Title: Method of monitoring plasma etching
Inventor: FUJITA YOSHIRO
IPC: H01L21/3065
Filed: 1987-07-21
Abstract: PURPOSE:To measure the temperature and density of plasma without having effects upon the plasma by separating plasma light emitted from an observation aperture into two optical paths using a lens and a beam splitter and the like and by taking out respective specific two wavelengths of the plasma light through monochromators and multiplier phototubes, thereby monitoring the intensity of the wavelengths. CONSTITUTION:After passing through a condensing lens 3, plasma lights are separated into two optical paths and are injected into monochromators 5a and 5b and then, the plasma lights having specific wavelengths are taken out. When two optical paths of the above plasma lights are converted into electric signals through multiplier phototubes 6a and 6b, the intensity of the plasma lights in specific wavelengths which changes with time can be monitored. In such a case, if transition probability, number of oscillations, statistical weights, and excitation energy are known, the temperature of plasma which changes with time is obtained by applying Boltzmann equation. Further, if the temperature of plasma is substituted into Saha's equation which exhibits the relationship between the temperature and density of plasma, the density of plasma which changes with time is obtained.

Title: Smokeless roaster
Inventor: NAKAMATSU YOSHIRO
IPC: A47J37/06
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of smoke at the time of roasting meat and further to simplify a structure by eliminating movable parts and expendables by providing a part for making flow and removing oil out of the meat and a container for oil storage independent for storing the removed oil and cooling the oil storage. SOLUTION: When a meat 2 is placed on the heated outer surface of a roasting part 1 and roasted, oil from the meat 2 which flows out is stored in an edge fat storage 4 and enters to an oil receiver 7 from a fat outflow pipe 6. At such a time, the air current of external air 14 from a gap 13 between the edge oil storage 4 and a cooking stove 8 ascends along the inner surfaces of the roasting part and flows to a chimney 3 because of a chimney effect of the chimney 3. Thus, the part close to the edge oil storage is cooled by that cold external air current, the overheat of a roasting surface or oil flow surface is prevented and the generation of smoke is prevented. Projections for supporting the roasting part 1 on a trivet 12 are formed and arranged not to disturb the inflow 14 of external air.  Thus, the oil of the meat 2 is not thermally decomposed by the air current 14 and the chimney 3 so that smoke and smell are not generated and the cooking stove 8 is free from oil drops so that clean state is maintained.

Title: Phase locked loop circuit
Inventor: YOSHIDA KOUICHI
IPC: H03L7/10
Filed: 1992-07-09
Abstract: PURPOSE:To shorten the transient response time during which a VCO reaches a synchronous state by securing a constitution where the VCO oscillates concurrently with input of a reference signal and the DC voltage of the same level as the control voltage set in the synchronous state is supplied from a smoothing capacitor included in an LPF. CONSTITUTION:The level of the control voltage V2 supplied to a VCO 2 is set equal to the voltage VR in a phase synchronizing steady state. The inputted reference signal IN is detected by a reference signal input detecting circuit 9. The circuit 9 outputs a start signal ON to start the oscillation of the VCO 2 and switches a switch 11 to the side of the VCO 2 from the side of a DC power supply 10. Therefore the voltage VR charged into a capacitor 5 is supplied to the VCO 2 with input of the signal IN. As a result, the VCO 2 immediately outputs an output signal OUT synchronized with the signal IN regard of the frequency and the phase and can instantaneously rise to a steady state without through the a transient state.

Abstract: PURPOSE:To improve cooling efficiency as well as maintainability of an electronic device by dividing 1 space inside the electronic device frame by partitions, wherein several straight cooling air passages, and blinds whose passage resistance varies with varying temperatures are formed so that air volumes in the cooling air passages can relatively be adjusted. CONSTITUTION:When a fan 11 is operated while operating an electronic device, cooling air flows smoothly through two cooling air passages 14a and 14b of a frame 10 in the bottom-up direction, thereby cooling a component 15 by taking away heat therefrom. The air volume and air speed are adjusted by opening and closing blinds 16a and 16b. The temperatures of the cooling air heated by cooling the component 15 are detected by sensors 17a and 17b located at the outlets of the passages 14a and 14b. When the difference between both temperatures becomes large, the passage resistances are reduced by opening the high temperature side of the blinds 16a and 16b, while the passage resistances are increased by closing the low temperature sides thereof. According to the constitution, the cooling air absorbed by the fan 11 flow to the high temperature side of the passage 14a or 14b whose passage resistance is lower at a large ratio, thereby encouraging the cooling. The component 15 projects from the frame 10 by opening an opening and closing door 18, thereby providing an easy working environment.
