Title: Bonding of flat boards
Inventor: TEJIMA AKITOMO
IPC: H01L21/20
Filed: 1987-07-03
Abstract: PURPOSE:To realize a bonding operation of flat boards without being contaminated with impurities, with good thermal resistance and with few stresses and little distortion due to heat by a method wherein a heating operation is executed in a state that surfaces of hydrogenated amorphous silicon layers formed on the individual flat boards are brought into close contact with each other. CONSTITUTION:If a temperature is raised in a state that a-Si:H layers 2, 2' which have been applied to surfaces of a pair of flat boards 1, 1' are brought into close contact with each other, hydrogen is dissipated and, simultaneously, dangling bonds of a-Si are coupled and a bonding operation is executed. This is realized only when a-Si:H containing hydrogen is used. In addition, because the hydrogen is dissipated easily to the outside, there is no fear of being contaminated with impurities; because a bonded layer is in an amorphous state, a stress is easily absorbed; there are few possibilities that the bonded layer has a bad influence on Si to be used to form a thin-film device.

IPC: G02B5/18
Filed: 1993-07-07
Abstract: PURPOSE:To make it possible to adjust the degree of eliminating the dots of picture elements and the degree of degradation of resolution in compliance with a video or personal subjectivity by changing the distance between a liquid crystal display element and an optical low-pass filter. CONSTITUTION:The liquid crystal display element 101 is fixed to a lens barrel 104. The position of a diffraction grating (optical low-pass filter) 102 is changed in the lens barrel 104 by moving a knob 103 for adjusting the position of the diffraction grating forward and backward from the outside. The degradation in the resolution is lessened although the effect of eliminating the dots of the picture elements is small if the distance between the diffraction grating 103 and the liquid crystal display element 101 is reduced by moving the knob 103 toward the liquid crystal display element 101 side. The black mask between the picture elements of the liquid crystal display element 101 is obscure at this time, but the dots of the picture elements are not completely eliminated. The sepn. width of the picture elements is increased if the knob 103 is moved to the lens 105 side and, therefore, the dots of the picture elements are obscure but the resolution of the display degrades little by little.

Title: Constant current circuit
Inventor: AOKI HIROSHI
IPC: G05F3/24
Filed: 1986-07-17
Abstract: PURPOSE:To obtain a stable constant current characteristic by absorbing the change of an power source voltage with the second and fifth MOS transistors. CONSTITUTION:Since MOS transistors T3 and T2 are connected by a diode, the voltage between respective source gates is held the constant voltage of about 0.5V without depending upon the electric power source voltage. Since the gate voltage of a MOS transistor T6 is also held to an approximately constant voltage without depending upon the power source voltage, a source drain voltage is also held to the constant voltage of about 0.5V. Namely, since MOS transistors T2 and T5 exist, most of the change part of the power source voltage is displayed at the drain of the transistors T2 and T2 and at the source of the transistors T2 and T5, the influence of the change of the power source voltage is hardly displayed. Consequently, for a resistance R, the resistance with a small resistance value can be used, for transistors T2, T3, T5 and T6, the transistor with a short channel length is used, and even then, a stable constant current characteristic can be obtained.
