IPC: G01M10/00
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To efficiently make a wave by closing an opening and closing valve, raising a box body by a driving mechanism to raise the internal level higher than the external level, opening the opening and closing valve to introduce the air, and making the water flow to the outside of the box body. SOLUTION: A box body 1 opened in the bottom part is formed of a circumferential wall 1a and a top wall 1b connected to the upper edge, an opening and closing valve 3 for performing the communication and cutoff of outside and inside air is installed to the top wall 1b, and the box body 1 can be raised and lowered by a hydraulic cylinder 4 near the level of a water tank. In the state where the opening and closing valve 3 is opened, the box body 1 is lowered to a position submerged up to the vicinity of the upper edge of the circumferential wall 1a by the operation of a cylinder 4. The opening and closing valve 3 is then closed to raise the box body 1 by the operation of the cylinder 4, and the internal level of the box body 1 is raised higher than the external level.  The opening and closing valve 3 is opened from this state to introduce the air, and the internal level of the box body 1 is suddenly lowered, and the water is made to flow out to generate a wave within the water tank. Thus, the wave can be quickly generated at low cost.

Title: Manufacture of semiconductor laser device with optical fiber and its package
Inventor: BABA TAKAHISA
IPC: G02B6/42
Filed: 1987-07-14
Abstract: PURPOSE:To improve operability by holding the sleeve of an optical fiber outside a package and aligning it at a semiconductor laser, and fusing a metallic fusion material by a heat source which does not contact this material. CONSTITUTION:The optical fiber 23 with the sleeve 25 is inserted into the package 41 through the hollow part of a sleeve guide 49 and its outside part is held by a chuck 51. Then while a semiconductor laser 17 mounted on a mount part 43 emits light, the optical fiber 23 is aligned where the coupling efficiency of the optical fiber 23 is maximum. The chuck 51 is moved to move the sleeve with the optical fiber, but the guide 49 has the hollow part larger than the external diameter of the sleeve 25, so the sleeve 25 is moved in the hollow part to facilitate the positioning. A pellet 47 of the metallic fusion material is mounted in a bridge shape between upper ridges of the projection walls 45a and 45 of an optical fiber fixation table 45. Consequently, the optical fiber 23 is fixed to the fixed base 45 by being fused by projecting light from the heat source which does not contact the material, e.g. a YAG laser.

Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To facilitate an operation for making a new message to a protection state in a state where the number of the protection messages in a radio portable terminal is the largest protection number. SOLUTION: When the number of the messages with the presence of protection attributes, which are not deleted even if they become old, is the largest protection number and the new message is to set to the presence of the protection attribute in the radio portable terminal of a pager system and the like, the message of the presence of the protection attribute at the oldest reception time is displayed on LCD 13. When a rotary switch 4 is turned only the messages of the presence of the protection attributes are displayed on LCD 13 in order from oldest reception time.
