Title: Absorbing body of solar energy
Inventor: DOI HIROSHI
IPC: F24J2/48
Filed: 1980-09-22
Abstract: PURPOSE: To decrease the heat loss caused by the radiation from an absorber surface by treating the surface of a copper or a copper alloy base material with an alkali solution containing a persulfuric acid or its salt, said solution being subjected to a means of activation.  
     CONSTITUTION: In an absorber which absorbs a solar energy and trasforms it into heat, the surface of its base material made of a metallic copper or its copper alloy is treated with an alkali solution containing a persulfuric acid or its salt, said solution being subjected to an activated means. As an activated means, such means as an irradiation of an ultraviolet ray, an irradiation of a supersonic, or an addition of an oxidation agent is adopted. As the oxidizer, a potassium chromate or the like is employed. With this, electromagnetic wave which occupies the larger part of the wave length rangein solar energy can be absorbed effectively, thereby being possible to decrease the heat loss caused by the radiation from the absorber surface.

Title: Camera control method for video telephone
Inventor: SANO SHOICHI
IPC: H04N7/14
Filed: 1988-05-30
Abstract: PURPOSE:To shallow the depth of field of a camera by deciding a distance to a transmitter-receiver from the feed quantity of a transmitter-receiver cord which has been measured by a feed quantity measuring instrument, and adjusting a focus of the camera to an operator by a camera controller. CONSTITUTION:When an operator 6 moves forward and backward, a transmitter-receiver cord 1 is fed out of a cord feed quantity measuring instrument 2 or wound up. On a spool 22, a hole for allowing a light beam to pass through is pierced, and by detecting the number of times of a light beam passing through this hole by an optical rotation detector 21, the feed quantity of the transmitter-receiver cord 1 is measured. In such a way, a moving amount for moving a focus of a camera 3 forward or backward is calculated. According to such a constitution, the depth of field of the camera 3 can be shallowed, and it is unnecessary to shorten the focal distance so much, therefore, an image becomes bright and a distortion is scarcely generated, and also, an unnecessary object being behind the operator 6 comes not to be reflected clearly.

Title: Surface light source device
Inventor: MATSUMOTO HIRONORI
IPC: F21V8/00
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an even surface light source without causing illumination spots and glare by forming one side end of a light guide plate for making the light outgo from a surface thereof with an isosceles triangle columnar part having a specified bottom side length, and positioning a light source in a back surface of the light guide plate so that a light emitting surface faces to the bottom side of the light guide plate. SOLUTION: Electronic parts 3 and a light source 4 having a semiconductor light emitting element are mounted on a board 2, and a light guide plate 5 and a case 6 are installed thereon. One side end surface of the light guide plate 5 is integrally formed with an isosceles triangle columnar part 5A having a bottom side nearly twice of the thickness thereof so that a nearly half of the surface of the bottom side leads the light from the light source 4. The light emitting surface of the light 4 is housed in the case 6 under the condition where it faces to an incident surface part 5a of the light guide plate 5. With this structure, the light from the incident surface part 5a is reflected by an inclined side part 5b, and furthermore, reflected by an inclined side part 5c so as to be led to a surface part 5e, and scattered by the irregularity of the surface part 5e for outgoing.  The light reflected into the light guide plate 5 by the surface part 5e is reflected by the irregularity of a back surface part 5f so as to outgo from the surface part 5e.

Title: Control system for data base storage region
Inventor: KIKUCHI RIYOUICHI
IPC: G06F7/00
Filed: 1977-11-02
Abstract: PURPOSE:To increase the process speed greatly by providing the data base control system and storing the record which received the storage request from the application program with decision of the next record strorage position. CONSTITUTION:Data base control system 2 controls and executes by itself the record storage process to data base 5. In other words, in case application program PGR1 stores a certain record, PGR1 has only to give the write order after designation of the types of record. As for the personel control work, for example, the record storage of a certain person suffices with indication that it is an individual record belonging to department A and with emission of the write order. When PGR1 gives the record storage request to system 2, system 2 decides the optimum storage position via region control function 4 and by referring to data dictionary and directory DD/D6. Then system 2 performs storage to base 5 based on the decided next storage position.

Title: Printing driving system for dot printer
Inventor: SASAKI TAKASHI
IPC: H01F7/14
Filed: 1979-10-13
Abstract: PURPOSE:To prevent the print from being made thin due to the mutual interference between electromagnetic coils being arranged closely, by a method wherein small amounts of current are supplied to the nondriving coils which are adjacent to the driving coil, in the adjacently arranged electromagnetic coils of the dot printer. CONSTITUTION:In the case where a current is supplied to the electromagnetic coil M2 of the impact type dot printer in order to drive the printing operation, the magnetic flux generated at the coil M2 leaks to the adjacent electromagnetic coils M1 and M3, thereby weakening the magnetic force of the coil M2 and resulting in an unclear print. To avoid this problem, small amounts of current which do not drive the dot pins are supplied to the coils M1 and M2 to generate weak magnetic fluxes, which make the magnetic flux of the coil M2 more repulsive. Accordingly, when a printing signal is impressed on a terminal b, a coil 9b is driven and the current weakened by the resistance flows also into the adjacent electromangnetic coils 9a, 9c through diodes. In addition, since the reduction in the magnetic force of the coil can be prevented, the printing speed is enhanced and the printer is miniaturized.
