Title: Thinning processing device in image processing system
Inventor: ADACHI TSUNEO
IPC: G06T5/30
Filed: 1990-03-28
Abstract: PURPOSE:To execute window processing by utilizing neighbourhood information stored in a neighbourhood information memory for executing thinning processing. CONSTITUTION:At the time of starting the thinning processing, the information of a picture element neighboring upon a remarked picture element is read out from the neighbourhood information memory 2 and inputted to a deciding processing means 4 and the binary data of the remarked picture element are inputted from a binary data of the remarked picture element are inputted from a binary data of the remarked picture element are inputted from a binary image memory 1 to the means 4. When the inputted heighbourhood information coincides with a deletion pattern stored in the means itself 4 and the binary data of the remarked picture element is '1', the means 4 decides the deletion of the binary data of the remarked picture element and rewrites the data of the remarked picture element concerned stored in the memory 1 to '0'. After the end of processing of the means 4, a neighbourhood information forming means 5 forms new neighbourhood information based upon the undated binary data and writes the formed information in the memory 2.

Title: Electrochromic element
Inventor: MATSUHIRO KENJI
IPC: G02F1/155
Filed: 1980-06-10
Abstract: PURPOSE:To improve display quality and contrast and prolong a life by providing the 3rd electrode consisting of a mixture of graphite and MnO2 other than display electrodes and a counter electrode to an electrochromic (EC) element. CONSTITUTION:A counter electrode formed with an EC material 6 on an electrode 5, and separately the 3rd electrode 11 made by mixing 20-70wt% MnO2 to expanded graphite and molding the mixture by pressing are formed on a counter electrode substrate 4 of the EC elements. Since expanded graphite is used for the electrode 11, it can be molded without using any binder and therefore this electrode does not release impurity ions into electrolyte 8. In addition, the quantity of electricity that can be utilized with respect to volume is large. This element provides good contrast by first making the electrode 11 positive and the counter electrode negative to color the EC material 6 then shortcircuiting the electrode 2 and the counter electrode to keep them at the same potential and coloring the EC material 3 on the electrode 3 dark. If the display electrode 2 is made positive and the counter electrode 5 negative, the display is quickly erased. When the contrast has lowered upon repetition of coloring and decoloring, the electrode 11 is made positive and the counter electrode 5 negative, whereby the original good contrast state is recovered.

Title: Manufacture of optical waveguide device
Inventor: HAKOGI HIRONAO
IPC: G02B6/13
Filed: 1991-03-18
Abstract: PURPOSE:To make damages and defects due to discharge during manufacturing process less likely to occur and shorten heating and cooling time of a substrate when the temperature of the substrate changes by supplying ionized gas around the substrate. CONSTITUTION:An inert gas is used as the ionized gas to be supplied into a vacuum deposition chamber 4 from an ionized gas supplying unit 8. Prior to the vacuum deposition, the deposition chamber 4 is evacuated. When a substrate 2 is heated, ionized gas is supplied in the vicinity of the substrate 2. The supply of the ionized gas is stopped when the temperature of the substrate 2 becomes constant. A film is deposited on the surface of the substrate 2 by evaporating a deposition material 12 by means of an electron gun 14. Ionized gas is supplied later around the substrate 2 when the substrate 2 is cooled down to the room temperature. This prevents electric discharge which otherwise occurs on the surface of the substrate 2 when it is heated and cooled.

Filed: 1990-03-26
Abstract: PURPOSE:To compose the zoom lens of a small number of lenses and to make the lens low in cost and compact by composing the front group of a lens which has positive refracting power and a lens which has negative refracting power in order from the object side and the rear group of a lens which has negative refracting power or no refracting power and a lens which has negative refracting power.

Further, the rear group consists of two negative lenses to prevent the Petzval's sum from decreasing positively and also prevent the image plane from slanting into an under state. Consequently, while optical performance is maintained, the low-cost, compact zoom lens consisting of a small number of lenses is realized.

Title: Pipe heater having protective cover
Inventor: OGURA MASAHIKO
IPC: H05B3/40
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent a pipe heater from being damaged by avoiding the receiving directly of thermal shocks or drop impacts by covering the pipe heater with a metal protective cover. SOLUTION: This pipe heater is composed by covering a cylindrical pipe heater 11 with a protective cover 12 which has a thickness not more than 0.3 mm and is formed by shaping soft aluminum into a pipe having a regular octagon shape in its cross section perpendicular to the lengthwise direction in a manner for forming a space between the cylindrical pipe heater 11 and the cover. The damage of the quartz tube of an armoring sleeve that is low in mechanical strength is prevented by colliding the corner part of the protective cover 12 first with another thing and moderating the impact by deforming it, when the pipe heater is dropped by mistake. In addition, when water drops are attached to it at high temperatures, a thermal shock will not be imposed directly on the quartz tube, so that a crack can be prevented from occurring.  Still additionally, because the protective cover 12 is made on aluminum and thereby has high thermal conductivity, the temperature distribution of its surface can be equalized, and the thermal conduction efficiency to a water supplying pipe can be improved. A polygonal pipe can be also used for the cross-sectional shape of the protective cover, without restricting it to a regular octagon.

Title: Cooling device
Inventor: INOUE JOJI
IPC: F25B9/00
Filed: 1990-03-26
Abstract: PURPOSE:To maintain a sufficient cooling effect of a cooling device even if it is used at a high altitude in a low atmospheric pressure environment when moving at very fast speed by providing a diffuser which decompresses air flowing at high speed, a middle cooling section which is connected the diffuser and designed to cool compressed air, and a nozzle section which insulates and expands the air brought into contact with the middle cooling section. CONSTITUTION:The air which flows into a cooling device, flows into a diffuser 1 where its velocity is smoothly reduces and its kinematic energy is converted into pressure and temperature energies so that it may turn into high temperature and high pressure air. This high temperature and high pressure air flows into a middle cooler 2 where it turns into a medium temperature and high pressure air. This air flows into a nozzle 3 where its pressure energy is converted into kinematic energy. The insulation expansion resultant from the pressure drop at that time turns the air into low temperature and low pressure air. The low temperature and low pressure air flows into a section 4 to be cooled where cooling operation takes place and the cooled air is discharged outside into the open air. Therefore, it is possible to obtain sufficient cooling effect even when this cooling device is used for a transportation which moves at very high speed and even if it is in a low air pressure environment at a high altitude.
