Title: Semiconductor integrated circuit device
Inventor: SATO KATSUYUKI
IPC: H03K5/133
Filed: 1987-02-27
Abstract: PURPOSE:To speed up a nibble mode or the like by setting the potential of a capacitor constituting a delay circuit to 'H' or 'L' by a control signal. CONSTITUTION:The inverse of a low address strobing signal (RAS), the inverse of a column address strobing signal (CAS) and the inverse of a write enabling signal (WE) are supplied from the external to a DRAM as control signals. Under these control signals, a timing signal phipc is supplied from a timing control circuit TC to a precharging circuit PC for a memory array M-ARY. The circuit TC includes plural delay circuits having a function for selectively shortening a delay time by forcedly turning the capacitor potential to the 'H' or 'L' level. Consequently, the repeating operation of the nibble mode or the like in the DRAM can be speeded up.

Title: Cement composition
Inventor: INOUE TOSHIKATSU
IPC: C04B7/345
Filed: 1995-03-02
Abstract: PURPOSE: To obtain a cement composition excellent in fluidity, kneadability and strength developability, and suppressed in temperature rise during cure with suppressed heat generation during hydration. CONSTITUTION: This cement composition comprises a total of 100 pts.wt. of 50-92 pts.wt. of high-belite-based Portland clement, 5-25 pts.wt. of silica fume and 3-25 pts.wt. of limestone fine powder. The high-belite-based Portland cement stands reduced to a minimum in the amounts of both alite and aluminate constituting clinker mineral composition in the cement in order to reduce the heat of hydration to a minimum so as to prevent the temperature rise of the resultant concrete structural body and also stands sufficiently increased in the amount of belite excellent in long-term strength developability. Owing to using the high-belite-based Portland cement, heat generation due to cement hydration can be suppressed to low levels; therefore, in the resultant thick-walled high- strength concrete structural body, temperature rise is small, crack development prevented, and strength developability improved.

Title: Chroma signal processing circuit
Inventor: YOSHIDA MASAYASU
IPC: H04N9/89
Filed: 1992-02-28
Abstract: PURPOSE:To reduce color noise with simple circuit constitution by adding the outputs of a smoothing circuit and a limitter with an adder and controlling a reference signal oscillator with the output signal of the adder. CONSTITUTION:A reference oscillation signal is outputted from the reference signal oscillator 101, and the signal and a color auxiliary carrier signal inputted from an outside are inputted to a phase comparator 102. Phases are compared in the comparator 102. A phase error signal is outputted and amplified in an amplifier circuit 104. The amplified signal is arranged to a prescribed amplitude by a limitter 105 and smoothed with the smoothing circuit 103 at previously decided timing. The adder 106 adds the output of the limitter 105 with the output of the smoothing circuit 103, and the oscillator 101 is controlled by the output signal. Then, the limitter 105 fetches only micro amplitude as a noise signal, and inputs only a high frequency to the circuit 104 through a high pass filter. Thus, phase is locked together with the color burst of a color auxiliary carrier. Thus, color noise can be reduced with the simple circuit constitution.

IPC: G01S15/10
Filed: 1983-03-15
Abstract: PURPOSE:To prevent malfunctioning due to an instantaneous ultrasonic noise by adding a delay circuit to a reflected signal outputted with a reflected wave from an object to be detected. CONSTITUTION:Output l of a memory circuit 13 is outputted to output circuits 17 and 18 through a delay circuit 19 having a delay time T. Outputs (o) and (p) of an output discrimination circuit 20 control the output circuits 17 and 18 judging an output (n) of a delay circuit 19 from the output l of the memory circuit 13 and an output (m) of a memory circuit 16 whether it exists within a time range of a gate circuit 7 or that of a gate circuit 8. In other words, a delay function is outputted only when a reflected wave from an object being detected exists continuously within the respective time ranges of the gate circuits 7 and 8 during the delay time T. With such an arrangement, malfunctioning due to an instantaneous ultrasonic noise can be prevented.
