Inventor: KOBAYASHI YOSHITAKA
IPC: B29C43/34
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To produce a multilayered molded product good in appearance at a low cost without damaging the feel of a skin material and generating the damage of cushioning properties caused by the collapse of a foam layer, even if the skin material having the foam layer is used, while putting the merit of an injection or compression molding method capable of laminating the skin material to a base material simultaneously with the formation of the base material to practical use.

Title: Controller for melt amount of high frequency induction heating type evaporating source
Inventor: NAKAYAMA IZUMI
IPC: C23C14/24
Filed: 1981-08-19
Abstract: PURPOSE:To provide a titled device which measures the melt amt. of the material to be evaporated in a crucible relatively accurately and supplies the material so as to keep said amt. constant by providing a voltage detector which detects the voltage from a high frequency power  source to a coil for heating and melting the evaporating material in the crucible and supplying  the evaporating material and stopping th supply thereof in accordance with the detected value thereof. CONSTITUTION:When the evaporation of a material 5 to be evaporated such as Al in a crucible  2 advances and the amt. thereof decreases, the voltage detected in the chopper output part 6  of a coil 3 increases. When the voltage attains the set value in the high voltage detecting part  8 of a voltage detector 7, a relay 10 operates and instructs the supply of the material 5 such as  wire-like Al to the crucible 2. when the voltage detected with the detector 7 decreases gradually on account of the supply of the evaporating material and drops down to the voltage value  set in the low voltage detector part 9 of said detector, a relay 11 operates, thus stopping the  operation of the above-described supplying device. The amt. of the evaporating material in the  crucible 2 is maintained roughtly constant by repetition of plural times of the supplying and  stopping, and the accurate supplying of the material 5 and the large change in the load impedance of the coil 3 are prevented.

Abstract: PURPOSE: To provide low purity Al foil with formation property and chemical conversion film characteristics of the same degree as of high purity Al foil, by forming hydrolysis product layer such as alkoxide on the surface of Al foil, and processing by anodic oxidation after heat treatment.  
     CONSTITUTION: Al foil of a relatively low purity is dipped in a solution comprising dissolving aluminum alkoxide or othere such as aluminum propoxide, aluminum isopropoxide into organic slovent such as ethyl alcohol and toluen, by 1W10%. This foil is dried naturally in the air, and is then put into boiling water, allowing to boil for about 3 minutes to form a hydrolysis product layer of alkoxide on the surface of Al foil. Then, the foil is baked at 400°C for 3 minutes, and is treated by anodied film forming. As the electrolyte for anodic oxidation, an aqueous solution of one or more kinds of acid or salt of boric acid, phthalic acid or citric acid is used. The chemical conversion film of the same degree as of high purity Al may be formed, so that this foil may be effectively used as Al foil for electrolytic capacitor.

Title: Method and device for continuous tapping from blast furnace
Inventor: NIKO KIYOSUKE
IPC: C21B7/14
Filed: 1981-08-20
Abstract: PURPOSE:To make the continuous tapping for a long time possible by tapping molten  steel through the tap hole of a blast furnace while forcing plastic granular refractories  through the holes penetrated through the hearth wall around the tap hole higher than  the tap hole level of the blast furnace. CONSTITUTION:For example, two relining holes 4 are provided around a tap hole 2 in  the position higher than the level of the hole 2 in such a way that the inside ends  thereof arrive at the parts near the inside end of the hole 2. When plastic granular  refractories are forced through the holes 4 into the parts around the inside edge of the  hole 2 where the side wall in the hearth is worn most intensively by molten iron and  molten slag, the refractories 5 are calcined and solidified as shown in the figure, and  the worn parts are relined. The molten iron and molten slag tapped through the hole 2  from the inside of the hearth 1 flow into the tapping spout 3 below the outer side of  the hole 2 and are charged into a ladle, etc. The above-described refractories may be  forced into the holes either intermittently or continuously. The restrictions of the continuous tapping time per time by the abrasion of the side wall parts of the hearth are  eliminated, the durability of the hole 2 per se is improved on account of a uniform and gentle tapping speed and the purpose is achieved.

Title: Dish-washing machine
Inventor: OYA HIROSHI
IPC: A47L15/23
Filed: 1990-05-18
Abstract: PURPOSE:To prevent shifted wear of a nozzle shaft, and to make smooth rotation thereon, by a method wherein a rotary seal surface on which washing water is axially sealed between a washing nozzle and the nozzle shaft, is provided and a lint-made seal is provided on the rotary seal surface and on the lateral sliding surface. CONSTITUTION:When washing water is fed into a nozzle shaft 25 through a flow way 32, the washing water is jetted from a jet hole 30, and thus a washing nozzle 26 rotates. At this time, by a static pressure of the washing water, the washing nozzle 26 is brought into close contact with the nozzle shaft 25 through a flange part 27b on a lint-made seal 27, and is slidably rotated while the washing water is being prevented from leaking. During the rotation of the washing nozzle 26, a lateral load caused by the dead weight of the washing nozzle 26 is supported by the nozzle shaft 25 through a sleeve part 27a of the seal 27, and thus the wear on the nozzle shaft 25 is decreased. Since the seal 27 rotates centering around the nozzle shaft 25, the seal 27 itself does not cause unsymmetrical wear.

Abstract: PURPOSE:To prevent that an impact becomes large when a writing utensil lands with out being sufficiently decelerated by stepwise reducing the deceleration force to the writing utensil at each time when the writing utensil approaches a drawing surface and applying writing pressure to the writing utensil in a drawing surface direction when a deceleration period is completed. CONSTITUTION:In an automatic drawing apparatus equipped with a sensor detecting the vertical position of a pen 2, initial acceleration force Fsd is applied to the pen 2 by a controller. It is judged whether or not the pen is lowered from the previous position by a preset distance 1 and acceleration force of the value calculated by subtracting (x) from Fsd is applied to the pen 2. When the position of the pen 2 reaches an acceleration/deceleration change-over position, initial deceleration force Fsu is applied to the pen 2. Subsequently, it is judged whether or not the pen 2 is lowered by a distance 1 from the previous position thereof and deceleration force of the value obtained by subtracting Fsu by the reduction value (y) of preset force is applied to the pen 2. Further, it is judged whether or not the position of the pen 2 reaches a DOWN position to apply writing pressure Fhi and it is judged whether or not pen jumping is generated and, when no pen jumping is generated, falling operation is completed and, when pen jumping is generated, jumping force is further applied.

On the other hand, a stress is concentrated at the damage layer 11, the concentration of the stress at an edge part of the silicon island region is relaxed and accordingly, a dislocation region is not formed. By this setup, a semiconductor device, electrically more efficient is obtained.
