Abstract: PURPOSE:To increase the deposition velocity of a film without deteriorating film quality by forming a recess groove on the surface of an electrode impressed with high-frequency voltage and forming a magnetic field orthogonally crossing to a high-frequency electric field in the recess groove and also directly feeding reaction gas. CONSTITUTION:The inside of a vacuum vessel 1 is adjusted to required gas composition, the flow rate of gas and pressure by means of both a feed mechanism 15 for reaction gas and an exhaust device 2 and high-frequency voltage is impressed to a high frequency impressing electrode 4 to generate glow discharge between it and a grounded electrode 5. At this time, electrons generated in plasma are trapped by a magnetic field orthogonally crossing to a high-frequency electric field which is formed by a magnetic field formation device 12 in a recess groove 11 of the electrode 4 and a plasma region high in electron density is formed in the recess groove 11. Further since reaction gas is directly fed to the inside of the recess groove 11 by a feed mechanism 15, the decomposition efficiency of reaction gas due to plasma is enhanced and a film is high-speedily formed in the part on a base plate 8 wherein the part is opposed to the recess groove 11. Further the distance of the base plate 8 for the plasma region in the recess groove 11 is freely adjusted by transferring the grounded electrode 5 by means of a positioning device 13.

Title: Life estimating method of light emitting diode and light emission drive device provided therewith
Inventor: KOIKE SHIGEAKI
IPC: G11B7/126
Filed: 1995-04-05
Abstract: PURPOSE: To enable the service life of a light emitting diode to be estimated by a method wherein a drive current which enables the diode to emit light of certain output power is made to serve as a reference value, and another drive current n times as large as the above reference value is made to serve as a deterioration threshold value for replacement. CONSTITUTION: A semiconductor laser diode as a light emitting diode deteriorates in output over time and increases in drive current over time of service to output a certain output power, for instance, 20mW. In a laser diode of wavelengths 680 to 800nm, provided that an initial current value I0 (drive current to obtain optical output of 20mW at normal temperature) is made to serve as a reference value, the laser diode deteriorates abruptly in optical output when a drive current is set 1.2 to 1.3 times as large as the reference current value I0 . At that point, the laser diode is 5000 hours or so in service. Therefore, in the case of the above laser diode, a drive current 1.2 times as large as I0 is set as a deterioration threshold current Id .

Abstract: PURPOSE: To improve an SN ratio by sending a signal having noise to an amplitude filter which approaches a quantifying level and enhances amplitude, taking the loss of amplitude that becomes different according to excess or deficiency into consideration to each filter path that is related to each quantitative signal level. CONSTITUTION: When a receiver is received from a transmission path L, it sends a code signal S to a 1st path N0 to recognize a level '0' and to a 2nd path N1 to recognize a level '1'. The N0 and N1 are gains which fall when the amplitude of a signal S moves to be away from the levels upward or downward and consist of nonlinear amplifiers APCi which offer the largest gain on a recognition level (0 or 1) of a path that is included in it. An output signal S1 from the APCi is sent to a relation integrator I1 inside an integrated circuit CI, the integrator sums continuous electric quantity that is received from the APC1, and the quantity is in proportion to various continuous amplitude that is acquired by a signal S1 that exceeds the period of a basic cycle.  The signal S is also sent to an auxiliary circuit CA, and the auxiliary circuit sends reference voltage Vref that is equal to a level '1' in the signal S as a threshold to the APC1.

Title: Manufacture of znsepn junction
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L21/368
Filed: 1980-06-16
Abstract: PURPOSE: To easily obtain a P-N junction by consisting Au as an acceptor in inactive gas wherein the Au is inducted into Z type ZnSe.  
     CONSTITUTION: As a substrate, ZnSe single crystal obtained by temperature differential method liquidus growth controlled Se vapor pressure is used. Bi is intentionally poured in molten Zn to facilitate the following acceptor diffusion or P type in an alloy and heat treatment is applied at 800∼600°C. In including Sn of 5% is placed on the whole surface of the resulting N type crystal and Au is evaporated to the opposite surface. Next, ultrahigh purity Ar is flown into vacuum to maintain the condition at 350∼330°C for about three minutes and the Au is gradually cooled. In this way, forward rising becomes more than 20V when a P-N junction has been formed by consisting the Au as an acceptor and luminescence is performed by forward current. Therefore discrimination is made easy. The Au alloy or Ar gas prevents the evaporation of the Se from the crystal during diffusion and the Au alloy or the Ar gas plays a role preventing the expansion of the shift from stoichiometric composition.

Title: Switching material
Inventor: TAKADA JUN
IPC: G01K11/00
Filed: 1992-02-18
Abstract: PURPOSE:To utilize SrTiO3 for the switching material of a temperature switch, the photo-receiving part of an optical switch, etc., by utilizing a change in photoconductivity based on the phase change of SrTiO3 and by irradiating SrTiO3 with light having a specified range of energy at a temperature below a fixed temperature. CONSTITUTION:SrTiO3 is irradiated with a light having an energy of 3-5eV range at a low temperature below 150K to make its conductivity suddenly change and to make it have a photoconductive spectrum peculiar at a temperature if decided. Photoconductivity changes markedly in a vicinity of a temperature where SrTiO3 develops phase changes; therefore, it can be utilized as the switching material of a temperature switch which detects this temperature. Merely varying the intensity of irradiating light allows production of temperature switches different in detection temperature. Since photoconductive spectrum is determined by fixing temperature, varying temperature allows their utilization for the photo-receiving part of optical switches different in photo-receiving characteristics.
