Title: Magnetic disk controller
Inventor: TOMITA HIROSHI
IPC: G06F3/06
Filed: 1986-05-31
Abstract: PURPOSE:To recognize a data being in error at read and not written normally by inverting an added error detection correction code to a write data detecting a data under run at write. CONSTITUTION:In detecting the data under run, a processing circuit 130 drives a circuit 140 to generate an error detection correction code being the inversion of the normal value, transfers the result to a buffer 120, where the write data stored therein and the data added with the correction code are written in a magnetic disk device. In reading a data block having a data run at the data write, the central processing unit judges the occurrence of a data error and that the block is defective.

Title: Lack-of-oxygen preventing safety device in combustion equipment
Inventor: TAKAHASHI MUTSUHIKO
IPC: F23N5/24
Filed: 1992-05-19
Abstract: PURPOSE:To provide a lack-of-oxygen safety device in combustion equipment for use in detecting the lack of oxygen at a specified concentration of oxygen. CONSTITUTION:There are provided a blower 5, a burner 2 oppositely arranged to a gasifier 3 connected to a solenoid pump 11, a flame rod 6 for use in detecting a flame current in a burner flame, and a control unit 13 for stopping combustion when the flame current detected by the flame rod 6 is less than a predetermined lack-of-oxygen sensing level in the case that the number of revolution of the blower 5 is periodically and temporarily increased at a predetermined interval after reduction of the flame current value by a certain degree only under a fine combustion state. Then, under the normal state in which the lack-of-oxygen is less increased, the number of revolutions of the blower 5 is not increased to reduce noise and in addition, when the lack-of-oxygen is increased, the number of revolutions of the blower 5 is periodically and temporarily increased to estimate the lack-of-oxygen in advance, resulting in that the flame current is lowered faster than that under the normal air blowing volume and the lack-of-oxygen sensing level can fulfill a concentration of oxygen.

Title: Optical disk memory medium
Inventor: ABE MICHIHARU
IPC: G11B7/24073
Filed: 1984-06-19
Abstract: PURPOSE:To improve a tracking error signal level standardized at a mean reflecting light level without comlicating the manufacturing process, by setting the ratio of the intermitted part of guide grooves at a preformat section formed by the intermission of the guide grooves to the entire preformat part at 25% or less. CONSTITUTION:An information track on an optical disk memory medium is composed of guide grooves 10 and a preformat section 10C formed by the intermission of the guide grooves 10. Information to be recorded is written on the guide grooves 10 with laser light and thus an unrecorded part 10A and recorded bit part 10B are obtained. In respect of a part 10C, when the cycle of the intermission of the guide grooves 10 is represented as A and the distance between two adjacent guide grooves 10 is represented as B, the ratio of intermission of the guide grooves 10, (B/A)X100%, is set at 25% or less. Therefore, the tracking error signal level which is standardized at a mean reflecting light level can be improved effectively even at a preformat section without requiring any complicated manufacuting process.

Filed: 1992-05-19
Abstract: PURPOSE:To prevent damage by retreating a floating type head to a safe position away from a cartridge while the head is held at a prescribed height at the time of loading or unloading the cartridge. CONSTITUTION:This magneto-optical disk drive starts a motor 20 by confirming that a moving integral type head 6 returns to R40 (lifting position). The moving integral type head 6 is held pressed to a contact part 37a by a linear motor before the floating type magnetic head 4 begins to be lifted up. As a result, the moving integral type head 6 can be surely restrained by a lock pin 30 even if the magneto-optical disk drive is set inclinedly or an impact is applied to the magneto-optical drive during the operation.

Title: Fuel supply device of internal combustion engine
Inventor: SAKURAI TAKUYA
IPC: F02M37/00
Filed: 1994-06-08
Abstract: PURPOSE:To provide a fuel supply device for dead end type internal combustion engine, with which it is possible to reduce dispersion in the fuel injection amount from cylinder to cylinder and to present a good stability in the engine operation. CONSTITUTION:A fuel gallery 3 in connection with fuel injection valves 2A-2D of an engine 1 is connected with a fuel supply passage 4, to which the fuel sucked up from a fuel tank 6 by a fuel pump 5 is supplied. The part 8 corresponding to the dead end in a conventional arrangement is connected with a go-around passage 9, whose other end is in connection with the upstream part (fourth cylinder upstream part) of the fuel gallery 3. Therefore, there is no risk that the fuel getting a high temp. upon receiving the combustion heat of the engine 1 stagnates in the gallery 3, which is likely in a conventional fuel supply device of dead end structure, but the fuel is exhausted to the passage 9 side, so that the tendency of the fuel temp. increasing as approaching the dead end can be relieved and also the fuel temp. be sunk which should permit suppressing the dispersion in the fuel injection amount from cylinder to cylinder.

Title: Processing method of semiconductor substrate
Inventor: KASAHARA JIROU
IPC: H01L21/324
Filed: 1979-10-01
Abstract: PURPOSE:To prevent evaporation of V group elements from a substrate by a method wherein a III-V group semiconductor substrate is contacted to a V group element containing semiconductor indicating a higher V group element decomposition pressure than that of the former and a heat treatment is performed. CONSTITUTION:On an ion-injected GaAs substrate 1 to be heat-treated, GaAs substrate 2 on which more amount of ion has been injected is closely adhered, they are laminated on a quartz susceptor 5 and a heat-treatment is performed. Hence, as a larger damaged region is obtained in proportion to the increasing amount of ion injection and an As decomposition pressure is raised, the As decomposition pressure of the substrate 1 is relatively lowered, and a thermally stabilized heat treatment can be performed. Besides, when an InAs is used as a substrate 2, it has a high decomposition pressure than the GaAs and an ion injection into the substrate 2 becomes unnecessary.

Abstract: PURPOSE:To protect a piezoelectric body from breaking at the time of repeated operation as well as the fixed end of the piezoelectric body from peeling-off by a method wherein one end or both ends of the piezoelectric body is connected to a plate-shaped coupling member. CONSTITUTION:The lower end of a piezoelectric body 2 is fixed on a connecting member 14, which has been connected to mounting member 1 with metal plates 15 and has been integrally formed in one body with the mounting member 1. In such a constitution, even when a reaction force, which is transferred to the member 14 at the operating time, includes a component to apply a bending stress to the piezoelectric body 2, the stress concentrates in the members 15 and is made to bend, and the bending stress, which is applied to the piezoelectric body 2, is remarkably reduced. As a result, the breaking of the piezoelectric body 2 and the peeling-off of the fixed end of the piezoelectric body 2 are not caused at the time of repeated operation.

Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a switching power supply circuit having a multi-output power supply voltage system and capable of shutting down the whole power supply when high power supply voltage drops and approaches low power supply voltage. SOLUTION: The multi-output type switching power supply circuit is constituted of a high output power supply 5 V system and a low output power supply voltage 3.3 V system and the 5 V system is constituted of a three-terminal regulator 144 having a shunt regulator function. When the output of the 5 V system becomes an overload state, its output voltage is dropped and may be reduced lower than the output voltage of the 3.3 V system, the power supply is shut down interlocking with an overcurrent protection circuit 151 in the 3.3 V system. Consequently a unit to which power supply voltage is to be applied can be prevented from being damaged due to the latch-up phenomenon of a two-power supply type semiconductor.
