The check seal 4 has a main lip 4b and auxiliary lip 4a formed with a notch 4d. While first the container chamber C communicates to the oil chamber A through a communicating path L and the notch 4d, both chambers C, A communicate to each other only through the notch 4d after the check seal 4 moves to the stop member 6 side to close the communicating path L. Thus, since the movement of the check seal 4 to the stop member 6 side is slowed down by the fluid resistance of the notch 4d, hard collision can be avoided.
