Conical plates 4, 6 approach one another due to the movement of the conical plate 6 by an adjusting nut 9, and an effective diameter of an abutting part (s) becomes larger thereby, while the conical plates 4, 6 are separated with one another, and the effective diameter of the abutting part (s) becomes smaller thereby. When an outer diameter of the abutting part (s) is larger, the interval between the pressing member and the circumferential surface of the work W through the copy ring 13 becomes larger, whereby the size of the notch made by a cutter 2 is reduced. When the outer diameter is smaller, the size of the notch can be made larger.

Abstract: PURPOSE:To improve durability of a rotary driving device by installing a clutch mechanism for absorbing the impact load which is generated on the restraint for a load shaft between the load shaft and an output shaft and preventing an impact load over a certain value from being applied onto a motor and a reduction gear device. CONSTITUTION:When a load shaft 9 is revolved by the revolution angle of a rotary body, the revolution of the load shaft 9 is restrained by a stopper 95, etc. Even if an electric power is cut off simultaneously with the restraint for this revolution, a geared motor consisting of a motor 10 and a reduction gear device 13 is revolved a little by the inertia power,and an impact force is generated between the restrained load shaft 9 and an output shaft 2 which is revolved a little. A movable clutch 4 formed integrally with the load shaft 9 in a clutch means is separated from a fixed clutch 3 on the output shaft 2 side by this impact force against a spring 43 force. The impact force is lightened by revolving and turning the output shaft 2 side only through this separation. Therefore, the transmission of the impact force over a certain value to a motor 10, etc., can be avoided.

Title: Method of measuring quantity of chemical injected into ground
Inventor: MIYAMOTO TAKESHI
IPC: E02D3/12
Filed: 1992-07-01
Abstract: PURPOSE:To simplify treating and to improve reliability by applying negative pressure to consolidated soil taken from the ground where chemical feeding treatment is provided and by finding out the relationship between the negative pressure applied and the water content of the consolidated soil. CONSTITUTION:Negative pressure is applied to the soil taken from the ground in an undisturbed condition where chemical feeding has been provided, and water in the soil is extracted; and the quantity of chemical which has been fed is estimated from the changes in relation of the negative pressure applied and the volume of water removed. In other word, the changes in relation of the water quantity removed and the negative pressure applied indicate the volume of the gel and the consolidated soil formed by chemical feeding because the quantity of water removed from the soil is reduced in proportion to the increase of gel formed in the ground and the formation of the consolidated soil by chemical feeding. Therefore, by calculating the reduced quantity of water extracted from the soil in proportion to the negative pressure applied, the quantity of chemical fed into the ground is calculated. The above method simplifies the treatment operation.

Filed: 1982-10-04
Abstract: PURPOSE:To prevent scattering of a toner for toner supply by providing a flexible cover which consists of a flexible film and is provided with a junction part which can form a space for toner supply, on a vessel of the toner for copy. CONSTITUTION:Two flexible films 3 are shaped like a fan-shaped section, that is, a downward spike state and are brought into contact with each other near the center to form a flexible cover 4.

IPC: G06Q10/10
Filed: 1988-07-15
Abstract: PURPOSE:To minimize the input mistakes due to the improvement of the input speed by informing a fact that an input skip unable word is included in each word. CONSTITUTION:For instance, a declaration means (c) like a line feed key declares totally that the input actions of words are skipped (no input carried out) in a cluding the word which is presently guided for input through a prescribed word in the subsequent input order. Then a detection means (d) checks via a memory means (a) whether or not an input skip unable word which should be inputted is included in a word group where no input is decleared. An information means (e) informs a fact that an input skip unable word is detected by the means (d) and urges the input of the relevant word. Thus it is possible to minimize the input mistakes due to the improvement of the input speed.

Abstract: PURPOSE:To enhance the power factor with a simple and small additional circuitry by inserting a capacitor in parallel with or series to the primary or secondary winding of a booster transformer, which boosts the pressure of high frequency electric power and supplies it to a discharge lamp. CONSTITUTION:Commercial AC power is fed from a terminal 10 to generate a high frequency voltage by a self-exciting oscillator circuit of lower type, and it is reduced to approx. 8V in the same phase and emitted from secondary windings 34, 39, 40 of a reduction transformer 17. This is sent to booster transformers 42-45 via transmission lines 41, 42, and upon boosting to a specified voltage, is fed to discharge lamps 70-72. In this constitution drop of the power factor due to influence of the inductance of the reduction transformer and booster transformer is compensated by inserting capacitors 58-61 in parallel with or series to primary windings 46-49 or secondary windings 50-53, 54-57 of the transformers 42-45. Thus the power factor can be enhanced with a simple and small additional circuitry.
