IPC: G02B27/09
Filed: 1993-08-31
Abstract: PURPOSE:To minimize the spot size of a laser beam, enhance the focus depth, and project a sample having a deep groove structure with a good resolution to make the dimensional measurement possible. CONSTITUTION:A laser beam 20 is straightly advanced in a beam splitter 23 and emitted to an axicon prism 27. The spot size of the beam 20 is reduced to about 2mum by the prism 27, and narrowed to an extremely small spot size by a relay lens 28. The beam 20 is reflected 29, emitted to an objective lens 30, narrowed to about 0.2mum thereby, and focused on a sample surface in a scanner 31. When the dimension of the groove part of the sample is inspected, the focus position of the beam 20 is fixed according to the groove bottom part, and the sample is moved by a scan controller 32 to make the beam 20 scan within a prescribed observing area. The laser beam intensity entered to a photomultiplier 26 is different between the times when the beam passes the groove bottom part and the sample surface. Thus, the illuminance according to the output of the photomultiplier 26 is successively drawn, and much image information for the groove inner part is projected to a television monitor to automatically measure the pattern width of the groove.

Title: Controller for hot wire type air flowmeter
Inventor: MURATA MASARU
IPC: G01F1/698
Filed: 1986-09-12
Abstract: PURPOSE:To hold a hot wire clean all the time and to contrive to prolong its life without spoling the reliability by supplying a large current to the hot wire when a run time or run distance reaches a set value during a run and burning out foreign matter sticking on the hot wire. CONSTITUTION:For example, a run time counter 35 reaches its set value, its output signal is inputted to an OR circuit 38, which inputs a burning-out signal to driving circuit 34. Consequently, this circuit 34 supplied a driving pulse to the base of a transistor T1 connected between connection points D and B of bridge circuit 30 to turn on the T. Consequently, the bridge circuit 30 enters an unbalanced state and a current flowing to a register R3 decreases, so that the base current of the transistor T2 of a current control circuit 31 decreases. Consequently, the collector-emitter voltage VCE of a transistor T3 rises and a current flowing to a resistance R5 decreases. Further, a current from a constant voltage VB increases in the bridge circuit 30 to the contrary and the hot wire RH reaches high temperature to burn not the sticking matter.

Title: Intake system for internal combustion engine
Inventor: SHIBATA HARUSUKE
IPC: F02D9/10
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To improve the engine torque by a simplified configuration. SOLUTION: A tip side part 7b of a branch pipe 7 of an intake manifold 6 is bent downward, a surge tank 8 is connected to the tip side part 7b, and a throttle body is offset so that it is out of a lengthening direction X. Since the tip side part 7b is bent downward and the branch pipe 7 becomes longer that much, the torque of an engine 1 in low, medium speed area can be improved. Further, by bending the tip side part 7b downward to improve the torque of the engine 1, a space between the branch pipe 7 and the engine 1 can be effectively utilized. Since the throttle body is offset so that it is out of the lengthening direction X, and thus the length of an intake pipe 10 is increased that much, transmission of vibration of the engine to a car body can be suppressed.

Title: Fault detection circuit for thyristor converter
Inventor: KIMURA YOSHIO
IPC: H02M7/12
Filed: 1988-08-30
Abstract: PURPOSE:To obtain a fault-detection circuit with a high reliability by comparing a current reference signal and a current feedback signal for obtaining a fault- occurring signal. CONSTITUTION:A current feedback signal CFB is inputted to the (-) terminal of a comparator 5 and a current reference signal REF, to the (+) terminal thereof; and a relay RY is connected with the output terminal VO of said comparator. Then, said comparator 5 compares the current reference signal REF set by a reference signal generator 2 and the current feedback signal CFB being the output signal of a current sensor C5 detecting the output current of a thyristor converter 1; and when the output current exceeds a set value, the relay RY operates to output a fault-occurring signal. In this manner, because said thyristor converter 1 supplying a reactor load L such as the field coil of a DC motor with electric current is caused to detect an overcurrent, it is possible to prevent the breakdown of thyristor elements TH1-TH4, burning of said field coil, etc.
