Title: Train electrode drive circuit for matrix type liquid crystal display device
Inventor: TAKEDA MAKOTO
IPC: G02F1/133
Filed: 1987-12-07
Abstract: PURPOSE: To display an excellent image without image disorder by repeating operation for counting a clock signal as many times as the number of stages of a shift register by the number of times set from outside, and then outputting a sample signal to the shift register. CONSTITUTION: A sample signal generating circuit 15 of a shift register control circuit 14 inputs the same clock signal ϕ as a clock signal inputted to a shift register circuit 11 and a timing signal S prescribing the start position of sampling. The circuit 15 generates one sample signal C right after the signal S is inputted, and then generates one signal C each time the clock ϕ4 is counted by the number (k) of stages of the circuit 11 and outputs the signal C to a timing selecting circuit 16. The circuit 16 takes only a 1st pulse out of a series of pulses of the signal VC and outputs it as a sample signal D to the circuit 11. Thus, respective cascaded LSIs generate sample signals of the same timing and an excellent display image can be obtained without disorder due to noise.

Title: Turning controlling circuit of construction machinery, etc.
Inventor: TSUKAMOTO HIROYUKI
IPC: E02F9/22
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To smoothly control a turning controlling circuit without feeling any sense of disharmony even in a normal mode by providing a detector for detecting stroke end time and inflection point time and a controller for smoothing variations in discharge after the detection. SOLUTION: When a control lever 8 is turned down to the right side in a normal work mode, pilot pressure occurs in an oil passage 6. A spool of a selector valve 4 states to move on the right. At the same time, oil pressure in the oil passage 6 is detected with a pressure sensor 33 through a shuttle calve 31 and an oil passage 34. Successively, the beginning of control is informed with an arithmetic circuit 37. Then, a control signal generating section 39 outputs a certain current of signals in correspondence therewith. Then, an electromagnetic proportional reducing valve 41 supplied pressure oil with constant pressure to a limiting port 18f of a regulator 18. After the stroke end time, controlling signals are reduced to lower also output pressure.  Accordingly, pistons 18a and 18b are gradually moved, and during the period of time, discharge of a pump 1 is also increased to increase smoothly the velocity of a motor 9. By the constitution, smooth control can be made.

Title: Film unwinding device
Inventor: UIRIAMU JIEEMUZU GURIIN
IPC: G03D13/00
Filed: 1992-11-19
Abstract: PURPOSE: To provide an unwinding device used together with a spool having a release preventing hook so as to release the bottom end part of a film from the spool as necessary. CONSTITUTION: The unwinding device is used together with the spool 5 having the hook which is actually extended in the winding direction W of the film and can be engaged with the hole of the bottom end part of the film, for preventing the release of the film F. The spool 5 is rotated in the unwinding direction U of the film F, together with it, to pull it out of the spool 5. At the time of pulling out the film F, an overlapped part is connected to the spool 5, so as to obtain rotation in the unwinding direction. When the film F except the bottom end part is pulled out of the spool 5, the overlapped part imparts momentum for rotating the spool 5 in the unwinding direction in the bottom end part, to release the hook from the hole, so that the bottom end part can be released from the spool 5, without tearing the film F.

Title: Method for dealing with sliming in service water
Inventor: TSUJI KATSUJI
IPC: C02F1/50
Filed: 1993-12-10
Abstract: PURPOSE:To appropriately and efficiently add and use a slime control agent for preventing sliming by measuring the consumption rate of oxygen retained in service water and controlling the addition of a slime control agent based on the result. CONSTITUTION:The consumption rate of the oxygen dissolved in service water is measured by sampling a part of the water mixed with a slime control agent in a substantially closed vessel, economically measuring the consumption of dissolved oxygen for 1 to 60min and calculating the measured value in terms of the value per hour. Since the measured oxygen consumption rate is closely correlated with the sliming, the control of the slime control agent, i.e., the selection of the kind of the agent, adding time and amt. of the agent to be added, is fulfilled by measuring the consumption rate with the passage of time.

Title: Illuminating device for liquid crystal display device and liquid crystal view finder device for video camera using this device
Inventor: JITSUKATA HIROSHI
IPC: H04N5/225
Filed: 1990-11-19
Abstract: PURPOSE:To obtain the high-luminance liquid crystal display device without increasing electric power consumption by providing an interference filter of a multilayered film structure formed by alternately laminating plural layers of >=2 kinds of optical thin films varying in refractive index from each other between a light source and the liquid crystal display device to increase the brightness in the front surface direction of the illuminating device. CONSTITUTION:Of the light released from a fluorescent tube 1, the light 4' reflected by a reflection surface 2 and direct light 4 are made incident through a diffusion plate 3 on the interference filter 5. The ray (theta<30 deg.) 11 of the small incident angle theta on the filter 5 transmits the interference filter 5 and is emitted forward. The ray 11' (theta<40 deg.) of the large incident angle theta is, however, reflected by the interference filter 5 and is returned as the ray 11'' to the diffusion plate 3 side. This ray 11'' is diffused by the diffusion plate 3 and is reflected again to the interference filter 5 side, by which the incident angle theta is diminished. This ray repeats reflections any times between the diffusion plate 3 and the filter 5 until the ray transmits the interference filter 5. Consequently, the rays transmitting the interference filter are increased in the component near the normal of the filter and the brightness of the illuminating device viewed from the front surface is improved.
