Title: Illuminator for projection type liquid crystal projector
Inventor: MIHARA HISAYUKI
IPC: H04N5/74
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain high-quality illumination at low cost even when a fly-eye lens is used and to miniaturize the fly-eye lens by constituting the lens array of the 2nd fly-eye lens corresponding to the eccentric amount of the lens array of the 1st fly-eye lens. SOLUTION: Almost parallel beams obtained by a parabolic mirror 15 are divided into plural by the 1st fly-eye lens 21 so as to average luminance unbalance by plural main light beams generated by the 1st fly-eye lens 21. Furthermore, the light is formed into an image in an optical axis direction, diffused corresponding to the eccentric amount of the lens 21 by the 2nd fly-eye lens 23, controlled to be the almost parallel beams by a condensing lens 25 and made incident on an entire liquid crystal light valve 125. Therefore, the lens 23 is miniaturized. Since unbalance in up-and-down and right-and-left directions is average so that luminance may be negated, irregular light emission mainly caused by a light source lamp 11 is reduced.

Title: Electrolyte circulation type zinc-bromine battery
Inventor: SASAKI TORAHIKO
IPC: H01M12/08
Filed: 1989-03-28
Abstract: PURPOSE:To suppress the rise of pH of an electrolyte by storing a carbon material in a small chamber in a positive electrode side electrolyte circulating passage, and reacting the free bromine in the electrolyte and water using the carbon material as a catalyst to generate hydrogen bromide. CONSTITUTION:A small chamber 46 partitioned by a polyolefin fine porous film is arranged in part of a positive electrode side electrolyte storage tank 22, and a carbon material 49 is stored in the small chamber 46. The polyolefin fine porous film is used as the separator film of a zinc-bromine battery, water and free bromine permeate it, but a lipophilic bromine complex compound rarely permeates it. Free bromine and water are reacted via a carbon material 49 serving as a catalyst in the small chamber 46 partitioned by the translucent fine porous film to generate hydrogen bromide. The rise of pH of the electrolyte can be effectively suppressed without consuming the bromine complex compound.

Title: Encoder for picture signal
Inventor: SEMASA TAKAYOSHI
IPC: H04N1/41
Filed: 1981-05-20
Abstract: PURPOSE:To remarkably simplify a line for code processing, by inputting signals representing forecasting values with a limited number fewer than the number of color levels and a noted picture element signal, and forming a forecasting error signal. CONSTITUTION:Picture signals of adjacent picture elements A-D are inputted in each 3-bit to input terminals A11-A0 of an ROM 1a, and forecasting values (Xr, ) and (Xr, ) are given to an ROM 3 together with the picture signal of a noted picture element X. The ROM3 forms forecasting error signals Y7-Y1 based on the given input signal. In forming forecasting error signals to encode the picture signals, signals of noted picture elements and forecasting values with a limited fewer number than that of the color levels are inputted and the forecasting error signals are formed, allowing the storage capacity of the ROMs to be reduced remarkably without increasing the number of code bits.

Abstract: PURPOSE: To determine the stray capacity between coupling electrodes, the coupling capacity between the coupling electrode and a test material, and the resistance of the test material by feeding an AC current from two coupling electrodes to the test material and measuring total impedance at three frequencies. CONSTITUTION: An AC current is fed from two coupling electrodes 2, 3 to a test material 1.

On the other hand, the imaginary part of total impedance is measured using a low frequency AC power supply and the coupling capacity CK between the coupling electrodes 2 or 3 and a test material 1 is determined while taking account of the stray capacity CS. Subsequently, the real part of total impedance is measured using an AC current between the high and low frequencies for minimizing the phase shift. Finally, the resistance R of the material 1 is determined while taking account of the stray capacity CS and the coupling capacity CK.  In order, to enhance the measurement accuracy furthermore, the test material 1 may be measured using two electrodes separated by different distances therefrom.

Abstract: PURPOSE:To reduce errors of detection by providing a means of detecting some of information units from plural units provided on a roll film in a feed direction simultaneously. CONSTITUTION:When a camera back is closed with the film 1 loaded, a switch 9 is turned on and a switch 123 is associated with it to clear a storage circuit 128.

Consequently, a signal is generated at a terminal (x) and the information of a decoder 126 is stored in the storage circuit 128. Then, the control circuit 127 inhibits the stored information from being updated.

Abstract: PURPOSE:To form a film on a large-area surface to be formed by providing an optical means to a substrate side from the light source in a light source chamber to intensify the intensity of the photo-irradiation in a reaction chamber. CONSTITUTION:A substrate 1 is disposed on a substrate holder of the CVD device. The light from the light source 9 provided in a light source chamber 6 is transmitted through a light transmission window 10 and is projected to the reaction chamber 2. The window 10 is provided with such a function as lens to condense the light transmitted through the window 10 near the substrate 1. Gas, such as nitrogen, is forcibly circulated in the light source chamber 6 by a circulator 12. The nitrogen is controlled at a certain temp. by a cooler 13 in the flow passage for circulation. The temp. rise arising from the light emission of the light source 9 is suppressed and the change in the wavelength of the emitted light is not admitted. The light of the wavelength necessary for the stable reaction is thus outputted. The film forming speed is increased in this way and the threshold film thickness on the substrate 1 is improved.
