Title: Preparation of block copolymer from propylene
Inventor: ASANUMA TADASHI
IPC: C08F297/00
Filed: 1981-07-15
Abstract: PURPOSE:To obtain the titled copolymer having well balanced physical properties between impact resistance, rigidity, etc. by polymerizing ethylene/propylene under conditions controlled to give a specific catalytic activity. CONSTITUTION:Polymerization of ethylene/propylene is carried out continuously at a reaction ratio between ethylene and propylene <=(6/94)wt% and batchwise at a reaction ratio between ethylene and propylene of (15/85)-(95/5)wt% by the multi-stage polymerizing method in plural connected polymerizers in the presence of a stereoregular catalyst. In the process, a catalytic activity reducing agent is added to a slurry in transferring the slurry to the polymerizers for the batchwise polymerization to reduce the catalytic activity to (2/3) or less that before the addition of the catalytic activity reducing agent. The catalyst is then deactivated within the time of (1/3) or less of the polymerization time in the polymerizers simultaneously with the completion of the polymerization in the batchwise polymerizers to afford the aimed copolymer.

Title: Sample detecting device
Inventor: GOSHIYOZONO TOSHIMI
IPC: G01N15/02
Filed: 1995-05-08
Abstract: PURPOSE: To enable a sample detecting device to measure the position and particle size of a sample composed of fine particles with high accuracy without depending on an optical system by scanning the sample with a laser beam. CONSTITUTION: The laser beam A from a laser light source 1 is made incident to a galvano-mirror 2 through a lens 3. The surface 6 of a sample contained in a detection tank 7 is scanned with the laser beam A while a computer 9 controls a constant-current power source 4. A CCD line sensor 8 detects scattered light from the surface 6 of the sample and inputs detected results to the computer 9 and the computer 9 finds the intensity distribution of the scattered light from the intensity of the light at each position on the scanned surface. At the same time, the computer 9 calculates the particle size of the particles from such a relation that the scattering angle dependency of the intensity of scattered light varies depending upon the particle size.  Therefore, the position and particle size of the sample can be measured with high accuracy by not depending on the accuracy of the optical system, but only on the scanning position accuracy of the laser beam A.

Title: Control apparatus for heat-cooking appliance
Inventor: NAKAMURA MASAKI
IPC: F24C7/02
Filed: 1980-08-12
Abstract: PURPOSE: To control the cooking appliance by a method wherein a cam contact and switches for forming a main switching circuit are provided on a shaft operative through a knob and a heating power adjuster and a timer are operated through the switches.  
     CONSTITUTION: When an electric power from a commercial power source is applied across terminals (a) and (b) and the open contact 5 is closed through the operation of the knob 1, a heater 12 is energized. The heating power and the heating time of the heater 12 are determined by the angle of rotation of the knob 1, that is, the positions of switching contacts 6 and 7. When a predetermined time is reached, the timer 9 drives a motor 10 to rotate the shaft 2. The rotation of the shaft 2 opens the cam contact 5 to thereby deenergize the heater 12 and as soon as the heater is deenergized, the motor 10 ceases its rotation.

Title: Vulcanized rubber
Inventor: HIRAKAWA HIROSHI
IPC: C08L7/00
Filed: 1982-06-28
Abstract: PURPOSE:To reduce dissipation factor without lowering dynamic storage elastic modulus, by swelling a vulcanized rubber contg. reinforcing carbon black and exhibiting high dynamic hysteresis loss with an extender oil mainly composed of low-molecular hydrocarbon. CONSTITUTION:30-70pts.wt. reinforcing carbon black is blended with 100pts.wt. raw rubber such as natural rubber or polyisoprene rubber. Then the rubber is vulcanized and impregnated with an extender oil mainly composed of low- molecular hydrocarbon to swell the rubber at a degree of swelling of 2-10wt%, thus obtaining the desired vulcanized rubber. By swelling the vulcanized rubber with the extender oil, neighboring carbon aggregates in the rubber are slightly separated from one another, whereby dynamic hysteresis loss is reduced. Hence, when used for tire tread rubber part, the rolling resistance of tire can be lowered.

Title: Speed controlling method for hydraulic elevator using inverter power supply
Inventor: HASEGAWA FUMINORI
IPC: F15B21/14
Filed: 1990-04-25
Abstract: PURPOSE:To enable smooth operation when downward motion is started and enhance the comfort in riding in the cage by operating an oil pressure pump in the direction of returning the working oil for a certain period to an oil tank in order to lessen the starting resistance of the oil pressure pump and a motor when the elevator is started for lowering. CONSTITUTION:Before going into inverter control and prior to opening of a control valve 6, a power supply for a motor is turned on, and an oil pressure pump 2 is rotated in the direction of returning the working oil in a passage 15 back to an oil tank 3 so as to nullify the starting resistance, and after a short time the power supply to motor is shut off. Because this operation puts internal pressure of the passage 15 negative, the working oil in the oil tank 3 passes through a check valve 16 to be supplied to the passage 15, passes through the pump 2, and returns to the oil tank 3 to close a circulation. Then the working oil in the cylinder 4 is allowed to flow into the passage 15 by opening the control valve 6 so as to pressurize. At the same time, the oil is returned to the oil tank 3 via the pump 2 to start lowering of the elevator 7. After the pump 2 is rotated forcedly, control of an inverter control power supply 11 is carried out.

Title: Control method for pump turbine
Inventor: HAYAKAWA KEIZOU
IPC: F03B11/04
Filed: 1980-08-11
Abstract: PURPOSE: To prevent the generation of a secondary flow during the high head operation of a pump turbine by detecting a differential water level between an upper water reservoir and a lower water reservoir and by controlling the opening of a guide vane in response to a variation of the water level of the lower water reservoir according to a preset opening curve.  
     CONSTITUTION: As for a differential water level H 0  between an upper water reservoir and a lower water reservoir where a secondary flow is generated, the noise and vibration are small when the water level of the lower reservoir is higher. When the water level of the lower reservoir drops, a secondary flow accompanied by cavitation is easily generated. In this case, vibration is prevented when the opening of a guide is throttled in response to a water level drop in the lower water reservoir. As for curve Z which controls the opening of the guide vane for a pump turbine, the water level of the lower reservoir and the opening of less noise and vibration are obtained by making a test with differential water levels H 0  to H max  where a secondary flow may occur, thereby establishing a group of opening curves such as curves B 1 , B 2  and B 3 .

Abstract: PURPOSE:To supply a constant flow rate of fluid by disposing a secondary pressure control valve which controls the effective valve seat area according to the pressure change in a pilot outflow passage, opening the secondary pres sure control valve by a constant amount at the time of opening a solenoid valve in the outflow passage, and controlling the opening of a main valve. CONSTITUTION:When a solenoid valve S is closed under the condition of an inflow passage 3 supplied with water, a pilot outflow passage 11 is closed, water in the inflow passage 3 raises the pressure from a pilot inflow passage 10 to a pressure control chamber 8, and together with a spring 9 closes a main valve 5. When the solenoid valve S is opened, water in the control chamber 8 is drained to an outflow passage 4, the pressure in the control chamber 8 is lowered, the main valve 5 is raised, and water is sprayed out for example from five sprinklers. When ten sprinklers are opened, the water pressure in the outflow passage 4 decreases, the control valve 16 increases its opening area with the pressure decrease at a downstream position G of the control valve 16, the pressure in the control chamber 8 further decrease, and the opening area of the main valve 5 increases. As a result, the water flow rate is prevented form decreasing.
