Title: Manufacture of semiconductor laser diode element
Inventor: HORIKAWA HIDEAKI
IPC: H01S5/227
Filed: 1982-08-09
Abstract: PURPOSE:To improve the performance of a laser element by a method wherein the condition for N-InP growth is alleviated by utilizing the solid phase diffusion of Zn when a Zn doped P-InP is grown. CONSTITUTION:A P-InP substrate 11 is etched to mesa form, and the N-InP 12, the Zn doped P-InP 13, an InGaAsP active layer 14, and the N-InP 15 are epitaxially formed in liquid phase. At the time of forming the layer 12, the mesa upper side is much narrower than the bottom side and slow in growth; therefore the solid phase diffused layer 16 of Zn is generated at the time of forming the layer 13, and accordingly the N-layer at the mesa upper side changes into a P- layer. On the other hand, since the layer 12 is thicker than the upper side, a part without Zn diffusion remains at the bottom of the mesa. The solid phase diffusion of Zn is generated also in the active layer 14, but does not come to influence the characteristic of oscillation. When the Zn diffusion comes to the N-layer 15, the inversion to P type is prevented by increasing the carrier concentration of the layer 15. This constitution enables to alleviate the condition for the growth of an N-InP block layer, improve the performance of a laser element, and thus simplify the manufacture thereof.

Title: Intrusion body monitor device
Inventor: TSUKAHARA MASAYUKI
IPC: H04N7/18
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To shorten a processing time and adaptively determine a threshold for deciding the extent of weather variation by comparing variance of the density historgram of pixels of a difference calculation result between a back ground image and an input image from a camera with the mean or center value of past variance which is several times before. SOLUTION: An arithmetic part 3 generates the difference image between the previously generated background image and the image inputted from the camera of an image pickup part 1. While a trespassing body decision part 4 extracts and decides a intruding body from the difference image, the difference image is used to update the background image by a background update part 6. The arithmetic part 3 calculates the density histogram of the difference image to obtain the variance of its distribution. Then this variance is compared with the mean (center value) of the difference image of several past frames from a data memory 5. When the difference is sufficiently large, it is considered that the weather has changed suddenly, and the background image is renewed by the background update part 6.

Title: Spindle motor
Inventor: OSADA AKIHIRO
IPC: H02K21/22
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a spindle motor which can suppress the deterioration of its dust flowing-out preventing effect, and the motor characteristic of which is not deteriorated remarkably even when the thickness of the motor is reduced. SOLUTION: In a spindle motor 1, first and second ball bearings 5 and 6 are respectively fitted in the front end side and base end side of a fixed shaft 3. A hub 8 is rotatably supported by the shaft 3 through the bearings 5 and 6. A very narrow clearance 15 is formed between an outer peripheral surface 621 of an outer ring 62 of the bearing 6 and a cylindrical projecting section 22 of a frame 2. Since the axial dimension of the bearing 6 is larger than that of the bearing 5, the clearance 15 and bearing span can be secured longer while the spaces occupied by the bearings 5 and 6 are suppressed to the minimum. Therefore, the deterioration of the dust flowing-out preventing effect of the motor 1 can be suppressed and, at the same time, the characteristic of the motor 1 is not deteriorated remarkably even when the thickness of the motor 1 is reduced.

Title: Press bonding postcard with watermark
Inventor: OKAMURA SHOTARO
IPC: G09F1/04
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To improve a forgery preventive effect by providing a watermark partly on a postcard obtained by folding a plurality of folding one side parts connected by a folding line and press bonding them. SOLUTION: A sheet 1 of the postcard is formed of three folding piece parts connected by a plurality of folding lines 3a, 3b, and formed with watermarks 2a to 2c at the respective piece parts. The piece parts of both sides are folded on a central folding piece parts to form a watermark 2 expressing one design (e.g. a character of a 'watermark') by the watermarks 2a to 2c. Then, the expressed design is not limited to the character, but may be combined with a graphic form or the character and the graphic form. Since the watermark 2 can express the design having meaning only after folding but does not mean how the watermarks 2a to 2c are disposed in a press bonded state, its forgery preventive effect can be improved.

Title: Binarization method of read signal from data memory medium and apparatus therefor
Inventor: KANAI TOSHIO
IPC: G11B20/10
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To exactly binarize a read signal by reproduction of a correct bit string and to reduce a bit error rate at the time of reproduction by evaluating phase error at the intersection point of the read signal from a data memory medium and a slice signal. SOLUTION: A DVS arithmetic circuit 32 generates the slice signal. A level comparator 33 receives the read signal 31 from the data medium and the slice signal from the DVS arithmetic circuit 32 and detects the intersection point of the read signal and the slice signal. A phase comparator 34 selects a time cell in which the detected intersection point is included. The comparator detects the phase difference between the center of this time cell and the intersection point. The time cell is subjected to feedback control by a digital PLL 35. An arithmetic processing circuit 36 evaluates the likelihood from the time cell in which the intersection point is included by using a binarization method using the method of least squares, etc., and using the detected phase difference. The circuit selects the time cell into which the intersection point is required to be included. As a result, the reproduction of the correct bit string information is made possible.

Filed: 1984-07-04
Abstract: PURPOSE:To reduce the effects to be exerted on accuracy in working component parts and that in assemblage, by using a carriage roller and a carriage rail in place of an auxiliary shaft for a carriage. CONSTITUTION:The carriage roller 7 rolls while sliding on a lower surface part of a U-shaped configuration of a rail part 9, thereby restraining a rear part of the carriage 1 from being turned downward with a carriage shaft 3 as an axis. The width of the lower surface part of the rail part 9 is set to be sufficiently larger than that of a sliding surface of the roller 7. Accordingly, even when the position of the roller 7 is deviated in the direction from the carriage 1 toward the platen 5 or in the opposite direction, the width of the lower surface part of the rail part 9 is sufficiently large of compensating for the deviation, so that the roller 7 can not slip off the rail part 9.

Filed: 1989-05-30
Abstract: PURPOSE:To obtain detection output without generating phase distortion by subtracting the output of a multiplier at a state where a reference signal generating means issues no output from the output in which the orthogonal transformation of a reception signal is performed with a first or second reference signal. CONSTITUTION:The first reference signal or the second reference signal with a different phase, or a signal with ground level is inputted to the multiplier 44 corresponding to the switching operation of a change-over switch SW. When the first or second reference signal is derived, orthogonal transform output with the reception signal is derived from the multiplier 44, and is stored in a corresponding storage area in a storage means 49. Also, when no reference signal is outputted, proper DC voltage output is derived to the multiplier 44, and is stored in the corresponding storage area. Arithmetic means 82 and 83 subtract a DC voltage component from the output in which the orthogonal transformation of the reception signal is performed based on the storage content of the storage means 49, and the detection output is computed based on the orthogonal transform output from which the DC voltage component is eliminated. Thereby, the detection output without generating the phase distortion can be obtained.
