Title: Spread spectrum communication system
Inventor: KATO MASAKAZU
IPC: H04B1/707
Filed: 1994-01-25
Abstract: PURPOSE:To prevent the performance of a radio system from being lowered by providing high transmission speed by transmitting/receiving a specified code as a spread code while specifying a code length when a binary state is made correspondent to '0' and '1'. CONSTITUTION:A multiplication part 4 performs code modulation to binary data outputted from an input data reception part 1 and a spread code read from a spread code storage part 2 synchronously with a clock signal outputted from a clock signal generation part 3. A modulation part 6 outputs a modulated signal for which a carrier wave outputted from a carrier wave transmission part 5 is modulated (the angle modulation of two phases or four phases is performed) with the signal outputted from the multiplication part 4. This modulated signal is amplified by a high frequency amplifier part 7 and transmitted from an antenna 8 as a transmitting wave. In this case, when the binary state is made correspondent to '0' and '1', the code length is specified at 10 digits, and any one of four codes of 0001110110, 0110111000, 1110001001 and 1001000111 is used as the spread code and transmitted/received.

Title: Carrier tape connector
Inventor: MURAKAMI TAKASHI
IPC: B65D73/02
Filed: 1994-01-25
Abstract: PURPOSE:To easily connect carrier tapes with high repeatability and with sufficient strength secured by rotating an arm with a supersonic cutter device and a supersonic deposition device provided at both ends. CONSTITUTION:An arm 6 is attached to a rotating shaft 5 which rotates 90 degrees counterclockwise and clockwise respectively, while a supersonic cutter device 7 and a supersonic deposition device 8 are provided at both ends of the arm 6. Rotation of the arm 6 moves the cutter device 7 and the deposition device 8 to a predetermined position on a cut/deposition stage 9.

Title: Landslide suppressing method
Inventor: EGUCHI TAKUMI
IPC: E02D17/20
Filed: 1994-01-24
Abstract: PURPOSE:To prevent the occurrence of a land slide through the increase of frictional resistance of a slide surface by a method wherein holes extending to an immobile layer are bored in a plurality of spots of a landslide layer by a boring device and an explosive is set in the position of the slide surface for blasting. CONSTITUTION:Holes 4 extending through a slide surface 3 to the interior of an immobile layer 2 are bored in a plurality of spots of a landslide bed 1 by using a boring device 7. When an explosive is set in the position of the slide surface 3 in the bored hole 4 and explosion, for example, blasting 5, is effected, the shape of the slide surface 3 is changed into a complicated shape and a landslide bed 1 is brought into a state to cut through the immobile layer 2. A boundary between the slide surface 3 and the immobile layer 2 is then deformed and frictional resistance of the slide surface 3 is increased. Since the landslide layer l is caused to cut through the immobile layer 2 and slide friction is further increased, the occurrence of a landslide is suppressed. This method facilitates construction, shortens a term of works, and reduces a cost.

Filed: 1993-01-19
Abstract: PURPOSE:To provide a device capable of forming proper tool route data by providing an outline figure memorizing means to work outlines, a tool radius offset means to form a tool center route, and a connection means to connect offset line segments adjacent to and apart from each other. CONSTITUTION:A central processing unit 1 reads an outline figure fox a work range memorized in a memorizing device 3, and offsets it to the inner side of the outline figure for a tool radius to form a figure to be used as a tool center route (Step S1). In the case an out protruding part is offset inward, a part exceeding an intersectional point of an offset line segment is cut. In the case an in protruding part is offset outward, a connection line segment is inserted because adjacent offset line segments are apart from each other. A connection processing is performed by executing a sub-routine. A figure offset outside the outline figure for the tool radius from the figure formed in the step S1 is memorized in the memorizing device 3 as tool route data for outline working, and it is displayed in a display device 5 (Step S2).

Title: Light beam position detector
Inventor: SHIRATAMA KOUICHI
IPC: G01B11/00
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain a light beam position detector which makes up for the occurrence of abnormality in measurement attributed to a photodetecting level. SOLUTION: Levels (a), (b) and (c) of the quantity of light of a light beam is detected by a photodetector 1 in four quadrants. A detection signal of the photodetector 1 is amplified by amplifiers 2, 3, 4 and 5 to be outputted. The photodetecting levels (a), (b) and (c) amplified are computed by an arithmetic device 6 and the total value and the difference value of the results of the computation are outputted. A limiter circuit 7 judges the level of the total value outputted by the arithmetic device 6 and outputs a reference value predetermined when it is below a specified value. A divider 8 has the difference value outputted from the arithmetic device as numerator and the total value via the limiter circuit 7 as matrix to perform a division.  In the division, the total value as matrix is made up for above the specified value, eventually achieving a compensation for the occurrence of abnormality in the output of a light beam position detector. This also improves lower power consumption, accuracy, operability and like.

Abstract: PURPOSE:To drastically increase the current density of ion and minimize the size of whole components including a neutralizing cell by bending the ion beams extracted out of a plurality of ion sources to the same direction and injecting in an acceleration part. CONSTITUTION:Ion beams extracted out of a plurality of ion sources 1 are bended to the same direction with a magnetic field formed by a toroidal coil 2 and injected in an acceleration part 3. The injected ion beams overlap and accelerate each other and therefore, the current density introduced into a neutralizing cell 4 can be drastically increased. Resultingly, the inlet area of the neutralizing cell 4 can be reduced, the length of the neutralizing cell 4 can be shortened, and the whole components can be small-sized. Instead of the toroidal coil, a toroidal coil shape magneic field can be formed with electromagnets or parmanent magnets.

IPC: G05F3/24
Filed: 1980-02-28
Abstract: PURPOSE: To form a circuit suitable to IC implementation and having small variance, by combining only insulating gate field effect transistors.  
     CONSTITUTION: The series circuit of IGFET8 of the 1st conduction type, e.g. p type and IGFET10 of an n type and that of n type FET 9 differing in threshold voltage from FET8 and p type FET11 equal in threshold voltages to FET10 are connected in parallel to power source 6. Both gates of FETs 8 and 9 are connected to the connection point of FETs 9 and 11, and those of FETs 10 and 11 are also connected to the connection point of FETs 8 and 10 to constitute a constant-voltage circuit. Further, the series circuit of load 7 and FET12 is connected to power source 6, whose gate is connected to the output terminal of the constant-voltage circuit. The constant current of the thus constituted constant-current circuit depends upon the conductance constant and threshold voltage of each IGFET, and the variance of those values can be reduced as a result of IC implementation. Thus, the circuit having small variance and suitable to IC implementation can be formed.
