Title: Encoding and decoding system
Inventor: KATOU MASAAKI
IPC: G11B20/14
Filed: 1983-08-17
Abstract: PURPOSE:To obtain an encoding system which facilitates a self-clocking by converting some of 0 code in a code word string having a maximum inversion interval in a 3PM system into 1 code for encoding into a binary data string, and reconverting the data string for decoding. CONSTITUTION:And encoder 13 converts a data word with 3-bit length into a code word with 6-bit length according to a conversion rule and a logical operation is performed. When a code word 101 is detected, the output of the encoder 13 and the output 101 of a 6-bit register 16 are converted into 010 with the output of a detector 15. The code conversion from a table (a) to a table (b) is carried out by detectors 17, 20, and 21 and exclusive ORs 23, 24, 25, 26, 27, and 29, and a code word string wherein the maximum number of 0s between the adjacent 1s is limited to 8 is outputted to a terminal 30. Thus a specific pattern is detected when the number of 0s between the adjacent 1s is large and converted into a code word pattern that the 3PM system does not have to limit the number with the succeeding 0s by this encoding system.

Title: Heat accumulator
Inventor: OZAWA TAKEO
IPC: F28D20/00
Filed: 1986-06-27
Abstract: PURPOSE:To simplify the structure, reduce the cost and improve the heat conducting performance by arranging heat conducting pipes disposed inside the shell in such a manner that the pitch is denser for heat conducting pipes located in the upper and lower layers and the pitch is larger for heat conducting pipes located in the middle layer, and/or by making the heat conducting pipes located in the upper and lower layers to have fins. CONSTITUTION:Among heat conducting pipes 3... disposed inside the shell, the pitch p0 of the heat conducting pipes 3... located in the upper and lower layers l1, l2 is made smaller, and the pitch (p) of the heat conducting pipes 3... located in the middle layer l3 is made larger. Further, the heat conducting pipes 3... in the upper and lower layers l1, l2 are fitted with fins 10. In this manner, the heat conduction is enhanced in the upper and lower layers where the heat conducting performance is significantly affected, and a simplification can be done for the area where there is less influence to the heat conducting performance, allowing a reduced cost. Moreover, the interior of the shell is made in a double structure by installing an inner shell 11 along the shell 2 via multiple supporting plates 12 to reduce the heat dissipation from the external surface.

Title: Core holder for core setter
Inventor: SAKOTA MASARU
IPC: B22C9/10
Filed: 1985-07-08
Abstract: PURPOSE:To permit the vertical movement and turning of hooks for holding a core in a normal position by penetrating engaging rods into an oscillation arms pivotally supported to a core setting body and largely taking the descending stroke of a pressing member to be pressed to the oscillation arms. CONSTITUTION:The pressing member 34 descends to contact with rollers 33 of the engaging rods 27 when a core setter 13 descends down to the position right above a core 5. The rods 27 are thereby pushed downward by overcoming the energy of the 2nd energizing means 31. The member 34 contacts with rollers 32 of the oscillation arms 26 and turns the arms 26 in the direction for opening the same toward the outside by overcoming the energy of the 1st energizing means 30 so that the hooks 28, 29 are detached from the core 5. The arms 26 turn in the direction where the hooks 28, 29 are closed and the rods 27 start ascending when the member 34 ascends. The core 5 is lifted by the subsequent rise of the rods 27. The member 34 detaches from the rollers 33 of the rods 27. The damage and positional deviation of the core are prevented by such mechanism.

Title: Drainage system for vehicular air conditioner
Inventor: IIJIMA KENJI
IPC: B60H1/32
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To make adequate the air flow in a lower layer, which is passed through an evaporator, and drain an upper layer by a simple construction by which a part such as a drain pipe can be eliminated from an upper side drain pan. SOLUTION: An evaporator 16 is accommodated inside an assembly of an upper side case 23 of an upper layer 5 and a lower side case 24 of a lower layer 8, which are assembled in the form of folding palms, an upper side pan 25 formed separately from both the cases 23, 24, is formed to a partition wall 9 between both the cases 23, 24 in the downstream of the air flow of the evaporator 16, in the form of a trough allowing catched water to flow aside. The upper side drain pan 25 catches water scattered from the evaporator 16 by the air flow of the upper layer 5 to allow the water to flow aside, and drains the water to a drainage passage 27 provided close to the side face of the lower side case 24.  Thus, the drainage passage 27 connected to the upper side drain pan 25 does not make resistance to the air flow in the lower layer 8, which is passed through the evaporator 16, and thus an adequate air flow is ensured in the lower layer 8.
