Title: Shutter device for sheet material conveyance path
Inventor: KOJIMA SUSUMU
IPC: G06K17/00
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent mischief by the forcible opening of the closed sheet sheet material conveyance path when sending an abnormality signal out when detecting a lever for shutter position detection not being at its fixed position when a driving device stops. SOLUTION: On a card conveyance path 2, the shutter device 23 which opens and closes the card conveyance path 2 is arranged. When a stepping motor 5 as the driving device stops, a sensor 29 for shutter position detection judges whether or not the tip parts 27a and 28a of levers 27 and 28 for shutter position detection are at a position X to send an OFF signal to a controller when the above-mentioned tip parts 27a and 28a are not at the position X and an ON signal when the tip parts 27a and 28a reach the position X. The controller when judging that the sensor 29 for shutter position detection is not ON sends a driving signal out to an abnormal state informing means. The abnormal state informing means sends out the abnormality signal for interrupting the process of a card reader writer 21.

Title: Sewing machine
Inventor: SHIMIZU MASAKI
IPC: D05B19/12
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To correct the rotational phase of a shuttle driving motor so as to time the encounter of a needle point with the encounter of a sewing needle, prevent breakage of a needle thread or skippping stitches, improve sewing efficiency and form beautiful stitches at any sewing speed. SOLUTION: In high-speed sewing, the inertia of a needle bar vertically driven at a high speed by a sewing machine spindle with a sewing machine motor through a needle driving mechanism or a needle jumping mechanism increases, causing a delay in the vertical movement phase of the needle bar in the timing of encounter of a needle thread loop of a needle point.  However, in shuttle shaft synchronization control, on the basis of a phase difference command pulse P obtained in accordance with the rotation speed of the sewing machine spindle and a current phase difference pulse Q (S33: Q<P), as the rotation phase of the shuttle driving motor in relation to the sewing machine spindle is delayed and a phase delay in the rotation phase of the shuttle driving motor is increased in accordance with an increase in the rotation speed of the sewing machine motor (S34 to S36), irrespective of a sewing speed, a phase delay of the sewing needle in relation to shuttle for capturing a bobbin can be eliminated reliably.

Title: Fixed bed type three-dimensional electrode electrolyzer
Inventor: TAKAHASHI TAKESHI
IPC: C02F1/48
Filed: 1992-03-18
Abstract: PURPOSE:To minimize a decrease in treatment efficiency due to clogging in a fixed bed type three-dimensional electrode electrolyzer by making, in a three- dimensional porous electrode, through-holes by which the upstream side and downstream side of the electrode are connected. CONSTITUTION:In a fixed bed type three-dimensional electrode electrolyzer body 3 where a fixed bed type three-dimensional cathode 4, a three-dimensional porous electrode, for bringing microorganism contg. water to be treated into contact with it to give the water electrochemical treatment is installed, through- holes by which the upstream side and downstream side of the cathode 4 are connected are formed. Consequently the flow velocity of the water to be treated flowing inside the through-holes 5 becomes larger than that of it flowing inside porous narrow pores and the flow resistance of the water to be treated is decreased as a whole. Therefore the flow of the water to be treated inside the fixed bed three-dimensional cathode 9 is made smooth and the accumulation of extinct microorganism is decreased and the clogging becomes less apt to occur. Thus there is no necessity for replacing the cathode 4 and accordingly disassembling and assembling the electrolyzer body 3.

CONSTITUTION:A CMOS static memory cell has the first three Al wirings, i.e., two drain metals DM and one ground line GND, and wirings split into two bit lines D, D of the second Al wiring formed on the first Al wiring via interlayer insulation film. Therefore, the Al wiring necessary per cell gets three pitches, thus contriving to reduce the cell dimension by 3/5-3/4 as compared with conventional one. In the lower cell, the first Al wiring 134 for reducing the word line resistance runs in parallel with the polycrystalline Si film word line 121, which wiring is connected through an aperture 161 for every cell. Thereby, the speed up of action can be contrived in the lower cell by the reduction of the word line resistance with the increase of cell dimension by about 6% more than in the upper cell.

IPC: H02P29/40
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent it from becoming longer than reference chopping timing, and prevent the noise in an electric motor. SOLUTION: This controller generates an ascending order saw-tooth wave signal S5 and a binary signal S6 to generate the reference chopping timing, synchronized with this ascending order saw-tooth wave signal, by an ascending order saw-wave generating circuit 11, inverts the ascending order saw-tooth wave signal S5, adds a descending saw-tooth wave signal S7 to a reference current signal S3, and generates a binary signal S9 by the comparison between the additional signal S8 and an actual current signal S1.  Moreover, this generates a signal S11 which gets on low level L each time the signal S9 starts up and gets on high level each time it comes to take reference chopping timing by a flip flop 17, and this inputs a binary signal S4 which gets on high level H during the current application to the coil 1 and the signal S9 into an AND gate 15, and inputs the output signal S10 and a signal S11 into an AND gate 18 so as to generate a signal S12, and then this generates a signal S13 to operate a switching element 4 by this signal S12 and the reference chopping timing signal S6.
