Title: Activation method for mobile communication system
Inventor: SAKAI AKIRA
IPC: H04W24/02
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To provide the activation method of a mobile communication system capable of performing activation by optimum starting time corresponding to a system scale. SOLUTION: On a line controller side, an operation parameter used for system activation is registered beforehand, optimum standby time corresponding to the system scale is calculated corresponding to the operation parameter and respective base stations BTSes are successively activated based on the calculated standby time. Thus, the system is activated by the time corresponding to the system scale without standing by for fixed time at all times regardless of the system scale as before and thus, conventional useless standby time is omitted and the time required for the system activation is shortened.

Title: Tugging piezoelectric cable
Inventor: OGURA KOJI
IPC: G01S3/80
Filed: 1987-09-03
Abstract: PURPOSE:To prevent an influence due to the bending of a piezoelectric cable and to improve a S/N by connecting respective echo sounder receiving units through an universal joint. CONSTITUTION:A shaft life 2 is formed by connecting many rigid short lines 3 by the universal joint 4a. Piezoelectric echo sounder receiving elements 5a are disposed on the circumference of the short line 3 to constitute the echo sounder receiving unit of the short line and the element 5a. These echo sounder receiving units are connected by the joint 4, inserted into a flexible tube 1, further an insulating oil is filled to constitute the piezoelectric cable. The division electrodes 11a, 11b of the respective elements 5a are connected in parallel to an output terminal 15 by lead wires 8a, 8b. At the time of operating axial force, force orthogonal with the axial direction and bending stress, a signal voltage is not generated from the terminal 15 according to a noise cancel principle. An output signal can be effectively generated to an acoustic wave. Since the element 5a longitudinally extends continuously, a flow noise at the time tugging can be completely suppressed.

IPC: C03B11/00
Filed: 1982-12-20
Abstract: PURPOSE:To obtain an optical element, such as lens or prism, satisfying optical requirements by removing the surface defects of a glass material in advance and pressure molding between molds high in face precision. CONSTITUTION:The glass material is preliminarily molded by grinding, etc. to remove surface defects, and surface roughness is finished to about <=1/10m. This material is placed on a lower mold 4 in a tightly enclosed chamber 1 and an upper mold 3 is set. A cover 2 is closed, water is allowed to flow through a cooling water pipe 20 and a heater 8 is energized. The inside of the chamber 1 is evacuated to a prescribed vacuum, and then, a valve 16 is opened to introduce an inert gas. When the glass is heated to or above the softening point, an air cylinder 10 is actuated to mold the glass with pressure. This method prevents trouble where the air on the surface of the material is unable to escape by the presence of the large roughness of the surface during the pressure molding and exerts adverse effects on the surface of the optical element. As a result, an optically satisfactory optical element can be obtained.

Title: Thermistor
Inventor: YONEDA YASUNOBU
IPC: H01C7/04
Filed: 1987-09-07
Abstract: PURPOSE:To obtain a thermistor, a B constant and a resistance value R of which can be selected freely, by laminating a plurality of thermistor elements with different thermistor constants (B constants) and resistivity and constituting the thermistor by electrically connecting the thermistor elements in parallel. CONSTITUTION:The whole thermistor is coated with Al2O3 insulating ceramics 23. Each thermistor elements 21, 22 are brought into contact with internal electrodes 25, and the internal electrodes are connected electrically in parallel with external electrodes 26 disposed on both left and right side faces. Diffusion preventive layers 24a, 24b, 24c are formed among the internal electrodes. The diffusion preventive layers are shaped by an Al2O3-ZrO2 group. When B constants of respective element are equalized approximately, resultant resistance R takes a value acquired by connecting each element in parallel, but a resultant B constant is made the same as the B constant of separate element. When the B constants of two elements largely differ, both combined resistance and the B constant approximate values on the element side having a low resistance value. Accordingly, the resistance value and the B constant can be selected from a wide range by choosing the number of laminating of the elements and the B constants of each element.
