We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 74>. Bobin-kun has been pointed out many times in the past for "not having product labels." It's unfortunate, but once materials (products) have reached that state, they cannot return to the front line (active duty).

Since only those items are there, there is no chance of mistakenly taking something out, and there is no need to search around for necessary items. The "products" have labels attached, making it clear what they are. If this is not done, you will be strictly reprimanded by the "2S Patrol Team," just like Bobin-kun, who is wandering around the factory.

"We are the 2S Patrol Team" At Sakai Nobuaki, we regularly inspect the 2S conditions within the factory across departments and sections, providing feedback and improvement recommendations. Excuses may arise from each area, but 2S activities are necessary for the comfortable operation of the company. While we aim to establish daily 2S practices, the work is done within a limited timeframe, and there are moments when things appear chaotic.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakae, <Episode 71>. At Sakae Nobu, we are engaged in "manufacturing" with the factory operating at night, but the amount of work and the number of employees involved are significantly lower compared to the daytime. Therefore, if you walk around the factory, you will find only a few people working. Only a part of the manufacturing department's drawing section and the annealing (heat treatment) section are operational, while the shipping inspection section, die section, delivery section, quality assurance room, sales department, purchasing department, accounting department, etc., are all on break.

While automation can be implemented for tasks like the automatic attachment and detachment of bobbins, as well as rewinding and splitting, I believe it is very difficult to achieve full automation and unmanned operation for all processes. To automate and operate without human intervention, robots would need to perform these tasks. However, depending on the nature of the work, some processes may require a very high capital investment if done by humans.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 57>. The tapered bobbin is a bobbin used for floor placement. The tapered bobbin allows you to pull the wire upwards without rotating the bobbin itself, keeping it on the floor. In the case of floor placement, since the wire is pulled upwards, it is easily affected by wire memory. If the diameter of the wire memory is small, it can easily create points on the wire that resemble knots (kinks). Therefore, when pulling the wire, we apply resistance using whiskers to prevent this from happening.

For example, wire materials used for ropes (twisted wires) are desired to have ± (plus/minus) tolerances or + (plus) tolerances. This is because a certain breaking strength is required for ropes (twisted wires). If each individual wire that makes up the rope (twisted wire) becomes minus tolerance (thinner), the breaking strength of each individual wire decreases. As a result, the breaking strength of the finished rope (twisted wire) becomes lower, falling below the standard values for ropes (twisted wires).

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" <Episode 31> by Nobu Sakai. Hard drawn wire is characterized by high tensile strength (breaking strength), low elongation, and elastic (spring-like) properties. It is used in processing and applications that are suitable for these characteristics. In the case of wire materials, the typical applications are "springs" and "twisted wire (ropes)." "Springs" are used as single wires (one piece), while "twisted wire (ropes)" are made by twisting multiple wire materials together.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 30>. Not only stainless steel wire but also metal wire can be broadly classified into two categories based on "finish." There are two types: soft wire and hard wire. This is a significant difference, so naturally, when used as materials, the choice will depend on which material (property) is suitable for the intended use and processing.
