Title: Method and device for recovery of telephone terminal device
Inventor: KARASAWA TSUTOMU
IPC: H04M3/54
Filed: 1983-03-07
Abstract: PURPOSE:To transfer a call with no disturbance even if a connection is made in reversing in polarity of an originating telephone by inverting in polarity of the originating telephone circuit to produce a connection signal after the handset of a telephone of the remote side is picked up for answer. CONSTITUTION:When a see-hold relay 17 is closed with inverted polarity of a circuit, a photocoupler 32 is turned on and a DFF34 is reset. Then a negative output emerges at a positive inverse output 38, and a positive output emerges at an output 37. This state is stored in a main control part 27. When the handset of a telephone of the remote side is picked up, the polarity of a terminal 18 is inverted. Thus the coupler 32 is turned off to release a reset state of the DFF34. When a trigger pulse is applied to T of the DFF34, the positive and negative outputs emerge at output terminals 38 and 37 respectively. These outputs are compared with the output stored in the part 27 to decide the answer of the telephone of the remote side.

Title: Measurement of density of chromate ion and dichromate ion
Inventor: SERIZAWA KOICHIRO
IPC: G01N27/416
Filed: 1989-02-16
Abstract: PURPOSE:To facilitate the removal of a deposit on the surface of an electrode while achieving a reduction in the loss of an electrode and an extension of the life thereof utilizing the nature of relatively high resistance to corrosion in an acid solution by using highly pure aluminum as electrode material. CONSTITUTION:Highly pure aluminum has a chemical nature that when it is left alone in the air, it loses luster with the generation of a thin film of oxide but not be corroded inside thereof. It is dissolved into acid to form a corresponding salt but is not corroded relatively by concentrated nitric acid. A resistance increases with a decrease in purity. Aluminum is higher in ionization tendency than zinc and is more susceptible to oxidization. In comparison of equilibrium between zinc and aluminum, Al<3+>+3e  Al-1.66 (Volt), Zn<2+>+2 e  Zn-0.76 (Volt) holds. Accordingly, highly pure aluminum is preferable as electrode material.

Abstract: PURPOSE:To reduce a leakage magnetic flux by generating magnetic fluxes around the primary winding and secondary winding as positive-phase magnetic fluxes by supplying single-phase power from two terminals of a triangular winding, by short-circuiting two terminals of a star winding, and by short-circuiting the other one terminal and a neutral terminal. CONSTITUTION:As an exciting current is supplied to primary winding 2 from single-phase power source 4, the current of capacitor 6 for phase advance is superposed and supplied to primary cable 3a and current I1 flows through the coil between terminals V and W of primary winding 2 to flow current I2 through the coil extending terminals V, U and W in sequence. The current flowing through feeding cable 3b is measured by current transformer 5 and adjustments are so made that the sum of currents I1 and I2 will be equal to the rated current of winding 2. With regard to winding 3, I3 flows through the closed circuit of neutral point (o), and terminals (v) and (w), and short-circuit current I4 also flows through the closed circuit of neutral point (o), neutral terminal o-1 and terminal (u) as shown in the figure. Thus, the directions of currents flowing through respective windings are set in the direction where a positive-phase magnetic flux is generated, thereby reducing a leakage magnetic flux.

Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a mass balance of the whole device by preventing dislocation of an inside rotary member from the shaft center by centering the inside rotary member to a rotary shaft on both end sides. SOLUTION: The tip side of an inner shaft 10b as an inside rotary member is supported by an inner race 16a of a ball bearing 16 for supporting an outer case 10a as an outside rotary member on a propeller shaft 16 being a rotary shaft of the inner shaft 10b. The rear end side of the inner shaft 10b is supported by a support part 26c on the propeller shaft 26. Thus, since core dislocation is not caused on one end part side since the inner shaft 10b is centered to the propeller shaft 26 on both end sides, there is no possibility of being dislocated from the shaft center to thereby prevent the deterioration of a mass balance of the whole device caused by dislocation from the shaft center of the inner shaft 10b.

Filed: 1992-02-25
Abstract: PURPOSE:To simplify the processing of a signal line from a sensor and to specify a depression position with the necessary minimum number of sensors by arranging the sensors in a straight line at one side end part of an operation surface and at a prescribed distance. CONSTITUTION:Vibration is detected by the sensors S1, S2 and S3 arranged at one side end part of table glass 1 at the different timing by depressing an arbitrary point on the table glass 1 surface with an input pen 12. The depression position of vibration from the detected depression position is operated by a timing difference when respective sensors S1-S3 receive. Thus, the content of an item allocated in accordance with the depression point position can be inputted. Since the sensors S1-S3 are arranged at one side end part of the operation surface in a line, the signal line including the detection signal can be processed on the same side. Furthermore, the depression position can be specified by at least three sensors by setting the arrangement positions of the sensors to be objective positions by providing the sensors S1 and S3 at prescribed intervals with the sensor S2 as a center.

Title: Apparatus and method for automatic inspection of soldering state of circuit board
Inventor: JIYON ADAMUSU
IPC: G01N23/18
Filed: 1987-02-20
Abstract: A method and apparatus for measuring structural characteristics of a manufactured circuit board containing solder joints by automated real-time digital X-ray radiographic inspection techniques. A circuit board under examination is automatically positioned by a digitally controlled multi-axis positioning system between an electronic X-ray source and an electronic X-ray imaging system. X-rays, in a beam of X-rays from the X-ray source, are directed towards the circuit board. The X-rays are absorbed, scattered and transmitted through the circuit board. The X-rays transmitted through the circuit board are directed upon the X-ray imaging system. The X-ray imaging system converts the transmitted X-rays into digital images which represent the radiographic density of the portion of the circuit board under examination. The digital images are stored within a digital image processor. A computer, under program control, performs calculational measurements on the digital images so as to measure the structural characteristics of the solder joints and components on the circuit board. The calculational measurements are compared to predetermined standards corresponding to acceptable quality standards programmed into the computer. In response to the comparison, the computer provides an accept/reject decision on the circuit board in addition to providing manufacturing process control information for correction of found defects.

Abstract: PURPOSE:To markedly reduce the probability of reading failure by eliminating the effect on waste, scratches, dirts during the manufacturing process, by a method wherein the part to be provided with a discriminating mark is more recessed than the part to be provided with a semiconductor device. CONSTITUTION:In regard to a semiconductor substrate having the part to be provided with a discriminating mark to the semiconductor substrate to be provided with a semiconductor device, a semiconductor substrate 5 more recessed in the part to be provided with the mark than in the part to be provided with the semiconductor device is used.

Abstract: PROBLEM TO BE SOLVED: To simultaneously provide contrary characteristics of wear resistance and crack resistance by constituting a cover rubber layer from at least two layers, and forming these layers by use of mutually different rubber compositions. SOLUTION: A cover rubber layer 13 is formed of an outer layer 11 and an inner layer 12, and the number of the layers constituting the cover rubber layer may be three or more without being limited to two. These layers are formed by use of mutually different rubber compositions.

The ethylene-propylene-based rubber may be used alone or in combination of two or more kinds. Other rubbers may be mixed for the rubber composition in the range which will not cause deterioration in the characteristics of the ethylene-propylene-based rubber. Additives such as carbon black, vulcanizing agent, softening agent or the like are mixed to the rubber composition.
