Title: Method and apparatus for compressing video signal and method and apparatus for expanding video signal
Inventor: SUGAWARA TAKAYUKI
IPC: H04N19/182
Filed: 1989-07-28
Abstract: PURPOSE:To trace a steep change in horizontal and vertical directions and to reduce gradient overload noise by selecting three prediction modes of horizontal linear, vertical linear and 2-dimension so as to control a gain switching circuit. CONSTITUTION:Three data, that is, a data resulting from a pre-data being an output of an adder 4 through a delay circuit 10a for timing adjustment, a nearly 1H delay data through a delay circuit 6a and a nearly (1H-1) picture element delay data being an output of a delay circuit 5a are inputted to a prediction mode deciding circuit 11a. The prediction mode deciding circuit 11a takes the absolute value of the difference of the three data in the horizontal and vertical directions based on the quantity and switching signals of three prediction modes of horizontal linear, vertical linear and 2-dimension are outputted to control gain changeover circuits 7a, 7b. Thus, the tracking to a rapid change in the vertical and horizontal directions is enhanced and the gradation overload noise is reduced.

Title: Dry collection of mesitylene trinitrile
Inventor: KOOTANI ITSUO
IPC: C07C67/00
Filed: 1981-12-04
Abstract: PURPOSE:To collect the titled compound useful as a synthetic intermediate of mesitylene isocyanate, in high yield and purity, by cooling the gaseous reaction mixture obtained by the ammoxidation of mesitylene, under specific conditions. CONSTITUTION:A gaseous mixture obtained by the ammoxidation of mesitylene and containing mesitylene trinitrile is introduced into a solid collection apparatus composed of a cooling chamber maintained at 200-60 deg.C, preferably 150-100 deg.C, a cyclone, a bag filter, etc. to collect the objective compound.

Title: High transmissivity spherical electrode and energy analyzer
Inventor: KUROKAWA AKIRA
IPC: H05H7/00
Filed: 1994-07-28
Abstract: PURPOSE:To improve the transmissivity of charged particles and, further, improve the reproducibility of the angle distribution of the charged particles by a method wherein a plurality of spherical blocking electrodes which have respectively different diameters and have a plurality of holes are provided concentrically and the centers of a plurality of the respective holes of a plurality of the blocking electrodes which correspond to each other are on the same radial lines from the concentrical center point of the blocking electrodes. CONSTITUTION:A high transmissivity spherical electrode is composed of an inner spherical electrode 21 and an outer spherical electrode 22. Charged particles are emitted from the center point 23 of the spherical electrode. The center of a hole 22A formed in the electrode 22 is on a line connecting the center of a hole 21A formed in the electrode 21 to a concentrical center point 23. The apparent angle of the hole 22A against the concentrical center point 23 is equal to or larger than the apparent angle of the hole 21A. Therefore, charged particles which pass through the first spherical electrode 21 can pass through the hole 22A after the hole 21A without fail, so that the transmissivity of the charged particles can be improved. Further, if the positions of the electrode holes of all the analyzers produced are identical, the angular distributions of the holes through which the charge particles can pass are also identical.

Title: Manufacture of resin sealed type semiconductor device
Inventor: ARAKI KOJI
IPC: H01L21/60
Filed: 1987-08-07
Abstract: PURPOSE:To reduce the size of a pellet and to cut manufacturing costs by applying a special method for a conductive metallic pad which is provided on a surface of semiconductor substrate basing a resin sealed type semiconductor. CONSTITUTION:Pads 4 formed on a surface of semiconductor substrate 1 are placed apart each other as they approach the end of each side along the flow of molten resin layer to avoid a pressure to a metal fine line 5 from the melt plastic layer which is put to a tubulous gate 7 placed at one side of a cavity 6 which contains the semiconductor 1, and the interval of pads 4 placed at the side corresponding to the gate 7 is minimized. Because the pad intervals are large at a section having a large angle of incidence theta in this way, contact between a capillary 8 and the metallic fine line are avoided. Where an angle of incidence theta in inverse direction is large, pitch can be minimized; therefore, the size of pellet, that is, semiconductor substrate, can be thus reduced.

Title: Registration method of data and its retrieval method
Inventor: NAGAISHI TOMIO
IPC: G06F7/24
Filed: 1990-07-25
Abstract: PURPOSE:To reduce the retrieval time by comparing one preceding data string with a data string to be registered this time and registering number of same data starting from a head of the data string together with the data string to be registered as additional information. CONSTITUTION:A number SC of same data starting from a head of a data between one preceding data string and the data string R to be registered this time is registered while being added as additional information to the data string to be registered this time. For example, the number SC of the same data being additional information of a first registration data string A is O, and since number of coincident data from the head of the data between a succeeding data string B and the 1st data string A is 5, the SC=5 is registered. Similarly, additional information is added to the data string to be registered. Thus, the data string is retrieved by referencing the data number SC and no retrieval processing is implemented to the same character string and the retrieval time of the data string is reduced with simple processing.

Title: Obstacle-recognizing device for vehicle
Inventor: SHIRAI TAKAMASA
IPC: G01S13/931
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To provide an obstacle-recognizing device which can recognize an obstacle other than a preceding vehicle by accurately distinguishing the obstacle by utilizing its ability of recognizing obstacles in the height direction by on the assumption that it is an obstacle recognizing device of such a type that three-dimensionally recognizes obstacles. SOLUTION: The obstacle recognizing device performs road-side object eliminating processing after the device judges a preceding vehicle based mainly on that the object exists in the same lane as that of its own vehicle. When the center height of an object is higher than 4.0 m ('yes' in S120) or nearly 0 m ('yes' in S130), the device recognizes that the object is not a preceding vehicle (S210). However, when its own vehicle runs on the ending part of an ascent, the device has a possibility of erroneously recognizing a signboard or a mark which is set up at a higher position and rightfully recognized as a road-side object by the device as a preceding vehicle, because such a case that the signboard or mark exists on the road in front of its own vehicle.  Therefore, when an object exists at least once in an area, which is not accessible by an ordinary vehicle during a prescribed period of time from two seconds before to the present time, the device judges that the object is not a preceding vehicle (S140-S190).

Title: Optical pickup device
Inventor: HONMA OSAMU
IPC: G11B7/135
Filed: 1987-08-07
Abstract: PURPOSE:To increase the emission power of a laser source and to stably read information by shifting off the optical axis of the laser source from the center of an aperture. CONSTITUTION:The optical axis of the laser diode 1 is shifted off the center of the aperture i.e. the diode 1 is inclined clockwise. When the laser diode 1 is thus inclined, the proportion of the quantity of the light that passes through the aperture 8 to the whole quantity of emitted light from the diode 1 is reduced. Accordingly, if the quantity of the incident light on a photodetector 7, that is, the output signal level of the detector 7 is constant, the emission quantity of the laser diode 1 can be increased. Thus the emission power of the diode 1 can be enhanced, and information can be read accurately.
