Title: Manufacture of solar cell and solar cell f0rmed of the same
Inventor: ASAI KUNIO
IPC: H01L31/04
Filed: 1990-04-28
Abstract: PURPOSE:To prevent thermal deterioration and to reduce a cost by simultaneously baking a current collector electrode and an Al film, then forming a pn junction at a light receiving surface, and baking, after the electrode is formed, it. CONSTITUTION:Current collector electrodes are formed of conductive Ag pastes 11, 12 on a light receiving surface and an opposite side thereto, and an Al film 13 is so formed by a vacuum process as to partly expose the electrodes. After the electrodes are formed, the electrodes and the film 13 are simultaneously baked, and a pn junction is formed by a vacuum process at the light receiving surface side. Simultaneously, after the electrodes are formed of the pastes 11, 12, they are baked, a P-type Si substrate 10 formed with the electrodes on both side surfaces is half-dipped to be soldered to the electrode parts. Then, a thermal process may be conducted only once, and ohmic contact, adherence of the film 13 to the electrodes are eliminated by the surface oxide film. Thus, thermal deterioration is eliminated to reduce its cost.

Title: Dryetching process
Inventor: HORIO TAKUJI
IPC: H01L21/3065
Filed: 1985-05-29
Abstract: PURPOSE:To clean up the surface of Si substrate while forming tapers at the step difference parts by a method wherein, before the reactive ion etching process, the surface of Si substrate is shallowly etched by plasma. CONSTITUTION:Oxide film patterns 12 are formed on a single crystal Si substrate 11 with surface (100). Next the substrate 11 is shallowly etched by plasma using the patterns 12 as masks. In other words, when the substrate (100) is vertically patterned in the parallel with OF direction e.g. as shown in the figure, around 5.5 deg. of taper is formed constantly due to dependability of the part below the patterns 12 on the crystalline direction. Besides, the etching process under such conditions can perform undercutting operation so that foreign matters 13 may be removed by lift off operation to clean up the surface of Si substrate 11. Through these procedures, the surface of the substrate can be etched flat with good reproducibility.

Title: Apparatus for production of semiconductor
Inventor: YOSHII SHIGEJI
IPC: H01L21/285
Filed: 1993-05-17
Abstract: PURPOSE:To form metal sputtered films having high quality with a metal sputtering device by providing a transporting chamber with a wafer heating mechanism and removing the moisture of wafer surfaces just prior to sputtering. CONSTITUTION:The surface of the wafer transferred into the transporting chamber 2 is heated to about 200 to 300 deg.C by a heating mechanism 11 mounted on a transporting arm 7. The moisture sticking to the wafer surface is completely evaporated away by the heating treatment, by which the wafer surface is stabilized. The next wafer is subjected to the heating treatment while the previous wafer is subjected to deposition by sputtering and, therefore, the lamp heating is executed by utilizing the time for waiting for the sputtering in spite of the increase in the processes. The increase of the processes is consequently not the factor for an increase in time. Since the heating is by the lamp of a halogen lamp, the adverse influence to be exerted on another parts in the transporting chamber is eliminated. The nonuniform formation of the metal deposited films does not arise any more and the patterning defects decrease.

Title: Active filter
Inventor: AMAMOTO HIDEKI
IPC: H03H11/12
Filed: 1983-06-24
Abstract: PURPOSE:To keep the circuit sensitivity Q to a constant value even if the gain is changed by activating an operational amplifier as a non-inverting amplifier and feeding back its inverting input signal to a CR circuit network via a buffer amplifier of unity gain conducting impedance conversion. CONSTITUTION:An input terminal 11 is connected to a non-inverting input of the operational amplifier 19 through a CR circuit network 12, an output of the operational amplifier 19 is connected to an output terminal 14 and also grounded through a voltage dividing element 25, and the output of the voltage dividing element 25, i.e., a connecting point of resistors 23, 24 is connected to an inverting input of the operational amplifier 19 as feedback. Then, the output of the voltage dividing point is connected to the CR circuit network 12 through a buffer amplifier 26 of the unity gain to be connected to the non-inverting input of the operational amplifier 19 as positive feedback. Since no signal appears between the inverting input and the non-inverting input of the operational amplifier 19, a signal having the same amplitude of the signal voltage between the non-inverting input and ground is generated between the inverting input and ground. That is, the circuit sensitivity Q is kept constant even if the gain is changed.

Title: Converter circuit
Inventor: SATO KAZUO
IPC: H02M7/155
Filed: 1993-05-17
Abstract: PURPOSE:To build up a power supply stably even when a single-phase AC power supply is used and prevent power elements from being destroyed by a rush current when the AC power supply is interrupted momentarily and is recovered, by building up the power supply through igniting a thyristor at successively increased voltage values every period of a single-phase or three-phase AC power supply cycle. CONSTITUTION:An AC input power supply R-N is inputted to a thyristor 1, and is converted into a DC P-N. An A/D converter 4 A/D-converts the input voltage R-N and the output voltage P-N respectively, and outputs the converted values to a CPU 3. By the outputs of the A/D converter 4, the CPU 3 decides whether the input power supply R-N is a three-phase AC or a single-phase AC, and based on the decision thereof, the CPU 3 so ignites the thyristor 1 that its igniting voltage value is increased in succession from a low value to a high value every period of a power supply cycle. Thereby, the sure build-up of the power supply can be obtained in a short time even when the input power supply is interrupted momentarily and is recovered, a rush current can be suppressed.

IPC: C22B9/187
Filed: 1978-09-20
Abstract: PURPOSE: To prevent occurrences of non-melting zone, by connecting the preceeding electrode and succeeding electrode in one body with screws applied to the ends of electrodes.  
     CONSTITUTION: For example, internal thread 3 is installed at the connecting section of preceeding electrode 1 and external thread 3' is installed at the connecting zone of succeeding electrode 2, and both electrodes 1 and 2 are connected each other with the threads. The outer surface of preceeding electrode 1 is tapered towards succeeding electrode 2 so that tapered portion 7 may be formed. By using this consumable electrode for melting electro-slag, non-melting zone does not occur and both electrodes 1 and 2 melt at the same speed, when molting is in progress and both electrodes 1 and 2 melt at the same time at the connecting zone, because tapered section 7 is small in diameter. The shape of electrode end becomes balanced one and ingots having excellent quality can be obtained.

Filed: 1995-05-15
Abstract: PURPOSE: To make both recording layers possible to well execute recording and reproducing of information by providing an optical disk with a polarizing layer between its first recording layer and second recording layer. CONSTITUTION: The optical disk 8 is formed by successively laminating, from below to above, that is, in the incident direction of rays, a first base material 2, a first recording layer 9, an intermediate layer 10, a dichroic polarizing plate 11 which is the polarizing layer, a second base material 12, a second recording layer 13 and protective layer 6. Accordingly, the generation of the reflected light from the second recording layer 13 as a noise in the reflected light of the first reflection layer is prevented because the rays for scanning the first recording layer 9 do not arrive at the second recording layer 13 if the rays are polarized in the direction where the rays do not transmit the polarizing layer 11 by providing the optical disk with the polarizing layer 11 between the first recording layer 9 and the second recording layer 13.  The focus is thereby well locked at the first recording layer 9 and the good execution of the recording and reproducing of the information is made possible.
