Title: Electrolytic solution for driving electrolytic capacitor
Inventor: ASADA KOJI
IPC: H01G9/035
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To suppress the rise in specific resistance and to improve breakdown strength by adding polyvinyl alcohol polyethylene glycol graft compound to electrolytic solution for driving an electrolytic capacitor. SOLUTION: Polyvinyl alcohol polyethylene glycol graft compound represented by the formula is added to driving electrolytic solution which is obtained by dissolving high class dibasic acid or the ammonium salt, boric acid or the ammonium salt in solvent, where ethylene glycol is made to be the main component. At this time, weight percent is set so that polyvinyl alcohol: polyethylene glycol= about 1:1-20:1. The polymerization degree (n) of the polyvinyl alcohol is set to from about 200-1,500 and the polymerization degree (m) of polyethylene glycol is set from about 4-800. Moreover the added amount is set from about 0.1-10.0 weight %. Thus, the rise of specific resistance is suppressed, and withstand voltage is improved.

Title: Reactive ion etching device
Inventor: IWASAKI KENYA
IPC: H01L21/302
Filed: 1990-08-30
Abstract: PURPOSE:To prevent the corrosion of an etching pattern due to a reaction product by forming an upward inclined lower variable electrode around a lower electrode and askew changing the incident angle of ions. CONSTITUTION:An upward inclined lower variable electrode 12 is formed around a lower electrode 8. The lower variable electrode 12 is also made horizontal and etched in the same manner as the lower electrode 8 on normal etching. A reaction product 21 adheres to the sidewalls of an etching pattern 22 at that time. When the lower variable electrode 12 is inclined upward, ions are pulled by the ion sheath of the surface of the lower variable electrode and bent obliquely, and collide with a slant semiconductor wafer 9. Consequently, the reaction product 21 adhering to the sidewalls of the etching pattern 22 can be removed. Accordingly, the corrosion of the etching pattern 22 can be prevented.

Title: Bush chuck
Inventor: MASUDA HIROKATSU
IPC: B23B13/12
Filed: 1989-09-01
Abstract: PURPOSE:To accurately grip and hold an axis center of a workpiece of a material having a modified shape of a polygonal section by forming a plurality of cut slit parts for expansion/contraction in a zigzag form such as a polygonal line, which extend in the axial direction and communicate with one end surface of a cylindrical body of a bush chuck such as a collet chuck. CONSTITUTION:After a workpiece is inserted into a super hard part 21, a pressing body fitted on an outer periphery side of a bush body 11 is pressed from behind toward a tapered surface 14 to compress a forward end side of te bush body 11 inward in the diametrical direction to contract the diameter thereof to hold the workpiece with the super hard part 21. At the time of holding, even if the workpiece is of a rod type material having a modified shape of a polygonal section such as a hexagon, entering of an edge line part of a straight line form of the workpiece into a slit part 22 is prevented, since the cut slit part 17, 22 for expansion/contraction is of a polygonal line form. Every edge line part of the workpiece is thereby in contact with an inner peripheral surface of the super hard part 21, the axis center thereof is always consistent with that of the bush body 11, and the workpiece is therefore uniformly and firmly compressed and tightly held.

Title: Facsimile terminal equipment
Inventor: ASANO TOSHIO
IPC: H04N1/04
Filed: 1982-12-28
Abstract: PURPOSE:To perform accurate partial transmission based upon partitioning positions of a fixed-format transmission original by collating partitioning position information on the fixed format of the transmission original with position information obtained by detecting a mark set by an operator. CONSTITUTION:When a detecting element 6 detects the mark 3 as the position setting means of the transmission original 1, a counting circuit 8 starts counting pulses. Then, when the element 6 detects a cursor 4a, a circuit 7 sends a cursor detection signal to the circuit 8, whose current counted value is sent out as position information to a comparing circuit 10. The circuit 10 compares the counted value with the partitioning position information stored in a memory 9 for the partitioning position of the fixed format to calculate their difference. This difference signal is compared by a circuit 11 with a specific value, and when this difference exceeds the specific value, this position information is stored in a skip-read position memory 12. A pulse motor control circuit is driven on the basis of the information in this memory 12 to make a skip read of the original 1.

Abstract: PURPOSE:To perform safer and surer assist control by stopping the assist control by stopping generation of assist torque through a motor, when an abnormal condition, where a mean value of output signals of main and sub torque sensors are shifted from a reference value, is continued for a predetermined time. CONSTITUTION:In an electrically-operated power steering device, assist torque to assist is drawn out by a control circuit 11 based on an output of a torque sensor 6 and a car speed, and assist control of steering is performed by setting a driving current of a motor 7. The torque sensor 6 comprises a main torque sensor 21 and a subtorque sensor 22 having equal characteristic, and both the torque sensors 21, 22 are connected in a condition of reverse polarity to each other to positive and negative terminals 23a, 23b of the same DC power supply. Here in the control circuit, a mean value of each sensor output is calculated, and in the case that this mean value is not equal to a reference value, any abnormality is judged generated to compare a count value Fc of a fail counter with a preset value Q. When decision for whether a relation is Fc<Q or not is NO, the assist control is stopped.

Title: Laser oscillation control device
Inventor: WATANABE YOSHIYA
IPC: H01S3/131
Filed: 1991-09-09
Abstract: PURPOSE:To perform stabilized laser output control by eliminating the deviation of an output measurement from an output setting due to delayed response of a detector. CONSTITUTION:A laser control device includes a delay circuit 7. When the output level setting is changed manually, the delay circuit temporarily stops an output stage from producing an optical feedback compensation signal. This prevents the laser power source 5 from receiving the compensation signal for the apparent difference between the laser output and the output setting due to a delay time of an optical sensor 1. During operation of the delay circuit 7, open loop control continues, but the delay time is small enough to avoid the problem that laser output fluctuates with time. This laser control device serves to eliminate the overshooting and delay of laser output due to the delay of response in a detector.

Title: Vertical linearity correction circuit
Inventor: TANAKA TOSHIAKI
IPC: G09G1/16
Filed: 1988-09-12
Abstract: PURPOSE:To prevent scanning lines in pair at the lower part of the screen by clamping a parabolic wave obtained through the integration of a saw tooth wave with a vertical deflection period at a prescribed level near the vertical blanking period so as to bend a vertical deflection current waveform into the S shape. CONSTITUTION:A DC component is eliminated from a parabolic wave S2 outputted from an integration circuit 8 by a capacitor 9a and fed to a base of a transistor(TR) 9b. If the voltage level of the parabolic wave S2 is dropped and the base voltage of the TR is lower than a voltage Va, a diode 9e is turned off and the base voltage of the TR 9b is dropped in following the decrease in the voltage of the parabolic wave S2. Thus, the capacitor 9a is charged through a resistor 9g to be able to apply clamping even at the end of any field. Thus, the occurrence of scanning lines in pair at the lower part of the screen is avoided.
