A reciprocating saw --also known as a "recip saw" or "hognose saw"--was invented by the Milwaukee Electric Tool Corporation in the s and branded Sawzall, is used mainly for demolition. Tokyo, Japan: Kodansha International, Ltd. Advanced Search. Wood flour can be subject to japanese hand saw types journal explosions if not cared for and disposed of properly.

Every soldier was issued one, whether or not he used a rifle. The Japanese bayonet was never shortened during the Pacific conflict, while, for example, the British abandoned their sword bayonet. The bayonet remained 20 inches in length until The design and quality of the bayonet deteriorated from onward. Although its official designation was Type 30, there were many variations in the design principally due to lower manufacturing costs.

The infantryman also referred to his bayonet as his gonbo-ken or burdock sword due to its similar appearance to the leaf architecture of the plant of that name.

Those leaves can grow up to mm in size, and their tapering appearance is similar to a sword. Japanese infantrymen were given frequent and rigorous instruction in the art of using the bayonet on an Arisaka rifle.

The bayonet was fixed using a crossguard loop and a lock stud, both located on the pommel of the Type To prevent reflection, blades were frequently covered with mud before combat operations, although many American veterans of the Pacific war reported seeing the flashing of the bayonet steel during a banzai charge.

Unfortunately, the brutality and savagery of some Japanese soldiers was evident when enemy wounded or prisoners were tied to trees for bayonet practice. This atrocity was verified in China and Malaya. It has been estimated that during approximately 40 years of production over 10 million Arisaka rifles were manufactured. A petal chrysanthemum on the barrel indicated that the rifle was the property of the emperor. If a rifle were to be sold, demilled, or surrendered, the chrysanthemum was usually ground off.

Both types of Arisaka rifles made before and during the war were of good quality. Since sufficient numbers of the Type 99 rifle were never produced, the Type 38 remained in service until I have a 6. Why is this?? Myron Mokris.

In the annals of military history magazines, this is one of those moments. It changed the world more than any other single event in history.

But of larger concern are substances such as lignins and fatty acids that protect trees from predators while they are alive, but can leach into water and poison wildlife. Those types of things remain in the tree and, as the tree decays, they slowly are broken down.

But when sawyers are processing a large volume of wood and large concentrations of these materials permeate into the runoff, the toxicity they cause is harmful to a broad range of organisms. To lower the concentration of airborne dust concentrations during woodworking, dust extraction systems are used.

These can be divided into two types. The first are local exhaust ventilation systems, the second are room ventilation systems.

Use of personal respirators , a form of personal protective equipment , can also isolate workers from dust. These rely on air pulled with a suction force through piping systems from the point of dust formation to a waste disposal unit.

LEV systems consist of four elements: dust hoods at the point of dust formation, ventilation ducts, an air cleaning device waste separator or dust collector and an air moving device a fan, otherwise known as an impeller.

The impeller is usually built into, or placed close to, the waste disposal unit, or dust collector. Guidelines of performance for woodworking LEV systems exist, and these tie into occupational air quality regulations that exist in many countries. This high velocity is accompanied by airflows often less than 0.

Festool is one manufacturer of portable power tools using LVHV ventilation integrated into the tool design. If suitably designed, general ventilation can also be used as a control of airborne dust. General ventilation can often help reduce skin and clothing contamination, and dust deposition on surfaces.

Within industry, many countries have air quality regulations. This is to help ensure that wood dust is extracted to a level that ensures specified maximum allowable residual airborne dust concentrations and worker exposure levels.
