Title: Mechanical supercharger
Inventor: SUGIMOTO KAZUO
IPC: F02B33/40
Filed: 1987-10-14
Abstract: PURPOSE:To make a clutch to stop the operation of a supercharger and a belt to drive the supercharger unnecessary and make the supercharger compact by directly driving the mechanical supercharger arranged on an intake system with a rotating speed controllable motor. CONSTITUTION:A mechanical supercharger 1 is provided in the middle of the intake pipe 7 of an internal combustion engine, and a driving motor 2 is directly coupled with its rotary shaft. The rotating speed of this driving motor 2 is controlled by a motor drive control circuit 3 connected with an alternator 4 and a power improvement request signal detector 8. When an accelerator pedal is deeply depressed (at the time of the high load for an engine), for example, this depression quantity is detected by the power improvement request signal detector 8 and converted into the control signal and fed to a motor drive control circuit 3, the supercharger is controlled based on this control signal so that the rotating speed of the driving motor 2 is increased by the current from the alternator 4, thus the supercharged quantity is increased.

Abstract: PURPOSE:To make the bulk density in a dried gel material uniform and produce a preform for optical fibers in high yield, by forming a core material and clad material using sol solutions containing an alkyl silicate and fine silica particles in different proportions. CONSTITUTION:A sol containing an alkyl silicate and fine silica particles as main raw materials is gelatinized into a cylindrical shape to form a clad material. A doping material required for the above-mentioned sol is then cast into a hollow part of the clad material and gelatinized to form a core material. The prepared integral clad.core gel is then dried and sintered to provide the aimed preform for optical fibers. In the above-mentioned sol-gel method, the proportion of the alkyl silicate and fine silica particles are respectively adjusted between the sol solutions in both layers according to the amounts of the above- mentioned doping material and properly varied. Thereby the volume shrinkage rate and bulk density of the clad and core layers in drying are made uniform to suppress the occurrence of breaking or cracking and improve the yield of the dried gel.

Abstract: PURPOSE:To provide property rigidity, resilience and easiness of bending by folding a planar member, made of numerous crimped staple aggregates subjected to needling in the direction of thickness, vertically, alternately and sucessively into a corrugated continuous form and holding the planar member. CONSTITUTION:A needling machine 1 needles a needle 3 into an aggregate 2 in the direction of the thickness to constitute a planar member 4 which has a cushion property small in the direction of thickness and large in the expanding direction orthogonal to the direction of thickness. This planar member is first folded vertically successively to form a corrugated member 4' having the vertical parts in contact continuously with each other and form the bend parts 6 and contact parts 7. Next, the corrugated members disposed on two upper and lower stages are combined to align the continuously contact parts longitudinally with each other. In this method of combination, a sheet member 9 is interposed between the upper and lower corrugated members to glue both members. Thus, a cushion member 5 serves substantially as an almost single continuously contact member and provides a firm cushion material without being deformed since the thin corrugated members are constituted on two stages.

Title: Evaluating device for optical disk
Inventor: TSUCHIYA YOICHI
IPC: G01B11/30
Filed: 1985-11-20
Abstract: PURPOSE:To evaluate the optical deformation of an optical disk by irradiating a laser beam disabled to be recorded and detecting the reflected light. CONSTITUTION:The intensity of a laser beam radiated from a light source 12 is set up to comparatively weak intensity which can not be probably recorded on the disk as information. The reflected light from the disk 20 is made incident upon a position detecting photosensor 22 through a 1/4 wavelength plate 18 and a beam splitter 16. When the disk 20 is warped by an angle theta e.g., the reflected light is shifted from the irradiation light upon the disk 20 by an angle 2theta. In this case, the optical point of the reflected light is shifted from the center of the photosensor 22 by a distance corresponding to the angle 2theta. In accordance with the shifted distance, outputs are obtained from the terminals 22a, 22b of the photosensor 22. Thereby, the optical deformation of the disk 20 such as warp can be evaluated on the basis of the outputs from the photosensor 22.

Title: Judging device for deterioration of air-fuel ratio sensor of internal combustion engine
Inventor: FURUKUBO KENJI
IPC: G01N27/409
Filed: 1994-09-30
Abstract: PURPOSE: To make judgement of deterioration with less error in an air-fuel ratio sensor even though the operating condition of internal combustion engine differs, by turning the deterioration judgment values into tabulated values by the use of suction air amount. CONSTITUTION: An air flow meter 22, O2 sensor 24, and engine speed sensor 26 are connected with a control means 28. Judgement of deterioration of the O2 sensor 24 is made by monitoring the inversion period and/or the time in which the voltage signal given by the O2 sensor 24 changes, during the feedback control of the air-fuel ratio. If the deterioration judgement value for a variable used in the deterioration judgement is fixed to be one constant, the probability of erroneous judging is heightened. Thereby, the deterioration judging accuracy can be enhanced by turning these deterioration judgement values into tabulated values. The tabulated values for deterioration judgement are set so as to lessen with increment of the suction air amount.
