JDS Tsugaru. JDS Tsugaru (ARC-481) was a cable laying ship of the Japanese Maritime Self-Defense Force.

Development and design 
The ship was designed by requesting the Ship Design Association, which consists of former Navy engineers, with reference to the  cable laying boat of the Imperial Japanese Navy. Its main task was to lay an underwater hearing monitoring device in the waters around the base and harbor, and due to its characteristics, there were many secrets and it was called a supply repair ship at the beginning of construction.

The structure of the ship was equipped with a sheave for laying submarine cables on the bow, a large cable drum under the bridge, two electric wire storages in the center, and a 5-ton derrick. Other than that, it was equipped with minelaying equipment and anti-submarine warfare equipment including sonar, but this equipment were the result required of the comprehensive design policy and were not very meaningful in operation.

Construction and career 
Tsugaru was laid down on 18 December 1954 and launched on 19 July 1955 at Mitsubishi Heavy Industries Shipyard in Tokyo. She commissioned on 15 December 1955. The vessel transferred to the Yokosuka District Force on 1 September 1957. On 1 September  1961, the 2nd Mine Warfare Force was newly formed and incorporated Tsugaru under direct control.

Equipped with a precision sounding instrument for the deep sea in 1967, a special remodeling was carried out by Tsugaru at the Mitsubishi Heavy Industries Yokohama Shipyard from 10 July 1969 to 20 April 1970. Weapons except the 20 mm gun were removed and new underwater equipment laying equipment was added. Due to this modification, the bow and bridge were greatly changed, and the displacement was more than double that of at the time of construction.

At 0:42 am on 21 August 1972, Tsugaru collided with the small cargo ship Daini Tenjinmaru in the Akashi Strait. The left part of the bow of Tsugaru collided with the center of the starboard side of Daini Tenjinmaru. The cargo ship sank, and two of the three crew members were rescued by Tsugaru, but one went missing. In addition, the damage to Tsugaru was only a dent on the bow.

On 12 January 1977, the laying ship (ARC) was categorized from a mine ship to a special service ship. On 17 March 1980, due to aging, the vessel's type was changed from a laying ship to a special service ship, the ship registration number was changed to ASU-7001, and it was reorganized into the Oceanographic Command.

Tsugaru was removed from the register on 15 March 1990. The following year, in April 1991, equipment was removed and the ship was remodeled into a target ship by installing a heating plate. In April 1992, Tsugaru was circulated to Wakasa Bay, used as a target, and disposed of.

Itoh Emi 9. The Itoh Emi 9 was a two-seat Japanese training biplane built in 1918.

Design and development

After the destruction of Itoh's hangar at Inage Beach by a tidal wave at the end of September 1917 his works and flying school moved to Tsudanuma Beach, otherwise known as Itoh Airfield. The move led a significant increase in student numbers and a new, two seat trainer was needed; until then they had relied on single-seaters. The solution was provided not by Itoh or his employees but by a regular visitor to the airfield, Tomotari Inagaki. He designed a simple and stable two seat trainer around the water-cooled  Hall-Scott V-8 engine taken from the Emi 3. It became known as the Itoh Emi 9.

The Emi 9, typical of its time, had a wooden frame and fabric covering. It was a straightforward two bay biplane, with two  parallel pairs of interplane struts on each side. The wings were rectangular in plan and manufacture was further simplified by the absence of dihedral or stagger.

Its upright V-8 engine was installed in the nose with most of the upper part exposed and its rectangular radiator mounted edge-on just behind the engine on the fuselage port side. Pupil and instructor had separate open cockpits in a fuselage rather similar to that of the Emi 5 and its forebear the Curtiss Jenny. Its tail was also similar to the Jenny's, with a triangular fin, a rudder with a straight leading edge which continued that of the fin and a deep, rounded trailing edge, though the control surfaces had horn balances, the first to be used on a Japanese civil aircraft.

The Emi 9 had a simple, single axle undercarriage with legs on the lower fuselage longerons and trailing drag struts to the fuselage centre line.

Operational history

The Emi 9 served the Itoh school as intended, though details of its history are lacking.

Thiothionyl fluoride. Thiothionyl fluoride is a chemical compound of fluorine and sulfur, with the chemical formula . It is an isomer of disulfur difluoride (difluorodisulfane) .

Preparation 
Thiothionyl fluoride can be obtained from the reaction between disulfur dichloride with potassium fluoride at about 150 °C or with mercury(II) fluoride at 20 °C.

Another possible preparation is by the reaction of nitrogen trifluoride with sulfur.

It also forms from disulfur difluoride when in contact with alkali metal fluorides.

 can also be synthesized with the reaction of potassium fluorosulfite and disulfur dichloride:

Properties 
Thiothionyl fluoride is a colorless gas. At high temperatures and pressures, it decomposes into sulfur tetrafluoride and sulfur.

With hydrogen fluoride, it forms sulfur tetrafluoride and hydrogen sulfide.

It condenses with sulfur difluoride at low temperatures to yield 1,3-difluoro-trisulfane-1,1-difluoride.

Civmec. Civmec Limited is a dual-listed Australian-Singaporean public company involved in the construction, engineering and shipbuilding industries. Headquartered in Perth, Western Australia, it specialises in fabrication and construction for the oil and gas and mining industries and has been involved in a number of significant Australian mining and civil engineering projects and has been selected to build a number of vessels and facilities for the Royal Australian Navy.

History

Civmec was established in 1990, becoming part of the VDM Group in 2006. In 2009, it was sold in a management buyout. It was listed on the Singapore Exchange in 2012, and became a dual-listed company when listed on the Australian Securities Exchange on 22 June 2018.

Civmec's main facilities are in Henderson and Newcastle and it has satellite offices in Gladstone and Singapore. The Henderson headquarters sits on 120,000 square metres of land, and its fabrication plant is the largest in the southern hemisphere. An expansion to the shipbuilding and maintenance facility in 2018 and 2019 resulted in an undercover facility with 53,000 square metres of space, which is the largest in Australia.

Up until 2015, Civmec had largely concentrated on mining and energy-based projects, holding engineering contracts for Shell Australia's Prelude floating liquefied natural gas facility, Chevron Corporation's Gorgon and Wheatstone gas facilities, Inpex's Ichthys gas field and Woodside Petroleum's Persephone project. Around this time, although the company's mining-based contracts continued, the company diversified its work and moved to infrastructure-based projects. Since this time it has undertaken the construction of a number of significant infrastructure projects in Perth as well as commenced military projects.

In November 2015, Civmec agreed terms to purchase Forgacs Marine & Defence. The company saw the purchase as an opportunity to set up a facility on Australia's east coast, and to pursue opportunities to enter into military contracts for submarines, offshore patrol boats and frigates for the Royal Australian Navy (RAN). The purchase, which included the Forgacs Shipyard in Tomago, New South Wales, was completed in February 2016 and resulted in over 150 job losses.

In 2018, Civmec commenced building ten of the Arafura-class offshore patrol vessels for the RAN, and in 2020 commenced building the RAN's new submarine rescue at its Henderson facility, which will include a launch and recovery system, hyperbaric treatment unit, and maintenance training and testing infrastructure with a seven-metre deep pool. This facility is due for completion in February 2021.

Itoh Emi 13. The Itoh Emi 13 was a two seat Japanese trainer, designed for the Itoh flying school and introduced in two versions in 1920 and 1921.

Design and development 

From mid-1919 Otojiro Itoh's flying school at Itoh Airfield at Tsudanuma had relied heavily on the Itoh Emi 9, its only two seat trainer. Its designer, Tomotari Inagaki, had already designed a similar but improved successor, powered by the same Hall-Scott V-8 engine. This, the Emi 13, was built between the summer of 1919 and the following spring.

The Emi 13 was a wooden-framed, fabric covered two bay biplane with pairs of parallel interplane struts. Its wings were rectangular in plan, with overhung ailerons only on the upper wing. Tall, outward-leaning cabane struts braced the wing over the fuselage, where there was a broad trailing edge cut-out to increase the field of view from the rear seat. The lower wings were mounted on the lower fuselage longeron.

Its V-8 engine was nose-mounted with its upper parts exposed and a flat, narrow, rectangular radiator attached vertically just behind it on the port side where the engine cowling joined a flat-sided fuselage. The two separate cockpits of the Emi 5 were replaced by tandem seats in a single open cockpit, with the student under the central wing and the tutor under the trailing edge. This change was made to ease communication between them. Behind them the fuselage had rounded upper decking. The tail was conventional, with the horizontal surfaces mounted on top of the fuselage and the tailplane strut-braced from below.  The fin was small and triangular in profile but carried a large rounded rudder with a prominent horn balance.

The Emi 13 had a single axle undercarriage with large wheels. The axle was rubber-sprung on a cross-braced frame with forward legs and trailing drag struts to the lower fuselage longerons. Its tall tailskid was mounted below the tailplane leading edge.

Operational history

To demonstrate its abilities the Emi 13 took part in a competition sponsored by the Imperial Flying Association held In August 1920 in Tokyo. It gained the fourth prizes for both speed, at  and altitude .

By late 1920 the Hall-Scott engine was reaching the end of its life so Inagaki revised the design to take a  Curtiss OX-5, another water-cooled V-8. Itoh completed this aircraft, referred to as the Emi 13 no.2, in 1921 and it became the principal trainer at the flying school.

Variants

Emi 13 no.1 First example, Hall-Scott powered and flown in 1920.

Emi 13 no.2 Second example, Curtiss powered and flown in 1921.
