Abstract: It is an object of the present invention to provide a novel production method which makes it possible to obtain a molded product containing a P3HB-based resin through an injection blow molding method and a technique for using such a method. The object is achieved by providing a method for producing a molded product containing a P3HB-based resin, the method including the steps of: (A) plasticizing a resin composition containing a P3HB-based resin; (B) subjecting the plasticized resin composition obtained in the step (A) to injection molding to obtain a preform; and (C) subjecting the preform obtained in the step (B) to blow molding to obtain a molded product.

Abstract: When the memory board is not mounted onto the contact terminal group in the body section, the upper portion of the connecting section in the contact terminals located in a midportion of the contact terminal group abut, respectively, to the upper periphery of the gap-adjustment wall section at a predetermined pressure, and the upper portions of the connecting sections of the contact terminals located at the opposite ends of the contact terminal group abut, respectively, to the outer periphery of the adjustment end sections of the hook members.

Abstract: A one-way rotary damper comprising a housing, a rotor consisting of a braking disk accommodated in a cavity of the housing and a shaft unitary with the braking disk and projecting toward the outside of the housing, viscous oil filling the housing cavity for applying shearing resistance against rotation of the rotor, a driven gear rotatably mounted upon the end of the rotor shaft projecting outside the housing so as to be free to rotate with respect thereto and formed on its surface facing the housing with a concentric depression consisting of a shallow circular depression and a deep outer annular groove surrounding the circular depression, a coupling disk which is identical in diameter with the circular depression and is fixed on the end of the rotor shaft projecting outside the housing so as to be disposed upon the circular depression, and a clutch spring disposed so as to extend along a radially outer surface of the coupling disk and a radially inner surface of the outer annular groove for enabling the driv

Abstract: In an apparatus such as a transformer comprising at least a magnetic core and a main winding, a method and apparatus for biasing of a magnetic material is characterized in that an auxiliary winding N2 is added to said magnetic core 2 and a predetermined amount of demagnetizing current, which will reduce the magnetic flux caused by said main winding N1 by a predetermined amount, is caused to flow through said auxiliary winding N2 in synchronism with an increase in the magnetic flux caused by said main winding N1 to prevent the magnetic saturation of the magnetic core during the time that the magnetic flux caused by the main winding is increasing.

Abstract: A self-excited switching type D.C. power supply for producing a stabilized output signal. The power supply is provided with a rectifier, a primary winding of a transformer, a switching transistor and a resistor connected in series with one another between first and second input terminals of the power supply. The transformer is further provided with a secondary winding, a Zener diode, a capacitor and a resistor connected in series with a photocoupler. The photocoupler is connected in series with a pair of control transistors which control the operation of the switching transistor. The switching frequency of the switching transistor is stabilized by providing a quiescent time period during which the switching transistor is disabled.
