摘要： An electrostatic screen printer includes: an electrically conductive screen arranged in non-contact with a printing medium; sponges for rubbing a powder into the screen; and a direct current power source for applying a voltage to the printing medium and the powder, wherein the powder rubbed into the screen is adhered to the printing medium by electrostatic induction. The electrostatic screen printer includes a rotation mechanism for rotating the sponges, a parent revolution mechanism for parent revolution of the sponges, and a child revolution mechanism for child revolution of the sponges. The revolution speed ratio of the child revolution to the parent revolution may preferably be 4.0 or greater, a scraper is provided on the parent revolution mechanism so as to be interlocked with the revolution of the sponges, and the scraper is arranged so as to scrape the powder on the screen toward an axis of the parent revolution

摘要： Provided is a method for producing an all-solid-state battery, which is capable of preventing the occurrence of a short circuit or a charge abnormality due to the formation of a dendrite even in cases where the pressing force is decreased. In the method for producing an all-solid-state battery, a solid electrolyte layer is arranged between a positive electrode layer and a negative electrode layer and current collectors are connected to the positive electrode layer and the negative electrode layer, respectively. This method for producing an all-solid-state battery is characterized by comprising: a step for forming at least one powder film for constituting the positive electrode layer, the negative electrode layer and/or the solid electrolyte layer, and a step for pressing a surface of the powder film by a pressing body consisting of an elastic body.

摘要： There is provided an electrostatic film formation device including a powder feeder feeding powder, a substrate on which a powder film is to be formed from the powder, and a DC power supply applying voltage to the powder feeder and the substrate. The DC power supply applies the voltage to draw the powder from the powder feeder to the substrate with electrostatic force. The electrostatic film formation device further includes a masking member disposed between the powder feeder and the substrate. The masking member is formed with a passing port allowing the powder to pass from the powder feeder to the substrate. The masking member is disposed in the state where the masking member is not in contact with the powder film to be formed.

摘要： A pressurizing suction-attachment table is provided with a porous body having a suction-attachment surface on which an object can be placed, an elastic member directly provided to the porous body, and a frame body supporting the porous body with the elastic member therebetween. An aspiration space is formed between the porous body and the frame body. The pressurizing suction-attachment table is provided with an aspirator capable of aspirating the aspiration space to cause the object to be suction-attached to the suction-attachment surface. The porous body includes an opposite surface positioned on a side opposite to the suction-attachment surface. The frame body includes a receiving surface for receiving the opposite surface when the elastic member is elastically deformed due to pressurization of the object placed on the suction-attachment surface onto the suction-attachment surface. The pressurizing suction-attachment table is configured such that, when the opposite surface is received by the receiving surface, the porous body applies a uniform reactive force to the object being pressurized.

摘要： An all-solid-state secondary battery includes a first electrode body having a first current collector and a first electrode layer, a second electrode body having a second current collector and a second electrode layer, and a solid-electrolyte layer disposed between the electrode layers. On the edge of the first current collector, a first insulating member is provided via a first bonding layer. On the edge of the second current collector, a second insulating member is provided via a second bonding layer. The side end face of the solid-electrolyte layer is disposed outside at least one of the side end faces of the first electrode layer and the second electrode layer. The bonding layers are separated from the respective inner side ends of the insulating members such that each of the current collectors has a deformable distortion buffering area.
