Title: Character recognizing system
Inventor: TSUKUMO ATSUSHI
IPC: G06K9/42
Filed: 1990-04-19
Abstract: PURPOSE:To improve the character recognizing ability by providing a feature extracting means and a sorting/identifying means which performs the calculation to decide a standard for the falseness between a 2nd feature pattern and each reference pattern of a 2nd recognition dictionary, decides a standard for the similarity among all character types, and decides and outputs the recognition result. CONSTITUTION:A sorting/identifying means 7 reads the 1st and 2nd feature pattern signals 14 and 15 out of a feature extracting means 4, a 1st reference pattern signal 16 out of a 1st recognition dictionary 5, and a 2nd reference pattern signal 17 out of a 2nd recognition dictionary 6 respectively. Then the means 7 performs the collating calculation to decide a standard for the similarity between a 1st feature pattern and each 1st reference pattern and then the collating calculation to decide a standard for the similarity between a 2nd feature pattern and each 2nd reference pattern. Thus a standard is obtained for the similarity among all character types, and the recognition result is decided and a signal 18 is outputted. As a result, the effect of the nonlinear normalization is utilized and the high recognizing performance is secured even when a sentence including the handwritten KANJI (Chinese character) and non-KANJI.

Title: Semiconductor device
Inventor: KITANO MAKOTO
IPC: H01L23/50
Filed: 1995-04-26
Abstract: PURPOSE:To prevent a reflow crack caused by a vapor pressure by a method wherein a through hole having a special shape is formed in a tab, a resin part is restricted to the tab by the hole and a stress which is generated in a corner part, on the rear surface of the tab, in which the reflow crack is caused is reduced. CONSTITUTION:Both ends of a tab 1 are supported and suspended by tab suspension leads, and a through hole 2 is formed nearly in the center. The through hole 2 is spread gradually to the direction of an element 4, and a side opposite to the element of becomes gradually narrow. The part of an area which is smaller than an area on a face opposite to a face on which the element is mounted of the through hole 2 is formed at the inside of the through hole 2. As a result, steam 6 is generated at the interface between the tab 1 and the resin part 5, the resin part 5 swells due to its pressure, and a stress is generated in the resin part 5 at a corner part on the rear surface of the tab. However, since the through hole 2 in the tab 1 restricts the resin part 5, a size (a) can be reduced to 1/2 or lower as generated stress can be reduced to 1/4 or lower, and a reflow crack can be prevented.

IPC: H04L27/227
Filed: 1984-05-21
Abstract: PURPOSE:To reduce the time required for eliminating phase uncertainty by detecting a repulling-in phase in a specific order at all times from a present phase state when a pulling-in phase is transited due to phase slip in a 4-phase PSK demodulator. CONSTITUTION:A signal selecting circuit 7 an output SC of an exclusive OR circuit 5, its inverting output, the 2nd output SB of a control signal generating circuit 1 and its inverting output with an output SD of an initial state detecting circuit 8 to output signals SE, SF. The 2nd output SF of the signal selection circuit 7 and the 1st data input P are inputted to an exclusive OR circuit 2 and the 1st output SE of the signal selection circuit 7 controls a signal replacing circuit 4. If a phase slit takes place, the phase of a reproduced carrier has the highest probability in transiting to an adjacent phase rotated by pi/2 and 3/2pi. Through the use of the characteristic, the time for repulling-in is reduced by detecting the repulling-in phase when the pulling-in phase is transited due to phase slip in the order of pi/2, 3/2pi and pi at all times.

Title: Production of colored aluminum product
Inventor: MURAKAMI HIROMICHI
IPC: C25D11/18
Filed: 1980-07-24
Abstract: PURPOSE: To prevent the discoloration of a paint film owing to desorption of the electrodeposited paint film of adsorbed metal and the characteristic change of a paint bath by painting by electrodepositing a colored Al material adsorbed with metal on an oxide film of an Al material by forming cathode charge holding complex of adsorbed metal.  
     CONSTITUTION: An Al material through anodic-oxidation and coloring treatment processes is treated with a treating liquid after washing, thence it undergoes rinsing and/or hot washing process, and is subjected to electrodeposition painting then further to washing and setting followed by baking, whereby it is made into a product. This treating liquid is a treating agent soln. of thiosulfate, carboxylic acids such as citric acid and oxalic acid, and their salts forming complex having cathode charge by being coordinated into metals to be adsorbed such as Ag, Cu and Co. Although the treating agents have no limits, H +  is formed by electrolysis of water near the surface of the colored Al material and therefore those which are acidic and form stable complex are particularly high in treatment effect. The treating agents are usually used in the form of an aqueous soln. and may be used after the above-described hot washing process or in electrodeposition paint liquid.

Title: Digital voting device and method for multi-sight-public-service rf trunking-system
Inventor: TOOMASU ARUFURETSUDO BURAUN
IPC: H04M11/00
Filed: 1990-04-18
Abstract: PURPOSE: To minimize the delay of a device by discarding all other messages received by other receiving means within a determined redundancy removing period. CONSTITUTION: A service request type transmission link (FSL) connects plural digital receivers to be allowed to compete with each other at the time of using a series data line (BSL). At the time of receiving a message to be transferred to a digital selector 102, a digital receiver 104 latches the state of a synchronizing line (FSL) 108. When the FSL 108 is active, the receiver 104 regards its own message as a redundant one and occupies the FSL 108 by changing the state of the FSL 108 to immediately discard the message. The receiver 104 occupying the FSL 108 holds the FSL 108 at a low active level for a current period, and in a period for removing the redundant message, other digital receivers 104 for receiving the message simply discard the message. Consequently the delay of the device can be minimized.

Title: Air-conditioning system using natural air current
Inventor: TANAKA HIROKUNI
IPC: F24F3/00
Filed: 1979-08-15
Abstract: PURPOSE: To conserve blast power and eventually total energy required for the  whole air-conditioning system by adopting a blast system using an air convection  generated by temperature difference, in the air-conditioning system.  
     CONSTITUTION: Cool air flows in the arrow-pointed direction by an evaporator 5 and blower 7. In the air-conditioning duct 9, it is sent out by blower 7 centering around the evaporator 5. At that time, the air enters chambers 1 u , 1D from the upper duct 2 because change-over damper 4 2  is closed. Further it comes out of the lower duct 3 1  as a descending natural air current, thus forming a circulating cooling cycle. When it comes to the heating cycle, the process is an opposite to the above. Hot air circulates by means of blower 8 as indicated by a broken arrow line. In this way, an ascending or descending natural air current is obtained without the help of forced circulation on account of the difference in air specific gravity in the room and air-conditioning duct system. Power required for blowing is minimized to ventilation resistance for the air-conditioning duct system only. Accordingly conserved blast power contributes toward the energy conservation for the whole air-conditioning system.
