Abstract: PURPOSE: To obtain a foamable polyvinyl chloride compsn. and to provide a vinyl chloride polymer foamed article.  
     CONSTITUTION: A foamable thermoplastic resin compsn. contains a graft copolymer obtained by grafting an upper layer having α-methylstyrene, an unsaturated nitrile and non-substd. styrene on a base layer consisting of a vinyl chloride polymer and butadiene rubber, a rubber free copolymer having an alkyl methacrylate, a vinyl aromatic and an unsaturated nitrile and a chemical foaming agent. This foamable thermoplastic resin compsn. can be extruded simultaneously with a non-foamed thermoplastic resin skin by a simultaneous extrusion method of the non-foamed thermoplastic resin skin and the foamable thermoplastic resin compsn. This compsn. and the simultaneous extrusion method are useful for producing a coextruded rigid foam structure which is useful in rigid foam applications such as a foamed pipe and a foamed sheet.

IPC: B23H1/10
Filed: 1982-05-21
Abstract: PURPOSE:To facilitate the discharge of chips and decomposition products in a machining solution from machining gaps, by making the liquid level of the machining solution into the depth that a workpiece is almost nearly submerged or so. CONSTITUTION:The depth of a machining solution in electro-discharge machining exerts an influence on the degree of discharging chips and decomposition products in a machining solution out of machining gaps and, what is more, affecting the machining speed and specific consumption in an electrode available. As for the machining solution, in the case where such one mixing polyether-denatured silicone oil with water in specific resistance 3X10<4>OMEGAcm by about 1wt% is used, machining speed comes to the maximum when the depth of a liquid level ranging from the machining part to the level is 2.6mm. while specific consumption in an electrode comes to the minimum when the level depth is in the range of 5-20mm. or so. Like this, the level depth of the machining solution is adjusted to some degree capable almost nearly submerging a workpiece so that not only discharging chips and the like becomes better but also machining performance can be ever so improved.

According, correction can be made by making operation to tilt the reading head to the left. Conversely, when the reading head is tilted to the left, that is, the auxiliary mark is read at a position shown by a segment L, the reading signal becomes as a signal LS. Number of peaks of the reading signal becomes larger in the left than in the right, and it is judged that the head is inclined to the left. Accordingly, correction can be made by making operation to tilt the reading head 4 to the right. Thus, inclination of the reading head can be controlled at high accuracy.

Abstract: PURPOSE:To detect the pressure drop such as leakage of gas easily irrespectively of a change in temp. by interlocking the 1st bellows which has a temp. sensitive part and forms a standard gaseous pressure part and the 2nd bellows which forms a detection gaseous part by means of a transmission shaft. CONSTITUTION:An insulating gas is sealed in a standard gaseous pressure part 13 and a temp. sensing part 15, and an apparatus which measures pressure is connected in a connection port 18b. A transmission shaft 20 is stuck to the bellows 12, 17 of roughly the same diameter in the part 13 and a detection gaseous pressure part 18, respectively, whereby a differential pressure detection part 30 is formed. When the pressure in the part 18 drops on account of leakage of gas or the like, the shaft 20 moves to the right side, and a backing plate 27 turns an L-shaped lever 32. An operating member 35 is then moved downward by a connecting part 34 and the downward movement thereof is indicated by a pressure indicator 37. When the pressure drop execeeds a threshold value, a relay 39 is turned on to trigger an alarm. Since the standard gas is maintained at the same temp. as the gas to be detected by the part 15, the change in the pressure is detected easily irrespectively of temp.

Title: Nozzle and use method thereof
Inventor: FUJIE KENJI
IPC: B05B17/00
Filed: 1989-04-10
Abstract: PURPOSE:To maintain adequate spraying grain sizes and to adjust a spraying angle by providing an energizing means for energizing a core body which is freely movable into and out of a vortex chamber and introduces a liquid for spraying to the vortex chamber. CONSTITUTION:The pressure for force feeding the liquid, such as liquid chemical, from a pump to a nozzle 10 is changed in the case of changing the spraying angle of the nozzle 10. A core body 12 is then subjected to the liquid pressure of a vortex chamber 38 on a front end side and is thereby retreated to the point where the force by this liquid pressure and the energizing force of a compression coil spring 44 balance each other and, therefore, the retreat quantity of the core body 12, i.e. the length of the vortex chamber 38 changes with a change in the liquid pressure of the vortex chamber 38. As a result, the length of the vortex chamber 38 increases and the spraying angle decreases with increase in the liquid pressure in the vortex chamber 38. Since the liquid pressure in the vortex chamber 38 is high as the spraying angle is smaller, the spraying pressure from an injection port 32 of an injection plate 30 increases to accelerate atomization.
