Title: Steering shaft for automobile
Inventor: MAENAKA TOORU
IPC: B62D1/16
Filed: 1980-02-07
Abstract: PURPOSE: To prevent waving phenomenon at the time of steering operation by forming a middle broken angle on the steering shaft using the crossed angle of a rack and a pinion.  
     CONSTITUTION: A steering shaft 15 is composed of a lower part shaft 16 and an upper part shaft 17, and the both shafts are connected with a crossed angly by engagement of a rack 18 and a pinion 19. The housing 20 which surrounds the middle broken connecting part is supported by a steering support 13, and the end parts of the both shafts are borne by the housing 20. The lower end of the lower part shaft 16 is connected through a link mechanism composed of a bell crank 23 which is positioned at a drag link 22 and under the floor panel, and a drag link 24 to a control linkage. Thus, operating force of a steering wheel 25 is converted through a pinion 19 and a rack 18 to the smooth vertical movements of the lower part shaft 16, and the movements are transmitted through the link mechanism to the control linkage.

Title: Apparatus for mounting electronic component
Inventor: SATAKE SHINSUKE
IPC: G01B21/20
Filed: 1985-01-30
Abstract: PURPOSE:To enable automatic division of the suitability about the bending of a printed circuit board without depending on visual inspection or the like, by providing a detecting section for the bending of the printed circuit board. CONSTITUTION:When a printed circuit board 2a is carried into an apparatus from a printed circuit board carry-in section 3, a displacement detection sensor 13 detects the deviation DELTAt1 or DELTAt2 in the height of the center 12 of a mounting base 11 of the printed circuit board 2. The position range is predetermined so as to allow the normal mounting of electronic components 1 on the printed circuit board 2a with a mounting head 5 to be compared with the detected deviation DELTAt1 or DELTAt2. As a result, when the deviation DELTAt1 and DELTAt2 exceeds the allowable value, the bending of the board 2a is determined to be too large for normal mounting and the mounting of electronic component 1 on the board 2a fails. For example, the board 2a is distinguished as defective via a board driving section 6 and a printed circuit board carry-out section 7 and carried out of the equipment. This eliminates visual inspection thereby enabling the automation of an electronic component parts mounting process.

Abstract: PURPOSE:To allow core alignment using a fusion splicing machine of a direct core viewing type so that low-loss connection is executed by removing the front end part of a thin-film coating layer of a carbon system of an optical fiber by thermal decomposition. CONSTITUTION:The coating part 13 of the optical fiber 10 from which the coating part 13 at the terminal is removed to expose the thin-film coating layer 12 is set to an optical fiber holder 2. The front end of the optical fiber is positioned at the center of a pair of electrode rods 3a and 3b facing each other. A voltage is then applied between the discharge electrodes 3a and 3b by a discharge power source 5 by turning on the discharge switch 6a of a discharge controller 6 to generate an arc discharge 4. The front end of the thin-film coating layer 12 is applied with 500 to 1,000 deg.C heat by the discharge heat, by which the front end of the thin-film coating layer 12 is thermally decomposed and removed. The end faces of the exposed bare optical fibers 11 are butted against each other and are axially aligned, thereafter, the end faces are fusion-spliced by the discharge heat in the air. The low-loss connection of the optical fibers is thus executed by using the fusion splicing machine of the direct core viewing type.

Abstract: PURPOSE:To reduce the thermal load to a laser medium and to perform high repeating operation by exciting the solid laser medium of a laser oscillator by semiconductor laser. CONSTITUTION:An AlGaAs type semiconductor laser 1 is subjected to pulse oscillation as an exciting light source and a YAG rod 3 doped with erbium (Er) is irradiated with laser beam in the axial direction thereof through a SELFOC lens 2.

Abstract: PURPOSE: To detect the position of a moving object, by using at least two photoelectric transducers, and finding the change in the photoelectromotive force caused in the photoelectric transducers when the object is moving.  
     CONSTITUTION: When an object 1 moves towards photoelectric trnasducers 3 and 4 from front side, it passes through many states, that is, the state (d) of not reaching either transducer, the state (e) of reaching the transducer 3, the state (f) of reaching the boundary of transducers 3 and 4, the state (g) of reaching the transducer 4, and the state (h) of finally passing both transducers 3 and 4. In each state, the difference Vd in the photoelectromotive force caused in the transducers 3 and 4 has the minimum point (e) and the masimum point (g). Therefore, the positive or not of the direction of the object 1 may be discriminated by the sequence of appearance of the minimum point and maximum point in the time series. Or, when the motion of the object 1 is perfectly periodic, Vd in the time series is also periodic, so that the motion of the object 1 may be distinguished from the other disturbances.

Abstract: PURPOSE:To increase the converging speed by using an orthogonal function for operation of the tap coefficient. CONSTITUTION:The output of an orthogonal function circuit 22 is supplied to a coder 8, and the output of the coder 8 is supplied to a multiplier 19. The multiplier 19 obtains a product of the output and an error signal en obtained at an identifying/deciding part 7 and delivers it to an integrator 9.

Abstract: PURPOSE:To prevent an erroneous display due to an external magnetic field by surrounding a magnetic response part and a display member with a magnetic shield member. CONSTITUTION:An electromagnet 15 and a display member 12 together with a plastic case 11 are surrounded by an iron casing 16. A transparent plastic cover 17 is integrally mounted on the casing 16. A lens-like part 17a is provided on the cover 17 to make the display visible. With this arrangement, the magnetic flux 18 of an external magnetic field is concentrated into the iron casing 16, thereby reducing the effect of the external magnetic field upon a magnetic response part to eliminate an erroneous display and also prevent dust intrusion. When an earth leakage accident happens, an electric current flows through a set coil 14a. The polarity of both poles of a core 13 is reversed and consequently a display member 12 is reversed and then a display 12b shows the occurrence of an accident. The display is kept even after the electric conduction of the coil 14a is stopped. After recovery from an accident, a main circuit is turned in and a coil 14b conducts in the reverse direction to the coil 14a and then the polarity of both poles of the core 13 is reversed, so that the normal display (a) is exposed and the display of an accident is eliminated.
