IPC: H01L21/30
Filed: 1987-05-01
Abstract: PURPOSE:To provide higher sensitivity and higher resolution by introducing a trihalogenated acetyl group having crosslinking reactivity into the residual hydroxyl group of specific LMR. CONSTITUTION:The trihalogenated acetyl group expressed by the formula II (in the formula II, X is any among F, Cl and Br) is introduced as a radiation sensitive group at >=0.5molar fraction into the naphthoquinone diazide sulfonate (LMR) of a paracresol novolak resin expressed by the formula I. Namely, this material is formed by changing the introduction rate of the halogenated acetate of the LMR and further the naphthoquinone diazidesulfonyl group in the LMR and subjecting all of the remaining phenolic hydroxyl groups with each thereof to halogenation acetylation. The higher resolution is thereby maintained and the higher sensitivity is obtd.

Title: Driving method of induction motor
Inventor: KAJIOKA HITOSHI
IPC: H02P1/26
Filed: 1990-04-24
Abstract: PURPOSE:To share a current control system among a plurality of inverters by employing multiplex input windings in an induction motor and feeding power to each winding from individual inverter thereby obviating the necessity of quadrature current suppression. CONSTITUTION:Input windings 31, 32 of an induction motor 30 comprises coil groups wound around respective pole coils 41-44 or respective sets of a plurality of pole coils 41-44 while being insulated one another, where voltages having same phase and same amplitude are fed from individual inverters 7A, 7B to respective pole coils 41-44 or respective sets of pole coils 41-44. Since multiplexed outputs from the plurality of inverters 7A, 7B are not fed to the input windings 31, 32, quadrature current is not required to be suppressed. Consequently, the plurality of inverters 7A, 7B do not require a current control loop for controlling DC component, i.e., the quadrature current, and the inverters 7A, 7B can be controlled through a common current control system.

Title: Generating method for excess error alarm
Inventor: KUWANO HIRONOBU
IPC: H02P29/00
Filed: 1988-04-29
Abstract: PURPOSE:To detect a malfunction in which a positional error becomes excessive in a short time even if the rotating speed of a motor is low by generating an alarm when the ratio of a speed deviation to a command speed exceeds a set value. CONSTITUTION:A digital servo circuit 1 calculates a positional error of the difference between a command moving amount and an actual moving distance, and generates a command speed VCMD on the basis of the error. A servo motor 4 is controlled on the basis of a speed deviation EV of the difference between a command speed and an actual speed. On the other hand, an excess error detector 2 calculates the ratio of the deviation EV to the speed VCMD at each predetermined time, monitors it and generates an alarm SALM when the ratio exceeds the set value. Thus, even if the rotating speed of the motor is low, the generated malfunction can be detected in a short time.

Title: Static eliminating method and static eliminator for liquid having high specific resistance

Filed: 1993-04-09
Abstract: PURPOSE:To prevent the elution of metallic ions by providing an insulation layer to allow the passage of tunnel current on the surface of a conductor member kept in liquid contact with pure water or liquid having high specific resistance used in the manufacture of an element weak in resistance against static electricity, when the static electricity is eliminated therefrom. CONSTITUTION:When pure water 1, for example, is sprinkled on a treated material 11 weak in resistance against static electricity for a washing purpose, the pure water 1 fed thereto is kept in contact with the material 11 via a laminated tube consisting of a member 3 of conductor and a resin tube 4. In this case, an insulation layer to allow the passage of tunnel current is formed on the surface of the member 3 and connected to a power supply 10 via a conductor 5. The member 3 is thereby kept at the prescribed potential. In this way, a relationship between piping application potential applicable to the member 3 and surface potential due to static electricity generated in the material 11 sprinkled with the pure water 1 is linearly established as shown in the figure. In other words, it is seen that the surface potential of the material 11 can be kept at zero, when the potential of the member 3 made of a conductor is kept approximately at 100V.
