Title: Measuring instrument for photo-detecting semiconductor element
Inventor: NISHIGAYA ISAO
IPC: G01J1/42
Filed: 1979-03-12
Abstract: PURPOSE: To make it possible to measure a series of bits in an image sensor, one by one, by providing a driving method and light source capable of irradiating each bit with a focusing spot independently.  
     CONSTITUTION: Image sensor 1 is placed in image sensor socket 6 and index setting switch 11 is set to the bit interval of the image sensor. Then, XYθ table 8 can rotate image sensor 1, on the optical axis of a positioning microscope and condenser 5, through the rotation of θ positioning knob 9. Since SYθ table 8 can be moved by tilting XY positioning switch 12, an operator can irradiate only bit "0" with a focusing spot by operating switch 12 over a look at image sensor 1 through microscope 5, and consequently bits "0" to "n" can be irradiated sequentially with start switch 10 ON, so that electric signals from image sensor 1 will be inputted to and recorded by a measuring instrument by way of cable 7.

Title: Transmission-type screen and its production
Inventor: NOBORIZAKA MASATOSHI
IPC: G03B21/62
Filed: 1992-02-17
Abstract: PURPOSE:To provide the screen having a wide orientation characteristic, capable of utilizing light with high efficiency, without the contrast being deteriorated by the external light and capable of being low-pitched. CONSTITUTION:An external light absorbing layer 2 is previously formed on a transparent flat plate 1 as a mask, and a distributed refractive index-type lens 4 is formed by using the mask. A low-pitched transmission-type screen having a wide orientation characteristic, high light transmittance, high diffusivity and low external light reflectance is obtained in this way. Although the surface of the screen produced by the conventional technique is easily damaged since the lens is sterically formed on the screen surface, the resistance of this screen to scuffing is enhanced because the surface is flat. In addition, since the screen need not be thinned in proportion to the pitch, a sufficiently thick screen enhanced in rigidity and easy to handle is formed by this method.

Title: Signal measuring device
Inventor: ICHIKAWA TETSUO
IPC: H01L21/66
Filed: 1994-01-31
Abstract: PURPOSE:To make measurement in approx. the same accuracy as measuring the signals to be measured immediately after calibration even in case calibration can not be done for a long period of time. CONSTITUTION:A trigger circuit 20 senses fed signals to be measured, and an A/D converter in a digital processing circuit 14 subjects the fed signals to analog/digital conversion to produce measuring data, which is stored in a memory. A calibrator circuit 30 generates calibration signal. Subsequent to the memory storing the measuring data, the calibration signal emitted by this calibrator circuit 30 is measured so that the measuring characteristic error of the measuring device concerned is determined. The error in the measuring data is calibrated by the use of this measuring characteristic error.

Abstract: PURPOSE:To attain the indication of a tracking indicating meter corresponding to the deviation of a tracking by sampling and holding the DC component of a video signal based on a control pulse signal and driving the tracking indicating meter in proportion to the peak value of the sampled by held signal. CONSTITUTION:The control pulse signal (PG pulse) inputted in a switching circuit 9, where the video signals outputted from plural rotary magnetic heads 7a and 7b are made to be one series of video signals, is differentiated in a differentiation circuit 14 and based on the output signal from the differentiation circuit 14 the video signals detected in a detection circuit 10 are sampled and held for a certain time in a sample/hold circuit 1, so that the tracking indicating meter 13 of a peak value proportional type can be driven with the output signal from the sample/hold circuit 11. Therefore, the tracking indicating meter 13 can execute the indication corresponding to the signal level of the video signal at the time of sampling. Thus, the difference of the deviation of tracking at the time of sampling can be discriminated by the difference of the indication of the tracking indicating meter 13.

Filed: 1978-03-13
Abstract: PURPOSE: To prevent tightening among cords and prevent the degradation in transmission characteristics by containing tapes which are bent to U-form or other in section between the intervening cords and containing optical fibers in the grooves thereof.

Title: Fixing method of optical parts
Inventor: NAGANUMA NORIHISA
IPC: B23K26/00
Filed: 1985-02-20
Abstract: PURPOSE:To improve the characteristic of a fixing part by projecting laser light from a metallic mechanism part side to an optical part side of a lens, etc. to melt the mechanism part and the glass surface then solidifying the same. CONSTITUTION:The lens 1 which is the optical part is disposed to a holder 2 via a space 8 and the laser light is irradiated thereon from the holder 2 side. A hole 4 is formed to the wall surface of the holder 2 and the glass is melted on the outside peripheral surface of the lens 1 by the heat of the molten metal. The metal of the holder 2 and the molten glass part of the lens 1 solidify when the irradiation of the laser light is stopped. The solidified part 5 of the metal and the solidified part 6 of the glass are directly joined along the inside surface of the hole 4. Since the solidified parts 5, 6 are formed by the laser light, the time thereof is short and no thermal strain is generated in the works 1, 2. No inclusions are made between the metal 2 and the lens 1 and therefore the characteristic of the fixing part is improved.
