Title: Gas replenishing method for excimer laser device
Inventor: MIZOGUCHI KAZU
IPC: H01S3/036
Filed: 1992-11-30
Abstract: PURPOSE:To make it hard for the optimum compositional ratio of gas to break even when a gas replenishing operation is repeated by a method wherein, when halogen gas, which is diluted by buffer gas, is replenished, the gas evacuation process, to be conducted to constantly maintain the gas pressure in a laser chamber, is omitted. CONSTITUTION:The replenishing point of time of gas is set at the point of time when the laser oscillation pulse number Pn reaches the prescribed threshold value Pc, and the evacuation process, to be conducted to constantly maintain the entire gas pressure when gas is replenished, is intentionally dispensed with. To be more precise, the laser oscillation pulse P, outputted by a pulse monitor 20, is detected, the detected pulse P is inputted to a controller 15, and the replenishing time of gas is determined using the above-mentioned laser oscillation pulse P. Also, the operation pulse number Pe per unit time is detected, and the replenishing quantity of diluted halogen gas may be controlled in such a manner that it is proportioned to the computed oscillation speed. As a result, the entire gas pressure goes up, but the laser output can be made small by the dilution of the dilute gas component per unit cubic value.

Title: Polarization dispersion compensating method
Inventor: ONO TAKASHI
IPC: H04B10/2507
Filed: 1993-12-20
Abstract: PURPOSE:To provide a polarization dispersion compensating method which suppress the degradation in waveform due to polarization dispersion of a transmission line in an optical communication system. CONSTITUTION:Signal light 2 subjected to optical frequency modulation to a frequency f0 is made incident on an optical fiber 8. In the exit end of the optical fiber 8, signallight 2 is separated into two orthogonal polarized waves by a polarized wave separating element 13 after passing a polarization control element 9 and a polarization maintaining fiber 10. Separated polarized signal light 2 is received by a balanced light receiver and is converted into an electric signal, and an intensity signal 18 of the component of the frequency f0 out of this signal is detected. The polarization control element 9 is so controlled that this intensity signal 18 is always minimum. Polarization dispersion of the optical fiber and that of the polarization maintaining fiber 10 are cancelled by each other by this polarization control, and the degradation in waveform due to polarization dispersion is suppressed.

Title: Electronic unit
Inventor: OSHIMA SATOHARU
IPC: G06F12/16
Filed: 1992-11-30
Abstract: PURPOSE:To prevent the unnecessary consumption of a battery by executing feeding from the backup battery to RAM after prescribed time elapses when feeding from a commercial power source is stopped. CONSTITUTION:When feeding from an AC power source to a main power source means 20 stops, a detection means detects it and outputs it. The main power source means 20 maintains feeding to a control means and a memory means for prescribed maintaining time even when feeding from the AC power source is stopped. Since a switching means starts feeding from an auxiliary power source means to the memory means from when it receives output from the detection means within the maintaining time, feeding from the auxiliary power source means to the control means and the memory means becomes unnecessary till then and the power consumption of the auxiliary power source means is reduced. Thus, the consumption voltage of the auxiliary power source means for backup is saved since the main power source means and the auxiliary power source means for backup are efficiently switched and feeding to an electronic unit and the memory means is executed.

Title: Power consumption controller
Inventor: ARAI SATOSHI
IPC: G06F1/26
Filed: 1990-11-27
Abstract: PURPOSE:To suppress unnecessary power consumption by providing a sensor to detect whether a worker is in front of electronic equipment or not and power- controlling by making display off automatically, for instance when the worker is not in front of the electronic equipment. CONSTITUTION:When a worker leaves his seat during personal computer operating, a sensor 1 detects that the worker leaves, and sensor status becomes '0'. Thus, a signal inputted to a switch 11 of a back light power is changed from '1' into '0', the switch 11 of the back light power becomes off with receiving it, the power is not supplied to a back light and the back light is out. After this, when the worker comes back, the sensor status becomes '1' and the signal inputted to the switch 11 of the back light power is changed from '0' into '1', the switch becomes on, the power is supplied to the back light and the back light is on. Thus, unnecessary power consumption while the worker is absent is avoided.

Title: Method and device for dealing with power interruption
Inventor: NAKAMURA MITSUO
IPC: H02H3/24
Filed: 1990-11-27
Abstract: PURPOSE:To operate a DC-DC converter during an interval after occurrence of power interruption before provision of an undervoltage alarm by suppressing production of the undervoltage alarm upon detection of power interruption and suppressing production of a power interruption signal until detection of undervoltage thereby making possible to produce the undervoltage alarm upon recovery of power. CONSTITUTION:Upon elapse of a predetermined time after power interruption, a power interruption detecting circuit 21 detects power interruption to produce a high level output signal B which is fed through an inverter 23b to an AND circuit 23a. Consequently, production of an UVA signal for externally alarming power interruption is inhibited thus realizing a normal operation with respect to the outside. When the voltage drops furthermore due to sustained power interruption and the undervoltage detecting circuit 21 detects an undervoltage close to an alarm limit for producing a high level output signal A, an AND circuit 23c produces a power interruption signal to externally alarm power interruption.

CONSTITUTION:For a composite film or composite sheet for which an outer layer 1, an intermediate layer 2 and an inner layer 3 are integrally formed, a rust-preventive agent is not contained in the outer layer 1. In the case of the same type of material, the density of the outer layer 1 is made larger, and the thickness is made thinner comparing with the inner layer 3, and in the case of a different type of material, the outer layer 1 is formed by a material with a smaller gas permeability in order to block the dispersion of a rust-preventive agent as much as possible, and let the dispersion head toward the inner layer. The content of the rust-preventive agent is made larger for the intermediate layer 2. For this reason, the thickness is preferably made as thick as possible. The inner layer 3 may container the rust-preventive agent. When the rust-preventive material is formed by a 2-layer structure, it consists of an outer layer and an inner layer, and the rust-preventive agent permeation of the outer layer is kept to its minimum. The rust-preventive agent is contained by the inner layer, and the volatile rust-preventive agent is made to head to the inside direction.
