Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a cutting device which can cut a material piece in accurate length and width, and allows the material piece to be used easily, for example in preparation for a case where a mark is attached to another item of product from this material piece. SOLUTION: A device to cut a long and thin material piece having flexibility into the specified length and width has a drum 2 which holds the material piece on the outside surface by means of vacuum.

Title: Buffer amplifier
Inventor: ITO YASUHIRO
IPC: H03F1/48
Filed: 1988-01-30
Abstract: PURPOSE:To improve the high speed performance and the broad band performance by comparing an input signal of a field effect transistor(TR) receiving an input signal at one of two gates and an output of a source follower means to obtain an error signal and applying said signal to the other gate of the two gates. CONSTITUTION:An input terminal 6 is connected to one gate of a dual gate field effect TR 20 being a component of a source follower and an output terminal 7 giving an output signal is connected to the source directly or via an amplifier. Then the drain current of the dual gate field effect TR 20 being the component of the source follower is set by a constant current source to maximize the mutual conductance, a potential difference between the input terminal 6 and the output terminal 7 is detected by an error amplifier 25 and it is fed to the other gate to make the potential difference between the input terminal 6 and the output terminal 7 zero. Thus, it is possible to set optionally the drain current to obtain the maximum mutual conductance by the constant current source. Thus, the high speed performance and the broad band performance are improved.

Title: Phase-locked loop
Inventor: ISOI NORITSUGU
IPC: H03L7/093
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To reduce the EMI noise of a specific frequency by providing an output frequency shifting means so as to fluctuate an output frequency and distribute a frequency generated by an EMI noise. SOLUTION: A VCO gain control circuit is added to switch the gain characteristic of VCO by the output of a gain control circuit to output a switch control signal from the gain control circuit every fixed time by a timer. At the time of switching characteristic when VCO is oscillated by some frequency, a PLL output clock frequency is varied to generate the phase shifting of its frequency dividing signal and the frequency dividing signal of an input clock signal to try to return the frequency of an output clock signal fout to a frequency before switching. Each time of switching the characteristic of the gain control circuit, a PLL output clock signal frequency fout repeats fluctuation by the width of Δf to fluctuate an output frequency to distribute EMI noise to reduce the EMI noise of the specific frequency.

Title: Control system of power supply overcurrent
Inventor: MATSUMOTO HITOSHI
IPC: H02M3/28
Filed: 1981-02-16
Abstract: PURPOSE:To perform the stable monitor for overcurrent, by cutting off the power supply to a switching control element at the primary side of a power supply transformer in case the load becomes extraordinarily heavy. CONSTITUTION:An input power supply is converted from a primary side transformer part to a secondary side transformer part of a power supply transformer part T, and a DC output is supplied to the load side. Then a stable DC output is supplied to the load fluctuation of the DC output after changing the amplitude through a pulse duration controlling element 7. In case the load becomes extraordinarily heavy, the input current flows in an abnormal way. Then a transistor TR1 works when a thyristor D1 reaches its working point. As a result, the level of the voltate Vcc of the element 7 becomes equal to the earth level to cut off the power supply to the element 7. Accordingly, the power consumption is reduced to ensure the stable monitor for the overcurrent.

Title: Bulb sealing method
Inventor: SHIBAGAKI TORU
IPC: H01J9/26
Filed: 1991-02-14
Abstract: PURPOSE:To seal a bulb certainly, with which inclination is lesser when the mount is supported by a mount holder. CONSTITUTION:An exhaust pipe 7 and a lead 8 arranged around it are inserted in a mount holder 9 of cylindrical form, and a mount 4 is held by this mount holder, wherein the lead is wound on the periphery of the exhaust pipe and inserted in the mount holder. Because the lead is wound fast on the exhaust pipe, the gap between the exhaust pipe inserted in a bulb holder and the inside of the bulb holder becomes small and uniform over the whole circumference. This lessens rattles of the exhaust pipe in the bulb holder and lessens inclination of the mount.

IPC: G02B7/00
Filed: 1985-02-06
Abstract: PURPOSE:To prevent an out-of-focus state by drilling a hole at a part where a holding plate spring of a holder for a collimator lens or a condenser lens is brought into contact with a lens holder, and applying an adhesive only at the hole area. CONSTITUTION:A hole 33 is provided at a part where a holding plate spring 31 is brought into contact with a lens holder 32. then an adhesive 34 is applied to the hole 33 to fix both the spring 31 and the holder 32 together. If the temperature rises or drops under such conditions, a point F has no shift since it is fixed by the adhesive 34. However, a slip occurs at a point G by an amount equal to a differential of heat expansion since both the spring 31 and the holder 32 are not fixed. Both points F and G are reset to their original states when the temperature is set again at its original level.
