  • Patent number: 10408261
    Abstract: A linear motion guide unit restrains fluctuations in sliding friction and generation of heat by correcting the postures of rollers having been inclined in a no-load area such that their axes become orthogonal to a guide surface of a carriage to thereby introduce the rollers in proper postures into a load area. A retainer plate of the guide unit has a guide surface for guiding end surfaces of the rollers and has protrusions protruding from the guide surface at its opposite end portions facing crownings of the carriage. The rollers rolling from a turnaround passage to a load-carrying race are pressed by the protrusions toward the guide surface of the carriage so as to be arrayed in such a posture that the axes of the rollers become orthogonal to the guide surface on the inlet side of the crowning of the carriage, whereby the occurrence of roller skew is prevented.

  • Patent number: 10378581
    Abstract: In the linear motion guide unit, a retainer plate for retaining rolling elements, or rollers, is prevented from deformation so as to smoothly guide the rollers. The retainer plate is composed of a retainer member, frame members fitted into respective through holes formed in the retainer member, and a fixing member disposed in a longitudinally extending recess of the retainer member. The frame members form a predetermined gap between the fixing member and a carriage. Tightening forces of fastening bolts are not applied to the retainer member, thereby avoiding deformation of the retainer member.

  • Patent number: 10291443
    Abstract: A communication method for a serial communications unit converts reception serial data into reception parallel data, stores the reception parallel data in a memory unit, and calculates a reception delay time of a reception start timing at which reception of packets is started. In addition, the reception parallel data which is stored in the memory unit is read out, and transmission parallel data, in which a transmission delay time of a transmission start timing at which transmission of packets is started is controlled so that a delay time from the reception start timing of packets and until transmission of packets is started is made constant, is output in synchronism with a transmission parallel clock pulse signal, and the output transmission parallel data is converted into transmission serial data and then is transmitted.

  • Publication number: 20190066846
    Abstract: The present invention relates to a method for assisting recurrence risk prediction for hepatocellular carcinoma patients. The method comprises measuring glypican 3 (GPC3) peptide recognized by both a first monoclonal antibody and a second monoclonal antibody in a blood sample of a hepatocellular carcinoma patient, by contacting the sample with the first monoclonal antibody that recognizes a peptide having an amino acid sequence in the N-terminal side of GPC3 and the second monoclonal antibody that recognizes a peptide having an amino acid sequence in the C-terminal side of GPC3, and detecting the complex comprising GPC3 peptide, the first antibody and the second antibody.

  • Patent number: 9518587
    Abstract: An air compressor comprising: a tank (50), a compression mechanism (30), a motor (5) and a control circuit (7). The control circuit (7) includes a CPU (70) and a storing unit (74) which stores a control program, the compressor operation history and a plurality of operation modes. Each of the operation modes is defined by two setting values: a reference restart pressure value and a motor rotational speed value, at least one of these values being different from among the plurality of modes. The control circuit (7) executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the pressure in the tank with the reference restart pressure and rotates the motor at the rotational speed of the target mode. The control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the compressor operation history.

  • Publication number: 20160239443
    Abstract: A direct memory access (DMA) controller issues a standby request a predetermined period of time before data transfer having a high priority starts and prohibits data transfer having a low priority in advance, and thus data transfer having a high priority can generate a transfer cycle from a data transfer start point in time without waiting. Accordingly, a transfer time is reduced, a variation in the transfer time is reduced, and thus a real time property of a system is improved.
