Abstract: The tape transport device of a tape recording and/or reproducing apparatus having normal-forward, fast-forward and rewind operating modes in which a tape is transported between supply and take-up reels is provided with fluid couplings in the drives for such reels. Each of the fluid couplings includes a driven member adapted to be rotatably coupled to the respective reel, a rotatable driving member and a body of liquid contacted by the driving and driven members for transmitting a torque therebetween, and the distance between the driving and driven members is varied in response to temperature changes so as to compensate for the effect of such temperature changes on the viscosity of the liquid. The distance between the driving and driven members of the fluid coupling associated with the take-up reel is changed for the normal-forward and fast-forward operating modes, respectively. In the normal-forward operating mode, the driving member of the fluid coupling associated with the supply reel is rotated at a substantially constant rotational speed so that, as the tape is unwound from the supply reel at a constant linear speed, as by the usual capstan and pinch roller, the torque resisting turning of the supply reel varies substantially in inverse proportion to the progressive decrease of the tape wound on the supply reel for maintaining a substantially constant back tension in the tape between the capstan and supply reel.

Abstract: 1425668 Hydraulic couplings SONY CORP 17 Jan 1974 [19 Jan 1973 (2)] 2308/74 Heading F2W [Also in Division G5] A fluid coupling in the drive to the reels of a tape recorder comprises a drum driving member 83 coupled via the fluid in cylindrical cavity 85 within the drum to a disc driven member 84 connected to drive shaft 80. The shaft rests on a bimetallic plate 94 in the cavity base which acts during increase in temperature to move the driven member upwards to reduce the distance between it and the roof of the cavity in the driving member thus compensating the reduction in torque transmission due to the drop in the viscosity of the fluid. In a second arrangement Fig. 9 (not shown) the bimetallic plate is dispensed with and the driven member is formed of bimetallic material. In the Fig. 10 arrangement plunger 114 is vertically displaced downwards by screw jack 119 when the recorder is changed from normal to fast forward mode thus the take up reel drive shaft 96 is lowered by arm 110 thereby increasing the distance between the driven disc 102 and the roof of the cavity in the driving member. This movement decreases the coupling to reduce the torque transmission to protect the tape when the supply reel completely unwinds. In this arrangement the arm 110 can be of bimetallic material.

Abstract: PURPOSE: To provide an optical type detecting and measuring apparatus and a method therefor which can increase the freedom of designing and facilitates the standardization while improving the productivity, and is useful for maintenance and inspection service or the like. CONSTITUTION: A plurality of plane reflection mirrors 1a-1e are arranged so that parallel beam light 5 radiated from a projection part 3 enters a photodetecting section 4 following a star path drawn in a star and a polygonal detection area is formed inside the center part surrounded by the star path. An object 16 to be detected is arranged in the detection area to be measured.

Abstract: PURPOSE:To connect leads with high reliability and high yield without applying mechanical strain such as ultrasonic strain, etc., thermal strain by depositing special first, second metal layers, and forming a solid solution alloy layer on a boundary between both the layers to form a bonding pad. CONSTITUTION:A first metal layer 11 made of Al series and a second metal layer 12 made of metal series of one type or more selected from Au, Ag, Cu, Sn, Sn-Pb alloy are continuously deposited on a semiconductor substrate 1 in a nonoxidative atmosphere. Then, it is heat-treated at a temperature lower than an eutectic temperature of both the layers 11, 12 to form a solid solution alloy layer on a boundary between both the layers 1 and 2, thereby forming a bonding pad 15. For example, the layers 11, 12 are continuously deposited by vapor-depositing, etc., on the substrate 1 in a nonoxidative atmosphere, then selectively irradiated with a laser light to form a solid solution alloy layer of both the metal layers.

Abstract: PURPOSE:To secure such braking force as stronger than the force that is made to act on a main driving lever, by turning both of the main driving lever and a driven level round centering on a first shaft, while turning the driven lever centering on a second shaft after a friction member comes into contact with a rotor. CONSTITUTION:Usually, a friction member 15 gives a rotor 11 small braking force through a spring 16. When a lever 22 is driven to the right, the lever 22 makes contact with a main driving lever 13, rotating both of the main driving lever 13 and a driven lever 18 clockwise centering on a first shaft 12 against a spring 16, and a friction member 20 comes into contact with a rotor 11 as soon as the friction member 15 separates from the rotor 11. And, when such force that goes beyond the specified value is imposed on a limiter spring 22, it extends in length and the main driving lever 13 rotates centering on the first shaft 12, while the driven lever 18 moves in its turning center and rotates centering on a second shaft 17, so that the friction member 20 is forcibly pressed to the rotor 11 and large braking force is thus given there.
