Title: Power converter
Inventor: SUZUKI HIROKAZU
IPC: H02M7/497
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To obtain a power converter suitable for DC power transmission in which DC current is prevented from increasing by an arrangement wherein the current on the DC winding side of a converter transformer is detected and controlled to match commands delivered from a DC voltage controller and a reactive power controller. SOLUTION: DC winding side currents of converter transformers 4A, 4B are detected, respectively, through current transformers 3A, 3B and controlled, respectively, through AC current controllers 11A, 11B to match respective command values delivered from DC voltage controllers 9A, 9B and a reactive power controller 10. More specifically, when the DC voltage of a converter 5A is higher than a DC voltage reference 51A, a DC voltage controller 9A delivers a current command for lowering the DC voltage and the AC current controller 11A controls the output voltage command for the converter 5A in accordance with that command thus matching the DC voltage of the converter 5A with the reference level. Similarly, the voltage of converter 5B is matched with a DC voltage reference 51B and voltage unbalance between two converters 5A, 5B is eliminated thus reducing power loss.

Title: Line switching system of radio system
Inventor: KIZAWA TOSHIYASU
IPC: H04B7/24
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To evade the use of a charged ground line by making a slave station request resending from a master station by using the ground line, only when it is judged that reception can not be performed on the slave station side and sending no request to resend, unless an answer signal can be received on the master station side. SOLUTION: The constitution of the radio system at normal time is similar to the conventional system. A sequence of communication using a satellite at normal time is also similar. Namely, time information is added to the data to be sent from a master station (HUB station) 1 and even when there is no data to be sent from the HUB station 1, only the time information is sent. Only when it is judged that reception can be done on a slave station (VSAT station) 3-n, the VSAT station 3-n requests resending from the HUB station 1 by using the ground line. When the HUB station 1 fails to receive the answer signal from the VSAT station 3-n, the HUB station 1 does not request resending from the VSAT station 3-n. Therefore, if the answering signal cannot be received by the master station from the slave station, resending need not be requested by using the charged ground line.

Title: Light pen position detecting system
Inventor: MAEKAWA NORIAKI
IPC: G06F3/033
Filed: 1984-12-26
Abstract: PURPOSE:To prevent a position detection error in row and column directions by detecting a position taking a maximum amount of light among detected amounts of light of a character display position as a contact position of a light pen. CONSTITUTION:When address signals (y, x) represent respectively row and column direction address signals Y, X, Y+1, X+1, Y-1, X-1 respectively, the count of amount of light counters 32-34, 44-46 represent the amount of light inputted to the light pen 3. As the count is closer to the center of the visual field of the light pen, the value is increased. A CPU16 reads the count of the amount of light counters 32-34, 44-46 just after the next display frame when the first light pen output pulse is generated and selects the maximum value in both row and column directions. The display position in the row and column directions represented in the signals (y, x) corresponding to the maximum value is decided as the center position of the light pen 3. Even when the contact position of the light pen 3 is shifted slightly in the row and column directions, the position is detected accurately.

Title: Evaluating device for noise rating
Inventor: HATA TSUTOMU
IPC: G01R31/00
Filed: 1988-10-31
Abstract: PURPOSE:To quantitatively evaluate the noise rating of an integrated circuit device by providing a tester connected to plural external terminals of the integrated circuit device, and an impedance element between a earth terminal of the integrated circuit device and an earth. CONSTITUTION:By an input device 2, outputs of data input/output terminals D1-D4 are set to a high level or a low level. When VCC is impressed, an output current of an IC 1 and a charge/discharge current of the inside flow into an earth through a resistance R from an earth terminal of the IC 1. In this case, an earth level of the IC 1 floats up by a voltage applied to the resistance R, and becomes a noise source. In this case, whether outputs of the terminals D1-D4 are different from an output which is set by the device 2 or not, that is, whether a noise generates a malfunction in the IC 1 or not is measured by a tester 3. Unless the malfunction is generated, the resistance R is varied, and in the same way, the measurement is executed. This operation is repeated until a malfunction is generated. A value of the resistance R at the time when the malfunction is generated first becomes a noise rating of the IC 1.
