Title: Device for controlling air-fuel ratio of carburetor
Inventor: TANAKA HIROFUMI
IPC: F02M7/24
Filed: 1989-01-13
Abstract: PURPOSE:To keep the air/fuel ratio of a mixture at a proper value and prevent engine stall by opening/closing a flow control valve for regulating air-fuel ratio at a low speed based on the output of an oxygen sensor, at the time of switchover from an air/fuel ratio control at the time of opening a throttle valve to an idle feedback control. CONSTITUTION:A flow control valve 8 regulates the air/fuel ratio of a mixture by opening/closing the air bleed passage 7 of a carburetor 1, while being controlled so as to carry out opening/closing at a low speed when a throttle valve 4 is in an idling position based on the output of an oxygen sensor 15 for detecting oxygen density in exhaust gas, by an idle feedback control means 20. Also, when the throttle valve 4 is returned to the idling position, switchover is immediately carried out by a control switchover means 21 from the control at the time of opening the throttle valve to the control by the idle feedback control means 20, while making the average value of the idle control position of the flow control valve 8 a control starting position.

Title: Gas oil fuel containing liquefied petroleum gas dissolved therein
Inventor: YUKIMORI TAKAO
IPC: C10L1/16
Filed: 1985-01-19
Abstract: PURPOSE:To provide fuel which does not emit black smoke in exhaust gas and to increase combustion efficiency and the output of engines, by dissolving liquefied petroleum gas in gas oil in a closed pressure vessel and using the gas oil as fuel for diesel engine. CONSTITUTION:Liquefied petroleum gas (LPG) is dissolved in gas oil under its vapor pressure in a closed pressure vessel. The resulting gas oil contg. LPG dissolved therein is used as fuel for diesel engines. When this gas oil fuel is injected from a fuel injector into a combustion chamber, the LPG-contg. gas oil fuel is well dispersed as compared with gas oil, because it has a low viscosity. LPG has a low b.p. and is highly volatile as compared with gas oil, so that LPG is immediately gasified and diffused and the atomization of gas oil is promoted by the diffusion of LPG, whereby combustion efficiency and the output of engines can be improved.

Title: Device and method for testing airtightness of screw hole of semicylinder body
Inventor: MATSUMOTO YOSHITAKA
IPC: G01M3/12
Filed: 1990-01-16
Abstract: PURPOSE:To conduct a test wherein an in-use state is incarnated by covering the semicylinder body which is fitted to a slidable table with a body to be tested and pushing up the table while engaging an airtight lid threadably with the screw hole and pressing it with an elastic cap. CONSTITUTION:The body W to be tested is superposed on the semicylinder body 3 right below a clamping device 5 and the airtight lid 4 is engaged threadably with the screw hole H of the body to be tested. Then the table 2 is moved and a pressing-up device 8 pushes up the body W to be tested together with the table 2; and the elastic cap 6 which is moved down is crimped to the airtight lid 4 and while a vacuum device sucks air upward, a pressure air sending device 9 sends pressure air to between the body W to be tested and semicylinder body 3 in the airtight state from below to applying pressure to a gap. Consequently, if the airtightness of the threadable engagement state of the air tight lid 4 is deficient, an alarm buzzer sounds. It is therefore decided that the tested body W is normal unless the buzzer sounds for a preset time, and the decision result at the actual site is high in matchability.

Title: Tone signal detector
Inventor: SUGINO YUKIMASA
IPC: H04Q1/457
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To detect the presence of phase inversion by finding a phase change through an arithmetic operation and comparing the phase change with a prescribed value because a phase of a PCM signal is changed when there is a prescribed relationship between a sample number of the PCM signal and a period of a tone signal being a detection object and phase inversion takes place in the PCM signal. SOLUTION: A discrete Fourier transform DFT arithmetic section 11, once receiving a sample stream of PCM signals performs DFT arithmetic operation to the signal to find the PCM signals is a frequency region and provides outputs of the result, a real part R and an imaginary part Q to a phase calculation section 12. The phase calculation section 12 calculates a phase PH of the PCM signal by using an arithmetic equation relating to the polarity of the real part R and the imaginary part Q. A phase inversion discrimination section 13 calculates a change in the phase PH based on a difference between the current phase PH and the phase PH calculated for a preceding processing frame.  When a sampling number and a period of a tone signal have a prescribed relationship and no phase inversion takes place in the PCM signal, since the phase PH is constant, the phase difference is compared with a threshold. When the difference is higher than the threshold, it is discriminated that there is phase inversion.

Filed: 1991-01-29
Abstract: PURPOSE: To maintain a synchronous state for a long time by tracing a reference signal regardless of temperature, voltage and process fluctuations and therefore generating plural clock signals which synchronize with a reference clock. CONSTITUTION: A processor unit 12 which operates in response to clock signals that are given from a clock generator 14 generates various control signals which are sent to a control/controlled logic 18 via a multiple signal line bus 16.
