Title: Preparation of amorphous silicon solar battery
Inventor: KUBOI OSAMU
IPC: H01L31/04
Filed: 1981-09-28
Abstract: PURPOSE:To deposite a thin amorphous Si on the substrate and obtain a high performance solar battery by capacitor coupling the ring-shaped electrodes, keeping substrate at a temperature of 200 deg.C or less by separating it from them and generating grow discharge plasma by keeping the concentration of SiH4 to 5% or less. CONSTITUTION:A pair of ring-shaped electrodes 1 are capacitively coupled and the substrate 2 is arranged within the adequate distance. In case the electrode of this kind is used, impact on the amorphous Si film by plasma is less and plasma system can easily be kept pure. In addition, for example, the concentration of SiH5 diluted by H2 is kept at 5% or less. The inner conductor of high frequency coaxial cable is connected to the upper electrode which is far from the substrate 2, while the outer conductor to the lower electrode, and the grow discharge plasma is generated within the cylindrical furnace 4 consisting of quartz and thereby the amorphous Si is stacked on the substrate 2 kept at 200 deg.C or less. According to this structure, a very high open voltage can be obtained, photo- electric conversion efficiency can be improved drastically and consumption of expensive SiH4 gas can be fantastically saved.

Title: Semiconductor laser
Inventor: ABE YUJI
IPC: H01S5/00
Filed: 1985-07-09
Abstract: PURPOSE:To limit a light-emitting region, to improve the reflection efficiency of beams and to lower threshold currents by manufacturing a semiconductor laser through impurity diffusion, through which the type of a semiconductor is inverted, and forming a diffraction grating for distributed feedback to the semiconductor laser so as to vertically operate to a substrate. CONSTITUTION:When a forward bias is applied between a P electrode 7 and an N electrode 9, currents flow through a P-N junction section shaped by a P<+> diffusion region 8, and light is emitted, but currents concentrate to the region of an N-GaAs active layer 3 by the difference of the diffusion potential of GaAs and AlGaAs, thus efficiently generating light emission in a light-emitting region 11 near by the N electrode 9 of a P-N junction section formed to the active layer 3. Beams generated are affected by a diffraction grating 10 positioned near the light-emitting region 11, and only beams having a wavelength satisfying the conditions of the Bragg reflection repeat reflection in the direction vertical to a substrate, and oscillate in a short time, thus emitting light from the surface.

Filed: 1979-11-24
Abstract: PURPOSE: To permit oil hydraulic motor speed change by providing a change-over valve plate for connecting and disconnecting a plurality of communication passages between a distributing valve and a fluid pressure converting section.  
     CONSTITUTION: A change-over valve plate 18 for connecting and disconnecting communication passages 15b is provided between stationary plates 16 and 17 respectively connected to a distributing valve and a fluid pressure converting section. When the change-over valve plate 18 is held at the illustrated position, the communication passages between the distributing valve and fluid pressure converting section are all connected, and thus the oil hydraulic motor is rotated at low speed to provide high torque. When the change-over valve plate 18 is switched over to its upper position, three communication passages are disconnected to leave only six inter-gear gaps in the fluid pressure converting section for converting the fluid pressure into the rotational force. Therefore, the oil hydraulic motor is rotated at high speed to provide low torque.

Title: Coupling element for neural circuit device
Inventor: FURUYA KIYOHIRO
IPC: G06N3/063
Filed: 1989-06-15
Abstract: PURPOSE:To attain the reduction of a chip area by adding a means to a coupling element to compare the present degree of coupling with the intensity of a 1st signal together with a means which writes a new degree of coupling when the coincidence is secured with the comparing means. CONSTITUTION:A staircase wave generating circuit 5 produces a staircase wave S of the n-th stage at an n-th cycle of a clock phiCL. At the same time, a write voltage generating circuit 4 produces the new write voltage P1 corresponding to the potential of the wave S. Then a sense amplifier consisting of transistors 15, 16, 23 and 24 compares the potential of a nodal point N2 of a coupling element W11 with the wave S which successively increases. When it is desired to change a degree of coupling corresponding to the potential VP of a capacitor 26 to that corresponding to f(VP), the potential of a signal P1 of the wave S of the m-th stage is set at (f(mDELTAV) + VTH) when the step of the wave S is set at DELTAV. Thus a new degree of coupling is written into a capacitor 25. As a result, the area of the coupling element is reduced together with reduction of a chip area compared with a case where a counter, etc., are used.
