Title: Removing mechanism of reed screen from reed screen frame
Inventor: ISAYAMA MITSUO
IPC: A23L17/60
Filed: 1982-04-21
Abstract: PURPOSE:To automate the removing operation of a reed screen from a reed screen frame, by changing the reed screen under tension mechanically into a relaxed state, and dropping the reed screen downward. CONSTITUTION:The ends of a reed screen (M) are engaged with protruding parts (N-1) of partition levers (n) in a reed screen frame (N), and transferred to a position where the engaging parts of the protruding parts (N-1) are just under fingers (5-1) and (5'-1) of pushing levers 5 and 5' left and right. At this time, a guide frame 2 is lowerd. The top ends of the left and right pushing levers 5 and 5' are slidden downward by the urging of springs 7 and 7' to bring rolls (a) and (a') into the pressure contact with guide sides 3 and 3' left and right. The pushing levers 5 and 5' are rotated on the sliding fulcrums 6 and 6' to oprate the fingers (5-1) and (5'-1) to the center. Thus, the fingers (5-1) and (5'-1) are inserted between reed screen levers (m) of the reed screen (M) to come near the direction of the protruding parts (N-1). The reed screen under tension is then changed into a relaxed state, easily removed from the protruding parts (N-1) and dropped downward.

Title: Stabilized power source device
Inventor: UIRIAMU ERU HIYUUHESU
IPC: H02M3/28
Filed: 1982-04-22
Abstract: PURPOSE:To obtain frequency responding characteristics of wider band width under all operational conditions, by controlling the electric current flowing into a control winding with a driving circuit. CONSTITUTION:A voltage lamp generator containing differential amplifiers U1 and U3 operates as a pulse width modulator, and periodically impresses voltage pulses which vary along with differences between a detection output voltage VR and a controlling voltage VC of the secondary winding 16 of an output transformer T upon a control winding LCA. The rectangular voltage pulse which is impressed upon the winding LCA and whose width varies, is synchronized to the chopping of a chopper circuit 10 and the pulse generating time varies depending upon the time where the VC and VR intersect. Therefore, since the voltage pulse has a frequency which is different from the chopper frequency, and the pulse source of the product of voltage and time depending upon the difference between the VR and VC is used as a controlling voltage, and the necessity of connecting condensers to the windings LCA and LCB is eliminated, responding characteristics of wider band width are obtained.

Title: Epitaxial wafer
Inventor: SAWADA MINORU
IPC: H01L29/778
Filed: 1989-03-20
Abstract: PURPOSE:To obtain an epitaxial layer wherein electron mobility is large and two-dimensional electron gas concentration is high, by making the In composition ratio (x) of a non-doped In Ga1-xAs layer on the non-doped AlyGa1-yAs layer side larger than (x) on the non-doped GaAs layer side. CONSTITUTION:It is noted that current does not flow in the whole part of an InxGa1-xAs layer 3 at the time of operation, but flows on an InGaAs side in the vicinity of an interface between an AlyGa1-yAs layer 4 and the InxGa1-xAs layer 3. Hence In composition ratio (x), in the vicinity of the interface where the current actually flows, is made large, and the In composition ratio (x) is made small in the part where the current hardly flows. By making the In composition ratio (x) large in the vicinity of the interface, electron mobility and two-dimensional electron gas concentration can be improved. By making the In composition ratio (x) small in the part where the current hardly flows, the lattice mismatching between the InxGa1-xAs layer 3 and the GaAs layer 2 or the AlyGa1-y As layer 4 can be restrained. Thereby the electron mobility is improved, and the two-dimensional electron gas concentration is increased.
