Title: Sector processing method for optical disk
Inventor: TENMYO NARIMOTO
IPC: G11B20/10
Filed: 1986-12-18
Abstract: PURPOSE:To attain an automatic processing at the drive processing side even when no ID address is read by describing a sector number to a 1st sector group if no sector of the sector number exists at write and recording a data in the alternative sector of the sector corresponding to the sector number. CONSTITUTION:If the sector number designated from the host at write is not read by the damage of an IO part, the sector number is written in the 1st sector group 1 of the disk. Then the data is written in the alternative sector 6 of a 3rd sector group 3 in a 2nd sector group 2 corresponding to the sector number. Thus, even when the ID number is not read out, the driving device itself processes the data automatically without returning the control to the host side and the workability is improved.

Title: Inductive proximity sensor
Inventor: BUERUNAA SHIYARAA
IPC: H03K17/95
Filed: 1989-11-22
Abstract: PURPOSE: To ensure a relatively large operation interval as compared with the diameter of sensor head with small tolerance and negligible temperature dependency by an arrangement wherein the line of magnetic force closed on the outside of a detector coil induces an AC voltage in the detector coil. CONSTITUTION: A field generating coil 1 is connected with an AC voltage supply 2 and an AC field 3 is generated together with external lines 4-8 of magnetic field. A detector coil 9 is provided concentrically to the coil 1. Lines of magnetic field 7, 8 closed on the outside of coil 9 induce an AC voltage in the coil 9. Lines of magnetic field 4-6 closed in the coil 9 do not contribute to induction of a voltage in the coil 9. AC voltage induced in the coil 9 is converted through an evaluation circuit 10 into a signal. Consequently, a large operation interval can be attained with small tolerance and negligible temperature dependency as compared with the diameter of sensor.

Title: River bed protecting structure and construction method thereof
Inventor: MASAKA KOSEI
IPC: E02B3/02
Filed: 1993-11-08
Abstract: PURPOSE:To absorb the impact of boulders and the like flowing down and prevent the damage of a skeleton by placing asphalt flatly on backing concrete, and fixing a protecting sheet of specified thickness with specified elasticity and strength onto the upper face of the asphalt. CONSTITUTION:An asphalt mastic layer 2 is placed on the upper face of the concrete 1.

This therefore facilitates also the repair of the apron of a dam in the advanced stage of damage and wear, a river bed, and the like. The sheet 3 is fixed by bonding or using bolts. The impact of boulders flowing down can be thereby absorbed by the protecting sheet and the asphalt layer, and the damage and wear of the river bed and the like can be prevented. In addition, this structure can be constructed at low cost and can be applied also to the repair of an existing part.

Title: Production of asphalt
Inventor: ADACHI MASAMICHI
IPC: C10C3/00
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing asphalt by which a load on an operator is reduced; the production time is shortened and oil leakage from a seal of a pump shaft is hardly caused. SOLUTION: The filling of the interior of a distillation column 4 with a light oil in a light oil tank 4 is started and the heating of the light oil is started by ignition, etc., of a heating furnace 8. The oil fed to the distillation column 2 is changed over from the light oil to a vacuum distillation bottom residue in a raw material tank 3 and the distillation column 2 is decompressed. Since the interior of the distillation column 2 is kept at atmospheric pressure during the heat-up and the interior thereof is then replaced with the high-boiling vacuum distillation bottom residue at the time of starting the decompression, foaming of the column bottom is suppressed. The flow control of the light oil, etc., is not required without causing the air suction with the column bottom pump 11 and a load on an operator can be reduced to shorten the production time. The oil leakage from a seal of the pump 11 is hardly caused.
