IPC: B66B9/04
Filed: 1978-07-07
Abstract: PURPOSE: To provide a safety system for hydraulic elevator, in which arrangement is such that alarm is produced and operation of elevator is stopped when axial displacement of oil conveying pipes is detected, so as to inspect the system before leakage of oil from the oil conveying pipes is caused, whereby it is enabled to improve safety of elevator operation.  
     CONSTITUTION: Contactors 13a, 13b are fixed respectively to oil conveying pipes 6a, 6b and switch supports 14aW14c are fixed on the floor of building by means of anchor bolts 15. Switches 16aW16c are fixed to respective switch supports 14aW14c. Here, arrangement is such that clearance between contactor 13a and switches 16a, 16b and that between contactor 13b and switches 16b, 16c are normally G4. In such an arrangement, if oil conveying pipe 6a or 6b is displaced axially through a distance G4 by reason of change of oil pressure or other, either of switches 16aW16c is set into operation and turned ON. By producing an alarm or stopping operation of elevator when either of the switches 16aW16c is turned ON, it is enabled to improve safety of elevator operation.

Title: Production of ester of acrylic acid or methacrylic acid
Inventor: FUJII MASAHIKO
IPC: C07C67/58
Filed: 1985-04-19
Abstract: PURPOSE:To recover (meth) acrylic acid after reaction of an alcohol with an excess amount of (meth) acrylic acid, by neutralizing the remaining (meth) acrylic acid and a catalyst by addition of an alkali aqueous solution, adjusting the pH and then extracting with ether. CONSTITUTION:A 4-22C alcohol is reacted with an excess amount (meth) acrylic acid in the presence of both an esterification catalyst (example; sulfuric acid and p-toluenesulfonic acid) and a polymerization inhibitor (example; hydroquinone) at 60-150 deg.C. After the water of condensation stops splitting off from the reaction system, an alkali aqueous solution is added to neutralize the remaining (meth) acrylic acid and catalyst, and then an inorganic acid (example; hydrochloric acid) is added to a separately formed water layer to make the pH less than 4, thereafter the (meth) acrylic acid in the water is extracted with an aliphatic ether (example; diethyl ether) or petroleum ether to recover. The organic layer formed after the neutralization is dehydrated under reduced pressure and filtered to obtain the aimed material. EFFECT:The excess amount of (meth) acrylic acid can mostly be recovered.

Title: Method and device for searching movement route
Inventor: NAKAHARA NAOJI
IPC: G01C21/00
Filed: 1989-03-31
Abstract: PURPOSE:To most suitably search movement routes with a small processing volume by selecting the movement route first joined to a movement route from another point and this movement route from another point to determine a movement route. CONSTITUTION:Respective movement routes connected to a first point are accumulated and are displays as a straight line having a length related to the movement progress, and respective movements routes connected to a second point are accumulated and are displays as a straight line related to the movement progress. Therefore, respective movement routes are traced while successively expanding the circle having each point as the center, and a route is determined at the time of overlap of these circles. The area in each circle is the search range in this case, but the search range is reduced to a half of that for search from one side in the simplest example because circles are expanded from both sides. Thus, respective movement routes are most suitably searched with a small processing volumes.

Title: Electronic balance
Inventor: KAWAMOTO AKIRA
IPC: G01G7/04
Filed: 1989-03-31
Abstract: PURPOSE:To improve the response by supplying a prescribed electric quantity from outside to the integration circuit of a PID controller which controls the current of a second load evaluation part every time a 1st load evaluation part has stepwise variation by one count. CONSTITUTION:When a load varies, it is considered that the electromagnetic force F1 generated by a force coil 2 increases or decreases by one step at time point t1 and t2. The servo system of the load evaluation part B operates to decrease the electromagnetic force F2 by a force coil 3 at the time t1 by the increment of the F1, but a switch 21 is closed at this time to input the prescribed electric quantity which actuates the decrease in the force F2 to the integration circuit 6a in the PID controller 6. At the time t2, a switch 23 is closed to input the prescribed electric quantity which actuates the increase in the force F2 to the circuit 6a. Consequently, the force F2 generated by the coil 3 decreases or increases stepwise at the time points t1 and t2. Therefore, measured value represented as a force F1+F2 has a little variation at the time points t1 and t2 and returns to a stable state speedily.
