Patent JP-S632634-A (JP)
Title: Thread fastening machine
Inventor: NISHIDA YOSHIKAZU
IPC: B23P19/06
Filed: 1986-06-19
Abstract: PURPOSE:To make an engagement failure between a bit and a thread preventable from occurring, by installing a spring, energizing a thread fastening till bit to the thread fastening tool side, and a device opening the spring's pressing force temporarily. CONSTITUTION:When a plate 35 is separated from a trap lever 42, a spring bearing 34 is pushed upward by resilience of a spring, and a countershaft 27 is moved via a bearing 27 and a retaining ring 36. Since a spring 40 is stronger than a setting spring existing in the inner part of a motor-operated driver 19, an output shaft 20 is pressed to the side of this motor-operated driver 19 whereby a mechanism of a clutch or the like inside comes into a torque transmitted state. If the specified thread fastening is over, the motor-operated driver 19 is pulled up to its original position by a cylinder 25. At an up limit of the motor-operated driver 19, the plate 35 clamped to the spring bearing 34 comes into contact with a lower end of the trap lever 42, compressing the start spring 40. Therefore, resilience of the start spring 40 will no longer act on the countershaft 27 in consequence.

Title: Automatic adjusting method for control constant of pid controller
Inventor: EBISU KOJI
IPC: G05B13/00
Filed: 1986-06-19
Abstract: PURPOSE:To improve the controllability of a control system by decreasing a proportional gain when a vibration period is a constant rate smaller than the integration time of a PID controller. CONSTITUTION:A manipulated variable (u) outputted by a PID controller 1 is inputted to a controller system 2, whose output (y) is inputted to the PID controller 1 as deviation (e) which is a difference from a target value (r), thus constituting a feedback control loop. The deviation (e) is inputted to an automatic control constant adjustment part 3, which determines the proportional gain Kp to automatically adjust the control constant of the PID controller 1. At this time, when the period (p) of vibrations caused by transient deviation is smaller than the integration time Ti set in the PID controller and short, the proportional gain Kp outputted by the automatic control constant adjustment part 3 is decreased by a constant rate, and consequently an automatic adjustment is performed without causing any oscillation state and there is no deterioration in the controllability due to the adjustment.

Title: Tightening method of wheel in automobile
Inventor: MAEDA YUKIO
IPC: B23P19/06
Filed: 1985-06-28
Abstract: PURPOSE:To reduce a flutter and a shake, by bringing the peripheral surface of a disc wheel hole into contact with the peripheral surface of an axle hub on a radius, in which RFV (change of a load toward the center of a tire) of a wheel increases to a peak value, and tightening, under this condition, the tire to the hub. CONSTITUTION:In a condition that a wheel is floated from the surface 8 of land, the method, inserting a hole 2a of a disc wheel to an axle hub 4 so that a mark 3 is positioned just above the axle hub 4, tightens the disc wheel 2 to the hub by nuts 5. Here a contact point 6 of the hole 2a of the disc wheel 2 with the peripheral surface of the axle hub 4 exists on a radius R connecting the center C of the hub with the mark 3. While a hub end 7 of dimension (e) is generated between the hole 2a of the disc wheel 2 and the hub 4 by dead weight of the wheel just below the hub 4, that is, in an opposite side to the contact point 6. Accordingly, the wheel is mounted to the hub 4 eccentrically downward from the center C of the hub by a distance e/2, and the method, canceling this eccentric balance and RFV with each other, reduces a flutter and a shake.

Title: Preparation of thermoplastic polymer sheet
Inventor: HAGIWARA SATORU
IPC: B29C48/90
Filed: 1983-08-08
Abstract: PURPOSE:To prepare a polymer sheet at high speed in a stable manner, by impressing a voltage between a head and the electroconductive layer of a moving cooling body, and by lowering an electric resistance only in the part of the layer contacting with the polymer sheet by the heat of the sheet itself. CONSTITUTION:With a head 1 insulated by an insulating member a high voltage can be applied between the head 1 and a moving cooling body. Meanwhile, between the head 1 and an electroconductive film 5 a voltage is impressed from a power source unit 8. An electric resistance of a temperature-sensitive semiconductor layer 6 in the part the temperature of which turns high due to the contact with a melted polymer sheet 2 is lower than the electric resistance of the temperature-sensitive semiconductor layer 6 just before the contact with the polymer sheet 2. Consequently, a current from the high-voltage power source 8 flows into the part of the temperature-sensitive semiconductor layer 6 the temperature of which has turned high due to the contact with the melted polymer sheet 2, not flowing to the other part, between the polymer sheet 2 and the electroconductive film 5. Therefore, no minute discharge occurs between the temperature-sensitive semiconductor layer 6 and the polymer sheet 2 just before contacting with the layer 6.

Inventor: IWAMURA JIYUNICHI
IPC: A61K36/00
Filed: 1982-08-19
Abstract: PURPOSE:To separate the titled compound useful as a component of medicine, from a leguminous plant, efficiently at a low cost, by extracting a leguminous plant with an alkaline aqueous solution at room temperature, and subjecting the extract to the adsorption and elution treatments using non-polar or slightly polar adsorption resin. CONSTITUTION:At least a part of a leguminous plant is, if necessary heated in e.g. an organic solvent (e.g. n-hexane) to effect the defatting, and extracted with an alkaline aqueous solution (e.g. NaOH solution) to remove the cellulosic component. The extact liquid is optionally made acidic, and treated with non-polar or slightly polar adsorption resin. When the extract is made acidic before the treatment, the precipitate proteins are separated. The saponins and flavones adsorbed to said adsorption resin are eluted and separated by treating with a polar solvent (e.g. methanol). The eluate which is not adsorbed to the resin is if necessary subjected to the protein-removing treatment, and concentrated to obtain sugar. The treatment with the alkaline aqueous solution can be carried out at room temperature, and accordingly, the thermal energy can be saved and the product having low denaturation degree can be obtained.
