Title: Movable table device
Inventor: HORI KOHEI
IPC: B23Q1/26
Filed: 1984-12-27
Abstract: PURPOSE:To prevent damage to a bearing and improve precision in a movable table, which uses static pressure type pneumatic bearing, by providing a strain gauge in a connection part between a driving mechanism and a table main body and giving an alarm when the strain exceeds a predetermined value. CONSTITUTION:High-pressure air from an air supply system 9 is taken in a slit 8 between a shaft 6 and a bearing seat 4 and supports the shaft 6 and the bearing seat 4 in a noncontact condition. Under this condition, in case a movable table 3 is moved and the shaft 6 is brought in solid contact with the bearing seat 4 due to some reason, stick-slip movement is produced and the movable table 3 repeats movement and stoppage periodically to cause a connecting lever 19 to produce a strain, which is detected by a strain gauge 21 and the output is inputted to an information circuit 22. Comparison 23 of this input with a set value is made, and when it exceeds the set value, a motor 17 is stopped through a control circuit 25. By this structure, lethal damage to the bearing can be prevented and improvement of precision can be made.

Title: Insulating ring for cylindrical battery
Inventor: SATO HIROFUMI
IPC: H01M6/08
Filed: 1993-11-04
Abstract: PURPOSE:To sufficiently eliminate warps and curves of an insulating ring for cylindrical batteries wherein the ring is prepared from a raw sheet prepared by rolling resin into a thin sheet and rolling the sheet. CONSTITUTION:A plurality of stripe grooves 3 are formed in both front and back sides of a circularly formed main body 5 with prescribed width W1 and thickness T1 in the direction rectangular to the rolling direction of resin. The pitch L1 of these grooves 3 is set to be a half of the width W1 of the main body 5 or less and the depth of each groove 3 is set to be 2-15% of the thickness T1 of the main body 5. Consequently, due to a plurality of the stripe grooves 3 formed in the main body 5, the stiffness of the insulating ring 1 is lowered, and the grooves 3 are surely formed in the main body 5 by setting the pitch L1 of these grooves 3 to be a half of the width W1 or less. As a result, the curling property due to its being rolled condition scarecely remains and no warp is observed in the insulating ring. Since warp and curve are prevented only by adding the process to form stripe grooves in the raw sheet, the productivity is not lowered greatly.

Title: Thermistor failure detecting method
Inventor: KODAMA HIROAKI
IPC: G01K7/24
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To detect changes in the resistance-temperature characteristics of a thermistor as a failure correctly by measuring and comparing a water temperature in a tank and a room temperature in the vicinity of the tank after predetermined standby time set in advance from the halt of electric power supply for a heater. SOLUTION: For maintaining warm water regularly used as cleaning water at a predetermined temperature, electric power supply for a heater is turned on and off so that the water temperature T of the warm water 2 remains within a predetermined range on the basis of the measurement output of a thermistor 4. At the time of detecting a failure in the thermistor 4, power supply for the heater 3 is halted. After a period of standby time set in advance i.e., the period of time till the water temperature T of the warm water 2 becomes equal to a room temperature TA in the vicinity of a water tank 1, the water temperature T is measured by the thermistor 4, and the room temperature TA is measured by a room temperature sensor 5.  Here, in the case that the resistance-temperature characteristics of the thermistor 4 are normal, the water temperature T is lowered to and becomes approximately equal to the room temperature TA. In the case that they are changed, errors occur in the water temperature T and the room temperature TA. Therefore, it is possible to determine the presence or absence of a failure correctly depending on whether these errors lay within a predetermined allowable range with reference to the room temperature TA.

Abstract: PURPOSE:To attain a long period test without requiring operator's operation by checking read data obtained at the time of succeeding in retrial by recovery processing at the time of succeeding in reverse direction reading/retrial, and when the read data are normal, executing normal end and starting the succeeding processing. CONSTITUTION:When reverse direction reading/retrial success is generated, a magnetic head position is moved to a position to be set up when a normal reading command is processed. Then, read data obtained at the time of succeeding in retrial are checked. When a processing command is BACK READ, data are checked by regarding the data as the ones read out by a FORWARD READ. When a processing command is a FORWARD READ, data are checked by regarding the data as the ones read out by a BACK READ. When the read data are normal, the reading processing is ended without executing retrial and the succeeding command is started. When the data are abnormal, a monitor 1 is informed of a data comparison error and the processing is ended.
