Title: Production of slurry of elastic ethylene copolymer
Inventor: MAURIZIO GALIMBERTI
IPC: C08F232/08
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To obtain the subject copolymer through the slurry process which causes no contamination of the reactor and readily recover the polymer by adding a low-boiling saturated hydrocarbon solvent to the reaction medium comprising a mixture of liquid propylene, ethylene and the like. SOLUTION: A mixture containing ethylene, propylene and optionally polyenes is subjected to slurry polymerization in the presence of a catalyst system containing a compound of a transition metal M selected from Ti, V, Zr, and Hf bearing at least one of M-π bond in a reaction medium containing 5-60wt.%, based on the whole liquid phase, of a 5-9C saturated hydrocarbon solvent lower boiling than cyclohexane thereby giving a copolymer containing 45-80% of ethylene-derivative units, 20-55% of propylene-derivative units, and 0-15% of polyene derivative units. Whereby the slurry is stabilized, an elastic ethylene copolymer can be produced with no occurrence of contamination of the reactor due to adhesion of rubber-like substance and the final product can be readily recovered.

IPC: H01L21/50
Filed: 1986-07-26
Abstract: PURPOSE:To simplify the attachment and the detachment of a magazine by providing a longitudinal relief at the position of a lead frame conveying passage where a rotor exists in the magazine. CONSTITUTION:A lead frame 3 flows on a small route of a rotor 4 with the step of the rotor 4 as a guide, and temporarily stops in a magazine 1. When next machine is operated, an elevator 6 does not move, but it is conveyed by the rotor 4 to a lead frame machine. When the machine is stopped, the elevator 6 rises at one pitch of a pawl 2, the frame 3 is engaged by the pawl 2 and stored in the magazine 1, a pawl 2 next to the pawl 2 becomes waiting for the frame 3 to sequentially store the frames. When the next machine starts operating, the frame 3 stored due to the drop of one pitch by the elevator 6 when the flow of the frame 3 is stopped is returned onto the rotor 4, and the frames 3 in the magazine 1 are sequentially discharged. Thus, since a relief of the rotor is formed at the magazine, the magazine can be simply attached to or detached from the midway of the frame conveying passage.

Abstract: PURPOSE:To prevent rotation unevenness, noise generation by a brush, or residual dust while a cleaner stops by rotating a rotary brush by using an idler for rotating force of a record to remove dust on the record. CONSTITUTION:When a cleaner case is turned toward the direction of a turntable shaft 14 and a guide part 13 is inserted into the turntable shaft 14, an idler 6 makes contact with a level part 19 of a record 17 by a sheet spring 18 to be rotated, and the rotary brush 2 is rotated by gears 5 and 1 in the direction of A.

Title: Automatic shut-off device for cooking utensil
Inventor: ITO KATSUMI
IPC: F24C3/12
Filed: 1991-06-20
Abstract: PURPOSE:To improve a scorching prevention capacity of an automatic shut-off device for a cooking utensil based on a detected value of a pan bottom temperature by temperature sensor. CONSTITUTION:When the rate of change (gradient) of a sensor temperature ranges from 10 to 4 deg.C/minute and continues for 60 seconds, food under cooking is decided to be boiling. When food is boiled down and the gradient of the temperature continues to exceeds a specified rise gradient (4 deg.C/minute) for 10 seconds, the heating power is throttled to (the point A). The cooker is shut off when the temperature rises by 10 deg.C from the temperature at which the specified rise gradient is exceeded. In this case, the difference between the temperature of the central part of the pan bottom (sensor) and the temperature of the pan bottom outer peripheral part is minimized, thereby preventing the outer peripheral part from being scorched.
