Title: Driving of liquid crystal display panel
Inventor: YASUI MASARU
IPC: H04N9/12
Filed: 1987-09-24
Abstract: PURPOSE: To prevent vertical resolution from decreasing by storing video signals in 1st-4th storage devices so that their color array for respective source driving lines match a color array of color elements in rows of a display panel to be displayed in the former half of one next horizontal period and rows to be displayed in the latter half. CONSTITUTION: During driving by a 1st couple of two storage devices out of the 1st-4th storage devices, a video signal of one horizontal period is stored in a 2nd couple of the remaining two storage devices and during driving by the 2nd couple of storage devices, a video signal of one horizontal period is stored in the 1st couple of storage devices. Then video signals are stored in the 1st-4th storage devices so that the color array for respective source driving lines 111 -11n matches the color arrays of color elements in rows of the display panel 1 to be displayed in the former half of the next one horizontal period and rows to be displayed in the latter half. Consequently, the vertical resolution is not decreased.

IPC: C07F7/18
Filed: 1993-09-01
Abstract: PURPOSE: To obtain a new color photographic recording material which can increase the stability of magenta dye by incorporating specific compds. as magen ta coupler and photostabilizer therein. CONSTITUTION: This color photographic recording material usually contains the stabilizer of the magenta dye in blue photosensitive and/or green photosensitive and/or red photosensitive silver halide emulsion layers and, if desired, protective layer and green photosensitive layer.

Title: Coil inserting device
Inventor: MURAI TOSHIAKI
IPC: H01F41/00
Filed: 1988-09-28
Abstract: PURPOSE:To insert a coil easily and densely by a method wherein a chuck holder unit provided with two chuck pawls for each lead of a coil is provided and the space between the chuck holder units is regulated. CONSTITUTION:A closing-opening action of two chuck pawls 50 and 50' for holding or releasing a lead is a linear movement in a direction leaning with the plane of a printed board 62 in which an insertion hole 63 has been previously bored. Thereby, the interference between adjacent components and the pawls 50 and 50' can be eliminated. The space between chuck holder units C with the chucks 50 and 50' provided facing each lead 61 is regulated by a unit space control device D corresponding to the lead pitch of a coil. By this setup, the leads of a coil 60 of different lead pitches can be easily held with pawls.

Title: Crt driving circuit
Inventor: MATSUMOTO KENJI
IPC: H04N5/68
Filed: 1987-09-28
Abstract: PURPOSE:To obtain a large driving voltage when an operational amplifier with a small output voltage is used by supplying a signal passing through the operational amplifier to output the signals of mutually opposite phases between the grid of a CRT and a cathode. CONSTITUTION:An operational amplifier 3 inversion-amplifies an input signal up to the full of positive/negative supply voltages, supplies an output signal to the cathode of a CRT 9, an operational amplifier 2, in the same way, non- inversion-amplifies the input signal from an offset reference level, and supplies the output signal through a capacitor 8 to the grid of the CRT 9. Since the separately amplified signals are supplied to the grid and the cathode, and the signals are mutually at opposite phases, when the gains of the operational amplifiers 2 and 3 are the same, the signal voltages between the grid and the cathode are added with the respective operational amplifier outputs, and the value of them becomes the double of the one operational amplifier output voltage. Consequently, when the operational amplifier with the small output voltage is used, the signal voltage between the grid and the cathode becomes the large value.

Title: Manufacture of semiconductor element
Inventor: KIYOHASHI KAZUO
IPC: H01L21/301
Filed: 1988-09-26

CONSTITUTION:An n type gallium phosphide arsenide and epitaxial layers 2 are laminated on an n<+> type gallium arsenide board 1 whose facial direction is 100. A groove 3 is formed in succession by etching the surface of an n<+> type gallium arsenide side of the board. p-n joining is formed on the epitaxial layer 2 in succession and light emitting, diodes 4001-4128 are formed. Then after formation of an ohmic electrode on a p-side, the ohmic electrode on an n-side is formed. Then the n-side of the board is stuck to an adhesive tape 5 and the board is diced with a thin blade 6 of a resin material. In this instance, a distance is set up between an end of the blade 6 and the adhesive tape 5. Dicing/cutting of a separating and cutting allowance part in the direction running parallel with an arrangement direction of the luminescence diode are performed with the blade.

Title: Frequency dividing circuit and filter circuit
Inventor: SHIRAKAWA HIROSHI
IPC: H03K23/00
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To secure almost the same duty ratio for the frequency divided output signals despite the odd frequency division and also to attain a fast frequency dividing operation. SOLUTION: A D flip-flop 11 operates at the rise of a clock CK and sets its output signal Q1 at a high level. Then the flip-flop 11 is reset and the signal Q1 is set at a low level when the clock CK is set at a low level and the output of an OR circuit 16 is also set at a low level. Thus the signal Q1 is used as a 3 frequency dividing signal of the clock CK. A D flip-flop 12 is controlled in an operable state and a reset state by the signal Q1, and the states of both flip-flop 11 and circuit 16 are controlled by an output signal Q2 of the flip-flop 12. Thus almost the same duty ratio is secured for the 3 frequency dividing signals. Furthermore, the frequency dividing speed is increased owing to the direct use of the clock CK.

Title: Semiconductor device
Inventor: KURODA TAKARO
IPC: H01L31/10
Filed: 1990-09-14
Abstract: PURPOSE:To avoid delay of a response while improving sensitivity by selecting a distance between a source and a drain formed with a thick undoped light absorption layer directly under an n-type doped layer. CONSTITUTION:If the thickness of an n-type layer is thin to 100nm or less and the thickness of a light absorption layer 32 is thick to 1-2mum when an FET is irradiated with a light, most photocarrier is generated in the layer 32. Thus, an extremely slow response due to holes optically excited directly in an n-type active layer 31 can be substantially eliminated. Parts of the holes are attracted by the negative bias of a gate electrode to be introduced into a depletion layer 6, thereby inducing a phototransistor operation. After the other holes are once introduced to the layer 31 between a source electrode and a gate electrode, they are attracted to a gate voltage and diffused in the layer 6 to be removed. If an interval between the source and the gate is made shorter than the diffusion distance of the holes, the holes can be drawn toward the gate at a much shorter time than that in which the holes are erased due to the lifetime.

Abstract: PURPOSE:To eliminate a bad influence of a speed correction to a lead-in time of a phase control by executing a self-correction of a speed offset, subsequently, cutting it off, and simultaneously, starting to perform the phase control. CONSTITUTION:A motor 21 inputs a signal from a speed controlling circuit 23, a speed correcting circuit 24 and a phase detector 28 and a signal from a reference signal input terminal 29, to an adder 26 through a phase controlling circuit 25, by a signal obtained by a frequency generator 22, and its driving is controlled through a motor driving amplifier 27. As a result, when a switch 44 of the phase controlling circuit 25 is closed by an output of an error detector 39 from the speed correcting circuit 24 and the phase conrol is executed, a rotational phase of the motor 21 synchronizes with that of a reference signal REF. Also, thereafter, a phase comparing data is applied to the error detector 39 by setting a switch 38 to the C side, and a phase offset is detected. By this offset quantity, a correction is applied to a speed control system digitally, and the phase offset is corrected automatically.
