Title: Frame type atomic absorption spectrophotometer
Inventor: SAKAI MASUMI
IPC: G01N21/31
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive and compact device which dose not need a power source in another system by using a phototransistor for a sensor for monitoring flame. SOLUTION: When flame is ignited, a phototransistor 21 turns into an on- state. Then as a collector current is passed through a load resistance, a collector terminal turns into a low level. Reversely, when flame is not present, the phototransistor 21 turns into an off-state and the collector terminal turns into a high level. As the collector terminal of the phototransistor 21 turns into a high level when frame is not ignited or blown out due to imperfect adjustment to the flow rate of gas, etc., signals from the collector terminal are sent to a microprocessor 1 through an input circuit 2. The microprocessor 1 closes a solenoid valve 11 for combustion gas and a solenoid valve 12 for supporting gas to halt the supply of gas.

Title: Coding period setting system for picture compression processing
Inventor: SAITO YOSHIHIRO
IPC: H04N1/411
Filed: 1988-07-16
Abstract: PURPOSE:To reduce a time required to generate a coding data by dividing each line into coding periods and applying the coding processing for each period. CONSTITUTION:Split candidate points are decided based on a difference of gradation between adjacent picture elements in each line in the direction X. When a difference between the maximum gradation and the minimum gradation between split candidate points is larger than a reference value or the distance between split candidate points is larger than the reference value, the split candidate points are deleted sequentially and when the distance between the selected split points exceeds the reference value, the split points are sequentially added. Thus, the time of coding data generation is reduced and number of parameters required at coding is reduced and the number of the bytes of coding data is reduced in comparison with the case when no section split is applied.
