Abstract: PURPOSE:To achieve a uniform carrier distribution on an activation layer and an efficient current injection by forming each conductive-type impurities area penetrating the activation layer selectively from both the left and right sides and forming a p-n junction in reference to an activation area making higher a conductivity of one clad layer. CONSTITUTION:After a semiconductor laser device forms a high-resistance AlGaAs layer 4 on a semi-insulating(SI) GaAs substrate 10, it forms a P-AlGaAs clad layer 3, a multiple-quantum well, namely a MQW activation layer 2, and an n-Al GaAs clad layer 1 in sequence. Then, a p-type impurities ion impregnation area 20 and an n-type impurities ion implantation area 21 are formed on these by the ion implantation method, respectively. The edge of an n-type impurities implantation area 21 and that of a p-type impurities implantation area 20 within an n-AlGaAs layer 3 are in AlGaAs junction with a high potential barrier, nearly no current flows, current flows through a p-n junction around the activation layer 2 with lower potential barrier than it, and carriers (in this case, electron) are injected into this activation layer 2. Thus, distribution of the carriers injected into this activation layer 2 becomes nearly uniform, thus achieving an efficient injection.

Raw material, which is charged in the shrinking casing 13 by an amount in proportion to the capacity of the shrinking casing 13, is rollingly advanced while being heated in the shrinking casing 13 and gradually softened and at the same time turned to be a lump with smaller volume and higher density due to the deaeration of foamed polystyrene in order to be discharged from the rear end of the shrinking casing 13. Accordingly, when the capacity of the shrinking casing 13 is set in accordance with the amount to dispose, the low cost disposal can be realized without producing the piling-up of scrap. If two or more machines are made into series by connecting two or more shrinking casings 13, the disposal power can be increased by the two times or more.

Title: Video signal recorder
Inventor: YOKOYAMA EIICHI
IPC: H04N5/765
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To inexpensively constitute a monitoring video system by recording a video signal at every prescribed time before the change of picture is detected and recording the signal continuously after detected. SOLUTION: A system control circuit 3 detects the change of the picture from the detection signals of sensors 9-1 to 9-n and the video signal SV outputted from a monitoring video camera 1. A data compression processing circuit 5 data-compresses the video signal for one screen, which is extracted from the video signal SV at every prescribed time, so as to supply it to an HD Drive 7 until the change of the picture is detected by the system control circuit 3. Then, the signal is sequentially recorded on a hard disk as a ring buffer. VCR 2 continuously records the video signal SV after the change of the picture is detected in the system control circuit 3. VCR 2 records the video signal SV for prescribed time and it stops. Then, it returns to a state where the video signal SV is recorded in the hard disk at every prescribed time as mentioned above, for example.  Thus, the monitoring video system can be constituted without necessitating expensive VCR having an intermittent recording function for recording the video signal into a magnetic tape for long time.

Title: Electrostatic accumulation type resistance welding machine
Inventor: YOSHIMOTO KOUICHI
IPC: B23K11/26
Filed: 1982-11-25
Abstract: PURPOSE:To reduce the size of a welding transformer and to control easily the waveform of secondary current by performing intermittently the discharge from a capacitor. CONSTITUTION:A transistor 6 for discharge is provided to a discharge circuit, and the dischrge from a capacitor 3 is intermittently performed by utilizing the switching characteristic of the TR so that the charge is impressed intermittently to a welding transformer. More specifically, the energy accumulated once in the capacitor 3 is released intermittently by the TR6. The DC excitation current of a welding transformer can be limited and the wave of primary discharge current can be controlled by changing the period of the intermission as well as the conducting time and number of conduction. When the DC excitation current is thus limited, the need for increasing the sectional area as with a conventional welding transformer is eliminated.

Title: Viscosity measuring apparatus
Inventor: MURAMATSU HIROSHI
IPC: G01N11/16
Filed: 1987-08-19
Abstract: PURPOSE:To enable measurement of viscosity of a small amount of a liquid sample, by placing a sample liquid into a cell to measure an oscillation frequency of a crystal resonator in contact therewith. CONSTITUTION:A crystal resonator 1 is a device utilizing piezoelectric effect and is connected to an oscillation circuit 4 through a cell 2 to cause a mechanical vibration. Though very small, the vibration causes a shearing stress between the surface of a liquid and the resonator 1 in contact with the liquid and the force thereof balances a force with the vibration of the resonator 1 as elastic body. Hence, a difference between an oscillation frequency when a liquid does not exist and that when the liquid gets in contact with the resonator is in a logarithmic relationship with viscosity. Thus, the viscosity of a sample liquid can be measured from a calibration curve predetermined by obtaining a value of the oscillation frequency.
