Abstract: PURPOSE:To attain the stable transmission/reception of a selecting signal by forming a high resistance loop at the sending of a PB signal, and when the high resistance loop is detected by an intra-station equipment, stopping the sending of a sound source and supplying the PB signal to a PB signal receiving circuit. CONSTITUTION:When a key 155 is depressed, a PB oscillator 254 oscillates a PB signal at the frequency corresponding to the key and the PB signal is amplified 153 and sent to the intra-station equipment 14 through contacts 152a, 152b. The sent PB signal is inputted to a PB signal receiving circuit 45 through a detecting circuit 141, held in a register of a selector 144 and one sound source is selected out of sound sources in terminals 461-46n by a selector 144 based on the held contents. When the key 155 is depressed, a relay 156 is driven by a common contact to close a contact 156a and a loop is formed between subscriber's lines 12a and 12b through a resistor 159. The voltage difference between the lines 12a, 12b is changed by the high resistance loop and the change is detected by the circuit 141, so that the sending of the sound source from the intra-station equipment is stopped and an AC signal on the lines 12a, 12b is sent to the circuit 145.

IPC: B03C3/01
Filed: 1987-01-14
Abstract: PURPOSE:To minimize discharged dust concentration without increase in GGH corrosion scale by estimating a SO3 concentration indirectly from gas temperatures at an air preheater outlet and a SO2 concentration at a desulfurization inlet, and controlling a lower limit value of dust concentration at an EP outlet in accordance with the estimated value of SO3 concentrations. CONSTITUTION:For instance, data of readings of a thermometer 10 provided at the outlet of an air preheater and an SO2 meter at the inlet of a desulfurization device 5 is entered into an EP dust concentration control device 9. Next, SO3 concentrations are estimated arithmetically in the control device 9 to obtain the lower limit value of dust concentrations which permits maintenance of a required D/S. Then the charge value of a power supply 7 for EP is controlled in such a way that just concentrations measured by means of an EP outlet densitometer 8 are constantly set to the lower limit value. Consequently, operation is possible with EP outlet dust concentrations maintained to the lowest level, while GGH corrosion is held down within a constant range.

IPC: H01L29/72
Filed: 1987-01-13
Abstract: PURPOSE:To prevent diffusion impurity from flying away out of a buried diffusion layer, putting the control of specific resistance of the next epitaxial layer out of order, and generating low resistance on an epitaxial layer boundary surface, by covering a buried diffusion region with a selective epitaxial layer. CONSTITUTION:An selective epitaxial layer 4 is selectively grown only on a buried diffusion layer 3 being a non-doped layer, while SiH2Cl2 is made a source under a reduced pressure, and HCl is made to flow. A substrate oxide film 2 used in the process of selective epitaxial growth is eliminated. As a non-buried region is covered with an oxide film, it does not come under the influence of auto-dope from the buried diffusion layer at the time of selective epitaxial growth. A desired epitaxial layer 5 is grown by applying ordinary SiH4, SiCl4, etc., to a source, and then a desired semiconductor device is obtained by an oridary diffusion process. On the occasion of this ordinary epitaxial growth, the buried diffusion region is covered with the selective epitaxial layer, and its surface concentration is made low by four figures, so that the ordinary epitaxial growth has no effects of auto-dope at all.

Title: Method for analyzing impurity on surface of semiconductor silicon substrate
Inventor: WATANABE KAORI
IPC: H01L21/66
Filed: 1992-01-20
Abstract: PURPOSE:To analyze elements having lower ionization tendencies than silicon, by using an analyzing method based on the relation of hydrofluoric acid vapor decomposition-atomic absorption spectro photometry which can not be applied to conventional analyses. CONSTITUTION:Au element contained in the silicon wafer contaminated by Au element of 1X10<13> atoms/cm<2> an in its density is analyzed and recovered. In this case, an analyzing method based on the relation of hydrofluoric acid vapor decomposition-atomic absorption spectro photometry is used, and agua regia is used as a recovering liquid. Fig. 1 shows the relation between the Au recovering rate and the treatment frequency in the foregoing case and the similar relation in the conventional case wherein pure water is used as the recovering liquid. As shown by this figure, the Au recovering rate is 98% when the recovering treatment by agua regia is performed two times, but Au can not be recovered at all in the conventional recovering treatment by pure water since Au can not be dissolved in pure water. The lower limit of determination in the recovering by agua regia is the low level of 10<8> atoms/cm<2> in Au density. The present method can be applied to Au, Pt, Ag, and Cu.

Abstract: PURPOSE:To prevent the inner surface of a pipe from becoming angular and to improve the quality and yield of a product by twisting the pipe in a titled method where plural sets of rolling mills consisting each of plural rolls are arranged in series. CONSTITUTION:Each stand of a drawing mill constituted of 28 sets of stands, for instance, has three rolls, and the calibers of adjoining two (n)th, (n+1)th stands are in the positional relation as shown by the figure, and the (n)th stand has a characteristic value (ovality) of b/a. Thereupon, all the stands are separated into two blocks of the 1st-14th and the 17th-28th stands to set a twisting device of material at the position of the 16th stand by removing the rolls of the 15th stand. That is, the rolls having the same shapes as those of the 14th stand are cut into the rolls having each a 15 deg. inclination, to use them as a twisting device. The material after being subjected to rolling reduction by the 14th stand is twisted while passing through the 16th stand, and is subjected to rolling reduction by the 17th stand while being twisted by 30 deg.. Thus the material is rolled by the succeeding stands in a state of being deviated by 30 deg. in phase from the state in the first half stands into a dodecagonal inner face thereby making the angular one uniform.

Abstract: PURPOSE:To enable the handling of emergency situations properly by connecting only an emergency load to a generator in case of such situations while the function of separating the load by an air suction temperature is halted. CONSTITUTION:In the normal operation, a load controller M separates loads sequentially in the order of importance as the air suction temperature of a gas turbine detected by a temperature detector TH rises beyond the output limit characteristic. When an emergency occurs, a signal is output from an emergency detector D to connect only the emergency load to a gas turbine generator while the load controller M is halted. This can maintain the supply of power to the emergency load at an emergency.

Abstract: The invention relates to an arrangement for testing integrated circuits for sensitivity to electrostatic discharges at the connecting pins with the aid of a high-voltage discharge with all possible combinations of in each case two different connecting pins of an integrated circuit and measuring the input characteristics of these connecting pins before and after the discharge process. In previous test arrangements, the chip terminals were mechanically contacted. The test sequence was therefore not suitable for automation. For this purpose, the invention provides that the connecting pins of the respective test chip (1) are connected to an adaptor (2) which, in turn, is connected to a relay matrix (3) for transmitting the high-voltage discharge of a relay matrix (4) for applying a logic level "1" and to a relay matrix (5) for applying a logic level "0" or earth level. The three relay matrices are selected by a processor (8) via a relay matrix decoder (6) and a relay matrix control (7). The processor is connected at the same time to a relay control (9) which operates other relay sets (10, 11 and 12) for switching the supply voltages, the high-voltage discharge and characteristics measuring device and the logic levels. <IMAGE>
