Title: Telescopic stepladder
Inventor: YASUNAGA KAZUO
IPC: E06C7/06
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To allow various operations at high positions to be done easily and safely. SOLUTION: A pair of telescopic stepladder members 10 are pivotally connected together at their tops, each of the telescopic stepladder members 10 including a pair of side rails made of plural pipes slidably joined together and differing in diameter, a rung member attached to the tip of each of the pipes forming the pair of side rails 1, and a release-mechanism-equipped lock mechanism 14 which can lock the pipe of each side rail in an extended position. Therefore, even if working height varies, a step 10b is held at a predetermined height by expansion/contraction of the telescopic stepladder members 10 and can be firmly locked at that position by the release-mechanism-equipped lock mechanism 14, so that the operator can do various operations easily and safely.

Title: Method for elimination non-reaction gas within reduced-pressure vapor growth device
Inventor: HOSAKA HIROSHI
IPC: H01L21/205
Filed: 1991-10-15
Abstract: PURPOSE:To enable the number of particles which are adhered to a wafer to be reduced by taking wafers which were subjected to vapor growth treatment out of a reactor and by repeating evacuation, oxygen replacement, or inactive gas replacement for a plurality of times repeatedly. CONSTITUTION:Evacuation is performed after placing a wafer into a reaction reactor, a reaction gas is introduced after an atmosphere is replaced by nitrogen, and then, for example, a polysilicon film is allowed to grow on the wafer. After formation of film is completed, the atmosphere is replaced by oxygen again, atmosphere is recovered, and then the wafer is taken out of the reactor. Then, evacuation and oxygen replacement process are repeated for a plurality of times and then an inside of the reaction reactor is returned to the atmosphere. Repetition of this oxygen replacement eliminates a non-reaction gas within the reaction reactor and can reduce the number of particles which are adhered to the wafer drastically.

Title: Arithmetic control method for speed
Inventor: MATSUI MITSURU
IPC: G01P3/56
Filed: 1987-10-21
Abstract: PURPOSE:To detect an abnormal state speedily by maintaining a control state with a speed-predicted value when detecting a speed-detected value which is one cycle before being abnormal and outputting a cancel signal to a controller when abnormal values are successive. CONSTITUTION:A speed-recognized value Vn in the current cycle is calculated, acceleration alphan-1 stored in a memory M1 in a previous cycle is shifted to a memory M2 so as to become acceleration alphan-2 which is two cycles before, and the acceleration alphan in the current cycle stored in a memory M is set to alphan-1. Then the speed difference DELTAV between the last cycle and current cycle and the acceleration alphan are calculated. This alphan is stored in the memory M as the acceleration in the current cycle. When it is judged that this speed difference DELTAis larger than a reference value Vr, it is judged that the speed-detected value in the current cycle is abnormal and a speed predicted value Vp is calculated in this case and regarded as a recognized value Vn in the current cycle. Further, when the speed difference DELTAV larger than the reference value Vr is generated repeatedly, it is judged that is not caused by an instantaneous abnormal state such as noise and cancellation is performed so as to preclude misdetection.
