Title: Noise insulating structure
Inventor: KAMIYA TAMOTSU
IPC: F02F7/00
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a noise insulating structure capable of sufficiently reducing the radiative noise from a sounding body without largely increasing the weight. SOLUTION: A damping material 14 attenuates the vibration of an oil pan 8 by contacting therewith, and the noise in a gap 12 can be attenuated by the resonator action by a chamber 16 formed by the damping material 14 and a noise insulation cover 10 and a through hole 14e. An edge of the gap 12 is totally sealed by the damping material 14, so that the leakage of the noise in the gap 12 can be prevented. The vibration of the oil pan 8 of an area contacted with the damping material 14 can be attenuated only by mounting a sheet-shaped damping material with the approximate omega shaped cross section on a part of the gap 12, and the vibration of the oil pan 8 of an area not contacted with the damping material 14 is attenuated by the resonance by the resonator.  Whereby the radiative noise from the oil pan 8 can be sufficiently reduced without largely increasing a weight of an internal combustion engine.

Patent JP-S6271249-A (JP)
Title: Gate array
Inventor: YOSHIDA AKITO
IPC: H01L21/822
Filed: 1985-09-25
Abstract: PURPOSE:To prevent an erroneous operation from occurring without increasing an integrated circuit area by burying a capacity element for a path capacitor under a wiring region on a semiconductor substrate. CONSTITUTION:A P- or B-doped polysilicon 4 is, for example, accumulated on the entire wiring region 3, and a capacity is formed to a semiconductor substrate 1. An interlayer film uses, for example, a thermal oxide film, and the thickness is, for example, 0.5mum. This capacity becomes approx. 3nF. The substrate 1 and a polysilicon 4 are connected between power sources before master-slicing step. When the capacity for a path capacitor is thus formed, the master-slicing step can be executed by the same method as the conventional method to eliminate the decrease in the integration. Thus, it can prevent an erroneous operation without increasing the integrated circuit area.

Title: Thermomagnetic recording system
Inventor: OKAMURA SHIROU
IPC: G11B5/02
Filed: 1981-12-29
Abstract: PURPOSE:To perform excellent-S/N digital and analog recording by selectively reducing and eliminating magnetism at positively and negatively magnetized parts of a magnetic medium which is magnetized previously and periodically to positive and negative prior to local heating. CONSTITUTION:The tape which is bias-magnetized positively and negatively in a sine wave shape by a magnetic head 21 previously has positive parts 3' and 4' and negative parts 7' and 8' with distinction. This distinction is carried out corresponding to the output of a digital signal source 25 by discriminating the polarity of a preliminary recording signal 20 through a circuit 24. Therefore, positive and negative saturated magnetism remains invariably to obtain a good S/N ratio.

Title: Memory control system for bar code reader
Inventor: KAWAI HIROAKI
IPC: G06F3/06
Filed: 1986-09-05
Abstract: PURPOSE:To accumulate bar code data large in capacity at low price, by performing the read/wire of the bar code data by controlling a random access memory, instead of a FIFO memory. CONSTITUTION:When the bar code data is inputted, a timing adjusting circuit 1 outputs a write command signal, a read command signal, and a synchronizing signal with a prescribed timing. A counter circuit 2 counts the write signal, and the read signal based on the synchronizing signal, and generates a write address, and a read address one by one. The random access memory 3 writes the bar code data on the position of the write address, and similarly performs the read of the data from the read address. Thus, the memory 3 can perform the role of the FIFO memory. Therefore, it is possible to accumulate the bar code data large in capacity at the low price.

Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To achieve acquisition of AGC in a short time while avoiding the clipping of a large-level received I/Q signal by an A/D converter and avoiding restrictions on the number of quantization bits of the A/D converter even when a received signal is low in level. SOLUTION: The intensity of a received electric field is measured from the output of a BPF 2 to roughly adjust the gain of a variable gain amplifier 3. Then a control part 104 calculates deviation from a desirable signal amplitude value on the basis of an A/D-converted digitized receive I/Q signal output 16 and on the basis of its information, the gain of the variable gain amplifier 3 is finely adjusted again, thereby speedily converging the AGC operation through those two stages of the operation. Consequently, the preamble length for the AGC in a radio burst can be shortened, so the efficiency of a radio resource can be improved.
