Variable output type allows for voltage suitable for various applications! It can be used for a wide range of purposes.

The "GT Series" is a separated type of DC high voltage power supply consisting of a control unit (controller) and a high voltage generation unit (cartridge). The control unit and the high voltage generation unit are connected by a control cable, allowing for ON/OFF switching of high voltage application at a distance corresponding to the length of the control cable. (Standard length of control cable: 5m) Since the high voltage generation cartridge can be directly connected to the electrodes of electrostatic devices, conventional high voltage cables are unnecessary. 【Features】 ■ Output voltage: 0–100kV ■ Variable output function ■ Maximum output current: 80μA ■ Long lifespan and high reliability ■ Versatile applications beyond charging and discharging *For more details, please refer to the PDF document or feel free to contact us. *We also accept contract manufacturing of high voltage power supplies.

[Instructor] Kikaku Corporation, Nomura Research Institute, Consulting Division Senior Principal, Patent Attorney Rikiichi Hayashi [Key Lecture Content] In today's manufacturing industries, including electronics, machinery, chemicals, semiconductors, batteries, pharmaceuticals, telecommunications, automobiles, food, steel, cement, convenience stores, and content IP, the intensification of global competition and the rise of emerging companies leading to commoditization are accelerating. It is becoming increasingly difficult to secure sustainable profits with traditional exclusive intellectual property strategies alone. In this seminar, we will systematize the management model practiced by winners as the "IPX Management Strategy Model." By redefining and clarifying the functions of Open IP (customer-attracting IP) in addition to traditional Closed IP (revenue-generating IP), we will explain specific methods for management transformation that create asymmetric advantages (business disruption power) that overwhelm competitors. We will share practical approaches that achieve an operating profit margin of over 15% and a PBR of 2-3 times.

We will hold the 29th University-Originated Seed Matching Seminar. We will introduce the latest technologies from Kyoto University. We hope you will join us. 【▼Details here (Free participation, online)】 https://www.tlo-kyoto.co.jp/event/202511191448.html ━━━━━━━━━━━━━━━━━━━━ ◯ Date and Time: December 18, 2025 (Thursday) 13:30–15:00 ◯ Application Deadline: December 12, 2025 (Friday) ◯ Format: Online, Free ━━━━━━━━━━━━━━━━━━━━ ▼ Program Around 13:30–14:00: “Automatic Detection System for Muscle Activation Intervals for Home Monitoring of Sleep Disruption Factors” Lecturer Kana Eguchi, Graduate School of Informatics, Kyoto University Around 14:00–14:30: “Quantitative Evaluation of Antibody Drug Stability Against Fluid Stress” Professor Kenji Sugase, Graduate School of Agriculture, Kyoto University Around 14:30–15:00: “High-Throughput, Low-Cost Comprehensive Transcriptome Analysis Enabled by Nearly Random Index (NRI) Method” Professor Yasuhiro Murakawa, Graduate School of Medicine / ASHBi, Kyoto University
