非破壊検査で世界のものづくりを支える
私は非破壊検査装置(マイクロフォーカスX線源(MFX))の製造・開発を担当しています。
MFXの応用先は非破壊検査業界です。スマートフォン等の家電製品や自動車関連部品等に不具合が生じる原因の一つとして、製品内部の電子部品やはんだ付けに問題が発生していることがあり、メーカーでは品質を確保するために、これらに問題がないかどうかを検査しています。製品内部の検査手法として、MFXを用いた透視検査が行われており、非破壊検査には欠かせない存在になっています。
自分の手で世界に発信できるものづくりができることと、あらゆる課題やトラブルに対し試行錯誤を繰り返し目前の問題を解決していくプロセスにやりがいを感じています。また電気電子分野は目覚ましい発展があり、それに追随し、取引先から求められる要求精度が高くなります。それに合わせて自分たちも技術を高めていくために、意見やアイディアを出し合っていくことが楽しいです。今後は中国やインド等の海外に視野を広げていけたらと思っています。
最後まで技術職を貫きたい
現在は、MFX内部に組み込まれている真空管球部の組立工程や、製品の改良・改善が主な業務です。バラバラな材料の状態から、ミクロンオーダーの組立となるので、とても神経を使い作業をしています。MFXは真空管内部に高電圧をかけるので、製品内に微小な突起物（バリ）等があると耐圧不良等の原因になります。バリ取り作業は非常に難しく、業者さんに依頼してもできないケースが多々あります。ですので、こちらでいろいろなツールを組み合わせたり、やり方を検討して所望の特性を実現しています。
将来像として、私はオリジナリティーな発想を生み出せる、新しい時代の職人を目指しています！通常の会社ではエンジニアであっても、ある程度経験や年齢をつむと管理職（マネジメント）になっていくケースがありますが、できれば私は最後まで技術職として現場で働きたいです。
また、Ｘ線関連製品以外にもγ線、α線等を利用できるような新製品開発もしてみたいです。
若手社員でもやりたいことを実現できるのが魅力
当社の魅力は、社員全員が研究者体制であることです。社員一人ひとりの研究に対する意識が高く、皆が前向きな発想を提案する傾向があり、それら1つ1つの意見が尊重され易い環境が整っていることが魅力だと感じます。
例えば、私の部署は手作業が多く単工賃が大きいので、少しでも工数を減らせると年間で大きな経費削減につながるのですが、その「少し」が難しく、悩んでいました。社内にいると考え方が固執してしまうので、チャンスがあれば展示会や学会に参加したいと上司に相談し、積極的に外部の方と交流しました。多くの他社技術者や、新しい業者とコミュニケーションを図ることで、所望のツールを発見し導入した結果、大規模な工数削減を実現できました。
社外の友人と話していて感じることは、1若手社員の意見をこれだけ真剣に聞いてくれる会社は他にないと思います。技術や製品に対して常に量より質の考え方が根付いており、世間から高い信頼性を獲得していることが強みだと感じています。
仕事をする上で大切にしていること
報連相
些細なことでも常に上司や部下と報連相することです。
自分で気付き、考え、行動することも大切です。ですが、周りに迷惑をかけないよう努める余り、推測と自己判断で物事を推し進めてしまうと、結果、取り返しのつかない失敗になることがあるためです。仕事はチームプレーですので、1つの目標に対し、全員が同じ方向を向けるよう、高いアンテナとこまめなコミュニケーションが大切だと思います。
