Title: Clutch mechanism engaging at fixed position
Inventor: MIYAGI YOSHIO
IPC: F16D21/00
Filed: 1986-07-13
Abstract: PURPOSE:To enable a follower shaft to be prevented from being suddenly accelerated by installing a clutch which controls the transmission of power from an output shaft to said follower shaft so as to put another clutch in engagement when the rotating speed of said follower shaft is the same as that of said output shaft. CONSTITUTION:In order to make a prime mover shaft 1 and a follower shaft 6 to engage with each other at a fixed position and to run continuously from the state in which said prime mover shaft 1 is continuously running while said follower shaft 6 is at a standstill, a clutch 5 which controls the power transmission of an output shaft 3 and said follower shaft 6 is activated and put in engagement just when said output shaft 3 comes to a standstill during its intermittent rotation or reciprocating rocking motion. Said output shaft 3 of a cam mechanism 7 then begins to rotate by being driven by a cam 71 fixed on an input shaft 2. Since a clutch 4 is activated and put in engagement, during the time in which said prime mover shaft 1, said follower shaft 6, and said output shaft 3 are running at the same speed, the sudden acceleration of said follower shaft 6 can be thus avoided.

Title: Method for soldering thin flat ic
Inventor: KOMATSU SHIGEMITSU
IPC: H05K3/34
Filed: 1987-07-02
Abstract: PURPOSE:To prevent a sudden thermal shock to a thin flat IC at the time of passing through a solder bath by attaching and soldering a cover surrounding the flat IC at the time of flow soldering. CONSTITUTION:A thin flat IC is capped with a metallic cover 4 surrounding the IC, and the metallic cover and the package part of the thin flat IC are not in contact with each other. Therefore, when passing through a solder bath, since the metallic cover and the package are not in contact with each other, a thermal insulating layer by air is caused in that part. For this, the heat of a solder 6 is not directly transmitted to the thin flat IC. Also, the heat shock given to the thin flat IC is greatly reduced, so that no crack occurs in the thin flat IC.

Abstract: PURPOSE:To achieve a stable fluidity of the negative agent of an alkaline battery by preparing the negative agent by adding zinc oxide powder to the amalgamation product of zinc powder containing at least 90pts.wt. of spherical zinc particles of 100-200 mesh. CONSTITUTION:Zinc powder containing at least 90wt% of spherical zinc particles of 100-200 mesh is suspended in a warm alkaline water. Next, the thus prepared suspension is combined with 10pts.wt. (to 100pts.wt. of the above zinc powder) of mercury to perform amalgamation before the resulting amalgamated matter is subjected to vacuum drying. Next, after 100pts.wt. of amalgamated zinc powder is mixed with 0.5pts.wt. of zinc oxide powder with 8mum grain diameter to make a negative agent, this is used to form a negative electrode 7. After that, the thus formed negative electrode 7 is combined with a positive electrode 1, a separator 3 and an electrolyte-absorbing body 4, thereby constituting a button- type silver oxide battery. As a result, the contact among the particles of the zinc powder is effectively suppressed to prevent their cohesion. Consequently, the discharge characteristic of the battery is enhanced through the improvement of the fluidity of the negative agent.
