Filed: 1987-02-24
Abstract: PURPOSE:To prevent problems, such as abrasion powder, a reduction in vacuum degree from occurring by generating a varying magnetic field at a material to be treated, such as a substrate by means of a coil for uniform irradiation of plasma stream on the surface to be treated. CONSTITUTION:A magnetic field is generated by a plasma generating coil 16 in a plasma generation chamber 14, a microwave introduced into the chamber 14 is resonated with an electron cyclotron motion generated by the magnetic field, thereby generating a plasma. The generated plasma becomes a plasma stream by the divergent magnetic field of the coil 16 to flow toward a substrate 26. Since a varying magnetic field is generated at the periphery of the substrate 26 by varying magnetic field generating coils 28, 30, the magnetic field generated by the coils 28, 30 is varied at the periphery of the substrate 26. Accordingly, the quantity of the plasma applied to the surface to be treated of the substrate 26 is averaged at the respective positions, and uniformly distributed on the whole surface. Thus, the processing speed of the substrate 26 is averaged to obtain a uniform processing accuracy.

Title: Brake actuator
Inventor: JIYON KEEPU
IPC: F16D65/18
Filed: 1982-03-15
Abstract: In a brake actuator device having a fluid pressure actuated service brake and a spring-applied, fluid pressure released auxiliary brake that cooperates with the service brake via a friction clutch mechanism, there is provided a manual release mechanism for releasing the spring-applied brake in the absence of fluid pressure. The manual release mechanism operates to relieve the tension of the actuating spring by causing the piston through which the spring operates to engage a stop formed on the casing of the brake actuator device, so that the spring is caged at its opposite ends by the casing of the brake actuator device. Extension of a retracting screw to initiate the manual release operation is automatically retracted following engagement of the spring piston with its stop to reset the manual release mechanism in readiness for a subsequent operation.

Title: Method for shaping resist pattern
Inventor: KIMIZUKA MASAKATSU
IPC: H01L21/3065
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a oxide film on the surface of GaAs by shaping a resist pattern by performing plasma treatment using sulfur hexafluoride. SOLUTION: A resist pattern 6 is etched by several tens of nanometers in thickness by the RIE method using sulfur hexafluoride (SF6 ) as an etching gas. When the plasma treatment is performed, a slope part 6a in the lower section of the resist pattern is removed and the pattern 6 is formed on a vertical sidewall. In the plasma treatment, the etching is performed by adjusting the flow rate of the SF6 gas to 40 sccm, pressure of the gas to 20 Pa, and RF power to 100W. The etching rates of the resist and GaAs under the above- mentioned etching condition becomes 550Å/min and 30Å/min, respectively. The hemming bottom 6a of the pattern 6 is removed by performing the plasma treatment for about one minute under the above-mentioned condition.  Therefore, the etching can be performed without deteriorating the etching rate and nor roughening the surface at the time of etching a GaAs layer in the succeeding process, because the resist pattern can be shaped without oxidizing the surface of the GaAs layer.

Title: Binder for toner
Inventor: OCHIAI SHIGEO
IPC: C08F257/02
Filed: 1988-02-23
Abstract: PURPOSE:To facilitate electric chargeability control, to reduce dependence on environmental conditions, to lower a fixable lowest temperature, and to obtain a binder durable to high heat roll temperature by using a polymer wide in molecular weight distribution for the binder and heat polymerizing monomers without using any polymerization initiator. CONSTITUTION:The binder resin having a molecular weight of 5,000-50,000 and a wide molecular weight distribution is obtained by heat polymerizing a styrene type monomer and a (meth)acrylic monomer by heating them to a temperature higher than the temperature substantially initiating heat polymerization by >=50 deg.C and lower than 250 deg.C in the substantial absence of a polymerization initiator. It is preferred to control the styrene type monomer content to 90-70wt.% of the total monomers, and if <65wt.%, a temperature causing offset over the heat roll becomes lower, and if over 95wt.%, the fixing lower limit becomes too high. The wider the temperature width between the offset causing temperature and the fixable lower limit, the more preferable heat characteristics as the toner, thus permitting the obtained toner to be facilitated in chargeability control and lowered in environmental dependence.

The compounding ratio of PMMA and polypropylene is not important and 2-50wt% rubbery material is favorably mixed into the resin.
