摘要:
In a method of controlling an injection molding machine M which controls specified operational processes in a molding cycle by variably controlling the rotation speed of a driving motor 3 in a hydraulic pump 2 and driving a specified hydraulic actuators 4a, 4b, . . . , in lowering the pressure Pd of the operational process to a specified pressure Pn, the pressure Pd is forcibly lowered by controlling the driving motor 3 in reverse rotation.

Gas (air) is supplied into an oil transfer line extending between a front oil chamber of an injection cylinder and an oil tank during a molding cycle, excluding an injection step, thereby preventing impact which would otherwise occur due to oil pressure generated upon start of injection in the injection step. Thus, immediately before the start of the injection step, the oil transfer line becomes empty of or almost empty of oil. Accordingly, even when high-pressure oil is supplied into the injection cylinder in an impactive manner upon start of injection, pressure oil ejected from the injection cylinder flows swiftly through the oil transfer line.

A construction machine where an operating load is transferred to a location having good rigidity, thereby ensuring the strength of a vehicle body and increasing the load-withstanding strength in relation to running loads. The frame of the lower traveling body of the construction machine comprising a hollow center frame having an upper plate with an attachment ring, a lower plate, and side plates that surrounding sides of the frame and that jut out from the attachment ring, and reinforcing ribs which connect the upper plate to the lower plate in the interior of the center frame beneath the attachment ring.

In an image forming apparatus in which a plurality of flash lamps mounted at approximately symmetrical positions are alternately lit for exposure of an original to obtain a copied image on a light sensitive film, distribution of exposures effected by the lamps disposed at the positions is made asymmetrical such that the total amount of exposure at a portion of the original undergone the most intensive exposure by the lamp lit first is minimum, while the total amount of exposure at a portion of the original undergone the least intensive exposure by the lamp lit first is maximum.

A copier for providing photographic copies of different sized originals, having an optical system variable for altering the magnification of an original, a scale member movable to locate the end of each respective size of original on the copier, and a link mechanism intercoupling the optical system and the scale to automatically vary the system magnification in accordance with the location of the scale.

A copier capable of binding copy papers at their center or their edge as desired. A bookbinding device is operatively connected to a paper outlet of the copier. To bind the papers at their center, a folding mechanism of the bookbinding device is activated first in order to form a crease along the center of each copy paper. Then, a binding mechanism of the bookbinding device is activated to sequentially stack the papers in an upwardly convex form and such that the creases face upward in alignment and, then, stitch the papers together along the aligned creases by means of a staple or the like. The bound papers are discharged to a stacking mechanism of the bookbinding device in a developed position so as to be stacked there while being folded double in the creases. When it is desired to duplicate documents on papers which are equal to or double the size of the documents and bind the copies at the center, a positional relationship between the documents and the papers is set up by a unique method.

A method for melting and treating waste to be treated such as waste water treatment sludge and incinerated ash of garbage involves mixing the waste to be treated with an auxiliary fuel in powder, granular or solid form or in the form of mixture thereof which has its own calorie value. Powder coal, coal, coke, waste plastic material, saw-dust, waste paper, carbonized material and used tires can be used as an auxiliary fuel. In addition to the auxiliary fuel, an additive is admixed for adjusting the composition of the waste to have treated so as to be a specific composition ratio.
