Title: Checking method of moisture absorption of fibrous material laminate molding insulating member
Inventor: MIYAZAKI SHIROU
IPC: H01F41/12
Filed: 1984-05-23
Abstract: PURPOSE:To check the separation of layers to be generated to a fibrous material laminate molding insulating member by a method wherein solid paraffin is molten to be applied on the surface of the edge part of the fibrous material laminate molding insulating member, and after then, assembled in an electric apparatus main body to be dry-treated. CONSTITUTION:Solid paraffin 4 is molten to be applied to the whole surface or at least to the surface of the edge part of a pressboard laminate molding member 3. The member 3 applied with paraffin 4 like this is assembled in a transformer main body, the whole is dry-treated, and containing water of the insulating member is reduced. Because the member 3 applied with paraffin 4 is dry- treated having small water content as it is together with the transformer main body, the separation of layers of the pressboard laminate molding member 3 is removed.

Title: Printer of sublimating type
Inventor: MITSUDA HIROSHI
IPC: B41J2/36
Filed: 1991-05-09
Abstract: PURPOSE:To keep a recording density constant by a method wherein a transmittance of an ink sheet is detected, and a thermal head is driven by a proper density signal based on an operation result of a comparison of a recording density with a standard density. CONSTITUTION:A light emitting element 8 and a light receiving element 9 are disposed across an ink sheet 3 for measuring a transmittance of the ink sheet 3. The thickness of an ink layer 4 is evaluated. Using a fact that a recording density is substantially proportional to the thickness of the ink layer 4, an operation circuit 10 evaluates a proper density signal by referring to an energy table 11, converts the signal to an energy (voltage or current) in accordance with the thickness of the ink layer 4, and supplies it to a thermal head drive circuit 12. In this manner, an energy to be applied to a thermal head 1 can be automatically controlled, whereby a recording density can be always kept constant.

IPC: H02H3/20
Filed: 1991-02-04
Abstract: PURPOSE:To protect a load by inserting an abnormal voltage detecting circuit between a neutral line and a joint of two equivalent impedances arranged in a single-phase three-wire distribution line and then driving a trip coil with an output from the abnormal voltage detecting circuit thereby interrupting the circuitry. CONSTITUTION:A phase interruption protective circuit breaker 1 is connected with a single-phase three-wire distribution line between a power supply transformer 2 and loads 3, 4. Equivalent impedances 5, 6 are connected in series between phase A and phase B voltage lines, and an abnormal voltage detecting circuit comprising a rectification bridge 7, a Zener diode 9 and a photocoupler 10 or 20 is inserted between the joint of the equivalent impedances 5, 6 and the neutral point of the line. When the capacities of the loads 3, 4 are imbalanced significantly to bring neutral lines N, N' into disconnected state, DC voltage rectified through the rectification bridge 7 exceeds the threshold of the Zener diode 9 to conduct the photocoupler 10. Consequently, an SCR 13 is conducted to drive a trip coil 12 thus opening a main contact 18 and protecting the loads 3, 4 against abnormal voltage.

Also, even when a hole 28 provided at the end of the ceramic support rotary shaft is biased, shear of its center with respect to that of the pressure transmission means for a weight sensor will not occur since the contact portion with the plate spring is formed by a metal mold of accurate outer periphery. Shear of the center of the resin contact portion i.e., pressurizing portion with respect to that of the pressure transmission means of the weight sensor will not therefore occur and so a weight property is easy to obtain.

Title: Solar heat collecting device
Inventor: KANETANI KIYOUICHI
IPC: F24J3/00
Filed: 1980-07-31
Abstract: PURPOSE: To economize the electric power consumption, prolong the service life of a pump and as well as stabilize the return temperature of circulating water by a method wherein a heat carrier circulating pump is driven by the electrical output from solar cells and the circulating flow rate of the heat carrier is determined in proportion to the insolation rate.  
     CONSTITUTION: The solar cells 6 are continuously provided at the heat collecting side in the circulating passage having a collector 1, a heat accumulator 2 and a heat pump 3 therein. The output terminals of the solar cells 6 are connected through a control switch 8 to the heat pump 3. The heat pump 3 is constituted to be driven by the electrical energy generated in the solar cells 6 in proportion to the insolation rate, resulting in determining the circulating flow rate of the heat carrier. In such a manner as mentioned above, because the heat pump 3 is driven by the output from the solar cells 6 proportional to the insolation rate, the electric power consumption is economized and no generation of hunting in pumping operation is resulted. Furthermore, because the heat carrier with constant temperature flows from the collector 1 into the heat accumulator 2, the constant return temperature of circulating water is resulted irrelevant to the change of insolation rate.
