Title: Ignition timing control device for internal combustion engine
Inventor: SHIBAGAKI NOBUYUKI
IPC: F02M25/07
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of knocking caused by the excess advance of ignition timing at the switching time of a combustion method. SOLUTION: When the combustion method of an engine 11 is switched from uniform charge lean combustion to weak stratified charge combustion, ignition timing is advanced in response to the increase of an ERG amount with the increase of a required ERG amount. After the switching of the combustion method, current ERG amount and the required EGR amount at the weak stratified charge combustion approach mutually gradually with the lapse of time. The difference between the required ERG amount and the current ERG amount changes corresponding to the response delay of an ERG valve 43 at the switching time of the combustion method. The actual ERG amount change against the opening degree change of the ERG valve 43 has also response delay. Therefore, the electric control unit of the engine 11 computes an ignition timing delay amount based on the difference between the required EGR amount and the current ERG amount at the switching time of the combustion method, and the computed ignition timing delay amount is delayed by a predetermined time so as to reflect into the delay angle correction of the ignition timing.

Title: Multi-layer film mirror and spectroscope
Inventor: KIHARA NAOTO
IPC: G01J3/12
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To obtain a mult-layer film mirror getting in which the light having a wavelength ratio of a rational number mixed into the transmitted/reflected light flux to be used is principly eliminated by laminating many layers of a unit alveolus so that the array of the thickness of easy unit alveolus may be provided with quasi-periodicity. SOLUTION: Many unit alveoluses 2 are laminated on the surface of a plane substrate 1. The thickness of each unit alveolus are two kinds d1 and d2 in the relation of d2 /d1 =1+1/τ by using an optional irrational number:τ and these two kinds of the thicknesses d1 and d2 are arrayed to form a fibonacci series to generate multi-layer film structure. Then parallel fluxes made incident at an incident angle θin are reflected by the unit alveoluses 2 and the mutual ration of the wavelengthes of light in reflected light fluxes emitted at a reflecting angle θout is always a rational number to remove light whose wavelength ratio is an irrational number. A reflecting-type multi-layer film mirror is used here but it can equally be applied to a transmitting-type multi-layer film mirror. In addition the kinds of thicknesses can be not less than three kinds.

Title: Fault annunciator
Inventor: SUGITA KIYOKO
IPC: H04L69/40
Filed: 1988-12-21
Abstract: PURPOSE:To attain annunciation of occurrence of new fault even if the annunciation of a preceding fault is consecutive by monitoring a state of a fault taken place transited from a normal state to an abnormal state and annunciating the occurrence of a fault to the operator when the transition pattern is coincident with a preset check pattern. CONSTITUTION:An output signal from a fault detection circuit 6 is inputted at a prescribed period and stored in a monitor state latch circuit 4. A check circuit 3 storing detection patterns discriminates whether or not the digital signal inputted to the monitor state latch circuit 4 is coincident with the check pattern signal. In the case of coincidence, it is discriminated that a disconnection fault of the circuit takes place and a high level signal representing 'fault occurrence signal' is outputted to a notice circuit 5. Thus, every time a fault takes place, the occurrence of fault is informed to the operator.

IPC: G06F11/22
Filed: 1987-12-24
Abstract: PURPOSE:To prevent useless system down or the like and to improve the fault detecting ratio of the whole checking circuit by using a check validity signal and invalidating the error detection when operation to be executed by an arithmetic circuit is invalid. CONSTITUTION:A modulo 3 circuit 1 inputs 2-bit data D=(d1, d2), a check validity signal S and a strobe signal STB and outputs 2-bit data E=(e1, e2). When the effectiveness of error detection is indicated by the check validity signal S=1, an output obtained after inputting the signal STB in the case of D=(1, 1) or E=(1, 1) is fixed always on (1, 1) and the generation of a fault in a circuit arranged before the circuit 1 is detected. If the signal STB is inputted when the invalidity of error detection is indicated by the signal S=0, the output E is held in the state obtained before the input of the signal, so that the inputted result of error detection is invalidated. Consequently, the generation of useless system down can be prevented and the fault detecting ratio of the whole check circuit and resolution after error report can be improved.

Title: Extruding tool for indirect extrusion
Inventor: KUROZU AKIO
IPC: B21C25/02
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To improve the surface quality of an extruded material and to prevent variation in dimensions in indirect extrusion. SOLUTION: On the circumference of the outer peripheral surface 23 of the straight part of a die ring 22 for indirect extrusion, plural flat parts or grooves are formed so as to partially increase the clearance with the inside wall of a container 4 and by flowing out metal during extruding and trapped air in the vicinity of the inside wall of the container from this clearance, the surface of the extruded material is prevented from entraining them. Frictional resistance with the inside wall of the container 4 is reduced in the flat part or groove part, so the clearance with the inside wall of the container 4 can be reduced by making the outside diameter itself of the outer peripheral surface 23 larger corresponding to the decrease.  As a result, the deviation between the die ring 22 during extruding and the axial center of the container 4 becomes smaller and the variation in the dimensions of the extruded material is prevented.
