Title: Chain block provided with self-braking device
Inventor: ASANO MASATOSHI
IPC: B66D3/16
Filed: 1988-12-12
Abstract: PURPOSE:To decrease the generation of a metallic sound at the time of operation and to reduce noise by producing the rotating force in the opposite direction to the load direction, with the mesh point of a differential planetary gear with a sun gear as the cardinal points by the rotating force in the load direction of the differential planetary gear to self-brake the differential gear. CONSTITUTION:When a load is applied to the lower hook of a load chain, a load gear 24 is pressed and meshed with the large-diameter tooth portion 18 of a differential planetary gear 16 and a center floating tooth portion 20 while backlash is eliminated, to force the large-diameter tooth portion 18 to rotate in the load direction, so that the rotating force in the same direction is also produced in a small-diameter tooth portion 17. Accordingly, the differential planetary gear 16 is about to rotate in the reverse load direction, with the mesh point with the sun gear 12 as cardinal points and is self-braked at one point within the load side radius region of the sun gear 12. When a manual chain is operated in such a condition, the center floating gear 20 is rotated to push up load quietly. In this arrangement, a click and a ratchet are not used for braking load, so that the generation of a metallic sound is decreased.

Title: Drive device for ink jet head
Inventor: YASUTOMI HIDEO
IPC: B41J2/485
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To improve a print quality by providing a first and a second voltage application means with different dot size control methods for applying a pulse voltage of a specified form to a piezoelectric element when applying, for printing a dot of a desired size selected from among dots of varying size. SOLUTION: A voltage value is controlled in a small diameter area as shown by (A) to change a dot gradation. On the other hand, in a large diameter area as shown by (B), a pulse frequency control is performed to change a dot diameter. The voltage value control means controlling the volume of a discharged ink while time in which a pulse voltage is applied is the same. On the other hand, the pulse frequency control to be performed in the large diameter area is such that a pulse is output 5 times at an interval of 10μsec, between the fall and the rise of the pulse in the gradation 10, twice in the gradation 7, three times in the gradation 8 and 4 times in the gradation 9. To print a dot of a large size, a high voltage need not be applied to a piezoelectric element.

Abstract: PURPOSE:To achieve junction without using any flux at the time of mounting a parts by allowing two kinds of metals A and B, where a melting point lowers to a temperature below room temperature in the case of formation of an alloy, to be subjected to the formation of fluxing alloy at room temperature and then cooling to operating temperature of parts. CONSTITUTION:An Au9 is deposited at both terminal regions of a silicon chip 7 and an alumina substrate 8 up to thickness of 1000Angstrom  and then In10 is deposited to a thickness of 100mu on it. Then, a Ga piece 11 which is of the same size and thickness as the deposited In is placed on the In10 of terminal region of the alumina substrate 8. In this case, the total amount of the deposited In10 is equal to approximately 17% in capacity ration of the total amount of a Ga piece 11 and the In10 and approximately 24% in weight ratio and it is fluxing state at 20 deg.C in the case of alloy state. Thus, the In10 and Ga11 are put into contact, a pressure of 20-100g/cm<2> is applied to. Then, the In10 and the Ga11 are fused together, thus resulting in an InGa alloy 12. If it is left at 0 deg.C for five minutes, it is coagulated and fusing joining is completed.
