Title: Spiral lithium battery
Inventor: NAKADA HIROYUKI
IPC: H01M6/16
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To increase the safety of a spiral lithium battery, having an electrode group wherein belt-like positive and negative electrodes are spirally wound via separators. SOLUTION: Separators 7 are laminaters composed of a nonwoven fabric: having width wider than that of any one electrode having wider width out of positive and negative electrodes 5 and 6, and a micro porous film: having width wider than that of the unwoven fabric. These separators 7 are wound together with the positive and negative electrodes 5 and 6, to contract a spare length end part in the width direction of the separators 7, to coat the positive and negative electrodes 5 and 6, thereby insulating them. This can compensate the defect of the micro porous film, the easiness of damage, by the nonwoven fabric.

Title: Control for substrate processing device and substrate transferring mechanism
Inventor: KAMIYAMA TSUTOMU
IPC: H01L21/30
Filed: 1993-04-15
Abstract: PURPOSE:To provide a substrate processing device which prevents the time loss and spatial loss due to the receiving/delivery of a processed substrate and secures the high operation efficiency of a substrate transferring mechanism. CONSTITUTION:Processing parts 11, 18, etc., are arranged along an annular orbit 110. Two substrate transport robots 150a and 150b carry out the transport of a processed substrate 2 and the take-in/out of the processed substrate into each processing part, through the circular shift in the counterclockwise direction on the annular obit. The substrate transport robot rotates to correct the twist of the electricity feeding wires 121a and 121b in one turn on the annular orbit. Accordingly, the ncessity o receiving and delivery of the processed substrate between the substrate transport robots is obviated. Further, since the substrate transport robot can return to the initial position without passing through a going passage, the operation efficiency of the substrate transport robot is improved. Because of the rotation of the substrate transport robot, the twist of the electricity feeding wire is prevented, and the continuous operation is enabled.

IPC: F16D65/14
Filed: 1982-07-02
Abstract: PURPOSE:To prevent chattering or sliding noise by equipping the guide to be fastened to the disc by bolt with spline teeth having a similar form to the ring. CONSTITUTION:When a coil 1 is energized, a disc 4 is attracted by the coil 1 to cause application of brakes. When energization is released, the disc 4 separates from a friction plate 3 owing to the force of a return spring 10 to stand free for rotation.

Title: Ultrasonic wave type displacement detector
Inventor: YAMADA IZUMI
IPC: G21C17/00
Filed: 1982-07-02
Abstract: PURPOSE:To accelerate the response of the titled detector, by a method wherein displacement is measured by utilizing such a fact that the interval of an echo from the rotary axis of intermittently generated ultrasonic waves is modulated by vibration displacement to shorten an intermittent time interval. CONSTITUTION:Ultrasonic waves are projected to a rotary axis by the output signal 101 of an oscillator 20 and the echo thereof is obtained as the output 102 of an ultrasonic receiver 11. The time width of the delay signal 104 of the echo arrival timing signal obtained by the previous timing and an echo arrival timing signal 103 is converted to a voltage signal 105. A time voltage converter 60 generates a positive or a negative signal by the before and behind relation in generation of the echo arrival timing signal 103 and the delay signal 104. The signal 105 is a vibration speed signal and is converted to a displacement signal by an integrator 70. Because the speed signal 105 is multiplied by a sound speed at this time, the displacement signal compensated in a temp. is obtained. In this case, a material having sufficient damping effect is used with respect to an ultrasonic wave transmitting and receiving elements 10, 11 and the generating timing interval of ultrasonic waves is made short to enable the measurement of displacement in sufficiently rapid response.
