Title: Intake air flow detection device for internal combustion engine
Inventor: FURUKAWA SATORU
IPC: F02D45/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To detect intake air flow with precision by compensating for response lag and counterflow components in the output of thermal air flowmeters. SOLUTION: A response lag compensating model for compensation for response lag in bypass type thermal air flowmeters is used to compensate for the response lag in a thermal air flowmeter output VG or calculate a true bypass flow. A fluid motion model for the simulation of the relationship between a bypass flow and a mainstream flow is next used, to process the true bypass flow or compute a mainstream flow. The pulse waveform of the mainstream flow has a discrete normal-flow and counterflow crests.  At prescribed time intervals, the maximal and minimal values of that latest region of the mainstream flow pulse waveform which corresponds to a preset crank angle are detected, so that crests and troughs are discriminated, with one having the largest maximal value out of all the crests being found as a normal-flow component and ones sandwiching the normal-flow component found as a counterflow component. Thereafter, the mainstream flow is compensated for the counterflow components, and a true intake air flow amount is found.

Abstract: PURPOSE:To perform a coating and drying operation easily and efficiently even for a short length pipe also by a method wherein in a ring of a desired diameter which is opened partially, the aperture of the opening is expanded and a temporary pipe joint provided with a retractive expander is employed. CONSTITUTION:In a ring 3 comprising a joint device J, the opening a of the ring is the narrowest when no external force is given, therefore, the diameter of the ring is the smallest. In this state, the joint device is inserted into the ends of pipes P1, P2, the ends 20, 20' of the ring 3 are expanded until the ring 3 comes to be pushed against the inner surfaces of the pipes P1, P2. Thus, pipes P1, P2 are connected and sent to a coating and drying device. After being processed at the coating and drying device, the joint device is removed by reducing the diameter of the ring 3. Thus, the coating and drying operation can be performed easily and efficintly by connecting pipes though they are short in length.

Title: Abnormal detector for rolling bearing
Inventor: SAKO KOJI
IPC: G01M13/04
Filed: 1985-06-14
Abstract: PURPOSE:To surely detect the abnormality of a rolling bearing by converting the mechanical oscillation generated from the rolling bearing under rotation to an electrical signal by using an acceleration sensor. CONSTITUTION:The acceleration signals detected by the acceleration detector 1 is converted in an electric charge change to a voltage signal in a charge amplifier part 2 according to need and is inputted to a band pass filter 3. The output from the filter 3 is converted to an absolute value signal by an absolute value circuit 4 and is inputted to an averaging circuit 5 and a peak detecting circuit 6. The circuit 5 smooths and averages the absolute value signal and detects the average value. The output from the circuit 4 is analyzed by a spectrum analyzer 7, by which the frequency component is measured. The frequency components of 1-8kHz are affected by the intermeshing oscillation of gears, etc. and the exact diagonosis is sometimes difficult with such frequency components in the diagnosis of overdriving and speed reduction gears, etc. The low limit frequency is therefore determined at 9-10kHz. Noticeable spectra are not generated in all of the abnormality in >=30kHz frequency components. There is therefore no need for detecting >=30kHz components.

Title: Mos type field effect transistor
Inventor: EDAMATSU JIYUICHI
IPC: H01L29/10
Filed: 1981-08-20
Abstract: PURPOSE:To reduce the junction capacity of the source and the drain of an MOS field effect transistor by forming a high impurity density region having the same conductive type as a substrate in the substrate directly under a gate film, thereby preventing a punch-through phenomenon. CONSTITUTION:An MOS field effect transistor having the same structure as the conventional one is formed as shown on a semiconductor substrate 10 formed with an epitaxially grown layer 12 and high impurity density regions 11, 17. Since the impurity density of the layer 12 is formed relatively small in this structure, depletion layers 14, 16 are largely expanded, with the result that the junction capacity of the source and the drain can be reduced. Since the regions 11, 17 are, on the other hand, formed on the section direcly under a gate 18, the expansion of layers 14, 16 of the source and drain junction toward the channel side is suppressed. Accordingly, the depletion layers of the source and drain junction are connected to each other, and a punch-through phenomenon can be prevented.

Title: Production of photo exposure mask
Inventor: MORI KATSUMI
IPC: G03F1/80
Filed: 1977-10-27
Abstract: PURPOSE: To produce an optical mask having fine positive type patterns by making combination use of electron beam exposure techniques capable of making fine working and dry etching of good selectivity.  
     CONSTITUTION: A Si light shield film 4 of a sufficient thickness is provided on a glass substrate 5, and positive type resist PBS of a high rate of dry etching but of a high resolving power is spin-coated thereon and is then baked. Desired positive type patterns 1 are created by performing exposure and development. Next, the surface is covered with optical resist 3 of a rate of dry etching smaller than that of PBS, then serrations are greater at the pattern edge. Next, the surface is sputter etched by CF 4 . If OMR-83 is used for the resist 3, the OMR-83 of the surface is first etched because its rate of etching is 1/15 that of PBS. When PBS exposues, PBS is etched extremely fast and the remained patterns become the negative patterns of OMR-83. When etching is done further, desired fine positive patterns of the film 4 may be readily formed.
