Abstract: PROBLEM TO BE SOLVED: To provide a sewing machine capable of preventing the needle and the bobbin thread cutting means from interfering with each other when a user manually rotates the upper shaft, etc., without regard to the timing when the power is off. SOLUTION: In this sewing machine, whether the power is off or not is judged (S3) from time to time while the ordinary sewing process is executed (S1). If the power is off, a presser foot lowering signal is outputted (S5). Accordingly, the presser foot is disposed at the cloth pressing position where a cloth to be sewn is pressed, and a bobbin thread cutting means is disposed in the same condition as in the sewing process. The electricity stored in the capacitor of a smoothing circuit of the power source is used for driving the above process. As a result, the bobbin thread cutting means can be retracted from just below the eye of the needle so that the interference with the needle can be prevented.

Title: Mos dynamic sense circuit
Inventor: OGURA ISAO
IPC: G11C11/4094
Filed: 1978-10-11
Abstract: PURPOSE:To improve sense sensitivity by compensating a decrease in high level potential by charging nodes at high level sides by feeding sense results back. CONSTITUTION:After sense circuit FF having a flip-flop formed of MOS transistors Q11 and Q12 is pre-charged, clocks (phi1) and (phi3) become zero in a read period to disconnecting nodes A1 and A2 of circuit FF and those N1 and N2 of boosting circuit RW from a power supply and each data is read out ot digit lines (d1) and (d2) to make clock (phiSA) zero, thereby performing sense operation. For example, when nodes A1 and A2 are ''1'' and ''0'' respectively, MOS transistors Q16 and Q26 of inverters I1 and I2 where sense results are fed back are ON and OFF and when clock (phi2) becomes zero after the sense operation, nodes N1 and N2 are ''0'' and ''1'' respectively while gates of charging MOS transistors Q15 and Q25 are ''1'' and ''0''. Then, when clock (phi3) becomes ''1'', high-levle-side node A1 only is charged by way of MOS transistors Q15 and Q14, causing a drop in potential. Therefore, the sensitivity of a sense circuit of large capacity can be improved.

Abstract: PURPOSE:To make automatic machining performable without entailing any positional slip and variations in a removal rate, by installing a machining device, provided with a copying attachment, on plural rails installed radially in opposition to a work, while letting a copying mechanical part copy directly on a curve machining part. CONSTITUTION:A machining device 9, after starting its operation, performs its reciprocating travel along a vane 3 at cw or ccw rotation of a rotary table 5 and also performs the machining operation of welding or finishing of a work line 4 with a machining electrode 11 automatically. A machining rate at this time is detected by a speed detector 14 via a speed detecting roller 13 being rolled on the top of the vane 3 and self-controlled by speed control. That is to say, the predesignated machining rate is set to a control unit in advance, comparing it with the detected result of the speed detector 14, and a quantity variation value is calculated, outputting it to a driving device of the rotary table 5, thus constant-speed control is performable to meet the designated machining rate all the time. Thus, highly accurate automatic machining is made possible to be done in any machining device without entailing any positional slip in all machining parts and variations in the machining rate or the like.

Title: Mobile communication system and channel assignment method in the same system
Inventor: FUTAKATA TOSHIYUKI
IPC: H04W28/12
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate radio wave interference between adjacent radio bases in a system and to improve effective frequency use of the system by assigning a channel in which the radio wave interference is not generated to communication of the radio base station based on information of the radio wave interference between radio base stations. SOLUTION: Radio base stations 1 to 5 form service areas 101 to 105. When there is a call from mobile radio equipment in the service area 101, the base station 1 which receives the call transmits an assignment demand signal of a communication channel to a controller. The controller which receives a demand signal assigns a speech channel and a time slot to be communicated with the mobile radio equipment. In the case, the controller does not give interference interruption to communication of nearby base stations 2, 4 and 5 which are already progressing at this point of time and, on the contrary, assigns a radio channel and the time slot which do not receive interference interruption from communication of the nearby base stations 2, 4 and 5 to communication of the mobile radio equipment itself.

Title: Stabilized power unit
Inventor: YOSHIKAWA SHIGEO
IPC: H03L7/085
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent an interference noise which is generated from a switching element by providing a switching power circuit and a phase-locked loop device which synchronizes phase of a triangular wave generator that constitutes power of the circuit with prescribed frequency. SOLUTION: Switching power compares error voltage for reference voltage of output voltage 21 with a reference triangular wave (being fHH2 here) which is produced by a triangular wave generator 18 in a comparator 16 and controls the error voltage with a DWM. When the output voltage 21 decreases, the switching voltage operates to increase duty of output pulse of the comparator 16 and an on period of a switching transistor 13. Also, it performs the opposite operation and outputs stabilized voltage when the output voltage 21 increases. At this time, basic triangular wave frequency synchronizes with fH/2 by means of a phase-locked loop device 19 and is interleaved in frequency because it is integer double of the fH/2 . Thereby, interference of switching frequency can not be seen on a screen to human beings' vision.
