Title: Power-supply apparatus
Inventor: OTAGAKI KAZUHISA
IPC: H02M7/12
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To obtain a power-supply apparatus in which a power factor can be enhanced efficiently and in which higher harmonics can be suppressed. SOLUTION: When a switching transistor which is installed across output terminals of a rectifying circuit is switched, a high-frequency switching signal ST1 (time α) is output from the zero-crossing point P of an input voltage, and a high-frequency switching signal ST2 (time β) is output in succession. In addition, when the input voltage is brought close to a next zero-crossing point P, a high-frequency switching signal ST3 (time γ) is output. Here, the duty ratios of the switching signals ST1, ST3 is set according to the current value of an input current, and the duty ratio of the switching signal ST2 is set according to an output voltage. Thereby, while the output voltage is being controlled, a power factor is improved, and higher harmonics are suppressed.

Title: Multi-wavelength band luminous element
Inventor: SERIZAWA AKIYUKI
IPC: H01L33/08
Filed: 1978-03-06
Abstract: PURPOSE: To reduce the loss of the optical signal output by generating the optical signal of one wavelength band with application of the electric signal to the 1st luminous element from outside and also generating the optical signal of the different wavelength band from the 2nd luminous element via the other electric signal to then transmitting these two electric signals into the same direction.  
     CONSTITUTION: N-type layer 8, P-type layer 9 and N-type layer 10 are formed on N-type semiconductor substrate 7 in order to form the two wavelength band luminous elements featuring the hetero-junction. In this case, the band gap of layer 9 is set larger than layer 8, and also the larger gap is secured for layer 10 than layer 9. Then the electrode is attached to layer 7, 9 and 10 each, and forward electric signal 11 is applied to layer 10 and 9 with backward electric signal 12 applied to layer 9 and 7 respectively. As a result, the optical signals featuring the wavelength band centering wavelength λ 2  are generated from the boundary between layer 10 and 9; and the optical signals featuring wavelength λ 1  are produced from the boundary surface between layer 8 and 9 each. These two kinds of optical signals are then transmitted via the same transmission line at one time, thus reducing the loss of the optical signal output extremely.

Abstract: PURPOSE:To reduce the abrasion of a slider as small as possible, by mounting one or more of a conductor part which is formed by laminating an insulator and a conductor and exposed to at least one annular or circular arc surface and a conductor terminal formed to the part different from said surface. CONSTITUTION:The take-out electrode 14 formed to an inner peripheral surface 13, an effective positional information electrode 15 in a state electrically connected to said take-out electrode 14 and a dummy electrode 16 in a state insulated from said take-out electrode 14 are provided to an annular outer peripheral surface 12 and, further, the gap G of the insulating part 17 adjacent to the electrodes 15, 16 is made smaller than the radius R of the contact surface of a slider 18. Because the gaps G between the electrodes 15, 16 on the slide surface of the positional information electrode of the outer peripheral part is smaller than the radius R of the contact surface of the slider 18, the slider 18 is contacted only with an electrode material and, even if the electrode material is formed by a ceramic laminating technique, said slider 18 is not collided with the ceramic surface extremely harder than the material quality of the slider and, further, does not slide with the ceramic surface. As a result, the abrasion of the slider is markedly reduced.

Title: Method of cutting sliver during replacing of can
Inventor: INAGAKI KAZUHIRO
IPC: D01H9/16
Filed: 1987-02-06
Abstract: PURPOSE:To aim at miniaturizing a can replacing device by stretching a sliver connected to a full can and a coiler tube between the full can and an empty can outside of a dividing line. CONSTITUTION:When an empty can 4 located at a storage position A becomes full, a full signal is delivered so that a coiler tube 2 rotating at a low speed is located at a position 3A outside of a dividing line L, and an empty can 4 is pushed out to the storage position A from a stand-by position B by means of a pusher 6. With this arrangement, the full can 7 is pushed out to a replacing position under a ball-push condition so that the replacement of cans can be made. Then, a press means 9 allows a cylinder 15 to extend into a free space 11 inside of a can conveying path 17, and therefore a stretched sliver 8 is clamped on the rear surface of a coiler plate 12 and is cut by vertically moving a cutting blade along an operating path 20. The end piece of the sliver 8 is suspended down into the empty can 4 and stored therein while a spinning operation is continued. Thus, a space required for the cutting of the sliver may be limited to the free space required for replacement of the cans, thereby it is possible to miniaturize the can replacing device.

Abstract: PURPOSE:To discriminate errors in a transmission line, by making mark rate modulation of a signal in mBnB conversion at a discriminating signal frequency f1 for a binary signal in service at a terminal relay device, and detecting the change in the frequency f1 at a monitor circuit in the relay device. CONSTITUTION:A data input is inputted to an mBnB code converter 15 with a transmission line clock frequency and transmits an output of modes 1 and 2 to a mark rate modulator 16. The modulator 16 takes data synchronism of the modes 1 and 2 in the frequency f1 from a frequency divider 17 for modulation. The output of the modulator 16 is transmitted to a transmission line via a precode circuit 18. In a monitor circuit in a relay device, the frequency f1 component is picked up from a signal inputted from the transmission line and the disturbance of patterns in the f1 is detected, allowing to discriminate errors in the transmission line.
