Title: Laminated sheet without burr, and its manufacture and device
Inventor: HASEGAWA HIDEO
IPC: H02K15/02
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To manufacture a laminated sheet product at low cost without burrs at a key part, by stamping out strip sheets along the external form after stamping them out from below for the first to the Lth and from above for the L+1th to the nth, and then, integrating them. SOLUTION: A laminated rotor core 20 is constituted by stacking three sheets of rotor core elements, and the rotor core 15 positioned in the lowermost position is a rotor core element stamped with a lower die, and other rotor cores 16 and 17 are rotor core elements stamped with upper dies. Then, the upward burrs 35 produced at the topside of the element 15 stamped with a lower die and the downward burrs 36 produced at the bottom of the rotor core element 16 stamped with an upper die are press-fitted and united with each other in a state of facing, so they do not project out of a winding part. Moreover, the burrs 36 at the downside of the uppermost rotor core element 17 with an upper die are abutted against and suck fast to the shear drop at the topside of the rotor core element 16 stamped with an upper die right below it, so they do not project out of the winding part.  As a result, a laminated core without burrs at the winding can be manufactured at low cost.

Title: Temperature adjustment of stock refrigerator
Inventor: YAMAGAMI HIROZO
IPC: F25D11/00
Filed: 1988-05-11
Abstract: PURPOSE:To reduce the difference between the actual temperature and set temperature even if there was an error in the sensor installation location by installing temperature sensors across a cooling unit so as to allow the temperature control by computing the refrigerator temperature based on the detected temperatures by said sensors, while, if there is a malfunction in one of the sensors, the detected temperature by the other sensor is used as the refrigerator temperature. CONSTITUTION:When first and second temperature sensors 9, 10 are operating normally, the temperature of the refrigerator interior space 11 is computed from those which are detected by them, and the control output will be ON if the refrigerator temperature is higher than the upper limit of the set temperature, OFF if that is lower than the lower limit and will be continued if the refrigerator temperature is inbetween. If the sensor 9 is found to be faulty and the sensor 10 is working normally, the temperature detected by the sensor 10 is used as the refrigerator temperature, and afore-said control is performed. If both of them are faulty, the control output will be ON unconditionally. Therefore if either one of the sensors becomes faulty, the control will be such that the control point is displaced by DELTAt/2 in relation to the set refrigerator temperature. Further, even if the sensor locations are inadvertently reversed, the control will be not much out of the set temperature, increasing the versatility of the on-site sensor installation.
