Abstract: PURPOSE:To vary the radiation pattern individually by providing a branch wave- guide path for separating a part of the laser beam wave-guided into the main wave-guide path and emitting it outward and by providing an accepted light phase modulation part for varying the phase of the laser beam in a part of said branch path. CONSTITUTION:An n type main wave-guide path 11 is formed into a stripe form on a part of the main plane of the clad layer 2 on an n type crystal substrate 1 to wave-guide a laser beam. A p type active layer 3a is formed on the main plane of the wave-guide path 11 and n type branch wave-guide paths 12a and 12b are formed on the part on the both sides of the wave-guide path 11 on the main plane on the layer 2. The paths 12a and 12b connect with the wave-guide path 11 optically on the side of the end F2 and separate and emit a part of the laser beam from another side of the end F1. Each of the wave-guide paths 12a and 12b is provided with the accepted light phase modulation parts 13a and 13b for varying the phase of the laser beam emitted outward. Furthermore, drive electrodes 14a and 14b are formed corresponding to the modulation parts 13a and 13b to easily vary the pattern of emission toward the outside individually a part from the emission output.

Title: Object lens driving device
Inventor: MATSUNO TOSHIKI
IPC: G11B7/09
Filed: 1983-06-28
Abstract: PURPOSE:To reduce the man-hour for adjustment and the cost of parts by joining at least two magnetic material yokes into one body. CONSTITUTION:Yokes and a base are formed into one body by the sintering formation method using magnetic materials or the like to obtain a yoke base 10.

Title: Display device
Inventor: KUGOU MASARU
IPC: G01F9/02
Filed: 1981-07-29
Abstract: PURPOSE:To precisely display available travelling distance by storing the upper and lower limit values of a mean fuel cost value in a controlling computer and operating the upper limit value or the lower limit value as the mean fuel cost value when the calculated mean fuel cost value exceeds said limit values. CONSTITUTION:A car speed sensor 7 consisting of a photosensor is connected to a controlling computer 1 and the information selected by key switches 16-22 is displayed on a display element 2 through driving ICs 29, 30. An output from a fuel sensor 34 is inputted to a comparator 33 and a connection line to the IC30 is connected to the other input terminal of the comparator 33 through a buffer 31. The upper and lower limit values of a mean fuel cost value are previously stored in the computer 1. When a mean fuel cost value calculated from the travelling distance and the used volume of fuel does not exceed said limit values, the available travelling distance is calculated on the basis of the calculated mean fuel cost value and, in case of exceeding the limit values, the available travelling distance is calculated by regarding the upper limit value or the lower limit value as the mean fuel cost value, preventing the incorrect calculation of available travelling distance due to the inclination of a fuel tank.

Title: Straight permanent wave agent
Inventor: SASAKI YOSHIHIRO
IPC: A61K8/86
Filed: 1995-04-18
Abstract: PURPOSE: To obtain a straight permanent wave agent having excellent combing with a slight damage to hair and high straight effect by mixing a highly polymerized polyethylene glycol. CONSTITUTION: Either or both of a primary agent and a secondary straight permanent wave agents are mixed with 0.01-10wt.% of a highly polymerized polyethylene glycol having a molecular weight of >=2×10<4> , preferably (300-400)×10<4> . The primary straight permanent wave agent contains a reducing agent (e.g. thioglycolic acid) as a main agent and an alkali agent (e.g. ammonia), etc., to cut a disulfide bonding of cystine contained in keratin protein in hair by reduction, then makes hair a straight state by applying a physical force by combing, etc. The secondary agent contains an oxidizing agent (e.g. bromate) and regenerates the disulfide bonding to permanently fix the straight state. By mixing the highly polymerized polyethylene glycol, the straight state can surely be preserved.

Title: Apparatus for detecting position
Inventor: TANAYA HIDEO
IPC: G05D3/12
Filed: 1987-05-14
Abstract: PURPOSE:To make it possible to detect a position with high accuracy and to align positions with a crossed table driven, by detecting a plurality of edges by application of horizontal and vertical projection integrations to picture data picked up by a TV camera, and by averaging same. CONSTITUTION:A TV camera 4 picks up a close-contact type image sensor as an object 1 and makes it binary-coded, thus obtaining right and left pictures and storing same in a memory. When the whole of the pictures are subjected to projection integration in the vertical direction, subsequently, a sharp fall is found in an end part X0 of the sensor and it can be detected as an edge. When the fore end part of a left sensor is denoted by X1 and that of a right sensor by X2, therefore, the absolute value DELTAX of the difference between X1 and X2 is a positional slippage between the left and right sensors in the horizontal direction. Next, the projection integration is applied in the horizontal direction, and beltlike edges Y1, Y2...Y8 are detected thereby and averaged. The absolute value DELTAY of the difference between the left and right averaged values thus obtained is the positional slippage in the vertical direction. Accordingly, the crossed table 2 of the right sensor is driven on the basis of DELTAX and DELTAY and thereby the positional alignment thereof with a fixed stage 3 of the left sensor can be conducted.

Title: Painting-out circuit
Inventor: SHIRAISHI NAOHITO
IPC: G09G5/36
Filed: 1990-05-08
Abstract: PURPOSE:To perform the painting-out the inside of a closed graphic with high accuracy in a short time by provicing a line vector generation circuit, vector direction calculation circuit, outline selection circuit, line drawing circuit, painting-out circuit, and memory. CONSTITUTION:Summit coordinates X and Y of the graphic to be painted out are inputted to a vector generation circuit 1, to generate start/end point information and vector parameter. A direction calculation circuit 2 receives this, deciding the rotational direction of the drawing. An outline selection circuit 4 selects an outer-most point. A line drawing circuit 3 makes a dot showing a line segment by algorithm from the start/end points of the line segment and the vector parameter. Only the outer-most dot is transmitted to a picture memory 6 with the painting-out circuit, etc., by the outline selection circuit 4. A painting-out circuit 5 paints out the distance between the selected two outline dots according to edge flag algorithm to write them in the memory 6. These sequence of operations are performed under the control of a control circuit 7. At the time of the line drawing, since the drawing is performed after dividing them into right and left side ones in the direction of the line vector, the optimum boundary start/end point can be obtained, and the processing can be processed in short time with high accuracy because the distance between two points are painted out.
