Title: Focus depth extension device
Inventor: YONEYAMA TAKASHI
IPC: G02B21/36
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To provide focus depth extension device with excellent resolution and brightness at all times even when an optical condition is changed in which an image with a deep focus depth is obtained at a low cost by providing a recovery filter variable means that changes a filter coefficient of a recovery filter or a filter size or the both. SOLUTION: When a contrast arithmetic section 14 discriminates that an image signal sent from a video signal input section 13 is to be integrated, a CPU 18 transfers the image signal to an image integration section 15 to allow the section 15 to add a 1-field image sequentially and the section 15 selects a filter coefficient optimum to an optical condition such as a numerical aperture for light emission of an image forming optical system and an operating wavelength of the image pickup element from a plurality of coefficient matrix tables stored in advance so as to revise a recovery filter section 16.  Thus, the integrated image obtained by an image integration section 15 is recovered into an image focused to all parts in one field by the recovery filter section 16 and the result is displayed on a TV monitor 17, then an excellent recovery image is obtained at all times even when the optical condition is changed.

Title: Thermal printer
Inventor: TERAJIMA MINORU
IPC: B41J11/02
Filed: 1984-05-30
Abstract: PURPOSE:To make it possible to smoothly perform high speed printing even if pressure of a platen is made high, by providing a minute vibration imparting means to the platen contacted with a thermal head under pressure. CONSTITUTION:A platen 11 is formed by covering a shaft 12 with rubber 13 and minute vibration is applied to the shaft 12 of said platen 11 by an ultrasonic horn as shown by the arrow. To a platen 21 prepared by successively forming piezoelectric ceramic 23, a metal ring 22 and covering rubber 25 to the outer periphery of a metal shaft 22, high frequency voltage is applied by using the shaft 22 and the ring 24 as electrodes. Whereupon, the piezoelectric ceramic 23 is operated and minute vibration is applied to the platen 22. Because printing is performed while minute vibration is applied to the platen by a minute vibration applying means by ultrasonic vibration, piezoelectric vibration or magnetostriction vibration, rotary torque required in driving the platen may be small even if the pressure of the platen for pressing recording paper to a thermal head is made high. Therefore, high speed and high quality printing can be smoothly performed without impairing controllability by using a small drive source.

Inventor: ISHIBASHI YORIYUKI
IPC: G03F1/42
Filed: 1989-04-28
Abstract: PURPOSE:To align a reticle to a reticle alignment optical system with high accuracy by providing luminous reflection means, which reflect the light having penetrated a reticle alignment mark while sharing an optical axis and turning to the rear of the reticle alignment mark, between the reticle and a projection lens. CONSTITUTION:When the light radiated from a reticle alignment optical system 11 is irradiated on a reticle alignment mark 13, the light having penetrated the reticle alignment mark 13 is reflected by the luminous reflection means between a reticle and a projection lens 3 to irradiate a reticle alignment mark 13 from the rear. That is, the light having penetrated the reticle alignment mark 13 is reflected toward the rear of the reticle alignment mark 13 without passing through the projection lens 3. Accordingly, the reticle alignment mark 13 is simply irradiated only from the rear. Thereby, a single and sharp mark part image is reflected on a display device 30.

Title: Plane filter
Inventor: SHIRAI TADAO
IPC: H01P1/207
Filed: 1984-05-30
Abstract: PURPOSE:To produce a miniature plane filter with reduction of cost by forming a circular or rectangular through hole having its maximum diameter smaller than the size of a short side of a using waveguide to a conductor metallic plate having its thickness of <=1/10 suppressed frequency wavelength and setting a flat plate of a specific form in parallel to the electric field of the waveguide and also rectangular to a magnetic field. CONSTITUTION:A filter 1 has a circular through hole 3 having its maximum diameter less than the size (b) of a short side of a using waveguide and drilled through a conductor metallic plate having its thickness of <=1/10 suppressed frequency wavelength lambda. A flat plate having a gap 4 formed by projected parts of the plane plates set opposite to each other toward the center of the hole 3 is set in parallel to an electric field 5 of a waveguide 2 and also rectangular to a magnetic field 6. The filter 1 set to cut off the transmission line of a mode TE10 of the waveguide 2 also cuts off the magnetic fields as shown in figures (a) and (b). The inductance and the capacitive properties are increased when the filter 1 cuts off the magnetic fields 6 and 5 respectively. Then the electric power which forms equivalently the series resonance of the inductance and the capacity and passes through the filter 1 is reflected and reduced down to its minimum level through the proper adjustment of the sizes of the hole 3 and the gap 4.

Abstract: PURPOSE:To realize the automatic selection of an operating system by comparing sequentially the type signals obtained from an external connection equipment in a system rise state with those type signals held by a rise information register and transmitting a read signal to an external memory when the coincidence is obtained from said comparison. CONSTITUTION:When a system power supply is applied, a signal 201 is sent to a keyboard 4 from a rise control part 2 for production of a type signal 401. At the same time, a type information signal 601 and a system start address/ size signal 602 are read out of a rise information register 6. These signals 401 and 601 are compared with each other by a comparator 5 and a signal 501 is outputted when the coincidence is obtained between both signals. Then the control is changed so that the next information is read out of the register 6. These actions are repeated. In such a way, the signals 501 and 602 are sent to the part 2 every time the coincidence is obtained between the signals 401 and 601. Then a read control signal 202 is sent to an external memory 1 from the part 2. Thus the systems A-C are selected within the memory 1.

Title: X-ray generator
Inventor: AAMANDO PII NIYUUKAAMANSU
IPC: H01J35/12
Filed: 1984-05-30
Abstract: PURPOSE:To eliminate any concentric circular cone and alleviate the mechanical tolerance of an X-ray generator by introducing a water flow along the surface of an X-ray anode having a concave curvature going along the water flow and using a large amount of water to given cooling water a centripetal acceleration for removing bubbles evaporated near the high temperature surface of the anode. CONSTITUTION:A target is provided with a conical anode 11 having a concave curvature going along a water flow. Owing to such a wall of the rotary anode 11, the acceleration of a flow vertical to the wall is very easily separated by the phase according to the difference between the densities of the fluid and steam thereby increasing the inertia of the fluid and bumping it against the wall. As a result, light bubbles immediately after their generation are made large enough to be moved apart from the surface. Water mixes with a jet from an inlet 13, and flows expanding along the surface of the conical anode 11 at a relatively constant speed. Since the circular cone is placed in a reservoir 15 of water moving at a far slower speed, the jet gradually mixes with the water. Owing to the above constitution, any mechanical grooves do not exist around the anode 11 and the lateral mechanical tolerance is widely alleviated. An end guide 17 which is the only member existing in the water inlet 13, works to introduce the flow almost parallel to the conical surface.
