Title: Method for controlling roll gap of rolling mill
Inventor: MURAKAWA TOSHIYUKI
IPC: B21B37/00
Filed: 1984-04-23
Abstract: PURPOSE:To improve the accuracy of a sheet thickness near the front end of a rolling material and to obtain a product having a high yield by setting a roll gap at a small value by a correction rate signal prior to biting to a rolling mill and returning gradually the same to a prescribed roll gap after biting. CONSTITUTION:The value to be set until the rolling material bites into the rolling mill is set at a roll gap setter 1. A subtractor 16 subtracts the correction rate alpha from an arithmetic circuit 14 for the correction rate of the roll gap to be calculated by the material, temp., sheet thickness, etc. of the rolling material from the set value RS of the roll gap from the setter 1. The subtractor applies the subtracted value RS-alpha as the corrected set value of the roll gap to an arithmetic circuit 4 via an adder 17. The roll gap of the rolling mill is thereby set smaller by the correction rate alpha than the roll gap under rolling. The correction signal of the roll gap is thereafter so generated that the prescribed roll gap is maintained since the succeeding material is bitten into the rolling mill until the material is bitten in the succeeding rolling mill.

Title: Injection molder
Inventor: TANIGUCHI TOSHIHARU
IPC: B29C45/12
Filed: 1988-03-31
Abstract: PURPOSE:To efficiently produce multikind molded items by a method wherein a movable plate, which holds the fixed molds of two sets of molds across one of molding item unloading parts and an injection part, is arranged and each fixed mold or its holder and each movable mold or its holder are held together through a detachable locking member. CONSTITUTION:The fixed molds A1 and B1 of two sets of molds A and B are held on the plate 401 of a mold carrying means 400 and respective movable molds A2 and B2 are attached to the fixed molds A1 and B1 through locking members so as to be carried to an injection part 100 and either one of molded item unloading parts 200 and 300. Since the locking member does not come off naturally due to its clamping force, no opening of molds A and B occurs during their transfer, even if the movable molds A2 and B2 are held with movable platens or cylinders. The respective molds A and B are opened by pulling the movable molds A2 and B2 and the fixed molds A1 and B1 apart with the force exceeding the clamping force of the locking member. When one set of molds is used, the transfer of the plate 401 is unnecessary, since the unloading of a molded item is done at the injection part 100.

Title: Production of powdered solder
Inventor: MITSUI TOMOKUNI
IPC: B23K35/40
Filed: 1990-03-27
Abstract: PURPOSE:To produce powdered solder for high quality cream solder by forming cooled liquid in a container by rotational centrifugal force in the form of a wall surface, injecting molten solder to the wall surface into particles and spheroidizing the broken particles. CONSTITUTION:Cooling liquid higher in vapor pressure at a normal temperature than water is put into the container 1. The container 1 is rotated by a rotation axis 2 and the liquid is formed by rotational centrifugal force in the form of a wall during rotation. The molten solder is injected from a nozzle 4 to the wall surface of cooling liquid 6. The molten solder is broken up into particles by the shearing force when it comes in contact with the surface of the liquid, a vapor layer of the liquid 6 is formed around the broken particles and the broken particles are spheroidized in a slow cooling time. The liquid is kept at a temperature of 20-60% of the melting point of solder. In this way, the powdered solder capable of preventing generation of ball solder can be produced by the rotational centrifugal force method.

Filed: 1978-06-30
Abstract: PURPOSE: To obtain good ventilation even when the wind direction is in parallel with the outside wall, by providing ventilation case of eaves type protruded out at the outside wall of a house.  
     CONSTITUTION: For taking-in air into the room, move the tip of the side baffler plates 8.8 to the center of the backside of the ventilation case. Then, the wind A blowing perpendicularly to the wall enters directly into the ventilation port 5 passing thru the front port 3 and both sides of the front baffler 6, while the wind blowing in parallel with the outside wall B.C. enters from side ports 4.4 into bentilation port 5 being guided by the plates 8.8. Thus the desired ventilation is available regardless of the direction of the wind. When ventilation is not desired, incoming air is interrupted by moving the tip of the plates 8.8 to outward, covering ports 5.5 as shown D in the figure.

Title: Electronic time-keeper
Inventor: NARITA TAKAYASU
IPC: G04G15/00
Filed: 1979-06-29
Abstract: PURPOSE: To indicate a time exceeding a set time on a single counter by actuating a down counter for up count operation when a required time is over.  
     CONSTITUTION: When a value obtained through counting a required time set by a setting means S on a down counter C turns, to zero the time will be detected by a zero detection means CS 1 , a buzzer drive controlling circuit BC drives a buzzer circuit B for a given period of time in response thereto, which comes automatically to stop after a constant period of time. Then a transfer controlling means CS 2  is actuated in response to the means CS 1  and thus causes a controlling means CC to get the counter in up count operation. On the other hand, the value and the direction at count operation are displayed on a time-keeper indicator 5 under control of a display controlling means DC. In this case, the directional display can be discriminated by reversing a simultaneous flashing of AM and PM displayes on a time indicator 5. A single counter is thus capable of indicating times passing and exceeding a set time.

When a pulse exceeding the threshold value is not present, the data are eliminated. If a pulse exceeding the threshold value is present, the data are left. The partial discharge and noise can be clearly discriminated accordingly.
