Inventor: TAKESHITA TETSUO
IPC: C25B3/25
Filed: 1983-02-09
Abstract: PURPOSE:To produce an aq. acrylic acid soln. having high purity by delineating an electrolytic cell into an anode chamber, cathode chamber and intermediate chamber by means of cation exchange membranes, supplying an aq. acrylate soln. expressed by the formula into the intermedite chamber and performing electrolysis. CONSTITUTION:An electrolytic cell 1 is delineated to an anode chamber 3, an intermediate chamber 4 and a cathode chamber 5 by means of cation exchange membranes 2, and electrodes 6, 7 are mounted in the chambers 3, 4. An aq. soln. 11 of the acrylate (X: Na, K, Li, NH4, Ca, Mg, Al; n: 1-3) expressed by the formula is circulated in the chamber 4. A dilute sulfuric acid soln. 12 and an aq. caustic soda soln. 16 are respectively circulated in the chamber 3 and the chamber 5. When a DC voltage is impressed between the electrodes 6 and 7, hydrogen ion migrates from the chamber 3 to the chamber 4 and converts the acrylate 11 to an acrylic acid. For example, sodium ion, etc. migrates from the chamber 4 to the chamber 5. The acrylate 11 is thus converted to the acrylic acid without adding an acid in the chamber 4.

Title: Attachment structure for mirror
Inventor: TAKAHASHI KOJI
IPC: G02B7/198
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To stably attach a mirror without causing any deviation of reflection angle due to vibration etc. SOLUTION: In the case of regarding the mirror 16 as a reference, when an adjusting screw 24 is screwed in, a reaction force R is applied on the adjusting screw 24 along a line V vertical to the reflection surface of the mirror 16 to obtain the component of force of Rh=Rsinθ in the downward direction and the component of force of Rv=Rcosθ in the direction toward the rotational center axis L of the adjusting screw 24. Thus, an angular moment corresponding to the length of an arm from the top end 24A is generated at the parts A and B where the adjusting screw 24 is threaded into a screw hole 30. Thus, the engagement parts A and B are energized upward (direction shown by an arrow A) to come the adjusting screw 24 into close contact with the screw hole 30 without any clearance.  Thus, the adjusting screw 24 is rotated without causing any backlash to stably hold the mirror at the adjusting time.

Title: Method of controlling speed of tool feed in numerical-controlled processing machine
Inventor: SUZUKI WATARU
IPC: B23Q15/013
Filed: 1983-02-08
Abstract: PURPOSE:To make an operation unmanned and shorten processing time, by detecting a difficult processing point from the processing data of an auxiliary memory to apply an instruction to start lowering the feed velocity of a tool before the completion of a speed change action. CONSTITUTION:When the action of a numerical controller 6 is instructed through a keyboard 8, processing data for measurement points 0-3 are read from an auxiliary memory 7 to calculate the distance 12 between the measurement points 2, 3. Since the region between the points 2, 3 is flat, the distance is equal to that between X-Y coordinates, so that the controller 6 selects a high feed speed. When it comes to the region between measurement points 4, 5 after sequential selected actions, a low feed speed is chosen and a numerical-controlled processing machine is instructed in accordance with the data change time before the switchover of the tool feed speed to process the region between the points 4, 5 at the low feed speed. When the processing proceeds on the flat region to a measurement point 16, the speed switchover time does not need to be taken into consideration, so that only a high-speed instruction is applied. The machine is thus run in an unattended manner at a high rate of operation.

Title: Piping warming up control device
Inventor: FUKUSHIMA KOUICHIROU
IPC: G01D15/16
Filed: 1984-02-06
Abstract: PURPOSE:To device rapid transfer of piping to a heating region with the heat stress of the piping keeping below a specified value by setting an initial condition so that a steam possessing larger temperature difference is sent to the piping when the temperature of the inner wall of the piping is lower and taking longer time in heating the piping when the temperature difference is larger by making the valve opening smaller. CONSTITUTION:In passing steam to a main pipe 13 by opening a bypass valve 7 of a boiler outlet port stop valve, when a metal temperature TM is low the steam temperature TS at the boiler outlet port is set steeply higher, which is done because the metal absorbs a great amount of heat from the steam until it rises up to a saturated temperature and lowers the steam temperature. The initial openings O of the bypass valve 7 and a drain valve 8 in passing steam to the main steam pipe 13 are made small when the temperature difference DELTAT between the steam temperature TS right before the valve 7 is opened and the metal temperature TM because the generation of heat stress is generally large. While the temperature difference DELTAT is large the opening is kept long to wait for the approach of the metal temperature TM to the steam temperature TS. When the opeation enters to the drain valve control under normal heat stress of piping the metal can pass through the saturated steam region without producing exessive heat stress.

Title: Increasing method of heat transfar capacity for heat pipe
Inventor: FUKUI KOUICHIROU
IPC: F28D15/00
Filed: 1979-02-23
Abstract: PURPOSE: To increase the heat transfar capacity by inclining in a fixed angle against the horizontal surface by positioning the evaporation element at the low side.  
     CONSTITUTION: The evaporation element A of a heat pipe is positioned at the lower side having a inclined angle θ of 20W70° against the horizontal surface L. By this configuration, the operation liquid develops the vapor 2' from the evaporation element A to flow in an arrow direction, permitting to condense 2" at the condenser B for descending. This allows the contacting surface between the ascending vapor and the descending condensing liquid to reduce owing to providing the inclined angle θ. Consequently, the pressure drop of condensing liquid can be minimized, which allows to increase remarkably the head difference in comparing with the horizontal condition. Accordingly, this enables to increase the heat transfar capacity.

Abstract: PURPOSE:To make it possible to form an optimum clearance between the inner peripheral surface of the bore of a cylinder and a rolling piston without any special centering devices being required with no special accuracy in fabrication being required for component parts such as, for example, the piston and the cylinder, by utilizing a resin film formed on the inner peripheral surface of the cylinder bore. CONSTITUTION:The bore 3 of a cylinder 4 is formed, on the inner surface thereof, with a resin film 14 having a thickness corresponding to an initial set gap delta defined between a rolling piston 7 and the inner peripheral surface of the bore 3 of the cylinde 4 for permitting the piston 7 to rotate. Accordingly, after the piston 7 is incorporated in by being biased toward the side of the bore 3 of the cylinder 4, the piston 7 is rotated in this condition to scrape off the resin film 14 on the bore 3, and thereby, a minimum gap by which the piston 7 is smoothly rotated, is formed between the film 14 and the piston 7 over the entire area of the inner peripheral surface of the cylinder 4. With this arrangement, the above- mentioned purpose may be easily attained without any special centering devices being required with no special accuracy in fabrication being required for the component parts such as, for example, the piston 7 and the bore 3.

Title: Commutation-failure protective circuit
Inventor: ITO KATSURO
IPC: H02M7/515
Filed: 1994-02-17
Abstract: PURPOSE:To detect a commutation failure promptly and prevent later duplicated failures in a thyristor converter, by advancing an ignition phase to a given advanced phase on the basis of an output signal supplied from a commutation- failure detecting circuit when there are no marginal angles at a thyristor valve. CONSTITUTION:When a thyristor valve 13 does not open and a commutation failure takes place though a continuity-term signal (b) from a control circuit 14 becomes zero, an output signal (h) from an AND circuit 20, which receives a signal (e) and an output signal (g) from a one-shot pulse generator circuit 19, remains still zero. When an output (k) from an on-delay circuit 22 becomes 1, a commutation-failure protective signal as an output of the AND circuit 20 becomes also 1. By using the commutation-failure protective signal as a phase advancing signal in ignition phases of a thyristor converter 1, the phase is advanced much sooner than a conventional case, and therefore the duplicated commutation failures can be prevented.
