Title: Progressing wave type semiconductor laser amplifier
Inventor: SAITO TADASHI
IPC: H01S5/00
Filed: 1989-06-12
Abstract: PURPOSE:To make it possible to maintain a low operating current density, a low polarization surface dependence and high power and low noise at the same time by providing an optical wave guide layer which has a band gap larger than that of an active layer at least on one side of said active layer which tends to increase. CONSTITUTION:An optical wave guide layer 2 having a band gap larger that of an active layer 1 is provided at least on one side of the active layer 2 which tends to increase. In this manner, the optical wave guide layer 2 is provided at least on one side of the active layer 1. The installation of the wave guide layer 2 make it possible to confine light without increasing the thickness of the active layer 1. Since there is no need to increase the thickness of the active layer 1, the current density can not be increased even if an attempt is made to increase a carrier density. Furthermore, this construction can reduce the thickness of the active layer 1. It is, therefore, possible to obtain high power and low noise, maintaining a low operating current density and low polarization surface dependence as well.

Abstract: PURPOSE:To make it possible to conduct teaching operation simply without any damage to a work by providing a pushing mechanism for pushing out the work at a hand. CONSTITUTION:A work 8 is transferred to the portion of an object (guide pin) 15 by gripping the same by means of the chucking mechanism 9 of a hand 7. Later, the chucking mechanism 9 conducts releasing operation for itself and also the work 8 is pushed out by a pushing mechanism 17 provided at the hand 7 to move the work 8 along an object 15 without any damage to the work 8 and its final positioning is carried out. Thus, since the final positioning for the work 8 is conducted by the operation of the pushing mechanism 17 without regard to the motion of the whole robot, teaching operation can be simplified and shortened.

Title: Optical disk recording/reproducing method and optical disk device
Inventor: KUSANO TAIZO
IPC: G11B7/085
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To attain high speed access and to reduce power consumption by controlling in prescribed combination of a constant number of rotation (CAV) control, a constant linear velocity(CLV) control so as to minimize the change in the number of rotations of a spindle motor when a reproducing position is changed. SOLUTION: An optical disk 1 is divided to areas where regenerative synchronous clocks are different successively from the inside to the outside. Then, unless the regenerative synchronous clocks by a regenerative signal detector 4 and a synchronous clock generator 9 is separated from the synchronous clock decided in the area by a prescribed value or above, the spindle motor 7 is rotated at the fixed number of rotation corresponding to the area through a disk rotation controller 15 having a revolution commander 13, etc., and the disk 1 is CAV controlled. Then, when the reproducing position comes near to a required track of a required area, the control is switched to the CLV control, and then, the change in the number of rotations of the spindle motor 7 is minimized when the reproducing position is changed. Thus, the high speed access and the low power consumption are made compatible.

Title: Condenser provided with group of horizontal heat transfer pipes
Inventor: MURATA KEIJI
IPC: F28F1/12
Filed: 1981-09-24
Abstract: PURPOSE:To make it possible to increase the heat transfer accelerating effect of the lower stage heat transfer pipe by a method wherein in the condenser provided with the group of multistage horizontal heat transfer pipes, the sectional area of the grooves formed on each of the heat transfer pipes in the flow direction of air, the sectional area of the space between the fins attached to the pipe or the sectional area of the space between the wires attached to the pipe, is increased the more the stage of the  pipe group is lower. CONSTITUTION:The pitch of the grooves 6 formed on the lower grooved heat transfer pipe 5 of the group of horizontal heat transfer pipes of the condenser 3 is made larger than that of the grooves formed on the upper heat transfer pipe to thereby increase the sectional area of the groove 6. Likewise, the sectional area of the space between the fins attached to the finned heat transfer pipe or the sectional area of the space between the wires attached to the wired heat transfer pipe is increased as the pipe is installed  at the lower stage. With the above structure, even the grooves on the lower stage heat  transfer pipe are not completely filled with a condensing liquid and the accelerating effect for heat transfer of the pipe is not lost. Accordingly, it is possible to make the  body of the condenser compact and to reduce the manufacturing cost thereof.

Abstract: PURPOSE:To prevent the decrease in the yield of products occurring in the defective appearance of coating and produce electrodes of stable quality by using water glass of specific temp. as a binder for a coating material flux in producing the coated electrode. CONSTITUTION:In the production of a coated electrode, more particularly in the production of a low hydrogen type electrode consisting essentially of carbonate such as CaCO3, MgCO3 or the like, the water glass of controlled temp. to 10-20 deg.C range is used as a binder for a compounded fluz when coating said flux.
