Title: Single-screw grinding and polishing grain-milling machine
Inventor: NAKAMURA KAZUO
IPC: B02B3/06
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized and inexpensive single-screw grinding and polishing grain-milling machine. SOLUTION: In a single-screw grinding and polishing machine 10, spiral ridges 40A are formed to the peripheral surface of a grinding rice polishing roll 40 and abrasive grain 40B are fixed thereto. A polishing grain-milling roll 56 having parallel ridges 56A formed to the peripheral surface thereof is integrally connected to the lower part of the grinding grain-polishing roll 40 on the same axis and a motor is connected to the lower part of the polishing grain- milling roll 56. Since feed force can be applied to grain in an axial direction by the spiral ridges 40A of the grinding grain-polishing roll 40, the blocking of grain on the periphery of the grinding grain-polishing roll 40 can be suppressed.  By this constitution, the peripheral speed of the grinding grain- polishing roll 40 may be almost the same as that of the polishing grain-milling roll 56 and, therefore, the single grinding and polishing machine 10 can be made inexpensive because of only one motor and the diameter of the grinding grain-milling roll is made the same as that of the rubbing grain-milling roll 56 to miniaturize the single screw grinding and polishing apparatus 10.

IPC: F02P5/153
Filed: 1991-09-20
Abstract: PURPOSE:To perform constantly excellent decision of the occurrence of knocking not depending upon unevenness in manufacture and deterioration with age by accumulating vibration data where no knocking occurs and vibration data where knocking occurs, and deciding the occurrence of knocking through comparison of the two data with each other. CONSTITUTION:A control unit 9 receives detection signals from an intake air amount sensor 2, a crank angle sensor 12, and a vibration sensor 17, etc., and computes an ignition timing and a fuel injection amount.

Further, the magnitude of a vibration component responding to a crank angle in an ignition timing range in which knocking is supposed to take place, so as to be stored. A difference or a ratio between the magnitudes of the abovementioned vibration components is determined. By deciding whether or not knocking characteristics represented by taking the difference or the ratio are contained in vibration data provided each time ignition, the occurrence of knocking is decided.
Patent JP-H0288362-A (JP)
Title: Power steering device
Inventor: MORISHITA MITSUHARU
IPC: B62D5/04
Filed: 1988-09-26
Abstract: PURPOSE:To obtain stable steering feeling even at a high speed travel and prevent the excessive turn of a steering wheel in sudden steering by limiting the current value of a motor with an increase in vehicle and engine speeds on the basis of the output voltage of the first and second frequency-voltage conversion circuits, and using the output voltage of the aforesaid conversion circuits as the power voltage of potentiometers. CONSTITUTION:The voltage of the first frequency-voltage conversion circuit 45 giving lower voltage with a vehicle speed increase is supplied as the power voltage of potentiometers 2b and 2c. As a result, motor current for steering torque comes to decrease with an increase in vehicle speed. Consequently, too light steering is not caused even at a high speed travel and stable steering feeling is obtained. Furthermore, a current flow to a motor 10 is limited to a low level with an increase in vehicle or engine speed on the basis of the output voltage of the first or second frequency-voltage conversion circuit 45 or 46. Consequently, an auxiliary energizing force with the motor 10 comes to be limited and the excessive turn of a steering wheel does not take place even in sudden steering during high speed travel.

Title: High pressure electric-discharge lamp
Inventor: IIDA TAKENOBU
IPC: H01J61/56
Filed: 1983-12-23
Abstract: PURPOSE:To secure the operation of a high voltage electric-discharge lamp by preventing any breakage of a ceramic capacitor which is a component of a starter by adjusting the rising point of the changes in the resistance of a positive-characteristic thermistor to be below the curie point of the ceramic capacitor. CONSTITUTION:A starter formed by connecting a ceramic capacitor 5 having a nonlinear characteristic and a positive-characteristic thermistor 6 the resistance of which is increased by the heat produced during the lighting of a high voltage electric-discharge lamp in series, is installed in an outer bulb 7 or a base. The rising point of the changes in the resistance of the positive-characteristic thermistor 6 is adjusted to be below the curie point of the ceramic capacitor 5. As a result, the production of high-voltage pulse voltage during the starting is secured. Furthermore, during the lighting of the lamp, the production of pulses by the ceramic capacitor 5 is reliably stopped. Accordingly it is possible to secure the operation of the lamp by preventing any breakage of the capacitor 5.

IPC: H01L21/66
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent the visual field of a microscope from moving outside an object to be inspected or an inspection area, so that the operability of stage driving is improved. SOLUTION: This microscope has a stage capable of driving in XY-direction, and an optical system enlarging the object to be inspected placed on the stage. A stage driving control part instructs the driving of the stage in response to driving operation input and also inputs the positional information of the stage. The stage driving control part decides stage movable ranges 62 and 64 in accordance with the input information related to the inspecting range of the object to be inspected, and inhibits stage driving with respect to the driving operation input instructing the movement toward the outside of the stage movable ranges 62 and 64.  By this method, the stage movable range is set in accordance with the inspecting range of the object to be inspected, and the stage is inhibited from moving outside the range, so that the visual field range of the microscope is prevented from moving outside the inspecting range of the object to be inspected, and the operability is improved even though the microscope is operated in the case of the observation with high magnification.
