Patent number: 11873514Abstract: A method of screening for a substance that acts on a cell mass includes producing a cell mass by three-dimensional culture of primary cancer cells using a tumor tissue, adding a test substance to the cell mass, and evaluating an action of the test substance on the cell mass. The cell mass is produced by culturing cells obtained from the tumor tissue in a medium containing a 5% v/v or less extracellular matrix on a substantially low-adhesive cell culture substrate and producing the cell mass of the primary cancer cells.Type: GrantFiled: December 23, 2022Date of Patent: January 16, 2024Assignee: LSI MEDIENCE CORPORATIONInventors: Hideaki Kakinuma, Yukiko Shimada, Hiroaki Inoue, Takashi Morikawa

Patent number: 11549100Abstract: A method of producing a cell mass by three-dimensional culture of primary cancer cells having proliferative ability and properties of handleability, versatility, and high-throughput performance, in which a tumor tissue is used as a starting material, proliferation of cells such as fibroblasts other than cancer cells is inhibited, and the cell mass includes primary cancer cells as a main component. The object is achieved by providing a method of producing a cell mass by three-dimensional culture of primary cancer cells using a tumor tissue, including: a three-dimensional culture step of culturing cells obtained from the tumor tissue in a medium containing a 5% v/v or less extracellular matrix on a substantially low-adhesive cell culture substrate.Type: GrantFiled: March 15, 2018Date of Patent: January 10, 2023Assignee: LSI MEDIENCE CORPORATIONInventors: Hideaki Kakinuma, Yukiko Shimada, Hiroaki Inoue, Takashi Morikawa

Patent number: 7043043Abstract: There is provided a microphone apparatus with an adjusting mechanism that prevents wind noise generated at a sound absorbing hole from perceptively inputted in the structure having a microphone built-in at the back of a panel with a sound absorbing hole. A sound box is structured between a sound absorbing hole of a panel and a sound perceptible portion of a microphone, and a movable piece that slidably moves in the sound box is formed. A screw rod is annexed to the movable piece, and a disk screwed with the screw rod is restricted and interposed between a tubular portion, serving as an outer frame of the sound box, and a support portion formed at the lower portion. A part of the disk is exposed to the front surface side from a slit of the panel, and the disk is rotated to move the movable piece, whereby changing a resonant frequency of a ventilation space of the sound box and a ventilation cross.Type: GrantFiled: July 29, 2004Date of Patent: May 9, 2006Assignee: Vertex Standard Company, Ltd.Inventor: Hideaki Kakinuma

Patent number: 6804511Abstract: The present invention provides a radio controlling apparatus that performs a change to a vacant channel rapidly to allow smooth control even if an uncontrollable state due to radio interference suddenly occurs. In a radio controlling transmission apparatus of the radio controlling apparatus, a reception section for searching a vacant channel is provided. When a vacant channel is detected, it is stored in memory of the radio controlling transmission apparatus. A transmission section transmits control signals, a selection code, and vacant channel data, the control signals being output by an operation section using a control signal transmission timer and a selection code transmission timer. Using a reception section, a controlled apparatus of the radio controlling apparatus receives signals. If the vacant channel data and the selection code are received, the controlled apparatus stores them in memory of the controlled apparatus.Type: GrantFiled: December 22, 1999Date of Patent: October 12, 2004Assignee: Vertex Standard Co., Ltd.Inventor: Hideaki Kakinuma
