Patent JP-H01123114-A (JP)
Title: Level measuring apparatus
Inventor: YAMADA ISAO
IPC: G01F23/28
Filed: 1987-11-06
Abstract: PURPOSE:To make it possible to grasp the fluctuation of a level accurately regardless of external factors, by projecting measuring light on the surface of the level of water, which is accommodated in a tightly closed containers that are communicated to each other, and measuring the position of the surface of the water based on the receiving position of the reflected light. CONSTITUTION:A optical displacement sensor 40 is fixed together with a water level gage 30 as a unitary body and lowered with the sinking of a material to be measured. Therefore, the distance between the light emitting and receiving part of the sensor 40, which is arranged in a tank 34 so as to face the water surface, and the water surface is decreased in correspondence with the sinking amount. Light is projected to the water surface from the light emitting part. The reflected light is received and undergoes optoelectronic transducing action. The relative displacement of the water surface level is detected as the sinking amount based on the change in light receiving position. Since the sensor 40 is housed in a tightly closed container 58, the effect of atmospheric pressure on the water surface can be effectively cut out. An air pump 62, which is arranged and fixed at a side wall 54 of the container 58, blows dry air, which is supplied through a nozzle from an air feeding pipe, to the light emitting and receiving part, the lens and the like of the sensor 40. Thus steam and the like are removed, and the light is emitted and received correctly.

Title: Production of resin-coated fine particle and apparatus therefor
Inventor: HORIUCHI TAKAHIRO
IPC: C08J3/12
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To produce resin-coated fine particles in a short time by a simple apparatus and operation by vaporizing resin materials, condensing the resultant vapors on the surfaces of fine particles, and polymerizing the condensed vapors to form a resin layer on the surfaces. SOLUTION: Satd, vapors of monomers A and B are produced by causing the monomers to adhere to porous wall sections 32a of vapor-forming boxes 32 in the respective vapor supply sections 30a, 30b and heating the vapor supply sections 30a, 30b with the respective heating apparatuses 33 to bring the inside of the vapor-forming boxes 32 to a set temp. After the treating space section 41 of a mixing section 40 is adjusted to a set temp., the satd. vapors of monomers A and B and fine core particles are introduced into the mixing section 40 and are mixed in the treating space section 41. Each of the satd. vapors of monomers A and B are brought into contact with the fine core particles 1 and begin to condense around the particles 1.  The condensation is accelerated by cooling at a slow-cooling section 42, and the condensed monomers A and B polymerize to form a resin to coat the particles, thus giving the resin-coated fine particles.

Title: Graphite paste and manufacture of fluorescent character display tube using the paste
Inventor: KOBAYASHI MASAAKI
IPC: H01J9/14
Filed: 1992-10-20
Abstract: PURPOSE:To improve characteristics such as luminous brightness by using frit glass containing ZnO as a main component and the predetermined amount of Bi2O3 and graphite powder containing the predetermined amount of TiH2 and WO3. CONSTITUTION:Regarding graphite paste used for forming an anode conductor layer 4, the component of frit glass mixed with graphite is changed from a conventional PbO system to a ZnO system. That is, 0.04 to 0.77 pts.wt. of BiO2 is mixed with 1 pts.wt. of the frit glass of ZnO system. As a result, the sintering temperature of the frit glass of ZnO system drops, and the adhesive strength of a graphite layer increases even at 550 deg.C. Consequently, the separation of the graphite layer can be prevented and brightness can be improved. Furthermore, brightness characteristics can be improved by adding 0.2 to 3.0 pts.wt. of TiH2 and 0.005 to 0.1 pts.wt. of WO3 to 1 pts.wt. of graphite powder in the graphite paste using the frit glass of ZnO system.

Title: Fixed memory containing counter
Inventor: FUKUDA YASUSHI
IPC: G11C8/04
Filed: 1988-11-07
Abstract: PURPOSE:To continuously read the contiguous words with no use of an external means which increases the addresses by using a counter which selects optionally the words stored in a fixed memory and adding an address serving as the contents of the counter every time a word is read out. CONSTITUTION:The output of a counter 1 is connected to the address input of a fixed memory element 2 via a signal 13. The element 2 outputs the word contents of an address designated by the signal 13 as an output signal 14 while a read control signal 12 is kept at 0. While the signal 12 is connected to a clock terminal, and the counter 1 increases its count contents by 1 when the signal 12 rises up to 1 from 0. Then the counter 1 initializes its count contents to 0 when a reset signal 11 is kept at 0. Thus, it is possible to continuously read out the contiguous words without performing a counting action via an external means to successively increase the addresses.

Title: Active range finder
Inventor: TSURU HIROYUKI
IPC: G01C3/06
Filed: 1990-10-22
Abstract: PURPOSE:To set the maximum distance limit arbitrarily and accurately by setting it based on the signal which is output form the external adjusting device connected only on setting. CONSTITUTION:The maximum distance limit is set based on the signal output from the external adjusting device B15 connected only on setting. The combination use of the magnification level of the amplification factor corresponding to the maximum distance limit and the amplitude of the signal corresponding to the maximum distance limit being output from light receiving elements B16 and B17 allows quick and fine setting of the maximum distance limit. The set maximum distance limit is stored in a nonvolatile storage B18, and when signal processing circuits B12 and B14 set the level of amplification factor, sets so that signals, which are magnified when a range object is in a long range side early out of the signals output from the light receiving elements 16B and 17B may become proper amplification factor and sets by a signal which decreases when the range object is in the long range side later. This constitution makes it possible to arbitrarily and accurately set the maximum distance limit.

Then, the level of the corona ion current is detected and an AC voltage control circuit 7 controls the level of an AC voltage (21) for corona generation. Consequently, the stable corona ions are generated.

Abstract: PROBLEM TO BE SOLVED: To prevent an unreasonable force from being exerted to a fixing device and a raising device by providing a slip device between a ratchet wheel and a support shaft so that an automobile slips even though the automobile forcibly overrides a lock plate. SOLUTION: A rack 51 is reciprocated by an air cylinder 52 so that rotational motion is obtained by a pinion 50 meshed with the rack 51 so as to rotate a support shaft 30 which raises a lock plate 3 upright.

Abstract: PURPOSE:To enable easy, rapid, and accurate discrimination inexpensively by applying a laser beam to an edge section of a punched-out section of a lead frame and by discriminating between the right and the wrong side thereof from the difference reflected light. CONSTITUTION:A lead frame 1 after punched out is put on a transportation belt 5 to be transported to a specified position. A photoelectric switch 6 which can irradiate a laser beam to the lead frame 1 under transportation is provided with a photoprojecting section 7 and a photosensitive section 8 of the laser beam. Laser beam is successively irradiated from the photoprojecting section 7 of the photoelectric switch 6 to an edge section 4 of a punched-out section 3 which is used as a feed hole. Here, if the edge section 4 is the right side, reflected light is injected to the photosensitive section 8, and if it is the wrong side, the photosensitive section 8 can not receive incident light because of irregular reflection. Therefore, it is possible to discriminate the right and the wrong side of a lead frame from whether or not incident light is directed to the photosensitive section 8. Operation can be thereby carried out readily, accurately, rapidly and inexpensively.
