Title: Component for optical information recording, reproducing and erasing
Inventor: OTA TAKEO
IPC: G11B7/24
Filed: 1989-01-23
Abstract: PURPOSE:To improve cycle characteristics for bit error property by causing symmetric thermal expansion in a heat-resistant layer in the front and rear parts of a mark when the mark is formed by melting, with the intention of preventing the material transfer accompanied with melting of the recording thin film material. CONSTITUTION:The component consists of a lower heat-resistant layer, a recording thin film layer and an upper heat-resistant layer. In the process of forming the mark by melting the film with laser light, the front and back parts of the mark in the heat-resistant layer are made symmetric thermal expansion. These films are crystallized by irradiating with laser light to heat and by gradually cooling. By irradiating these crystallized films with high power laser light to heat over the melting point thereof, the heated area melts and rapidly cools to an amorphous state, which forms a mark. By selecting the constitution of layers and the method for heating, thermal expansion of the heat-resistant layer can be reduced and thermal expansion in the front and rear parts of the mark is made symmetric with less difference of expansion. Thus, deterioration of the component for recording caused by material transfer in the record ing thin film can be prevented.

Title: Optical waveguide device and control method
Inventor: DOI MASAAKI
IPC: G02F1/313
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a practical optical waveguide device capable of adjusting a perfect coupling length of a double mode optical waveguide by utilizing thermooptic effect. SOLUTION: This method is to control a perfect coupling length between zero-degree mode light and first-degree mode light propagating in a double-mode optical waveguide composed of a material having thermooptic effect. An area along the center line of the double-mode optical waveguide is heated up in order to vary a propagation constant of zero-degree mode light, while the heat of both side areas of the area along the center line is radiated to prevent the propagation constant of the first-mode light from varying due to the heating.

Title: Collision magnitude detecting method, seat belt device and air bag device
Inventor: YOSHIDA RYOICHI
IPC: B60R21/0136
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To detect the collision magnitude of a vehicle in a short time after a collision by detecting a collision speed from the change of detected acceleration with the lapse of time, and detecting the collision magnitude from the time difference between the time until the collision speed reaches a first set value after the collision is detected and the time until the collision speed reaches a second set value. SOLUTION: This air bag device 4 deploys an air bag 5 with four inflators 6-9. When a vehicle 1 collides, acceleration is detected by an acceleration sensor 2, and a collision speed is calculated by a control unit 3 from the change of the detected acceleration with the lapse of time. The inflators 6-9 are operated by the control unit 3 in response to the size of the collision speed. The control unit 3 feeds the current from a battery 1 to the igniters of the inflators 6-9. The control unit 3 controls the number of the inflators 6-9 to be operated in response to the collision speed. The collision speed can be detected in a short time after a collision even if the collision speed is large.

Title: Operating cylinder with automatic orifice
Inventor: HATSUTORI KAZUHIKO
IPC: B60P1/16
Filed: 1978-02-10
Abstract: PURPOSE: To surely stop the spontaneous motion of a piston due to a pull-out phenomenon without hindering the ordinary operation, by automatically reducing the cross-sectional area of a drain-side oil port only when the pull-out phenomenon has occurred.  
     CONSTITUTION: When a piston rod 6 is moved forth and the load is drastically decreased, such a pull-out phenomenon occurs that the piston 7 moves spontaneously. At that time, the pressure of a chamber A becomes negative and the pressure of another chamber B rises over an ordinary level. Therefore, a poppet valve 15 moves left and the port 12 is shut off by a sleeve 23 to restrict the working oil flowing out through the port 12. Thereby, negative pressure is applied to the piston 7 so that the piston is blocked from moving spontaneously. The pull-out phenomenon ends in a short time. Therefore, the pressure of the chamber A rises again, the poppet valve 15 moves right and a cylinder 4 continues to move forth at an ordinary speed.

Title: Character segmenting method
Inventor: AOKI MIKIO
IPC: G06K9/34
Filed: 1989-01-24
Abstract: PURPOSE:To exactly segment a character from a character picture in an undetermined form by finding out a segmenting position from the value of peripheral distribution only when a candidate segmenting position does not exist at the time of character extraction. CONSTITUTION:A CPU 101 segments the character one by one from the character picture, which is read by a picture input device 102, in a RAM 105. At first, the standard character height of the character and the tickness of a line are estimated from the peripheral distribution in a row direction and next, a standard character interval, word interval and standard character width are estimated and the extraction of a word is executed. Then, the candidate character segmenting position is estimated. For the segmentation of the character in the extracted word, the like component of the character is extracted and simultaneously, the height and width of the character are extracted. When the width of the character exceeds an allowable size, the extraction of a contour is executed again. When the candidate character segmenting position does not exist, a candidate character segmenting range is determined according to the peripheral distribution in a direction vertical to the row direction and the extraction of the contour is executed again. Then, only the inside of the area is extracted and the character is segmented. Thus, the character picture in the undetermined form such as the character picture, in which the peripheral distribution is overlapped, etc., can be exactly segmented.

That is, it is stopped while decreasing its speed of rotation and the water discharge rate gradually, so that water hammer phenomenon is not caused even if the discharge pipe is fairly long. Further, since the flywheel 11 is not exposed in water, trouble such as loss due to resistance of water and entangling of foreign matter will not occur.
