SOLUTION: The encryption apparatus 10 obtains ciphertext C according to C≡Me (mod n) form plaintext M by using a first secret key which is N (>=2) pieces of prime numbers p1, p2,..., pN, a first public key (n) which is the products p1k1, p2k2... pNkN when k1, k2,..., kN are defined as arbitrary positive integers, a second public key (e) which satisfies ed≡1 (mod L) when the least common multiple of p1-1, p2-1,..., PN-1 is defined as L and second key (d). The decryption apparatus 19 restores the plaintext M by determining remainders Mp1k1, Mp2k2,..., MpNkN having p1k1, P2k2,..., pNkN of the pain text M respectively as moduli by using prescribed loop computation and further by applying Chinese remaindering theorem with respect to the first secret key.

Title: Memorandom sheet for copying
Inventor: SENJU HIROYUKI
IPC: B42F7/06
Filed: 1994-03-08
Abstract: PURPOSE:To produce a copy in which a memorandom is freely written without soiling a copying original by superposing a transparent cover on the upper surface of a transparent or white sheet in a state where one end is fixed. CONSTITUTION:The transparent cover 2 is superposed on the upper surface of the transparent or white sheet 1 with one end fixed. The memorandom is written on the sheet 1 with a marker for a white board, and the sheet 1 is covered with the cover 2 and placed on the surface of a copying machine. Then, the copying original such as a book or a photograph is placed thereon and copying is performed, thereby producing the copy where the memorandom is written. When the part superposed on the sheet of the copying original is desired to be made void, the white sheet is used, and in the case of copying as it is, the transparent sheet is used. Since a material such as plastic, which is thin and soft, is used as the sheet, the sheet does not hinder in the case of copying, and it is hardly deviated when it is positioned once. After the sheet is used, it is easily taken out and the memorandom is easily erased with an eraser, thereby, the sheet is used with ease any number of times.

Title: Manufacture of resist pattern
Inventor: NAKAGAWA TAKAYUKI
IPC: H01L21/30
Filed: 1979-06-18
Abstract: PURPOSE: To make a fine pattern, by exposing a diazo-type resist to an electron beam of 40A/cm 2  or less in electrical current density, thereafter treating the resist with heat at 100°C or less and irradiating ultraviolet rays upon the entire surface of the resist to change the positive resist into a negative one.  
     CONSTITUTION: A diazo-type resist is coated. The resist is then treated with heat at about 80W95°C for about 20 minutes. When the resist is exposed to an electron beam, the quantity of the exposure is controlled so that the film remaining ratio after development should be limited to about 70%. If the positive resist is excessively irradiated with the electron beam, bubbles are produced. After the exposure, the resist is treated with heat at 100°C or less for about 20 minutes. Ultraviolet rays are then irradiated upon the resist at the rate of 100W400mW/cm 2 . The development is effected by an alkaline liquid diluted at most twice. The positive resist is thus changed into a negative one. This results in facilitating the manufacture of a fine pattern.

Abstract: PURPOSE:To decrease the coefficient of dynamic viscosity of lubricating oil on the inner surface of a liner part and to reduce a friction loss between a cylinder and a piston, by a method wherein, in a device provided at the outer periphery of a liner part with a water cooling chamber, the thickness of the liner part is so formed that its lower part is thicker than its upper part. CONSTITUTION:Cooling water, discharged from a cooling water 21, flows to the lower part of a cooling water jacket 51, and after it cools the outer surface of a liner part 50, the cooling water incomes to a cooling water reservoir 24 of a cylinder head 13 through a communicating port 23 formed in an upper part. Thereafter, the cooling water flows to a thermostat 27 through a piping 26 by means of a cooling water outlet pipe 25. A part thereof further flows through a radiator 28 and a piping 29, and the remaining part flows to a cooling water pump 21 through a bypass piping 31. In this consitution, the thickness of the liner part 50 formed to the interior of a crank case 11 of a point on the the liner part increases the further downward along the liner part this point is situated. This causes the width of a cooling jacket 51 of this point along its surface to decrease the further downward along its surface this point is situated, resulting in the possibility to prevent cooling of the lower part of the liner part 50 to achieve a desired purpose.

CONSTITUTION:The annular member 8 is inserted under an anti-corrosive layer 3 firstly. The annular member 8 has the larger internal diameter size than the external diameter size of the cable core 2 and there is therefore a slight gap formed between the inner peripheral surface of the annular member 8 and the outer peripheral surface of the cable core 2. A bind wire 5 is wound around the peripheral surface below the anticorrosive layer 3 while upper parts of plural wires 6' are made to contact the peripheral surface below the anticorrosive layer 3 in the vertical direction. In this case, the bind wire 5 is clamped with large clamping force to prevent the wires 6' as coupling members from coming out and also press the lower part of the anticorrosive layer 3 against the peripheral surface of the annular member 8 tightly. Then, the lower ends of the respective wires 6' are coupled with the weights 7 to place a specific load on the anticorrosive layer 3.
