Title: Disk drive device and detecting method of unrecorded area
Inventor: TAKIGUCHI TAIZO
IPC: G11B7/005
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To enable execution of a blank check of high reliability even when there is nonuniformity in characteristics for individual apparatuses, by setting a threshold to be used for the blank check on the basis of the result of comparison of a threshold for regulation with a playback RF signal. SOLUTION: A playback RF signal regulated to have a prescribed gain by a variable gain setting part 33 is inputted to a peak-bottom detecting part 78, and levels of the peak and the bottom of the amplitude thereof are detected. The level of the envelope waveform of the playback RF signal subjected to the detection is inputted to one side of a comparator 101, while a threshold TH for a blank check outputted from a drive control unit 30 and converted into an analog voltage value through a D/A converter 100 is inputted to the other side. In the comparator 101, the threshold TH and the level of the envelope waveform of the playback RF signal are compared with each other, and a comparison signal DT thereof is outputted to execute a blank check operation. Herein, an unrecorded area is checked out according to whether the comparison signal DT is of an H level or an L level, for instance.

Title: Fuel rod
Inventor: SAKUYAMA TADASHI
IPC: G21C3/17
Filed: 1990-08-07
Abstract: PURPOSE:To prevent dislocation of getter tube for water absorption during assembling a fuel rod by providing a wafer at one end of coilspring and fixing a disk at the other end. CONSTITUTION:A water absorption getter tube 18 supported at its end by a wafer 17 is arranged inside of a coilspring 16 as shown in the figure and this has a function of absorbing water in a fuel rod 2 because if there is anything inside after the assembling of the fuel rod 2, then it will evaporate during reactor operation to cause fuel damage. And a thin disk 19 is fixed by welding at the upper end of the coilspring 16. Also, the lower end opening of the coilspring 16 is closed by the wafer 17 and the upper end closed by the disk 19. By this, the dislocation of the water absorption getter tube 18 during assembling the fuel rod is prevented.

Abstract: PURPOSE:To properly control the disabling of the first throttle device and the enabling of the second throttle device by constituting a spring device exciting a piston to the outlet side with the first spring and the second spring compressed to the preset length in advance. CONSTITUTION:A spring device exciting a piston 18 to the outlet 14 side is constituted of the first spring 31 compressed when the piston 18 is moved to the inlet 12 side and having small tension and the second spring 23 compressed when the piston 18 is moved to the inlet 12 side over the preset quantity and compressed to the preset length in advance.

Title: Printing head life detecting device
Inventor: SAGAWA NOBUO
IPC: B41J29/46
Filed: 1987-08-21
Abstract: PURPOSE:To easily detect the life of a printing head, and to perform a printing head life detecting in which its printing quality can be easily maintained and its maintenance can be easily conducted by providing a counter for counting the driving number of a printing pin having a high using-frequency, and providing displaying function for displaying the life in the counter. CONSTITUTION:A counter 2 has a rotatable ratchet 2-2 supported to a shaft 2-1 and a ratchet pawl 2-3 for rotating the ratchet. The pawl 2-3 is secured to a plate 2-5, and one end of the plate 2-5 supported to a shaft 2-5 is disposed oppositely to a magnet 2-7. When a carry signal of a counter 3-1 is input to the magnet, the plate 2-5 is attracted to the magnet 2-7, and the pawl 2-3 allows the ratchet 2-2 to rotate at a predetermined angle. A scale plate 2-4 secured to the ratchet 2-2 is rotated by the carry signal. Then, a red is displayed at a position corresponding to the number of driving pulses of presumed life, such as at 10 stepping position of the plate 2-4. When the red is detected from a display window, an operator conducts a countermeasure as the life of a printing head is over.

Title: Method for controlling fuel injection for internal combustion engine
Inventor: KONO KOZO
IPC: F02D41/20
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To eliminate an overlapping between fuel injection during compression stroke and fuel injection during intake stroke without deteriorating the characteristic of exhaust gas and fuel consumption. SOLUTION: In a fuel injection control method in which fuel is injected into engine cylinders C1 to C4, successively, by injectors through fuel injection during compression stroke or fuel injection during intake stoke, if an initial preparation and drive period D4a for an engine cylinder C4 overlaps with an initial preparation and drive period D3a of injection for an engine cylinder C3 during compression stroke at least in part, the period (t) of injection during intake is shifted so as to be advanced by a time Δt in order to prevent the initial preparation and drive period D3a for the engine cylinder C3 overlapping with the initial preparation period D4a for the engine cylinder C4. As a result, the injection during intake stroke is carried out at a relatively early stage during the intake stroke, thereby it is possible to sufficiently evaporate fuel injected before ignition.

Title: Semiconductor device
Inventor: HATTA YASUSHI
IPC: H01L29/80
Filed: 1985-09-24
Abstract: PURPOSE:To avoid soft errors induced by alpha-rays by a method wherein, in an MESFET, a gate electrode is extended onto the parts beyond an N-type region and the extended parts are formed on the passive regions of a substrate with insulating layers in between. CONSTITUTION:A gate electrode 11 is formed so as to be contacted with a substrate 2 and, when a bias is applied to the gate electrode 11, generation of a depletion layer in the substrate is effectively avoided by employing a structure wherein the extended parts 11a and 11b of the gate electrode are formed on the passive regions of the substrate with insulating layers 12 in between. This depletion layer has a property that pairs of electron-positive hole are produced by incident alpha-rays into it and it is considered as a main factor of soft errors that the electrons of those pairs of electron-positive hole are attracted to an active region. Therefore, with this constitution, soft errors induced by alpha-rays can be avoided.

Title: Rotary magnetic head
Inventor: SHIBUKAWA KAZUO
IPC: G11B15/61
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a high reliable rotary magnetic head by providing a surface closing a gap between a head fitting window provided on an outer peripheral part of a rotary head cylinder and a head chip on a head base. SOLUTION: A magnetic tape 6 travels while winding around the outer peripheral part of the rotary head cylinder 4. At this time, air pressure occurs between the magnetic tape 6 and the rotary head cylinder 4, and the magnetic tape 6 floats minutely for the rotary head cylinder 4. Since the gap between the head chip 2 and the head fitting window 5 is closed by the wall part 3a of the head base 3 in the radial direction of the rotary head cylinder 4, negative pressure occurring in the gap between a magnetic head and the head fitting window 5 is reduced remarkably. Thus, contact between the magnetic tape 6 and the rotary head cylinder 4 is evaded, and the failure such as clogging of a head and a traveling impediment, etc., due to sticking between the tape 6 and the cylinder 4 are prevented.
