Filed: 1985-10-30
Abstract: PURPOSE:To enhance color image recording speed, by a construction wherein the distance from a recording paper discharging point of a platen roller to a recording paper aligning means through a recording paper circulating passage is set to be larger than the length of a slip form recording paper. CONSTITUTION:A recording paper 22 and an ink ribbon 61 being in close contact with each other after recording are brought to a guide bar 82, where the ink ribbon 61 is abruptly turned, while the recording paper 22 tends to move straight ahead, and is released from the ink ribbon 61. The recording paper 22 thus released is guided by a flapper 52 into a recording paper circulating passage 33. When the leading end of the paper 22 is detected by a recording paper detector 48, a flapper 47 is closed, a solenoid 42 is energized to weaken the force of pressing a pinch roller 35 against a feeding roller 34, and the paper 22 is stopped at a point where the leading end thereof collides against the flapper 47. At this time, the trailing end of the paper 22 has come off a position where the ink ribbon 61 is separated from a platen roller 11, and recording in yellow on the paper 22 has been completed. Accordingly, since the recording paper is fed along the circulating passage to a recording part 10 each time recording in one color is completed, color recording can be performed at high speed.

Title: Production of wear resistant sliding member
Inventor: YAMAMOTO YOSHIFUMI
IPC: C21D9/30
Filed: 1989-09-21
Abstract: PURPOSE:To produce a wear resistant sliding member excellent in pitting resistance and wear resistance by subjecting the surface of a base material to remelting treatment, irradiating the surface with heat rays with high energy density into spotted state, and allowing fine cracks to occur. CONSTITUTION:The surface of a base material for forming a sliding member, such as camshaft, is subjected to remelting treatment. This remelting treatment is performed by remelting the surface layer of the above base material in this state or together with metal powder for high alloying by means of a heat energy, such as laser beam, arc heat energy, such as TIG welding, etc., to carry out hardening and forming a wear resistant alloy chilled layer. Subsequently, the base material surface on which the above alloy chilled layer is formed is irradiated with heat rays with high energy density into spotted state to undergo thermal shock. By the above thermal shock, many fine cracks are allowed to occur in the surface of the base material and residual tensile stress established due to thermal strain caused by the above remelting treatment is relieved and reduced. By this method, the wear resistance and pitting resistance of the sliding member can be improved.

Title: Electron microscope equipped with x-ray-preventing means of energy filter
Inventor: OIKAWA TETSUO
IPC: H01J37/22
Filed: 1986-10-14
Abstract: PURPOSE:To prevent a center spot from being generated by installing a lens system, in which an image of a transmitted electron beams are enlarged and projected on a record medium, a X-ray shutter which interrupts X rays, and a X-ray-preventing means of an energy filter. CONSTITUTION:Electron beams 2 emitted and accelerated from an electron gun 1 are focused by a focusing lens 3 and radiated on a sample 4, and an image of transmitted electron beams is formed by an object lens 5. Then, an orbit of the electron beams 2 is deflected into a OMEGA shape by magnetic poles 6a to 6c which compose an OMEGA-shaped energy filter. The electron beams 2 are made to avoid a shutter 7 and returned to an optical axis 12 and made to pass through a deflecting slit 13. Then, the image of electron beams is enlarged by an intermediate lens 8 and a projective lens 9 and recorded as an energy filter image on a high-sensitivity record medium 10. On the other hand, X rays 11 generated on the sample 4 have no effects of magnetic fields formed by the magnetic poles 6a to 6c and so advance along the optical axis 12 and are interrupted by the shutter 7 disposed on the optical axis 12. Subsequently the X rays 11 are not projected on the record medium 10, so that a center spot can be prevented from being generated.

Title: Stroboscopic photographing method for ccd camera
Inventor: KAWAGUCHI RYUJI
IPC: H04N5/341
Filed: 1992-09-11
Abstract: PURPOSE:To substantially decrease the virtual images generated by the smears caused by the reflection of the stroboscope exposure with no sweeping of a vertical transfer path VCCD and to improve the picture quality by emitting the light through a stroboscope right before the electric charge is transferred to the VCCD from a photodiode. CONSTITUTION:A CPU 27 supplies the signals to control a stroboscope unit 31 in regard of the quantity of light emitted by a stroboscope and the stroboscope light emitting timing. The unit 31 includes a light source 33, a stroboscope module 35 which drives the source 33, a photodiode 37 which detects the light reflected from an object, etc. Then the shift of a field is carried out right after the light emission of the stroboscope. Under such conditions, a smear image moves in a VCCD by an extent equal to a single line only. Therefore only a slight position error is caused between a real image signal and the smear image at a time point when the electric charge is shifted to the VCCD from the photodiode 37 via a transfer gate. Then both positions substantially overlap each other and therefore the smears are seldom visually recognized.

Title: Original size detector
Inventor: NAKADE TOSHIYUKI
IPC: G03G15/04
Filed: 1989-09-20
Abstract: PURPOSE:To obtain the original size detector which is small in size and is free from erroneous detection by disposing plural sensors in correspondence to original sizes in the prescribed positions of an original platen. CONSTITUTION:This device is constituted by providing the sensors 6a to 6e and 7 disposed in the state corresponding to the original sizes on the side nearer an axial line (m) than the center line of the original platen 12 along the direction orthogonal with the center line l. Detection is made by the control section receiving the sensor signals that the original size is A5, in the state in which, for example, the sensor 6a detects the original and the sensor 6b does not detect the original in this constitution. Since the sensor 7 detects the right end of the original, the control section stops a 1st moving frame 10 by the signal thereof and discriminates A3 and A4 or B4 and B5. Since the original sizes are detected in such a manner without moving the sensors along the frame 10, the need for a mechanism to move the sensors along the frame 10 is eliminated and the device is miniaturized.
