Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To provide the user data with high error correction ability by making a sector showing that the user data effective for user data existence discriminative information don't exist and a sector showing that the user data effective for the user data existence discriminative information exist to coexist in an ECC block. SOLUTION: A data sector 1101 where the user data used by a host device exist coexists with the data sector 1101 where the user data don't exist, and they are discriminated clearly by sector discrimination area information. The suitable data are buried in the main data area of the sector where the user data don't exist, and an inner code parity and an outer code parity are generated based on the data required for calculating an error correction code. When the user data are reproduced from an optical disk, since a physical sector required for constituting the ECC block is completed, high reliability user data are obtained.

Title: Electric melting furnace with split melting bath vitrification of high radioactive waste
Inventor: IGARASHI HIROSHI
IPC: C03B5/00
Filed: 1987-08-21
Abstract: PURPOSE:To contrive miniaturization of a melting furnace, improvement of its reliability, extension of its use life and improvement of its maintenance by forming structure in which the melting furnace is partitioned by non-conductive durable substance. CONSTITUTION:A side wall refractories 1 normally use the refractories having superior erosionproof against melting glass. Two metal made freeze valves are attached to glass entrances of the bottom of a melting vessel. Furnace bottom refractories 2 are installed to the circumference of the freeze valves 6 and use the same as the side wall refractories 1. Partitioning refractories 14 are installed to the furnace bottom and the melting bath is divided into two parts. The partitioned refractories use extremely non-conductive refractories whose caloric value is sufficiently small, as compared to the caloric value of glass in the melting bath by directly sending electric current with superior erosionproof against melting glass. Therefore, the depth of the melting bath can be lessened, as compared with the melting surface area and the distance between electrodes with the prevention of concentration of current which is made to flow in the deposition in the neighborhood of the furnace bottom containing highly concentrated platinum group elements.

Title: Spool valve
Inventor: MARUMOTO IKURO
IPC: G05D16/10
Filed: 1991-07-25
Abstract: PURPOSE:To avoid stick slip, delay in action, the occurrence of scuffing and the like by preventing a spool from being hydraulically locked. CONSTITUTION:A thin film 100 made of titanium nitride is formed over the outer circumferential surface of the second land section 62 of a spool 58 in such a way as to be thin at the side of a control pressure port 78, but to be thick at the side of a first low pressure port 74. Since a clearance between the outer circumferential surface of the second land section 62 and the inner circumferential surface of a valve port 52 is large at the control pressure 78 side, but small at the first low pressure port 74 side, unbalance liquid pressure in the direction correcting eccentricity takes place in the circumference of the second land section 62 when the spool 58 is one-sided, so that the occurrence of hydraulic lock is thereby prevented. This constitution thereby allows the spool 58 to be smoothly slid in response to the degree of the excitation of a coil 106, and the liquid pressure control of respective cylinders can be enhanced in accuracy.

Filed: 1982-11-30
Abstract: PURPOSE:To obtain a distance measuring sensor, which is mounted on an unmanned conveying robot and can measure the distance accurately regardless of the reflecting characteristics of a body to be measured, by using laser beams. CONSTITUTION:A laser beam is projected from a laser device 1 through a rotary mirror 3 and rotated at an equal angle speed omega. When the spots of the laser beams are projected on positions C and D on a floor 2, the spots are received by light receiving devices 4 and 6 through a condenser lens 5. A counter 8 counts clock pulses CLK based on the output pulses from the light receiving device 4. The counter 8 become inoperative by the output pulse signal from the light receiving device 6. A latch circuit 9 latches the counted value of the counter 8, and outputs the value to an operating circuit 10. The counted value indicates a time (t) from the time point when the light receiving device 4 receives the spot to the time point when the light receiving device 6 receives the spot. When a body 12 is located at a position E, the light receiving device 6 receives the spot of a position F. By measuring the time (t), the distance (l) of the body 12 can be obtained by the expression in the Figure.

Title: Method for washing small parts stuck with fats and oils and fine powder
Inventor: MASUNARI YOSHIKAZU
IPC: C23G1/00
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to wash away fats and oils and fine powder from small parts and to rapidly wash a large quantity of these small parts by housing the small parts into a vertical type containing cylinder which is installed in a washing column and includes a water flow hole only in its bottom, then forcibly circulating a detergent in this vertical type containing cylinder. SOLUTION: The detergent 2 in a liquid tank 1 is first forcibly circulated in a liquid circulating line 3 by operating a liquid feed pump 5 at the time of washing objects (a) to be washed. Namely, the detergent 2 is introduced from a forward path 3a through the upper chamber 4a of the washing column 4 into the vertical type containing cylinder 7 where the objects (a) to be washed are washed while the detergent is forcibly passed in an axial direction. The detergent 2 is thereafter returned through a backward path 3b to the liquid tank 1 while the detergent is forced to rise in the lower chamber 4b of the washing column 4. At this time, valves V1 , V2 are respectively opened and valves V3 to V5 respectively closed.  The vertical type containing cylinder 7 has no water flow hole in its cylindrical part 7b and has the water flow hole only in its bottom 7a and, therefore, the detergent 2 flows at a high velocity from the top end toward the pottom end and comes into efficient contact with the objects (a) to be washed, thereby washing the objects.
