Abstract: PROBLEM TO BE SOLVED: To make it possible to constitute simply a III nitride semiconductor crystal layer, which is favorable as the luminous layer of a buried laser diode having regions of different refractive indexes (forbidden bands) in the same layer. SOLUTION: This element is a III nitride semiconductor light-emitting element provided with a III nitride semiconductor crystal layer consisting of an AlXGaYAs1UNU (0<=X<=1, X+Y=1 and 0<U<=1) layer formed by substituting one part or all of the arsenic (As) being contained in a III-V compound semiconductor growth layer consisting of an AlXGaYAs (0<=X<=1 and X+Y=1) layer for nitrogen. Here, the III nitride semiconductor light-emitting element is constituted so that a first crystal region 120 of 0.60<=U<=0.98 of the compositional ratio (U) of nitrogen and a second crystal region 121, which is adjacent to the horizontal direction in parallel to the region 120 and has the compositional ratio (U) of nitrogen >=2% less than that of the region 120, are made to inhere in the same layer, and the light-emitting element is provided with the crystal layer as its luminous layer.

Title: Center line detector
Inventor: NOSO KAZUNORI
IPC: G06T7/60
Filed: 1988-10-03
Abstract: PURPOSE:To calculate center positions between corresponding points as a point of a center line by obtaining relative angle data from an original pattern using a point of maximum variation as the reference to allow clockwise and counterclockwise relative angle data to correspond to each other by DP matching. CONSTITUTION:A picture including the original pattern whose center line should be detected is converted to an electric signal and is inputted by a picture input means 1. A pattern detecting means 2 detects the outline of the original pattern from the inputted picture. A relative angle data detecting means 3 obtains the difference between the angle of a line connecting each point on the outline and a clockwise adjacent point and that connecting this adjacent point and a next clockwise adjacent point and the difference between the angle of a line connecting each point on the outline and a counterclockwise adjacent point and that connecting this adjacent point and a next counterclockwise adjacent point as clockwise and counterclockwise relative angle data respectively. A center line calculating means 4 uses a point of quick angle change of relative angle data as the start point to perform DP matching, and every two points including duplicate points out of points of respective relative angle data are allowed to correspond to each other, and the center point between two points is obtained as a point of the center line.

Title: Industrial robot
Inventor: FUJIMORI HIROAKI
IPC: B25J9/06
Filed: 1987-09-30
Abstract: PURPOSE: To facilitate the maintenance and inspection of a driving system so as to easily demount a driving mechanism by unitizing this driving mechanism of an industrial robot, and forming it into a separate structure from an arm and its supporting structure. CONSTITUTION: At a time when an electric motor 1 and a driving mechanism unit consisting of a reduction gear 2, a driving shaft 3 and so on are subject to maintenance and inspection, a connection lying between the driving shaft 3 and a first arm 4 is taken off, removing the driving mechanism unit from this first arm 4. Next, another driving mechanism unit so far prepared in advance is attached to the first arm 4, and this troubled driving mechanism unit is made into maintenance service. Thus, since the driving mechanism unit is formed into a separate structure from the first arm 4 and its supporting structure, the maintenance and inspection in time of trouble happening in a driving system can be easily done in a short time.

Title: Semiconductor device
Inventor: MIYAMOTO TAKAYUKI
IPC: H03K19/0175
Filed: 1987-09-29
Abstract: PURPOSE:To easily execute the common connection of plural devices by connecting a latch circuit, which is inverted by an output from an output edge, to the output terminal of a three-state output circuit. CONSTITUTION:When an OE1 signal of a device(Dvc) 1 goes to be a low level at a time T1 in a semiconductor device, either transistors(Tr) 1 or 2 goes to be a low resistance and output data 'D1' of the Dvc1 is outputted. Thus, respective latches 20 of the Dvc1 and a DVc2 are forcibly inverted so as to be the same logical value as the data 'D1'. The OE1 signal of the Dvc1 goes to a high level condition at a time T2 and the Tr 1 and the Tr2 go to a high resistance condition, however, the data 'D1' are latched and since outputs 14 and 16 hold the 'D1', a synthesizing output holds the 'D1'. After a time T3, the same operation as the operation at the times T1 and T2 to the data 'D1' is repeated to data 'D2', 'D3' and so on. Thus, without paying special attention to the timing of the OE signal, the common connection of the plural devices can be easily executed.

The non-fixed part 5" selected and transposed on the supporting member 2 forms a real image 4 obtd. from the interlace type multilayerd layers with the ink. As a result, the illicit use of original merchandise is well suppressed.

Title: Toner for electrostatic charge image development
Inventor: SUEYOSHI TOSHIYUKI
IPC: G03G9/09
Filed: 1989-09-25
Abstract: PURPOSE:To improve copying quality and to decrease toner splashing by incorporating a carbon black, aniline black and binder resin into the toner. CONSTITUTION:The toner contains the carbon black, the aniline black and the binder resin. There are usually correlations in the amt. of the carbon black to be added, image density and toner splashing when only the carbon black is used as a coloring agent. The image density increases but the toner splashing increases when the amt. of the carbon black to be added is increased. On the other hand, the toner splashing arise hardly but the coloring power is weak and, therefore, the image density is insufficient when only the aniline black is used. The relative content of the carbon black is, therefore, lowered by making combination use of the aniline black as the coloring agent. The toner splashing is decreased in this way and the deterioration in the image is substantially prevented in spite of the repetitive use. The good images which are high in density and are less stained are thus obtd. at all times.

Abstract: PURPOSE:To attain high speed transmission with one optical fiber by converting digital information comprising a binary signal into a 4-value optical signal having 4 kinds of light intensity levels and sending the converted signal. CONSTITUTION:Digital information comprising a binary signal is converted into a 4-value optical signal having 4 kinds of light intensity levels and sent. For example, a 4-value optical signal is converted into a 4-value coded signal corresponding to 2 symbols of 4-value signals having 8 kinds of binary signal 2-bit. In the kinds, 2 kinds of signals are selected to be 4-value signal 2 symbols in which levels taken by 1st and 2nd symbols are inverted and the remaining 4 kinds are converted as 2 kinds 2 sets of 4-value signal 2 symbols whose levels are inverted at a same level and the same kind of 4-value 2 symbols with respect to the same binary signal 2-bit are used alternately. Thus, high speed transmission is attained by one optical fiber by the transmission of digital information in a 4-value optical signal and in the case of a close distance especially, the transmission by space medium is attained without use of an optical fiber.

Inventor: FUNATO TAKAYUKI
IPC: H01M4/62
Filed: 1992-08-25
Abstract: PURPOSE:To obtain a sealed lead-acid battery, which has the excellent charge and discharge efficiency and the excellent charge receiving property and the excellent sealing reaction efficiency and a long lifetime, by specifying a range of the specific surface area and the addition quantity of carbon to be added in the negative electrode active material. CONSTITUTION:The negative electrode active material obtained by adding 1-5weight% of carbon, of which specific surface area measured by the BET method IS 30-150m<2>/g, to the lead powder quantity is used. In a sealed lead-acid battery, since the electrolyte quantity is little and the electrolyte is fixed for non-fluidization, even if the addition quantity of carbon is increased, carbon is not isolated, and a sealed lead-acid battery can be used under the condition that the carbon is held in the negative electrode active material. Consequently, a sealed lead-acid battery, which has the excellent charge and discharge characteristics and the excellent charge receiving property and the excellent sealing reaction efficiency and a long lifetime, can be obtained by increasing the carbon addition quantity in the negative electrode active material.
