Title: Precharging system of semiconductor memory
Inventor: IIMA TAKEFUMI
IPC: G11C11/41
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous data writing by inputting a voltage in the near end side of the nearest word line from an output of a decoder circuit, outputting a signal for precharging only when any word line is not selected by the decoder circuit and then conducting the precharging to the data line through the switching operation depending on such output signal. SOLUTION: When any one of the word lines WL1 to WLn is selected by a decoder circuit 3, the decoder circuit 3 outputs the power supply voltage to the selected word line. From a NOR circuit 6, the ground potential is output almost in the same timing as the output of the power supply voltage from the decoder circuit 3 and the ground potential appears at the far end side of the data line WL0 after a delay of time Tp from the near end side. When the WL0 delay time Tp is set longer than the word line delay time Tw, overlap of the selecting operation of the word line can be prevented and power consumption can also be saved.

Filed: 1993-06-11
Abstract: PURPOSE:To give a time variation to the timbre of a musical sound with simple constitution by distributing a musical sound signal to plural systems, varying the level of one system with time, and passing the distributed signals through different filters, for every system, and then putting them together. CONSTITUTION:A multiplier 23 multiplies a waveform signal by an envelope signal and outputs the musical sound signal. The musical sound signal is inputted to two multipliers 24 and 25, and multiplied by a level control signal from a coefficient generator 26 respectively. The outputs of the multipliers 24 and 25 are inputted to two adders 27 and 28 respectively, and added and multiplexed with signals of other channels, so that the resulting signals are outputted to two filters. Thus, the generated musical sound signal, for example, is distributed to two systems and the level of one system is attenuated according to an exponential function; and this signal is passed through a high-pass filter and multiplexed with the signal which is already passed through a low-pass filter. The higher harmonic components attenuate with the time and the musical sound signal which varies in timbre is obtained.

Title: Catalytic cracking of heavy oil containing distillation residue
Inventor: USHIO MASARU
IPC: C10G11/18
Filed: 1979-12-21
Abstract: PURPOSE: To save a make-up catalyst, by withdrawing part of the catalyst contained in the unit, selecting the withdrawn catalyst by a high-gradient magnetic separator and recirculating only that portion of the catalyst which is not attracted by the magnet, in the fluidized catalytic cracking of heavy oil containing a distillation residue.  
     CONSTITUTION: In the fluidized catalytic cracking of heavy oil containing a distillation residue, part of the catalyst fluidized in the cracking unit is withdrawn and replaced with a fresh catalyst in order to prevent lowering of conversion due to deposition, on the catalyst, of metals contained in the oil, such as Ni and iron. During this process, the withdrawn catalyst is separated into a portion not attracted and a portion attracted by a high-gradient magnetic separator. The nonattracted portion which has still a high activity and selectivity is circulated to the cracking unit and reused. This saves a make-up catalyst, while preventing increase of coke and hydrogen in the product and decrease of conversion.

Filed: 1988-07-05
Abstract: PURPOSE:To reduce the weight of the deflector and decrease windage loss due to air resistance by dividing a rotary polygon mirror which is longitudinally wide into rotary polygon mirrors which are longitudinally narrow and connecting them by a connection part which is as large as or smaller than their inscribed circle. CONSTITUTION:This device is provided with the rotary polygon mirrors 3 which deflect plural light beams, the connection part 8 which is formed as large as or smaller than the inscribed circle of the rotary polygon mirrors 3 and connects those mirrors 3, and a driving motor 4 which drives and rotates the rotary polygon mirrors 3 and connection part 8. Consequently, the total weight of the rotary polygon mirrors 3 and connection part 8 is made smaller than that of the conventional rotary polygon mirror which is longitudinally wide. Further, the rotary polygon mirrors 3 rotate at a high speed, so when the all mirror surfaces form a polygon, the windage loss is large, but when the connection part 8 which does not scan any beam is sectioned circularly, the windage loss is reducible.

Title: Hybrid ic
Inventor: YOSHINO TAKEO
IPC: H01L23/467
Filed: 1993-06-14
Abstract: PURPOSE:To enhance the environmental resistance by making openings in the peripheral surface of a vent pipe projecting to the outside of a cover member thereby enhancing the heat dissipation efficiency in the forced air cooling. CONSTITUTION:Upon operation of a fan 3, cool air is blown directly to each hybrid IC 1. The cool air is also blown directly to the surface of a vent pipe 17 and thereby heat is also dissipated from the surface thereof. Furthermore, air flow generated in the vent pipe 17 dissipates heat from the inner surface thereof. In other words, since the vent pipe 17 is opened at first and second asymmetrical positions and the width of opening occupies 40-50% of the outer diameter of vent pipe 17, any one opening is opened entirely or partially toward the upstream side. Consequently, the air flows through the vent pipe 17 from the opening directing toward the upstream side and leaves the opposite opening. This structure realizes positive heat dissipation from the inner perpheral surface of the vent pipe 17.
