Title: Impact device through hydraulic working
Inventor: AKE TORUSUTEN EKUREFU
IPC: B25D17/24
Filed: 1982-02-09
Abstract: In an hydraulic rock drill there is an hydraulic so called recoil damper that damps the reflected shock waves that propagates from the rock backwardly through the drill stem. The damper comprises a support piston (68) slidably in a cylinder so that a pressure chamber (20) is formed in which the support piston has a piston area. Narrow clearances (75,76) between the support (68) and its cylinder form leak passages and these leak passages are coupled in series with an orifice restrictor (84) to sump. The pressure peaks in the pressure chamber do not reach sealing rings located at the outer portions of the clearances.

IPC: C04B38/00
Filed: 1989-01-26
Abstract: PURPOSE:To obtain microporous material having sufficient mechanical strength and excellent handling properties with keeping excellent heat insulating properties by dispersing fiber of thermoplastic resin into microporous material and mutually fusing fiber with fiber and fiber with ultrafine particle. CONSTITUTION:In a microporous material obtained by molding of ultrafine granular powder, fiber of thermoplastic resin is dispersed and fiber with fiber, and fiber with ultrafine particle are mutually fused to form a microporous material. In said microporous material, volume of the resin component is small in comparison with ultrafine particles of the heat insulating material and almost constructing microporous material as aggregate of ultrafine particle, thus heat insulating property is extremely high. Besides, said resin fiber is bonded by fusion and area of bonded part (adhered area) is extremely, thus increase of heat conduction in solid is small as the resin is a material having relatively small thermal conductivity. Therefore, traditional properties are able to be nearly kept with regard to heat insulating properties and area of the bonded part (adhered area) is extremely small.

Title: Position specifying device
Inventor: HASEGAWA KAZUO
IPC: G21C17/10
Filed: 1990-01-31
Abstract: PURPOSE:To simply and easily replace only a failed magnetic sensor and to prevent a detector body to be destructed due to thermal expansion by fixing a magnetic sensor and a mold case to the detector body after forming them into a module for each magnetic sensor. CONSTITUTION:The magnetic sensor 36 and the mold case 35 are fixed to the body 33 as a module in each sensor 36. When a trouble is generated in a specific sensor 36, a protector tube 44 is detached from the body 33 of the detector 32 and the case 35 is removed, so that only the sensor 36 generating the trouble can be simply and easily replaced. Although the sensor 36 formed into the module is replaced in each case 35, the positioning of the case 35 is unnecessary for the replacement because it is automatically positioned by a positioning fitting part 34. Since the sensor 36 is protected by a mold in the case 35, the sensor 36 can resist vibration, shock and external environment, and because the mold may be used only for the sensor part 36, and the sensor 36 and the case 35 are formed into a module, the quantity of module can be reduced.

Title: Fluid operating type driving device
Inventor: BARUTAA RAISUTO
IPC: F15B15/08
Filed: 1982-02-10
Abstract: Within a cylinder of a double-acting piston-and-cylinder unit there is displaceably arranged a piston. A spatially moveable piston rod in the form of a universal or ball pivot-link chain is connected with the piston. The piston rod is lengthwise guided by tensioning or tie bolts internally of the cylinder, these tensioning bolts clamping towards one another both of the cylinder heads and piercingly extending through the cylinder. Externally of the piston-and-cylinder unit the piston rod is guided within a guide tube which is connected with one of the cylinder heads. This guide tube can possess a random spatial extent. At the piston rod there is attached a coupling element with which there can be coupled the object or the like which is to be moved. This coupling element extends through a longitudinal slot provided in the guide tube. The spatial mobility of the piston rod enables guiding the piston rod externally of the piston-and-cylinder unit in a random direction.

Title: Method for injecting constant amount of liquid into vacuum container and constant pressure valve used therefor
Inventor: IIJIMA HIROSHI
IPC: F16K17/22
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To enable correct injection of liquid into a vacuum container, by injecting a constant amount of liquid fed from a constant amount liquid pump into the vacuum container from a liquid feed pipe incorporating a constant pressure valve having constant pressure function after the inside of the vacuum container has been made vacuum by a vacuum line. SOLUTION: The inside of a vacuum container 2 is pumped to vacuum by driving a vacuum pump 5 and opening a pinch valve 9 which is a cutoff valve while a vacuum valve 4 is open. Though a constant pressure valve 13 of a liquid feed pipe 11 and the inside of a pipe at an upper end of an opening of the vacuum container 2 are vacuum, liquid may not leak from a small hole 12 of a short pipe 7 since an elastomer tube is tightly attached to the short pipe 7 of the constant pressure valve 13 and an outer periphery of the pipe are pressurized by a wire 10 or the like.  When a constant amount liquid pump 8 is driven in this state, if discharging pressure of fed liquid is higher than adhesion of the constant pressure valve 13 to the short pipe 7, the liquid is ejected from the small hole 12 of the short pipe 7 and injected by a constant amount from the liquid feed pipe 11 into the vacuum container 2.
