Patent JP-H0324820-A (JP)
Title: Output circuit
Inventor: HAGURA TSUKASA
IPC: G11C11/409
Filed: 1989-06-21
Abstract: PURPOSE:To suppress ringing to shorten an access time by generating a one-shot pulse before the fall of an output voltage to 0V or lower at the time of outputting the low level, and turning on an n-channel transistor TR having a low threshold voltage for a moment to apply the voltage from VCC to the output. CONSTITUTION:When a signal OEM goes to the high level, a node (c) goes to the low level and a node (d) goes to the high level, and a TR 9 is turned off and a TR 10 is turned on, and the low level is outputted to an output Dout. Since the signal OEM goes to the high level, a node N1 goes to the low level, and a node N2 goes to the high level after a short delay. Both of nodes N1 and N2 go to the low level for a moment, and this low level is outputted to a NOR gate 16 to generate the one-shot pulse, which goes to the high level for a moment, in the output of the NOR gate 16. A TH 19 is turned on for the moment, when the pulse of a node N3 goes to the high level, to supply the voltage to the output Dout, and the negative voltage of the output Dout is cancelled. Thus, ringing is eliminated.

CONSTITUTION:The cement composition consists of a cement admixture consisting essentially of a calcium aluminosilicate glass contg. the oxide of a trivalent metal other than aluminum and gypsum and cement. When this admixture is used, the early strength and long-term strength are increased, and the cement is hardly crazed. Further, the admixture is used in the same way as before, and the admixture is widely applicable for the secondary product such as prefabricated product, road, building, tunnel, etc., requiring a desired strength in a short time, or as the road repairing, grouting and stopwater materials.
Patent JP-H0323712-A (JP)
Title: Semiconductor integrated circuit
Inventor: OZAKI HIDEYUKI
IPC: H03K19/0185
Filed: 1989-06-20
Abstract: PURPOSE:To suppress ringing and also, to obtain VOH and VOL margins by inserting a resistor with a comparatively large resistance value between an output transistor and an output terminal, and providing a switching element to bias the resistor with certain delay time. CONSTITUTION:The resistor with the comparatively large resistance value is inserted between the output transistors TR1, TR2 and the output terminal, and an N-channel MOS transistor TR3 is provided in parallel with the resistor. And the output of a NOR gate 8 setting a node A and a node B as two input is connected to the gate of the N-channel MOS transistor TR3 connected in parallel with the resistor via delay circuits 5-7. Thereby, the output of the transistor TR1 or TR2 goes to 'H' via the resistor R when it is energized, however, at this time, the rise of the output is moderated since it passes through the resistor R, thereby, the ringing is suppressed. When a node C goes to 'H' with certain delay, the transistor TR3 is energized, and the resistor R is bypassed after a time t3, therefore, a final level of 'L' goes to almost 0V.

Filed: 1993-06-29
Abstract: PURPOSE:To provide high sensitivity and to reduce the deterioration of a charging characteristic even in the case of repeated use, by using the specific tris-azo pigment for a photosensitive layer. CONSTITUTION:A photosensitive layer is formed on an aluminum hydroxyoxide coating on a conductive supporting body surface, and contains a tris-azo pigment, which has a following X-ray diffraction pattern and is expressed by the formula. The x-ray diffraction pattern has diffraction peaks at 2theta=7.0+ or -0.5 deg., 2theta=12.0+ or -1.0 deg. in a powder X-ray diffraction pattern by a Cu-Kalpha line, and a ratio X of diffraction intensity for the peak at 2theta=7.0+ or -0.5 deg. to diffraction intensity for a background is set to X=(P-B)/B<=2.0. P represents X-ray intensity in the peak position 2theta=7.0+ or -0.5 deg., while B represents X-ray intensity for a peak position of a line, which binds troughs on both sides, in the same peak position. In other words, when a certain peak in the X-ray diffraction pattern is noticed, a tris-azo pigment, in which a ratio between intensity of the peak and intensity of the background takes a certain value or more, is applicable.

Abstract: PURPOSE:To reduce the extent of bearing loss by installing an automatic variable oil-level circuit, changing a supply oil quantity according to rotational frequency, and simultaneously making a proper quantity of lubricating oil and air so as to be mixed together after selecting a mixing valve. CONSTITUTION:When spindle speed is 8,000r.p.m., by way of example, a numerical control system 10 controls a timer 16, through which a proper quantity of lubricating oil is fed out of a pneumatically-driven piston pump unit 1. Simultaneously with this, solenoid valves 15, 18 and 38 are selected to each of II, IV and VI positions whereby the side of a mixing valve unit 24 is interconnected to a bearing. Therefore lubricating oil is mixed with air regulated to a flow rate commensurate to the said speed 8,000r.p.m. by a throttle 28 and then fed to the bearing. Next, when the spindle speed is selected to 13,000r.p.m., a cycle of the timer 16 is changed, the lubricating oil increases in quantity and thus it comes to the proper quantity. At the same time, these solenoid valves 15, 18 and 38 are changed to each of I, III, V positions, the side of a mixing valve 22 is interconnected to the spindle, so that it is mixed with air regulated to a flow rate commensurate to the said speed 13,000r.p.m. by a throttle 27 and thus the lubricating oil is supplied.

Filed: 1980-11-11
Abstract: PURPOSE:To realize a normal operation of a phase control circuit regardless of a high level of power supply voltage, by adding a diode for suppression of voltage to a switching element for trigger of a thyristor. CONSTITUTION:A resistance R6 and a phototransistor (TR) Q2 are connected between the gate and the anode of a thyristor CR; and diodes D2 and D3 for suppression of voltage are connected between the collector of the TRQ2 and the cathode of the thyristor CR. The TRQ2 does not conduct in case no signal is applied between input terminals 3 and 4, and accordingly, the CR is not turned on. While the TRQ2 conducts when the signal is applied between the terminals 3 and 4, and accordingly, the CR is turned on. Thus a Triac BCR is triggered to supply the electric power to a load 5.

Title: Logical cell arrangement
Inventor: MUROFUSHI MASAKO
IPC: H01L21/822
Filed: 1991-07-01
Abstract: PURPOSE:To obtain high quality arrangement result and floor plan result which conforms to the requested signal transfer time and satisfies a plurality of objects. CONSTITUTION:A wiring length of each net is forecasted on the basis of the largest rectangular consisting of cells connected to such net. It is evaluated in what degree fine movement of cell or cell group gives influence on signal transfer time of net or on signal transfer time of path (steps S2 to S4). A candidate cell for movement is selected from the probability by obtaining easiness of selection of the candidate cell for movement which is effective to shorten the signal transfer time (steps S5, S6). The moving position of cell is determined and the cell is fine-moved to this position (step S7). Therefore, a signal transfer time of path can be shortened and it can be combined easily with the improvement for the other object on the occasion of automatic arrangement.
