Title: Method and device for detecting foreign matter
Inventor: KOIZUMI MITSUYOSHI
IPC: G01N21/94
Filed: 1984-11-14
Abstract: PURPOSE:To detect fine foreign matter stably at a high speed distinctively from a circuit pattern by converging scattered light from a sample plane optically and detecting light passed through an analyzer, arranged in the optical path of the convergence, by a photoelectric converting element. CONSTITUTION:A wafer 1 while sucked to a wafer chuck 40 through a vacuum tube 41 is moved in XY directions by an X and an Y stage. Foreign matter information detected by a solid-state image pickup element array 20 reaches a control circuit 32 including a foreign matter memory 20 through a binary coding circuit and an OR circuit 22, and is displayed on a display device 33. Then, the size of a picture element is set to about >=5X5mum<2>, so if defocusing is caused by surface undulations of the wafer during inspection, the sensitivity of foreign matter detection decreases greatly. For the purpose, the quantity of the defocusing is detected by an automatic focus detection part 30 during the inspection and fed back to the driver 31 for a motor 43 for focus mechanism to prevent that.

Title: Method for detecting mis-reception of message
Inventor: ATAMI NOBUO
IPC: H04W84/02
Filed: 1990-09-10
Abstract: PURPOSE:To detect miss-reception of message quickly by allowing a transmission station to send a serial number notice signal comprising a serial number at a current point of time periodically and allowing a receiver to compare a serial number stored in a storage section and representing how many number the reception message is received with the serial number in the serial number notice signal. CONSTITUTION:A transmission station adds date information and signal identification information representing a signal to be a message signal to the message signal and a serial number notice section 13 sends a serial number notice signal comprising a selective calling number, date information, serial number and serial number notice signal after a date is changed periodically at an interval of, e.g. 2 hours based on a clock section 14. A receiver uses a separation section 22 to separate the message signal from the serial number notice signal, a serial number is being incremented by one every time a message reception section 23 receives the message signal and the result is stored in a serial number storage section 28 together with the date. Upon the receipt of the serial number notice signal, the serial number reception section 24 compares the serial number in the serial number notice signal with the serial number notice stored in the serial number storage section 28 and raises an alarm from a speaker 27 when they are different.

Title: Detecting device for body position
Inventor: TESHIGAHARA MASAKI
IPC: G01S13/42
Filed: 1984-11-13
Abstract: PURPOSE:To easily measure the position of a body to be detected from the frequency of a variable delay means by adjusting the frequency so that a detection wave from the object body is maximum. CONSTITUTION:Pulses P generated by a timing pulse generating circuit 2 are delayed successively by a specific time through a variable delay circuit 3 and transmitters 4A-4D are driven on the basis of respective delay pulses P1-P4 from the circuit 3 to send ultrasonic waves i1-i4 from an ultrasonic wave oscillator 4 for transmission. An ultrasonic wave (j) reflected by the body 7 is received by an ultrasonic wave oscillator 5 and sent to a signal processing circuit 6, and a peak value decision circuit 63 decides whether the level of the received signal attains to its peak value or not and outputs a voltage signal corresponding to the shift of the received signal from the peak value. A voltage-controlled oscillator 64 outputs a control signal (k) corresponding to this voltage signal and the clock frequency of a shift register 30 is varied until the transmission direction of the transmitted wave coincides with the direction of the body 7, thereby finding the direction theta of the body 7 from the clock frequency at which a stable state is obtained. Further, a time difference detecting circuit 65 calculates the distance to the body 7 from the difference between the generation time of the pulses P and the reception time of the received signal.

Title: Case for display body
Inventor: KATO SHINICHI
IPC: H05K5/02
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To secure a picture frame width from a necessary strength of a pair of cases for a liquid crystal display module. SOLUTION: An under case 1 is provided with a projecting part 4 on a specified inner side wall 3. An upper case 11 is provided with a leaf spring part 15 in the form of a cantilever on a specified side wall 14. In general, it is difficult from precision of machining to exactly fit the side wall of the upper case 11 to the side wall 3 of the under case 1. Although a maximal allowance is made for this reason, this may cause a play between both cases 1, 12. Therefore, if a projecting value of the projecting part 4 from the inner side wall 3 is made as same as the play, the left side wall 14 of the upper case 11 always fits to the side wall 3 of the under case 1 not only when there is no play between both cases 1, 11 at all but also when there is a play at a maximum between both cases 1, 11.
