Title: Successive forage feeder of hopper
Inventor: HIRANO NORIMASA
IPC: B65G65/46
Filed: 1980-12-09
Abstract: PURPOSE: To prevent forage from clogging in such a way that a feeding back conveyor is installed on a hopper which distributes forage to a breeding cage in a hennery, and when outflow of forage from the hopper is prevented, forage will return into the hopper of itself.  
     CONSTITUTION: Though forage in a hopper 1 is fed ahead by means of a lower conveyor 6, is flowed out through a falling port 4, and carried to a forage gutter by means of a pipe 16, in case where the falling port 4 is clogged, since forage at the front end part is pushed up by a blade 8, is fed in the rearward direction by means of a conveyor, and fed into the hopper, there is no event of stuffing forage at the front end of the lower conveyor, and no hindrance, such as conveyor turning stop, etc. can happen. Since there is difference in the number of teeth between a gear wheel 9 and a pinion 10, the upper conveyor has quick turning, the lower conveyor has slow turning, and they reversibly turn to each other.

Filed: 1986-07-23
Abstract: PURPOSE:To provide a MOSFET effectively prevented from soft errors due to alpha particles or the like and having a sufficiently stable substrate potential to be used as a switching transistor, by forming a cell capacitance in a first semiconductor region. CONSTITUTION:An N-channel MOSFET is composed of an N-type region 104 of a semiconductor film, a silicon film in a P-type region 105 and an N-type region 106, a gate insulator film 108 and a conductor film 109. A cell capacitance is formed in the N-type region 104 of the semiconductor film located in a groove 114, by the silicon film in the N-type region 104, an insulator film 102 and the silicon in a highly doped P-type region 111. The N-type region 104 and the section of the P-type region 105 in contact with the N-type region 104 are located in the thin silicon film surrounded by the insulator film 102. In this section, therefore, an extremely small number of minority carriers are produced by entrance of radiative particles such as alpha particles or the like. Accordingly, there is substantially no possibility that the funneling effect is created and many minority carriers are accellerated and collected to storage nodes. As a resulst, soft errors or other problems caused by the alpha particles or the like can be prevented effectively and the MOSFET having a stable substrate potential can be used as a switching transistor.

Title: Hit analyzer for digital circuit
Inventor: TSUJIMOTO ICHIRO
IPC: H04L25/02
Filed: 1985-08-08
Abstract: PURPOSE:To facilitate the analysis of a digital circuit by totalizing the output of a hit classifying circuit which classifies the continuance of a hit detected by a hit detecting circuit into hit ranges by the hit ranges, and calculating the probability of the hit regarding its generation frequency and continuance. CONSTITUTION:The hit classifying circuit 2 inputs a hit waveform and a clock from a hit detecting circuit 1 and classifies the hit waveform by a hit time according to inequalities. Output terminals 2-1, 2-2...2-N of the hit classifying circuit 2 correspond to hit ranges 1, 2...N. Therefore, the hit classifying circuit 2 outputs a pulse to a terminal for a hit range to which the hit waveform inputted from the hit detecting circuit 1 belongs. An analyzer 3 totalizes pulses inputted from the hit classifying circuit 2 by the hit ranges and calculates the probability of a hit regarding the number of times of the hit within a certain determined time, i.e. generation frequency and continuation, thereby outputting the result.

Title: Substitution tin plating method for copper material
Inventor: ITO JUNICHI
IPC: H05K3/24
Filed: 1992-06-09
Abstract: PURPOSE:To always form a uniform Sn-plating film without defects for substitution Sn plating on Cu parts by controlling the concn. ratio of Sn ion to Cu ion in the plating liquid to a specified value. CONSTITUTION:In the process of substitution Sn plating on Cu parts, Cu parts are dipped in a substitution Sn plating liquid containing dissolved tin (II) chloride, sodium cyanate, and sodium hydroxide. While plating proceeds, the concn. of Sn ion in the plating liquid decreases and the concn. of Cu ion increases by dissolution of Cu from the Cu parts, and this causes defects in plating. Therefore, concns. of Cu ion and Sn ion are always measured and controlled to keep the ratio of Cu ion conc./Sn ion concn. to <=0.7. By this method, production of defective plating film is prevented and the obtd. Sn plating film is always uniform. Moreover, excess discharge or excess supply of Sn ion can be prevented.
