Filed: 1985-10-14
Abstract: PURPOSE:To perform crystal growth by forming a layer of a composition which is hardly thermally deformed and melt-back at epitaxially growing time at the end of a projection of irregular portion formed on a main surface to allow the irregular portion to faithfully remain. CONSTITUTION:After an N-type InGaAsP layer 2, a P-type InGaAsP layer 101, and a P-type InP layer 102 are formed on an N-type InP substrate 1, diffraction gratings 103 are formed on the layers 101, 102. Then, when a P-type InP layer 104 is formed by a liquid-phase epitaxially growing method on the gratings 103, since the layers 102 remaining on the ends of the projections are hardly thermally deformed or melt-back, the shape of the layer 101 does not alter. Then, the shape of the diffraction grating 103' after crystal growing can faithfully remain in the irregular shape of the layer 101. A semiconductor laser having preferable characteristics can be manufactured by this method.

The current value of the sheet ion beam is measured by an ammeter 46, and the value is compared with a set value by a drive controller 47, and the moving speed of the holder 43 in the direction of Z-axis is regulated by the signal of the controller 47 according to the comparing result. That is, when the radiating. amount is larger than a specific value, the speed of the holder is increased, and when it is smaller, the speed is reduced. Consequently, the radiating amount of the sheet ion beam radiating on the sample 44 is regulated so as to improve its evenness.

Title: Image forming device
Inventor: TAMAOKI JUNICHI
IPC: G03G15/20
Filed: 1988-09-13
Abstract: PURPOSE:To prevent a blocking phenomenon of a sheet by switching an image forming cycle to a low cycle when a detected temperature is equal to or exceeding a specified value. CONSTITUTION:The temperature of the sheet to which thermal fixation processing is performed is detected by a thermistor 61 being a detection means. When the detected temperature is equal to or exceeding the specified value, the image forming cycle is switched to the low cycle with the aid of the action of a control means 65. Then, each sheet is supplied at intervals longer than usual so that an image is formed on the sheet in the case of continuous copying. Therefore, a standing time which is from ejecting a previous sheet till ejecting the next sheet becomes longer even if the temperature of the sheet to which thermal fixation is performed rises to such an extent that the blocking phenomenon occurs in a usual case. Thus, the blocking phenomenon can be prevented.
