Title: Timing controlling circuit
Inventor: MURAKAMI SHIYUUJI
IPC: H04L7/02
Filed: 1980-05-23
Abstract: PURPOSE:To reduce the space occupied by a delay element in a digital signal transmitting device, by securing a coincidence of phase between the data signal and the clock signal without using a delay element to the data signal. CONSTITUTION:The clock signal applied to a terminal 101 receives a change of phase by a phase shifter 102 to be delivered to a terminal 104. The output signal of the shifter 102 receives a time delay by a delay element 105 to be delivered to a terminal 107. This delayed clock signal receives a comparison of phase with the clock signal of the terminal 101 through a phase comparator 103, and the phase error signal is applied to a low pass filter 106 to be eliminated for the noise component. Such clock signal is then applied to the phase shift extent control signal terminal of the shifter 102. Thus the phase shift extent is controlled toward the direction where the above-mentioned phase error signal is reduced.

Filed: 1994-04-07
Abstract: PURPOSE:To realize excellent stripping properties and electrode pattern forming properties by forming an electrode pattern directly onto a multilayer stripping layer, comprising a first layer dedicated for stripping and a second layer dedicated for formation of electrode pattern formed on a base film, and then thermally transferring the electrode pattern onto a ceramic green sheet. CONSTITUTION:A layer 8 dedicated for stripping and a layer 9 dedicated for formation of electrode pattern are formed on one side of a base film 2 and an electrode pattern 3 is formed thereon. The electrode pattern 3 is superposed on a ceramic green sheet and hot pressed thus transferring the electrode pattern 3 thermally onto the ceramic green sheet. This method produces an electrode pattern excellent in stripping properties, thermal transfer properties and patterning properties. Since the pattern is prevented from being blurred, smeared or expelled, mass productivity and reliability can be enhanced.

Title: Treatment of dust and sludge
Inventor: HARADA AKIHISA
IPC: C22B1/14
Filed: 1986-03-26
Abstract: PURPOSE:To effectively treat dust and sludge in the exhaust gas from a vertical furnace at a low cost, by recovering medium fine powder from the high-temp. exhaust gas from which coarse grain content is previously removed, by precipitating fine powder into slimy state, and by mixing the medium fine powder and the slimy fine powder to undergo briquetting. CONSTITUTION:After the coarse grain content is recovered by means of a dust catcher 17 and a cyclone 18 from the high-temp. exhaust gas discharged from the vertical furnace 16 for Fe-Mn manufacture, the medium fine powder is recovered by means of a multicyclone 19. Subsequently, the exhaust gas is fed into a venturi 24, where fine dust and sludge are caught by means of showery water. The above fine dust and sludge are precipitated in a thickener 25 and dehydrated by means of an Oliver filter 26 to be formed into slimy dust and sludge 27. The medium fine powder and the slimy dust and sludge 27 obtained in this manner are charged together with cement 28 into a pelletizer 29 in the prescribed percentages to undergo briquetting with the addition of the coarse grain content, if necessary. In this way, dust and sludge in the exhaust gas can be briquetted at a low cost and recycled as raw material for iron and steel manufacture.

Title: Flip-chip having gourd-shaped protruding electrode
Inventor: KANEDA KOJI
IPC: H01L21/60
Filed: 1988-03-25
Abstract: PURPOSE:To enhance the reliability of a bump by a method wherein the bump is shaped to be an oval as a whole and a groove-like part is formed in its central part to be, e.g., gourd-shaped. CONSTITUTION:A groove-like part 3 is formed at a bump 2 toward the inside in the central part of an oval-shaped bump; the bump 2 is formed to be gourd- shaped as a whole. Its length in the longitudinal direction is the same as that by a conventional system; its length in the transverse direction is short as compared with that by the conventional system. When a flip-chip 1 is to be mounted on an Si wiring substrate 4, an angle theta formed by the surface of the chip 1 and an end face of the bump 2 becomes larger than that by the conventional system. Accordingly, a shearing stress in the transverse direction is strengthened. By this setup, the reliability of the bump 2 can be enhanced.

Abstract: PURPOSE:To synchronize a video data with an audio data by providing a means stopping the operation of an audio decoder till the write of a reproduction video data is finished when the collation of frame numbers indicates coincidence to the reproduction device. CONSTITUTION:A comparator circuit 27 of a video sequencer compares a frame number a during write or already written outputted from a selector 25 with a frame number beta outputted from a frame counter 26.

Title: Character processor
Inventor: KISHINO MARIKO
IPC: G06F17/21
Filed: 1990-03-19
Abstract: PURPOSE:To improve the availability of a dictionary memory by storing the swing information on the word description into the dictionary memory and converting the words, etc., by reference to the variability information stored in the memory. CONSTITUTION:A dictionary stores previously the read element description, the parts of speech, a variability flag, the frequency, and a standard flag. An input read train is searched out of the dictionary and the description corresponding to the read string is taken out. Then plural descriptions are evolved by reference to the variability information on the description owned by the read string and based on the taken-out description. These evolved descriptions are sorted in the order of frequencies. When the standard conversion is designated, the standard description is first converted and outputted onto a text buffer and then displayed on a CRT. Thus the memory availability is improved and the cost and the processing time can be reduced.

IPC: H02P8/14
Filed: 1984-04-10
Abstract: PURPOSE:To prevent a torque characteristic from decreasing by effectively setting a pause zone by a CR time constant, and sharply forming a rise of a drive signal, thereby preventing the abnormal operation. CONSTITUTION:A CMOS type is used for AND circuits AND1-AND4 which form a pause zone generator 7. Thus, the input impedance of the AND circuits is very high, and the threshold value level is decided to almost one point. Accordingly, the pause zone can be effectively set by time constants of the time constant circuit of resistors R1, R2 and a capacitor Ca and the time constant circuit of resistors R3, R4 and a capacitor Cb, and the waveform having an abrupt rise is obtained. Since only two capacitors are sufficient, the circuit configuration can be simplified.
