Title: Current controller for power converter
Inventor: SUGAWARA SHOGO
IPC: H02M7/48
Filed: 1990-03-23
Abstract: PURPOSE:To make constant the voltage difference in the vicinity of zero capacitor voltage by arranging an integrator at a hysteresis comparator section and providing another hysteresis comparator for judging the output level of the integrator. CONSTITUTION:Output of an inverter(I)2 goes zero at time point T2 and an integrator 56 starts integrating operation, and after reaching a peak at time point T6 the output deceases. Current difference reaches the lower limit of the hysteresis width of a hysteresis comparator(HC) 54 at time point T7 and the 12 produces a positive output. Consequently, output of the integrator 56 goes zero. The integrator 56 resumes integrating operation at time point T3 and when the output reaches the upper limit of the hysteresis width of HC 57, output of the HC 57 goes L. Consequently, output of the integrator 56 goes zero. When the I2 produces a negative output, the current difference decreases and reaches the lower limit of the hysteresis width of the HC 54 at time point T9, and thereby the output of the I2 goes zero. Consequently, the integrator 56 resumes integrating operation and produces a negative output, and the output of the HC 57 goes H at time point T10 and thereby the I2 produces a positive output.

Title: Structure and method for butt joint reinforcements
Inventor: YAMAZAKI FUJIO
IPC: E04G21/12
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost structure for butt joint reinforcements thereby to ensure easy construction and strong pressure contact. SOLUTION: The end of a reinforcement 1 is inserted into a through-hole in a non-circular sleeve member 103 with an elliptical or polygonal outline and a compressive force W is exerted to a portion to be joined to plastically deform the sleeve member for pressure contact. As a compressive force is applied on the portion to be deformed which is farther from the axial center of the sleeve member and more reduced in cross section, a great deformation amount is obtained with a small compressive force. In this way, a smaller compressor is required, workability at a construction site is improved and a great joint force is obtained at a pressure contact portion subjected to unequal pressure contact.

Title: Voice communication method and voice communication device
Inventor: SASAKI SEIJI
IPC: G10L19/08
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To reduce the quality degradation of reproduced voice by applying the same interpolation process as the process on the reception side to a frame transmitting the synchronization signal on the transmission side so that the quality degradation of the reproduced voice of a frame discarded with voice coding information does not affect the succeeding frame. SOLUTION: A transmission section feeds a voice input in a frame ft0, extracts no voice information and interpolates voice information in frame ft1, and transmits the frame synchronization signal in frame ft2 to secure the synchronization of frame with the reception side. The interpolation of voice information in frame ft1 and frame ft51 is made the same as the interpolation by a voice decoder on the reception side. If the interpolation substituted with the voice coding information of the previous frame is applied on the transmission side, for example, the interpolation substituted with the voice coding information of the previous frame is likewise applied on the reception side. Any interpolation method can be used as far as the same interpolation is applied on the transmission side and reception side.
