Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To reduce the cost and space of a self-excited var compensator by eliminating the need of a phase-to-phase reactor by connecting the high-voltage sides of multiple transformers for square-wave inverters in series with the high- voltage sides of multiple transformers for PWM inverters. SOLUTION: The high-voltage sides Pa and Pb of transformers Ta and Tb for square-wave inverters are connected in series and square-wave inverters 1a and 1b are respectively connected to the low-voltage sides Qa and Qb of the transformers Ta and Tb. In addition, the high-voltage side Pc of a transformer Tc for a PWM inverter is connected in series to the high-voltage sides Pa and Pb of the transformers Ta and Tb and a PWM inverter 2 is connected to the low-voltage side Qc of the transformer Tc. The voltages outputted from the inverters 1a, 1b, 2 are outputted to a power source Vs side respectively through the transformers Ta, Tb, and Tc.  Therefore, the cross current which is generated by the unbalance between the output voltages of the transformers Ta and Tb is not generated and no phase-to-phase reactor is required, because no circulating current is generated between the transformers Ta and Tb.

Title: Logic circuit
Inventor: SHIMIZU SHOICHI
IPC: H03K5/151
Filed: 1987-08-26
Abstract: PURPOSE:To operate the titled circuit at the maximum operating frequency by connecting an inverter comprising depletion/enhancement type Schottky FETs at the post-stage of a noninverted buffer. CONSTITUTION:With an input at a high level, because a Schottky FET is employed for a FET Q2, the high level is clamped by the forward voltage of the diode. Since the gate voltage of the FET Q2 of the push-pull stage is also clamped in this way, the FET Q3 cannot turn on the FET Q6 of the next stage. The source potential of the FET Q3 cannot be at a high level because the input potential C is clamped, then the FET Q6 cannot be turned on and the drain voltage B of the FET Q6 cannot be decreased to the low level.

Title: Heat roller type fixing device
Inventor: TAKIZAWA TATSUJI
IPC: G03G15/20
Filed: 1995-07-29
Abstract: PROBLEM TO BE SOLVED: To adjust a pressing roller and a pressure roller so that a recording material may be prevented from being wrinkled and to prevent the deflection of the pressure roller by providing the pressing roller so that its axial line may be crossed with the axial line of the pressure roller and their crossed axes angle can be adjusted. SOLUTION: The pressing roller 3 for pressing the pressure roller 2 to a heat roller is provided at the rear of the roller 2, and provided so that its axial line may be crossed with the axial line of the roller 2 and their crossed axes angle can be adjusted. The roller 2 is press-contacted to the heat roller with its elasticity in a state where it is slightly squeezed. However, in the case the roller is optimally set, the pressure on both-end sides is somewhat high and the pressure in the central part is somewhat low in the pressure distribution of the roller 2, and paper feeding speed on both-end sides is a little higher than that in the central part of the roller, so that the recording material passing between the rollers is carried in a state where it is stretched right and left, thereby preventing the wrinkles from occurring in such a case.  Furthermore, the roller 2 is always pressed by the roller 3 and the deflection of the roller 2 itself is prevented.

Title: Exposure method and exposure device
Inventor: SHIBUYA MASATO
IPC: G03F7/20
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To allow pattern formation with unanimous line width accuracy between two exposure regions having the different number of exposure times by changing light intensity distribution and by exposing a plurality of times so as to permit an average effective intensity in one time exposure region and a plurality of times of exposure region on a non-linear photosensitive material to the incident light intensity to be almost matched with. SOLUTION: On a mask substrate 1, a light shield part 2 and a light- transmitting part are alternately formed, a phase shifter 3 is formed between two light shield parts and 2 photon absorption resist with the characteristic that exposure proceeds nonlinarly to the intensity of the incident light is used as a resist. Further, the transmittancy of the transmitting part of a mask pattern to be used for exposure of a two times exposure region is formed smaller than the transmittancy of the transmitting part of a mask pattern to be used for exposure of one time exposure region so as to permit the average effective strength on the one time exposure region with the average effective intensity on the two times exposure region to be matched with. As a result, in the one time exposure region and the two times exposure region, the line width accuracy of the patterns can be matched with.
