Title: Shell of chair
Inventor: MURAKAMI TOMOKAZU
IPC: A47C7/40
Filed: 1994-04-05
Abstract: PURPOSE:To develop rigidity sufficient to hold a sitting posture in a state having pliability by forming an upper half part into a structure having flexibility and providing a reinforcing member to the position connecting the attaching part of a lower half part. CONSTITUTION:When load is applied to the shell 5 of a chair, the central part 5n of the central part UA of the shell 5 is bent rearwardly. The stress generated in the central part 5n by the load reaches an upper edge reinforcing rib 5c and an inclined rib 5h. The stress reaching the rib 5f is absorbed by a lower edge reinforcing rib 5e through the rib 5f and the reinforcing rib 51 of an attaching part 5c and the stress reaching the rib 5h is transmitted to the respective edge reinforcing ribs by the rib 5h. In this case, even if there is no rib structure in the central part 5n, the rigidity of the whole of the shell 5 does not become insufficient and deformation such that the lower half part LA of the shell 5, especially, the lower edge 5a thereof protrudes toward seat is certainly suppressed and a sitting posture can be sufficiently held in such a state that a backrest (b) is slightly bent.

Abstract: PURPOSE:To prevent explosion and breakage with steam pressure caused by water leakage, etc., in apparatus from occurring by making a door of a melting chamber in the apparatus for manufacturing flake by rapidly cooling molten metal with a rotary cooling drum the special structure of hinge type one side opening. CONSTITUTION:In the molten metal flake manufacturing apparatus composing of a melting chamber 32 and a flaking chamber 33, water is leaked from the cooling drum 47 in the appara tus or the other water cooling apparatus, and the pressure in the apparatus is abnormally increased with generation of a large quantity of steam by the molten metal 44, and it happens that the apparatus is explosded and broken. In order to prevent this, the structure of the door 46 in the melting chamber 32 is formed by a door body 2 opening/closing to the one side opening type with the hinge 3 and at the other end part, the door body 2 is fitted to a window part 1 with hooking mechanism 4 of handle fastening, etc., and also a lock arm 13 pushing a connecting pin 15 into a long hole 14 fitted to the door body 2. When the steam pressure in the apparatus abnormally rises, the lock arm 13 is shifted along the long hole 14, and gap 17 is developed between the door body 2 and the window part 1 and as the high pressure steam 18 in the apparatus is discharged, the door 46 in the melting chamber is blown off to prevent the explosion from occurring.

Abstract: PURPOSE:To prevent the contamination on a substrate by covering the path of an ion beam with a specified material. CONSTITUTION:The surface or the member itself of each of the members, which are provided on the ion beam path 1a inside an ion implantation device 1, that is, a lead slit 4, a lead electrode 3, a analysis slit 3, a liner 8, an accelerating electrode 10, a focusing lens 11, a slit 18, a substrate holder 15, and a beam stopper 14 are constituted of highly pure silicon. The substance which is created when the surface of these members are sputtered with ion beams Ia becomes the substance the same in composition as the substrate 20, and the pollution of the substrate can be avoided. Moreover, the content of the elements other than silicon contained in this substance is extremely small, so the contamination on the substrate 20 by the impurities such as heavy metal, etc., can also be avoided. This way, the contamination on the substrate by the sputtering of the ion implantation device can be avoided effectively, and the defects induced in the substrate in ion implantation can be restored efficiently by the later heat treatment, so the deterioration of the electric properties of the element resulting from these defects can be prevented, and the yield rate of the semiconductor integrated circuit can be improved.

Filed: 1991-03-29
Abstract: PURPOSE:To provide a method of assembling an oscillator by which piezoelectric elements can be stacked integrally without causing phase shift while a constant force is being applied to them. CONSTITUTION:Piezoelectric elements 1a, 1b, 2a, 2b, 3a, 3b, 11 and electrodes 4, 5, 6, 7 are stacked between front and rear metal blocks 8, 9 and a semi- assembled oscillator is set vertically before a tightening bolt 10 is inserted while the lower end face of a lower metal block is mounted on a fixed table 20.

Title: Ionization type smoke detector
Inventor: OKUDA YOSHIHIKO
IPC: G08B17/113
Filed: 1978-06-05
Abstract: PURPOSE: To prevent highly efficient ionization and external release of radioactivity by inserting net form electrodes between two sets of outer electrodes thereby ionizing air.  
     CONSTITUTION: If outer electrodes 1, 2 and second net form electrode 5 are connected to the anode of a DC power source 7 and first, third net form electrodes 4, 6 to the cathode, then the air near the electrodes 1 thru 6 is inoized highly efficiently by the radiations radiated by the radiation source 3 of the electrode 1 without making the power source 7 high in voltage causing ion current to flow in a detecting circuit 8. In addition, the exteral emission of radioactivity is prevented by this electrode constitution. Hence, if ions deposit on aerosol owing to smoke, the current value of the circuit 8 changes, thus detection of the presence of smoke is accomplished highly efficiently without releasing radioactivity to the outside.
