Title: Gate drive circuit for igbts connected in parallel
Inventor: KITANI TAKESHI
IPC: H02M1/08
Filed: 1993-12-01
Abstract: PURPOSE:To eliminate unbalance of collector current among IGBTs by collecting the reciprocal lines of gate current being fed from a gate drive circuit to the IGBTs and passing the collected lines through a central hole of a ring core thereby preventing the displacement current from flowing to the ground. CONSTITUTION:A first gate wire 11 and a first emitter wire 12 connecting a gate drive circuit 5 and a first IGBT 10 are passed through the central hole of a first ring core 13. Consequently, the gate current reciprocating between the gate drive circuit 5 and the first IGBT 10 has a constant value thus preventing the displacement current from flowing to the ground. Similarly, a second gate wire 21 and a second emitter wire 22 between the gate drive circuit 5 and a second IGBT 20 are passed through the central hole of a second core 23, a third gate wire 31 and a third emitter wire 32 between the gate drive circuit 5 and a third IGBT 30 are passed through the central hole of a third core 33 thus preventing the displacement current from flowing to the ground.

Title: Cassette for ribbon
Inventor: SUZUKI TARO
IPC: B41M5/382
Filed: 1993-11-05
Abstract: PURPOSE:To perform a stable serial print without sticking and zigzag print, by so setting a drawing force of a ribbon when the ribbon is drawn at a predetermined speed to a specific range as to form an angle of 45 deg. to a line for connecting center of rotary shafts of two spools. CONSTITUTION:In order to draw a ribbon 4 from a cassette body 2 by rotating a spool 3b of a cassette 1 for a ribbon, a force which is larger than total sum of frictional forces of respective parts is required. Then, the case where it is actually mounted in a printer is presumed, and a drawing force when the ribbon 4 is drawn from the cassette body 1 at a speed of 100m/sec in a direction of an arrow C is set to a range of 7-14g. In this case, if the force is less than 7g, supply of the ribbon 4 becomes excessive, and a zigzag print occurs, and hence is not preferable. If the force exceeds14g. supply of the ribbon 4 becomes insufficient, and hence preferable printing is not conducted.

Title: Method for cleaning photomask
Inventor: HOSHINO EIICHI
IPC: G03F1/82
Filed: 1989-11-20
Abstract: PURPOSE:To prevent the occurrence of defects on a photomask due to unsatisfactory rinsing by fixing the point of time when rinsing is finished on the basis of the point of time when a prescribed measured value is shown. CONSTITUTION:When a photomask is soaked in a chemical soln. and the soln. sticking to the photomask is removed by rinsing with pure water to clean the photomask, the soln. is previously colored. The intensity of light passing through the waste water after rinsing is successively measured and the point of time when rinsing is finished is fixed on the basis of the point of time when a prescribed measured value is shown. A colorant is previously added to the colorless transparent chemical soln. to reduce the light transmissivity and the photomask is washed with the soln. and rinsed with pure water. The soln. sticking to the photomask is brought in a rinsing vessel and the light transmissivity of the pure water is reduced by slight coloring. The quantity of light passing through the waste water overflowing the rinsing vessel is successively measured, the point of time when the quantity of light becomes equal to that passing through pure water is regarded as the point of time when substitution for pure water is completed and rinsing is finished. The occurrence of defects on the photomask due to unsatisfactory rinsing can be prevented.

Title: Method and device for transmitting id code of remote io
Inventor: HARA KENJI
IPC: H04Q9/00
Filed: 1994-11-09
Abstract: PURPOSE: To smoothly exchange data by surely identifying their ID codes of respective IO between a master station and a slave station by transmitting the ID codes and data from the slave station at suitable timing even without CPU. CONSTITUTION: From the start of transmission, the master station sends the remote IO code fixed times. After an initial reset signal/RES is changed from an L level to an H level, an N-th slave station counts the number of signals SAMP completely transmitted from the master station by using a counter 210 and sends the ID code together with the 90H of a response RSP up to the N. When the count becomes N, a gate composed of NANDs 212 and 213 and a NOR 214 passes data from shift registers 205, 207 and 209 differentially from up to the moment so that an input data sequence can be sent to the master station together with a response RSP01H. Corresponding to the response at the head of the returned ID code, the master station judges that it is the data of a target IO. Thus, the input data can be suitably transmitted from the slave station to the master station without CPU.
