According to one embodiment, a sample inspection apparatus includes a photodetection circuitry, an image sensor, processing circuitry, and an output interface. The photodetection circuitry has light incident on an optical waveguide in an inspection container and detects the light having propagated within the optical waveguide and coming out of the optical waveguide. The image sensor acquires an image signal for the optical waveguide, using scattered light originated from the light propagating within the optical waveguide. The processing circuitry acquires one or more inspection index values based on at least one of an output of the photodetection circuitry or an output of the image sensor. The output interface outputs a result of processing by the processing circuitry.

A pressure gauge has an indicator needle and a scale plate. A preset pressure indicating member extending along a pressure scale in a circular arc pattern is slidably attached to a front wall of a case, and provided with a first display section. An opaque shield portion provided with a second display section at one end thereof is provided to a transparent cover rotatably attached to the front wall. The transparent cover drives the preset pressure indicating member to set a preset pressure range between the first display section and the second display section which is observable from the outside through the transparent cover.

An internal pilot type pressure regulatorreduces a pressure of compressed air supplied to a primary portand causes it to flow out to a secondary port. The pressure of air which flows into the secondary portis set by rotating a handleso as to adjust a spring force which is added to a pilot diaphragm. When a bonnet, into which the pilot diaphragmand a pressure regulating memberare incorporated, is inserted in a pressure regulating adapterand then rotated, an outward projecting portionabuts on an inward projecting portionand is mounted. When a lock memberis inserted between the outward projecting portionand the inward projecting portion, the pressure regulating adapteris locked.

A pilot type pressure regulator has: a primary port to which air is supplied from the outside; and a secondary port discharging air regulated by a main valve body provided to a main valve shaft. A main valve diaphragm abutting on an abutting end surface of the main valve shaft partitions an inner space into a secondary pressure chamber communicating with the secondary port and a pilot pressure chamber to which pilot pressure is supplied. This pressure regulator has an exhaust mechanism exhausting air from the secondary pressure chamber to the outside when pressure of the secondary port exceeds a set value. In the exhaust mechanism, a stopper holding a sealing material in a guide hole is inserted from the side close to a main valve hole, that is, an inner end portion.

A processor transmits, to a communication control module, at least one write request packet with which at least one data block element configuring a data block is respectively associated, and updates a first counter to a value corresponding to the number of the transmitted write request packets. The communication control module writes a data block element associated with the write request packet to a cache memory, updates a third counter to a value corresponding to the number of the transmitted data block elements, and reflects the third counter to a second counter. The processor determines that the data block is written to the cache memory when the second counter reaches the first counter after all write request packets are transmitted.
