Title: Starter switch signal abnormality detector
Inventor: CHIKAMATSU MASATAKA
IPC: F02N11/08
Filed: 1992-05-25
Abstract: PURPOSE:To detect abnormality of a starter switch signal by determining an ON or OFF state of a starter switch on the basis of the starter switch signal, and detecting a current for driving a starter motor. CONSTITUTION:When a starter switch 10 is turned on, a current flows in a starter magnet 8 from a battery 1 through an electric wire 5 so as to electrify a contact point. Accordingly, electric power is supplied to a starter motor 6 via another electric wire 4, thus rotatably driving the starter motor 6. A current flowing in a main electric wire 2 is detected by a current sensor 15, to be input into an ECU 13 after being amplified by an ELD 17. Meanwhile, a starter switch signal generated at the time of turning-on of the starter switch 10 is input into the ECU 13 through a starter switch signal line 11, whereby determining whether the starter switch is turned on or off. The existence of a starter current corresponds to the ON or OFF of the starter switch if the starter switch signal is normal. Consequently, abnormality is judged in the case of no correspondence.

Title: Ultrasonic measuring device for velocity of flow
Inventor: IZUMI GOROU
IPC: G01F1/66
Filed: 1981-10-03
Abstract: PURPOSE:To eliminate errors in measurement with respect to the change in velocity of  flow with time and to measure always the accurate velocity of flow continuously by  making common use of one set of wave transmitter and receivers in plural sing-around  systems and transmitting and receiving the ultrasonic wave pulses in the flow direction  of fluid and in the direction opposite therefrom simultaneously. CONSTITUTION:The pulse signals of frequencies f1 and f2 are transmitted through respective hybrid transformers HYB to wave transmitters and receivers 41a and 41b.  After the dignal f1 is converted to ultrasonic wave pulses with the transmitter and receiver 41a, the pulses are transmitted to the transmitter and receiver 41b. Similarly  the signal f2 is transmitted to the transmitter and receiver 41a after conversion. The  pulses received in the transmitter and receivers 41b and 41a are converted to electric  signals which are transmitted through the respective HYBs to sing-around systems 20  and 30. The signal f1 is transmitted through a BPF22, an amplifier 23, a detector 24  and a waveform shaping circuit 25 to a signal transmitter 21 and a counter circuit 44  to count up the circuit 44 by one. The signal f2 counts up the circuit 45 similarly. The  respective count values are subtracted by repetition of such operations for a prescribed  time, whereby the velocity of flow of fluid 10 is determined.

Title: Lifting control method for hack sawing machine and device thereof
Inventor: SAITO SHUICHI
IPC: B23D55/08
Filed: 1985-07-17
Abstract: PURPOSE:To prevent a saw blade from going up unnecessarily at every cutting completion as well as to make improvements in cutting work efficiency, by resetting the saw blade after cutting a work up to a separate position in making it go higher as far as a proper interval than the work. CONSTITUTION:A position where a saw blade 1 comes into contact with a work 3 in its descending stroke is detected by a work detecting device 5, storing it in a memory. When the saw blade 1 is further goes down, cutting the work 3, and these operations are detected by a down position detecting device 7, the saw blade shifts to its ascending stroke. In this ascending stroke, if it accords with the contact position of the work 3 at the time of descending, a setting time starts with a signal out of a transmitting device 11. If so, the saw blade 1 goes up as long as the specified setting time long, and if it comes off an upper end of the work 3, stopping its upward motion, and waits for the next cutting stroke. With this constitution, an ascent stopping position of the saw blade 1 is automatically determined by height and thickness of the work 3, and thereby it stops at the setting height position as specified from the upper end of the work 3 so that the saw blade 1 is prevented from going up unnecessarily at every cutting completion, thus cutting work efficiency is improvable.

Title: Mos field effect transistor
Inventor: SAKAMOTO MITSURU
IPC: H01L29/06
Filed: 1977-12-28
Abstract: PURPOSE: To obtain a short-channel, highly-integrated and high-capacity transistor by making convex source and drain regions in comparison with a gate oxidized film part and by forming low-density regions partially in source and drain regions.  
     CONSTITUTION: After SiO 2  films 102 and 103 are formed, N-type Si is epitaxy- formed on P-type Si substrate 101, so that poly-Si will be formed on films 102 and 103. Selectively etching the poly-Si layer making use of a difference in etching speed allows single crystals of swelling source and drain regions 104 and 104', and 105 and 105' to remain. Next, the surface is covered with SiO 2 106 and gate electrode 107, and source and drain electrodes 108 and 109 are formed. With the density of layer 105 made at least equal to or less than that of the P-type substrate, the depletion layer of the junction between layers 101 and 105 expands toward layer 105 when drain 109 is applied with a voltage and since it will not expand toward the substrate as usual, deterioration in source-drain dielectric strength as a channel is shortened can be prevented, so that a degree of integration will increase because of the logitudinal structure.

Filed: 1980-11-11
Abstract: PURPOSE: To prevent the creaking of a brake for long term, by arranging a slide means between a caliper shoulder section approximately perpendicular with the brake face of a braking disc and the side end section of a padd backplate.  
     CONSTITUTION: Both end sections of a padd backplate 5 are arched 51 while a cap 7 is applied loosely on said arched section 51 thus to contact the outside wall of the cap 7 against the shoulder section 31 of the caliper 3. The arched section 51 of the padd backplate 5 and the cap 7 will constract a sliding means 8 and when a disc 1 will swing to the direction of the thickness at the braking, the padd 6 and the backplate 5 are slided freely by means of the sliding means. Consequently the friction speed gradient between the shoulder section 31 and the arched section 51 of the caliper 3 will be zero or positive thus to prevent the self-excited vibration due to the friction between the padd backplate 5 and caliper 3 thereby the creaking of the brake can be prevented.

Title: Microscope for measurement and inspection
Inventor: TAKEUCHI ATSUSHI
IPC: G02B21/06
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain a sample image of a good contrast with simple constitution even if periodic patterns near the resolution threshold exist on a sample by forming the illumination light with which the sample is irradiated as linearly polarized light in the same direction as the periodic direction of the periodic patterns. SOLUTION: The sample having the periodic pattern PT1, PT2 in X- and Y- directions where the periodic directions intersect orthogonally with each other is irradiated with the light R of the linearly polarized light in the X-direction. When the periodic patterns PT1, PT2 are illuminated with the light R of the linearly polarized light in the X-direction, the contrasts of the images obtd. when the periodic direction and the polarization direction are aligned and when the periodic direction intersects orthogonally therewith vary. Then, the light is more liable to infiltrate the grooves and the phase modulation of the light by the grooves is larger with the patterns PT1 of which the periodic direction and the polarization direction are aligned with respect to the periodic structure consisting of raggedness. Consequently, the contrast of the image is intensified.  When, therefore, the structure in the periodic direction is measured and inspected, the structure is deliberately illumination with the linearly polarized light in this direction.

Abstract: PURPOSE: To control tension of a foil by fixing a foil applied with an initial tension while supporting at the opposite ends of an arcuate bimetal and providing the foil with a strain gauge for measuring the tension being applied to the rotary shaft thereby varying the set value of a variable power supply for heater automatically. CONSTITUTION: Tension of a foil 1 is measured by means of a strain gauge 3 and a measurement is delivered through an amplifier 4 to an automatic controller 5. When the measurement has abnormal value, current from a variable power supply 6 is increased and a planar bimetal 8 is heated by means of a heater 7 thus bending the bimetal 8 to project outward. Consequently, arcuate bimetal 9 secured to the planar bimetal 8 and the foil 1 are retracted in the radial direction thus controlling the tension within a correct range. Furthermore, a rotating machine is provided with a vibrometer 10 in order to determine the magnitude of vibration.  When the vibration deviates from a set range, a heater 11 is heated through the automatic controller 5 to decrease the radius of curvature of arcuate bimetal 9 and to increase the lap angle θ thus controlling the tension of foil 1 and the lap angle θ constantly within a correct range.
