Abstract: To provide a photoelectric conversion element capable of further improving performance in a photoelectric conversion element using an organic semiconductor material. The photoelectric conversion element includes a first electrode and a second electrode arranged to face each other, and a photoelectric conversion layer 17 provided between the first electrode and the second electrode, in which the photoelectric conversion layer 17 includes a first organic semiconductor material and a second organic semiconductor material, and at least one of the first organic semiconductor material or the second organic semiconductor material is an organic molecule having a HOMO volume fraction of 0.15 or less or a LUMO volume fraction of 0.15 or less.

Abstract: A memory chip unit includes a pad electrode including first and second portions, and a memory cell array. A prober includes a probe card and a movement mechanism. The probe card includes a probe electrode to be in contact with the pad electrode, and a memory controller electrically coupled to the probe electrode and executes reading and writing on the memory cell array. The movement mechanism executes a first operation that brings the probe electrode into contact with the first portion and does not bring the probe electrode into contact with the second portion, and a second operation that does not bring the probe electrode into contact with the first portion and brings the probe electrode into contact with the second portion.

Abstract: When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time at which the kneaded sand starts to flow into the mold is identified based on the pressing force applied to the kneaded sand layer in the kneading sand tank, and a pressing starting position of the pressing member at the pressing start time is identified. As a result, the pressing start time and the pressing starting position of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.

Abstract: First, a supply device supplies a foamed kneaded material into a cylinder. Then, in a state in which an internal space of the cylinder is communicated with a pattern forming space of a mold, the piston disposed in the cylinder is moved toward the foamed kneaded material side while opening a gas release hole formed piercing through the piston. Then, at a timing when the piston has reached an expected position where the piston is expected to be on contacting the foamed kneaded material supplied into the cylinder, the gas release hole is closed by an open-close plug. Then, the foamed kneaded material supplied into the cylinder is pressed toward the pattern forming space side of the mold by moving the piston toward the foamed kneaded material side.

Abstract: A mold forming apparatus includes: a storage tank having in its bottom injection ports capable of being opened and closed, and storing a foamed mixture; a forming mold having runners, corresponding to injection ports, into which the foamed mixture is introduced through storage tank injection ports, and having cavities for forming the introduced foamed mixture into a mold in a predetermined shape; and a pressing device disposed to correspond to the forming mold and pressing the foamed mixture stored in the storage tank to inject the foamed mixture into cavities through runners of the forming mold. A parting surface of the forming mold is formed parallel to a pressing direction of the pressing device, and runners of the forming mold are formed in the parting surface and are tilted with respect to the pressing direction of the pressing device to spread apart from inlets toward outlets guided to the cavities.

Abstract: A sand-mold molding method for producing a molded article obtained by packing foamed sand may include stirring a binder with an aggregate to form foamed sand; forming a cavity via clamping a metallic mold closed; packing the foamed sand into the cavity of the metallic mold and then heating and solidifying the foamed sand; and opening the metallic mold partially to provide a gap in the metallic mold while maintaining the cavity.
