Title: Production of sputtering target material
Inventor: YANAGIMOTO MASARU
IPC: C23C14/34
Filed: 1988-07-13
Abstract: PURPOSE:To sinter powder of an alloy of components required for a sputtering target to a nonporous state with 100% density in a short time by sealing the powder in a malleable metal vessel and carrying out compression at a proper temp. CONSTITUTION:Powder of an alloy for a sputtering target having <=1mum particle size is sealed in a malleable metal vessel, heated to a temp. below the m.p. of the alloy and compressed under >=2,000kg/cm<2> pressure. Even in the case where the alloy powder is hard particles of an intermetallic compd., the powder is sintered to a nonporous state with 100% density in a short time because of the high pressure. Since the high pressure shortens the time required to sinter the powder, grain growth is suppressed and the grain size of the product can be limited to the particle size of the powder as starting material.

Title: Stacked newspapers transport method
Inventor: AOKI MINORU
IPC: B65H33/00
Filed: 1981-11-02
Abstract: PURPOSE:To prevent breakup of shelves of newspapers by providing a plurality of flat belts having coefficient of friction smaller than the coefficient of friction between newspapers and elevating receiving plates having smaller coefficient of friction which are disposed between the flat belts, thereby to control the  speed of transporting shelves of newspapers. CONSTITUTION:If there is no interval between stacks P, a standby signal is sent out from an address sheet transfer loader. When the leading end of the stack P is transported onto the front photoelectric tube 35, an air cylinder 18 is worked by detection of the photoelectric tube 35 so that a receiving plate 15 rises to project over a flat belt 6 and stop translation of the stack P. As the upper surface of the receiving plate 15 has the coefficient of friction smaller than the coefficient of friction between newspapers, the stack is not stopped suddenly so as to prevent collapse of cargo stack. In case of retranslation, the cylinder 18 is contracted to lower the receiving plate 15 and transfer the stack P onto the flat belt 6 surface. At this time, there is no possibility of breakup of loads due to sudden acceleration, because the coefficient of friction of the flat belt 6 is also smaller than the coefficient of friction between the newspapers.

Title: Common mode choke coil
Inventor: KURIYAMA MEIKAI
IPC: H01F37/00
Filed: 1983-09-23
Abstract: PURPOSE:To obtain high noise rejection characteristic and realize automatic winding process by winding a lead to the groove of the bar type magnetic material provided with a spiral groove and covering the external circumference of said winding with a magnetic plate. CONSTITUTION:After winding a lead 1 along the spiral groove 4a of a bar type core 4, a magnetic tape 5 is wound around it. With such structure, the winding process can be done automatically with a winding machine, in view of mass- production. In addition, since the magnetic path is formed as the closed loop, an inductance increases. Moreover since the lead 1 is wound along the inside of groove 4a, an electrostatic capacitance to the adjacent coil is reduced and a filter characteristic can be improved up to the high frequency band.

Title: Amplifying circuit
Inventor: NORO MASAO
IPC: H03F1/02
Filed: 1991-06-20
Abstract: PURPOSE:To improve the tracking performance with respect to a steep rise of a large amplitude input and to attain a high efficiency in an amplifying circuit for an audio power amplifier or the like. CONSTITUTION:A main power supply path 42 through which a major power is supplied and an auxiliary power supply path 48 through which an auxiliary power is supplied are provided as a power supply source path for an output stage transistor(TR) Qa. The efficiency of the main power supply path 42 is improved by switching drive with a switching TR Qs. The response of the main power supply path 42 is not excellent since a smoothing coil L1 is inserted into the path 42. Thus, deficient power is supplied from the auxiliary power supply path 48 with an excellent response to the TR Qa against a steep input rise. Even when a large amplitude input rises steeply, since the auxiliary power supply path 48 is driven by a large voltage +B similarly to the case with the main power supply path 42, required power is supplied to the path 48 even against the steep rise of the large amplitude input.

Title: Spectacle frame parts
Inventor: TAKEDA TOMIHIRO
IPC: B29D12/02
Filed: 1987-07-15
Abstract: PURPOSE:To form a tough lens holding frame and to reduce the weight thereof to the same extent as the weight of the conventional spectacle frame made of a synthetic resin or to the lower weight by constituting the holding frame of a polyether ether ketone or short fiber reinforced polyether ether ketone. CONSTITUTION:The lens holding frame 2 as spectacle frame parts consists of the polyether ether ketone or the short fiber reinforced polyether ether ketone. A pair of upper and lower endpieces 3a, 3b are formed integrally with the holding frame 2 to the open end of the holding frame 2. The polyether ether ketone and short fiber reinforced polyether ether ketone used for these parts have high heat resistance and the insertion of a lens to the holding frame 2 by heating and softening the holding frame 2 is difficult and, therefore, the holding frame 2 is preferably made into an open ring construction. The possibility of flawing of the holding frame by the corner part of the lens and the breakage from the weakest part of the holding frame is thereby eliminated.
