Title: Acoustic reproducing device
Inventor: OKI SHINICHI
IPC: H04R3/04
Filed: 1986-01-27
Abstract: PURPOSE:To dissolve the shortage of a very low-pitched sound in a small scale speaker by dividing an input signal to a low-pitched sound area part and a medium and high-pitched sound area part, and performing a power amplification inserting a logarithm compression type amplifier circuit to the low-pitched sound area part, and mixing the low-pitched sound area part with the medium and high-pitched sound area part. CONSTITUTION:The input signal is divided into the medium and high-pitched sound area part and the low-pitched sound area part with an HPF1 and a BPF2, and the output of the HPF1 is amplified at a linear amplifier 5, and the output of the BPF2 is inputted to a logarithm compression amplifier 3. The amplifier 3 is operated in such a way that, in a signal having a level below a reference level where the gain of an output becomes 1, the lower the level of the signal is, the higher the amplification degree of the amplifier 3 is relatively, and in the signal having the level higher than the reference level, the higher the level is, the lower the amplification degree is, and it is operated as a limiter against a high input level. The output of the amplifier 3, after passing an LPF4 having a cut-off frequency of 150Hz, is inputted to a mixing circuit 6, and is mixed with the output of the amplifier 5, then being power-amplified and outputted. When a signal level is low, a sound volume in the low-pitched sound becomes large relatively by a non-linear characteristic in the input/ output characteristic of the low-pitched sound area part, and an auditory sense correction can be performed.

Filed: 1990-01-25
Abstract: PURPOSE:To reduce the fluctuation of the frequency of an output signal by repetitively comparing the frequency of the input signal in a period set much longer than a specified cycle, comparing the summed result with a set value and controlling the counting state of an up/down counter. CONSTITUTION:A signal (a) is outputted from an oscillation means 3 in a cycle T1 and inputted in the up/down counter 4. A signal (c) is inputted in a counter 13 from a clock oscillator 12 and the signal (c) is reset every cycle T2 in the cycle T1 every time a signal (b) in the cycle T2 is added to the counter 13 from an input terminal 1. Every time the frequency of the input signal, that is, the cycle T2 changes, the output of the counter 13 changes. The up/down counter 14 sums up the results compared by a comparison means 7 and a comparator 16 compares the summed result with the set value of a limited value setting means 15 to control the counting state of the counter 4. Thus, the fluctuation of the frequency of the output signal from an output means 5 is reduced and the control of tape traveling with small fluctuation of the cycle is accomplished.

Title: Weight sensor device
Inventor: TANAKA SHINGO
IPC: G01G3/14
Filed: 1987-01-26
Abstract: PURPOSE:To improve impact strength and noise resistance characteristics by utilizing a sheet type pressure-sensitive element and interposing an impact absorbing member and a highly conductive member between this sheet type pressure- sensitive element and a load placing member. CONSTITUTION:A weight sensor device 10 is assembled including the sheet type piezoelectric element 12, impact absorbing member 13, and highly conductive member 14 in addition to the load placing member made of a roller 11. When a turntable rotates and the roller 11 as the load placing member passes on the member 14, the weight of food and the turntable becomes a load on the member 14 and is transmitted to the element 12. At this time, even if the roller 11 contacts the member 14 impulsively, the member 13 absorbs the impact, so the impulsive load is not transmitted directly to the element 12. Further, even if an electromagnetic wave is projected to illuminate the part of the device 10 during measuring operation, the member 14 cuts off it effectively, so the device 10 does not malfunction.
