Title: Aging method for cathode-ray tube
Inventor: INOUE KATSUYOSHI
IPC: H01J9/44
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent deteriorations of emission characteristics and withstand voltage characteristics by applying a voltage to a first grid next to a cathode for a time longer than applied to the other grids adjacent to the first grid, when degassing aging is performed by applying prescribed voltages to a heater and to the respective electrodes. SOLUTION: In each stage of aging, when voltages are applied to electrodes, the application of a voltage to a first grid G1 is made earlier than for the other grids, and when the application of the voltages is stopped, the application of the voltage to the first grid G1 is stopped later than for the other grids. This prevents the deterioration of emission characteristics due to damage and breakage of an electron emitting layer of an oxide cathode, even if spark discharge occurs during aging. Also, deterioration of withstand voltage characteristics can be prevented, caused by oxides scattered by impacts of the spark discharge and deposited on electrodes, etc. Therefore, high quality is obtained and reliability can be enhanced.

Abstract: PURPOSE:To drive it without prolonging a write time by providing an interval when all pixels are made an anti-ferroelectric state simultaneously at every rewrite of the pixel and making a pulse width selecting the non-ferroelectric state equal to the pulse width selecting a ferroelectric state. CONSTITUTION:When a drive waveform selecting an ON state is impressed to respective pixels, since the value of voltage of a first phase in a first frame is 0V, an OFF state (non-ferroelectric state) is reset, and since the voltage of a second phase exceeds a threshold value voltage value switching to the ferroelectric state, the ON state (ferroelectric state) is set. When the drive waveform selecting the OFF state is impressed to respective pixels, since the first phase voltage in a selection period is 0V, the OFF state is reset.

Title: Apparatus and method for sensing of abnormal operation in side collision alarm system of vehicle
Inventor: KIN SAISHU
IPC: B60R21/34
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To sense the abnormal operation of an ultrasonic sensor without adding a component by a method wherein two kinds of reference voltage waveforms are generated alternately at constant time intervals by one reference voltage generator. SOLUTION: When an ultrasonic sensor is disconnected, an exciting waveform from a point of time T2 to a point of time T3 in Fig. (a) does not exist. Consequently, a detection received signal becomes a waveform as shown in Fig. (c), and it is input to the inverting terminal of a comparator. On the other hand, by means of a microprocessor, a reference voltage generator inputs a waveform whose time is shorter than that of a reference voltage waveform from a point of time T1 to a point of time T4 and which is a waveform from the point of time T1 to the point of time T2 in Fig. (b) is input to the noninverting terminal of the comparator at constant time intervals. At this time, when the output waveform of the comparator at the point of time T3 is in a low-level state as shown in Fig. (e), it is judged that the exciting waveform exists normally.  However, when the output waveform at the point of time T3 is in a high-level state as shown in Fig. (d), it is judged that the exciting waveform does not exist and that the sensor is not operated normally, and an alarm is issued. Consequently, the abnormal operation of a system can be sensed without adding a component.

Abstract: PROBLEM TO BE SOLVED: To reduce production and maintenance costs and to demonstrate an enough sewage purification capacity stably by using sewage flowing convectively with a fluidized carrier by an oxygen-containing gas supplied from a diffusion pipe and transferring solids in the inner bottom part of a precipitation chamber to an aeration chamber. SOLUTION: Sewage is introduced into an anaerobic chamber 6, and by supplying air from a diffusion pipe 8, a fluidized carrier 7 supporting aerobic bacteria on its surface is made to flow vertically in convection with the sewage by the air in an aeration chamber 4. In the anaerobic chamber 6 and the aeration chamber 4, the sewage flowing convectively is used, the sewage in the chamber 6 is transferred to the chamber 4 through one communication opening 2a. During the transfer, the outflow of the fluidized carrier 7 is hindered, and the inflow of scum into the chamber 4 is hindered by a baffle 14. Since the fluidized carrier 7 is made to flow vertically in convection with the sewage, the lowering of a purification capacity by the clogging of a filter material can be eliminated.
