Title: Ridge type semiconductor optical amplifier
Inventor: IMOTO KATSUYUKI
IPC: H01S3/10
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a ridge type semiconductor optical amplifier which enables a switching operation with high speed and is low in cost. SOLUTION: After a lower clad layer 21, an active layer 22, an upper clad layer 23 and a contact layer 24 are successively formed on a semiconductor substrate 20, the contact layer 24 and the upper clad layer 23 are processed so as to form approximately a rectangular shape. By doing this, since crystal growth is necessitated just once, the production cost can be reduced when forming an SiO2 layer 26 and a polymer layer 27. The forming process of the SiO2 layer 26 and the polymer layer 27 are inexpensive processes compared with the process of crystal growth. And, by using the SiO2 film 26 having a low dielectric constant and a polymer layer 27, a parasitic capacitance can be reduced. As a result, a high-speed optical switching operation can be performed.  Moreover, an etching is carried out so that the widths of the upper clad layer 23 and the contact layer 24 become narrower as tapered at the incident and exit side of the signal light. Consequently, the device can be highly efficiently connected with the optical fibers at both sides faces.

Title: Control device for vending machine
Inventor: TAKAMATSU EIJI
IPC: G07F13/00
Filed: 1990-10-24
Abstract: PURPOSE:To make the switching operation for setting preferential operation unnecessary by setting automatically which is to be operated preferentially a heating device or a cooling device and an ice making device from the sales number of cold drinks during prescribed time in the past. CONSTITUTION:The sales number of the cold drinks during every prescribed time is calculated cumulatively by a counter C, and it is decided whether the result exceeds the prescribed number to be a standard or not by a deciding means D. When the deciding means D decides that the value obtained by the counter C is over the prescribed value, it is decided that there was a larger demand for the cold drink than a hot drink, and the cooling device B1 and the ice making device B2 are operated more preferentially than the heating device A by a control means E. On the other hand, when the value obtained by the counter C is below the prescribed value, it is decided that there is a larger demand for the hot drink than the cold drink, and the heating device A is operated more preferentially than the cooling device B1 and the ice making device B2. Besides, in the case of the hot drink, the above-mentioned operation is reversed. Thus, the preferential switching of the hot drink and the cold drink can be executed as making the decision of an operator unnecessary.
