Title: Rankine cycle device
Inventor: ISHIDA TETSUYOSHI
IPC: F01K9/00
Filed: 1989-10-25
Abstract: PURPOSE:To vary the output ratio between an electric output and thermal output over the wide range by providing a pressure changing means by which pressure in an absorption type condenser is changed. CONSTITUTION:In a Rankine cycle device having an absorption type condenser 5, regulation of opening degree of flow rate adjusting valves 9, 12 is carried out by an electric and thermal output regulator 13 so that the temperature of cooling water 31 detected by a thermometer 17 and the flow rate of the cooling water 31 detected by a flow meter 15 become suitable for the output of a power generator 4 detected by an electric output meter 14. Pressure in the absorption type condenser 5 drops when the temperature of the cooling water 31 falls, and an electric output ratio is increased. On the other hand, when the temperature of the cooling water 31 rises, pressure in the absorption type condenser 5 is raised, and the electric output ratio is decreased. It is thus possible to vary easily the output ratio of the electric output and the thermal output over the wide range.

Each frame section 13 and 14 is opened at its upper surface, and each large frame section 14 is also opened at its lower surface. The blocks 11a, 11b and 11c are vertically piled up. In this case, the lower opening 18 of each large frame section 14 in the blocks 11c, 11a and 11b at the upper side is tightly piled up on the upper opening of each small frame section in the blocks 11a, 11b and 11c at the lower side. Deep planting recessed sections 46 largely opened upward can be distributed in a checked shape by letting each small frame section 13 and each large frame section 14 be vertically adjacent to each other.  Therefore, a comparatively big tree can thereby be planted at a high planting density.

Title: Recording device and method, reproducing device and method, and recording medium
Inventor: TSUJII SATOSHI
IPC: G11B20/10
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent an externally referenced form file consisting of only a reference information storage section from referencing an unintended file. SOLUTION: An optical disk 20a is loaded to an external drive 71, which copies or moves one file or more recorded in the optical disk 20a to a hard disk 72 of a personal computer 70. The personal computer 70 edits the files and again copies or moves the result of edit to the optical disk. The result of edit is the externally referenced form file to its reference information storage section of which reference file information and a specific character string generated from a disk ID are imbedded. In the case of reproducing the optical disk recording the result of edit, checking by the character string is conducted. That is, the coincidence between the character string in a file 62 of the result of edit and the character string on the basis of the disk ID read from the disk is detected.  When the disk is the substantial optical disk 20a, since the both are coincident, the reproduction is permitted. However, when the disk is other optical disk 20b, since both the disk IDs are dissident, the reproduction is inhibited.
