Title: Method for refining copper ultra fine powder
Inventor: KOUNO YUMIKO
IPC: B22F1/00
Filed: 1988-06-29
Abstract: PURPOSE:To remove CuCl in ultra fine powdery Cu and to produce the Cu ultra fine powder having high purity by heating the ultra fine powdery Cu produced by gas phase hydrogen reduction to CuCl, in vacuum under containing the specific quantity of O2, because CuCl is remained as impurity in the Cu powder. CONSTITUTION:In the ultra powdery Cu obtd. by the gas-phase-reducing CuCl with the hydrogen gas, CuCl is contained as the impurity at a little. O2 content in the Cu ultra fine powder is held to <=0.5wt.% and the powder is laid on a pot 3 in a vacuum vessel 1. After reducing the pressure in the vacuum vessel 1 into Ar atmosphere having <=1Torr with a vacuum pump 6, the vessel 1 is heated at 300-350 deg.C with an electric furnace 2 around the vessel 1 and the remained CuCl in the Cu ultra fine powder is volatilized, removed and refined. As O2 in the Cu powder as the raw material is contained to <=0.5%, the Cu powder is refined into the ultra fine powder state without sintering and making coarse grain of the Cu powder at the time of heat treatment.

Title: Electrostatic recorder
Inventor: EZAKI TAKASHI
IPC: B41J2/41
Filed: 1978-12-26
Abstract: PURPOSE:To achieve the improvement in resolution by using the recording layer comprising disposing photoconductive materials on a conductive material at picture element spacings and coating dielectric material thereon, and letting the charges between the picture elements of latent images be erased through radiation of light. CONSTITUTION:A recording medium is constituted by forming photoconductors 7 on a conductor 6 and coating dielectric 5 thereon. The photoconductors 7 are so disposed as to oppose to the insulator portions 2 between the electrodes 1 and 1 of the recording head. With such constitution, the latent image dots are formed by having negative charges on the dielectric 5 with the spreading wider than the electrdes 1. Thereupon, when light is radiated, the photoconductors 7 assume conductivity, due to which part of the negative charges lose from the photoconductors 7 to conductor 6. Hence, the size of the latent image dots may be made nearly the same or lower than the diameter of the recording electrode 1, and the resolution of the recorded images may be enhanced.

Title: Optical magnetic memory
Inventor: TSUKADA MASAHARU
IPC: G11B11/105
Filed: 1988-06-29
Abstract: PURPOSE:To decrease a reproduced error rate by providing a means to execute an erasing operation to a non-recording part, and applying a function to align the direction of the magnetization of the non-recording part. CONSTITUTION:First, a controller 6 decides whether or not a changeover switch 7 is closed. When the switch 7 is decided to be closed, next, an electromagnet 3 is driven so as to generate an erasing magnetic field. When an AT polarity switching signal is sent to the change-over switch 7 inside the controller 6, a laser beam spot radiated on a land 21 is shifted to a group 20. Continuously, the beam spot shifting is suitably executed. After group tracking is made OK, the operation to set laser power at erasing power is executed, thereafter, the group erasing is executed while group tracking is being executed. Thus, even when the optical beam spot is partially stuck to the non-recording part at the time of reproduction, it does not cause the noise mixture to the regenerative signal, and the reproduced error rate can be drastically decreased.

Title: Sensor head device
Inventor: AOYAMA SHIGERU
IPC: G01B11/00
Filed: 1988-06-29
Abstract: PURPOSE:To improve the measuring accuracy by providing at least one of a light source and a photodetector outside a sensor head and transmitting at least one of an emitted light and a received image by an optical fiber. CONSTITUTION:A controller 1 and a sensor head 6 are connected each other by an optical fiber 4 and a bundle optical fiber 5. The controller 1 is provided with a semiconductor laser 2 as a light source and a photodetector 3. The light emitted from the laser 2 is sent to the head 6 via the optical fiber 4. Then, the light is projected out of the head 6 through a microlens array 7. This projected light is, after it is condensed by each microlens, dispersed and accordingly diffracted. Therefore, many spots are formed far at a distant place by the diffracted light. The projected light from the head 6 is radiated to an object 15 to be detected, and the reflected light is received by the photodetector 3 through the objective lens in the head 6 and the optical fiber 5. Thus, if the coordinates of the position on the element 3 are detected, the position coordinates of the object 15 can be obtained.

Abstract: PURPOSE:To deal with a non-interlace signal as an input by making two field memories corresponding to a polarity of the field of a master screen to be read and writing alternately in the two field memories in the slave field cycle in writing so as not to make the relation with the reading inconvenient. CONSTITUTION:On reading field memories 2, 3, the field memory corresponding to a field polarity of a master is read. While, a writing in either one of the field memories 2, 3 is basically determined by a binarization signal altenately changing over by a slave vertical synchronous signal. Namely, even when a non-interlace signal enters, an inconvenience such as the signal being written only in one field memory cannot be produced. A countermeasure of 'a passing condition' is also required and in the circuit, D flip-flops 12, 13, a switch 14 and an AND gate perform its function.

Abstract: PURPOSE:To instantaneously execute a time necessary for density conversion by providing a signal converting means and executing a signal conversion so as to make the low-order bit data of an address signal to execute the address designation of a memory into all the same. CONSTITUTION:To respective least significant bits of a horizontal address signal line and a vertical address signal line inside an image memory address control circuit 15, AND circuits 150 and 151, switches 153 and 154 and resistances 155 and 156 are provided. When the switches 153 and 154 are connected to a grounding side, the AND circuit is made inactive, and the signal at '0' level is always sent. For such a reason, as the address signal, a picture element to be adjoining is selected every time the level of the least significant bit is changed. For such a reason, by always making the least significant bit into the '0' bit, the selection of the picture element is executed by the high- order bit, and the picture element is selected every other one. Consequently, the processing time is made much faster than a software.

When an output signal from a comparator 22 is turned to the high level, a Tr4 in an alarm device 23 is turned on, a light emitting diode LED is emitted in the finder to generate an alarm. Thus, misphotographing is removed at the use of the strobe 2.
