Inventor: NISHI TOSHIO
IPC: H05K3/30
Filed: 1992-11-17
Abstract: PURPOSE:To provide a soldering method for electronic components which is capable of eliminating defective soldering due to a volumetric decrease accompanied by solder melting when heating a circuit board and soldering the electrode of an electronic component to an electrode portion of the board after temporarily attaching an electronic component to the board with a bond for temporary attaching. CONSTITUTION:A solder precoat portion 8 having a horizontal surface is formed on an electrode portion 2 of a circuit board 1, flux 9 is coated on that surface, a bond 4 for temporary attaching is coated on the upper surface of the board 1, an electronic component 5 is mounted on the board 1, and the base 1 is heated and the solder precoat portion 8 is melted and hardened. By doing this, the electrode 7 of the electronic component 5 can be firmly soldered to the electrode portion 2 of the board 1 because the material of the solder precoat portion 8 is dense and it hardly causes a volumetric decrease after heating and melting.

Title: Member fitting device
Inventor: YAMAMOTO AKIRA
IPC: F16B19/00
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To ensure fitting by forming a part on an extension line of a head as a solid part, providing hollow parts around the solid part, and providing the head with a cutout part at a part opposed to a fitting hole edge part. SOLUTION: A part on an extention line of a shank 3 of a head 5 is formed as a solid part 5a substantially solid, and hollow parts 5b are provided around the solid part 5a. The head 5 is provided with a cutout part 5c opposed to an edge part 1a of a hole 1 of a chassis 2 excluding the peirpheral side. A member 6 is fitted by holding down the head 5, pushing a locking piece 4 into the hole 1 and positioning the edge part 1a between the locking piece 4 and the head 5. Pushingin force is positively transmitted to the shank 3 and locking pieces 4 through the solid part 5a. The head 5 bends because of the hollow parts 5b and cutout part 5c, and pushed-in displacement of the shank 3 and locking piece 4 is large, so that the member 6 is sufficiently pushed in. The member 6 can therefore be fitted positively in a requested fitted state, and the possibility of falling is eliminated.

Title: Cooling method for charged particle beam
Inventor: MIYATA KENJI
IPC: H05H7/00
Filed: 1987-12-07
Abstract: PURPOSE:To enable the accumulation of large current by reducing the lateral spreading of a beam so as to weaken a lateral wake field and also suppressing beam instability resulting in a reduced beam loss. CONSTITUTION:A rectangular parallelopiped cavity 1 is arranged on a particle orbit 10 and a particle beam 2 is made to pass through the cavity 1. A microwave is input from an outside oscillator 100 into the cavity 1 through a connection antenna 101 so that high frequency electromagnet field of TM210 mode is generated into the cavity 1. The resonance frequency of vibration in the electromagnetic field is given by integral multiples of the acceleration frequency of the particle. In this case, strong synchro-betatron resonance is generated in the particle so that the beam lateral spreading is suppressed. Accordingly, the lateral wake field is weakened so that the beam instability is suppressed resulting in a reduced beam loss. Thus, it is possible to carry out the injection, acceleration and accumulation of the particle beam with low energy and large current.
