Patent JP-H047619-A (JP)
Title: Bus control circuit
Inventor: HAYASHI NOBUO
IPC: G06F3/00
Filed: 1990-04-25
Abstract: PURPOSE:To reduce the power consumption of an integrated circuit by providing a first and a second inverters to make a first and a second transistors (TR) conductive respectively when bus potential reaches each threshold voltage, and making the threshold voltage of the first inverter and the threshold voltage of the second inverter different from each other. CONSTITUTION:Each gate of the TRs PM1 and NM1 is connected to a pre- charge signal circuit to output a pre-charge signal. Besides, a bus 2 is connected to the gate of the TR PM2 through the inverter IVP and connected to the gate of the TR NM2 through the inverter IVN. In this case, the threshold voltage of the inverter IVP is selected so as to be higher than the threshold voltage of the inverter IVN. Accordingly, immediately after the bus potential begins to change, a through current is interrupted, and the period during which the through current flows is shortened. Thus, the power consumption due to the through current can be reduced, and the bus potential can be inverted at high speed.

Title: Amplifying circuit
Inventor: KATOU HARUHIKO
IPC: H03F3/38
Filed: 1981-07-15
Abstract: PURPOSE:To synthesize outputs of a number of amplifiers efficiently by dividing a carrier, modulated in digital values, with time, and amplifying them reseptively. CONSTITUTION:An input signal from an input terminal 1 is a modulated wave obtained by modulating a carrier in digital values. A clock component is extracted from the input signal by a clock extracting circuit 8 and supplied to a control circuit 7. On the basis of the clock component, the control circuit 7 generates a switching control signal and sends it to an input switching circuit 6 and an output switching circuit 10. Therefore, the input signal from the input terminal 1 is divided with time by the switching circuit 6 and supplied as burstlike signals to unit amplifiers 9 and 9' which perform pulse operation by turns. Outputs of those amplifiers 9 and 9' are synthesized by the switching circuit 10. consequently, phase matching is unnecessary and outputs of a number of amplifiers are synthesized efficiently.

Inventor: MORIKAWA TOSHIYA
IPC: F04C2/10
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce the leakage of fluid as low as possible by arranged a seal member in a side clearance and also reduce a loss torque by the seal member by especially increasing a delivery efficiency at the delivery of fluid at a high pressure. SOLUTION: A device is structured so that an arc-shaped groove part 80 is formed between a center hole 701 and a delivery port 61 on a surface where a side plate part 71 is opposed to an inner rotor 52, and a seal member 81 is arranged in the groove part 80. Also the flange-shaped part 81a around the most outer periphery of the seal member 81 is apart from the inner rotor 52 in the initial state when brake fluid does not flow-in (a), and expanded from the initial state by a pressure of the brake fluid flowing in from a delivery port 61 side so as to fit it closely to the inner rotor 52 (b).  Because the construction is of the self close type in which a closing action is increased only at the delivery of high pressure causing a brake fluid leakage problem, a resistance against the rotating motion of the inner rotor 52 is reduced in those cases other than at the delivery of high pressure.

Title: Working method of surface of solid
Inventor: ONO TETSUO
IPC: H01L21/3065
Filed: 1993-05-12
Abstract: PURPOSE:To make an etched surface flat at the level of an atomic layer by using low-velocity polyvalent ions as a means to remove the adsorbed layer of halogens or the like formed on the surface of a semiconductor. CONSTITUTION:When a substance B of strong electronegativity such as a halogen is adsorbed to the clean surface of a solid A, a bonding hand 101 on the surface becomes relatively weak. At this time, when polyvalent ions C come near the surface, electrons are pulled out from the surface because their force to pull out the electrons is strong. As a result, the bonding hand 101 which is relatively weak is cut, the A/B are desorbed from the surface, and the surface of the solid A is etched by one atomic layer. When the kinetic energy of the ions C is set at a value at which the surface of the solid A is not sputtered, the chemical reaction of the surface is promoted by ionization energy with which the ions C are endowed, mechanical damage is not caused at all, and the surface of the solid after an etching operation becomes flat at the level of an atomic layer. Thereby, the mechanical damage of the surface ca be reduced.

Title: Method for detecting nitriding degree of steel part
Inventor: UCHIUMI YASUO
IPC: C21D1/55
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To detect a nitriding degree from a surface of a steel part simply, by obtaining a hardness whereby an amount of nitrogen at a predetermined heating temperature becomes zero, setting the hardness as a detection hardness, and obtaining a depth from the surface where the detection hardness is achieved after the steel part to be detected is heated at a predetermined heating temperature and cooled. SOLUTION: A bearing part processed through carbonitriding hardening and tempering is heated at a heating temperature 500 deg.C for one hour and returned to a room temperature. A detection hardness is set to be Hv500. A hardness of the bearing part through the process is measured while a surface is ground. A depth position where the detection hardness is achieved is obtained from a grind margin at a time point when the measured hardness becomes Hv500. A nitriding degree can thus be detected simply. The nitriding degree is identified by the above detection method, and a rolling bearing is manufactured by setting at least one of an inner and outer rings and a rolling element to have the nitriding degree of 1-6% an average diameter of the rolling element. A carbonitrided layer can be formed to a depth of 1-6% the average diameter of the rolling element if a nitriding degree is set.

Title: Vehicle obstruction detector
Inventor: CHIAOHON CHIYAN

Abstract: PURPOSE: To accurately discriminate a dangerous obstruction from an undangerous obstruction by comparing the difference between the relative speed, obtained from transmit-receive signals of a frequency modulated continuous wave signal and a continuous wave signal, with the predetermined threshold value. CONSTITUTION: In response to control signals 51, 52 from a digital processor 49, a modulator 47 with multiple functions outputs (60) constant DC voltage or linear lamp voltage, and continuous wave(CW) or frequency modulated continuous wave(FM-CW) radar signals are outputted (61) from a voltage controlled oscillator(VCO) 45. A mixer 44 inputs part of these radar transmit signals and a radar reflection signal received by a receiving antenna 42 and generates an IF signal which is amplified-filtered (46), A/D-converted (48) and sent to the processor 49.  The processor 49 determines distance from an obstruction and relative speed on the basis of these signals and compares the difference of the relative speed determined by FM-CW and CW with the predetermined threshold value, and judges the obstruction to be dangerous at the time of exceeding the threshold value and to be undangerous at the time of not exceeding the threshold value.

Abstract: PURPOSE:To eliminate interference signals by detecting the correlative amount from the difference between a regenerated pilot signal and angular-frequency-variation removing signal obtained by receiving the composite signal wave of three pilot signals correlative in amplitude, phase and frequency. CONSTITUTION:Respective pilot signals correlative in amplitude, phase and frequency obtained from outputs 131...133 of pilot signal generating circuit 101 are applied as carriers to modulators 160...162 and sent out via signal synthesizer circuit 104.

On the other hand, signals received from terminals 134 and 135, after its angular-frequency variation is removed, are supplied to circuit 107, where they are subtracted by signals from terminals 136 and 137 to make detection 190 of the correlative amount, thereby controlling circuit 104 by its output. Consequently, it is made possible to eliminate interference signals generated between the transmitting terminal and repeating terminal, and repeating terminal and receiving terminal.
