Title: Mounting structure of semiconductor integrated circuit and mounting board used therefor
Inventor: KISHIKAWA NORIO
IPC: H01L21/60
Filed: 1990-05-29
Abstract: PURPOSE:To improve connecting reliability of a chip carrier to a mounting board and to reduce a manufacturing cost by forming a solder metallized layer formed on a pedestal of a mounting board in which a power source of a chip carrier is soldered only on the upper surface of the pedestal. CONSTITUTION:A pedestal 13 for connecting solder bump of a chip carrier 1 is formed on the main surface of a testing board 12 to be selectively testing the carrier 1, in the board 12, a solder metallized layer 15 is formed only on the upper surface of the pedestal 13, but not formed on its side. As a result, even if the height of the pedestal 13 due to the warpage of the lower surface of the carrier 1 (package board 2) and the warpage of the main surface of the board 12 and the height of a solder bump 11 are irregular, solder 11a can be obtained all between electrodes 10 and the pedestal 13. Accordingly, the connecting reliability of the carrier 1 to the board 12 can be improved.

Title: Fan motor drive controller
Inventor: ARAI YOSHIHIRO
IPC: H02P6/06
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To set a plurality of rotational speeds at a low cost, when the quantity of air to a fixing portion is controlled by controlling the rotational speed of a fan moor, keep the rotation of the fan motor constant, even if there is variance in the parts of the fan motor or fluctuations in power supply voltage, and use the fan motor at minimum rotational speed without considering variance in the parts of the fan motor or the fluctuation in a power supply voltage. SOLUTION: A PWM generating unit 12 generates a PWM control signal so as to PWM-control power supply voltage to a fan motor 18, and a transistor 14 changes supply voltage to the fan motor 18 to control rotational speed. A counter electromotive force detecting circuit 61 detects the actual rotational pulse from the electromotive force noise portion of the drive excitation waveform of the fan motor 18, and the supply voltage to the fan motor 18 is feedback-controlled based on the number of the actual rotational pulse detected in a fixed time interval.

Title: Automatic focusing device
Inventor: TORII REIKO
IPC: G02B7/28
Filed: 1992-05-29
Abstract: PURPOSE:To obtain an evaluated value which is tolerant to motion and a noise. CONSTITUTION:A detection part 4 which is connected behind an absolute value circuit 3 consists of a line peak circuit 4a, a mean value circuit 4b, and a peak holding circuit 4c. The line peak circuit 4a extracts maximum values SA1-SAk1, line by line, from signals (contrast component) S1,1-Sk1, and k2 outputted from the absolute value circuit 3 corresponding to the inside of a range finding frame. The mean value circuit 4b averages the maximum value SA1-SAk1 at intervals of (n) lines to obtain plural mean values SB1-SB(k1-1-n). The peak holding circuit 4c finds the maximum value SC among the mean values SB1-SB(k1-1-n) as the output of a detection part 4, i.e., the evaluated value EST. The evaluated value EST is obtained by a system which is originally similar to a V peak holding system, so the value is tolerant to the motion. Further, the averaging process of the mean value circuit 4b is interposed, so the influence of a noise upon the evaluated value EST is reducible as compared with the V peak holding system.

Title: Terminal-point arrival discriminating circuit in circular interpolation
Inventor: HORIKAWA MUNEAKI
IPC: G05B19/4103
Filed: 1981-09-04
Abstract: PURPOSE:To stop a tool securely without the need to discriminate quadrants of a terminal point, by checking the X-directional and Y-directional numbers of command pulses, and thus deciding that the tool reaches the terminal point. CONSTITUTION:A gate 6 input command pulses +x and -x from a CPU1 which outputs X-directional and Y-directional command pulses. A gate 7 outputs a signal to a terminal 8 when counters which counts said command pulses +x and -x counts command pulses as many as all X-directional command pulses. Further, gates 9 and 10 operate similarly to the gates 6 and 7 as to command pulses +y and -y. Namely, the numbers of all X-directional and Y-directional command pulses are set in the counters 7 and 10 individually. Furthermore, when the counters 7 and 10 go up to those set values, tool's arrival at a terminal point is known because the numbers of all command pulses are preset in the counters 7 and 10.

Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To realize multiple exposure photography to a frame plural numbers before and to confirm a multiply exposed image synthesizing and displaying recorded image data and image data generated by an electronic image pickup means. SOLUTION: A microprocessor 21 increases/decreases a frame number in accordance with the operation of a frame feeding button in a state where the value of a frame number N at an unexposed position is set as an upper limit. A CCD image pickup element 13 reads out the image signal of one frame and performs scanning, and the image data are fetched in an image processing circuit 16. When the frame number is <N, the circuit 16 judges it as photographing by the multiple exposure, and adds the image data H1 from the element 13 to the recorded image data H2 for every pixel so as to obtain an added value (H1+H2) equivalent to exposure at the time of performing the multiple exposure. Then, the obtained synthesized image data H3 are written in a video memory 17. A display picture simulated to the photographed result by the multiple exposure is displayed on a liquid crystal monitor 19.

Abstract: PURPOSE:To produce a liquid, light-color polyester without forming fine suspensions which adversely affect the rate of filtration, by polycondensing starting material in the presence of a highly active organotin compound and a phosphorus compound reducing agent at a specified ratio. CONSTITUTION:Starting material comprising a polybasic acid(e.g., adipic acid), a polyhydric alcohol (e.g., 1,3-butanediol) and an MW modifier (e.g., 2-ethylhexanol) is polycondensed in the presence of 70-200ppm (in terms of tin), based on the material, of an organotin compound (e.g., dibutyltin oxide) as a catalyst and 5-30ppm (in terms of phosphorus), based on the material, of a phosphorus compound (e.g., phosphorous or hyphosphorous acid) as a reducing agent. A liquid, light-color polyester can thus be produced without forming fine suspensions which adversely affect the rate of filtration, so that speed-up in a step of filtration can be achieved, and the amount of a filter aid or of an adsorbent can be reduced, which effects the improvement of yields and the reduction in the size of a filter, etc.
