Title: Information processor
Inventor: NONAKA NAOMICHI
IPC: G11B19/00
Filed: 1990-11-27
Abstract: PURPOSE:To automatically change a set monitoring time according to the operating state of an equipment before an energized state is turned on or off by changing the set monitoring time based on the detection result of a detector means which detects the operating state of the equipment. CONSTITUTION:A CPU 1 is provided together with a disk controller 3, a disk driver 4, a power supply controller 5, a timer 10, and a power controller 20. The CPU 1 confirms the operating state of an equipment by a detector means. If a prescribed state of the equipment, e.g., a state of a disk driver, for example, where no access is applied lasts for a monitoring time or longer, a switch means is controlled so that the energization of the equipment is turned off. If an access is applied to the disk driver under such conditions, the energization of the equipment is turned on. At the same time, the control means confirms the time when the energization is switched to an ON state from an OFF state. If such a confirmed time is longer than the monitoring time, the monitoring time is cut down by a prescribed time. Thus the power consumption of the equipment can be reduced.

Abstract: PURPOSE:To obtain the filtering method corresponding to submicron particles while suppressing an equipment scale by extracting a part of rolling oil from a circulating oil passage to filter the same by a sub-filter having filtering accuracy higher than that of a main filter to remove particles having a particle size of below 1mum and subsequently returning the filtered oil to the circulating oil passage. CONSTITUTION:The rolling oil recovered from a rolling machine 1 is entirely supplied to a main filter 3 through the first oil passage 5, a dirty tank 2 and the second oil passage 6 and particles whose particle size is up to 1mum are filtered and removed by the main filter 3. Thereafter, the rolling oil is stored in a clean tank 4 through the third oil passage 7. A part of the stored rolling oil in the clean tank 4 is extracted by an extraction pipe 10 and supplied to a sub-filter 11 to filter and remove metal particles of 0.4-1.0mum while the filtered oil is returned to the clean tank 4 through a return pipe 12. By this method, the submicron particles in the circulated rolling oil can be lowered to a tolerant level.

Title: Digital automatic gain controller
Inventor: SHINABE MUNEHIRO
IPC: H03G3/20
Filed: 1994-12-27
Abstract: PURPOSE: To realize a wide dynamic range with high stability and high accuracy by providing a 1st gain coefficient multiplier section in a pre-stage of a gain coefficient multiplier section to discriminate an output of an integration section and controlling a register of the 1st gain coefficient multiplier section and the integration section. CONSTITUTION: A 1st gain coefficient multiplier section 14 uses a multiplier 9 with overflow prevention to multiply a 2<m> derived from an integral number (m) controlled by a discrimination control section 12 with an input digital signal. When an absolute value of the output is larger than a digital maximum value processed by a 2nd gain coefficient multiplier section 1, the signal is clamped to a positive maximum value or a negative minimum value to prevent overflow. The multiplier section 1 multiplies an output value CR of an integration section 4 with an output of the multiplier 14 to control the gain. Correction is made so that an output power of the output signal from the multiplier section 1 is equal to a reference value Ref. Thus, the gain range is extended without increasing deteriorated accuracy or a quantization error.
