Filed: 1979-03-02
Abstract: PURPOSE: To obtain a methyl ether derivative, by reacting an alcohol with diazomethane in neutral conditions, using a solid catalyst comprising silicon oxide or aluminum oxide.  
     CONSTITUTION: In the preparation of a methyl ether deriuative by reacting an alcohol with diazomethane, a solid catalyst comprising silicon oxide or aluminum oxide is used as a catalyst. A catalyst having silica, alumina or alumino-silicate, e.g., a neutral silica gel, silicic acid, is preferably used. OH of β-hydroxy-ketone, e.g., prostaglandins E 1 , E 2 , etc., which undergoes direct methylation of alcoholic hydroxyl group with difficulty, can be methylated with ease by the use of the catalyst. Various stable alcohols can be methylated with ease.

Title: Semiconductor light emitting device
Inventor: FUKUDA MITSUO
IPC: H01S5/00
Filed: 1989-01-31
Abstract: PURPOSE:To prevent the deterioration of oscillation spectrum and improve characteristics by arranging a plurality of electrode isolation trenches, making the bottom parts thereof reach current blocking layers, and electrically isolating electrodes. CONSTITUTION:Electrode isolation trenches 10 are dug up to current blocking layers 6, 7, in the manner in which the distance between the rough of the trench and an active layer 1 becomes (d). Hence, the isolation resistance between electrodes becomes nearly equal to material resistance of a clad layer 3 of the following dimension; the depth is (d), the width is nearly equal to the width of a light emitting region, and the length is equal to the width of the trench 10. As a result, high resistance is easily realized. When the trench width is small, the length of a region in which the current of an active layer 1 is not injected can be neglected, and current-optical output characteristics of the device do not change. Thereby, P-side electrodes 9 can be isolated by the trench 10 without deteriorating distributed feedback type semiconductor laser, and oscillation wavelength is changed by making nonuniform current flow in the active layer 1. Further, a modulation signal can be applied to one of the P-side electrodes 9, and stable modulation characteristics are obtained, so that characteristics of the device are improved.

Abstract: PURPOSE:To make accumulation possible without a collision of carried goods by providing a carrier detector to individual carrier pitches of a roller conveyer divided by carrier pitches, and making the action of the adjoining detector to be transferred to carrier pitches in the reverse carrier direction successively and to be stopped. CONSTITUTION:When a detecting roller 11' is depressed by carried goods, a locker arm 10' is depressed to an interferable position with a locking part 9' of a wheel 8' by a detecting arm 13'. However, when no carried goods exist on a detecting roller 11 adjoining the downstream side, carried goods are carried with interference eliminated as a detecting arm 13 is abutted to a stopper 15 and the locker arm 10' is pulled. But when the detecting roller 11 is depressed by an operator etc., a locker arm 10 is pushed in the reverse carrier direction by a rod 17'', interferes with a lock part 9 of a wheel 8, and carrying is stopped. And the action is transferred to succeeding carrier pitches similarly and successively and accumulation is made. Thus collision is prevented.
