Abstract: PURPOSE:To contrive shortening of detaching working hours of a heating cylinder head, by a method wherein the heating cylinder head clamped mutually detachably to the tip part of a heating cylinder of a molding machine body under a state of screwing-on is turned by converting forward movement force of an injection device to a stationary platen into turning force and clamping or slackening of the heating cylinder head is performed. CONSTITUTION:Two pairs of the first and second wedgy guide slopes 21, 22, whose tilting directions are different from one another alternately in a circumferential direc tion are formed in a projected state on the surface 20a of a stationary platen 20 of a mold clamping device. At the time of clamping or slackening of a heating cylinder head 7 to a heating cylinder 4 of a molding machine body 1, an injection device 2 is moved forward and a guide protrusion 14 of a handle member 10 connected with the heating cylinder head 7 abuts selectively against either of the first and second wedgy guide slopes 21, 22 for sliding. With this construction, its forward movement force F is divided into a component force F1 or F2 of a vertical direction, converted into a turning force, the heating cylinder head 7 is turned in the direction X or Y and clamping or slackening is performed.

Abstract: PURPOSE:To reduce the loss of a laser by forming continuously connected electrodes in the direction of a cavity length on the surface of a water, by forming a long cavity element by cleaving the wafer to the integer times of a basic cavity length and by making a chip of the basic cavity length or the integer times of the basic cavity length after evaluating the light emitting property of the long cavity element. CONSTITUTION:A semiconductor layer structure of the integer times of a basic cavity length L, in this example, two times, is formed on a wafer 1. Continuously connected electrodes 8A are formed in each basic cavity on the surface of the water 1. In this case, the width of the electrode 8A is made narrower in order to make a cleavage easy for each basic cavity length. If an LD of twice the cavity length is formed, a current flows in the middle point and the loss is reduced since the electrode has such a shape. Each LD in an array is inspected a light output, a wavelength and the width of a spectrum by a probing equipment. If the width of the spectrum satisfies the standard for inspection, a chip is made as a long cavity element. In the case of defective one, cleaved to the basic cavity length and the property of the LD is evaluated.
