Title: Radiation combustion stove
Inventor: KOBA YOSHITAKA
IPC: F24C1/14
Filed: 1983-11-11
Abstract: PURPOSE:To make it possible to uniformly obtain high-temperature radiant heat radiation effective for heat collection in a large amount and on the entire surface with a simple construction by alternately arranging small diameter parts and large diameter parts, providing slant surface parts between the small diameter parts and large diameter parts, and dispersedly providing small holes for discharging combustion gas on the slant surface parts. CONSTITUTION:Small diameter parts 6 and large diameter parts 7 are arranged on a combustion cylinder 5 alternately and repeatedly in the vertical direction, and small holes 9 for discharging combustion gas formed on the slant surface parts form a zigzag shape at the upper stage and the lower stage on the inner side of the combustion cylinder 5. Thereby, the flow layer in which the surface of the combustion gas rises up along the inner wall of the combustion cylinder 5 becomes uniform. On the other hand, on the outer side of the combustion cylinder 5, small holes 9 at the upper stage and small holes 9 at the lower stage form a similar zigzag arrangement. Hence, a gas discharged in depressions through small holes 9 and 9 hit against the slant surface plate 8, and then is diffused in a turbulent manner. Thus the high- temperature gas stays within the depressions. As a result, since the surface of the combustion cylinder 5 is encircled by a high-temperature gas atmosphere and does not undergo cooling due to external air, the surface of the combustion cylinder 5 uniformly has a high temperature and the radiant heat quantity can be increased.

Title: Reception system for push-button dial telephone data
Inventor: HARADA TAKESHI
IPC: H04L29/10
Filed: 1981-12-29
Abstract: PURPOSE:To improve the processing efficiency of a control part, by reading push-button dial telephone data at specified intervals. CONSTITUTION:A timer TIM sends an interruption signal to the control part CONT at intervals of about 100ms. On receiving this interruption signal, the CONT judges the signal as a high-level interruption and sends a readout indication to each register REG at prescribed timing to read the contents of each REG. The primarily read contents of the REG are reset. Thus, the contents of respective REGs are read by the interruption signal from the TIM to improve the processing efficiency of the CONT because the respective REGs are read at the same timing although the contents of the REGs are read conventionally according to reception timing signals of respective push-button dial telephone data receiving circuits PBR#1-PBR#3.

Title: Noise elimination method and noise elimination device for optical sensor
Inventor: HORIE IKUKO
IPC: H04N1/409
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To provide quickly image data with less noise by detecting noise based on the ratio of a discontinuous part of a power spectrum to the previous mean value so as to conduct the noise elimination processing. SOLUTION: Image data outputted from a CCD line sensor OS are given to a sample data acquisition section 1, by which image data obtained by scanning a same element in the vertical scanning direction are extracted. The image data are given to a power spectrum calculation section 2, in which a power spectrum is obtained. Then a moving mean calculation section 3 calculates a moving mean and a discontinuity decision section 4 detects a discontinuous part of the mean value. When a discontinuous part is further in existence, a ratio calculation section 5 calculates a ratio the discontinuous part to a preceding mean value, and a decision section 6 compares the calculated ratio with a preset threshold level. When the ratio exceeds the threshold level, a noise elimination processing section 7 reduces or eliminates the frequency component in the discontinuous part.

Title: Plasma etching method and apparatus
Inventor: SASAKI ICHIRO
IPC: G01R31/26
Filed: 1990-08-15
Abstract: PURPOSE:To cool a wafer to a required level and enable plasma etching at a low temperature through monitoring of the substrate temperature by making small the contact area between electrode body and other elements and using a thermometer by an optical signal. CONSTITUTION:An electrode body 2, an insulator 3 and an earth shield 4 are positioned and fixed to form an electrode. Therefore, the contact surfaces 13 and 14 are not always required to be contact at total area but only the area required for positioning must be in contact and unnecessary area is cut away for avoiding the contact condition. Thereby, the total contact area can be reduced by about 30%. As a result, quantity of entering heat can also be reduced by about 30%. Moreover, a fiber 23 of a phosphor thermometer is fixed to the electrode body 2 with a fixing means 24 to monitor temperature of wafer and feeds information back to a freezer. Thereby, temperature change during processing of wafer can be lowered. Accordingly, a wafer may be cooled to a low temperature and temperature may be monitored during the etching. As a result, highly accurate etching may be realized with high reproducibility.

Title: Speed change control device for toroidal continuously variable transmission
Inventor: NAKANO MASAKI
IPC: F16H15/38
Filed: 1991-08-01
Abstract: PURPOSE:To provide a device to stabilize speed change control by improving the sensitivity of a speed change control valve to actuate the power roller actuator of a toroidal speed change mechanism at high speed revolutions for an improvement in damping effect. CONSTITUTION:In the case where a speed change control valve 70 is controlled through a feedback (F/B) system composed of a precession cam 121, a link 122 and a spool 73b which interlock with the movement of a power roller, the control valve 70 actuates an actuator, and F/B control is executed so as to obtain a target speed change ratio. The control valve 70 is supplied with the line pressure of an oil passage 150 as speed change control pressure, which depends upon the number of input revolutions, and increases at high speed revolutions to heighten the sensitivity of the control valve. The damping effect at the high speed revolutions is therefore improved to stabilize the speed change control even in the case of high input revolving speed at which the power roller acts quickly. A valve being little in leakage can be used as the control valve 70.
