IPC: G11B7/09
Filed: 1987-06-12
Abstract: PURPOSE:To produce a tracking actuator control signal to detect dust or flaw on a track and to cope with it by splitting the frequency band of a tracking error signal. CONSTITUTION:A high pass filter 16 receives a tracking error signal as an input signal, the frequency band of the signal is split to detect only the high frequency component of the tracking error signal to form an output signal caused by the effect of dust and flaw.

Then the signal selection circuit 14 passes the signal when the output signal of the control signal generating circuit 11 is inputted. Thus, the presence of dust and flaw on the track is detected clearly and track jump, instability of the tracking servo circuit and switching noise caused by dust and flaw are avoided.

Title: Manufacture of power element employing diaphragm
Inventor: TANAKA YASUHIKO
IPC: F16J3/02
Filed: 1984-07-17
Abstract: PURPOSE:To reduce the stress within specific range by loading pressure onto the upper or lower cover while clamping a diaphragm between upper and lower covers thereby causing plastic deformation in the diaphragm. CONSTITUTION:The diaphragm 2 is provided with two lines of beads coaxially and the circumferential portion is held by the upper and lower covers 3, 4. Pressure applied onto the upper cover 3 will cause plastic deformation at the portions A and B when compared with the condition prior to application of pressure as shown by double dots and dash line. Consequently, the clearance X between the bead 2a and the lower cover 4 is reduced with the clearance Y post of application of pressure thus to substantially reduce the repeating stress at the plastically deformed portion.

Filed: 1988-06-17
Abstract: PURPOSE:To obtain an image sensor whose readout accuracy of a picture element is excellent and whose yield is good by a method wherein a line width at a crossed part of wiring parts of the image sensor according to a matrix drive system is made narrow. CONSTITUTION:In an image sensor where one set of electrodes are laminated on a substrate so as to sandwich a semiconductor layer and whose drive system is constituted in such a way that wiring parts 4a, 4b extended from the electrodes are crossed in a matrix shape, a line width of the wiring parts 4a, 4b is made narrow in parts where said wiring parts 4a, 4b are crossed. For example, the line width of electrode lines 4a1, 4a2 and signal readout lines 4b2, 4b3 is made narrow in parts where the electrode line 4a2 crossed the signal readout line 4b3. Thereby, a stray capacitance between the wiring parts is reduced; accordingly, since a frequency component in an optical signal is in a high region, a rise of the optical signal becomes sharp; in addition, since a crosstalk between adjacent picture elements becomes small, the readout accuracy of image information is enhanced.

Title: Display selection and control system for multi-item key input unit
Inventor: KONUMA TATSUROU
IPC: G06F3/02
Filed: 1977-12-12
Abstract: PURPOSE: To ensure the selection, by increasing the torque of motor, through the frequency division of the drive pulse when larger torque is required, by using the characteristics of pulse motor for page sheet selection set.  
     CONSTITUTION: The page selection switch 18 is depressed and the coded signal with the encoder 19 is fed to the comparator 21. The comparator 21 compares this signal with the signal at the position detector 14, controlling the motor drive circuit 16 and starting the motor 9, resulting in drawing out the page steet. If the movement of page sheet is slown down with friction, disagreement is caused when the number of pulses in driving the motor and the conversion value of the drive pulses for the distance between the position detection marks for every page(content of memory 26) are compared with the comparator 27. This time frequency division circuit 24 feeds the drive pulse being lower frequency to the motor drive circuit 16. Thus, when larger drive torque is required, the drive torque can be increased by frequency-dividing the pulses.
