IPC: H03G11/08
Filed: 1992-12-22
Abstract: PURPOSE:To provide an audio signal correction circuit in which a small sound is easily heard in the case of the presence of background noise without causing hard of hearing of a large sound. CONSTITUTION:After a low frequency component and a high frequency component of an input sound signal 100 whose dynamic range is compressed by a compressor circuit 1 are boosted at a frequency correction circuit 2, the result is attenuated at an attenuator circuit 3 and the result is inputted to an adder circuit 5. Simultaneously the input sound signal 100 is attenuated by an attenuator circuit 4 and inputted to an adder circuit 5. The adder circuit 5 sums signals inputted from the attenuator circuits 3, 4 and outputs the sum as an output sound signal 200. As a level of the input sound signal 100 decreases, the correction in which the dynamic range of the output sound signal 200 is compressed and the low and high sound frequency components are boosted is executed.

Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To surely prevent the sticking of dust even in a dusty spot by recovering stagnant oil to an oil tank via a filter device and applying oil in the oil tank to a driving chain from the upper part of a case for circulatory use. SOLUTION: Oil is supplied by a pump 20 through tubes 21 to 23 to hermetic cases 15, 52 and 53 and applied to a driving chain 2. Thus, gears 41 and 42 and the chain 2 are lubricated with oil, superfluous oil is caused to stay in the bottom parts of the cases so as to form a stagnant oil part 8 and the gears and the chain are cleaned. Further, oil from the stagnant oil part 8 is pulled out at constant intervals by opening valves 12 to 14, recovered into an oil tank 25 and circulated repeatedly. Thus, since the gears and the chain inside hermetic type chain cases 51 to 53 are not exposed to dust, the wearing of the chain is reduced.

Title: Microwave oven
Inventor: MINAGAWA HIROSHI
IPC: F24C7/02
Filed: 1991-12-26
Abstract: PURPOSE:To enable the weight of food placed on a turn-table tray to be accurately calculated without having any relation with the positional relation of the food. CONSTITUTION:A projection 8 is arranged at a bottom surface of an oven 7, and a supporting roller for supporting a turn-table tray passes through the projection. As the tray 1 is controlled under its rated speed, driving torque of the motor 2 becomes the value corresponding to the weight of the food placed on the tray 1. Then, the driving torque is varied as the supporting roller 6 passes through the projection 8 and its varying pattern is varied in response to the positional relation of the food. However, the mean value of the driving torque during one rotation of the turn-table tray is assumed to be substantially constant without having any relation with the arrangement if the weight of the food is kept same. Logic calculation control circuit 15 calculates the mean value of the driving torque from the control data attained by the motor driving circuit 14 and further calculates the weight of the food in response to it.
