Title: Amplifier circuit
Inventor: KUSAMA NOBORU
IPC: H03F3/26
Filed: 1993-06-02
Abstract: PURPOSE:To obtain an amplifier circuit with high efficiency, high output and high gain by employing NPN hetero junction bipolar transistors(TRs) in a push-pull configuration in which AlGaAs is employed for the emitter and GaAs is employed for its base. CONSTITUTION:Each emitter employs AlGaAs and each base uses GaAs in NPN hetero junction bipolar transistors(TRs) 1, 2. The TRs 1, 2 are used as a common emitter connection and act like a push-pull circuit by input output baluns 11, 12. A reverse breakdown voltage characteristic between the emitter and the base is improved by employing the NPN hetero junction bipolar TRs using AlGaAs whose band gap is larger than that of silicon for its emitter and in which its dose is made smaller than that of the base. Thus, the amplifier circuit with a high efficiency, a high output and a high gain is obtained by forming the TRs as a common emitter push-pull circuit operated at a deep bias.

Title: Insulation type digital analog converter
Inventor: YOSHIDA HIDEKAZU
IPC: H03M1/08
Filed: 1979-12-04
Abstract: PURPOSE:To compensate the deterioration in the performance of insulation transformers, by connecting and transmitting the basic pulse modulating analog signals to a pulse synthesizing device via a pair of insulation trnasformers with modulation waves.

Title: Fuel cell power generating system
Inventor: ISHII AKIKO
IPC: H01M8/04
Filed: 1991-06-27
Abstract: PURPOSE:To achieve compactness of a system by providing a steam generator in an outlet of a deaerator. CONSTITUTION:In a cooling water system IC for a fuel cell 1, cooling water which has absorbed generated thermal energy is introduced in a two-phase flow into a deaerator 3. A pressure detector 20 detects a pressure inside the deaerator 3. Accordingly, a flow rate control valve 21 is regulated, thus controlling a flow rate of steam flowing in a steam generator 4. Accordingly, a steam pressure of the deaerator 3 is controlled at a predetermined value. Namely, a temperature of the cooling water of the system IC for the cell 1 is controlled. The steam generated in the deaerator 3 is introduced through the control valve 21 by the steam generator 4 disposed downstream from an aqueous phase outlet of the deaerator 3, followed by cooling, to be supplied as fuel cell cooling water. A temperature detector 26 detects a temperature in an inlet of the system 1C, thus controlling a flow rate of hot water to a primary-side heat exchanger 4A of the steam generator 4 at a predetermined temperature. Consequently, it is possible to reduce a load exerted on a water treatment device, recover thermal energy of a high quality, and construct a compact plant.

Title: Semiconductor device
Inventor: NAKAMURA AKIRA
IPC: H01L29/786
Filed: 1988-06-24
Abstract: PURPOSE:To form a stable contact and to improve a device in yield by a method wherein a silicon film thick enough is formed only on a region where aluminum of a source and a drain and a contact are formed. CONSTITUTION:Poly-Si 2000Angstrom  in thickness is deposited on a quartz substrate through an LPCVD method, which is subjected to a patterning to leave only a contact region unremoved. A poly-Si 3 is deposited on the whole face for the formation of a channel region, and a pattern is formed so as to leave a poly-Si layer unremoved only on a transistor region. Next, a gate oxide film 4 and a gate electrode poly-Si 5 are formed through a usual process, and P<+> is ion-implanted in a self-aligned manner to form an n-type region. By this ion implantation, an interface between a poly-Si layer 2 of a first layer and the poly-Si layer 3 of a second layer is sufficiently destroyed, so that a good contact can be formed. Therefore, a large gm can be obtained by making the thickness of the poly-Si layer 2 of the channel region small. After the process mentioned above, a semiconductor can be obtained through a conventional process.

Filed: 1984-07-28
Abstract: PURPOSE:To improve detection precision by calculating the center line of a distribution by a method of the least squares as to respective indication values of ultrasonic flaw detection data and calculating the standard deviation of each indication from the center line. CONSTITUTION:The presence of an ultrasonic wave beam C at a reverse wave generation part D along the weld zone A is utilized to calculate the center line F of the distribution by the method of the least squares as to respective indication positions of ultrasonic flaw detection data generated at the reverse wave generation part D and a defect E. Then, the standard deviation sigma1 of each indication from the center line F is calculated to make its large-small decision and thus detect the defect E, so there is no influence upon detection precision even if there is the reverse wave generation part D. Then, the whole part is divided into small parts DELTAX to calculate the standard deviation sigma2 of the indication of each small part DELTAX from a center line (f) and also calculate the difference G between the center line F and center line (f), and further compare the standard deviation sigma1 of the whole with the standard deviation sigma2 of small areas for abnormality decision making, so the detection precision of a defect is further improved.
