Title: Reduced pressure casting method using lost form pattern
Inventor: YAMASHITA TSUNEO
IPC: B22D18/06
Filed: 1987-05-14
Abstract: PURPOSE:To execute the precise casting for a short time by coating the specific facing agent on surface of a lost form pattern, investing it in an inner part of sand in a flask, expending the pattern by blowing hot blast under reducing pressure to form hollow part and pouring molten metal under reducing pressure. CONSTITUTION:The facing agent 2 having permeability and suitable strength at the time of pouring molten metal is coated on the surface of the lost form pattern 1 of polyurethane resin, etc., and it is invested in the inner part of the sand 4 in the flask 3. next, the pressure in the flask 3 is reduced with wire gauze pipe 8 for reducing pressure and hot blast having high temp. is blown from upper part above a sprue cup 11 and a feeder head cup 12, to decompose and expend the pattern 1. Then, as the decomposed material exhausts outside of the pipe 8 through the sand 4, only the facing agent 2 is remained in the inner part of the sand 4, and the part where the pattern 1 was set, becomes the hollow part 31. The molten metal is poured into the hollow part 13 under condition as reducing pressure in the flash 4. By this method, the precise casting is executed in a short time without developing the carburizing phenomenon, deterioration of the shape, etc.

Title: Air conditioner
Inventor: IZUMI YOSHIKI
IPC: F24F1/0063
Filed: 1981-07-27
Abstract: PURPOSE:To reduce a change in performance of a blower and to decrease the production of a blow noise, by a method wherein, in an exclusive cooling type, or a cooling/heating type indoor type air conditioner, a partition is located in the same surface as that of a connecting part of a wind direction changing blade. CONSTITUTION:With an one-through type runner 7 turned, air sucked through a  suction port 1a is heat-exchanged during the passage of a heat exchange 5, and  is divided into two currents by a partition 8a to pass a duplex wind direction changing blade 2 to be blown out through an outlet 1b. The partition 8a, the connecting part of the wind direction changing blade 2, and the partition of the runner 7 are positioned in the same surface, and thereby, an air path is approximately divided into two parts. Thus, even if a blow performance of a space corresponding to the length of the one blade changes resulting from a change in the angle of the one-sided wind direction changing blade 2 to increase a noise, no change is produced in the other blade, which results in reducing a change in the blow performance and a noise on the whole.

Abstract: PURPOSE:To disperse the load imposed on a back door as well as to prevent a closed section of both upper and lower rails from opening, by constituting a hinge reinforce of the back door with a hinge receiving base seat part, a horizontal part being flat down at both sides of the former, and a part being erected vertically upward. CONSTITUTION:A hinge reinforce 3 reinforcing a door hinge 2 of a back door 1 is constituted of a hinge receiving base seat part 10, a lower rail weld 11 and an upper rail weld 12. The weld 11 is formed into leglike form being flat down at both sides of the base seat part 10, while the weld 12 is erected vertically upward at the outside of the weld 11 and the base seat part 10. And, the weld 11 is joined to a lower rail 4 and the weld 12 is to an upper rail 5 by weilding, respectively. In consequence, the load imposed on the back door 1 is dispersed on the lower rail 4 and the upper rail 5, reducing the burden, so that plate thickness increment for prevention of the possible mouth opening of a closed section of both these rails 4 and 5 is no longer required, thus weight increment is checked and manufacturing cost is reducible.

Title: Manufacture of sealed lead-acid battery
Inventor: NOBEYAMA KOICHI
IPC: H01M10/12
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To enhance effect on formation charging and prevent the overflow of an electrolyte from a battery container by applying ultrasonic vibration to a lead-acid battery via water. SOLUTION: A sealed lead-acid battery is immersed by about 2/3 of the height of a battery container in a water bath, and then is charged for container formation in that state. During the container formation, an ultrasonic waves having a frequency of 50 kHz is oscillated for 10 minutes to give vibration to the battery. As a result, gas trapped between an electrode and a separator in the container formation tends to be released easily, the diffusion of electrolyte is accelerated, and the container formation is efficiently conducted. Preferably, when ultrasonic vibration is applied after charge exceeds 490% of the theoretical charging capacity, the formation charging efficiency is sharply enhanced. In order to enhance the formation charging efficiency, applying of ultrasonic vibration for 5 minutes or more is necessary.  Howeres, if it exceeds 40 minutes, an active material comes off from a grid and there is a possibility of life time becoming shorten, so that a time period within 30 minutes is preferable.

Title: Portable tool for rotary hammer* etc*
Inventor: FURANKU EFU SHINPUSON
IPC: B25D11/06
Filed: 1980-08-29
Abstract: There is disclosed a combination rotary and percussive portable tool driven by an electric motor. The percussive tool includes a reciprocating cylinder having embodied therein a reciprocatable piston striker. The cylinder is mounted in a guide tube which is spring loaded by a spring positioned between an internal wall in the housing and a cap removably mounted over an opening of the housing. The opening provides access to the housing in order to remove the guide tube and spring. With the guide tube resiliently mounted in the housing, the guide tube and its interface with the housing is much less affected by the vibration and thermal conditions developed during operation of the tool. In addition, the tolerances required to mount the guide tube in the housing do not have to be kept as tight as they would have to be if a conventional mounting arrangement using welds or other rigid fastening devices were used.

Title: Fabrication of lithographic plate
Inventor: INABA YOSHIMI
IPC: B41C1/10
Filed: 1988-05-16
Abstract: PURPOSE:To fabricate a lithographic plate suitable for printing many copies with low cost, by forming a photo-conductive toner layer between a pair of electrodes then applying an electric field between the electrodes and exposing an image through a transparent electrode thereby forming a photo-electrophoretic image onto a conductive base, thereafter separating the electrodes and fixing the image. CONSTITUTION:DC voltage is applied between a pair of electrodes comprising a transparent electrode 2 and a hydrophilic conductive base 3 in the dark with respect to photo-conductive toner 1, so as to bear a thin photo-conductive toner layer on the transparent electrode 2. Then image exposure such as scanning exposure through white lamp or laser beam is carried out in the dark thus producing optically excited carriers in the photo-conductive toner 1 placed at a non-image section. Toner particles on the transparent electrode 2 adhere electrophoretically onto the hydrophilic conductive base 3. Consequently, a negative image is formed on the hydrophilic conductive base 3 while a complementary positive image is formed on the transparent electrode 2. Then the transparent electrode 2 is separated from the hydrophilic conductive base 3 and the toner particles on the conductive base 3 are fixed thus fabricating a lithographic plate arranged with a negative image.

IPC: A61M25/08
Filed: 1993-04-22
Abstract: PURPOSE:To prevent the peeling of the front end of a sheath at the time of insertion of the introducer for medical purposes formed by combining a director with the sheath by specifying the structure of a part where the sheath and the director come into contact and bringing the foremost end of the sheath into elastic tight contact with the outer peripheral surface of the director. CONSTITUTION:The introducer for medical purposes which is insertable into the endotissues without damaging the tissues is constituted by fitting the director 4 into the sheath 1 consisting of an elastic high polymer having <=0.1% residual permanent set at 5% elongation for 10 minutes at room temp. The sheath 1 is so formed that its front end 3 integrally has the foremost end 2 of a sharp angled wedge-shaped section. The bore of this foremost end 2 is set at a size smaller than the outside diameter of the director 4 before the director 4 is not yet fitted. As a result, the foremost end 2 of the sheath 1 is expanded in diameter when the director 4 is fitted into the sheath 1. The foremost end 2 of the sheath is brought into tight contact with the director 4 by the recovering elasticity generated at this time at >=1mm in the state of lightly tightening the periphery of the sheath.
