Title: Optical control element
Inventor: MAEDA YOSHINOBU
IPC: H01S5/00
Filed: 1992-06-15
Abstract: PURPOSE:To optically provide a NOT circuit and make fully optical logical operation possible by controlling the intensity of light transmitted through an optical transmission medium along variation of control light differing in light wavelength. CONSTITUTION:The optical transmission medium 10 has low transmissivity and high transmissivity to light wavelengths lambda1 and lambda2 and transmits light with the light wavelength lambda2 when the light is inputted to turn ON. Further, a light generating element 11 when optically or electrically applied with a control input from outside varies in its generation wavelength from lambda1 to lambda2 or vice versa. Assuming that the oscillation wavelength varies from lambda2 to lambda1 when a semiconductor laser is used as the light generating element 11 and an impressed current is increased, the light intensity of lambda1 becomes larger than the light intensity of lambda2 because of the high impression quantity. When the outputs of respective semiconductor lasers are made incident on the optical transmission medium, there is a case wherein the light output of lambda1 becomes less than that of lambda2 since the light wavelength lambda1 is lower in transmissivity than lambda2, thereby providing the optical NOT circuit.

Abstract: PURPOSE:To switch reception frequencies at a point where two adjacent base stations become equal in level by providing the mobile radio equipment with a circuit which detects the difference in frequency between radio waves from a base station currently in reception and a base station adjoining to the station. CONSTITUTION:An FM type mobile receiver is shown by 15. The frequency difference detecting circuit 16 provided to the mobile receiver 15 as a substitute for the conventional squelch circuit detects the frequency difference between the base station currently in reception and a base station adjoining to the station.

Abstract: PURPOSE:To stably obtain an oxide superconducting wire with the desired fine diameter and high critical current density by preheating a sintered wire with oxide superconductive composition at the temperature of 700 deg.C or above, and locally heating the preheated raw material wire at the temperature of the melting point or above to form a fusion zone. CONSTITUTION:A raw material wire 1 is preheated at the temperature of 700 deg.C or above by the first heating means 9, then it is locally heated at the temperature of the melting point or above by the second heating means 4. The region heated by the second heating means 4 is melted to form a fusion zone 3, and a fused liquid in a pipe 5 arranged in contact with the upper end section of the fusion zone 3 is lifted to the upper end of the pipe 5 by the capillary phenomenon. This fused liquid is raised from the upper end of the pipe 5 and coagulated.

Filed: 1977-12-24
Abstract: PURPOSE: To automatically produce glissando effect tones by performing addition and substraction of key touch information based on the glissando control signals which subsequently addition change up to the specified value.  
     CONSTITUTION: The key code signals at the key touching from a key assigner cause an adder 20 to subsequently add the glissando control pulses, based on the key touch timings up to a specified value, according to the glissando control pulse priods outputted by a shift register 17 via shift register 16. This addition value becomes a carry signal and an adder 23 has the glissando control signals stored in shift register 25a... by each touched key channel, thereby controlling the key-on signals being applied to an adder 58. Hence, the adder 58 which is controlled of addition and subtraction via switch 10d generates the subsequently increasing or decreasing key code signals, which then address frequency information memory. As a result, the glissando tones which subsequently become high and low according to the touched key pitches are automatically formed and the glissando performance may be readily accomplished.
