Title: Multirotational encoder
Inventor: UEDA TOSHITSUGU
IPC: G01B7/00
Filed: 1986-05-06
Abstract: PURPOSE:To obtain a highly accurate and absolute measuring output even when a power supply is cut off during a measurement by combining a highly accurate absolute encoder and a revolution detector utilizing a magnetic bubble element. CONSTITUTION:Two slit rows 21 with different pitches, for example, are provided on a code plate 2. A slit reader 3 is constituted by an optical sensor array and the absolute rotational angle of the plate 2 is measured from the phase difference and the amplitude of alternating signals obtained from the reader 3 in accordance with the positions of the rows 21. Therefore, a revolving magnetic field is applied to a magnetic bubble element 5 when a permanent magnet 4 is rotated with the plate 2 and, if the magnet 4 has two poles, the magnetic bubbles in the element 5 is moved by one step on the transfer pattern of the element 6 when the plate 2 is rotated by one revolution. Accordingly, when the positions of the magnetic bubbles on the transfer pattern are detected, the number of revolution of the plate 2 can be known and the rotational angle of the shaft 1 is calculated (6). When the revolving magnetic field is applied to the element 5, even if a power supply is cut off, the magnetic bubbles are transferred and an always absolute measurement can be performed.

Title: Crossover cutting device
Inventor: NAKAMURA KATSUMI
IPC: B65H54/86
Filed: 1990-04-19
Abstract: PURPOSE:To dispense with the removal of a crossover in the post-process by providing an arm pressing the crossover at the intermediate section between a crossover holder and the crossover and near a terminal in a cutting device of the crossover remaining between the winding work of a rotary type winding machine and a wound work. CONSTITUTION:When a drive shaft 31 is rotated, the tip section 37 of the first arm 35 presses a crossover 20 at the intermediate section between the fixed point of a crossover holder 23 and a work W. The crossover 20 is stretched into a nearly L-shape, and proper tension is applied. The tip of the second arm 36 located at a relatively lagged position further presses the crossover 20. Since the tip of the second arm 36 presses the crossover 20 near the pole of a terminal 6, the crossover 20 is strongly pulled in the direction with a very small angle with the center line of the work W. Stress is concentrated at the edge of the terminal 6, and the crossover 20 is surely ruptured at this position. Since the arm length of the second arm 36 is long, the peripheral velocity of the tip section is relatively large, and the crossover 20 can be surely cut from this viewpoint too.

Abstract: PURPOSE:To increase the specified proportional relation on the momentary turning center of a wheel as well as to secure a sufficient anti-dive effect by feeding or exhausting oil to or from the elastic bush, installed in a body side support part, of a suspension arm, at the time of braking a vehicle. CONSTITUTION:If a car body is made to nose-dive by inertial force at time of braking, each of upper and lower arms 2 and 3 is rotated upward each centering on rocker shafts S1 and S2 at the body side. Accordingly, the piston rod 15b, connected to the lower arm 3, of a hydraulic cylinder 15 as an oil feed- exhaust device goes up in the cylinder body 15a. In consequence, oil is fed to each oil chamber of respective elastic bushes 6-9 interconnected to an upper oil chamber 15d of the cylinder body 15a, while oil is exhausted from each oil chamber of these elastic bushes 6-9 interconnected to a lower oil chamber 15e. With this constitution, the ratio of road level of the momentary turning center in the wheel to longitudinal length from a wheel grounding point is increased.

Title: Voltage application method for scanning circuit for photo diode array
Inventor: AKAGI MASANORI
IPC: H04N1/19
Filed: 1990-04-19
Abstract: PURPOSE:To increase the maximum value of a signal current outputted from a photo diode array by applying a positive voltage to a cathode of a 2nd diode when a sawtooth voltage is applied to a 1st diode so as to output a scanning voltage for the photo diode from the anode of the 2nd diode. CONSTITUTION:When a photo diode array 2 is scanned, a prescribed positive bias voltage VB is applied to a 2nd common line 5. Then a sawtooth voltage Vdr is applied to an anode of a 1st diode DW1. When the voltage Vdr rises, the cathode side output of the diode DW1 rises and the anode voltage of a 2nd diode DT1, that is, the scanning voltage is gradually increased. In this case, since a prescribed positive bias voltage VB is applied to the cathode of the diode DT1, the anode voltage of the diode DT1 is not saturated even when it exceeds a reference voltage of the diode DT1. Thus, the maximum value of a signal current Iout is increased.

Title: Bonding tool
Inventor: SUZUKI TAKAYUKI
IPC: H01L21/60
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To improve thermal fatigue service life of a wedge bonding joint by setting the groove of a tool with the groove for wedge bonding into chevron- shape, and by setting the opening angle of the lower end of the tool larger than that of the groove. SOLUTION: In a bonding tool 1, a chevron-shape groove 2 is provided. An opening angle θ2 of a lower end 3 of the tool is set larger than an opening angle θ1 of the groove. When the bonding tool is used, pressure is applied to a position near left and right ends, without applying the pressure to the top part of a wire for accelerating the deformation of the sides of the left and right ends of the wire, and the surface of the wire is restricted by the groove 2 for deforming and is pinched between the lower end 3 and a material to be jointed for jointing. The angle of the joint end of the material to be jointed and a wire 4 becomes larger than the angle being formed by the chevron groove. The smaller the angle of the end part is, the larger the stress concentration of the joint end becomes.  For example, when the angle of the joint end is set to 0, cracks will result, and the stress concentration is maximized. By using the bonding tool, the angle of the joint end is set to an obtuse angle for reducing the stress concentration.
