Title: Protecting method for motor driving circuit and protecting circuit
Inventor: YOSHITOMI TETSUYA
IPC: H02P7/288
Filed: 1990-07-30
Abstract: PURPOSE:To obtain a protecting method for a motor driving circuit capable of setting power consumption to zero and a protecting circuit in a motor standby state by braking the motor based on a detection signal of a detector when the temperature of a driving circuit for driving the motor is raised to a predetermined value. CONSTITUTION:When instruction signals IN1, IN2 are set to '1', '0', transistors Q2, Q3, Q4, Q5 are operated. Accordingly, a driving current in a direction (a) is supplied to a motor M, which normally rotates, and a monitor 6a monitors the chip temperature of an IC. If the chip temperature of the IC is raised to a predetermined value due to certain cause, transistors Q25, Q26 are simultaneously operated. Accordingly, the signals IN1, IN2 become equivalent to the states set to '1', '1', and the motor M is braked. Therefore, the IC is protected against damage due to the high temperature. Since a current supply source for a driver 3 and the motor 6a is commonly used, power consumption in the standby state of the motor M can be set to zero, and a chip size and its cost can be suppressed by suppressing an increase in the number of elements.

IPC: G06T7/00
Filed: 1994-08-29
Abstract: PURPOSE: To prevent a foreign object such as a smudge from being inspected as a mark in a mark inspection of the surface of a semiconductor. CONSTITUTION: Data on marks which contain foreign objects such as smudges subject to inspection, of image data of the surface of a semiconductor are stored in an inspection coordinates work area 1g. CPU 1d extracts a true mark from the data on the marks to be inspected in comparison with a mark size data area 1e and a threshold value data area 1f, and this is stored in a mark size confirmed coordinate area 1h. Then, quality inspection is conducted of the true mark data. Since the quality inspection is conducted only on those mark data in agreement with prescribed standards out of the mark data subject to inspection containing foreign objects such as smudges, there is less possibility of inspecting foreign objects such as smudges as marks.

Title: Document speech recognition device
Inventor: TANAKA HIROSHI
IPC: G10L15/06
Filed: 1988-08-18
Abstract: PURPOSE:To improve the recognition rate and increase the recognition speed by recognizing a paragraph in a sentence and a paragraph at the sentence tail which differ in characteristics by using different recognition standards. CONSTITUTION:When a document which is voiced is inputted from a speech input part 11, switching to an input switching part 15 is carried out according to whether or not a sentence tail signal generation part 14 generates a sentence tail signal. When no sentence tail signal is generated, the input switching part 15 switches the input to an in-sentence paragraph recognition part 13 which recognizes a paragraph appearing except at the tail of the document, but when the sentence tail signal is generated, the input switching part 15 switches the input to a sentence tail paragraph recognition part 12 which recognizes the paragraph appearing at the tail of the document. Then a document recognition part 16 recognizes the input as the document according to the outputs of the in-sentence paragraph recognition part 13 and sentence tail paragraph recognition part 12. Consequently, the recognition by the paragraph recognition parts is made accurate to improve the document recognizing performance.
