Title: Ion laser device
Inventor: TAKAHASHI NORIO
IPC: H01S3/22
Filed: 1982-04-27
Abstract: PURPOSE:To enable to obtain a laser output stable for a long time, by connecting heating type getters in parallel with a thermal cathode of a laser tube. CONSTITUTION:The laser tube 1 is constituted of anodes 5, the cathode 7, an output mirror 3, and a total reflection mirror 4, which is oscillated in laser by a photoresonator and outputs a laser light 10. In this laser tube 1, the heating type getters 9 are connected in parallel with the cathode 7, and the cathode 7 and the getters are operated by heating simultaeously by a laser power supply. Thereby, the impurity gas in the laser tube 1 is absorbed by the getters 9, thus the deterioration of the group of graphite discs and that of the cathode are prevented, and therefore a power output stable for a long time can be obtained with no contaminations of optical windows 2 and 2' and less deterioration of the cathode.

Abstract: PURPOSE:To improve the frequency characteristic of an output signal and to reduce the power consumption of the output circuit by converting a level of a signal inputted from one of plural circuits with different voltage level into a level of other circuit, outputting an output signal from a control series circuit having a load element and inputting the output signal to an output series circuit as a control signal.

When the frequency division signal f0/N is led more than the reference signal fr, a phase lead signal is brought into an H level and a phase lag signal is brought into an L level and they are outputted. Moreover, when the frequency division signal f0/N is lagged more than the reference signal fr, the phase lead signal is brought into an H level and the phase lag signal is brought into an H level and they are outputted. Furthermore, when the frequency division signal f0/N is coincident with the reference signal fr, both the phase lead signal and the phase lag signal are brought into an H level and they are outputted.

When the air stream A is caused to flow within the duct, the airstream A flows in a state of a speed curve S1 wherein a flow speed S1 is maximum at the central part and is gradually decreased as it goes to both sides to speeds S2 and S3 due to the frictional effect of the duct wall surface and the airstream. When the airstream A is divided into W1>W2>W3<W4<W5 among branch flows of respective fins, and the flow quantities per unit time are made substantially equal, and the blow-off port sections are also made substantially equal. Hence, airstream blown off from respective fins show substantially uniform flow speeds.

Title: Charger for secondary battery
Inventor: KANEKO SHIGEHIRO
IPC: H02J7/04
Filed: 1991-04-04
Abstract: PURPOSE:To prevent charging time for a secondary battery from being unreasonably lengthened while a memory effect of the secondary battery can be effectively eliminated and suppressed. CONSTITUTION:In the case of mounting a secondary battery 2 to a battery terminal 9, terminal voltage of the secondary battery 2 is measured prior to charging. In the case of the terminal voltage in a fixed range in the vicinity of final voltage of the secondary battery 2, a discharge limiting switch 16 is turned on to perform a forced discharge of the secondary battery 2 prior to the charging. The charging is started first when the terminal voltage is decreased surely lower than the final voltage. In the case of the detected terminal voltage out of the above-mentioned range, the charging is instantaneously started. Since the forced discharge of the secondary battery is automatically performed at an adequate period, a memory effect is effectively eliminated and suppressed.
