IPC: H01L29/06
Filed: 1994-02-28
Abstract: PURPOSE:To enhance a vertical type MOS semiconductor device in breakdown strength without increasing it in ON-state resistance by a method wherein an outer-most peripheral body region surrounding a diffusion region of a cell section is connected to the source electrode of the cell section through the intermediary of a resistor. CONSTITUTION:A body region 13 is provided as an outer-most region surrounding a diffusion region 6 of a cell section and connected to a source electrode 9 of the cell section through the intermediary of a resistor 20. By this setup, when a reverse voltage is applied, a leakage current occurring at the junction of the outer-most peripheral body region 13 and a drain region 14 is made to flow to the source electrode 9 through the intermediary of the resistor 20 connected to the body region 13. A potential difference is produced in the resistor 20 by the leakage current in accordance with an Ohm's law and made to lessen a reverse bias voltage applied to a PN junction of the body region 13 and the drain region 4. Therefore, a vertical MOS semiconductor device of this constitution is increased in breakdown strength by a potential difference produced by the resistor 20.

Title: Phase synchronizing circuit
Inventor: FUKAGAWA TAKESHI
IPC: H03L7/06
Filed: 1990-02-09
Abstract: PURPOSE:To attain phasing in a short time even if phase difference between an intra-office clock and an intra-device clock is large by adding an out-of- synchronism detecting part and a frequency dividing part with a load signal to a synchronous clock generating part and a phase control part. CONSTITUTION:Output from a phase comparator 22 whose value is three times in succession is fetched successively to a 3-bit shift register 31 by using derivative output obtained by differentiating a reference clock(RCK) by a differentiation circuit 21, and terminals Q1 to Q3 become 1. On the other hand, after the differential output is converted into the differential output synchronizing with the output of a selector 12 by a flip flop 36, it is supplied to a frequency divider 41 as a load signal through an AND gate 35 a turned ON. When the rising-up point of RCK is delayed later than the rising-up point of an output clock three times in succession, the load signal is sent from the out-of-synchronism detecting part to the frequency divider 41. Then, the frequency divider starts counting operation from a load value set beforehand, and the output of the frequency divider and the rising-up point of RCK coincide nearly with each other, and become a synchronous state.

Abstract: PURPOSE:To enable to control while confirming the attracted condition of paper by a  method wherein the second control member is inserted from the direction perpendicular  to the first control member and its eccentric part is engaged with a free end part of  the first attracting device, in a paper feeder of a sheet fed type printing press or the  like. CONSTITUTION:The inclination of the first attracting device 26 at the time of starting  operation or the like is controlled as follows. When the machine is operated and a  transverse control knob 24 is rotated while observing the attracted position of the  paper, a nozzle support 23 is rotated and the device 26 is inclined in the transverse  direction to control the angle of inclination. In addition, when a forward-backward control knob 42 is rotated, a control shaft 43 performs an eccentric motion under the  eccentricity between the axis of a boss part and that of the shaft 43, a guide nozzle 27  engaged at a U-shaped groove 44 is inclined in the forward-backward direction, and  the forward-backward inclination of the device 26 is controlled. Therefore, the paper  22 is moved upwards in accordance with the inclination when being attracted by the  suction port 35, so that the position of the paper to the second attracting device is corrected and the paper is brought into tension by stretching in the width direction.  Accordingly, the inclination of the paper can be controlled speedily and appropriately.

Title: Partial speed change method and device for simultaneously running plural yarns
Inventor: NAGASAWA HIROSAKU
IPC: B65H51/005
Filed: 1986-02-17
Abstract: PURPOSE:To enable yarns to be fed with the speed different from other yarns by freely putting a yarn(s) of at least arbitrary one among yarn group, on rolls, and running same without contact with at least one roller of roll type yarn feed device. CONSTITUTION:When yarn group 3a remained on a net conveyer 1 much than other yarn groups 3b and 3c is sensed, contact of yarn 2a to be pulled out with one roll 81 of a yarn feed device 8 is prevented automatically or manually by a freely rotating roll 7. With this arrangement, the overall contact length of the yarn 2 with the roll of the yarn feed device 8 becomes shorter than other yarns, and the winding force therefore becomes greater in rear step to cause a slight sliding motion, enabling the yarn to be fed in a slightly speedy manner. Then, when the tip end of the yarn group 3a retreats to the allowable position, the yarn 2a is transferred from the roll 7 to the roll 81. Thus, costs for facility and operation can be reduced much than the method wherein yarn feed devices are arranged for respective yarns.
