Title: Pattern etching method
Inventor: SADARUSHIYAN RARU
IPC: C23F1/00
Filed: 1992-05-29
Abstract: PURPOSE: To provide a uniform pattern etching method for a copper sheet formed on a multilayer printed circuit board. CONSTITUTION: Uniformity is improved by adding the alkyltrimethyl ammonium chloride of alkyl chain whose number of carbons is 6-20 by an amount sufficient for giving intermediate power behavior to standard copper etching solution. It is especially in the case where an alkyl group is dodecyl, hexadecyl or octadecyl and it is added by 0.01-1.0 wt.%. Silicon antifoaming agent it added for preventing foaming during etching. When such method is used, etching speed is mass transportation controlled at low speed but it becomes almost independent of mass transportation for suppressing surface reaction speed at high speed. Thus, the non-uniformity of etching speed based on the fluctuation of the mass transportation condition of a processor is eliminated. Consequently, the yield improves and the processing of an acculate line multilayer circuit board is realized by the peculiar method.

Title: Electron lens current setting device
Inventor: INOUE HIROYASU
IPC: H01J37/248
Filed: 1990-06-20
Abstract: PURPOSE:To prevent generation of a large overshoot or undershoot in a very short time by increasing or decreasing the current supplied to an electron lens in steps with such a change amount as not damaging an amplifier, and thereby generating the setting to the target electron lens current. CONSTITUTION:From a control device 9, a comparator circuit 7 is previously fed with a reference current change amount delta for generation of an overshoot in a size which does not damage an amplifier 4. In the case D>delta, the comparator circuit 7 sends a signal delta to a convergence lens 5 through a D-A converter and the amplifier 4 and sends an add command to an adding circuit 8. In conformity to this add command, the adding circuit 8 adds the reference current change amount delta fed from a control device to the old added value (K+delta), and a signal (K+2delta) according to the addition, 2delta in this case, is sent to the convergence lens 5 through the amplifier 4 and also to a subtracting circuit 6. The subtracting circuit 6 sends a signal ¦D-2delta¦ to the comparator circuit 7, which compares the ¦D-2delta¦ with delta. Thereafter similar cycles are repeated in the comparator circuit 7 until the signal from the subtracting circuit 6 becomes smaller than the reference current change amount delta.

Title: Selecting method for zeolite, and adsorbent whose main component is natural zeolite
Inventor: NISHIZAWA JIYUNICHI
IPC: C01B39/26
Filed: 1978-12-29
Abstract: PURPOSE: To select a cheap adsorbent with high performance by a method wherein natural zeolite is graduated according to the content of iron impurities.  
     CONSTITUTION: Natural zeolite, whose content of iron (conversion to Fe 2 O 3 ) is little, among one, which Si/Al ratio is approximate not less than 4, is regarded as high quality. The higher the quality is, the more excellent the adsorption capacity is. For example, the natural zeolite, whose content of iron is approximate not more than 0.7wt% in conversion value to Fe 2 O 3 , indicates adsorption capacity equal to or higher than synthetic mordenite or a molecular sieve 5A to each gas. Even natural mordenite, whose content of iron is approximate not more than 10wt% in conversion value to Fe 2 O 3 , can be provided with adsorption capacity equal to or higher than the molecular sieve. Thus, cheap zeolite with proper grades can be selected in response to the kinds of gases to be adsorbed and adsorptive degrees.

A memory 12 stores the value of the signal lines 2a, 2b corresponding to the polarity at the normal state of the telephone line. That is, the polarity of the normal state of the telephone line is detected and registered on the memory 12, a main control section 1 supervises a polarity inversion detection section 2 based on the polarity of the normal state registered on the memory 12 to detect the polarity inversion. Thus, two wires of the telephone line and two wires of facsimile equipment can be connected in any way and then the connection is much facilitated.

Abstract: PURPOSE: To indicate a thickness of a document or another record media passing a feed path by generating pulses by a pulse generating means and counting the number of pulses generated by a counting means. CONSTITUTION: In the case of passing a document or another record media through a document transporting unit 14, the document is driven at a nip between rolls 16 and 26. If a thickness of the document is thinner than an air gap 50, a set 32 of the rolls are not brought into contact state, and no pulse is generated while the rolls 46 remain steady. If the document is thicker than the gap 50, the set 32 of the rolls are urged by the document, brought into contact with the rolls 46, and since the set 32 of the rolls are rotated, the rolls 46 are driven and rotated. As the rolls 46 are rotated, a flow of ON/OFF pulses are generated by a protrusion 54 and the gap 50 on a timing disk 52 passing a sensor 58 and give an indication of passing the document of the excess thickness to a data processor.

Title: Operation control device for solenoid safety valve
Inventor: YUKIMURA MASAHIKO
IPC: F23N5/20
Filed: 1984-08-03
Abstract: PURPOSE:To prevent the leakage of raw gas by quickly closing a safety valve when the burner unit fails to be ignited by providing a charging circuit with an auxiliary charging circuit consisting of an actuating solenoid and a parallel side line. CONSTITUTION:An auxiliary charging circuit 23 consisting of an actuating solenoid 10 and a parallel side line is disposed in a charging circuit 21. When an actuating member 4 is pushed, it moves back from the closed position A to the ignition position B, and when it returns to the open position C by releasing the push, a gas passage 5 is opened and at the same time an igniter 15 performs its function to ignite the burner unit 3. As the actuating member 4 returns from the ignition position B to the open position C, a switch 24 is caused to close to render the circuit 23 functioning. That is, in a case where the burner unit 3 fails to be ignited, the charging current of the charging circuit 21 is bypassed via the auxiliary charging circuit 23 to suspend the energization of the actuating solenoid 10. In this manner, the solenoid safety valve 9 is quickly closed as soon as the holding by the solenoid is removed, and an accidental release of raw gas is prevented.
