Filed: 1983-07-18
Abstract: PURPOSE:To obtain continuously a rod material which has a relatively large sectional area and of which the sectional shape is not flat with a process for running continuously a molten metal downward toward the inside circumference at the hem of a rotary disc and manufacturing said rod by specifying the inside circumferential shape of said hem and the taking-out of the solidified wire rod. CONSTITUTION:A circumferential groove 2 having the base of a semicircular section cut in the direction where both accelerations or gravity and centrifugal force are combined is provided to the inside circumference of the hem of a hemmed disc 1 which rotates quickly. A molten metal 4 is conducted toward the inside of said groove by continuous downflow from a nozzle 3. The metal 4 is quickly cooled and solidified to a wire rod 5 by the extraction of the heat resulted from the contact with the inside of the groove 2. The wire rod is taken out of the groove 2 by a scraper 6 during the time since the metal 4 contacts with the groove 2 until the metal makes one turn together with the disc 1. The removed wire rod is led out by a guide tube 7.

Abstract: PURPOSE: To improve production efficiency by bringing glass lump in a high-temp. softened state into contact with the attraction surface of an attraction part to deform the glass lump and to form the glass lump to the specified shape corresponding to the shape of the attraction surface and attracting the glass lump by specific attraction force to the attraction part and transporting the glass lump to molds. CONSTITUTION: A prescribed amt. of the fused glass lump emitted from a melting furnace is received on a die 1 and a die shaft 36 is lowered and is put into a substitution chamber. An inert gas is introduced into the chamber when the surface viscosity of the fused glass lump attains 10<5> to 10<8> dPa.s. Attraction fingers 34 are then moved over the fused glass lump and the shaft 36 is risen to bring the surface 24a on the fused glass lump on the die 1 into contact with the annular attraction surface 34a of the attraction finger 34, then the fused glass lump is pressurized. The surface 24a on the glass lump is pressurized and deformed until the pressure attains about 5N, by which the fused glass lump is brought into tight contact with the entire periphery of the attraction surface 34a.  The fused glass lump is attracted and held by maintaining the pressure within the attraction port at a pressure difference lower by 1×10<2> to 5×104Pa than the external pressure. The fused glass lump is thereafter transported to the molds and is press formed, by which an optical element is obtd.

Title: Trouble detection reporting system for microprocessor
Inventor: NAKAGAWA TATSUHIKO
IPC: G06F11/30
Filed: 1989-05-23
Abstract: PURPOSE:To improve the reliability and the maintainability without damaging conventional functions by recognizing the restart due to a microprocessor reset pulse by a microprocessor itself to output an alarm at the time of detecting abnormality. CONSTITUTION:A microprocessor 1 has software to periodically output a timer reset pulse 11 in the steady operation state; and if the microprocessor 1 falls into the abnormal state by some external abnormality and the output of the timer reset pulse 11 is stopped, a microprocessor reset pulse 12 is outputted from a watchdog timer circuit 2 after a certain time. When the restarted microprocessor judges that it is restarted by the microprocessor reset pulse 12 due to abnormality detection, the microprocessor enters into the steady operation after outputting a microprocessor reset alarm 15 by its own software. Thus, combinational trouble of external states is recognized.

Abstract: PURPOSE: To enable the grating plates of a sufficiently large inter-grating spacing to be utilized and perform scanning position detection of high accuracy by the constitution comprising splitting a scanning beam for measurement to a plurality, deviating the mutual grating positions of the grating plates being scanned by each scanning light and combining the detection signals by the respective grating plates later.  
     CONSTITUTION: A beam splitter 11 is provided to the optical path of scanning light 4 scanning the plane to be scanned 5 and is so arranged that reflection takes place on both front and back surfaces thereto to provide two branched beams 81, 82. Photo detectors α, β are disposed behind the grating plates A, B which are scanned by two pieces of these scanning beams 81, 82 for measurement. Here, the inter-grating spacing D of the respective grating plates A, B is taken sufficiently larger than the spot diameters of the scanning beams 81, 82 and the gratings of the grating plates A and B are deviated with each other by 1/2 the inter-grating spacing D. Such constitution eventually results in the same thing that measurement is done by the grating plates having the inter-grating spacing of D/2, thus the measurement accuracy becomes twice higher.

Abstract: PROBLEM TO BE SOLVED: To provide a hydrostatic main spindle control device for a processing machine; such as a grinding machine, to effectively utilize energy of a rotary main spindle and control a position by a small force and besides to improve machining precision. SOLUTION: This hydrostatic main spindle control device incorporates one or more control systems selected from a non-inference control system, a main axial dynamics control system, and a gyro compensation control system, as under-defined. The non- interference control system is a control system that through pressure control of a hydrostatic part using a servo valve, the translational force and torque of a main spindle at a coordinate system being a target are generated. A main spindle control system is a control system that a control system is switched matching with the rotation time or the stop time of the main spindle. The gyro compensation control system is a control system that by considering the gyro effect of a main spindle during rotation of the main spindle, gyro moment of the main spindle is positively utilized in the drive direction of the main spindle.  A preferable mode is that position detecting sensors (30-1) 30-2 to detect the deviation in a radial direction of the hydrostatic main spindle and position detection sensors 30-31 are arranged at a hydrostatic main spindle control device and control is effected by obtained position information.

Abstract: PROBLEM TO BE SOLVED: To restrain the output degradation due to contact resistance in a metal contact of a battery or the like over a long period at a low cost by arranging a conductive contact point having corrosion resistance at least at a part of a conductive gas passage plate abutting on a gas diffusion electrode. SOLUTION: A conductive contact point is not a continuous film but preferably formed into a discontinuous island-like shape, and thereby, a material constituting a protective film can be saved and a film forming time can be reduced. Specifically, a low-conductivity film such as an oxide film formed on the surface of a metallic conductive gas passage plate during a normal storage condition is previously removed in order to secure the conductivity of the protective film and enhance the durability thereof and thereafter, the protective film is formed. At that time, the island-like protective film is formed by adjusting the film forming time and by optimizing the temperature of the gas passage plate.  Additionally, it is recommended that the formation of another protective of an organic substance and an oxidation treatment are carried out to the surface of the conductive gas passage plate not covered with the protective film.
