Title: Video camera
Inventor: FUMOTO KAZUHIRO
IPC: G02B7/28
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent an automatic focusing device from being focused with a water droplet, etc., stuck on the lens protection glass surface of a protection case by limiting the closer end of a moving range for the focus lens of the automatic focusing device when performing photographing while putting a video camera in the protection case. SOLUTION: A differentiation circuit 4 detects the polarity of a change in a focus voltage at the time of moving the position of a focus lens 15 between C and I and in the case of a negative value, motor driving circuits 8 and 9 are controlled so as to move the focus lens 15 to the closer side but in the case of a positive value, those circuits are controlled so as to move the focus lens 15 to the infinite side. As a result, focusing is aligned with the position having the maximum value of the focus voltage. Namely, since the focus voltage is made maximum at a position D from the position C to the infinite end I, the focus lens 15 is moved to the position D, and an object intended by a photographing person can be focused. The automatic focusing device can be prevented from being focused with the water droplet, etc., stuck on the lens protection glass surface of that protection case.

Title: Apparatus for generating low temperature air
Inventor: TORAI YASUSHI
IPC: F25D23/00
Filed: 1988-07-28
Abstract: PURPOSE:To improve a heat exchanging efficiency and reduce an energizing electric current by a method wherein air is cooled by a first evaporator, the air is cooled by a second evaporator to a value less than an icing temperature and at the same time each of air flows within both evaporators is applied as a down-flow and an upper flow, respectively. CONSTITUTION:As air enters a first evaporator 1, the air is cooled down to about 2 deg.C and thereafter as the air enters a second evaporator 2, the air is further cooled down to about -30 deg.C. Since the air is cooled and dehumidified by the first evaporator 1, an amount of moisture contained in air entering the second evaporator 2 becomes less than a specified value, resulting in that an amount of ice adhered to a surface also becomes less than a specified value. The air sent from an air blower may enter the first evaporator 1 to make the moisture content down-flow so as to make a positive flow to a lower drain pan 3, and at the second evaporator 2, it is made as an upward flow so as to prevent the grown ice and frost from being dispersed out. A lower part of the second evaporator 2 is made as a net 29 so as to increase an amount of accumulation of ice and frost and then the evaporator 2 is prevented from being clogged at its upper part so as to keep a cooling performance.

Title: On-line delayed processing system
Inventor: TAKAHASHI KEIKO
IPC: G06F11/00
Filed: 1989-07-21
Abstract: PURPOSE:To restore data via a terminal journal file at occurrence of a fault by updating the terminal journal file concurrently with transmission of data to a host computer. CONSTITUTION:A host computer 5 uses the conversation programs 6 and 7 to the terminals 1 and 2 and a memory 9 in an area where data are transferred between an update file 11 and an update program 10. The terminals 1 and 2 contain the terminal journals 3 and 4 and update both files 3 and 4 in a transmission/reception mode to the computer 5. When a fault is produced and restored, the control information on the files 3 and 4 are compared with the control information on a host journal file of the computer 5. If no coincidence is obtained between both information, the corresponding data are continuously taken out of the files 3 and 4 until the coincidence is secured. Then these data are sent to the transfer area 9 via a fault restoring means. As a result, the terminal response time and the delayed processing time are shortened. Then the data smoothly is restored at occurrence of a fault.

Title: Expanding and contracting method of dot pattern
Inventor: OOTA SHIGEKI
IPC: G09G5/36
Filed: 1983-10-11
Abstract: PURPOSE:To obtain an expanded/contracted pattern with an optional value by finding out the inversion transient points and fringing points of dots and expanding/contracting vector values obtained from these points to obtain the dot pattern. CONSTITUTION:Vertical and horizontal directions are scanned to extract the inversion transient points of dots and the extracted values are stored in respective direction buffers. Data in the respective direction buffers are matched with a start point and extracted successively and the OR operation of these data is executed, so that the fringing point is found out and stored in a fringing buffer. A pattern formed by the fringing lines can be completed by connecting respective fringing points. While shifting the horizontal scanning also to the vertical scanning from the position considered as the most outer side of a new pattern, a point S (a, b) is determined. A line coinciding with the fringing line of the pattern when observed from the point S is the 1st vector and a line coinciding with the fringing line at the leading end is the 2nd vector. These vector data are expanded/contracted. While comparing the obtained pattern with an original pattern, the inside and outside of the area surrounded by the vectors are determined and the inside is painted out and the painted-out range is filled with dots to form a new pattern.

Abstract: PURPOSE:To efficiently agitate highly viscous liquid by providing a vertical revolving shaft in the center part of a vessel, laterally protruding agitating blades from said shaft, and providing a cylindrical ring surrounding the vertical shaft with a certain distance between just above or just under the agitating blades. CONSTITUTION:The agitating device consists of the vertical revolving shaft 2 provided in the center part of a treating vessel 1, agitating blades 3 protruding laterally from the shaft, and the cylindrical ring 4 fixed just above or just under the agitating blades 3. When the cylindrical ring 4 is fixed just above the agitating blades 3 and the vertical shaft is revolved in the direction shown by the arrow, the liquid is sent to the outside as shown by A due to the rotation of the blades 3 and is decompressed there, and the liquid in the upper part is drawn to the decompressed part. As a result, the liquid flow streaming to downward from the upper part in the cylindrical ring is generated as shown by C, and the convection which streams downward in the center part and upward in the peripheral part is generated in the treating vessel. Thus, as the viscous liquid is always circulated and agitated, a preferable agitation is carried out without sticking in a solid state to the wall surface of the vessel and the agitating blades, etc.

Abstract: PURPOSE:To reduce the danger of ignition at the mixing time of a catalyst and a solvent, by preliminarily adding a small amount of water to the catalyst to wet the same and adding a water-soluble org. solvent to the wetted catalyst to mix and disperse the solvent. CONSTITUTION:After water is preliminarily added to a catalyst to wet the same, a water-soluble org. solvent is added to and mixed with the wetted catalyst to obtain a dispersion. For example, 100-200g of water containing 0.5-5% of a surfactant is added to and mixed with 100g of a carbon powder (catalyst) supporting fine particles of platinum in a ratio of 10%. Next, 300-700g of ethylene glycol is added to the dispersion to be quickly and uniformly mixed therewith and subsequently dispersed by a roll mill dispersing machine to obtain an ethylene glycol dispersed paste of a platinum/carbon powder. By this method, the danger of ignition can be reduced to 1/3-1/5.

Inventor: MATSUI MASAMI
IPC: A01D34/83
Filed: 1990-07-17
Abstract: PURPOSE:To uniformly use blade parts at both edge parts of endless belt type reaping blade and to improve durability by winding the endless belt type reaping blade formed in Mobius' ring shape around a driving pulley and a driven pulley. CONSTITUTION:An endless belt type reaping blade 3 formed in Mobius' ring shape is wound around a driving pulley 1 and a driven pulley 2. The driving pulley 1 and the driven pulley 2 are rotated, the endless belt type reaping blade 3 is transferred and weeds, etc., are reaped away. In the operation, since the endless belt type reaping blade 3 is formed in Mobius' ring shape, the endless belt type reaping blade is transferred while both end parts of the endless belt type reaping blade 3 change longitudinal position at every other lap based on the direction of the center. Consequently, length of acting edge parts becomes twice the peripheral length of the endless belt type reaping blade 3 and both the edge parts are equally worn by operation in the same working direction so that the life of the endless belt type reaping blade 3 can be prolonged approximately twice.
