Title: Detecting system of interference
Inventor: MONMA KOUJI
IPC: H04B17/345
Filed: 1982-02-25
Abstract: PURPOSE:To improve the ability of interference detection caused by the same frequencies, by stopping a desired wave while no voice signal exists, and detecting the level and a clock signal of the interference wave. CONSTITUTION:A signal is transmitted from a transmitter while the voice signal exists. On the other hand, a signal separator 15 of a receiver obtains an end code and a radio equipment discriminating signal and transmits them to an interference discriminator 18. The discriminator 18 starts the monitor of the presence/absence of the clock signal from a clock signal pickup device 14 and the state of level from a level detector 13 with the code and signal. If interference of the same frequency takes place, even if there is not desired wave due to the interruption of voice, the level is detected at the level detector 13, the interference wave of the same frequency is demodulated, and since the clock signal only is detected from the clock signal pickup device 14, the discriminator 18 discriminates that there is an interference.

Title: Method for reproducing information
Inventor: SATO TOSHIHIKO
IPC: G11B20/00
Filed: 1987-02-09
Abstract: PURPOSE:To shorten useless time and to rapidly reproduce a bit of information by controlling a system so that a relative moving speed at the time of detecting information is higher than that of no information detection. CONSTITUTION:When an optical card 1 is inserted into a reproducing device 20 and its insertion is detected by a photointerrupter (PRIN), the card 1 is carried up to a specified position shown by a short dashes line. As the result, an optical head 11 is accessed to a specified band in which required data are recorded, the optical card 1 is moved in a right direction and information recorded in the specified band is read out. When all the information is read out and detected by a photointerrupter (PRB), the reading of the optical head 11 is stopped, the moving direction of the head 1 is inverted and then the head 1 is returned up to a position to be detected by a photointerrupter PRF at moving speed faster than that of reading operation.

Title: Phased array radar equipment
Inventor: TOMIZUKA MASANORI
IPC: G01S7/02
Filed: 1983-02-23
Abstract: PURPOSE:To improve angle precision more than angle precision determined with a beam width by controlling a scanning angle signal generating circuit and a receiving A/D converter through a scanning angle setter and allowing scanning beams to overlap to generate a corresponding receiving signal. CONSTITUTION:By the control of a scanning angle setter 14, a scanning angle signal generating circuit 9 allows scanning beams to have a width thetaB and sets the scanning beam angle to a thetaB/n. Meanwhile, an A/D converter 12 of a receiving circuit is controlled also by the setter 14, and only a receiving signal corresponding to the beam angle thetaB/n is subjected to A/D conversion and is outputted. Thus, even if the beam width is wide, the angle precision is improved more than the precision determined with the beam width.

Title: Sealing device
Inventor: IKEDA YASUHIRO
IPC: F16J15/3232
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To improve eccentric followability of sealing in a sealing device adapted to a shaft seal part by forming a circumferencial groove on the resin-made sealing member which has a lip extended from a sandwiched portion through a bent portion, so as to extend from the sliding surface of the lip to the sandwiched portion over the bent portion. SOLUTION: This sealing device 1 for sealing a gap between a shaft 70 and a housing 80 is composed of a metal circle 20, sealing members 30 and 40. The sealing member 40 has a portion 41 sandwiched between an inward flange 22 of the metal circle 20 and a diametral portion 32 of the seal member 30, and a lip 42 axially bent from the sandwiched portion 41 through a bent portion 44. The sealing member 40 is made of resin. A pump groove 43 is formed on a sliding surface of the lip 42 against the shaft 70. The pump groove 43 is so formed that fluid is flowed to the side of sealing fluid O by relative rotation of the shaft sealing device 1 in respect to the shaft 70, to obtain pumping effect. Eccentric follwability of the sealing 40 is thus improved.

Title: Digital filter
Inventor: MARUYAMA YUICHI
IPC: H03H17/02
Filed: 1991-01-30
Abstract: PURPOSE:To reduce the area of a chip and the cost of this digital filter by allowing the preceding conversion means to form an operation signal to a filter coefficient of the succeeding conversion signal and apply the formed signal to the succeeding conversion means. CONSTITUTION:A shift register 1, a latch circuit 2 and a decoder 3 constitute a 1st decimation filter and a coefficient memory 4, a shift circuit 5, a complement circuit 6, a reset circuit 7, an adder 8, and an accumulator 9 constitute the 2nd decimation filter. The memory 4 successively outputs the coefficients of an FIR filter and the adder 8 integrates 32 outputs of the accumulator 9 and outputs the integrated result. Since an operation signal for the coefficient of the 2nd decimation filter is outputted instead of an arithemtic result of the 1st decimation filter as the output of the 1st decimation filter, circuit size can be reduced.

Title: Charging stopping state deciding and processing system
Inventor: ISHIKURA TOMOHIKO
IPC: H02J3/00
Filed: 1994-02-28
Abstract: PURPOSE:To decide a charge stop state quickly by tracking a reference node and an adjacent node sequentially except open branches and already decided branches thereby deciding a charged state. CONSTITUTION:Current states of all branches are set and all power supply nodes are set to charge thus preparing a decision node list. One reference node is then taken out from the list while a branch address is taken out from a connection branch address list of reference node. If the node is closed, a decision history is inspected and if a decision is not made yet the decision history is set with a decision over. An adjacent nonreference node is then taken out from a pair of connection node address of that branch and if that node is not charged, that node is set with charging and the address of adjacent node is additionally listed. The decision is ended when NULL pointers are present at the next addresses of the connection branch address list of reference node and the decision node list thus making a decision effectively.
