Title: Digital leakage compensation circuit
Inventor: CARLSON ROY M
IPC: H03K19/096
Filed: 2002-03-26
Granted: 2003-07-11
Abstract: A digital leakage compensation circuit for compensating for leakage in a dynamic circuit includes a dummy precharge circuit, a dummy input circuit, a dummy evaluation circuit, a dummy latching circuit, a sense circuit and a storage circuit. The dummy circuitry matches the size and layout of corresponding precharge, input, evaluation and latching circuitry in the dynamic circuit so that the leakage can be accurately modeled. The sense circuit senses the leakage and generates a signal, stored in the storage circuit, which causes an adjustable latching circuit to provide additional leakage compensation in the dynamic circuit. Alternatively, the dynamic circuit may include a driving circuit with an adjustable trip point. The sense circuit provides the signal to the driving circuit to adjust the trip point to compensate for the leakage.

Filed: 2002-05-31
Granted: 2005-01-11
Abstract: A method and device for recording information blocks on a record carrier is described. The device has control means 20 for recording and retrieving position data indicative of the position of the recorded information blocks. The control means include a mapping unit 31 for determining in which region the information block is recorded and a detection unit 32. The region is one of a number of consecutive regions constituting the recordable area. The mapping unit records a random signal unit in a unit location in a mapping area. The unit location indicates said region, and the unit length of the random signal unit is smaller then the length of said information block. The detection unit 32 detects the presence of the recorded random signal units in said mapping area and so determines if a region contains at least one information block. The highest written address is found by detecting the highest written unit location in the mapping area, and subsequently searching said region for the presence of recorded marks.

Title: Optical disk device
Inventor: TAKEDA NAOTO
IPC: G11B7/006
Filed: 2002-07-18
Granted: 2005-07-11
Abstract: This invention provides a way to control the tilt of optical disk for an optical disk device that can read and write on an optical disk. The control process includes: Optical pick-up 14, output signals of reflecting beams to a tilt detector 28. Tilt detector 28, sample-holds the signal level of reflecting beams of the write power before pits are formed, and outputs the signal level to a controller 20. The controller 20 changes the tile of the optical pickup 14 into three different states, and compares sample hold valves of each state, and adjusts the tilt to the state that generates the maximum signal level. Since the pits are not formed at that time, the signal of reflecting beams have not affected by pits, the signal level reflects only to the tilt of optical disk 10. This invention enables to control the tilt of the optical disk 10 precisely.

Title: Neutron shielding materials and a cask for spent fuel
Inventor: KAMOSHIDA MAMORU
IPC: G21F5/008
Filed: 2002-10-18
Granted: 2005-08-21
Abstract: The present invention provides a high-polymer neutron shielding material which scarcely reduces the hydrogen number density when exposed to a high temperature of 150 to 200 DEG C for a long time period. A heat-setting type epoxy resin is employed. The base resin is selected from various epoxy resins such as bisphenol A type epoxy resin. The hardener is selected from alicyclic polyamine, polyamide amine, aromatic polyamine, acid anhydride, and so on. These materials are mixed and hardened at a temperature higher than the room temperature. To give a flame resistance to the hardened resin, a fire retardant such as magnesium hydroxide is added to the mixture. To improve the neutron shielding performance of the hardened resin, a neutron absorbing material is added to the mixture. Furthermore, to increase the moderating performance, hydrogenated bisphenol A epoxy resin is used as the base resin or metal hydride or hydrogen absorbing alloy is added. The present neutron shielding material works as a significant neutron shielding material as its hydrogen number density does not go down for a long time under a high-temperature condition and the neutron shielding performance does not go down.

Title: Target device and light detecting device
Inventor: ANDOH TADASHI
IPC: F41J5/02
Filed: 2003-05-09
Granted: 2004-01-11
Abstract: When a light beam shot from a light gun hits a target plate mounted on a target device, the light beam is detected by a beam detected position detecting unit, which generates a current based on the shot impact position of the light beam on the target plate. An extraneous light detecting unit generates a current based on extraneous light applied to the target device. The current generated by the beam detected position detecting unit or a voltage based on the current, and the current generated by the extraneous light detecting unit or a voltage based on the current are supplied to a subtractor, which subtracts the current generated by the extraneous light detecting unit or the voltage based on the current from the current generated by the beam detected position detecting unit or the voltage based on the current, and outputs a differential current or voltage value. Thus, an extraneous light component is removed from the current generated by the beam detected position detecting unit. Thereafter, a position calculating unit recognizes the light beam shot from the light gun and detects the shot impact position of the light beam on the target plate based on the differential current or voltage value.
