Filed: 1987-08-04
Abstract: PURPOSE:To enable matching of frequency of generated power with a reference frequency even for independent operation, by providing a means for setting an independent reference frequency during independent operation of an induction generator. CONSTITUTION:An excitation controller 7 controls a cycloconverter 3 according to a deviation  f between rotary speed N of an induction generator 1 and the frequency (f) of a power system 4 and produces secondary exciting current having slip frequency corresponding to the deviation  f. Consequently, output frequency of the induction generator 1 is matched with the frequency of the power system 4. A governor 5 controls the opening beta of a guide vane 9 corresponding to a deviation  P between a command value PC of generated power and an output P from the induction generator 1. When the induction generator 1 is connected to an independent load, reference frequency set in a reference frequency setting circuit 21 is provided to a switching circuit 22.

Abstract: PROBLEM TO BE SOLVED: To generate fixed or semi-fixed formant tones by setting the delay time of a delay means according to the pitch of the generated musical tones and making the period of an initial waveform signal not proportional to the pitch. SOLUTION: A control circuit 5 delivers a reset signal RS in correspondence to the key-on timing of the musical tone to a counter 3 and inputs the F number (delay time information value) ΔF corresponding to the pitch of the musical tone to a phase accumulator 1.

The sample point date is read according to the address signal out of the waveform memory 4 and is inputted to a delay feedback type musical tone synthesizing algorithm 2. At this time, the delay time of the delay means in the delay feedback type musical tone synthesizing algorithm is set according to the pitch of the generated musical tone and the period of the initial waveform type signal is so controlled as not to make the change proportional to the pitch.

Title: Semiconductor vertical-lateral direction array laser device
Inventor: TAKAMI AKIHIRO
IPC: H01S5/00
Filed: 1990-07-23
Abstract: PURPOSE:To realize a simple wafer process in which a crystal growth process is carried out only once and the diffusion of impurities and the formation of an insulating film are not executed by a method wherein many oblique grooves are previously provided to a substrate possessed of a plane (100) as a primary face so as to make a plane (-1-1-1) and a (-l-1-1) plane exposed. CONSTITUTION:Oblique grooves are previously provided to a P-type GaAs substrate 2a possessed of a plane (100) as a primary face so as to make a plane (100) and a plane (-1-1-1) exposed. A boundary line 12 of a PN junction is a natural diffusion line of Zinc. Provided that a P-type AlxGa1-xAs clad layer 3 is doped with zinc twice as high in concentration as an N-type AlxGa1-xAs clad layer 5, a doping boundary is made to move as Zinc is diffused by heat during the growth of crystal. At this point, Zinc is diffused faster in a direction (1111) than in a direction (100), so that a PN junction is located inside an active layer 4 on a plane (100) but the diffusion of zinc is made to proceed on a plane (111) until it reaches to the N-type AlxGa1-xAs clad layer 5, and a PN junction is located inside the N-type AlxGa1-xAs clad layer 5. In this case, As the PN junction located inside the active layer 4 is lower than that located inside the clad layer 5 in potential, a laser oscillation takes place in this part but not in the other part. As the active layer 4 is located close to the P-type GaAs substrate 2a in a groove, laser oscillation is prevented from occurring there due to a large loss induced by absorption.

Abstract: PURPOSE:To use a narrow space effectively by providing hanging rods for sequentially spacing each pair of steps of paired storing rails each other from the above, the space between paired storing rails positioned below a storing conbeyer mount portion being reduced. CONSTITUTION:The uppermost paired storing rails 5 are elevated by an elevating chain 9, and the lower rails 5a-5d are hung by hanging rods 12, and at the time of being hung down, the rails are kept at fixed intervals. At the time of being lowered, the lowermost paired rails 5d are brought into contact with a support table 11 of a cheese stocker, so that the supporting point of the hanging rod 12 is moved to reduce the space between the storing rails sequentially. While the storing rails 5a are thus positioned at the lowermost position, a cheese 6 is supplied from a storing conveyer 3 to the uppermost rails 5a. On completion of storing all cheeses, the elevating chain 9 is wound up, and the interval with the rails 5b is widened to supply the cheese 6. Thus, the storing conveyer can be installed at the lower position, and a lot of spools can be stored in a narrow space.
