Title: Cassette loading device
Inventor: ANDO MASAHIRO
IPC: G11B15/675
Filed: 1986-12-12
Abstract: PURPOSE:To prevent the duplex insertion of a cassette by regulating the insertion of a cassette by at least one insertion prohibiting member even if a cassette is inserted by mistaking the length and breadth and making the insertion prohibiting member impossible to turn according to the moving position of a cassette holding member as well. CONSTITUTION:A locking lever 7 is turned in the reverse direction to the arrow mark A direction of a tension spring 4 centering around the F which is the hole penetrating the shaft fitted to the chassis main body 8 of this cassette loading device by the bottom part of a cassette 1 stipulated by the positioning pin 9 locating the cassette 1. The lever 3 preventing the misinsertion of a cassette becomes in the state of being pushed up from the lower part by the turned locking lever 7.

Title: Drive device
Inventor: SEKINE MASAJI
IPC: H02N10/00
Filed: 1985-12-25
Abstract: PURPOSE:To make it possible to facilitate complicated motion of a drive element for a robot or the like by changing the direction of current fed to a thermo- electrical device utilizing a Peltier effect to heat and cool a drive section composed of a shape memory alloy. CONSTITUTION:When switches S2, S3 are closed, and switches S1, S4 are opened, d.c. current I runs from a d.c. source E to ther-moelectric devices M, N, and therefore, a thermal stream Q flows leftward due to a Peltier effect to heat a shape memory alloy A while to cool a shape memory alloy B so that a movable section is shifted to a stationary section (b). When the switches S2, S3 are opened while the switches S1, S4 are closed, a d.c. current in the reverse direction is fed to the thermoelectric elements M, N with the thermal stream flowing rightward to cool the shape memory alloy A which therefore contracts, while to heat the shape memory alloy B which is therefore elongates, thereby the movable section (c) is shifted to a stationary section (a). With the repetition of the above-mentioned operation, the movable part (c) may be reciprocated. Thus, it is possible to easily carry out a low speed motion and a complicated motion.

Title: Master/slave manipulator system
Inventor: SUGIMOTO AKIRA
IPC: G05D3/12
Filed: 1987-11-25
Abstract: PURPOSE: To prevent excessive force from acting on a manipulator and a work object even by a simple unilateral control method by controlling compliance of the manipulator by changing gain of a control means. CONSTITUTION: When confirming that a manipulator contacts with a work object, an operator visually confirms a positional error of the manipulator and the object for the first time, and strongly grips a hollow body 1 of a grasping power detecting device 20 by necessary strength while still closing an opening 2 arranged in one end part of the hollow body 1 by a thumb. Then, an increase in this grasping power is transmitted to a control part through the grasping power detecting device 20. Next, the control part increases this gain according to the size of the grasping power. As a result, the manipulator performs work in a low compliance condition according to the size of the grasping power. Since such operation is performed, desired work can be safely performed without applying excessive force to the manipulator and the work object even by a unilateral control method.

Title: Semiconductor laser
Inventor: ASADA SUSUMU
IPC: H01S5/00
Filed: 1987-11-24
Abstract: PURPOSE:To narrow an outgoing spread angle in the face direction, and to project beams to sections except the in-face direction by tapering a sectional shape along the axis of a pore reaching a striped active layer from the surface at an end section on the active layer side. CONSTITUTION:An active layer 12 is formed into a semiconductor clad layer 11 on a semiconductor substrate 10, and sectional shapes along the axes of pores 14 are formed to a tapered shape. Consequently, since tapered sections 21 in which end sections on the active layer 12 side of the pores 14 are formed to the tapered shape are shaped, emission from the active layer 12 is projected as face-direction outgoing beams 15 besides in-face outgoing beams 13. Since a semiconductor laser 16 can project beams within narrow ranges in the axial direction of the pores, a desired light-receiving section in another face type optical information processing element 17 arranged to an upper section can be irradiated with beams. Said pores 14 can be formed easily by a focussed ion beam device for an AuSiBe liquid metallic ion source.

As for the star projecting plate 20, the optional transmissive pattern is generated by using an electro-optic element which changes the optical characteristics when the electric field is impressed, and in this case, a liquid crystal element is in use.  It is judged by a planetarium controller whether or not the projected fixed star image and the other projected image overlap each other, and fixed star shield information is calculated by the controller, and information on the transmission pattern for the fixed star is corrected so as to shield the transmissive pattern for an optional fixed star.
