Title: Manufacture of heat resistant braided wire
Inventor: SUYAMA YOSHIYUKI
IPC: H01B3/46
Filed: 1993-08-31
Abstract: PURPOSE:To manufacture a heat resistant braided electric wire with a good yield by continuously applying silicon wax on a braided coating after forming the braided coating by glass fiber or the like on the electric wire. CONSTITUTION:An electric wire A, in which silicon rubber is extruded onto a conductor of a copper wire or the like so as to coat it, is supplied from a bobbin 8 to a braiding device 1, and glass fiber thread B is braided on the electric wire A, so that a braided electric wire C is formed. The electric wire C is fed to a silicon varnish treatment bath 3 by a feeding roll 2, and silicon varnish is applied on the braided wire C at 0.020-0.035g/cm<2>. In this case, the nonvolatile matter concentration is set to 55-70weight%, so that defects such as a kink (core wire bending) due to a shortage of the concentration, broken thread, extended rubber are prevented, while the viscosity of the silicon varnish is regulated to 1000-5000cp so that uneven adhesion, which is caused by high viscosity due to excessively high concentration, of the silicon varnish is prevented. In a restrictor 4, excessively adhering silicon varnish is eliminated from the braided electric wire C, on which the silicon varnish is stuck, and then, the braided electric wire C is wound up by a winding device 7 after heating and hardening the varnish by a heater 5.

Title: Voltage detector of piezoelectric actuator
Inventor: TSUTSUI OSAMU
IPC: H02N2/00
Filed: 1990-09-11
Abstract: PURPOSE:To reduce power consumption while a piezoelectric actuator is charged and improve a charging efficiency and, further, maintain a charging voltage at a target voltage for a long time while the charge of the piezoelectric actuator is held by a method wherein a semiconductor device which is closed only when the charging voltage is detected by a voltage detecting means is provided between first and second resistors. CONSTITUTION:When the charging voltage V1 of a piezoelectric actuator PA is detected, a semiconductor device Q is closed and the divided voltage V2 of a second resistor r2 is detected by a voltage detecting means V. As, generally speaking, the voltage drop VQ (for instance 1V) of the semiconductor device Q is substantially smaller than the charging voltage V1 (for instance 1000V), it can be neglected. When the voltage detection is not performed by the voltage detecting means V, the semiconductor device Q is opened. Therefore, while the piezoelectric actuator PA is charged, the charge of the piezoelectric actuator PA is hardly discharged through the semiconductor device Q, so that power consumption can be reduced and charging efficiency can be improved.

Abstract: PURPOSE:To reproduce sound at a high or low speed without changing the level, tone quality and length of sound and with no deterioration in sound quality, by making use of the periodical properties of the sound signal to multiply plural cycle waveforms by the weight coefficient for synthesization. CONSTITUTION:The sound signal given from a telephone is converted into a digital signal through an exchange channel 10 and stored in a magnetic disk device 15 via an interface circuit 13 and a buffer memory circuit 14. The circuit 14 collects the continuous sound signals for each block to secure the input/output of DMA mode to the device 15.

Title: Turbo molecular pump
Inventor: MACHIDA SHIGERU
IPC: F04D19/04
Filed: 1983-12-23
Abstract: PURPOSE:To prevent the serious damage of the turbo molecular pump by a method wherein a protecting means, constituted so as to prevent a rotating body from contacting with other stationary parts during a short period of time wherein the phenomenon of core deviation or levitation of the rotating body due to the leakage of atmosphere or the like is generated, is provided in the pump. CONSTITUTION:Permanent magnets 20A, 20B, forming a permanent magnet magnetic bearing 20, are fixed to the lower end of a rotor 12 and the support member 6 of the rotating body 5 opposing to the lower end of the rotor 12. The rotating body 5 is constituted so as to have the support point thereof at a pivot type sliding bearing 15 to permit the stabilized high-speed operation of the system of the rotating body. In case of an abnormal time, wherein atmospheric pressure acts on a delivery port 8, the rotating body 5 leviates instantaneously and a pivot shaft 15a separates from a bearing body 15b minutely. At this time, the center deviation preventing member 21, arranged at the inside of a tubular member 19 fixed to the support member 6, functions and prevents the excessive center deviation of the pivot shaft 15a. According to this method, the pivot shaft 15a seats again on the bearing body 15b under a normal condition and the rotating body 5 may be operated without being subjected to any damage.

Title: Reflow welding machine
Inventor: SAKURAI HIDETOSHI
IPC: H01R43/02
Filed: 1988-09-26
Abstract: PURPOSE:To make it easier to solder a board to a cable and completely remove solder balls that are generated at the soldering by melting solder on the board and absorbing air injected. CONSTITUTION:A heating chip 15-1 that has been heated to the solder-melting temperature of the main body 15 of a welding machine is caused to fall down to press sheet-shaped solder 3, so that the solder 3 is melted and allowed to flow through both the connection pattern 1-2 of an insulting panel 1-1 and the core with 2-1 of a cable 2, while one part of the solder 3 converts into ball shape because of the surface tension and then splashes onto the surface of the insulating panel 1-1. At this time a sensor 15-3 detects the state of the solder 3 in which it is pressed by the pressing face of the chip 15-1, so that a control portion 19 delivers a command to release a valve 16 to spray from an injection nozzle 17 high-pressure air, which is absorbed by an absorbing nozzle 18 at the same time. In this way, the solder 3 allowed to flow through both the connection pattern 1-2 and the core wire 2-1 remains because of its adhesion, while one part of the solder 3 that is melted and splashes onto the surface of the plate 1-1 is blown off by the high-pressure air and then absorbed by the nozzle 18.
