Abstract: A flow sensor includes a detector provided on a side surface of a body formed in a tubular shape. First and second passages formed in the interior of the body communicate with an introduction passage of the detector via first and second sensor passages. The first and second sensor passages penetrate through and open respectively on first and second projections, which project at predetermined heights from an inner circumferential surface of the body, communicating with the first and second passages. A fluid, which flows from the first passage and into the first sensor passage, after being guided to the introduction passage and the flow rate thereof detected by a detector, flows through the second sensor passage and into the second passage.

Abstract: The present invention aims at avoiding a hung-up in the case where a command is sent from a controller within a printer but there is no response to the command from the unit side within the printer, due to a faulty communication or the like, and also in the case where a noise is introduced in the communication data. In the present invention, based on a command sent to the unit side, a data amount of a response from the unit side to this command is predicted, and also a threshold value of response time is provided (S21), which is the time when from the command is sent until the time when the response is received. After the command is sent (S23) until the threshold value of the response time elapses, the receive data is sequentially stored in the receive buffer up to when the data amount from the unit side reaches the predicted data amount (S28, 32, 34).

Abstract: A composite rubber body is formed by embedding steel cords in rubber and vulcanization-building them. In this case, each of the steel cords is a single steel filament wire or plural twisted steel filament wires obtained by drawing of a wire rod of high carbon steel having a given composition. The filament wires satisfy given relationships between filament diameter and tensile strength before and after the vulcanization and have a retention of loop strength of not less than 55%.
