Title: Semiconductor memory
Inventor: SATO TOSHIHIKO
IPC: G11C11/406
Filed: 1988-03-22
Abstract: PURPOSE:To reduce the power consumption of a semiconductor memory by providing a refreshing period control circuit which controls the refreshing period of a refreshing period generating circuit based on the output of a memory cell for decision. CONSTITUTION:A sense amplifier 9 for decision amplifies a very weak signal from a memory cell 8 for decision to a usually used level and a refreshing period control circuit 10 changes the refreshing period of a refreshing period generating circuit 11 in accordance with the output of the sense amplifier 9. A refresh mode selector 12 switches refreshing operations between the refreshing operation to be performed in response to a refresh signal REF from the outside and the refreshing operation to be performed in response to the output of the refreshing period generating circuit 11 based on a refresh mode signal RFM. Since the refreshing period is controlled to a value close to the storage holding time of the memory cell 8 for decision, the electric power consumed by the refreshing operation can be reduced.

Filed: 1990-03-19
Abstract: PURPOSE:To improve the knowledge refining efficiency by tracing a decision tree and a sorting tree for inspection of the conclusion drawn with combination of conditional values and updating the knowledge after designing the undesigned conditional value or adding the conditions. CONSTITUTION:When a user 8 inputs a question to a knowledge base system 1, an inference mechanism 5 performs the inference processing based on a generated decision tree 12 and draws a conclusion. An example arrangement part 13 generates a sorting tree 19 from the examples stored in an example base 6. A knowledge refining mechanism 4 performs comparison between both trees 12 and 19, i.e., the knowledges stored in a knowledge base 3 and detects four patterns. For instance, the tree 19 contains the combination of the conditional values included in the tree 12 and at the same time the conclusion drawn by the relevant combination detects a pattern included in the tree 12. Thus a conclusion adding part 15 shows the corresponding combination of conditional values stored in the tree 19 to the user 8 to instruct the user 8 to input the information on the definition of conclusion for addition of conditions to a conclusion definition knowledge 11 and the tree 12. As a result, the knowledges are freeely extracted out of the examples.

Title: Interval photographing device
Inventor: KAZUMI JIRO
IPC: G03B17/40
Filed: 1985-04-02
Abstract: PURPOSE:To eliminate defects of conventional devices by performing shutter releasing operation on the end of a photographic cycle when an exposure time becomes longer than a set interval time and completing interval timer photography when exposure up to a final frame is completed. CONSTITUTION:When exposure is performed for a longer time than a set interval time, an LED 13 performs warning operation and the shutter is released at every time film winding operation is completed, i.e. at every cycle of photography. When the final frame of a film in the camera is exposed completely, the film is not advanced after the exposure, so a latch 6 is never reset after being set with the output of a counter 2; and the output 21-2 of a control circuit 21-2 is held at 'L', so the count state of a counter 3 is maintained continuously in this state and 'H' is sent out from its output Q2. Therefore, a latch 5 is reset in this case and counters 2 and 3 and the latch 5 are reset to finish photography in which an interval time is used.

Abstract: PURPOSE:To prevent the quantity of light from decreasing owing to overcooling by controlling a voltage applied to the driving motor for a fan for cooling a light source so that the voltage is high when the quantity of light of the light source is large or low when said quantity is small. CONSTITUTION:A signal generation part 20 sends out a light quantity control signal for a halogen lamp 8 according to the overexposure or underexposure of a film original. This signal is sent to a 1st power source part 17A and a 2nd power source part 17B and when the film original is overexposed, the output voltage is so controlled as to rotate fans 15 and 16 speedily according to the indication of the signal while the light quantity of the halogen lamp 8 is increased. Further, when the film original is underexposed, the output voltage is so controlled as to rotate the fans 15 and 16 slowly while the light quantity of the halogen lamp 8 is lowered. Consequently, even when the light quantity of the light source is lowered and light is projected on the film original for a long time, the light quantity of the light source is prevented from decreasing.
