Abstract: PURPOSE: To increase the growing velocity which increasing the size of the device but using the source boat of multi-layer structure, and thus to obtain an even grown film.  
     CONSTITUTION: H 2  containing AsCl 3  is introduced from inlet (a) to be given a contact to 1sr-layer G11 and then 2nd- and 3rd-layer Ga12 and 13 to be then exhausted (d). Thus the source boat of the III-group metal features the multi-layer structure. As a result, the surface area of the source metal can be increased with the length of the source boat kept constant, and thus the reaction is advanced enough between the source metal and the material gas of the V-group halogenide. Thus, the growing velocity can be increased, also ensuring the vapor growth of an even crystal.

Title: Digital agc circuit
Inventor: HOSOKAWA TSUTOMU
IPC: H03G3/20
Filed: 1982-04-22
Abstract: PURPOSE:To attain quick response even to a signal having much noise, by detecting whether the input level exceeds the dynamic range or not in the operating processing section in the AGC circuit and providing an AND circuit, an exclusive OR circuit and a delay element. CONSTITUTION:The gain of a variable amplifier 1 is set to the state close to the maximum gain when a signal (i) is ''0''. Since a signal having a large level is inputted after the signal (i) goes to ''1'', a level exceeding the dynamic range is inputted to the input of an operation processing section 5, the output of a comparator 5-3 goes to ''1'' and a signal (j) goes from ''0'' to ''1''. The output (k) of the exclusive OR circuit 11 goes to ''1'', an FF9 is reset and the output (i) goes to ''0'' gain. As a result, an output (d) of a comparator 3 is inputted to an up-input of an up-down counter 7, the counter 7 is counted up in the period of a clock input signal (a), resulting that the gain of the variable amplifier 1 is decreased to the normal state quickly.

IPC: B01J20/24
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To recover metal elements in a high purity and high concentration with little mixing insoluble tannin in a liquid in which a metal element has eluded by minimizing the degradation of the insoluble tannin and prolonging the life as adsorbent. SOLUTION: This method is characterized in that the metal element is eluded by bringing insoluble tannin which has adsorbed metal elements into contact with an elusion liquid with pH 2 to 7 including fluorine ion with concentration of 0.001 mole/1 or higher. For the pH controlling agent, inorganic acid or hydrofluoric acid is used. By this, in the adsorbent insoluble tannin point of view, effects that the degradation of this tannin is little even with repetition of adsorption and elusion many times and that the life of the adsorbent is prolonged are expected. In the view point of the liquid in which metal element is eluded, the mixing of the insoluble tannin in this liquid is minimum and the metal element is recovered in a high purity.

IPC: G11B5/60
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a levitating head slider that can start the rotation of a recording disk normally even when a spindle motor is turned reversely. SOLUTION: When a magnetic disk is at a standstill, a slider body 22 is supported by support legs 33, 34, 35 with reference to a disk face.
