Title: Pin boss structure of operator
Inventor: OONO HIROMITSU
IPC: F16C33/10
Filed: 1983-02-16
Abstract: PURPOSE:To prevent the breakage of the pin-boss structure of an operator due to the accumulation of local fatigue by forming integrally a finely uneven structure with large numbers of fine apertures on the inner surface of bush or not the periphery of the pin of the pin support of an oil-pressure shovel, etc. CONSTITUTION:A fine uneven structure consisting of fine projections 22 of a trapezoidal cross-section form and fine grooves 23 of an inversed trapezoidal cross-section form is integrally formed in parallel with the axial direction on the periphery of the pin 121 of a pin-boss structure between the arm and boom of an oil-pressure shovel. The fine uneven structure may be formed on the inner surface of the bushes 15 and 17 of bosses 16 and 19, and also may have an axially directed spiral form a knurling form, or a wave form. The presence of the fine uneven structure enables grease to be sufficiently packed and also an elastic deformation to occur according to facial pressure P to be applied, thereby permitting the distribution of the facial pressure to be equalized and breakage to be prevented.

Title: Electrode forming method
Inventor: TAKEUCHI HIROYUKI
IPC: G01N29/26
Filed: 1982-02-17
Abstract: PURPOSE:To prevent the piezoelectric plate of the electron scanning type probe of an ultrasonic diagnostic device from curving even when it is made thin, by coating both surfaces of the piezoelectric plate with electrodes materials so that the materials extend to even side surfaces and then sintering them at a time when forming roundabout electrodes on the piezoelectric plate. CONSTITUTION:PbTiO3 Ceramic formed in a normal baking method is cut in a shape which is 74mm. long, 12mm. wide, and 0.7mm. thick and polished to a 0.27mm. thickness to obtain the piezoelectric plate, on which silver paste is printed so that the pattern of a screen projects by 0.5mm. from one edge where a roundabout part of electrodes is formed; this is left for 10min at about 150 deg.C to vaporize a solvent contained in the silver paste for drying. On the opposite surface, silver paste is printed so that the pattern of a screen projects by 0.5mm. from the other edge where a roundabout part is formed, and the paste is dried. Thus formed electrodes are sintered at 550 deg.C maximum temperature for about one hour. Consequently, the roundabout electrodes are formed as shown in figure without curving the piezoelectric ceramic plate.

Title: Catalyst plug for storage battery
Inventor: NISHIMURA KIYUUZOU
IPC: H01M10/52
Filed: 1979-02-28
Abstract: PURPOSE:To prevent the catalyst plug from explosion and the jar from thermal deformation, deterioration, burning, etc., by providing an enclosing plate between the catalyst container and the catalyst plug exterior. CONSTITUTION:The catalyst plug is formed in such a way that a catalyst container 16 made of porous explosionproof filter is housed in a catalyst plug exterior 13 and a lid 14 with a porous explosion-proof filter 15 is placed on the exterior 13. A gas- impervious heat-resistant enclosing plate 18 is attached vertically to the periphery of the back of the filter 15 so that the enclosing plate 18 encircles the catalyst container 16. This arrangement permits the gas generated in the battery to flow from the passage A to the catalyst 17 which causes reaction to take place. In case gas is generated in large quantities, the unreacted, saturated gas does not go through the gap 19 but goes through the passage B to the filter 15 to be discharged to the atmosphere. Thus, it is possible to prevent the catalyst plug from explosion.

Filed: 1979-02-28
Abstract: PURPOSE: To make it possible to start a gas turbine with less power consumption of a starter and at the same time to heighten the starting ratio of ignition and firing at starting by installing a variable speed control which can control the number of revolutions of the starter optionally.  
     CONSTITUTION: A variable speed control 8 of a system wherein the primary frequency is controlled by an inverter is connected to a starter 5. A setting signal (a) of a number of revolutions is given to the variable speed control 8 from a start control 9. Therefore, the full electric power is not supplied to the starter 5 from the beginning, but an electric power necessary in accordance with a number of revolutions is supplied, and without increasing the number of revolutions evenly any further the number of revolutions of a starter 4 can be controlled. Consequently, the electric power consumed by the starter 4 can be saved and the ignition and firing can be secured in the starting process.

Abstract: PROBLEM TO BE SOLVED: To provide a suit which is esthetically improved so that the breast box pocket is not twisted, even when the line of back bone is a little bent and the shape of the sack part of the pocket cannot be recognized from outside. SOLUTION: A part of the interlining 1 of a suit (jacket) is cut out at the prescribed position corresponding to the pocket in a rectangular form wider than the pocket opening. Then, a patch 4 for breast box pocket is prepared by sewing a cloth 6a so that it may cover all over the cut-out part. Thus, the pocket is put in after the interlining is sewed to the dress fabric and the bag part of the pocket can be let out on the back face of the interlining. Consequently, the pocket is surely held near its opening and the interlining comes in between the dress fabric and the bag part of the pocket to make it impossible to distinguish its shape from outside.

Title: Liquid-in-vibration isolator
Inventor: ORIKAWA MICHIHIRO
IPC: B62D27/04
Filed: 1987-02-04
Abstract: PURPOSE:To absorb vibration ranging over a wide frequency scope, by providing an elastic, lower thick film, which connects an inner tube and an outer tube, an upper, thin film, which forms a liquid chamber between this film and the above-mentioned thick firm and which connects the inner and outer tubes, a partition wall, which partitions the liquid chamber, and a restricted passage, which connects the liquid chambers partitioned. CONSTITUTION:During the low-frequency vibration, the vibration is absorbed by internal friction of a lower, thick film 16, while it is also absorbed by the resistance, which is caused when the fluid in both upper liquid chamber 30A and lower liquid chamber 30B passes through a restricted passage 34. During the high-frequency vibration, although the restricted passage 34 falls into a loaded condition, the pressure in the upper liquid chamber 30A is restricted from rising because an upper, thin film 22 can easily be deformed elastically. As a result, the pressure-rise as a whole can remain almost one half, compared with the case without this contrivance, and the noise insulating characteristics in the high-frequency region can be enhanced.

Abstract: PURPOSE:To facilitate manufacturing, by forming a ZnO layer on a substrate or a conducting substrate, forming, on the ZnO layer, a metal oxide layer forming an electric potential barrier against the ZnO layer, and forming, on the metal oxide layer, both electrodes at a constant interval. CONSTITUTION:On a substrate 11, a ZnO layer 13 is formed, on which a metal oxide layer 14 forming an electric barrier against the ZnO layer is formed.
