Title: Propeller fan device
Inventor: TODAKA MASATAKA
IPC: F04D29/38
Filed: 1985-04-10
Abstract: PURPOSE:To make it possible to obtain the constant cooling speed which always enables the achievement of a predetermined cooling temperature level, regardless of a load in a refrigerating chamber, by forming the fan blade of a shape memory alloy whose skew changes according to the fluctuation of surrounding temperature. CONSTITUTION:A fan blade 102 is made of a shape memory alloy, which can be changed to a specific shape according to surrounding temperature, and fitted to a boss 103 of resin or metal to form a propeller fan device 103. As a showcase 5 is operated and the inside of a refrigerating chamber 16 is cooled down, the skew of the fan blade 102 gradually changes and gets smaller, compared to its shape at the start of operation, as shown by a dot-dash line. Consequently, it is possible to obtain the constant cooling speed which always enables the achievement of a predetermined cooling temperature level, regardless of a load in the refrigerating chamber 16, and fan efficiency can be improved.

Title: Swaging machine for tube stock
Inventor: SUZUKI YOSHINORI
IPC: B21K1/06
Filed: 1995-03-31
Abstract: PURPOSE: To shorten cycle time by allowing a lower product release to be raised linked with the elevation in a specific stroke of an upper product release, by means of a stopper at the upper end of plural connecting pins erected on the lower product release, and thereby enabling simultaneous working of both ends. CONSTITUTION: After the upper end side of a tube stock 20 is first released from the upper die 10, which is then further raised, the upper product release 13 is also integrally raised, thereby abutting the flange 7a of each connecting pin 7 on the upper face of the product release 13. With this state maintained, when the upper die 10 is further raised, the lower product release 6 is integrally raised through the connecting pin 7-7, making the release cylinder 6a move upward between a lower core bar 4 and a lower die 5, thereby releasing the lower end side of the tube stock 20 from a lower die 3 side. Thus, when the lower side is released, the upper die 10 is at the end of elevation, completing one process of a swaging machine 1. Consequently, the process is simplified in the swaging of this kind of tube stock 20.

Title: Current amplifying circuit
Inventor: HAYASHI TOSHIO
IPC: H03F3/34
Filed: 1981-05-22
Abstract: PURPOSE: To obtain a current amplifying circuit in which the current amplifying factor can be set with high accuracy and the power consumption in the standby state is zero, by constituting the titled circuit of a current mirror circuit,  potential difference detecting circuit and two transistors (TRs) and resistors.  
     CONSTITUTION: An input current I in  generates two currents equal to the I in  at a current mirror circuit 2; one is given to a terminal 10 of a potential difference detecting circuit 3 and another is applied to a base 14 of a TRQ 4  and a current output terminal 11. If a potential at a voltage input terminal 13 is assumed to lower than a potential at a voltage input terminal 12, a current of I 3 -I 2  flows from the base of the TRQ 4  since, I 1 <I 3 . This current is amplified at TRs Q 4  and Q 5  and a current I out  flows to a resistor RE 6  to boost the potential at the terminal 13. Inversely, if the potential at the terminal 13 is higher than the potential at the terminal 12, the phenomenon is reversed, resulting in the drop of potential at the terminal 13. Thus, the current amplification factor can be set with high accuracy, and the power consumption at non-operation, that is, the standby power can be reduced to zero for the titled current amplifying circuit.

Abstract: PURPOSE:To perform high-precision measurement regardless of a contact state by providing a circuit to correct a time stagger error of an ON-OFF signal changed due to a contact state between a touch probe and a substance to be measured and the intrinsic characteristics of the touch probe. CONSTITUTION:A calibration circuit 9 to form a relation formula between a time stagger error and a contact angle, and intrinsic characteristics and rigidity of a measuring system is formed in an NC device 4.
