Title: Manufacture of split bearing
Inventor: OKAMOTO TOMIO
IPC: F16C7/02
Filed: 1992-09-17
Abstract: PURPOSE:To prevent the development of faulty rupture positions by forming a rupture projection projected outward out of an estimated rupture and separation site of a bearing, making the estimated rupture and separation site higher in hardness than the other site with the aforesaid projection crushed down, and thereby applying load to the bearing in the direction of rupture and separation. CONSTITUTION:A rupture and separation projection 7 is formed at the estimated rupture and separation site F of a bearing 2 in such a way as to be projected outward. Next, the estimated rupture and separation site F is made higher in hardness than the other site with the aforesaid projection 7 crushed down before the bearing 2 is processed for rupture and separation. Load is then applied to the bearing 2 in the direction of rupture and separation thereafter, so that the bearing 2 is ruptured so as to be separated. This constitution thereby enables the bearing 2 to be stably ruptured at the boundary of the estimated rupture and separation site F acting as a break starting point.

Filed: 1987-10-02
Abstract: PURPOSE: To attain correct article management even when cancellation is made by retrieving a registration pool buffer memory and applying cancellation processing to article sales data when the same article sales data as entered article sales data are in existence. CONSTITUTION: When article data are entered from an entry section and article sales data for registration are generated, the article sales data are sequentially stored in a registration pool buffer memory 9a. On the way of registration to one customer, when the entered article once is cancelled, a designation cancel key 15h is used to state designation cancellation and the entry section is used to enter the article data. Thus, when the same article sales data as generated article sales data are in existence in the registration pool buffer memory 9a, the article sales data are cancelled. When the same data are not in existence, an error is produced and the cancellation is inhibited. Thus, correct article management is attained even when cancellation is caused.
