Title: Dwelling control method and apparatus in injection molding
Inventor: YAKIMOTO KAZUTOSHI
IPC: B29C45/77
Filed: 1993-05-17
Abstract: PURPOSE:To control the quality of a molded product with high accuracy by calculating the pressure of the resin in a mold at a specific time and calculating a dwelling set value necessary for achieving the pressure of the resin and controlling dwell pressure on the basis of the calculated value. CONSTITUTION:At the point of time immediately before a screw advances at the beginning of the filling stage of a molten resin to a cavity, the temp. of the tip part of a nozzle, the temp. of a sprue part, the temp. of the wall surface of the cavity and the temp. of cooling water are measured and, on the basis of the measured values, the temp. of the resin in a mold at the time when the wt. of a molded product at a dwelling stage is decided is estimated. Subsequently, the pressure of the resin in the mold at this time is calculated from the estimation value and a dwelling set value is further calculated. At a dwelling stage, dwell pressure is controlled on the basis of this dwelling set value. By this constitution, the fluctuations of the quality of a molded product caused by a temp. change are eliminated by simple constitution without providing a resin pressure sensor and a resin temp. sensor in the mold and the molded product having high dimensional accuracy can be stably produced.

Title: Three way fluid control valve
Inventor: HAMAMOTO SATOSHI
IPC: F16K29/00
Filed: 1985-06-27
Abstract: PURPOSE:To prevent misoperation of an actuator by operating a second spherical valve member which is conjoined with a first spherical valve member for controlling ports, when the supply pressure exceeds a set pressure. CONSTITUTION:When an actuating member 18 is in its operative condition, it moves a first spherical valve member to a first position, permitting communication between a load part (b) and a pressure supply port (a) and interrupting communication between the load port (b) and a return port (c). At this time, the first spherical valve member 11 is in abutment against the second spherical valve member 10 and permits flow of pressure oil from the pressure supply port (a) to the load port (b), when the pressure of the pressure supply port (a) is lower than a set pressure. When such an abnormal pressure as to exceed the set pressure is generated in the pressure supply port (a), the load port (b) is closed with respect to the pressure supply port (a) to prevent misoperation.

Title: Ice crusher
Inventor: HOSHINO SHOJI
IPC: B02C18/12
Filed: 1990-05-29
Abstract: PURPOSE:To make shaved ice or coarse ice-flakes by a simple selecting-operation, by a method wherein when an operating lever is operated, a cylindrical body is vertically moved by a vertical movement mechanism, and when the cylindrical body is moved downward, the position of the lower end of the cylindrical body is made lower than that of the lower end of a throwing case. CONSTITUTION:By rotation of a rotary disk 25, a crushing edge 28 collides with ice-lumps in a cylindrical part 31a, and the ice-lumps are crushed one after the other and turned into small ice-flakes crushed. By centrifugal force caused by rotation of the rotary disk 25, the crushed ice-flakes are discharged outward through a gap L1 formed between the lower end of the cylindrical part 31a and the end part of upper surface 26a of a cylindrical part 26, and enter a chamber 45 formed of a cylindrical body 32 and the cylindrical part 26. Since the gap L1 is relatively large, the ice-flakes entering the chamber 45 are coarse. The crushed ice-flakes in the chamber 45 are shaved by a slicing edge 29 and are turned into fine ice-flakes. Since a gap L2 formed between the lower end of a cylindrical part 32a and the rotary disk 25 is small, only the fine ice-flakes are discharged from the gap L2 by the centrifugal force of the rotary disk 25, and fall on a bottom part 30c of a vessel 30. By a blade H formed on the undersurface of a flange part 27 of the rotary disk 25, the fine ice-flakes are scraped up with rotation of the rotary disk 25, and are discharged to a discharge opening 30b through a branch way 30a.

Abstract: PURPOSE:To provide a hair-raising agent and a shampoo each containing as an active ingredient a mulberry white bark extract obtained by extracting mulberry barks with a hydrophilic organic solvent or its aqueous solution add subsequently with an oleophilic organic solvent. CONSTITUTION:Mulberry white barks, the root barks of Morus alba Linne or other plants which belong to the same kind are extracted with a hydrophilic organic solvent (especially preferably methanol, ethanol or acetone) or its aqueous solution. The extraction solution is concentrated to evaporate off the solvent, and the organic solvent layer is separated and subsequently subjected to the distillation of the solvent to obtain a dried ingredient having a hair- raising action (the two stage extraction method may be reverse). The hair- raising agent contains the mulberry white bark extract as an active ingredient. The shampoo also contains the extract as an active ingredient. The hair-raising agent is especially applied to scalp for the therapy and prevention of alopecias such as masculine alopecia and diffused alopecia. The above-mentioned active ingredient has a high hair growth period-changing ability, exhibiting a remarkable hair-raising effect, and is safe.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of smoke, NOx and HC by performing lean uniform premixed combustion. SOLUTION: This engine is constituted to ignite fuel and intake air injected into a cylinder 2 for a fuel injection nozzle 3 by compressing them by a piston 6. In this case, it has a fuel injection nozzle 3 having a plural number of small nozzle holes of less than 0.1 mm in diameter and a control means to make injection timing of these small nozzle holes during an air intake stroke or a compression stroke of the engine. Fuel injected from the small nozzle holes is roughly vaporized immediately after injection, and a lean and uniform mixture is formed in the cylinder 2 while the piston 6 reaches a top dead center.  Thereafter, when the piston 6 reaches the neighborhood of the top dead center, the inside of the cylinder 2 becomes high temperature and high pressure, and accordingly, the overall mixture is roughly simultaneously ignited and burns in a roughly overall region of a space inside the cylinder 2, and lean and uniform premixed combustion is attained.
