Title: Pwm signal output circuit
Inventor: NURITANI KOUZOU
IPC: H03F3/217
Filed: 1987-01-09
Abstract: PURPOSE:To decrease thermal resistance noise in a PWM output circuit by connecting a PWM signal to an integrator imaginary ground point comprising an operational amplifier via n-set of PWM output logic circuits and current resistors. CONSTITUTION:A PWM modulation circuit 1 outputs a signal having a pulse width in response to a digital input, an output is given by a binary value (1 bit) of high level '1' and low level '0', and the PWM output logic circuit 7 has a current capacity supplying a current to a current summing resistor 8. Then the PWM signal is connected to the integrator imaginary ground point via the n-set of PWM output logic circuits 7 and resistors 8 to extract the PWM output demodulation signal amplified by the current summation. Since the signal is amplified by current summation in this way, the thermal resistance noise is eliminated by a low pass filter and the noise in the input resistor is decreased to 1/n.

Title: Measuring method of grain size distribution by light transmission type
Inventor: KURAMOTO SHINICHI
IPC: G01N15/04
Filed: 1982-01-13
Abstract: PURPOSE:To make the measurement of a wide range of grain size distribution possible with a slight error in a short time, by controlling speeds in such a way that the number of revolutions of a cell for measuring light transmittance decreases gradually with the time since the start of the rotation thereof as a function. CONSTITUTION:A cell 1 contg. suspended liquid is set in a centrifuge 2, and while the cell is rotated in an arrow direction, the light transmitted therethrough is detected with a photosensor 3 consisting of a light emitting element and a photodetector which are disposed on the front and rear of the cell 1 so as to face each other. Grain size distribution is calculated in accordance with known prescribed equations. When the centrifuge 2 is rotated at a specified speed, the grain sizes to be obtained are inversely proportional to the 1/2 square of the data measuring time and the measurement takes time, but if the rotating speed is increased in porportion to the 1/2 square of the time since the start of rotation, the grain sizes are inversely proportional to the time, whereby the measurement of a higher range of grain size distributions in a shorter time is made possible. Since initial jitters are eliminated, errors are reduced.

Filed: 1980-01-18
Abstract: PURPOSE: To prevent such troubles as leakage of fuel from a carburetor, sucking-out of oil, etc. by a method wherein a supercharger is provided separately from the intake system of the carburetor, and the supply of a fuel-air mixture and the pressure charging can be performed independently by separate intake valves.  
     CONSTITUTION: At the time of engine operation, exhaust gas is fed from an exhaust valve 8 to an exhaust-gas turbine 16 of the supercharger 13 through an exhaust pipe 18 and rotates the turbine 16, thereby driving a blowing pump 17. Accordingly, air is sucked in from an air cleaner 10 and pressurized, and a supercharge of air is fed to a combustion chamber 2 through a supercharging pipe 14 and the intake valve 5. On the other hand, since the other intake valve 4 is also opened during the intake stroke, the mixture formed in the carburetor 11 is fed into the combustion chamber 2. Accordingly, it is possible to eliminate such inconveniences as the leakage of fuel from the carburetor 11 and the sucking-out of oil, which are encountered in cases where the supercharger 13 is placed on the upstream or downstream side of the carburetor 11.

Inventor: OBATA SHIGEO
IPC: H02K29/14
Filed: 1994-01-20
Abstract: PURPOSE:To suppress the superposition of noise to FG signals by arranging pairs of FG lead element wires. CONSTITUTION:Since an FG element wire 2 is interlinked with the main magnetic poles 8 of a rotor magnet 5, while the rotor magnet 5 rotates once, the number of magnetized magnetic poles of the main electrode 8 corresponds to it, and noise for eight cycles are superposed. But, since m pairs (m=2, 3...) of FG lead wires 4 are connected, with their phases changed 360 deg. (m+1) at a time, to the FG lead element wire 2, the noise superposed on the FG lead element wire 2 occurs also in the other lead element wire 4, with its phase changed. As a result, the noise superposed on the FE lead element wire 4 is added to the noise generated in other FG lead element wire 4 and those are averaged, thus those can be suppressed to nearly zero.

Abstract: PURPOSE:To offer a programmable controller allowing a worker to quickly grasp the cause of abnormal operation of an actuator or the like to be controlled. CONSTITUTION:A graphic data memory 12 stores an arrangement drawing and a program diagram formed by a graphic programmer 17. In the case of inputting a simultaneously display request for simultaneously displaying the arrangement drawing and the program diagram to the programmer 17, a control module 11 allows the programmer 17 to simultaneously display both the arrangement drawing and program diagram stored in the memory 12. Consequently a failed limit switch causing the generation of abnormal operation can quickly be detected without executing complex checking work based upon convensional I/O allocating diagram and wiring diagram.

Title: Anticorrosive process for piping
Inventor: TAWARA HISATO
IPC: F16L58/02
Filed: 1978-01-23
Abstract: PURPOSE: To prevent the corrosion in piping very efficiently without using a specially complicated device by pushing air, nitrogen, or other pressurized gases constantly into the piping to prevent the entering of corrosive gases.  
     CONSTITUTION: Into an emergency spray piping 14 arranged in an entrance duct part 1 of a combustion apparatus, the air or a gas is pushed or introduced without using a specially complicated device by using the bubbling air for an oxidizing tower or a part of a very small amount of compressed air to be used for other various driving sources. This construction serves to check the entering of exhaust gas containing sulphur oxide from the duct 1 into the emergency spray piping 14. Thus, even conventional high-class stainless steel that used to be corroded for a year or so is essentially prevented from corrosions. Even if ordinary stainless steel is used, it can be sufficiently resistive against corrosions.

Abstract: PURPOSE:To prevent moire from being generated and to prevent picture quality from being deteriorated by changing the pitch of a Fresnel mirror corresponding to a change in a picture element or the pitch of a scanning line to be projected on the surface of the mirror. CONSTITUTION:For respective mirror surfaces 2a of a Fresnel mirror 2, a pitch FP is enlarged from a right side to a left side so that a pitch FP1 of a part reflecting a video beam 11 toward the lower end of a screen 3 for projection can be minimum and a pitch FPn of a part reflecting the video beam 11 toward the upper end can be maximum. Since a pitch P of a projected scanning line 12 is gradually enlarged from the right side to the left side on the Fresnel mirror 2, the pitch FP of the mirror surface 2a is selected corresponding to the change in the pitch P of the projected scanning line 12. Thus, the moire is suppressed to be generated by a relation between the pitch of the Fresnel mirror 2 and the pitch of the picture element or the scanning line of a light source projected onto the mirror surface 2a, and the picture quality is prevented from being deteriorated.
