Title: Variable length coding device and method, variable length decoding device and method, variable length code processor and image-coding and decoding device
Inventor: FUKUZAWA YUJI
IPC: H04N19/423
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of a memory which stores a table, used in variable length coding and decoding operations. SOLUTION: The level parts, exceeding 7 among run length RUN and LEVEL (level absolute value) with which the variable length codes associated are assigned in advance and expressed at the parts where the variable length codes are not beforehand associated out of 0 to 31 run lengths and 1 to 7 levels respectively. In such cases, a range of 1 to 40 is changed to a range of 1 to 7 for the levels to which the variable length codes are assigned, although 0 to 31 run lengths to which the variable length codes are assigned are kept unchanged as they are. As a result, a level can be expressed in three bits.

Title: Control method for operation of system linkage equipment
Inventor: MATSUKAWA MITSURU
IPC: H02J3/32
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To prevent waveform distortion of injection current at linkage points and thus control operation among electronic power converters through simple constitution and processing, regardless of the number of the electronic power converters. SOLUTION: Injection current and system voltage of inverter output at a linkage point 4 are measured, and the present values for the active power and reactive power of the inverter output are calculated from the result of the measurement. The components of a current phase shifted by 90 deg. from the phase of the system voltage of the differences between the respective set values and the present values are vector-synthesized to determine a target value for injection current. The difference between the target value and the measured value for injection current is vector-synthesized with the measured value for system voltage, to form an output control signal common to electronic power converters 1a-1n. The output currents of the converters 1a-1n is feedback-controlled, using the output control signal to control the injection current to the target value.

Title: Double lock mechanism for electric connector
Inventor: MATSUMOTO MITSURU
IPC: H01R13/639
Filed: 1989-07-03
Abstract: PURPOSE:To check male and female housings for incomplete coupling as well as double locking, and prevent the occurrence of an incomplete coupling condition. CONSTITUTION:When a coil spring 15 is mounted on the spring retaining pin 13 of a slide lock C and inserted into a lock chamber 7, the stopper 14a of the slide lock C comes in contact with the stopper 10a of the lock chamber 7, thereby deflecting a flexible retaining piece 10 outward. When the stopper 14a goes over the stopper 10a, the slide lock C is temporarily locked. Then, a male connector housing A is coupled to the hood 6 of a female connector housing B. If the coupling condition is complete, the retaining projection 5a of the locking arm 5 of the male connector housing A comes to be engaged with a hooking hole 6a in the hood 6, thereby ensuring a primary locking condition. In the aforesaid state, when the slide lock C is pushed forward against the resilient force of the coil spring 15, a lock plate 12 advances and the hooking hole 12a comes to be engaged with the pressing part 5b of the locking arm 5. As a result, a secondary locking condition is obtained and, therefore, both housings A and B are double locked.

Inventor: TANMACHI MASAMI
IPC: H01B3/44
Filed: 1987-07-08
Abstract: PURPOSE:To obtain excellent oil resistance, water resistance, and heat resistance by adding N,N'-m-phenylenedimaleimide and baked clay to the specific ethylene propylene rubber and forming and bridging an insulator and a sheath. CONSTITUTION:A composition material containing N,N'-m-phenylenedimaleimide 0.5-5pts.wt. and baked clay 50-150pts.wt. against ethylene propylene rubber 100pts.wt. with the iodine value of 20 or less is used to form an insulator and a sheath, and the insulator and the sheath are bridged to produce an electric wire/cable. The electric wire/cable with excellent oil resistance, water resistance, electric characteristics, and heat resistance can be thereby obtained. If the iodine value of ethylene propylene rubber exceeds 20 in this constitution, the heat resistance is reduced. If the addition of N,N'-m-phenylenedimaleimide is less than the above range, sufficient bridging is not obtained, if it exceeds the range, the workability is reduced. If the addition of baked clay is less than the above value, the oil resistance is reduced, if it exceeds the value, the mechan ical characteristics and workability are reduced.

Title: Self-drilling tapping screw
Inventor: ZAIKI MASAMI
IPC: F16B25/10
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a self-drilling tapping screw of comparatively low fastening torque. SOLUTION: A columnar drill part 10 with a conical tip having diameter higher than the root diameter of a screw thread 5 and lower than the crest diameter thereof is formed at the tip of a leg part 3. Two guide grooves 13 are formed throughout a range extending from the tip of the drill part to the starting position of the screw thread 5 of the leg part 3. An escape groove 20 is formed in a similar manner described in the root part of the screw thread 5 between the starting position of the screw thread 5 and the rear end of the drill part 10. Besides, the angle of the screw thread is set to 40-45 deg. and a distance between the roots 6 is increased.  Since a self-drilling tapping screw is formed in a manner described above, chips continuously passes through the escape groove from the guide groove and is moved to the root of the screw thread and choking with chips between the wall surface of a prepared hole and the groove does not entirely occur. Further, since a screw thread angle is low, a screwing-in force is weak, and during screwing in, a smooth screw fastening work is effected without being influenced by the finish surface of the screw thread. Further, since a head part seat surface makes contact with a work, a screw floating state is prevented from occurring.

Title: Lead-acid battery
Inventor: HOSHIHARA NAOTO
IPC: H01M4/73
Filed: 1988-07-08
Abstract: PURPOSE:To lengthen the cycle life including deep discharge by forming a layer containing large amount of tellurium on the surface of leadcalcium base alloy grid. CONSTITUTION:The oxidative corrosion layer of a lead-calcium base alloy grid is dense and easily comes off. If a layer containing a large amount of tellurium exists on the surface of the grid, the porosity of the oxidative corrosion layer of the grid is increased, and adhesion between the grid and an active material is maintained. A layer containing large amount of tellurium or a mixture of tellurium and tin is formed on the surface of the lead-calcium base alloy grid. If the content of tellurium is 0.005wt.% or more, sufficient effect is expected. If it exceeds 30wt.%, the maldistribution of tellurium is increased, the melting point of the grid increases around 900 deg.C, and productivity of the grid is decreased. The existence of tin together with tellurium shows similar effect. The cycle life including deep discharge is lengthened.

IPC: H05K3/06
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To sufficiently, smoothly and reliably carry it even when rigidity of a base board is comparatively small by positioning guide rollers in a guide position to guide an under surface of the base board when the base board is carried in the prescribed direction from an end part separating position. SOLUTION: When guide rollers 100, 102, 124 and 126 are arranged, in the first place, a base board 40 is entered into a slight clearance existing between the guide roller pairs 100 and 124 or 102 and 126. Next, the base board 40 is introduced between pressure connection rollers 96 and 120 or 98 and 122 by the guiding action of the guide roller pairs 100 and 124 or 102 and 126. Apparent rigidity of the base board 40 is increased by support by the guide roller pairs 100 and 124 or 102 and 126, and in this way, it is sufficiently and smoothly introduced between the pressure connection roller pairs 96 and 120 or 98 and 122. As a result, the possibility that the base board 40 is curved in the width direction or a side edge part of the base board 40 is damged, is eliminated.
