Title: Serial communication system for a/d converter
Inventor: HIGASHIDA HIROBUMI
IPC: G06F3/05
Filed: 1988-01-07
Abstract: PURPOSE:To avoid reception of the undesired A/D conversion data by sending the permitting and inhibiting instructions to an A/D converter from a processor for the A/D conversion. CONSTITUTION:The permission/inhibition of the A/D conversion is controlled at the level of a terminal A of a processor 2. The level of the terminal A is switched between H (high) and L (low) levels by a program of the processor 2. Thus the terminal A is set at an L level (output of a permitting instruction) right before transmission of the request channel data and then at an H level (output of an inhibiting instruction) right after reception of the A/D conversion data respectively. Thus no A/D conversion is carried out even though the noise is put on the line of a request channel with the terminal A set at an H level and turned into a start signal since an A/D converter 1 is not activated. Then it is possible to prevent such a harmful process where the data are broken in a RAM 21 after the undesired A/D conversion data is received by the processor 2.

Abstract: PROBLEM TO BE SOLVED: To lower the loss of the energy flowing in a signal line by providing a gap and a control line connected to an electrode arranged with a space from each signal line, and arranging the control line and a control terminal with a more space from the signal line in comparison with an electrode position. SOLUTION: Signal lines 2a, 2b for flowing the high frequency electromagnetic energy are separated from each other by a gap G. A lower electrode 11 is formed with a distance D1 from the gap G and the signal lines 2a, 2b. One end of a control line 16a is connected to a side surface of the signal line 2a side of the lower electrode 11. The control line 16a is obliquely extended from the lower electrode 11 in a direction for separating from the signal line 2a. Consequently, a distance between the control line 16a, the control terminal 3a and the signal line 2a are larger than the distance D1.

Title: Position limiting system for underwater target
Inventor: HAYASHI YOSHIO
IPC: G01S5/22
Filed: 1990-01-08
Abstract: PURPOSE:To limit the position of the underwater target by shifting plural specified frequencies from two acoustic sensors to a base band and performing signal waveform correlation arithmetic while sliding the time corresponding to an extracted feature frequency. CONSTITUTION:A narrow-band signal generator 11 shifts the frequency to the base band of a low frequency range with a time-series signal specified by an operator as a feature frequency 110 and stores it in a narrow-band signal memory. Waveform correlation computing elements 14-1 - 14-n performs waveform correlation arithmetic among read data of the narrow-band signal memory and supplies the correlation value output 120 to a correlation value adder 15. The correlation value adder 15 adds correlation values obtained by base-band narrow signals 111 to find the time position of the maximum correlation value. A maximum correlation value-time difference detector 16 finds the maximum correlation value among acoustic sensor outputs and limit the position according to the received signal time difference.

Title: Tool holding mechanism for bonder
Inventor: SUZUKI YASUNOBU
IPC: H01L21/60
Filed: 1987-01-08
Abstract: PURPOSE:To eliminate the need for adjustment only by setting up a tool to a tool holder by installing a second leaf spring, oppositely faced both ends of which are fixed to a mounting and the oppositely faced both ends of which under a free state are fastened at oppositely faced both ends under the free state of a first leaf spring. CONSTITUTION:Both ends in the X direction of a first leaf spring 5 are fixed to a tool holder 2, and both ends in the X direction of a second leaf spring 11 are fastened to a mounting 10. Since both ends under a free state in the Y direction of the first leaf spring 5 and both ends under the free state in the Y direction of the second leaf spring 11 are fastened, both ends in the X direction of the first leaf spring 5 can be deflected vertically to the second leaf spring 11, the mounting 10, and both ends in the Y direction of the second leaf spring 11 can be deflected vertically to the mounting 10. Accordingly, a tool 1 can be deflected in the arbitrary direction, thus enabling the lower surface of the tool 1 to follow the arbitral inclination of a bonding surface at all times.
