Title: Reflow plated member and its production
Inventor: SUZUKI SATOSHI
IPC: C25D3/60
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide the member having excellent solderability, heat resistance and wear resistance, and further, small nonuniformity in section and also to provide the production of the member. SOLUTION: In this member, each of the surfaces of a base material 1 at least the surfaces of which consist of Cu or a Cu alloy is coated with a reflow plated layer 2 consisting of Sn or an Sn alloy and crystal grains in the inner layer part 2a of the reflow plated layer 2 have particle size smaller than that of the crystal grains in the surface layer part 2b. At the time of subjecting the reflow plated layer 2 formed on each of the surfaces of the base material 1 by using an electroplating method to reflow treatment, the reflow treatment is performed by allowing the base material 1 to travel at a traveling speed equivalent to 80 to 96% of the lowest traveling speed at the time of not melting the plated layer 2. In particular, resolidification of the molten plated layer 2 within 0.5sec is effective in reducing nonuniformity in section of the member produced.

Title: Feed roller in peeling machine
Inventor: NISHIO KIYOSHI
IPC: B23B13/00
Filed: 1980-01-24
Abstract: PURPOSE: To feed a workpiece to a spindle head while capability of centering is continuously maintained, by simultaneously moving a pair of upper and lower rollers up and down by an equal distance in response to the varying outside diameter of the workpiece.  
     CONSTITUTION: Racks 22, 23 are arranged on moving members 7, 8 so that the racks are opposed to each other. A free rotary pinion, whose center has the same height as that of a workpiece which is fed while pinched between a pair of rollers 9, 10, is engaged between the teeth of the racks 22, 23. For that reason, the workpiece is surely pinched and fed by the pair of rollers 9, 10 even if the outside diameter of the workpiece varies. This results in continuously maintained capability of centering the workpiece.

Filed: 1995-01-23
Abstract: PURPOSE: To predict the sensitivity to a medicine by measuring the genotype of vitamin D-bound protein, and correlating it with the reactivity to the vitamin D medicine and the therapeutic effect. CONSTITUTION: In diseases related to the adjustment of Ca metabolism which is one of the actions of vitamin D medicines, a vitamin D3 medicine is orally administered to multiple patients subject to osteoporosis, for example, the bone density of each patient after 3-6 months is compared with the initial bone density, and the change ratio of the bone density is obtained. Blood is collected, and the genotype (the group specific component combined in the bone forming process: GC) of vitamin D-bound protein of each patient is measured. When the bone density change ratio and the DBP genotype are correlated, it is found that the GC-2 type patient has the highest sensitivity in the therapy of osteoporosis via the administration of vitamin D medicines.  When the DBP genotype and the reactivity to vitamin medicines are correlated and high- sensitivity patients and low-sensitivity patients are classified in other diseases, a useless therapy can be avoided.

Abstract: PROBLEM TO BE SOLVED: To perform a disk discrimination which is to be finished in a short time with a relatively smiple constitution by moving an optical pickup in a direction traversing tracks of a disk in a state in which the disk is irradiated with a light beam and measuring the number of tracks from the ripple component of a read out high frequency signal to discriminate the kind of the optical disk in accordance with the measured value. SOLUTION: The track pitch and the maximim eccentric quantity of a CD disk are respectively 1.6 μm, ±70 μm and the track pitch and the maximum eccentic quantity of a DVD disk are respectively 0.7 #×m, ±100 μm. When a disk 100 is loaded in a disk reproducing device, the disk is made to be revolved by being applied with a focusing servo. Then, a pickup 110 is moved by a fixed distance in a direction traversing tracks of the disk. Moreover, the number of tracks is known by monitering the read out signal, that is, the high frequency ripple (RERP) signal. Since track pitches are different in the CD disk and the DVD disk, the number of tracks of the DVD disk is larger as compared with that of the CD dsik and, thus, the kind of the the disk 100 loaded in the device is discriminated from this difference.
