Title: Pwm control converter parallel operation system
Inventor: TEZUKA YASURO
IPC: G05F1/56
Filed: 1990-07-27
Abstract: PURPOSE:To easily share a load, disperse heat and to improve reliability by inputting an ON duty signal from a drive transformer, rectifying, smoothing it, comparing this average terminating voltage with an average terminating voltage from a second converter, and providing a feedback circuit for inputting a reference voltage becoming minimum to an output error amplifier. CONSTITUTION:An ON duty signal from a comparator 9 is input from a drive transformer 2-3 to an ON duty rectifying and smoothing circuit 10. A comparison voltage generator 16 inputs its ON duty average terminating voltage to the inverting input terminal of an ON duty voltage comparator 3. An ON duty average terminating voltage of other parallel comparator is input to a noninverting input terminal. The comparator 3 so controls that the output becomes minimum at the ON duty voltage difference, and inputs it to the noninverting side input terminal of an output error amplifier 8 of an output voltage regulator 16. A reference voltage signal due to the ON duty voltage difference is fed back by the amplifier 8.

Title: Photo trigger thyristor
Inventor: NIWAYAMA KAZUHIKO
IPC: H01L31/111
Filed: 1981-12-11
Abstract: PURPOSE:To obtain a photo trigger thyristor which has no erroneous firing without decreasing trigger sensitivity by leading a trigger current terminal from the cathode electrode of an auxiliary SCR and flowing the trigger current at the forcibly firing time. CONSTITUTION:A trigger current terminal 14 is led from the cathode electrode 9 of an auxiliary SCRC in the SCR of the structure similar to the conventional one. When the trigger current terminal is led from the cathode electrode 11 of the second auxiliary SCRd, a large current is improperly required for firing. When the trigger current is flowed to the terminal 14 at the forcibly firing time, the firing can be performed at the suitable magnitude of about several A, thereby preventing erroneous firing and facilitating the firing at the necessary time. Since the photodetecting area of the photodetector is not defected, the phototrigger sensitivity is not decreased.

Abstract: PROBLEM TO BE SOLVED: To enable high-accuracy compensation with the table memory of small capacity and an arithmetic logic in small scale, in the case of compensating the nonlinear distortion of a power amplifier through a predistortion method. SOLUTION: In polynomial arithmetic parts 21 and 22, amplitudes Vi and Vq of baseband signals I and Q from roll-off filters 11 and 12 are respectively substituted to a polynomial g (v) for amplitude distortion compensation, and the arithmetic results g (Vi) and g(Vq) are calculated. A square arithmetic part 23 calculates an arithmetic output Miq2 expressed as Miq2=(g(Vi))2+(g(Vq)2. Corresponding to this arithmetic output Miq2, a phase value θ in one- to-one correspondence with the arithmetic output Miq2 is read out of a table 24 for phase distortion compensation. Synthetic arithmetic parts 25 and 26 calculate baseband signals I' and Q', which are expressed as I'=g(Vi)×cosθ-g(Vq)×sinθ and Q'=g(Vq)×cosθ+g(Vi)×sinθ.

IPC: G11B7/00
Filed: 1990-07-31
Abstract: PURPOSE:To prevent the external stray dust from sticking to an optical head part and an optical disk part by separating a 1st chamber including the optical head part from a 2nd chamber including an optical disk circuit part by means of a shielding plate and closing up the 1st chamber in order to prevent a cooling air flow from entering the 1st chamber. CONSTITUTION:The inside of an optical disk device is divided into at least a 1st chamber including an optical head part and a 2nd chamber including an optical disk circuit part 4 by means of the shielding plates 8 and 16. Then a 1st chamber is closed up so that a cooling air flow of the 2nd chamber does not enter the 1st chamber. In other words, an optical disk device 15 is divided into a 2nd chamber (cooling part) where the outside air is circulating and a 1st chamber (non-cooling part) where no outside air is circulating in terms of mechanism. Then the heating parts are concentrated in the 2nd chamber and at the same time the 1st chamber is closed up to contain only such parts that with do with the natural cooling. Thus the outside air is supplied to the 2nd chamber to cool it as necessary. Meanwhile the outside air is not substantially circulated in the 1st chamber. Thus the influence of the external stray dust is minimized.
