Title: Optical information recording and reproducing disk
Inventor: OOTA TAKEO
IPC: G11B7/2433
Filed: 1985-06-07
Abstract: PURPOSE:To facilitate the control of the sensitivity and weatherability of the title disk and to enable the large-capacity recording and high-speed access by incorporating an additive material having electronegativity specifically related to a reducing metallic oxide contg. into the thin film consisting essentially of the metallic oxide. CONSTITUTION:In a medium for recording information which is heated by the irradia tion of laser light, etc., and hence whose state is changed by the absorbed energy, M2 is incorporated as an additive material into a film consisting essentially of a reducing metallic oxide consisting of M1Ox contg. O2 to limit the electronegativity En1 and En2 to conform to En2-En1>=0. Either TeOx (0<x<2.0) is selected as the oxide to be used as the essential component and the additional material having 2.1 En2 is used or SnOx (0<x<2.0) is selected as the oxide and the addition material having >=1.7 En2 is preferably selected. By using the electronegativity in this way, M2 is more easily incorporated into a mixture of M1 and M1Ox as a simple substance. Accordingly, the characteristic of the reducing metallic oxide thin film can be easily controlled by the amt. of M2 to be added. Moreover, a reaction is difficult to occur when a film is formed, the reproducibility is improved and the production is facilitated.

Title: Automatic soldering device
Inventor: SEKI ASAO
IPC: B23K3/06
Filed: 1980-09-09
Abstract: PURPOSE: To perform soldering work automatically, surely and quickly by providing a driving mechanism to a supporting frame, and driving a feed cylinder or the like.  
     CONSTITUTION: A driving mechanism 17 (feed cylinder) is operated in the direction where a gear 14 revolves forward. However, the effect of braking is held applied to a feed wheel 15 by a frictional piece 16 and therefore the wheel 15 does not revolve, and an oscillating frame 8 oscillates around a feed shaft 6 until it abuts on a stopper. Therefore, the leading end of a lower solder guide cylinder approaches to a tip 2 from a transverse direction. When the frame 8 abuts on the stopper, the feed gear 14 revolves forward by overcoming the resistance of the piece 16 this time, then a feed shaft 5 revolves. Here, a feed roll 10 revolves to feed and advance wire solder 7. The rate of feeding matches the amt. of revolution of the shaft 6 and is determined by the stroke or the forward revolving amt. of the mechanism 17. Hence, soldering work is accomplished cooperatively with the tip 2.

Title: Data signal processor, decision feedback equalizer and filter adjustment method
Inventor: PRATER JAMES S
IPC: H04L25/03
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To minimize a data error in data transmission by adopting a decision feedback equalizer controlling a filter characteristic, based on an output signal from a code detection means. SOLUTION: A front equalizer 102 receives an analog signal to filter the signal based on a past data pattern. The filtered signal is sent to an addition circuit 106, and the addition circuit 106 adds the signal from the front equalizer 102 to the signal from a rear equalizer 104. The rear equalizer 104 corrects the signal by subtracting a rear edge of a pulse in a waveform. A slicer 108 generates the best estimated value of a data code when an input is inputted from the addition circuit 106. In the case of an adaptive equalizer, a coefficient in the front equalizer 102 is set, based on the data pattern from the slicer 108. Similarly, the coefficient in the rear equalizer 104 is selected, based on a polarity of a past pulse.

Filed: 1988-05-25
Abstract: PURPOSE:To make the size of a signal detection section receiving a signal small and light in weight by sending a light or magnetism transmission signal from a signal transmission section contactless to a signal detection section provided to a rotating body. CONSTITUTION:A signal detection section 2 comprising aggregate of assembly of optical semiconductor elements or magnetic semiconductor elements able to detect light or magnetism is formed over the entire circumference of an outer circumferential face 1a of a rotating body 1 provided freely rotatably.

Title: Variable attenuator
Inventor: SATOU MITSUE
IPC: H03H7/24
Filed: 1981-08-10
Abstract: PURPOSE:To change the attenuation stepwise, by connecting a resistive element between an input and an output terminal, constituting a unit attenuator through the connection of a pair of common terminals of a single pole double throw switch to the output terminal, and cascade-connecting a pluality of the unit attenuators. CONSTITUTION:In selecting a common terminal (c) of a single pole double throw switch to a fixed terminal (a), a signal flows in the route of an input terminal 1, the fixed terminal (a), the common terminal (c) and an output terminal 2. Thus, a resistive element 3 is short-circuited and no signal is attenuated at this unit attenuator 11. Inversely, in selecting the common terminal (c) to be connected to a fixed terminal (b), an inverse-L type resistance attenuator of 1 dB can be constituted. In other unit attenuators 12-14, through the operation of the single pole double throw switch, the control for the specified attenuation can be performed. Thus, through the operation of the unit attenuators 11-14, the attenuation can be switch in the step of 1 dB between 0 dB and 15 dB.
