Title: Fuel injection control device of internal-combustion engine with supercharger
Inventor: YOSHIOKA MAMORU
IPC: F02D23/02
Filed: 1985-06-20
Abstract: PURPOSE:To improve drivability during acceleration, by a method wherein a moderating value of a ratio of an intake air amount to the number of revolutions, serving as a basis of a calculation value of a fuel injection amount, is changed depending upon the operating state of a supercharger. CONSTITUTION:A means 7 of computing a moderating value of a ratio Q/N of an intake air amount to the number of revolutions computes a moderating value of Q/N based on the number of revolutions and an intake air amount, detected by an intake air amount detecting means 5 and a number of revolutions detecting means 6, and the state of a supercharger 3 detected by a supercharging state detecting means 4. The value serves as a basis of calculation of a fuel injection amount, and a fuel injection control means 8 controls a fuel injecter 2 so as to obtain a fuel injection amount responding to the Q/N moderating value. This maintaines an air-fuel ratio at a specified value through the feed of an air amount optimum to an internal-combustion engine 1 in response to the operating state of the supercharger 3, and enables improvement of drivability despite of a change in the working condition of the supercharger 3.

Title: Transmission type microscope
Inventor: ICHIE KOJI
IPC: G02B21/00
Filed: 1990-05-23
Abstract: PURPOSE:To increase the difference in brightness of a transmission image to improve the contrast by arranging an infinity correcting objective lens, a telecentric image forming lens, and a plane mirror on the same optical axis to allow light to pass a sample twice. CONSTITUTION:The light transmitted through a sample 12 is converted to parallel rays by an infinity correcting objective lens 13 and is made incident on a telecentric image forming lens 14. This light is emitted to a plane mirror 15 so that the principal ray of this luminous flux is parallel with the optical axis. The plane mirror 15 reflects the light emitted from the telecentric image forming lens 14 and makes the reflected light incident on the telecentric image forming lens 14 again. The light emitted from the telecentric image forming lens 14 is made incident on the infinity correcting objective lens 13, and the sample 12 is illuminated from opposite directions by spot light formed in the same position of the sample 12 by this lens 13. Since light passes the sample twice in this manner, the difference in brightness of the transmitted image is made distinct to improve the image contrast.

Abstract: PURPOSE:To prevent a command signal from increasing too much by replacing integration with a stable transfer function for a specific converted value through a 1st and a 2nd computing element and an adder, and determining an upper limit and a lower limit by a limiter for the command signal outputted from the adder. CONSTITUTION:The deviation (e) of a detection signal 5 from a target signal 8 is found and a subtracter 9 outputs a deviation signal 10 corresponding to the deviation (e); and the deviation (e) is converted on the basis of the deviation signal 10 by using a relation u1(s)/e(s)=1/(s+a) to find a converted value u1, whose converted value signal 14 is outputted by the 1st computing element 13. Then the sum of the converted value u1 of the converted value signal 14 and the value of a specific signal is found and a command signal is outputted by an adder 10. The limiter 18 limits the command signal 6 so that it does not exceed the upper limit and lower limit. On the basis of the limitation, a converted value u2 is found from a relation u2(s)/q(s)=a/(s+a), where (a) is a manipulated variable; and a converted value signal 17 is outputted by the 2nd computing element 16, and both the converted values u1 and u2 are found by the adder 15.

Title: Light integration circuit device
Inventor: TOMIOKA TAZUKO
IPC: H01S5/022
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent crosstalk due to stray light, by using a semiconductor substrate with a wavelength that is equal to or longer than the emission wavelength of a light-emitting element as a band gap wavelength on an integrated circuit substrate. SOLUTION: InGaAsP light-emitting element 2 and a light reception element 3 are formed, via InP layer 4, on a substrate with a band gap wavelength that is longer than the emission wavelength of the light-emitting element 2 in 1.3-1.5 μm band, for example, InAs substrate 1 as a semiconductor laser element. The light-emitting element 2 is normally formed for example, by InGaAsP, and a light reception element 3 is normally formed by an element such as InGaAs. As a result, stray light from the light-emitting element 2 is absorbed by the substrate 1 while it advances through the substrate 1 and hence cannot reach the light reception element 3, thus achieving a structure where no light crosstalk occurs and obtaining improved light reception characteristics.

Abstract: PURPOSE:To correct characters with a simple means by writing the correction information such as a prescribed lateral line, etc. on a character which is written erroneously. CONSTITUTION:If some of written characters has an error, the correction information of a lateral line 51 is written on the wrong characters. Both characters and the correction information 51 on a slip 50 are converted into binary video signals VD and stored to a line buffer 21. Then the character pattern in the buffer 21 is demarcated every character and transferred to a demarcated buffer 22 and then to a character recognizing part 23. Thus characters are recognized. While it is decided that the correction information exists and the characters written at the upper side of the line 51 are regarded as correct ones in case the projection information is equal to a continuous projection 41 equivalent to the line 51.

IPC: B65G53/04
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce a pressure loss as a whole, damage of a granular and powdery material and abrasion of a transport pipe by providing a guide plate for adding a flow component in the circumferential direction of the transport pipe to the flow of granular and powdery material parallel to the transport pipe, thereby letting a stream at the bottom of the pipe flow to the upper part of the pipe along the inner surface of the pipe. SOLUTION: A guide plate 4 is provided at the bottom of the pipe in an area where a granular and powdery material 2 is concentrated on the bottom of a transport pipe 1, thereby adding a flow component in the circumferential direction 6 of the transport pipe 1 to a stream 3 at the bottom of the pipe which has flowed parallel to the transport pipe 1 heretofore to carry the stream 3 at the bottom of the pipe to the upper part of the pipe 1. The upper part of the pipe 1 and the bottom of the pipe 1 are partitioned by the guide plate 5 to keep the granular and powdery material 2 carried to the upper part of the pipe from being again moved to the bottom of the pipe 1 by the circumferential flow 6.  Thus, the flow of the powdery and granular material 2 becomes a flow 3 parallel to the transport pipe 1 to keep the granular powder 2 at the upper part of the pipe 1, thereby reducing a fluid speed.

Title: Power source equipment
Inventor: SUZUKI KOJI
IPC: H02J3/02
Filed: 1988-06-02
Abstract: PURPOSE:To produce a plurality of high voltage outputs having different output timing from a single transformer by arranging an output control element and a voltage doubler/rectifier at the secondary of a booster transformer and lapping an AC voltage produced through the output control element at a control point over the output from the voltage doubler/rectifier. CONSTITUTION:During an interval when a transistor Q3 is turned OFF, a capacitor C9 is charged only and voltage doubling/rectifying operation is not carried out thus producing no DC component at terminal J2. When the transistor Q3 is controlled into conducting state, clamping operation is carried out through a clamper comprising a capacitor C8, the transistor Q3 and a diode d2, and the collector has a DC level shifted output. This AC signal is rectified and lapped over the output from a booster transformer T1 through a capacitor C7 for voltage regulation and DC cut, thus producing a DC output at the anode of a diode D9. By such arrangement, the size and the weight of the power source section are reduced resulting in cost reduction.
