Title: Cassette tape deck device
Inventor: ISHIBASHI KAZUAKI
IPC: G11B15/087
Filed: 1993-12-21
Abstract: PURPOSE:To prevent the malfanction of rewinding a tape at a silent interval of music at the time of reproducing after winding by a repeating operation is finished. CONSTITUTION:After rewinding of music in a cassette tape to be repeated is started, the control part 10 of a microcomputer 9 controls a mechanism part 1 via a driver 2 based on an instruction given from an operation part 8 and rewinding of the music is started. When the rewinding continues and time of silent part thereof is a threshold value T1 or higher, the control part 10 identifies intermusic and reproducing of the music to be repeated is started. Then, after the reproducing of the music to be repeated in the rewound tape is started, the control part 10 identifies finishing of the nonsound part in the music to be repeated when a value obtained by counting the number of silent parts corresponding to recorded time by a silent timer 11 is 0, and when an instruction for repeating is given during reproducing, rewinding by repeating in intermusic is started. Thus, erroneous identification of the silent part in the music as intermusic and starting of rewinding again are prevented.

Title: Quantization noise reduction device
Inventor: NOGUCHI TADASHI
IPC: H03H17/02
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a quantization noise reduction device by which the effect of quantization noise is reduce from even a quantized value made to an analog signal whose amplitude level is relatively smaller than a quantization width. SOLUTION: In the case of reducing quantization noise by converting a sample data string composed of a prescribed word-bit length M into a string with a word bit length N higher than the M, output signals of bit length conversion means 21-24 are divided into plural band components, each level of an input signal obtained for each divided band is compared with each reference level 71-74, and when the signal level is smaller than the reference level, a control signal is outputted to attenuate a corresponding band component, the band components are synthesized 4 again and the result is outputted as a sample data string with a bit length N.  Waveform distortion for a very small signal is reduced by bit length extension and a gain at a frequency band whose quantization noise is dominant is decreased, then a signal waveform with more fidelity with an original signal is reproduced even from a signal reproduction device accompanied with digital conversion.

Title: Fuel injection control device for internal combustion engine
Inventor: ISOBE TAIJI
IPC: F02D41/06
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To attain position combustion from first injection fuel at the time of start-up. SOLUTION: An air-fuel ratio range where a mixture in a cylinder is combustible is estimated on the basis of cooling water temperature (step 200). A total quantity of fuel having leaked from a fuel injection valve during stop of an engine is estimated (step 300), and a leakage fuel intake quantity taken into one cylinder out of leakage fuel is estimated (step 400). Taking account of the leakage fuel intake quantity, a start-up time fuel injection quantity is computed so that an air-fuel ratio of an intake mixture at the time of start-up is within a combustible range at the time of start-up (step 500). Fuel is injected at this start-up time fuel injection quantity synchronously with an intake stroke of each cylinder from first fuel injection.  A combustion state of fuel in the first injection is judged, and on the basis of the judged result, a correction value to be reflected to compute a fuel injection quantity at the time of the following start-up is learned (step 600). Positive combustion can therefore be attained from a first injection fuel at the time of start-up.

Title: Ferroelectric liquid crystal element
Inventor: YOSHIDA AKIO
IPC: G02F1/1337
Filed: 1991-12-05
Abstract: PURPOSE:To improve the stability to the mechanical stress of a liquid crystal by setting the diffraction peak area of the layer structure of the liquid crystal sealed between a pair of electrode substrates smaller than in the case of orientation with a specific orienting material. CONSTITUTION:The diffraction peak area of the layer structure per unit gap between the substrates 11 and 19 of the ferroelectric liquid crystal 15 sealed between a pair of the electrode substrates is set at <=70% of the case of orientation by the orienting material expressed by formula. More preferably, the ferroelectric liquid crystal 15 having a smectic A phase is used in a temp. lowering process and the liquid crystal 15 is pressed in the temp. lowering process, by which the layer structure in the smectic A phase is distorted. Thus, the diffraction intensity of the unit cell gap of the X-ray diffraction based on the phase structure of the chiral smectic C phase existing on the low-temp. side is decreased to the intensity lower than the diffraction intensity of the cell oriented by the orienting material expressed by the formula. Since the formation of the layer is rough in such a case, the load resistance to a specified load is improved and further, the impact resistance is improved as well.

Title: Plastic-sealing apparatus improved for integrated circuit lead frame and method therefor
IPC: H01L21/56
Filed: 1992-12-28
Abstract: PURPOSE: To disclose an apparatus for sealing an integrated circuit lead frame with a resin. CONSTITUTION: This apparatus comprises a basin 16 of a plastics 25 melting with a lead frame 20, a runner 18 and upper and lower dies 12, 14 which define a package region with a flow pocket 21 for equalizing the flow of the plastics 25 in the package region. The integrated circuit lead frame has flow holes to allow the molten plastics to flow from the runner 16 to the flow pocket 21 and lower space of the package region. The runner is to flow the molten plastics 25 directly to an upper space of the package region. Thus the plastics 25 is more uniformly injected into the upper and lower package spaces, and the cavity, at the same time. This reduces the possibility of causing air pockets, wire drifting voids or other defects in a final plastic package.
