Title: Illuminating device
Inventor: IMAMICHI KAZUYUKI
IPC: G03G15/043
Filed: 1986-06-05
Abstract: PURPOSE:To uniform light distribution on the surface of an image carrier by arranging wedge-like prisms between plural light emitting elements arranged on a straight line and the image carrier so that the upper and lower gradients are mutually reversed on the border of the center part of the arraying direction of the light emitting elements. CONSTITUTION:The light emitting elements 12 are arrayed on a straight line with constant intervals to form an LED array and the wedge-like prisms 14 are also linearly arrayed. The upper and lower gradients of the prisms 14 are mutually reversed on the border of a horizontal line L passing the center part of the arraying direction of the light emitting elements 12. A light made incident upon the prism 14a is deflected to a left side and a light made incident upon the prism 14b is deflected to a right side. Thus, the rays of light emitted from the light emitting elements 12 are expanded in both right and left directions, so that the light distribution of the image carrier 5a can be uniformed as a whole.

IPC: G03F7/075
Filed: 1984-06-25
Abstract: PURPOSE:To enhance printing and scratch resistances and developing speed of a printing plate by forming a photosensitive layer and a silicone rubber layer in succession on a support, and incorporating a specified esterified novolak resin in said photosensitive layer. CONSTITUTION:The photosensitive layer of the lithographic plate formed by laminating on the support this photosensitive layer and the silicone rubber layer in this order contains the esterified compd. of the novolak resin of phenol of the formula (R is 3-30C alkyl or alkenyl, and each is substd. at the o, m, or p- position, and n is an integer of 1-3) and formaldehyde, and an o-quinonediazide compd. Such a lithographic plate requiring no dampening water is obtained by exposing it through e.g., a negative film or positive film brought into intimate contact with it by evacuation to actinic rays, and rubbing it with a developing pad contg. a developing soln. to remove the rubber layer on the image parts, and to disclose the surface of the photosensitive layer or the support serviceable as the ink receptor. Since such a printing plate is superior in flexiblity and pliability, high in printing resistance, and since this photosensitive layer is made made pliable, it is good in scratch resistance, and since it is good in affinity to a developing soln., developing speed is enhanced.

IPC: H04B1/10
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a receiving circuit whose characteristic is less deteriorated due to intermodulation of interference waves. SOLUTION: After an output signal of a MIX 5 converted into an intermediate frequency is amplified by a gain control AMP 8 so as to make the output constant, the resulting signal is detected by a quadrature detector 9, from which an I-signal 12 and a Q-signal 13 are obtained. The I-signal 12 and the Q-signal 13 are filtered respectively by LPFs 10, 11. Simultaneously the I-signal 12 and the Q-signal 13 are filtered by HPFs 18, 19, from which only a interference wave component is extracted. The I-signal 12 and the Q-signal 13 filtered by the HPFs 18, 19 are respectively A/D-converted by A/D converters 20, 21 and the level is detected by calculating the root of square sum of the I- and Q- components at a level detection circuit 22.  The signal whose level is detected is subjected to integration in terms of time by an integration circuit 23 and the level is compared with a reference level and decided by a level decision circuit 24 and its output is used to vary the gain of a low noise AMP control circuit.

Title: Variable tool-diameter type spindle apparatus
Inventor: TSUKIJI YOSHIHIRO
IPC: B23B19/02
Filed: 1982-07-27
Abstract: PURPOSE:To permit control of eccentricity angle with high accuracy by forming a spindle in a double structure, providing eccentricity between inner and outer spindles and varying the diameter of a tool by varying the relative position between said inner and outer spindles. CONSTITUTION:An inside spindle onto which a tool T is fixed is directly revolved through a driving gear fixed onto the inside spindle and an internal gear on a cylindrical body. The eccentricity angle theta between the spindle and an outside spindle is controlled by relatively revolving the spindle and the outside spindle. When the shaft core of the spindle is set at O2 and the shaft core of the outside spindle is set at O3, the center of the tool T draws a circle having a center O2 and a radius (e) by controlling the angle theta, and shifts from the shaft core O3 to T2. Thus, the working radius varies from R1 to R2.
