Title: Window device for observation elevator
Inventor: NAKAMURA YASUHIKO
IPC: B66B11/02
Filed: 1994-03-01
Abstract: PURPOSE:To prevent the cloud of a window and the adhesion of dew respectively by measuring the temperature and the humidity inside and outside a car having an observation window respectively, and energizing the hot wires attached to the glass of the observation window according to the difference in the inside and outside temperature and humidity to heat the glass surface. CONSTITUTION:In an elevator having an observation window, a hot wire 1 to raise the surface temperature of the glass surface is arranged on the glass surface 2 of the observation window of a car. Temperature sensors 3, 5 and humidity sensors 4, 6 are arranged inside and outside the car. A surface temperature sensor 7 is arranged on the glass surface 2. The respectively measured values by the sensors 3-7 are received by a judging device 8, and a judgement is made whether the air inside and outside the car may reach the dew point or not when the air is brought into contact with the glass surface 2. As a result, when a judgement is made that the air reaches the dew point, the power of the hot wires 1 is turned on by a control device 9 to heat the glass surface 2. Thus, the air in the vicinity of the glass surface does not reach the dew point.

Title: Reflow soldering
Inventor: KOBAYASHI MASAICHI
IPC: B23K1/008
Filed: 1988-02-12
Abstract: PURPOSE:To develop self-alignment effect fully and positively and to reduce soldering adjustment to half for melting solder, by superposing vibration to carrier means and by self-aligning a packaged part to a packaging position. CONSTITUTION:Printed wiring boards 1 are carried to a preliminary heating section 2 by a carrier chain 5, heated by infrared rays, further heated at a reflow soldering section 3, exhausted after a fixed time, taken over to a carrier chain 5, and cooled at a cooling section 4. The chain 5 is moved intermittently by rotating a stepping motor 6 at a low rate to apply impulsive forces to wiring boards 1. When solder attains to a melted condition at the reflow soldering section 3, applied vibrations promote self-alignment effect positively. Since vibration impact is not allowed at the cooling section 4, another chain is used to change to the carrier chain 7 and smooth carrying is conducted by driving an alternating current motor 8. Soldering adjustment can be thereby reduced by half.

Abstract: PURPOSE:To contribute to improvement of efficiency at a whole task by a method wherein relative motion speed between a frame and a vehicle at the time of brushing a bon-net face with an upper rotating brush is controlled to be lower than that at the time of brushing a top. CONSTITUTION:Such constitution is made wherein a driving means 7 of relative motion is controlled so that relative motion speed between a frame 2 and a vehicle at the time of brushing the bon-net face of the vehicle with an upper rotating brush 5 is lower than that at the time of brushing a top. As a result, at the time of brushing the bon-net face, relative motion between the frame 2 and the vehicle is possible at a low speed so that even if contaminant such as water scale is tightly attached to the bonnet face the contaminant can be efficiently removed by taking sufficient time in brushing and at the time of brushing the top where the contaminant is relatively easy to remove, the speed is increased for rapid and secure brushing. Therefore difference in efficiency of removing contaminant on both faces is suppressed as much as possible thereby largely contributing to improvement in efficiency at a whole task.
