Title: Mobile radio channel switching method
Inventor: YOSHIDA HIROMI
IPC: H04Q7/22
Filed: 1984-07-20
Abstract: PURPOSE:To improve the communication quality by providing the first and the second reference values as the reference value of the S/N, on a basis of which channel switching is started, to switch effectively the zone and the channel of a base station in accordance with the first and the second reference values. CONSTITUTION:Plural base stations 1-3 which can communicate with a mobile station 8 by plural channels different from one another are so arranged that zones 4-6 of base stations 1-3 overlap partially, thus constituting a mobile radio channel switching system. When the mobile station 8 is moved across zones 4-6 of base stations 1-3, base stations 1-3 which communicates with the mobile station 8 monitor the S/N and the channel use rates of base stations 1-3. Normally, if the S/N ratio of one base station is lower than the first reference value, it is switched to another adjacent base station to connect the latter base station to the mobile station. If channel use rates of base stations 1-3 are higher than a certain value, the channel of the adjacent base station is switched on a basis of the second reference value higher than the first reference value of the S/N, thereby improving the communication quality.

Title: Manufacture of piezoelectric polymeric sheet with bimorph structure
Inventor: TSUCHIDA TORU
IPC: H01L41/45
Filed: 1986-06-26
Abstract: PURPOSE:To increase a yield by forming conductive films on one side of two films made of a polarized piezoelectric polymeric material and then adhering the side surfaces to each other by an adhesive. CONSTITUTION:Two films 2 and 3 made of a piezoelectric polymeric material are prepared and polarized by a high electric field. Then, conductive coating 6 are deposited on one side of the two polarlized films 2 and 3 by evaporation. Then, these films are bonded together with an adhesive 9 in such a manner that their coated faces are in contact with each other. Thus, by performing the polarization processing in an initial stage, if a dielectric breakdown occurs during the polarization processing, the defective unit is discarded before it is carried to the next process, so that a yield can be improved. Further, since the adhesive is used for adhesion, a flexibility proper to the piezoelectric polymeric material is not damaged.

Title: Spacer for bending pipe and method for bending pipe
Inventor: OHASHI MICHIYO
IPC: B21D9/03
Filed: 1993-05-27
Abstract: PURPOSE:To provide the inexpensive method capable of smoothly bending a pipe and protecting the bent part without flattering or crushing the pipe by using a spacer having an insertion part formed in a row of spherical bodies. CONSTITUTION:When a pipe 3 is bent while the spacer for bending the pipe is inserted into the pipe 3 such as a copper pipe as it is, it can be bent easily and flexibly into shape such as a desired bend or elbow, because the insertion part 1 is constituted of a row of tied spherical bodies 11. On the other hand, since many tied spherical bodies 11 having a diameter nearly the same as the inside diameter of the pipe 3 are arranged in the pipe 3, crushing of the pipe diameter is prevented surely from the inner part. Since the space for bending the pipe has a construction light in weight, excellent in workability, low in cost when it is made of synthetic resin, etc., the spacer can be left inserted into the pipe as it is under construction. When this spacer is left inserted into the pipe as it is, the insertion part 1 serves as a protector to prevent the pipe 3 from being flattened, crushed, etc.
