Title: Non-superimposed scanning method for pair of scanning lines for liquid crystal display device
Inventor: FUAN CHIEN KUO
IPC: G02F1/133
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To eliminate the luminance change of a pixel caused by a parasitic capacitance by scanning row selection lines with a pair in a horizontal scanning period and pairing the selected row selection lines while being shifted by one scanning line in respective fields of odd number and an even number. SOLUTION: Row selection lines are driven by the periodical voltage pulse train of a jump mode. The width 52 of a selection voltage pulse is shorter a little than the half of the horizontal scanning period 50. Each frame scanning period is divided into an odd numbered field constituting the first half of the frame scanning period and an even numbered field constituting the second half of the frame scanning period. The voltage pulse is at a voltage level VGH 60 when the row is selected and at a voltage level VGL 62 when the row is not selected. In the odd numbered field, the same video data signals are impressed to the row selection lines, and in the even numbered field, the same video signals are impressed to the row selection lines since the signals are shifted by the one scanning line.

Title: Infrared rays image pickup optical system
Inventor: SHINZOU TOORU
IPC: G03B41/00
Filed: 1990-11-06
Abstract: PURPOSE:To reduce influence of narcissus effected on a photographing object without altering design value of each optical element by modifying the configuration of an aperture diaphragm to a sawtooth shape. CONSTITUTION:The infrared rays radiated from an aperture diaphragm 6, made in a sawtooth shape along the effective diameter portion, reflects by the back side of a negative lens and an image-formation is conducted at an infrared detecting portion 5. However, using the sawtooth shaped aperture diaphragm 6 causes the high frequency component to increase as the spatial frequency approaches an optical axis at the effective diameter portion and a narcissus image becomes obscure because the high frequency components are eliminated by the optical capacity which forms narcissus image. The amount of transmitted light at the aperature diaphragm surface gradually reduces as it becomes more distant from the optical axis near the effective diameter. For this reason, the edge portion of the narcissus image becomes a gently-sloped contrast variation thus reduces the influence of the narcissus effected on a photographing object.

Title: Photodetector and photodetecting device equipped with it
Inventor: KOGO ATSUSHI
IPC: G01J1/02
Filed: 1991-11-15
Abstract: PURPOSE:To obtain an accurate detected value without requiring skillfulness even when light to be detected outside the visible ray region is to be detected by providing a displaying means which indicates the spot of the light to be detected outside the visible ray region by emitting light or coloring in the periphery of a light receiving section. CONSTITUTION:When a light receiving section 1 is irradiated with light 5 to be detected, a photoelectric conversion signal is outputted from this photodetector 2. The output signal is displayed on an output displaying section 4 through an output transmission cable 7. In case a generating member 3 is irradiated with light outside the ultraviolet ray region when the section 1 is irradiated with the light to be detected, the spot 6 of the invisible light 5 is indicated by the light emitted from the member 3, because the irradiated part of the member 3 contains such a substance as pyrene, berylene, etc., which emits light when the substance is irradiated with light in an invisible ray region. Therefore, since the spot 6 can be brought into the light receiving section 1 by moving the photodetector 2 while the position of the spot 6 is visually confirmed, the light 5 to be detected can be accurately detected with the photodetector 2.

Title: Rotational speed controller of motor
Inventor: MIZUGUCHI HIROSHI
IPC: H02P29/00
Filed: 1987-11-27
Abstract: PURPOSE:To reduce the number of addresses for a data memory by detecting a peak position of periodic variation in a mean speed measured value of a motor and deciding a storage starting address of section data to the data memory on the basis of the position to be detected. CONSTITUTION:A counter 20 measures an interval for every period of a speed signal FG, and outputs a mean measured value in an instrumentation section. A data memory 11 stores in an address selected by the output of a ring counter 10 to count a signal obtained by demultiplying the speed signal FG, section data based on the mean measured value. An adder 21 adds the output of a counter 20, a reference value from a standard generator 15 and the output of the data memory 11, and outputs error data. Accordingly, a synchronized block 40 detects a peak position of periodic variation in the mean measured value, and the ring counter 10 is initialized on the basis of the position.

Abstract: PURPOSE:To facilitate the recognition of a mode and to accurately perform the input of a character by using a liquid crystal plate at the part of a key arranging plate, and performing the inverted display of the character at the upper part of a key validated by switching the mode. CONSTITUTION:By depressing a shift key 8, an input KANA (Japanese syllabary) mode can be designated, and all of the valid characters on the liquid crystal plate 6 are displayed inversely, and by depressing a key 9, a valid character 'A' (one of Japanese syllabary) can be inputted in a designated mode. Next, by switching the mode by depressing the shift key 8 again, all valid characters in the mode can be displayed inversely, and by depressing the key again, a valid character 'HA' (one of Japanese syllabary) in the mode can be inputted. Thus, by switching the mode by depressing the shift key, the mode can be recognized easily since the mode and the valid character are integrated visually, and the input of the character can be performed accurately.

Title: Fault detecting device for information processor
Inventor: NAKADA HIROAKI
IPC: G06F11/22
Filed: 1988-11-29
Abstract: PURPOSE:To detect a processor, where fault occurs, without always monitoring status information of each processor by a diagnosing processor by performing the diagnostic processing of the processor where fault occurs based on processor specifying information from a fault detecting circuit. CONSTITUTION:When fault occurs in a processor 24, the processor 24 sends fault information to a fault detecting circuit 11. The fault detecting circuit 11 receives this fault information to recognize the occurrence of fault in the processor 24 and sends specifying information of this processor to a diagnosing processor 12. The diagnosing processor 12 which receives this processor specifying information performs a proper diagnostic processing of only the processor 24 where fault occurs. Thus, it is unnecessary to always monitor each processor by the diagnosing processor 12, and fault is detected in a short time.

Filed: 1993-11-09
Abstract: PURPOSE:To enable high-efficiency collection of hydroxyacetone of high purity by distillation of crude hydroxyacetone in the presence of alkylnaphthalene. CONSTITUTION:For example, propylene glycol is catalytically dehydrognated to give a crude hydroxyacetone solution. At least one of alkylnaphthalene is added to the crude solution and the mixture is distilled at 30 to 80 deg.C column bottom temperature under the pressure of 2 to 250mmHg to give hydroxyacetone of high purity.
