Title: Synthesis of cyclic peptide
Inventor: UENO YUKIO
IPC: C07K1/04
Filed: 1991-07-17
Abstract: PURPOSE:To produce a highly pure cyclic peptide in a high yield in a short time by forming a peptide chain on an insoluble carrier comprising an oxime group-introduced resin by a solid phase method, binding both the termini of the peptide in the presence of an acid and an amine to form a ring. CONSTITUTION:By a solid phase mthod using an insoluble carrier comprising an oxime group-introduced resin, amino acids whose alpha-amino groups have been protected with t-butyloxycarbonyl groups, etc., are successively baund to the insoluble carrier by amino acid coupling reactions in accordance with the amino acid sequence of a peptide chain. The synthesized peptide chain is released and simultaneously subjected to a ring-forming reaction between both the termini of the peptide chain in the presence of an acid (e.g. acetic acid) and an amine (e.g. triethylamine) to produce the objective cyclic peptide whose main chain has the cyclic structure. The acid and the amine are desirably empolyed in amounts of 1-10 times that of the peptide on the insoluble carrier.

Title: Driving system of liquid-crystal display device
Inventor: FUTAHARA MASAYOSHI
IPC: G02F1/133
Filed: 1983-10-31
Abstract: PURPOSE:To eliminate the need for adjustment by a variable resistance, etc., even when a shift in the position where liquid crystal is viewed occurs by supplying a driving voltage which varies at a specific period from a power circuit to the driving power terminal of a liquid-crystal display device. CONSTITUTION:The liquid-crystal display device 11 is applied with a voltage (VDD-V0) between its power terminal VDD and driving terminal V0. An AC voltage (v) from an AC waveform generating circuit 16 is superposed upon a DC voltage supplied from the variable resistance 14 through a capacitor 15 for coupling. Therefore, a voltage varying by the variation value of the AC voltage (v) about the voltage V0 is applied to the driving power terminal V0 of the display device 11. The driving voltage varies with time, so the angle of vision to the display device 11 varies with time to obtain a display which is easy to see from any position. Therefore, the adjustment by the variable resistance, etc., is unnecessary.

Title: Insulation diagnosing method for oil-immersed electric equipment
Inventor: FUKAMACHI TETSUO
IPC: G01R31/12
Filed: 1989-08-05
Abstract: PURPOSE:To conduct an insulation diagnostic test with a low applied voltage by substituting insulating oil which is an insulating medium with insulating gas and setting absolute pressure so that its dielectric strength is lower than the dielectric strength of the insulating oil. CONSTITUTION:The level of an applied voltage which causes partial discharge in an insulator 3 depends upon the dielectric strength of the insulating medium. Then gaseous sulfur hexafluoride filling a tank 2 instead of the insulating oil has dielectric strength equivalent to that of the insulating oil when the absolute pressure is about 4 kg/cm<2> and as the pressure is lowered,k the dielectric strength also decreases at about its 0.8-power ratio. For the purpose,k wheh a gas pressure controller sets the pressure to about 1-0.5 kg/cm<2>, the dielectric strength becomes about 1/3-5 times as large as that of the insulation oil. If there is an abnormal plase in the insulator 3, partial discharge is caused with a lower applied voltage to detect whether or not there is abnormal insulation in an oil-immersed transfromer 1 with the lower voltage and the energy of the partial discharge is small, so influence upon the insulator 3 is small. Further,k a voltage applied to a high-voltage bushing 6 is low, so the influence of an external noise is suppressed and the detection sensitivity increases.

Title: Cassette loader
Inventor: MATSUMARU MASAHIRO

Filed: 1990-07-30
Abstract: PURPOSE:To selectively load a large or small cassette by suspending a freely rotatable drive shaft over an upper part of a cassette holder and fitting this shaft with a lid opener mechanism for a small size cassette to be capable of oscillating in the direction of inserting the small size cassette and also engaging with a lid of the small size cassette. CONSTITUTION:When the small size cassette C1 is inserted into a prescribed position inside the cassette holder 40 from a cassette inserting hole 30 of the front panel of the VTR main body, the drive shaft 101 is rotated by a drive shaft rotating mechanism, and hence the lid opener mechanism 130 for the small size cassette C1 is oscillated over the upper part, thus opening the lid of the small size cassette C1. Then, when the large size cassette C2 is inserted, the lid opener mechanism 130 for the small size cassette C1 is sprung up upward by advancing movement of the large size cassette C2 to allow the large size cassette C2 to advance. By this method, the large and small cassettes having nothing in common about their sizes and lid structures can selectively be loaded.

IPC: G03F7/20
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce an illuminance unevenness on the surface of a reticle by the simple constitu tion of a scanning exposure device and to facilitate a projecting and exposing operation by a high-resolving power and moreover, to a large screen by a method, wherein the direction of the low coherence of a lighting luminous flux is set in a such a way as to roughly coincide with the scanning direction of the reticle and the lighting luminous flux is vibrated in the direction of high coherence. SOLUTION: The luminous flux in a direction V out of luminous fluxes, which are emitted from a light source 1 and have anisotropy in a coherence, is low in coherence and the luminous flux in a direction (h) is high in the coherence. There, the light source 1 is installed in such a way that the direction V of low coherence of the luminous flux coincides with the scanning direction SC of a reticle 9 on the surface of the reticle 9, while strong interference fringes, which are extend in the scanning direction of the reticle 9, are vibrated by a vibration applying means 20 in the direction (non-scanning direction) of high coherence within a plane, on which a uniformizing means 4 orthogonally intersects the luminous flux, and the uniformity and the balance in the non-scanning direction on the surface of the reticle 9 are conformed to each other to eliminate the interference fringes.  Thereby, a uniform lighting is obtained, extending over the whole surface of a substrate 11, and a high-resolution exposure and transfer process to a large screen becomes possible.
