摘要： PROBLEM TO BE SOLVED: To prevent outriggers from being left accommodated whereby a danger of tumbling at running up the stairs is eliminated. SOLUTION: Stairs sensing means 10f and 10r sense that there are stairs ahead in the advancing direction of a running device, while means 9f and 9r sense that outriggers 5f and 5r are in the overhung position, and an automatic controlling mechanism stops the running or emits an alarm unless the outriggers 5f and 5r are set overhanging in the case where stairs are sensed while the running device is in running, and thereby a danger due to the operator's missing the carefulness can be precluded properly.

摘要： PURPOSE:To provide easier manufacture of GaAs wafer with precision and less amount of warp by mixing a grinding liquid incl. abrasive grains for lapping with an etching liquid having effect to dissolve GaAs chemically between the upper and lower surface reference boards. CONSTITUTION:Each GaAs wafer is nipped by an upper and a lower surface reference board for lapping which operate at different revolving speeds, and both sides of the ware are lapped simultaneously. The processing distortion layer generated at the surface of the GaAs wafer in the course of said lapping operation is dissolved by the etching liquid contained in the grinding liquid while it serves grinding with abrasive grains contained therein, and then is removed to relieve stresses at the surface of wafer, which should contribute to reduction of a warp otherwise generated there. At this time, the ratio of the mechanical grinding speed by the abrasive grains for lapping to the chemical dissolution speed by etching liquid shall preferably the approximately ten to one.

摘要： PURPOSE:To provide surface printing method and apparatus which enable surface printing of a clad wire surface always at a fixed concentration with the clad wire surface being kept to have fins of a shape conforming to the specification, without squeezing the fins, and without being influenced by the size of the wire. CONSTITUTION:Fins are formed on a clad surface of a conductor 2 delivered via a delivery device 1 through operation of an extruder 6 having a nipple 3 and a fin-forming groove equipped rotary die 4 while the rotary die 4 is being moved by an external rotation-drive means 5. An arm 13 for rotating a supporting rod 12 of a printing roller 8 is moved up and down, through operation of an air cylinder 9, in response to a signal from a limit switch operating through rotation of a rotating or driving shaft of the rotation-drive means 5. The printing roller 8 is thereby moved in such a manner as to skip over the fins, thereby printing onto the clad wire surface. After printing, the wire is caused to pass through a crosslinkage and cooling section 10 located after the printing roller, and is taken up onto a take-up roller 11.

摘要： PURPOSE:To change speed smoothly by providing a normal/reverse change-over switch which switches the polarity of the voltage of a motor and a speed change-over switch which varies the value of the voltage by stages at a device. CONSTITUTION:A +voltage or a -voltage is selected by the normal/reverse change-over switch 8, and voltages from low to high are set by variable resistors 10, 11, and 12. Those voltages and a zero voltage are selected by the speed change-over switch 9, and they are inputted to a servo amplifier 13, then, a servo motor 5 is driven. At this time, the speed change-over switch 9 repeats the switching of the voltage in sequence of zero low middle high middle low according to a time set at a timer, and the normal/reverse change-over switch 8 is switched to an opposite side while the speed change-over switch 9 selects the zero voltage. In such a way, the switching of the voltage in sequence of zero low middle high middle ... according to a preset time is repeated both for the +voltage and the -voltage. As a result, the rotating speed of a dies is changed in four stages both at a +voltage side and a -voltage side, which performs speed change smoothly.

摘要： PURPOSE:To enable adhering, fixing, and removing a wafer in a short time and by a simple method without deteriorating a holding jig, by fixing the water to a transparent plate with a film with viscous bond applied on both surfaces thereof interposed therebetween and removing said wafer by hardening said viscous bond by applying ultraviolet rays thereto after its processing. CONSTITUTION:A transparent plate 4 is used as a holding jig in processing a semiconductor wafer 1. The back of a transparent film 5 with viscous bond 6 and 6' applied on both surfaces thereof is adhered on said plate 4, and the semiconductor wafer 1 is fixed by adhering on the face of said film 5 and processed. After processing, ultraviolet rays are applied to harden the viscous bond 6 and 6' and decrease their adhesion, and the semiconductor wafer 1 is removed from the holding jig. If, for example, the viscous bond 6 is made more adhesive than the viscous bond 6' by making the decreases of the adhesions of the viscous bond 6 and 6' after applying ultraviolet rays different from each other, the film 5 can be removed from the plate 4 and then the wafer 1 from the film to facilitate the removal work.

摘要： PROBLEM TO BE SOLVED: To detect a height position of gravity before a running device advances onto stairs to enable the safe transportation by calculating a position of gravity in a bottom face of a loading part from outputs output from a plurality of weight detectors provided in the loading part of the running device and measuring a travel amount of the position of gravity when the loading part is inclined to calculate the height position of gravity. SOLUTION: A loading part 5 is provided in a car body frame part 1 through weight detectors 7 (7a to 7d) provided at four corners of a bottom part thereof to calculate where a position of gravity of weight of the loading part is on a bottom face of the loading part based on the results of measurement of each weight detector 7. Moreover, with respect to the position of gravity in a bottom part of the loading part, a height of gravity is calculated by measuring a travel amount of the position of gravity and an angle of inclination when a running device is inclined. When the device runs on stairs, front and rear wheels 3, 4 for running on a flat surface are pulled in by driving lift mechanisms 13, 14, and a crawler running mechanism 2 is brought into contact with the ground to judge whether the device is within a proper scope for safety or not based on the comparison between the calculated value and actual value of the height of gravity in a condition in which the device is inclined.

摘要： PROBLEM TO BE SOLVED: To prevent high temperature steam and a high temperature and high pressure gas from leaking out of an interface of a rotation part by manufacturing an electric wire provided with a rotation fin while sealing the interface between mutually rotating a rotation die having a fin forming groove and a head of an extruding apparatus by pouring a lubrication material to the interface. SOLUTION: In manufacturing electric wires provided with a rotation fin, a lubrication material pouring route 91 is formed in a plug 9 for coming out prevention and the outlet of the route 91 is set to be a tip end face for screwing the plug itself and opened toward the interface between a head 2 of an extruding apparatus and a rotation die 3 having a fin forming groove where both of the head 2 and the die 3 are relatively rotated. A lubrication material 23 is poured into the interface between the head 2 of an extruding apparatus and the rotation die 3 having a fin forming groove where both of the head 2 and the die 3 are relatively rotated by continuously pouring the lubrication material 23 into the route 91 and the interface of the relatively rotating parts where a gap is easily formed is constantly sealed. Consequently, in the case a cross-linking work is carried out, high pressure steam in a crosslinking cylinder 8 can be prevented from leaking out of the interface through a communication cylinder 5.
