Filed: 1990-02-16
Abstract: PURPOSE:To improve the life of a lamp by covering the inside surface of a luminous tube made of quartz glass with a light-transmitting coating film consisting of diamond or diamond-shaped carbon. CONSTITUTION:The inside surface of a luminous tube 21 is coated with diamond or diamond-shaped carbon. Here, carbon C has an extremely high melting point and a bond of C and C is very strong so that reaction of metal halide sealed inside the luminous tube 21 (to the luminous tube made of quartz glass) is prevented, further this coating film 22 is chemically extremely inactive so that the metal halide is not allowed to infiltrate into the coating film 22. Further, diamond or diamond-shaped carbon firmly sticks to the luminous tube 21 consisting of quartz glass so as to be prevented from being separated from the luminous tube 21 and from forcing the coating film 22 to be cracked. Thereby, the life of a metal vapor discharge lamp can be prolonged.

Abstract: PURPOSE:To allow the easy wavelength conversion with a nonlinear crystal between waveguide modes by impressing an electric field to uniformly crystallize the polarization direction of a waveguide part and inverting the electric field to locally heat and rapidly cool a laser beam, thereby locally forming a polarization inverted region. CONSTITUTION:A glass substrate formed with a fine groove and a glass substrate having a flat surface are stuck to each other to form a clad 1 and the end face of the stuck glass substrates is immersed into a molten org. material. After the org. material sufficiently infiltrates into the groove, the substrates are parted from the molten org. material and are slowly cooled to form the waveguide 2 consisting of the crystallized nonlinear org. material in the clad 1, by which the wavelength conversion element is produced. This wavelength conversion element is installed between electrodes 5 and is first subjected to the crystallization uniform in the polarization direction by impressing a downward electric field to the waveguide 2 in the clad 1. The direction of the electric field 6 is then inverted upward and the waveguide 2 is partially irradiated with the converged laser beam 4 and is thereby heated and cooled, by which the polarization inverted region 3 is formed. The periodic structure is formed by scanning the laser beam in the waveguide direction.

Abstract: PROBLEM TO BE SOLVED: To provide a battery device for a vehicle which is capable of quickly discharging the gas generated in a battery cell due to an abnormal state of a battery to the outside from a vehicle, when a fault occurs in a function which monitors the abnormality in the battery. SOLUTION: A battery ECU 6 detects an abnormal; state of a battery, based on voltage data and temperature data and controls a ventilating fan 16 and inside/outside change-over valve 18. In addition, when the ECU 6 detects the occurrence of an abnormality, such as a short circuit of a sensor, etc., where the abnormal state of the battery is unable to detect, the ECU 6 actuates the fan 16 and switches the valve 18 to the outside position. Even if the abnormal state of the battery repeatedly occurs after the monitored abnormal occurrence, the gas generated from a battery can be quickly discharged to the outside from a vehicle.

Title: Gallium-arsenoid semiconductor integrated circuit device
Inventor: MAKINO HIROYUKI
IPC: H01L27/095
Filed: 1990-02-16
Abstract: PURPOSE:To reduce the power voltage dependency of a source couple circuit by clamping the common source of a metallic semiconductor (MES) FET constituting a source couple circuit to a prescribed potential by means of a Schottky diode. CONSTITUTION:Schottky diodes 12, 13 are connected in series between a common source and GND of normally-off type metallic semiconductor (MES) FETs 5, 6. Since the anode-cathode voltage of the Schottky diode is clamped nearly at 0.7V, a node 9 connecting to the two diodes 12, 13 is clamped at nearly -1.4V. When a negative power supply VEE is set to -2.0V, since the potential at the node 9 is set to -1.3V, no clamp effect is expected but when the VEE is lowered, the potential of the node is not lowered less than -1.4V by the clamp effect of the diodes 12, 13. Thus, both the input threshold level and the output threshold level are almost independent of the negative power supply voltage VEE.
