  • Patent number: 7195110
    Abstract: There is provided a one-way clutch unit that is simple in structure and compact. An annular recess 67 is provided in an inner periphery of a side of a deep groove ball bearing portion 55 of a first inner ring 7 of a first one-way clutch 1, and an end portion on the side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in the annular recess 67. Thereby, the dimension in an axial direction of the one-way clutch unit is reduced by a dimension in the axial direction of the second one-way clutch 2 that is disposed in the annular recess 67.

  • Patent number: 6774713
    Abstract: A leak monitoring transistor is selected from transistors of a semiconductor integrated circuit manufactured in the manufacturing process set to the same condition, and a reference voltage is produced in a reference voltage producing unit according to leak current of the leak monitoring transistor in a standby time period. The reference voltage is lowered as a value of the leak current is increased. An output voltage set to be equal to the reference voltage in an operational amplifier is applied to the other transistors of the semiconductor integrated circuit. The characteristic of the leak currents of the other transistors is the same as that of the leak monitoring transistor. Therefore, when the transistors having the leak currents higher than a designed value are manufactured, the output voltage is lowered due to the leak monitoring transistor having the leak current higher than the designed value.

  • Patent number: 6551829
    Abstract: Disclosed is a dry baker's yeast of a diploid, practical baker's yeast, which is obtained by mating an ATH1 and/or NTH1 gene-disrupted, haploid yeast as produced through gene manipulation of disrupting the ATH1 and/or NTH1 gene in an a-type haploid yeast of which the diploid is practical baker's yeast, with an ATH1 and/or NTH1 gene-disrupted, haploid yeast as produced through gene manipulation of disrupting the ATH1 and/or NTH1 gene in an &agr;-type haploid yeast of which the diploid is practical baker's yeast. The dry yeast does not require sugared water for its re-activation but can be rapidly re-activated only with water. Using the yeast, therefore, breads having good taste can be produced within a short period of time.

  • Patent number: 6512893
    Abstract: A camera of the kind using a cartridge with the cartridge accommodated inside a cartridge chamber is required to ensure that the lid of the cartridge chamber is openable only when film has been rewound into the cartridge. To meet this requirement, there is a known method for unlocking the cartridge chamber lid only when the film has been rewound. However, in the event of some accident, it might become impossible to rewind the film to make the cartridge chamber lid no longer unlockable. To solve this problem, a camera according to the invention disclosed is arranged to make the cartridge chamber lid unlockable in response to a specific operation performed differently from an ordinary photo-taking operation.

  • Patent number: 6353235
    Abstract: A detection test structure making a high-sensitivity detection of damage to gate insulating films from charges entering into contact or through holes during plasma processes is achieved to make a low-cost, high-precision, short-time evaluation of the damages. A plasma damage detector (PD1) comprising an MOS transistor (M1), a first layer wire (IL1), a contact hole group (H10), and a second layer wire (IL2) is integrally formed with a product wafer in the fabrication of the product wafer. After the completion of the product wafer, a lifetime of the MOS transistor (M1) is estimated by measuring a parameter (e.g., gate or substrate current during the application of hot carrier stress) of the MOS transistor (M1) in the detector (PD1) for a short time and examining previously obtained correlation records between a lifetime and the parameter, to evaluate plasma damage.
