Title: Uninterruptible system switching method and device containing redundant constitution using the switching method
Inventor: YOKOTA KIYOSHI
IPC: H04L12/28
Filed: 1994-11-09
Abstract: PURPOSE: To provide an uninterruptible system switching method which can perform the switching of systems with no interruption and high reliability with a simple and small-scale constitution. CONSTITUTION: An uninterruptible system switching method consists of a switching control circuit 1 which performs the system switching control, a transmitting block 3 which sends the input main signals to both working and stand-by processing blocks, a 0-system processing block 5 and a 1-system processing block 7 which operate as the working or stand-by systems, and a receiving block 9 which selects and outputs one of main signals sent from both blocks 5 and 7. Then the block 3 is provided with a signal memory FIFO 32 which can store the largest number of cells that can be stored in the internal buffers of both blocks 5 and 7. Thus the idle cells are accumulated in these buffers while the main signals are stored in the FIFO 32 in a system switching mode.  So that no effective information remains in the buffers and the duplication or the omission of cells can be prevented for the switching of systems.

IPC: F25D17/06
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a temperature-controlling device for properly controlling the temperature of a food material contained in a storing chamber. SOLUTION: The atmosphere temperature (ta1 ) of a food material is derived on the basis of the change with time of a detection temperature (tb A) detected by a temperature sensor installed in a storing chamber (step 302) and the temperature (tc1 ) of the food material is derived from the atmosphere temperature (ta1 ) (step 306). The value of the derived food material temperature (tc1 ) is displayed on a food material temperature indicator (308). When the temperature (ta1 ) of the food material is lower than the lower limit (tmin1 ) or higher than the upper limit ((tmax1 ), an alarm is warned with sound (steps 310, 312).  The value (a) in the formula is a constant decided by the places on which the food material is placed and to which the temperature sensors are set in the chamber and the values C and K represent the heat capacity and the heat loss coefficient of the food material, respectively.

Title: Method for recovering zinc from iron making dust
Inventor: TOYAMA SHUNICHI
IPC: C22B7/02
Filed: 1985-12-09
Abstract: PURPOSE:To recover zinc from making dust at a high removal rate by subjecting zinc-contg. dust to a leaching treatment in a hydrochloric acid soln. to classify the dust to a zinc rich phase and zinc lean phase and extracting and separating zinc from the zinc rich phase. CONSTITUTION:The zinc-contg. iron making dust is stirred for a specified period at <=0.5pH in the hydrochloric acid soln. and is classified to the zinc rich phase in which the zinc is segregated and (<100mu) and the zinc lean phase (>100mu) in which the zinc concn. is low by a classifier. The zinc rich phase is added to a hydrochloric acid of about 10-30% concn. to a mixing ratio of about 1 (solid): 9-19 (liquid) and is extracted for about one hour at about 40 deg.C temp. A solid-liquid sepn. is executed after the extraction. The separated zinc-contg. aq. soln. is neutralized to about 8.5-10.5pH and the zinc is recovered in the form of precipitate. The solid content separated from the zinc-contg. aq. soln. and the zinc lean phase are subjected to a neutralizing treatment and are reused as an iron source. The zinc is thereby efficiently recovered from the iron making dust and the residue after the zinc extraction is made usable as a iron source for a blast furnace.

Filed: 1987-10-31
Abstract: PURPOSE:To simplify the picture reading actions by confirming the reading state of the read picture in parallel with the picture reading action. CONSTITUTION:When the display screen of a CRT 3 is smaller than the size of a read picture, a scanner 7 starts its scanning action.
