Title: Optical amplification device
Inventor: INOUE YASUSHI
IPC: G02F1/35
Filed: 1990-09-03
Abstract: PURPOSE:To offer a high-gain, low-noise device which can reduce the intensity of ASE light generated in an optical fiber by inserting a fiber coupler type optical filter or Mach-Zehnder type optical filter which transmits only signal light and exciting light. CONSTITUTION:The signal light S and the exciting light P from an exciting light source 2 are multiplexed by an optical multiplexer 3 and made incident on one end of a rare-earth-element added optical fiber 1a. The exciting light P of the incident multiplexed light excites rare earth element erbium in the optical fiber 1a to form an inverted distribution and the optical fiber 1a functions as an amplifying medium to amplify the signal light S with a specific gain. At this time, the ASE light is generated simultaneously with the amplification of the signal light S. The ASE light, signal light S, and exciting light P are made incident on the fiber coupler type optical filter 4, which transmits only the signal light S of 1.552mu in wavelength and the exciting light P of 1.484mu, but interrupts the ASE light whose wavelength is 1.535mu or nearly equal to the wavelength. Only the signal light S and exciting light P are therefore guided to an optical fiber 1b.

Filed: 1988-09-16
Abstract: PURPOSE:To make it possible to use an airconditioner with reliability, by allowing a display means to index the lapse of time required from the present room temperature to a preset room temperature or the operating status up to the preset room temperature from the start of operation. CONSTITUTION:Preset temperature arrival time indicators 12 and 13 comprise LED of seven segments and the like, and indicate time index required until a room temperature has reached a preset value. For example, when an operation change over slide switch 2 is set to cooling at a room temperature of 30 deg.C, and a room temperature setting slide switch 1 is set to 26 deg.C, then cooling operation is carried out, the temperature of the room under airconditioning is gradually lowered by a compressor 9 and a ventilation fan 8. The temperature and humidity at that time are detected by a temperature sensor 10 or a humidity sensor 11. The thus detected values are stored in a microcomputer A. As a result, indicators 4, 5, and 6, which indicate a temperature difference between the preset room temperature and the room temperature, and the time index indicators are lit up.

Title: Method and head for electrostatic recording
Inventor: NAGASE YUKIO
IPC: G03G15/05
Filed: 1984-11-07
Abstract: PURPOSE:To reduce the corrosion and consumption of electrodes and the deterioration of dielectric materials by a method in which an exciting electrode is set in the force of a discharge electrode with interposition of a dielectric material, the other discharge electrode is connected in proximity to the discharge electrode, and AC voltage is applied between the exciting electrode and the other discharge electrode to generate discharge ion beween both the discharge electrodes. CONSTITUTION:In an electrostatic recording head 1 having a dielectric material 2, a discharge electrode 3, an exciting electrode 4, and an insulator layer 5, the electrode 4 is provided in the face of the electrode 3, but not for the other portion. The electrode 4 is directly con nected to the electrode 3 on the other side through an exciting voltage power source 6. In electrostatic recording for a charge-holder 7a, ions generated in the electrode 3 are extracted to the holder 7a by external electric field by application of bias voltage by a bias voltage power source 8 to between the electrode 3 and an earthed counter electrode 7b set on the back on the holer 7a. Since the discharge current flowing between the discharge electrodes is limited by charge stored in a condenser between the electrode 4 and the electrode 3, the consumption of the electrode by high electric current caused by spark discharge is negligible. Since discharge occurs between the electrodes 3, trouble with dielectric breakdown by deteriora tion of dielectric material can be eliminated.
