Title: Method of detecting reference phase of regenerative inverter
Inventor: KIKUCHI YUJI
IPC: H02M7/757
Filed: 1990-11-27
Abstract: PURPOSE:To prevent the malfunction by the power source distortion of a phase detector by simple system constitution and operation method by providing a means, which detects the reference phase, with a timer, which follows the cycle of the power source, and controlling the phase of a regenerative inverter by the estimated power source cycle that the timer holds. CONSTITUTION:The reference phase that the reference phase detection circuit 7 detects is a power source phase zero cross signal, and the edge of zero cross exists three times between 0 and 2pi. Out of them, the two times in last transition are checked, and the section between them is made to correspond to sin table 11, and is made AC power source voltage detection signal. It is made to output the estimated reference phase by a timer besides the phase zero cross detection signal as the AC power source voltage detection signal. That is, though the power source reference phase is usually detected from the output voltage of a regenerative inverter 2, when instantaneous power stoppage or open phase occurs or in case that it loses the basic power source phase, the estimated reference phase by the timer is adopted.

Title: Formation of fine pattern
Inventor: KAWAI AKIRA
IPC: H01L21/3213
Filed: 1989-12-14
Abstract: PURPOSE:To compensate a shift in a focus position in an upper part and a lower part of a stage to obtain a well-finished resist pattern by applying a transparent film having a refractive index higher than that of resist on the resist to flatten the stage and exposing it. CONSTITUTION:At the time of patterning in an upper part and a lower part of a stage of a substrate 1 having a high difference of level (1 to 2mum), photoresist 4 of a refractive index n1 is applied. A transparent film 6 having a refractive index n2 larger than the refractive index n1 is applied on the resist 4. At this time the transparent film 6 is applied so that its thickness is as thin as possible in the upper part of the stage and thick in the lower part of the stage to be flattened. Then when a focus is aligned in the upper part of the stage the time of exposing for pattern transfer, light refracted by air and an interface of the transparent film will reach there. A focus position shifts toward the substrate to eliminate defocusing in the lower part of the stage at this time. Thus defocusing in the lower part of the stage is eliminated by the transparent film 6 so that a pattern aligned in size in both the upper part and the lower part of the stage can be obtained.

Title: Memory circuit
Inventor: MUTO SHINICHIRO
IPC: G11C11/412
Filed: 1991-12-09
Abstract: PURPOSE:To attain high integration of a memory by a method wherein memory cells selected by row address selection signals and column address selection signals are disposed in the shape of a matrix and the memory cells adjacent to each other in the row direction are connected to a common bit line. CONSTITUTION:When a row address selection line RA2 and a column address selection line CA2 are selected, only a memory cell M5 connected to both of them is selected. Then an operating current flows to a low-potential power source in the cell M5 from either one of bit lines BL2 and BL3 connected to a node wherein low-potential information is stored, and the potential thereof lowers. Although a memory cell M6 is connected to the bit line BL3 of which the potential lowers, the information stored in the cell M6 is not affected by the potential of the bit line, since a column address selection line CA3 is not selected. According to this constitution, the total number of bits of the whole memory cell array is reduced to n+1.

IPC: G02B6/00
Filed: 1994-12-27
Abstract: PURPOSE: To obtain a uniform illuminance by using one or plural optical fibers which have a bending angle larger than a specific angle for a projection part. CONSTITUTION: Light emitted from an optical fiber 2 has a large angle of >=15 deg. to the axis of the optical fiber 2 because of characteristics of a light source 1 and this light is made incident on the optical fiber 3 for the projection part. The light made incident on the optical fiber 3 for the projection part is made incident on a optical fiber of the core of the optical fiber 3 and reflected repeatedly by the border of the core and clad, so that the light having a large angle is converted into light having a small angle. Here, the optical fiber 3 for the projection part has a bending angle of >=30 deg.. Consequently, dispersion in light mode is caused in the optical fiber 3 for the projection part and the rate of the large-angle light becomes similar to that of the small-angle light.  For the purpose, the light is passed through the optical fiber 3 for the projection part to disperse the angle of the one-sided light and similar intensity is obtained at any angle, thereby making the illuminance distribution of optical fiber lighting uniform.
