Title: Method and apparatus for measuring (electric) potential of sample with light probe
Inventor: GERARUTO ZERUKUNAA
IPC: H01L21/66
Filed: 1992-04-20
Abstract: PURPOSE: To obtain a method and an apparatus which can suppress a low frequency noise derived from a laser light source in an output signal of a detector unit for measuring polarization in the measurement of the potential of a sample that is made possible by the determination of the polarization of a laser probe piercing a crystal as a stray electric field developed from the sample infiltrates into the crystal to induce a double refraction when the crystal having an electrooptical characteristic is placed right above the charged sample. CONSTITUTION: A high frequency vibration is applied to a glass support TR bonded to a crystal PK to cyclically change the distance between the crystal PK and the sample PR. Output noises I(x) of a detector unit P2 and DT have a high frequency component amplitude U with limited noise.

Title: Head clash detecting system in magnetic recorder
Inventor: MATSUO NAKAHIKO
IPC: G11B21/21
Filed: 1977-10-27
Abstract: PURPOSE: To detect the contact of a magnetic head and a recording medium by detecting that the rate of variation of the period of 1 turn of the recording medium and the period of the next 1 turn following to this exceeds the intended rate of variation.  
     CONSTITUTION: A subtractor 8 is actuated by a memory clock signal MECLK 2 and a subtraction clock signal SCLK generated following to this, whereby t 1 -t 0  is obtained. This causes a divider to be actuated, by which the rate of variation between the periods t 1  and t 0  is obtained. If it is assumed that head clash has occured, then the load of the motor which rotates the recording medium increases and the rotating period thereof becomes longer, increasing the rate of variation ΔR. Hence, by beforehand setting a suitable threshold value showing a permissible rate of variation in a threshold circuit 12 and comparing this in a comparator 11, the occurrence of the head clash may be detected at an extremely early time.

Title: Method and circuit for output control of semiconductor memory device
Inventor: CHIYOU HORETSU
IPC: G11C7/10
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To obtain a stable data output by preventing the data output by a reactive address in a hyper page mode by delaying the control signal of a data-line interruption circuit by using an address transition delay signal. SOLUTION: When an ATD senses address transition, a bar ϕATS is generated. The bar ϕATS controls an I/O sense amplifier while a delay signal bar ATSD is output by a second delay circuit. On the other hand, a control signal ϕCD based on a string-address strobe signal bar CAS reaches HIGH after a fixed time when the bar ϕATS is returned from LOW to HIGH. The ϕCD and the bar ϕATSD are arithmetically operated by an AND gate 30, and a delay control signal ϕCDD is output, and added to a data-line interruption circuit 10. Accordingly, a nonconductive state is kept in the interruption circuit 10 until data by an effective address signal appear in a data line DO and a bar DO, and a stable data output is acquired.

Title: Terminal base of current transformer
Inventor: TAKAI TSUTOMU
IPC: H01F38/30
Filed: 1982-07-28
Abstract: PURPOSE:To prevent insulation breakage of a current transforming path due to changing in connection on the secondary side by a construction wherein a short-circuiting piece is provided with a cover for preventing opening of the secondary side which enables the operation of the output terminal in conjunction with insertion of a short-circuiting bolt into a terminal plate. CONSTITUTION:A short-circuiting piece 7 is provided with a cover 8 for preventing opening of the secondary side which enables operation of an output terminal in conjunction with insertion of a short-circuiting bolt 6 into a terminal plate 5. When the short-circuiting bolt 6 is inserted into the terminal plate 5, a spring 9 is deformed along a taper washer 11 and, in conjunction with this, a distal end of the cover 8 for preventing opening of the secondary side is moved upwards. When the distal end of the cover 8 for preventing opening of the secondary side is moved upwards, the cover 8 for preventing opening of the secondary side is displaced from the front of the output terminal 4 to uncover the output terminal 4, thereby permitting to loosen a screw of the output terminal 4 for necessary operations on the secondary side such as changing in connection. In this way, since the output terminal 4 can not be operated unless the short-circuiting bolt 6 is inserted to short-curcuit in the midway of the terminal plates 5 and the secondary side is brought into a closed circuit, it becomes possible to prevent insulation breakage of the current transformer 1 due to the opening of the secondary side.
