Patent JP-S63146530-A (JP)
Title: Time division multiplexer
Inventor: HIRAYAMA KOJI
IPC: H04J3/00
Filed: 1986-12-09
Abstract: PURPOSE:To eliminate the need for an elastic memory and a peripheral control circuit by comparing phases of a write signal and a readout signal for a coded signal in a buffer circuit and controlling the phase of the write signal so as to cause a prescribed phase difference between both the signals. CONSTITUTION:A coded signal written synchronously with a write signal S2 is read by a buffer circuit 3 synchronously with a read signal S4 and sent to a data bus 4. A phase comparator 8 compares phases of the write signal S2 and the read signal S4 and when the phase difference of both the signals is smaller than a preset value, a correction signal S5 is outputted to a signal generating circuit 1 to control the phase of the write signal S2 so that the phase difference between the write signal S2 and the read signal S4 keeps a prescribed value. The coincidence between the write timing and read timing of the coded signal in the buffer circuit 3 is evaded without employing an elastic memory for the buffer circuit 3 by using the phase control of the write signal S2 at the phase comparator 8.

Filed: 1985-12-26
Abstract: PURPOSE:To flatten a silicon oxide film by a method wherein an organic coating film is formed on a silicon oxide film with an uneven surface to be simultaneously etched at the specific rate using mixed gas of fluorine base compound and oxygen. CONSTITUTION:An interconnection pattern 2 is formed on a semiconductor substrate 1 and then a silicon oxide film 3 with an uneven surface is formed on the pattern 2. Furthermore, an organic coating film 5 with film thickness exceeding the unevenness step difference is formed on the surface of film 3. Next, the film 3 can be flattened by simultaneously etching the films 3 and 5 at the specific rate of 1.6/1-2.0/1 using mixed gas plasma of fluorine base compound and oxygen. Besides, the processing time can be cut down by etching the films 3 and 5 using oxygen gas plasma until the projecting part of film 3 begins to be exposed and later the mixed gas plasma of fluorine base compound and oxygen. Through these procedures, the film thickness of a conductor layer can be made even.

Abstract: PURPOSE:To obtain a uniformly printed face and lengthen a screen in life by a method wherein a squeegee is made to perform a smooth and non-oscillating squeegeeing. CONSTITUTION:A resist or a symbol is printed or coated on a printed wiring substrate through a screen printing. The base of a squeegee 2 is fixed to a supporting body which is a kind of a jig and made of metal or the like.

The squeegee 2 is made to shift continuously on a rugged face of the substrate touching steps formed through a circuit etching in a point contacting state. By these processes, a smooth and non-oscillating squeegeeing can be performed with a squeegee and a printed face is prevented from being irregular density. SO that, a screen can be made to be longer than the usual in a life span.

Abstract: PURPOSE:To improve a two-frequency shared helical antenna by fitting an output terminal at the lower end of a helical antenna element, inserting a conductor through an insulator to an upper end part, changing the insertion depth dimension of the conductor and adjusting a resonance frequency. CONSTITUTION:The lower end of a helical antenna element 8 is fitted at an output terminal 5, and a conductor 10 is inserted through an insulator 9 to the upper end part of the element 8. When a part 8a to insert the conductor 10 is a high frequency Fh, it is resonated in parallel to the conductor 10, impedance is significantly increased, and the part can be ignored. Together with this, a part 8b where the conductor 10 of the element 8 is not inserted is serially resonated, and at the time of a low frequency F1, an inserting part 8a of the conductor 10 of the element 8 becomes an inductive inductance. This and a conductor non-inserting part 8b becomes integral and are serially resonated. Then, a two-frequency shared helical antenna is obtained in which the two- frequency shared helical antenna structure is easy, the adjustment is easy and the cost is low priced.

IPC: H04N19/134
Filed: 1992-11-02
Abstract: PURPOSE:To enable satisfactory vector quantization by adding update processing based on the increase and extinguishment of representative vectors to the successive update processing of representative vectors. CONSTITUTION:Input vectors are sent to a quantizing part 1 and a learning data preparing part 4, sampled for every fixed cycle by the preparing part 4 and sent to a distortion calculating part 5 as learning data. The calculating part 5 calculates the distortion of the representative vectors in a code book 3 and the inputted learning data, and the representative vector with minimum distortion is defined as amost adjacent vector. The ID of this vector is sent to the part 1 and a correcting part 6. Thus, the part 1 outputs quantized data. On the other hand, the part 6 counts the number of accumulated input vectors and when this number is coincident with a certain value, frequency for each representative vector is normalized by referring to a frequency table 7. At the time of non-coincidence, '1' is added to the frequency corresponding to the ID, and the representative vector corresponding to the most adjacent vector is corrected/updated and stored in the book 3.
