Abstract: It is an object of the present invention to provide a catalyst having high catalytic activity for oxygen reduction reaction, hydrogen evolution reaction, and the like, particularly a catalyst employing platinum group particles having a small particle diameter. A layered manganese oxide comprising platinum group metal particles between layers. A method for producing a layered manganese oxide comprising platinum group metal particles between layers, or platinum group metal particles, the method comprising introducing a platinum group complex between layers of a layered manganese oxide and reducing the introduced platinum group complex by electrolysis, wherein a potential applied to the platinum group complex is changed in a positive direction and a negative direction.

Abstract: To assemble a positioning member, which is to come into abutment with a liquid ejection apparatus, to a liquid ejection member, the present disclosure has adjustment parts for adjusting positions of the positioning member and the liquid ejection member and securing parts for coupling and securing the positioning member and the liquid ejection member and thereby couples and secures the positioning member and the liquid ejection member. Thus, the positions of ejection ports of the liquid ejection head set in the liquid ejection apparatus and reference positions can be positioned with high accuracy.

Abstract: An instruction output device facilitates coping with risks on security by including a first acquisition unit for acquiring, in response to input of risk information indicating contents of a risk related to security of an information processing terminal, one or more instructions corresponding to the risk information; a second acquisition unit for acquiring, for each of the instructions acquired by the first acquisition unit, a message indicating contents of the instruction corresponding to a security-related skill level of a user of the information processing terminal; and an output unit for outputting the message acquired by the second acquisition unit to the user.

Abstract: A speech transmission compensation apparatus that assists discrimination of speech heard by a user, includes: one or more computers each including a memory and a processor configured to: accept input of a speech signal, detect a specific type of sound in the speech signal, analyze an acoustic characteristic of the specific type of sound in the speech signal and output the acoustic characteristic; accept input of the acoustic characteristic being output by the memory and the processor, generate a vibration signal of a duration corresponding to the acoustic characteristic and output the vibration signal; and accept input of the vibration signal being output by the memory and the processor and provide the user with vibration for the duration on the basis of the vibration signal.
