Abstract: The present invention relates to a jig for vitrification cryopreservation of cell or tissue, having a metallic support, and a vitrification solution absorber including an adhesion layer and a vitrification solution-absorbing layer on the metallic support in the order from the side closer to the metallic support.

Abstract: Provided is a device for vitrification-based cryopreservation which enables easy and reliable vitrification freezing of cells or tissues. The device of the present invention for cell or tissue cryopreservation by vitrification has a porous structure made of a material having a refractive index of 1.45 or less as a vitrification solution absorber.

Abstract: The housing of the female-type electrical connector has a mating area used for mating with the above-mentioned male-type electrical connector formed within the terminal array range of the blades and outside the placement range of the blades in the through-thickness direction of the blades and, within the mating area, has guided portions which are formed as spaces that receive the guiding portions of the male-type electrical connector, and block portions which enter the block portion receiving spaces of the male-type electrical connector and support the blades of the male-type electrical connector in the above-mentioned through-thickness direction, with said block portions being formed in the same region as the guided portions in the above-mentioned through-thickness direction.

Abstract: In an electrical connector for circuit boards or blades, a holding portion formed in a housing has, for each blade, holding grooves that hold the front portions of the blades, and at least one of the above-mentioned multiple blades is fixedly secured in place within one of the corresponding holding grooves while the rest of the blades are made movable through a small gap within the respective corresponding holding grooves. With this arrangement, the fixed blade may be used as a reference while the other blades are free to move slightly during a mating step. In addition, such blade securement may be of use of resilient latches (19) positioned at both ends of each blade (20). At engagement to a mating connector, housing portion (75) of the housing is to provide support for ends of the blades (20).
